When I first came into contact with the computer a long time ago, the computer did not seem to have a USB Cable interface. At that time, external devices such as printers, keyboards and mice were connected to the computer with interfaces of various shapes, colors and shapes. Before the emergence of USB data cables, the above-mentioned connecting cables were commonly used in the market, and had many disadvantages. First of all, different devices need to be connected with different connecting cables, and almost none of these interfaces support hot-swapping, and cannot be plugged and played. To use it, you have to repeatedly debug and configure it before it can be used. Often, if you don`t pay attention to the lower right corner of the computer, it will prompt that it does not support power supply and other shortcomings. Over time, these inconvenient interfaces gradually disappeared, and finally the advent of USB solved the above problems. It can be hot-swappable, and plugging and unplugging when the computer is turned on does not affect the use without debugging; it can be plug-and-play, and can be recognized and read immediately after plugging in, without configuration; it can also charge external devices. This may be the reason why the USB data cable can become one of the most enduring interfaces: universal! With the advancement of science and technology, products are constantly being introduced. The USB interface is also slowly improving, and there are also MINI USB and the like. There are three types of classification of USB interface data lines: without IC, with IC, special chip. Without IC: There is no central control chip, you must plug in your mobile phone and computer to recognize the line, and the price is cheap. Special chips: non-ordinary popular chips, dedicated special type chips With IC: With a central control chip, it can recognize the line without plugging in a mobile phone or a computer. Since the price of an IC is more than 10 yuan, the price is more expensive than that without an IC. The working principle of the data cable with a chip is USB to COM, which converts the USB interface into a serial port and displays it on the computer. If you still want to know more about data cables and USB Type C adapter cables, please contact us and we will serve you wholeheartedly.

The USB Type C data cable is used as the connector between the latest electronic devices or between the electronic device and the power supply. The material selection of the connecting cable is very important. If a poor-quality connecting cable is used, it will lead to prolonged charging time, unstable data transmission, and breakage and other hidden dangers, and may even lead to the scrapping or explosion of electronic equipment. The choice of data cable material determines the service life and safety of the data cable. What are the advantages and disadvantages of data cables made of different materials? 1. PVC data cable Polyvinyl chloride, referred to as PVC (Polyvinyl chloride), is an initiator of vinyl chloride monomer (VCM) in peroxides, azo compounds, etc.; or under the action of light and heat according to the mechanism of free radical polymerization aggregated polymers. Advantages of PVC data cable: 1. Low cost, good insulation performance and weather resistance; 2. The price of PVC data cable is relatively cheap. Most of our USB Cables are made of this material. 2. TPE data cable TPE material is a material that has the high elasticity, high strength and high resilience of rubber, and has the characteristics of injection molding. Advantages of TPE data cable: 1. Excellent processing performance, excellent colorability, soft touch, weather resistance, fatigue resistance and temperature resistance; 2. Safe and non-toxic, no peculiar smell, and will not cause any irritation to human skin; 3. Can be recycled to reduce costs. 3. Nylon braided data cable Nylon has the characteristics of flame retardancy, high strength, wear resistance, and electrical insulation. Its plastic raw material is a translucent, white or black crystalline polymer with plasticity. Nylon has good strength and wear resistance. If you need Micro USB with this material, we also have it on sale. Advantages of nylon braided data cable: 1. Increase the beauty and external tensile capacity of the data line; 2. No spinning phenomenon, soft, bendable, very good resilience, not easy to tangle or crease; 3. Excellent durability, not easy to deform.

What kind of insulation material wire harnesses did the custom Wire Harness processing manufacturers use in the selection of wire harnesses? And what kind of requirements does wire harness processing have for wire harness insulation materials? Look at the functions and scope of use of PVC, PE, PP, XLPE, PU, TPE insulation materials in the wiring harness. PVC (our commonly used PVC lines are 1007\1015\1061, 1430, 1571)-polyvinyl chloride (PVC) plastic is a multi-component composite material based on polyvinyl chloride resin. Most of the USB Cables we produce use this material. According to the requirements of various wires and cables, plasticizers, stabilizers, fillers, flame retardants, processing aids (lubricants), ultraviolet absorbers, colorants and special-purpose additives are added to the PVC formula. For insulation and sheathing (mainly there are four temperature grades of 70, 80, 90, and 105 degrees). Basic determination method: When burning, yellow flame, black smoke, green flame at the bottom, foul smell. PE (our commonly used 3266\3385) - polyethylene has excellent electrical insulation (dielectric constant and dielectric loss tangent tgδ are very small), if you need this material, our DC Cable can also be customized. Excellent chemical stability, low air permeability and small water absorption, small specific gravity, non-toxic, and good plasticity, easy to process and shape. Mainly used for communication cable insulation. Basic determination method: the appearance is relatively bright. When burning, the flame is yellow on the top and blue on the bottom, dripping, and has a slight candle smell. PP--The appearance of polypropylene is white waxy solid, relatively transparent, non-toxic, low water absorption, only 0.03-0.04%, and flammable. The specific gravity is 0.91, which is the smallest of the commonly used plastics. Mainly used for core wire insulation. Basic determination method: the surface is relatively smooth, and compared with PE, it is harder. When it is burned, the flame will be yellow at the top and blue at the bottom, dripping, and there will be a smell, and there will be a slight candle smell afterward. XLPE/XL-PVC--thermosetting material, mainly used as insulation, the highest temperature resistance level of XLPE can reach 150 degrees. Fundamental identification method: cut a section of wire and remove the conductor, start burning from the middle with fire, and then pull the wire hard, the section is very round. PU--has good physical and chemical functions, and is often used as a sheath for connecting wires and spring wires of construction machinery and other equipment. Basic identification method: magnetic, good elasticity, swelling and dripping when burning. TPE/PO (Thermoplastic Elastomer) - low-smoke and halogen-free flame retardant.

