Knowledge of the basic properties of the connector of the connector can be divided into three categories: the mechanical properties, electrical properties, and environmental performance. Another important mechanical properties of the mechanical life of the connector. Mechanical life is actually a durability (durability) indicators in the GB GB5095 called it a mechanical operation. It is first inserted and a pull out as one cycle to cycle after a predetermined mating connector can normally complete its connection function (such as a contact resistance value) as the basis for evaluation.
1. Mechanical properties on connectivity, the insertion force is important to the mechanical properties. Insertion force into the insertion and extraction force (pull force known as the separation force), both requirements are different.
2. The main electrical properties including electrical performance of the connector contact resistance, insulation resistance and dielectric strength.
3. Environmental performance of common environmental performance, including temperature, humidity, salt fog, vibration, and shock.
