Abstract: A plug connector for interlocking with a mating plug connector along an insertion direction. The plug connector includes: a plug connector housing configured to accommodate at least one contact element; a lever assembly swivelable between a first position and a second position; a cover; and a CPA including at least one blocking element. In the second position, the lever assembly is releasably latched to a latching structure. The CPA is situated at the cover, and is displaceable between an unblocking position and a blocking position along a displacement direction. The CPA includes a blocking element which in the blocking position of the CPA prevents a displacement of the latching structure for releasing the latch between the lever assembly and the latching structure.

Abstract: A plug connector to be plugged along a plug-in direction into a mating plug connector having a mating plug connector housing. The plug connector includes a plug connector housing; electrical contact elements, which are situated in the plug connector housing; a first lever system to reduce an operating force when the plug connector is plugged into and/or released from the mating plug connector, the first lever system being rotatably supported on the plug connector housing, the first lever system having: first and second arms, the second arm being pivotably situated on the first arm using a first joint pin, the first joint pin being movable in the plug connector housing in a first guide slot, which essentially extends along the plug-in direction, a first guide system between the first arm and the plug connector housing, and a second guide system between the second arm and the plug connector housing.

Abstract: A plug connector for plugging onto or into a counterpart plug connector, having at least two counterpart contact elements, in a plugging direction. The plug connector has a housing having a first plane that faces in the plugging direction. The housing has at least two contact chambers, each of which has an opening in the first plane. At least two of the contact chambers in the housing are embodied separately from one another. A wall, which protrudes from the first plane when viewed oppositely from the plugging direction, is disposed between at least two mutually adjacent contact chambers. Alternatively or additionally, at least one groove is disposed in the first plane between at least two mutually adjacent contact chambers.