What are the quality requirements of the DC Connector for the wire harness? Electronic connectors should conform to the specifications, increase the contact surface of the wires as much as possible, and avoid the implementation of hook connectors through terminals. First, the multi-strands should be fastened, and the filaments should not be exposed. The wires must be bent into a ring shape and placed in the On the terminal post, the washer screw on the pad, and the cover should be tightened, and the connection method is easy to use welding or crimping methods for connecting large-section wires and aluminum connection core wires. When crimping can be used, conductive paste can be applied. Copper-aluminum wire transition joints are easy to use copper-aluminum transition joints; it can also be joined with copper and aluminum. Put a thin layer of copper or tin on the copper lug, and connect it with aluminum wire. This realization can reduce the contact resistance. The position of the electronic wire connector is staggered. The joints of each phase line should be placed in a staggered manner. The outside of the adapter should be wrapped with a large cross-sectional area of black rubber band. The inside should be coated with yellow wax cloth or yellow wax cloth to improve the heat preservation performance. It cannot exist in electrical structures, luckily you must take precautions and pay attention to all the above steps to avoid fire accidents due to bad electrical connections. Oxidation of conductor joints In an ecological environment with humid and corrosive air, an oxide layer is easily formed on the conductor, and oxidized copper wires will appear on the copper. The conductivity of aluminum oxide is more likely to be formed on the aluminum wire. In the workshop, the wires of the DC Cable harness are corroded by acidic air for a long time, and the conductor forms an oxide layer on the surface, resulting in an increase in contact resistance. After turning on the power, high temperature will occur. We have Micro USB on sale, you can contact us if you are interested. We specialize in production and create premium quality.

For USB Cable, we use it every day, and it is also used in all aspects of electronic products. How to choose a USB data cable for different use requirements and different electronic products? When choosing a USB data cable, you should consider what the cable is used for and what electronic products it is used for. Here, the Lianxin Decheng data cable manufacturer divides the functions of the USB data cable into 4 categories: 1. USB data cable - high-speed transmission The USB cables on the market mainly include data cables such as USB 2.0, USB 3.0, USB 3.1, USB 3.2 and Thunderbolt. Different USB data cables have different transmission rates. When we choose, we should choose according to our own device interface speed and USB interface type. Such as USB Type-A to C data cable and USB Type C to C data cable. The transmission rate is different, the USB Type-A to C data cable can support USB 2.0, USB3.0, and the USB Type-C to C data cable can support USB 2.0, USB 3.0, USB 3.1, USB 3.2 and Thunderbolt, etc. . 2. USB data cable - video signal transmission If you want to use a USB data cable to transmit video signals, you must use a USB Type-C 3.x 10Gbps and above USB Type-C to C data cable. 3. USB data cable - fast charging When choosing a charging cable for the device, it should be confirmed that the device supports the fast charging protocol, and the USB data cable also needs to support the corresponding fast charging protocol to achieve the fast charging effect. Common fast charging protocols include: Huawei super fast charging, vivo dual-engine flash charging, QC2.0, QC3.0, PD fast charging and other charging protocols. Our data cable manufacturer has been focusing on the customized production of 3C digital cables for many years. We can customize and produce various USB data cables for customers, and can support a variety of fast charging protocols. Self-owned factory customizes direct supply, from copper wire drawing to finished product production, the whole production process is strictly controlled, in line with ROSH/CE/FCC and other standards. Customers are supported to submit drawings and samples to open molds and customize them. If you are interested, please contact us.

Environmental protection, as the name implies, is environmental protection, which means that human beings coordinate the relationship between human beings and the environment in order to solve actual or potential environmental problems; but for Type-C data lines, common environmental protection includes ordinary ROHS, REACH, NP, California 65, etc. Giving safety assurance to consumer groups has a direct relationship to human skin and the environment. Environmental protection also follows the progress of society, and gradually changes from non-environmental protection to environmental protection (ROHS). Our common ROHS is a mandatory standard formulated by EU legislation. This standard has been officially implemented on July 1, 2006. It is mainly used to standardize the material and process standards of USB Cable, making it more conducive to human health and environmental protection. The purpose of this standard is to eliminate six substances including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electrical and electronic products. RoHS is aimed at all electrical and electronic products that may contain the above six hazardous substances in the production process and raw materials mainly include: such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, audio and video products, DVDs, CDs, TV receivers, IT products, digital products, USB Type C, communication products, etc.; electric tools, electric electronic toys, medical electrical equipment, etc. Our data cable manufacturer can follow up customer requirements and tailor-made high-quality and low-cost USB Type B data cables. At the same time, it can meet various high-end environmental protection requirements to ensure that users care for themselves and their families; I believe that your purchase will give you unexpected Effect.

