Abstract: A housing component for a plug connector, in particular an end cap for a plug connector housing, having a cable-side axial portion and a plug-side axial portion adjoining the cable-side portion along a longitudinal axis. A cable bushing for a cable is formed in the cable-side portion and runs along the longitudinal axis. It is provided that the housing component has at least one fluid channel running in the cable bushing and being open towards the cable, in order to conduct away a fluid which has penetrated between the cable bushing and the cable in a defined manner into the plug-side portion. The fluid channel winds through the cable bushing at least in portions along the longitudinal axis. At least one outlet opening is formed in the plug-side portion in order to discharge the fluid from the housing component transversely to the longitudinal axis.

Abstract: A contact assembly (9) for an electrical plug-in connector (2), having a sleeve-shaped contact element (4, 5) made from a metallic first material. The contact element (4, 5) has a first lateral surface (10) for making electrical and mechanical contact with a mating contact element (7, 8) of a mating electrical plug-in connector (3) and a second lateral surface (11) different from the first lateral surface (10). It is provided that the contact assembly (9) has a delimiting element (12) preferably made of a second material different from the first material. The delimiting element (12) is fastened to the second lateral surface (11) of the contact element (4, 5) at least in certain portions and has a higher high-temperature strength than the contact element (4, 5).
