Locking device for electrical connectors

Locking device for an electrical connector (100) comprising a two-part shell (200, 300) with a cable side (110) for electrical cables (810) and a connecting side (120) in form of a printed circuit board (820) with electrical contacts (830) for directly contacting a mating connector (10), and a locking latch (600), in which the electrical connector (100) is automatically locked with the mating connector (10) when it is pushed into the mating connector (10), wherein inside the sliding element (400) a locking latch (600) is arranged, wherein the sliding element (400) is arranged inside the two-part shell (200, 300) for a displacement of a certain distance, wherein the locking latch (600) is mounted rotatably inside a mount (380) of the bottom shell (300), and wherein a hook (620) on the locking latch (600) performs a short lifting movement when the sliding element (400) is displaced axially, so that an unlocking or locking action with the correspondingly provided mating connector (10) results.
