The connection of the wire harness is the key to realize the soft connection or hard connection of the wire harness, conversion, cutting, and wiring. Most of the wiring harnesses are connected between the wiring harness and the metal terminals. The steps are basically peeling, wire clipping, pressing, sealing, welding and other processes. How to improve the comprehensive performance design of industrial connectors or automotive electronic wiring harnesses has become the focus of attention, and sealing or plastic sealing is the most commonly used way of insulation isolation.