The rapid development of the mobile phone industry has brought a lot of convenience to our lives. At the same time, it has also driven the development of the mobile phone accessories industry, such as the USB Cable of mobile phones. Sometimes due to various reasons, several cables may be used in a year! Except for some situations like loss, sometimes when changing the data cable, it is likely that it is broken, or you are not satisfied with the charging effect! So how to choose a correct data line? The kind that charges quickly and is durable! 1. Fast charging We all know that when the current passes through the data line and then enters the mobile phone, there will be losses on the data line. And if you want to charge faster, try not to choose a data line that is too long, because the longer the current, the greater the loss on the data line, and the lower the charging efficiency. Secondly, the core material of the data line will also affect the charging efficiency. Generally, pure copper material will charge faster. 2. Durability It is also very annoying that the data cable breaks after not being used much. You might as well try a USB Type C data cable, which can be used blindly to increase the service life. The durability generally depends on its internal and external aspects. The internal wire material, craftsmanship quality, etc. will affect its lifespan. Although it is invisible to the naked eye, this generally has a great relationship with the price, so it is easy to judge. Another aspect is the external material of the data cable. There are many common plastic materials, which are soft and skin-friendly, and stylish and beautiful. But in terms of durability, it is not as durable as nylon braid. There are even data cables with metal coats, which should be more durable, and you can choose according to your needs! 3. Apple data cable Apple is different from other mobile phones. If the data cable does not have Apple MFi certification, it cannot provide charging for Apple devices. The data cable certified by Apple will be loaded with an authentication chip, which will be recognized by the Apple system. Therefore, pay extra attention when purchasing, whether the data cable has Apple's MFi certification. In addition, don't try to buy a cracked version of the MFi certified data cable for cheap, because once your device system is upgraded, this type of data cable will not be recognized and will not be able to charge. Secondly, this kind of uncertified data cable also has many hidden dangers, so it is not recommended to use it! I still have to say one more thing, you get what you pay for, and so does Wire Harness. As a commonly used mobile phone accessory, if the quality is not good, it may need to be replaced frequently. It is better to buy a good one, which can last for a long time. The key is peace of mind!

The connection between the various devices in the audio system, the connection between the microphone, the speaker and the device must use a connecting line, that is, DC Cable. The cable used in the system connection is not only related to the signal-to-noise ratio of the entire system, but also the material of the cable and the characteristics of the sub-parameters have a great impact on the sound quality. According to the different signals transmitted, the cables used in audio engineering can be divided into three categories: the first category is weak signal transmission cables, mainly referring to microphone cables; the second category is level signal transmission cables, used for various The connection between class equipment: the third class is the power signal transmission cable, that is, the speaker cable. Several types of cables are introduced below. (1) Microphone cable The microphone wire must be a shielded wire, because the microphone wire transmits a millivolt signal with a very low level. In order to prevent electromagnetic interference from the environment, shielding measures must be taken. There are two-core shielded wires and single-core shielded wires. Two-core wires can be used for balanced transmission, while single-core wires can only be used for unbalanced transmission. In addition to the requirements for anti-interference, the microphone cable also has requirements for mechanical characteristics. Due to the constant movement of the microphone, the microphone cable is easily pulled and tangled. For this reason, it is required that the microphone cable should be softer than the general shielded cable, and fiber wire should be added to the cable to improve the tensile strength. Microphone cables with tight metal shielding, soft texture, and fiber cables should be selected for audio engineering. (2) USB Cable line level signal transmission line Cable level signal transmission lines are used for the connection between the various devices in the electro-acoustic sound system. These connecting lines should also be shielded to prevent interference. Line-level signal transmission lines have no special requirements on mechanical characteristics, and ordinary shielded lines can be used. But the material of the wire will have some influence on the sound quality. Therefore, the line-level transmission lines used in audio engineering should try to use oxygen-free copper (OFC) lines, which not only help to improve sound quality, but also have a reasonable price. (3) Audio Connector cable In the connection between the power amplifier and the speaker of the professional audio system, it is generally desirable to have a larger value of the damping characteristic FD. Factors that affect the FD value include the impedance of the frequency division circuit of the speaker and the internal resistance of the speaker connecting line. The power amplifier should reduce the output internal resistance as much as possible to increase the damping coefficient to enhance its ability to control the speaker. The resistance of the speaker wire can be regarded as a part of the output resistance of the power amplifier. When the speaker wire is too long, its resistance value may greatly reduce the damping coefficient. First of all speaker wire should have the lowest possible resistance. This is especially important in audio engineering, because longer speaker wires are often used in audio engineering, and their resistance cannot be ignored. Therefore, the speaker wire should be as thick and short as possible. If the distance between the audio control room and the speakers is too far, the power amplifier can be placed near the speakers if necessary. Secondly, the material of the speaker wire also affects the sound quality. In terms of sound engineering, a special speaker wire made of oxygen-free copper can be used. The higher its purity, the better the sound quality. When selecting speaker wires, try to choose oxygen-free copper wires with larger cross-sectional area and more strands. Usually high-quality products are very soft in texture, which is also a way to identify the quality of speaker wires. In electro-acoustic engineering, because the speaker wires are long, it has a great impact on the sound quality. When there is no condition to use oxygen-free copper speaker wires, you should try to choose high-quality copper with larger cross-sectional area and more strands. Wire. The signal voltage sent by the power amplifier to the speaker is tens of volts, and the instantaneous current can be as high as nearly a hundred amperes, so there is no need to use shielding measures for the speaker cable. It is impossible to use a single-core audio coaxial cable to replace the speaker line, because the shielding layer of this cable is made of iron material, and the internal resistance of iron is relatively large, so it is not easy to use for high-power signal of the speaker cable. transmission. It is required that the line resistance of the connecting line should not exceed the internal resistance of the professional amplifier. Therefore, for ultra-long speaker cables, if the resistance exceeds 0.02 ohms, thicker copper wires should be used instead, which can not only reduce the wire consumption of the power amplifier system, but also ensure the sound quality.

