Mechanical properties of the connector

Mechanical properties In terms of the connection function, the 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.

Another important mechanical property is the mechanical life of the connector. Mechanical life is actually an indicator of durability, which is called mechanical operation in GB5095. It takes one insertion and one extraction as one cycle to judge whether the connector can complete its connection function (such as contact resistance value) after the specified insertion and removal cycle. 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.
