The development direction of automotive wiring harness


Competition among wire Harness manufacturers is heating up. Product development to a certain period, competitors will also have the scale, strength, integrity of the enterprise to compete. Smaller companies will be eliminated. Wiring harness assembly is more and more concentrated in the technical strength of the enterprise.

Because the automobile wiring harness is different from the general wiring harness, there are some electronic components attached to the automobile wiring harness, such as sensors, thick film circuit mixed assembly, this kind of electronic components technology content is higher, emphasize the technical safety and reliability; Has moved beyond simple, generic assembly. It is reported that a mid-range car has nearly 1,000 connection interfaces, more than 30 microprocessors, hundreds of pAirs of connectors, and the total length of the wires used is 1500m-2000m. With the development of IT technology, the E concept car has put Forward the development direction of automobile network and modularization. The network cluster has been ready to come out, which will make the manufacturing technology of wiring harness appear the second leap. The function of wire harness is expanded from ordinary signal transmission to data transmission.

In addition, the limitation of signal transmission by wire, will use a large number of optical cable, so that the automobile wiring harness manufacturing technology ushered in the third leap, optical cable has the advantages of fast transmission speed, large capacity, small volume, strong confidentiality, good anti-interference and other advantages, will soon become the future automobile data processing and exchange of important preferred material, so that the power and signal distribution system into a new historical stage of development. BMW has already used the cable technology in its D-Class sedan, and Japan has followed suit.

The main development trends of wiring harness technology are as follows:

1. Multi-channel transmission technology: The technology refers to the transmission of multiple signals on a common medium, so that the electronic controller can share information, avoid a single wiring, the application of the new technology, the wiring harness simplified, compact structure, can reduce the weight, but also reduce the cost, because the information is widely shared, rather than simple copy, therefore, for the fault diagnosis, more accurate, Engineering changes are faster and defects are repaired more easily.

2. Multi-station connection technology: the technology refers to the internal connection system that can connect multiple intelligent devices. It can not only share battery energy, reliable grounding, but also share data. Due to the reduction of a large number of contact points, the production cycle, production costs will be significantly reduced.

3. Electronic, electrical integration technology: This technology means that modern automobiles will have a central Electrical box (Bussed Electrical Center) integrating electronics and electricity. In terms of electrical function, it is equivalent to a small substation, which reasonably allocates battery energy to each circuit according to needs. In terms of electronic function, it is just like a small data processing center. Processing and sending various signals. With the increase of car function, the widespread application of electronic control technology, coupled with people's safety, comfort and economic requirements of the car is more and more high, the electrical configuration of the car, the function is more and more, more and more electrical parts, wiring harness connecting each electrical parts is more and more complex, and the car wiring harness will become thicker and heavier. Therefore, the advanced automobile has introduced the CAN bus configuration and adopts the multi-channel transmission system. Compared with the traditional wiring harness, the multichannel transmission device greatly reduces the number of wires and connectors, making the wiring more simple.
