Problems solved by technology

This is a big problem that needs to be solved. How to arrange a large number of wiring harnesses more effectively and rationally in a limited car space, so that the automotive wiring harness can play a greater role, has become a problem faced by the automobile manufacturing industry. The common automotive wiring harness lacks effective Heat insulation and flame retardant structure, especially when open flames are generated, are likely to cause overall safety accidents; many automotive wiring harnesses have relatively weak anti-aging protection structures, and are prone to rapid corrosion due to sewage or internal bacteria. At the same time, the use of automotive electronic wiring harnesses During the process, the wire harness is often affected by external forces such as stretching, etc., and is also often affected by temperature. Long-term wear and tear makes the electronic wire harness more likely to be damaged or broken, causing the wire cores to be exposed and leakage occurs, which not only affects the use, but also It will pose a certain threat to the safety of people and buildings
