The basic performance of the connector can be divided into three categories: mechanical, electrical and environmental performance.
1 Mechanical Properties on the connection, the insertion force is an important mechanical properties. The insertion force is divided into the insertion force and the pulling force, and the two requirements are different. In the relevant standards have the maximum insertion force and the minimum separation force, which shows that the insertion force to be small, and the separation of Li Ruo is too small, it will affect the reliability of the contact.
Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a kind of durability index, in the national standard GB5095 it is called the mechanical operation. It is based on an insert and a pull out for a cycle, in order to complete the requirements of the plug connection after the cycle of the connector can be properly completed as a basis for the evaluation of its connection.
The insertion force and mechanical life of the connector are related to the coating quality of the contact parts of the contact structure and the arrangement of the contact parts.
2 the main electrical performance of the electrical connector includes contact resistance, insulation resistance and electrical strength.
