7 common problems in wire harness processing and their solutions?

In the wiring harness processing we will encounter a variety of problems. Today we have organized a number of common problems in the processing of wire harnesses and their solutions:1. Wear rubber housing terminal pin off rubber housing wear when the terminal pins often fall, so how to solve it? In fact, each time you insert a hole just pull back.

2.Wire tinned wire once tinned, may lead to PVC heat shrinkage. In this case, choose high temperature resistant PVC and control the tinning time not too long.3. Insufficient tension after crimpingIf the tension of the wire harness is not reached, you can choose to look for the reasons from the following aspects:① Whether the crimping range of the terminals and wires is appropriate. ② The material and structural design of the blade. ③Terminal materials, etc. 4. label does not stick If the label does not stick, then we do not directly touch the sticky surface with our hands, first stick on a clean metal, and then one by one on the line.5. How to conduct reliability testing of cable lines generally need to test the swing, lifting load and conduction properties and so on. General swing test conditions: swing frequency, lifting load, the required zui small swing number and other parameters. Load test conditions should include three parameters: the size of the load, the time of loading and the size of the displacement after loading.6. How to test the terminal coating can do the salt spray test of the terminals.7. Dual-voltage terminals how to test tension dual-voltage terminals should be tested for single conductor tension, the test method is the same as a single conductor.
