Mechanical Properties Of The Three Basic Properties Of Heavy-duty Connectors

The basic performance of heavy power connector can be divided into three categories: mechanical performance, electrical performance and environmental performance.
1.heavy duty wire connectors Mechanical performance In terms of connection function, plugging and unplugging force is an important wire connector heavy duty mechanical performance. Plug-in force is divided into insertion force and pull-out force (pull-out force is also called separation force), and the requirements of the two are different. In the relevant standards, there are provisions for maximum insertion force and minimum separation force, which shows that from the perspective of use heavy duty electric cable connectors, the insertion force should be small (thus there are structures of low insertion force LIF and no insertion force ZIF), and if the separation force is too small, it will affect the reliability of contact.
Another important mechanical performance is the mechanical life of heavy duty automotive electrical connectors. Mechanical life is actually a durability indicator, which is called mechanical operation in the national standard GB5095. It is based on one insertion and one pull-out as a cycle, and whether heavy duty 12v connectors can normally complete its connection function (such as contact resistance value) after the specified plug-in cycle is used as the basis for judgment.
The insertion and extraction force and mechanical life of heavy duty 12 volt connectors are related to the contact structure (positive pressure), the quality of the contact coating (sliding friction coefficient) and the contact arrangement dimensional accuracy (alignment).
