The Factors of Connector Insertion and Extraction Force

1. Contact pressure

Contact pressure is an important factor affecting the insertion and withdrawal force of connector contact resistance control

2. Number of contact parts

The more the number of contact parts, the greater the pulling power of the inserting and pulling force, which is related to the performance of the material and the deformation of the processing process contact parts, the greater the contact pressure, the greater the inserting and pulling force will cause the plug to be difficult to insert and pull.

3. Matching error of contact parts

The existence of connector assembly error and manufacturing error leads to the skew of the pin in the process of inserting and removing the contact, and there will be additional extrusion pressure between the wall of the pin jack

4. Surface friction coefficient

The size of the connector friction is related to the positive pressure and friction coefficient between the contact surface, the greater the surface roughness, the greater the insertion and withdrawal force, which will constitute wear to the contact.
