Mechanical Properties Of Connectors
Nov 20, 2018

Mechanical properties As far as the connection function is concerned, the interpolation force is an important mechanical performance. The interpolation force is divided into insertion force and pull-out output (pulling output is also known as Separation Force), the requirements of the two are different.

The maximum insertion force and minimum separation force are specified in the relevant standards, which indicates that, from the point of view of use, the insertion force is small (thus having a low insertion force lif and a structure without insertion force ZIF), and if the separation force is too small, it will affect the reliability of the contact. Another important mechanical performance is the mechanical life of the connector. Mechanical life is actually a durability (durability) indicator, which is called mechanical operation in the GB GB5095. It is based on one insertion and one pull-out as a loop to evaluate whether the connector can properly complete its connection function (such as contact resistance value) after the specified interpolation cycle.

The interpolation force and mechanical life of the connector are related to the quality of the coating (sliding friction coefficient) and the size accuracy (alignment) of the contact parts in the contact part structure (positive pressure size).
