Plug Socket With A Locking Element Which Is Movable In the Plug-In Direction

A plug socket includes a recess receiving a charging plug in a plug-in direction and a locking element movable from a plug-in position into a blocking position. The recess terminates in an insertion opening in the plug-in direction and has an undercut acting in the plug-in direction to latch a latching element of the charging plug. The locking element in the plug-in position is located in the recess and overlaps the undercut transverse to the plug-in direction. The blocking position is spaced apart from the plug-in position in the plug-in direction and the locking element is located closer to the insertion opening in the blocking position than in the plug-in position.
