1: Mechanical properties: Insertion and extraction forces are important mechanical properties in terms of connection function. Plug into and out of force into the pull-out force (pull-out force also known as the separation force), the two requirements are different. There is a maximum insertion force and a minimum separation force in the relevant standard, which indicates that the insertion force is small from the point of view of use (thus, there is a structure with a low insertion force LIF and a non-insertion force ZIF) and the separation force is too small, It will affect the reliability of the contact.
2: Electrical Performance: The connector's main electrical properties include contact resistance, insulation resistance and dielectric strength.
3: Environmental Performance: Common environmental performance, including temperature, humidity, salt spray resistance, vibration and impact.
