Background

The conventional connector includes a male terminal and a female terminal that are plugged into each other, that is, the two cables are electrically connected by plugging and unplugging the plug and the socket. In view of the reliability of the connection between the plug and the socket to prevent the plug and the socket from being separated due to vibration and the like during use, it is known to provide a snap/engagement portion (i.e., a single snap/engagement portion) on each of the plug and the socket to achieve locking against release. This conventional locking system can substantially meet the functional requirements in the case of a low-voltage connection, for example in the case of a low-voltage circuit on a vehicle propelled by an internal combustion engine.
