How to detect the quality of electronic wiring harness

Electronic harness is widely used in electronic engineering. Electronic harness is mainly used for electronic control input and output. The quality of the electronic wiring harness is very important. The quality here not only refers to the surface quality, but also the quality of the internal wire, terminal, solder and shell. When harness of electronic wire of choose and buy, must undertake strict inspection to its quality, unqualified harness of electronic wire is not conducive to use. So how to detect the quality of electronic wiring harness? The following electronic wiring harness manufacturers to answer for you:

 

1. Grouping treatment: check whether the trimming is neat and the size is correct. When trimming and grouping, the core wires cannot be drawn.

2, peeling: check whether the peeling mouth is neat, peeling the size is correct, can not peel the cord and core wire.

 

3, cut line: check whether the size of the wire is in line with the relevant requirements, the model is correct. The cut must be neat, can not scratch the wire, and the wire can not have dirty situation.

 

4, peel the endothelium: check whether the peeling mouth is neat, the size of the peeling is correct, whether the core wire is peeled, whether the copper wire is peeled; The insulators must not come off during half-stripping.

 

5, sleeve shrinkage tube: carefully check the type and size of the shrinkage tube is correct.

 

6, prepare solder: check whether the temperature of the tin furnace is right; Before preparing the solder, the electronic wire harness should arrange the core wire and copper wire, and check whether there is bending, bifurcation and discount.

7, solder: check whether the temperature of the electric iron is correct; The insulation skin can not be scalded, tin point to smooth, no tin tip, can not virtual welding and false welding.

 

8, terminal pressing: check the specifications of the terminal and wire is correct; Whether the terminal pressing is tilted or lamaxed.

 

9, terminal insertion: check whether the type of terminal and connector is correct; There is no deformation and damage of the terminal; Check whether the terminals are improperly inserted, missed, or improperly inserted.
