ELECTRICAL PLUG CONNECTION HAVING A SELF-LOCKING FUNCTION

An electrical plug connector includes a plug connector housing, a locking member and a blocking member. The locking member is movable between a locking position and an unlocking position. In the locking position, the locking member is configured to prevent the plug connection from releasing and, in the unlocking position, the locking member is configured to allow it to be released. The blocking member is displaceable between a starting position and a blocking position. In the blocking position, the blocking member is configured to prevent the locking member from assuming the unlocking position. The blocking member is configured to strike a mating plug connector housing by shifting the plug connector housing relative to the mating plug connector housing, in such a way that the mating plug connector housing displaces the blocking member from the starting position into the blocking position counter to the plugging direction.
