Description

Electrical Connector Assembly

technical field

The utility model relates to an electric connector assembly.

Background technique

Electrical connector assemblies generally include two parts, a plug connector and a socket connector. The plug connector and the socket connector are inserted into each other, so that their electrical connection terminals are respectively in electrical contact with each other to realize electrical connection. In order to meet the needs of connecting different connection objects, the same type of electrical connector assembly usually has various specifications, for example, it may have two terminals, four terminals, six terminals or eight terminals. In use, plug connectors and socket connectors of the same specification need to be used together to achieve normal electrical connection functions. However, in practice, there are often problems such as plug connectors and socket connectors of different specifications being wrongly plugged into each other, resulting in failure of electrical connection. For example, a small-sized plug connector can easily be inserted into a larger-sized receptacle connector, causing electrical connection failure or other potential problems.