What are the quality requirements of the wire harness for electronic wire connectors? The electronic connector should meet the specifications, add the contact surface of the wire as much as possible, and avoid the hook connector implementation method connecting through the terminal. First, the multiple strands should be fastened, and the filament should not be exposed. The USB Cable wire must be bent into a loop. Placed on the terminal, the washer screw on the pad, the cover should be tightened, the connection method The large cross-section wire and the aluminum connection core wire are easy to use welding or crimping methods. When the crimping method can be used, the conductive paste can be applied. The copper-aluminum wire transition joint is easy to use the copper-aluminum transition joint; it can also be connected with copper and aluminum. Put a thin layer of copper or tin on the copper wire lug and connect with aluminum wire. This implementation can reduce contact resistance. The position of the electronic wire connectors is staggered. The connectors of each phase line should be intertwined. The outside of the Micro USB cable connector should be wrapped with a large cross-sectional area of black rubber tape. The interior should be coated with yellow wax cloth or yellow wax cloth to improve thermal insulation. It can't exist in the electrical structure, luckily you have to take precautions and pay attention to all the above steps to avoid a fire accident due to poor electrical connections. Oxidation at the junction of conductors In the ecological environment of humid and corrosive air, the oxide layer is simply formed on the conductor, and the oxidized copper wire will appear on the copper. The conductivity of aluminum oxide is more likely to be built into the aluminum wire. In the workshop, the Wire Harness wire is corroded by acid air for a long time, and the conductor forms an oxide layer on the appearance, which leads to an increase in contact resistance. When the power is turned on, high temperature occurs.

If a Micro USB wire harness processing factory is a manufacturer of connecting wires, people can choose some better methods. For this part, the way people pass through their own cables, cables, electronic wires, wires, and electronic wires must be To achieve very good results, when people are planning this aspect, they can also do some relevant understanding, and this approach makes many people feel that the effect is very good, but in When purchasing or using, you must understand the type of interface here, as long as you can achieve good results and let yourself better understand this aspect, as long as this ability makes people feel that it is Very nice. First, a type of interface used in the cable is the USB Cable data cable. This type of cable is widely used, because for many people, the cable, electronic wire, wire, electronic wire The control of this part of them must be able to achieve very good results sometimes, and once the problem is really completed, people will obviously feel that it is not so good, which is to make people feel that the effect is not good. So good is an important reason, and it also has a very good effect at the same time, this aspect is a very important aspect. Second, when cables, electronic wires, wires, electronic wires, and connecting wires are in use, a very good one is the HDMI type in use, which makes many people feel that the effect is still good. , when these aspects are used, it is when the computer is directly connected to a TV or a projector. Some of them are definitely a very necessary type, and at the same time, a very good effect is achieved because of them. . Third, the audio connector's connecting line, flat cable, electronic wire, wire, electronic wire and VGA interface and the type of DVI interface used, this part is still very good when it is used, and it also brings people This is the feeling brought by a good product, which makes people's life more convenient and convenient.

