Plastic Injection Molded Connector Accessories

Mechanical properties of injection connector fittings as far as connection functions are concerned, insertion and extraction forces are important mechanical properties. Plug force is divided into insert force and pull out force (pull out force is also called separation force), the requirement of both is different. In the relevant standards, there are provisions for maximum insertion force and minimum separation force, which indicate that, from the point of view of use, the insertion force should be small (hence the structure of LIF with low insertion force and ZIF without insertion force), and if the separation force is too small, it will affect the reliability of contact.
Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a kind of durability index, which is called mechanical operation in GB5095. It is based on a cycle of one insert and one pull, and whether the connector can normally complete its connection function (such as contact resistance) after the specified plug cycle. The plug force and mechanical life of the connector are related to the plating quality (sliding friction coefficient) of the contact part of the contactor structure (positive pressure size) and the dimensional accuracy (alignment) of the contactor.
