Electrical wiring harness production quality points
1 CD line : Check the wires specifications are correct ; sizes to meet the requirements ; incision must be flush , can not scratch the wire , wire -free dirt and so on.
2 peel the skin : checking whether stripping mouth flush inalienable wound wire , wire and other grouping , stripping dimensions are correct.
3 marshalling treatment: trim size is correct, whether flush trimming , pruning grouping can not hurt to the core line.
4 stripping endothelial : checking whether stripping mouth flush ; stripping dimensions are correct ; whether the injury stripping wire , broken wire ; half stripping insulation can not fall off.
5 sets shrink tube: check shrink tube sizes , models are correct.
6 preliminary solder : Check furnace temperature is correct ; whether the former preparatory solder copper wire collated , whether bifurcation , bending, discounts and other phenomena ; whether bifurcation after preliminary solder wire , bulk wire arrhythmia and burn insulation and so on.
7 Solder : Check the soldering iron temperature is correct ; non- burn insulation , tin point should be smooth, Wuxi tip not false welding , Weld.
8 Crimping : Confirm terminals , wire specifications are correct ; Crimping whether the bell, tilt, insulation and exposed wires are too long or too short.
9 terminal is inserted : Check connectors, terminal model is correct ; terminals for damage or deformation ; terminal of a seamless plug, plug the wrong insertion is not in place and so on.
10 Cable Crimp : Check connector models are correct ; cable in the correct orientation ; core cable is damaged, exposed copper , scald ; crimp is in place .
11 blown shrink tube: shrink tube contraction is good, can not burn the insulation .
12 Assembly Housing : Housing is installed wrong , with or without scratches, burrs and other undesirable , a seamless installation parts , tighten the screws with or without hair , oxidation, discoloration, loosening bad , no bad fit after assembly ; such as the direction of the shell is , and then it must be in accordance with the requirements of the assembly .
