CONNECTOR AND CONNECTOR SET

WIPO Patent Application WO/2011/145512

A1

Provided is a connector wherein, when a plug is inserted in a socket, the plug is prevented from being erroneously inserted, and it is not necessary to rotate the plug to a great extent. A plug-in connector (1) is comprised of a pin plug (10) and a receptacle (20), and the pin plug (10) and the receptacle (20) are connected. A plurality of pin plug key protrusions (15) are spaced and arranged on a pin cover main body (14) of the pin plug (10) in the circumferential direction. A plurality of groups of a plurality of key grooves (28) spaced in the circumferential direction are arranged so as to be deviated from one another in the circumferential direction, in a socket cover (27) of the receptacle (20). A socket plug (30) may be used in place of the receptacle (20). As described above, there are a plurality of groups of grooves in the plug or the socket, and accordingly, the circumferential angle of the plug with respect to the socket can vary depending on the number of the groups of grooves. Therefore, the connector can reduce the twisting angle of a cable connected to the plug, and can reduce the load on the cable.
