Abstract: An electrical plug-in connector is in the form of a cable plug connector or a device connector plug. A particularly reliable and tightly-sealed connector may be achieved, whereby the plug-in connector is disclosed, and contains a connector mechanism, which is self-closing on bringing the parts for connection together. The plug-in connector further contains a radial seal for sealing the parts connected together.

Abstract: A leadthrough adapter for connecting the components installed in a switchgear cabinet to external electric conductors. The adapter is located in a wall of the switchgear cabinet housing and one or more bushings are situated on the face of the adapter. The bushings can be accessed from the outside of the switchgear cabinet and plug-in connectors can be inserted into the bushings in order to connect the external electric conductors. Electric and/or electronic functional parts for the components that are accommodated inside the switchgear cabinet are arranged directly on the back of the adapter which faces towards the inside of the switchgear cabinet.
