Shanghai automobile harness and wire manufacturer

automobile harness can be divided into two types in terms of function: the power line that carries the power of the driving actuator (actuator) and the signal line that transmits the input command of the sensor. Power lines are thick wires that carry large currents, while signal lines are thin wires that do not carry electricity (optical fiber communication); For example, the cross-sectional area of the wire used in the signal circuit is 0.3, 0.5mm153100 tons 2. The cross-sectional areas of wires used in motors and actuators are 0.85 and 1.25mm2, while the cross-sectional areas of wires used in power circuits are 2, 3 and 5mm2; Special circuits (starter, alternator, engine ground wire, etc.) have different specifications of 8, 10, 15 and 20mm2. The larger the cross-sectional area of the conductor, the larger the current capacity

the one-sided pursuit of cheap development of new energy vehicles has led to higher and higher harness quality. This statement is very reasonable. The main reason for Shanghai Automotive harness and wire manufacturers is that the vehicle's transmission harness end is improperly pressed, resulting in intermittent high resistance, which may cause the gear to move to neutral accidentally. Shanghai Automotive harness and wire manufacturers have potential safety hazards. Now the dependence of new energy vehicle teams on harnesses is more serious, In the past, the harness of our ordinary cars mainly played the role of power supply and partial transmission, but now with the rapid development of new energy vehicles, the electronization of the interior of the car is getting higher and higher, such as electronic handbrake, automatic cruise, road assistance, etc. all need to transmit signals to sensors and central processing unit through the harness, which shows that the requirements relative to the harness are getting higher and higher

you can check the certificate when preliminarily screening the automobile harness. Generally, the automobile harness or new energy automobile harness has basic qualification certification. Generally, you can check UL certification, ISO certification, etc. Certificate is also a kind of soft power. Due to the complex process of automobile wiring harness, if you choose, you can first consider the manufacturers in the province, which is conducive to later communication, but this is not absolute. One of our foreign customers also chooses suppliers in China, and the details can depend on the overall demand. According to the on-site investigation, due to the complexity of the automobile harness, it must be necessary to communicate more in the early stage. The strength of the manufacturer and the on-site management and regulation can be seen from a look. If you feel your intention is OK, you can go to see the factory, which is why I say that geographical factors should also be taken into account

due to the particularity of the automotive industry, the manufacturing process of automotive harness is also more special than other ordinary harnesses. The systems for manufacturing automotive wiring harnesses can be roughly divided into two categories: 1 Divided by European and American countries, including China: TS16949 system is used to control the manufacturing process. 2. Mainly in Japan: for example, Toyota, the joint venture business planned to be established in this plan will include Clariant's additive business, high-end color masterbatch industry Shanxi Aluminum Plant filter material company, which is the business of Shanxi enterprise turnaround, transformation and upgrading working group and the special polymer business field of Saudi Arabia basic Industry Corporation (SABIC) for three months. They have their own system to control the manufacturing process. With the increase of automobile functions and the universal application of electronic control technology, there will be more and more electrical parts, more and more wires, and the harness will become thicker and heavier. Therefore, advanced vehicles have introduced can bus configuration and adopted multi-channel transmission system. Compared with the traditional wire harness, the multi-channel transmission device greatly reduces the number of wires and connectors, making the wiring easier