The quality of the USB Cable harness material directly affects the quality of the harness, and the choice of harness material is related to the quality and service life of the harness. Therefore, in the selection of wire harness products, we must not be greedy for cheapness. The cheap wire harness products may be selected from inferior wire harness materials. How to distinguish the quality of the wire harness? Understand the material of the harness. The following are the materials for the wire harness selection. The wire harness is generally composed of wires, insulating sheaths, terminals and wrapping materials. As long as you understand these materials, you can easily distinguish the quality of the wire harness. The choice of wire harness wire material: According to the application environment different, select the corresponding wire material. Selection of insulating sheath materials: The commonly used materials for sheath materials (plastic parts) are PA6, PA66, ABS, PBT, pp, etc. According to the actual situation, flame retardant or reinforcing materials can be added to the plastic to achieve the purpose of strengthening or flame retardant, such as adding glass fiber reinforcement. and bronze (brass is slightly less hard than bronze). Among them, brass accounts for a larger proportion. In addition, different coatings can be selected according to different needs, and the choice of wrapping materials: the wire harness wrapping can play the role of wear resistance, flame retardant, anti-corrosion, prevent disturbance, reduce noise, and beautify the appearance, generally according to the working environment and space size. Choose dressing material. In the selection of dressing materials, there are generally tapes, corrugated pipes, PVC pipes, etc. We are a professional OEM cable assembly manufacturer, specializing in the production of MINI USB, etc. We have multiple sets of molds to support your product requirements.

When it comes to sweaters, the key words that everyone think of must be street, youth, vitality, sunshine, etc. Because of this, it is the love of many fashionable people. With both the characteristics of fashion and warmth, this autumn is destined to be indispensable. About the style of the sweater There are actually quite a few styles of sweaters. The most common ones include round neck sweaters, hooded sweaters, cardigan sweaters and lapel sweaters. Each has its own characteristics. I believe there is always one that suits you. 1. Round neck sweater This is the most common type of sweater we see. The round neck sweater is relatively simple as a whole. It feels very refreshing and clean, and it can wear a feeling of a big boy next door. There are more combinations, but the simpler the better. The white crew-neck sweater matches the white shoes, the blue baseball cap matches the trousers, and a satchel is the finishing touch. Walking on the street in this outfit, who can resist taking a second look! If you want more layers, stacking is also a very good choice. Canvas shoes paired with khaki pants, blue round neck sweater and white T inside form a contrasting color, and then add some accessories to embellish it, a proper street fashion man. If you want to give people a feeling of wanting to be close, don`t miss out on light-colored outfits 2. Men's Sports Hoodie Hooded sweaters are also a very common type of sweater. If a round neck sweater feels like a big boy next door, then a hooded sweater feels like a cool boy with a hint of rebellion, and The built-in hat also has a practical function of windproof and rain protection. As the so-called hat is worn, no one loves it. The matching of hooded sweaters is more casual, and jeans, overalls and slacks are all good partners. 3. Cardigan sweater Different from the previous two types of sweaters, cardigan sweaters are relatively unpopular. The biggest feature is the zipper in the middle, which feels more like a jacket. It is definitely a good choice to match with a sporty style. 4. Lapel sweater The lapel sweater is also a relatively small type of sweater. It may be because of the collar that it brings a bit of maturity in it. Therefore, it is necessary to pay attention to the choice of the material of the clothes and the matching, otherwise one will not pay attention. Become a greasy old cadre. The material should be made of cotton as much as possible. If you match it, you can choose to layer it, which can not only keep you warm, but also weaken the sense of maturity. In addition, we have Men's Polo Shirt on sale, selected high-quality fabrics, comfortable and soft to wear. It can be worn on many occasions, and it is fashionable and versatile. We are a clothing manufacturer specializing in sports goods, including sportswear focusing on equestrian wear, Men Jodhpurs, sports wear, more convenient and comfortable. Our garments are very stretchy and are not afraid of being stretched when exercising.

There are three types of mobile phone charger interfaces commonly used in the market: the USB Type C interface and Micro USB interface used by Android products and the Lightning interface commonly used by Apple products. The Micro USB interface is a reduced version of the USB 2.0 standard. For foolproof and blind insertion, it can only be inserted on one side and supports the data exchange function. Only compatible with USB1.1 and USB 2.0, the transfer speed is very slow. Micro USB data cable is currently more commonly used in mobile phones on the market. Most Android mobile phones use Micro USB data cable to charge and transmit data. The USB Type C interface is compatible with the USB3.1 standard, and the plug can be inserted in both directions, and the transmission speed is fast. Now the interface of Android phones is gradually changing from Micro USB to Type C adapter cable (data cable) Type C adapter cable will also become the main force of Android phones in the future The Lightning interface is a special interface designed by Apple for their company's products. Starting with the iPhone 5, almost all new iPhones and new iPads are equipped with Lightning data interfaces. The Lightning interface has 8 contacts on both sides, and like the USB Type C interface, it also has the feature that it can be plugged in both sides. We are a manufacturer of various data cables and adapter cables with years of experience in professional development, design, manufacture and sales. The main products are USB Cable and so on. The products are mainly used in high-definition 3D home theater/smart home appliances/smart phone digital/tablet PC/automobile industry and intelligent engineering integrated wiring, etc. The company will continue to innovate around the needs of customers, openly cooperate with partners, and devote itself to providing customers with systematic solutions, products and services, and creating maximum value for customers.

