Main performance of  Cnc Connector      

     The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance and environmental performance.

Mechanical performance

   In terms of connection function, plugging and unplugging force is an important mechanical performance. Plug-in force is divided into insertion force and extraction force (extraction force is also called separation force), and the requirements of the two are different. The relevant standards have provisions for maximum insertion force and minimum separation force, which shows that from the perspective of use, the insertion force should be small (thus there are low insertion force LIF and no insertion force ZIF structures), and if the separation force is too small, it will affect the reliability of contact.

   Another important mechanical performance is the mechanical life of the connector. 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 extraction as a cycle, and whether the connector can normally complete its connection function (such as contact resistance value) after the specified plug-in and unplug cycle is used as the basis for judgment. The plug-in force and mechanical life of the connector are related to the contact structure (positive pressure size), the quality of the contact part coating (sliding friction coefficient) and the contact arrangement size accuracy (alignment).
