When inserting the electrical connector, the pin must use a certain force to open, and it is easier to pull it out. It can be seen that the insertion force of the circular electrical connector is greater than that of the pull-out force. Therefore, the interaction of the two forces of insertion and extraction is easy to cause the wear of the circular electrical connector. If you want to reduce wear, you can try the following methods:

1. The hardness of the gold plating layer on the contact surface can be improved, which can effectively reduce friction.

2. The contact surface of military circular electrical connector can be nickel plated and then gold plated, which will produce less friction than gold plating directly on copper. The thicker the nickel layer, the stronger the wear resistance of the gold plating layer.

3. The smoother the surface, that is, the lower the roughness, the smaller the friction.

4. In the process of using the military circular electrical connector at ordinary times, pay attention to the maintenance of the electrical connector to avoid man-made damage to the circular electrical connector.
