Wire harnesses are used as a bridge connecting the various electrical components of the vehicle to realize the normal connection of various electrical circuits, and more and more content needs to be controlled. There is a saying in the industry that electrical appliances are the most problematic in each segment of the car, and the most problematic component in the electrical appliance is the wiring harness. In view of the many failure modes of automotive wiring harness products, the withdrawal of connector terminals is the most unacceptable. As there are many factors affecting needle withdrawal, it covers all aspects of design, parts production, and wiring harness manufacturing.
