Overview of Model Specifications for Electric Vehicle Charging Pile Connectors

China [CN]

Connectors are bridges for the transmission and exchange of current and signals in electronic equipment. A connector, also known as a circuit connector, refers to a device that connects two conductors on a loop so that current or signals can flow from one conductor to another conductor, usually consisting of contacts, insulating parts, housings and accessories. Among them, the accessories, as an important part of the connector, can protect the termination of the wire and the contact body from damage, fix the cable and improve the electromagnetic shielding performance. Connectors are mainly used in communication, automotive, consumer electronics, rail transit, aerospace and military fields. Connectors in different application fields need to meet basic mechanical properties, electrical properties and environmental properties. At the same time, due to different application scenarios, the focus of connector functions and technical levels is also differentiated.

The automotive industry is an important application area of ​​connectors, mainly used in charging and vehicle systems. In recent years, with the continuous increase in the penetration rate of new energy vehicles, the electronic and intelligent degree of automobiles have gradually improved, and the demand for connectors, which are necessary for automobile manufacturing, has increased. According to Bishop&Associates data, in 2021, the communication and automotive industries will be the main downstream application fields of connectors, accounting for 23.47% and 21.86% respectively; consumer electronics and industry will account for 13.13% and 12.8% respectively; transportation and defense will account for 6.96% respectively and 5.99%; other fields accounted for 15.8%. As a mid-to-high-end connector product, automotive connectors mainly cover circular connectors, RF connectors, FCP connectors, I/O connectors and other types, and are widely used in power systems, body systems, information control systems, safety systems and In the field of automotive equipment, the quality and performance requirements of connector products have been further improved.
