With the rapid development of science and technology, the degree of automation and integration of all walks of life is increasing day by day. A single isolated instrument and instrument control equipment can no longer meet the development needs of contemporary industry. It is generally necessary to use a large number of instrument and control equipment to integrate and network to establish an entire system. As one of the most basic electrical components, the connector component is the link and bridge for communication between various devices in the entire automation control system, and plays the role of undertaking all signals and energy in the transmission system. The connector assembly generally includes two connectors that are plugged and mated with each other and a cable connected to the connectors. The two connectors are respectively a plug and a socket. With the plugging and disconnection of the two connectors, the control circuit On or off.

According to incomplete statistics, about 56% of electrical system failures throughout the year occur on the connector components connected to each other between devices. Once a failure occurs in this part, it will inevitably affect the local system, causing short circuits, open circuits, signal failures, Electrical faults such as loss of function, or even the failure of connector components at some critical equipment, will have a fatal impact on the entire system and cause the system to crash. Especially in some areas where the working environment is extremely harsh, such as nuclear power plants, weapons and equipment, petrochemicals, deep sea sealing, aerospace and other key equipment supporting connector components need to be able to withstand high temperature, high pressure, strong nuclear radiation, and Strong electromagnetic pulse interference, strong vibration resistance, long life, high reliability, etc., have very high performance requirements for connector components. In these extremely harsh working environments, non-metallic materials are easily affected by factors such as heat, radiation, moisture, vibration, etc., which accelerate their aging process, thereby weakening the overall performance of the material itself, and eventually causing the connector components to lose their proper functions. , an electrical failure has occurred.
