What bad problems should we pay attention to when testing the terminal wire?

In life, most people don't know much about the information about terminal wires. This is not surprising, because some terminal lines and electronic equipment are integrated! Just like the video cable in the TV, it is basically connected with the TV. Many people turn off the power directly when they don't watch TV, and the video cable will not be touched at all. If it is a good-quality product, there are few failures, and there is not much contact with it, so many people don't know much about these products.

In fact, high-quality terminal wires are processed through strict testing and processing! So what bad problems should we pay attention to in the detection of terminal wires? Let me share with you below!

Things to pay attention to when detecting terminal wires:

1. The two-core wire should be well controlled in the extruded wire, and there should be no wire with a bad core;

2. Observe whether the surface of the extruded wire body is scratched, grained, variegated, dirty, etc.;

3. The size of the cutting line cannot exceed the tolerance, and the thread ends should be aligned;

4. The surface of the wire should be clean, and there should be no dirt, scratches, scratches or damage on the outside of the inner core wire.

5. When punching terminals, there should be no defects such as deep punching, shallow punching, broken copper wires, or broken wires;

6. If the wire rack is injection molded, it is necessary to observe whether there are defects such as shrinkage, draping, lack of glue, deformation, etc.;

7. Whether the terminal wire penetrates into the plastic shell, whether the color and line sequence of the wire material is reversed or not in place;

8. Confirm that the terminal wire must be inserted into the heat shrinkable sleeve before passing through the plastic shell
