Wiring harnesses are used a lot in the production of some equipment. The purchasing personnel should have a basic understanding of the quality of the wiring harnesses after the processing. On the one hand, the quality of wire harness can be better guaranteed, and on the other hand, some unnecessary losses can be avoided.

1. Judge the quality of wiring harness processing connector, choose the manufacturer to provide the connector with quality assurance, or find the manufacturer to provide one-stop service for connector production and wiring harness processing, or find the manufacturer to provide proofing;

2. Judgment of wire harness processing wire

The wire has a print on it, the print contains all the general information of the wire;

There are many ways to judge the insulation layer material, and different methods to judge the wire material are different.

Wire inspection method, at present the most commonly used conductor is tin copper wire, copper clad steel electrical performance is very poor but the price is very low, can identify with magnets; Professional to measure the resistance, measure the conductor diameter and root number, and conductor ductility;

3. Judgment of wire harness processing quality

Terminal pressing is the core technology of processing.

Forming from the perspective of aesthetic appearance to determine the comparison;

The welding process must be dissected to observe whether the tin spot is full, whether there is no virtual welding, false welding, leakage welding, etc
