Abstract: In an aspect, a connection adapter is provided for connecting an earthing line to a metal protective hose, where the adapter includes an electrically conductive cylindrical body having an end face with an opening therein for passage of electrical conductors and the earthing line therethrough, and a receiving shoe connected to the end face, which is configured to seat the earthing line. The cylindrical body includes a plurality of inwardly facing tabs and is sized to fit over the metal protective hose. The tabs are configured to contact and slide over the metal protective hose so as to ensure an electrical connection is present between the metal protective hose and the earthing line.

Abstract: Connection adapter for connecting an earthing line to a metal protective hose comprising a line contact having at least one ring segment resting on the outer sheath of the earthing line and comprising a hose contact having a contact tab resting on the inner sheath of the protective hose.

Abstract: In an aspect, a connection adapter is provided for connecting an earthing line to a metal protective hose, where the adapter includes an electrically conductive substantially hollow cylindrical body having an end face with a pass-through opening therein for passage of electrical conductors and the earthing line therethrough, and a receiving shoe connected to the end face, which is configured to seat the earthing line. The cylindrical body includes a plurality of inwardly facing tabs and is sized to fit over the metal protective hose. The tabs are configured to contact and slide over and the metal protective hose.

Abstract: An electrical plug-in connection has a plug part with contact pins and a socket part with socket contacts. Coding elements interact in accordance with the lock/key principle in order for the two parts to be fixed in place in a pre-defined relative plug-in position. One or more protrusions, and apertures complementing the protrusions, are provided on the plug or socket parts. On being connected, one protrusion each is incorporated in an aperture, engaging behind the periphery of the associated aperture in the process. The aperture has two adjacent accommodating chambers. A plug-in accommodating-chamber periphery that is directed away from the plug-in direction, is at such a low level that the associated protrusion slides over it in the plug-in direction, and an arresting accommodating-chamber periphery is at such a high level to effectively prevent sliding of the protrusion over the arresting accommodating-chamber periphery.

Abstract: A universal housing with a plug-type connector has a high leakproofness rating. The universal housing has a base shell and a cover shell which is placed onto the base shell. The plug-type connector includes a plug part and a socket part, the socket part is associated with the base shell or the cover shell, and the plug part is associated with the respective other shell. In each case one adapter, whose outer contour is matched to the inner contour of the base shell or the cover shell, and whose inner contour is configured to be complementary to the outer contour of the socket part or plug part, is inserted into the base shell and into the cover shell. Owing to a modification of the adapter, the universal housing can therefore be matched to various plug-type connectors and seals them safely.
