When inserting a military circular connector, the pins have to be opened with some force, while it is easier to pull them out. So it can be seen that the insertion of the circular electrical connector than the pull-out force is greater. Therefore, the interaction of the two forces of insertion and extraction is likely to cause wear and tear of the circular electrical connector. If you want to reduce wear, you can try the following methods.
1、you can improve the contact surface of the chrome hardness, which can reduce friction.
2、military circular electrical connector contact surface can be nickel-plated and then gold-plated, so than in the direct copper plating will produce less friction. The thicker the nickel layer, the stronger the wear resistance of the gold-plated layer.
3、the smoother the surface, that is, low roughness, then the friction will be smaller.
4、in the ordinary use of military circular electrical connectors in the process, pay attention to the maintenance of the electrical connector, to avoid man-made damage to the circular electrical connector.
