| 摘要 |
The invention proposes an electrical plug-type connector for making contact with a mating plug-type connector, said plug-type connector having a displaceable locking and unlocking apparatus, which exerts a constant pressure on the apparatus by means of a double-sided torsion spring in such a way that the plug-type connector is forcibly locked when contact is made between said plug-type connector and the mating plug.;In this case, the pressure exerted by the torsion spring legs is transferred to two axially displaceable sliding posts, which are again part of the unlocking apparatus. Furthermore, the unlocking apparatus has two sliding arms, which can be displaced in a tongue-and-groove guide, at least in regions, within corresponding recesses and flush with respect to the side faces of the plug-type connector housing. |

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. |
