The general process of wire harness machining is briefly introduced

Wiring harness is mainly used to connect various electrical equipment in the circuit inside a wiring component, is composed of terminal, insulation wrapping material, insulation sheath and wire. Wiring harnesses are basically everywhere in life, such as the computer host will have wiring harnesses. So what is the general processing process of the wire harness before it is used?

The first is the acceptance of incoming materials, which can be tested by relevant instruments for environmental protection, harness processing manufacturers after the test to see if it is in line with ROHS standards, in the incoming materials can not contain lead and mercury and other harmful substances. Then is the wire sending equipment, mainly the need to process the wiring harness on the transfer wire rack above, be careful not to scratch the surface of the wire. Secondly, the wire is sent, and the wire is placed on the wire feeder for fixing. After that is the cutting line, is the use of the cutting machine to cut the line to the appropriate length, when doing this work, pay special attention to, can not cut the surface of the wire, can not cut the copper wire, the length of the peeling error is best not to exceed 1 mm. The second is the peeling of the wire, according to the requirements of the standard, the insulation skin of the corresponding length of the wire at the junction is peeled. The error should also not exceed 1 mm. In addition, the twisted wire is arranged and twisted at the joint, the surface of the wire cannot be scratched, the copper wire must be twisted tightly, and the situation of loose wire cannot be used. After Z is the connection terminal, connect the conductor at the junction and the plug terminal, pay attention to the width and height requirements.

When these processes are completed, the wiring harness processing is basically completed, and only the assembly process after Z is left. For example, there is the assembly of products, the assembly of the shell of the plastic plug must meet the torque required by the product. The second is the conduction test, the use of instruments for wiring harness conduction test, do not appear open circuit, poor contact and insulation and other phenomena. Z is the packaging light sealing box, the use of tape to wire harness finished products into the carton, the seal should be smooth, packaging tape when the carton, can not fall off the situation.
