Common Faults in Wire Harness Processing and Their Solutions

1. The thread sequence of the rubber shell is disordered.

There are three or four holes in the rubber shell, and more than ten or twenty holes. Workers work for a long time in the process of wearing the rubber shell, and the number of holes is large, it is very simple not to pay attention to the wrong order of the wires, but the wires that were originally to be inserted into this hole were inserted into the surrounding holes.

2. Poor cutting line

in the process of wire cutting, there are often irregular incisions and damaged copper wires. For this, we should adjust the tool value of different standard wires before starting up, there should be an appropriate amount of test products before mass production.

3. Poor terminal punching (end pressure)

in this process, the orientation of the terminal is generally inappropriate, the terminal does not completely wrap the copper wire, and the terminal is excessively wrapped, resulting in the insertion of the outer skin, etc. These defects generally occur in the operation of manual terminal punching, if you use an automatic machine to hit the terminal, you only need to adjust the machine, and the probability of occurrence is small.
