Mechanical properties Insertion force is an important mechanical property in terms of connection function.

The insertion force is divided into the insertion force and the extraction force (the extraction force is also called the separation force), and the requirements of the two are different. The maximum insertion force and minimum separation force are specified in the relevant standards, which indicates that the insertion force is small from the point of view of use (thereby having a low insertion force LIF and a structure without ZIF insertion), and the separation force is too small. It will affect the reliability of the contact.

Another important mechanical property is the mechanical life of the connector. Another important mechanical property is the mechanical life of the connector. Mechanical life is actually an indicator of durability, which is called mechanical operation in GB5095. It is a cycle of one insertion and one extraction, so that the connector can normally complete its connection function after the specified insertion cycle (such as the abnormal separation between the pin and the socket between the contact and the socket, It will cause serious consequences of power transmission and signal control interruption of the control system. Due to unreliable design, incorrect material selection, improper selection of molding process, poor quality of heat treatment, mold, assembly, welding, etc., the assembly is not in place, etc., which will cause poor fixing.

In addition, due to peeling, corrosion, bumping, plastic shell flashing, cracking, rough processing of the contact parts, deformation and other reasons, the appearance is poor, due to the poor positioning of the positioning and locking, the consistency of the processing quality is poor, the total separation force is too Poor exchange caused by a large number of reasons is also a common disease, frequently-occurring disease. These kinds of faults can generally be found in the inspection and use process in time.
