Pin jack electrical connector As a basic electrical component, it is widely used in electrical circuits in aviation, aerospace, hydropower, electronic communications, transportation, oil drilling and other industries, playing the role of circuit connection or disconnection, realizing the transmission of electrical signals and electrical connections between various electronic equipment devices. As a new means of transportation, under the requirements of global energy conservation and emission reduction, low-carbon environmental protection and sustainable development, the launch of new energy electric vehicles represented by Tesla has triggered the rapid development of the entire new energy electric vehicle industry. With the strong injection of traditional car companies and capital from all walks of life in China, the new energy electric vehicle industry and related enterprises have sprung up everywhere.

With the rapid development of vehicle enterprises, the use of pin jack electrical connectors, a key component required for the control of vehicle electronic control, circuit and signal system, has greatly increased. It is estimated that with the improvement of drivers' requirements for driving comfort and safety and reliability of new energy electric vehicles, it is expected that the number of pin jack electrical connectors used on each new energy electric vehicle will reach 600-1,000 in the future, far larger than the number currently used. According to statistics, 70% of the current failures or faults of various control systems mainly come from the failure of components, and about 40% of these 70% of component failures are caused by the failure of the pin jack electrical connector. As the core key component of signal connection transmission installed in the pin jack electrical connector, the reliability of the contact terminal directly affects the reliability of the pin jack electrical connector and the reliability of the entire system.
