Patent ID: 8142218

Claim:
An electrical plug connector based on the push-pull system, with a plug component and a matching plug component that can be connected to the plug component, both of which each comprise one or several associated electrical contacts held by a contact carrier, and with a locking mechanism that is provided on the plug component and comprises at least one movable locking element with a latch surface that is associated, on the matching plug component, with a fixed locking element with a matching surface for the latch surface, with the plug component comprising a plug component housing with an axially displaceable sliding sleeve with at least one actuation element for the locking element formed on the inside wall, and wherein, when the plug component is connected to the matching plug component, a—in the plug-in direction—frontal section of the circumferential wall area of the plug component housing overlaps the matching plug component on the outside, wherein the locking element projects radially towards the inside beyond an inner surface of the circumferential wall area, the locking of the locking element with the matching locking element is achieved by moving the locking element transversely to the plug-in direction of the plug connector along the circumferential wall area, and the unlocking of the moveable locking element from the fixed locking element is accomplished by moving the locking element via the actuation element of the sliding sleeve transversely to the plug-in direction of the plug connector along the circumferential wall area, where the locking element moves when unlocking in opposite direction as while locking.
