Wire Harness Processing Technology
Feb 10,2022
With the rapid development of automotive technology, the automation and intelligence of cars are gradually increasing. As the nerve network for connecting various electrical devices in cars, the entire vehicle wiring harness is becoming more and more complex, which also puts higher demands on reliability. Meanwhile, the increase in enterprise operating costs also adds pressure to the cost of wiring harnesses.
Generally, when designing the length of the wiring harness, relevant personnel will base it on the actual position of the electrical appliances used in the car, and then carefully design the length of each part of the wiring harness. In addition, there are corresponding holes and zip ties at every position where the wiring harness passes through in the car for fixing. Therefore, the reliability of the wiring harness design is closely related to the reasonable design of the length of the wiring harness. If the wiring harness is designed too long, it will not only waste materials but also occupy more space in the car, which is not conducive to the later work, and it is easy to wear out quickly due to friction with other components during the actual driving of the car, which could lead to faults such as short circuits.
If the design is too short, it will be difficult to control the wiring harness, and it may not be possible to complete the assembly of the wiring harness. If there is a situation where the length is just a little shorter during assembly, some workers may use force to tighten the wiring harness, leaving a large safety hazard, which is not conducive to improving the reliability of the wiring harness design. Therefore, relevant personnel must design the length of the wiring harness reasonably and even prefer slightly redundancy than designing it too short.
For the car's electrical system, the connector and terminal also have a significant impact and are an important component of the wiring harness. Because the car is in a long-term high-speed operation and is subject to erosion from a large amount of oil and dust built up in its mechanical system, the connector and terminal are easily aging, and their positions begin to loosen or even rust, which is very unfavorable for ensuring the normal operation of the car's electrical system and is prone to faults. According to data, the problem of the wiring harness caused by the aging of the connector and terminal, resulting in loosening, accounts for two-thirds of the entire problem of the car's electrical system. Therefore, to improve the reliability of the wiring harness design, it is necessary to improve the reliability of the connector and terminal design.
When assembling the wiring harness, a reasonable process must be selected. Wiring harness assembly is an important part of car production and will have a significant impact on the car's performance. During the assembly of the wiring harness, a reasonable assembly process must be selected to improve efficiency. In addition, research on the assembly process of automotive wiring harnesses should be strengthened, and the assembly process should be continuously improved.
