Plug connection locking mechanism

摘要

The arrangement includes a plug (1), a socket (2) having a casing (10) with an elastic bolt arm (13) and a plug recording space (11), in which a plug casing (4) is insertable. The plug casing comprises an action projection (9) and a slide element (3) placed on the socket casing. The action projection lifts the bolt arm when the plug casing is inserted, so that a part of it engages in the bent reception space and pushes an internal lateral surface (17a) against a lateral surface (13b) of the bolt arm.
