The basic performance of connectors can be divided into three categories: mechanical, electrical, and environmental. Today we talk about the mechanical properties of the connector.
In terms of network connectivity, insertion force is an important mechanical property. The insertion force is divided into the insertion force and the extraction force (the extraction force is also called the separation force), and the requirements of the two are different. There are maximum insertion force and minimum separation force regulations in the relevant standards, which indicates that the insertion force is small from the point of view of use (thereby having a low insertion force LIF and a structure without ZIF insertion), and if the separation force is too small, It will affect the reliability of the contact. The insertion force and mechanical life of the connector are related to the plating quality (sliding friction coefficient) of the contact structure (positive pressure) contact portion and the dimensional accuracy (alignment) of the contact arrangement.
