Terminal harness production inspection standards

What is a terminal harness? Terminal harness is a harness with connectors. When a relatively long connection distance is reached by welding with wires, we call the wires with connectors at one or several ends terminal harnesses. There are many types of terminal harnesses, such as aviation head wires for security monitoring, waterproof wires, GPS multifunctional power cords for vehicle terminal wires, DVD power signal cords, etc., O-type terminal wires for in-machine connecting wires, DuPont 2.0, etc. The raw materials of terminal harnesses mainly include tubular terminals, disc terminals, pin terminals, plug-in terminals, etc.

The production process of wiring harness is as follows: 1: Task distribution 2: Prepare tools 3: Complete production 4: Thread heat shrinkable number tube 5: Insert waterproof plug 6: Crimp terminal 7: Thread waterproof plug 8: Strip wire and wear heat shrinkable sheath 9: Inspection 10: The packaging terminal consists of three parts: plug-in area, transition area and crimp area. The plug-in area is the part where the terminal is plugged into the other half of the connecting terminal. The crimping area is the only part designed to be affected by the crimping process, and the crimping area is clamped using the termination equipment recommended by the connector manufacturer. The inspection of the wiring harness that can be firmly connected to the wire generally starts from the front to the back, from the front section to the back end, and then from the top to the tail end. Observe whether the cable insulation layer is intact, whether there are scratches, damage and exposed wires, and whether the end bullet piece is deformed and exposed copper, etc. Secondly, check whether the conductor meets the specification requirements, whether the conductor copper is covered with Ruth, check the riveting shape and riveting shape, whether the front side tail of the terminal is deformed, and whether the material tape is too long, etc.
