As the main body of the automobile circuit network, the automobile wire harness device plays a crucial role. It is like the "nervous system" of the car. Without wire harness, there is no automobile circuit. Wire harness is usually a component that connects the circuit by pressing the contact terminal (connector) made of copper material and the wire cable, and then adding an insulating body or metal shell outside. Wire harness is usually a component that connects the circuit by pressing the contact terminal (connector) made of copper material and the wire cable, and then adding an insulating body or metal shell outside. Wire harness industry chain covers wire cable, connector, processing equipment, wire harness manufacturing and downstream application industry. Its application field is extremely wide. It is not only widely used in the field of automobiles, but also plays a key role in household appliances, computers and communication equipment, various electronic instruments and meters, etc. In particular, in new energy vehicles, the body wire harness connects the entire vehicle body and ensures stable electrical connection between various electronic devices and power systems.
