Wire Harness Processing Factory Big Reveal! Three steps to understand the wiring harness processing process

Wiring harness in the electronic and electrical and general machinery and equipment industries play a role in the bridge, mainly used in the circuit to connect the various electrical equipment inside a wiring component, is composed of terminals, insulation wrapping material, insulation sheath and wire. Wiring harnesses are basically everywhere in life, such as computer mainframes will be inside the wiring harness processing plant wiring harness. Can be stable connection of various electronic and electrical equipment, to achieve the accuracy of each interface, depends on the wiring harness processing process is able to do every step of the strict control, no error.

So before the use of wire harnesses, wire harness processing plant in general what is the processing process? Step The acceptance of incoming materials through the relevant instruments to carry out environmental protection tests, 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. The second step of the wire feeding equipment 1, the main need to process the wire harness in the middle of the feeder above, be careful not to scratch the surface of the wire. 2, followed by the wire feeder, the wire to the feeder above the fixed. 3, after that is the cut wire, is the use of wire cutting machine to cut the wire to the right length. Precautions: (1) When doing this work, special attention should be paid to not cut the surface of the wire, and not to cut the copper wire, stripping the length of the error is better not more than 1 millimeter. (2) again is the stripping of the wire, according to the standard requirements of the joints of the wire corresponding to the length of the insulation of the outer skin stripped. The same error should not exceed 1 millimeter. (3) In addition is the twisted wire, in the joints of the place to organize and twisted wire, can not scratch the surface of the wire, be sure to twist the copper wire to tighten, do not use the situation of loose wire. (4) Finally is to connect the terminals, the connector conductor and plug terminals for connection, pay attention to the width and height requirements. Step 3 assembly process when these processes are completed, the wiring harness processing is basically complete, only the final assembly process. For example, there are product assembly, assembly of plastic plug shell, must meet the product requirements of the torque. Then there is the test of conduction, the use of instruments for the harness conduction test, do not appear disconnection, poor contact and insulation and other phenomena. Finally is the packaging light sealing, the use of tape will be the finished wire harness into the carton, sealing to be flat, packing tape when the tight package carton, can not appear off the case.
