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 second plug further has a position-securing element (PSE) that is displaceable along a displacement direction perpendicular to the connecting direction and that mechanically locks the plugs together when the plugs are connected while the PSE is displaced to a slide position. 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.
