How to obtain a reasonable insertion and extraction force for the pin connector?

The connector plug-in force test refers to the force required to insert and pull out the electronic connectors at both ends of the mating male and female. This test is suitable for various tests such as connector insertion force, pull-out force, plastic retention force, and service life. Reasonable plug-in force can ensure the reliability and stability of the connector after fitting. It is ensured that it is not difficult for the user to insert the adapter head, and at the same time it is not loosened during use.

If the connector insertion force is too large or too small, it is easy to reduce the life of the interface. The insertion force mainly depends on the friction coefficient between the pin and the socket. To get a reasonable insertion force, there are the following methods.

1. The base material chooses the material with good dimensional stability, rigidity and strength;

2. Improve the processing accuracy and consistency of the base, pins and sockets;

3. Choose corrosion-resistant high-quality coating materials and improve the quality of electroplating;