Apple officially released the new iPad Pro. The machine cancels the 3.5mm headphone jack and Lightning interface together, and uses the USB Type-C interface instead. Many people are madly calling for Apple's move, because the Type-C interface can not only charge, but also transmit data, and also supports data and audio output. As such, the new iPad Pro comes with a USB Type-C to 3.5mm headphone jack converter, which is available in retail versions. This cable has a Type-C interface at one end and a 3.5mm audio socket at the other end with an audio chip built in, so this adapter cable can be regarded as a complete USB sound card. So many people have opened their minds. Now many popular Android phones are equipped with Type-C interfaces. Can Apple's Type-C audio adapters be used? Recently, I Love Audio Network conducted an interesting test. They tested the Nut Pro 2, Xiaomi Mi 5, Meizu E3, OnePlus 6T, Sony Xperia XZP, Xiaomi Mi 8, Meizu 16th Plus, Huawei Mate 9, and Honor. 8. Meizu Pro 6 Plus. The result of the test is: these Snapdragon platform mobile phones and Kirin platform mobile phones all support the Apple Type-C to 3.5mm adapter cable. Next, they tested the adapter cable on the 2018 MacBook and 2017 iMac, and the results also worked normally. Friends in need can try this line. It should be noted that this data cable needs to be set up to connect the iPhone 6 Plus, and the USB should be set as the digital audio output. Other problems are not big. We focus on DC connector, DC jack, audio jack and OEM molding cable assembly like DC cable, aux cable, USB A cable, USB B cable, micro USB cable, mini USB cable, USB type C cable and OEM electronic wire harness, plastic part, metal part and other. Our product are widely used for monitor, router, computer, mobile phone, adapter, earphone, solar product, Led and others.

What procedures should be paid attention to in electronic custom wiring harness processing? Electronic wiring harness processing presents problems such as wire harness broken cores, terminal wire terminals simply falling off or electronic wire harness virtual welding and wire harness connectors not being threaded in place. Some of these problems are caused by human error, some are wire harness processing equipment problems, and some are Wire harness raw material problems, these problems will affect the quality of the wire harness. 1. The terminal of the terminal wire is dropped. This situation is just the opposite of the situation of the third party above. The terminal machine is adjusted too loosely when the machine is adjusted, so that the terminal cannot tightly wrap the wire harness. 2. The wiring harness connector is not pierced in place. This situation is mainly manifested in the wiring harness assembly process. The electric vehicle wiring harness is not in place when it is inserted into the connector housing. Under normal conditions, there will be a "click" when it is inserted in place. To ensure that it is in place , You also need to do a pullback action, that is, hold the connector in one hand and pull the wire tightly in the other hand, be careful not to use too much force to avoid breaking the wire harness. 3. The electronic wire harness is soldered. When the wire harness is welded, the wire core cannot be tinned, or when the contact surface of the two wire cores is too small, there will be a virtual welding phenomenon. Since the welding place needs to be covered with an insulating sleeve, the appearance is not visible. If it does not come out, some problems can be found during the quality inspection process. If this kind of wiring harness is installed on the equipment, it will simply fail. 4. There are three reasons for the broken wire core of the electronic wiring harness: First, the quality of the wire harness raw material cable is not good enough, the flexibility is not good, or the wire diameter is lacking; The third is that when the wire harness is crimped to the terminal, the machine is adjusted too tightly, and the lower pressure of the blade is too large, resulting in the cracking of the core wire. We focus on DC connector, DC jack, audio jack and OEM molding cable assembly like DC cable, aux cable, USB A cable, USB B cable, micro USB cable, mini USB cable, USB type C cable and OEM electronic wire harness, plastic part, metal part and other. Our product are widely used for monitor, router, computer, mobile phone, adapter, earphone, solar product, Led and others.

The full name of Type-C is the USB Type-C interface, which is a new form of USB interface. The USB Type-C interface is 8.3mm wide and 2.5mm thick, while the Micro USB interface is 7.4mm wide and 2.35mm thick. Type-C is slightly larger than the Micro USB interface and thinner and thinner than the traditional USB. In addition to the slimness and thinness of USB Type-C, other advantages are more worthy of attention. If it can be inserted on both sides, it is thin and durable, and can withstand tens of thousands of repeated insertion and removal. The transmission speed can reach 10Gbps, and the power supply capacity can reach up to 100W. audio etc. The method of changing the USB Type-C data line to the OTG data line has been introduced before. In one sentence, the CC pin is connected to the ground with a pull-down resistor of about 5.1K, and the operation mode is converted, so that the Vbus pin can be used externally to the U disk, mouse, keyboard, etc. powered by. The mobile phone can directly read the files in the U disk, and can also copy the files in the mobile phone to the U disk, without the need to transfer data through the computer, it is very suitable for use when going out. Detailed definition of USB Type-C interface, teach you to change Type-C data cable to OTG data cable I just said that the USB Type-C data cable can not only charge and transmit data, but also transmit audio and video. Many Android phones not only replace the traditional Micro USB with the Type-C interface, but also cancel the 3.5mm headphone jack. For such a mobile phone, you can only use the Type-C to 3.5mm headphone conversion cable. After studying the definition of the Type-C interface and related materials, it was found that the pins corresponding to the Type-C output audio and the received microphone signal are as shown in the figure below. . Pins 6, 7, and 8 correspond to the right channel, left channel, and microphone, and pin 1 corresponds to the GND of the headset. The earphones used on mobile phones are all three sections and four sections, with four cables, namely GND (ground), Mic (microphone microphone), L (headphone left channel), and R (headphone right channel). Using a multimeter to measure a variety of headphones, most of them are the first connection method, only Nokia is the second connection method. This makes it clear that the pins of Type-C are connected to the earphone microphone, the left and right channels of the earphone, and you can make a USB Type-C to 3.5mm earphone adapter cable. Experience the fun of DIY and enjoy the joy of success. Note that the random Type-C data cable of the mobile phone is basically missing some pins that have shrunk, and check whether the required pins are in good condition before the transformation. In addition, the USB Type-C plug has many pins, which are very dense and difficult to solder by hand. Please do your best.

