Common problems and solutions of terminal harness processing

We will encounter various problems in our daily work, especially for newcomers. This is a big problem. Let me explain to youTerminal harness processingCommon problems encountered in the process and solutions.

What problems will we encounter in the processing of terminal harness?

1. When the rubber shell is worn, the terminal will take off the PIN;

2. The wire is stained with tin or connected with tin;

3. The tension after crimping is not up to standard;

4. The label cannot be pasted;

5. How to test the coating of terminals;

6. How to test the tension of the double-voltage terminal;


The solutions to the above problems are as follows:

1. You only need to pull back when you insert a hole each time. Make the snap on the terminal harness and the rubber case snap together. When pulling back, you can feel the resistance obviously, so that there will be no problem of PIN disconnection.

2. Once the wire is coated with tin, it may cause PVC to shrink under heat. In this case, PVC with high temperature resistance should be selected and the time of tin exposure should not be too long. When connecting tin, dip the tin-connected wire again and gently pull the two wires to both sides, so that the tin-connected wire will not continue.

3. If the tension of the harness cannot be reached, the following aspects can be selected to find the cause: whether the crimping range of the terminal and wire conductor is appropriate; Design of blade material and structure; Material of terminal, etc.

4. If the label is not sticky, we should not directly touch the adhesive surface with our hands when pasting it, first stick it on a clean metal, and then stick it on the line one by one.

5. You can do the salt spray test of the section.

6. Double-voltage terminals shall be tested for the tensile force of a single wire, and the test method is the same as that for the termination of a single wire.
