The wiring harness is the wiring part that connects the electrical equipment in the circuit, and is generally composed of an insulating sheath, wiring terminals, wires, and insulating wrapping materials. The earliest wiring harness was simply to bundle the wires in the equipment into a bundle with insulating materials. Can facilitate the installation and maintenance of later equipment. After the continuous development of this concept, a safer and more standardized modern wiring harness was born. After reasonable arrangement of modern wiring harnesses, it can be more convenient for later maintenance and replacement, ensuring that electrical equipment can work normally under harsh conditions.
Of course, to ensure the quality of the wiring harness, we also need to vigorously check the production environment. Especially the four processes of wire harness production: wire cutting, stripping and crimping terminals, and tin dipping.
Wire cutting: Use a wire cutting machine to cut the wire to the required length, which requires an automated wire cutting machine. Be careful not to scratch the surface of the wire.
Stripping: Strip the insulation covering of the corresponding length of the wire at the joint according to the requirements of sop. Do not crush the surface during operation, and the stripping length error must not exceed ±1mm.
Crimp terminal: Using willow crimping process, the conductor at the joint and the plug terminal are riveted. It is required that the terminal is not deformed and must meet the tensile force. Requirements of riveting height and width.
Dip tin: Use a constant temperature tin circuit to dip the end of the wire. It is required that the tin is evenly applied, the wire is not scattered, and the tin dip depth meets the requirements.
