Wire harness is basically everywhere in life, for example, there will be wire harness factory in the computer host. Whether a variety of electronic and electrical equipment can be connected stably and each interface can be accurate depends on whether the wiring harness processing process can be strictly checked for each step and make no mistakes.
So before the use of wire harness, what is the general processing process of wire harness processing plant?
The first step is acceptance of incoming materials
This can be tested for environmental protection through relevant instruments. After the test, we will check whether it meets the STANDARD of ROHS. The supplied materials should not contain harmful substances such as lead and mercury.
Step 2 Wire feeding equipment
1, mainly the need to process the wiring harness in the transfer wire frame above, pay attention to can not scratch the surface of the wire.
2, followed by wire feeding, the wire into the wire feeder above the fixed.
3, after is the line cutting, is to use the line cutting machine to cut the line to the appropriate length.
Matters needing attention:
(1) when doing this work, special attention should be paid to not cutting the surface of the wire, nor to cut off the copper wire, and the length error of peeling had better not exceed 1 mm.
(2) Moreover is the stripping of the wire, according to the requirements of the standard to strip the insulation of the corresponding length of the wire at the joint. The error cannot be more than 1 millimeter.
(3) The other is to twist the wire, finish and twist the wire in the joint place, can not scratch the surface of the wire, be sure to twist the copper wire, can not be used to loose the wire.
(4) The last is the connection terminal, connect the conductor and plug terminals at the junction, pay attention to the width and height requirements.
Step 3 Assembly process
When these processes are completed, the wiring harness processing is basically completed, leaving only the final assembly process.
For example, product assembly, assembly of plastic plug shell, must meet the product requirements of torsion.
Furthermore, the conduction test, the use of instruments for wiring harness conduction test, do not appear disconnected, poor contact and insulation and other phenomena.
Finally, the packaging lamp sealing, the use of tape wire harness finished products into the carton, the sealing should be smooth, packaging tape when the carton packing, can not fall off.
