Abstract: A male single-pin connector is provided. The single-pin connector includes a contact, which has a contact housing, wherein the contact housing has at least one limiting protrusion on an outer surface; and a cover for receiving the contact, wherein the inner surface of the cover has an inwardly protruding limiting portion and an internal thread portion, wherein the internal thread portion is closer to the insertion side than the limiting portion; wherein the male single-pin connector also includes a retaining ring having an outer thread portion, wherein, after insertion of the contact housing into the cover against the plug-in direction, the retaining ring is screwed into the cover until the limiting protrusion comes into contact with the limiting portion, thereby fixing the contact housing in the cover by a screw connection. A female multi-pin connector and a connector system is also provided.

Abstract: Disclosed is a connector housing module which comprises a housing body having a housing body end region, which surrounds an opening in said housing body, and having a sealing ring, a lateral face of said housing body end region being in detent engagement with a lateral face of the sealing ring. A connector housing is also disclosed. The connector housing comprises a connector housing module and a hood, wherein an end face of the hood surrounding an opening in said hood, when the hood and the housing body are in a closed state, in part directly contacts an end face of the housing body end region and in part presses a curved edge of a bulge of the sealing ring so that the bulge is completely interlockingly engaged with a recess of the housing body, thereby improving the electromagnetic shielding capacity and the water tightness of the entire connector housing.

Abstract: The attachment housing for connecting at least one high-performance plug connector comprises at least two housing elements. At least one housing element is mounted on a support structure and designed to accommodate at least one electrically conductive cable. The housing element and the support structure each have at least one corresponding opening, which openings allow at least the feed-through of an electrically conductive cable. The attachment housing also comprises at least one counter-pressure frame which is located on the side of the support structure opposite the attachment housing and is connected to the attachment housing.