The longest part of the data cable is also the most critical part, which is the wire. The wire consists of an inner core, a central shield, and an outer jacket, each of which deserves a little consideration. Inner core (1) Raw materials The data cables on the market mainly include copper wire, iron core copper, iron core galvanized and iron core. The copper wire charging speed is the fastest and the iron core is the slowest. It can pass a maximum current of 2A during the current transmission process, and it is not easy to present the risk of heat generation. It is the most ideal inner core material. (2) Quantity "Charging for five minutes, talking for two hours" is the demand of many people, and the number of inner cores can also speed up the charging speed accordingly. Now there are mainly 8-core, 10-core, and 12-core options on the market. The more the number, the faster the charging, and the price will rise accordingly. You can choose on-demand in combination with charging speed and price. Shield The shielding layer is to wrap the wire core with a layer of aluminum foil or metal woven mesh outside the inner core, which can prevent the risks of current mutual channeling and short circuit. On the market, there are only one type of shielding layer and two types of shielding layers used together, which can better ensure the charging effect and the price will be more expensive. Quilt The outer quilt is the outermost layer of the data cable, and its hardness, strength, elasticity and other properties directly affect the feeling of use. At present, there are mainly three kinds of jackets: PVC, TPU and braided lines, each with its own advantages and disadvantages, which needs to be selected according to preference. (1) PVC raw materials Polyvinyl chloride, referred to as PVC in English, is a relatively low-cost polymer chemical material. Due to the addition of many additives in the artificial synthesis process, it has a relatively heavy taste in the early use. The surface is lubricated but relatively hard and not very resistant to bending. Advantages: smooth appearance, comfortable touch Defects:There is an odor when it is first received, and it is also easy to burst and break. I don't really advocate choosing such a quilt. (2) TPE raw materials TPE is a thermoplastic elastomer material with good thermoplasticity, elasticity and softness. Compared with PVC material, it is more non-toxic and tasteless. Many original lines are also made of this raw material. It can be said that data lines basically need such raw materials. Advantages: good thermoplasticity, soft touch, high softness, non-toxic and tasteless, not easy to break. Defects: The service life is not long, and it is easy to explode and yellow. (3) Weaving line The weaving line is generally woven with nylon, and a layer of nylon is woven on the outer quilt of TPE. The abrasion resistance and tensile strength are significantly enhanced, and the raw materials of PVC and TPE are significantly more anti-fouling, and the service life is increased. Advantages: long service life, strong anti-stain, anti-pull, anti-break ability. Since it is not made of plastic, it is not easy to show the phenomenon of folding and winding. Defects: Due to an extra layer of outer quilt, if the core selection is not good, it will simply show the phenomenon of charging and heating, which is relatively risky.

The data cable is a necessary component to connect the hard disk and the motherboard, and it is usually included when purchasing the motherboard. Each data line can only connect two IDE devices (such as CD-ROM, hard disk, recorder, etc.). But how much do you know about the basic types of data lines, let's take a look. COM interface COM interface is also called serial port. Most motherboards in the past provided two COM ports, COM1 and COM2. The role of the COM interface is to connect devices such as a serial mouse and an external Modem. The 1/O address of the COM1 interface is 03F8h-03FFh, and the interrupt number is IRQ4; the 1O address of the COM2 interface is O2F8h-O2Fh, and the interrupt number is IRQ3. Therefore, the COM2 interface has priority over the response of the COM1 interface. Later, serial devices such as mice adopted the PS2 interface and the currently popular USB interface, and external devices based on serial ports are rare. USB interface The full name of USB is Universal Serial Bus, which means "Universal Serial Bus" in Chinese. USB was jointly proposed by Intel, Compaq, IBM, Microsoft and other companies at the end of 1994. USB supports hot-plug, and its plug-and-play advantage makes it the most important interface method for computers. The USB interface has 4 pins, which are the USB power supply (usually 5V), the USB data line +, the USB data line and the ground line. USB has two specifications, namely USBI.1 and USB2.0. The transfer rate of the high-speed mode of USBI.1 is 12Mbit/s, and the transfer rate of the low-speed mode is 1.5Mbit/s, 1Mb/s=8 Mbit/s, and 12 Mbit/s=l .5 MB/s. The USB2.0 specification is evolved from the USBI.1 specification. Its transmission rate reaches 480Mbit/s, which is converted into MB to 60MB/s, which is enough to meet the rate requirements of most peripherals. The Enhanced Host Controller Interface (EHCI) in USB2.0 defines a framework compatible with USB1.1, which can drive USB.1 devices with USB2.0 drivers. That is to say, all devices that support USB1.1 can be used directly on the USB2.0 interface without worrying about compatibility issues, and accessories such as USB cables and plugs can also be used directly. The USB2.0 standard further increases the interface rate to 480Mbit/s, which greatly shortens the transmission time of video and audio files in LCD color TVs. Type-C interface Type-c is an epoch-making interface type that can be applied to both PCs (master devices) and external devices (slave devices, such as mobile phones). Micro-USB interface Micro-USB is a USB2.0 standard interface, the next version of Mini-USB. Its features are as follows: Micro-USB connector is smaller than standard USB and Mini-USB connector, saving space; with up to 10,000 times of plugging life and strength; blind-mate structure design; compatible with USB1.1 (low speed: 1.5Mbit/s, full speed: 12Mbit/s) and USB2.0 (High Speed: 180 Mbit/s); simultaneously provide data transfer and charging.

