Abstract: An electrical contact element (ECE) for a plug connector includes a metal flat contact plug and a plastic body. The plastic body has a plug tip disposed on an insertion-side end face of the flat contact plug. The plug tip has a cross-sectional area including two undulated edge contours which extend symmetrically or asymmetrically with respect to a center axis of the cross-sectional area. A cross-sectional width between the edge contours varies continuously along the plug tip and has a local maximum(s) outside of end regions of the plug tip. The plug connector may include a mating contact element (MCE) having contact slats which contact the edge contours of the plug tip as the ECE is partially inserted along an insertion direction into the MCE and contact the contact surfaces of the flat contact plug as the ECE is fully inserted along the insertion direction into the MCE.

Abstract: A connection unit includes an insulating mounting frame and multiple resilient press-on contacts situated on the mounting frame. Each press-on contact includes a helical pressure spring that can exert an elastic force on a metal contact body. The contact body is connected in one piece to a connection plug or a connection socket. For each press-on contact, the mounting frame includes a hollow cylinder that forms a cavity within a circumferential wall, the cavity being closed off by a cover that is situated so as to be axially displaceable at the wall of the hollow cylinder. The pressure spring is situated inside the cavity, and with its elastic force acts on the cover. The contact body, in one piece, forms a contact disk that is situated on the outer side of the cover.

Abstract: A high-voltage plug assembly includes a stationary first plug and a second plug that is movable along a connecting direction of the plugs. The plugs have mutually complementary plug contact elements. The second plug further has connection lines connected to its plug contact elements. An outlet direction of the connection lines extends perpendicular to the connecting direction.

The PSE includes pairs of pins whose longitudinal axes are oriented in the PSE displacement direction and which are situated in pairs one behind the other in the PSE displacement direction. In the slide position in which the plugs are locked together, the pins respectively engage recesses of the plugs.

Abstract: A plug connector assembly includes first and second connector housings, a rotary lever, and a slide. The rotary lever has side faces each having a guide path into which in each case a guide pin on the second connector housing is inserted and is displaced along the guide path by rotation of the rotary lever whereby the connector housings move toward one another and electrical contact elements thereof connect.

A locking element of the slide is displaced relative to a locking element of the first connector housing when the slide linearly moves whereby a form-fit locking action between the locking elements may be established or cancelled.
