1. The line sequence of rubber casing is disordered

There are three or four holes in the plastic shell, and more than ten or twenty holes. Workers have been working for a long time in the process of penetrating the plastic shell, and the number of holes is large. It is very simple to inadvertently insert the lines in the wrong order. The lines originally intended to insert this hole have been inserted into the surrounding holes.

2. Poor thread cutting

In the process of wire cutting, there are often irregular incisions and damaged copper wires. For this, we should make corresponding adjustments to the knife values of wire rods of different standards before starting the machine. Before mass production, there should be an appropriate amount of trial products.

3. Poor terminal connection (terminal voltage)

In this process, it is generally due to the improper orientation of the terminal, the terminal does not completely cover the copper wire, and the terminal is excessively wrapped, which leads to the insertion of broken skin and other defects. These defects generally occur in the operation of manually striking the terminal. If the automatic machine is used to strike the terminal, it is only necessary to adjust the machine, which is less likely to occur.