As the connector between the latest electronic devices or between the electronic device and the power supply, the Type-C data cable is very important. The choice of material for the cable is very important. If you use a low-quality data cable, it will lead to prolonged charging time, unstable data transmission, and disconnection. Such hidden dangers may even lead to the scrapping or explosion of electronic equipment. The choice of data cable material determines the service life and safety of the data cable. What are the advantages and disadvantages of data cables of different materials? PVC data cable Polyvinyl chloride, abbreviated as PVC (Polyvinylchloride), is the initiator of vinyl chloride monomer (VCM) in initiators such as peroxides and azo compounds; or free radical polymerization under the action of photothermal polymerization polymers. mechanism. Advantages of PVC data cable: 1. Low cost, good insulation and good weather resistance; 2. The price of PVC data cable is relatively cheap. TPE data cable TPE material is a kind of rubber material with high elasticity, high strength and high resilience, and has the characteristics of injection molding. Advantages of TPE data cable: 1. Excellent processing performance, excellent colorability, soft hand feeling, weather resistance, fatigue resistance and temperature resistance; 2. Safe and non-toxic, no peculiar smell, and will not cause any irritation to human skin; 3. Can be recycled to reduce costs. Nylon braided data cable Nylon has the characteristics of flame retardant, high strength, wear resistance, electrical insulation, etc. Its plastic material is translucent, white or black crystalline polymer with plasticity. Nylon has good strength and abrasion resistance. The advantages of nylon braided data cable: 1. Increase the appearance and pull-out strength of the data cable; 2. No threading phenomenon, soft, curved and fit, good resilience, not easy to tangle and wrinkle; 3. Good durability, not easy to deform.

What is an OTG data cable? This is a question often asked by many people who do not know what an otg cable is. Then what does an otg data cable look like? Let's follow the otg data cable manufacturers to find out. What is the OTG data cable: The OTG data cable is mainly used for the connection between various devices or mobile devices, for data exchange, the mobile phone can be used as a computer, or it can be connected to a U disk, a USB network card, etc. The OTG function is to realize that the mobile phone can be connected to USB devices such as U disk. OTG data line function: It is to realize data transfer between mobile devices without a computer. Compared with the one-line connection of two mobile devices, the devices can be directly connected through the OTG line for data transmission and printing operations. No need to bring a memory card or computer to transfer. The most common is that the mobile phone is connected to a USB device such as a U disk through an OTG cable, thereby expanding the functions of the mobile device. The OTG data cable can be used for reverse charging of the mobile phone. When the mobile phone is connected to another electronic device with a data cable, if it is connected to a computer, it will automatically start charging, but when it is connected to other mobile electronic devices, no operation can be performed. But if we turn on the OTG function of the mobile phone, when we connect other small mobile devices with a data cable, it will in turn charge other devices, and if necessary, we can respond to emergency needs. OTG data cable connection for file editing, when our mobile phone is plugged into the mobile phone U disk, we can generally only transfer the files in the mobile phone to the mobile phone U disk, but under the premise of enabling the mobile phone OTG function, we will You can perform detailed operations such as copying, deleting, renaming, editing, etc. on the files in the U disk. The OTG data cable is connected to the mouse and keyboard. In the use of the mobile phone, we can also connect the mouse through the OTG function of the mobile phone, and then use the mouse to operate the mobile phone, and also connect the keyboard for text input and other operations. Classification of OTG data lines: Generally, there are two types of OTG data lines, one that needs to be connected to the power supply, and the other that does not need to be connected to the power supply. But their functions are the same, generally used as external devices connected to USB, such as printers, cameras and other devices. We focus on DC connector, DC jack, audio jack and OEM molding cable assembly like DC cable, aux cable, USB A cable, USB B cable, micro USB cable, mini USB cable, USB type C cable and OEM electronic wire harness, plastic part, metal part and other.
