Abstract:
1. A locking apparatus for an electrical plug-type connector ( 100 ), said plug-type connector being formed from a two-part housing ( 200 , 300 ) with a cable connection side ( 104 ) for electrical cables ( 710 ) and a plug-in side ( 102 ) formed from a printed circuit board ( 700 ) and having electrical contacts ( 701 ), for making direct contact with a mating plug ( 10 ) with the electrical contacts thereof, the plug-type connector ( 100 ) being forcibly locked when plugged with the mating plug ( 10 ), characterized in that the two-part housing comprises a base housing ( 200 ) and a housing upper part ( 300 ), within which a displaceable unlocking device ( 400 ) is arranged, in that the unlocking device ( 400 ) has two sliding posts ( 405 ), on which a torsion spring ( 500 ), connected to the housing, upper part. acts, said torsion spring having two spring legs ( 501 ) and bringing about forced locking, acting in the axial direction, with the mating plug ( 10 ), and in that the locking is released with an axially reversible movement counter to the spring action wherein said torsion spring ( 500 ) has a rotary loop ( 502 ) and is held in a separate spring chamber ( 305 ) within the housing upper part ( 300 ) by means of a guiding post ( 307 ), located within the housing upper part and aligned perpendicularly in the spring chamber ( 305 ), said rotary loop encompasses said guiding post, wherein said two spring legs ( 501 ) of the torsion spring ( 500 ) exert a force acting axially in the sliding direction on said sliding posts ( 405 ) of the unlocking device ( 400 ) which reach into the spring chamber ( 305 ) of the housing upper part, and wherein said unlocking device ( 400 ) has two sliding arms ( 403 ), which are arranged in axially displaceable fashion within a recess ( 204 , 312 ) in the side walls ( 202 , 302 ) of the plug-type connector ( 100 ), and wherein said sliding posts ( 405 ) are integrally formed perpendicularly within a central part ( 406 ) between the sliding arms ( 403 ) of the unlocking device.
