Mechanical properties of automotive connectors

As for the connection function, the insertion force of the automobile connector is an important mechanical property. Insertion force is divided into insertion force and pull-out force. The requirements are different. The maximum insertion force and minimum separation force stipulated in the relevant standards indicate that the insertion force is small, and if the separation force is too small, it will affect the reliability of the contact.

Another important mechanical property of automotive connectors is mechanical life. Mechanical life is actually a kind of durability index. It is called mechanical operation in national standard GB5095. It takes one insertion and one pull-out as a cycle to judge whether the automobile connector can complete its connection function after the specified plug-in and pull-out cycle.

The plug-in and pull-out force and mechanical life of automobile connectors are related to the coating quality of the contact parts and the dimension precision of the contact parts.
