COAXIAL PLUG-IN CONNECTOR

The invention relates to a socket (1) for a coaxial electrical plug-in connector as well as a pertaining plug. The socket (1) is comprised of an inner contact opening (2) with an inner contact element (3) arranged therein. The inner contact opening (2) is surrounded by an outer plug (4) being of a circular- cylindrical construction, said plug having an outer contact element. To improve the electrical properties of such a socket on transmission of audio and vide o signals between devices applied in consumer electronics, the present inventi on proposes an outer plug (4) to be made of an electrically insulating material , with the outer contact element being designed and built as a contact strip (6) in its contact area, with the curvature of said contact strip forming a circular- cylindrical helical curve on the outside of said outer plug (4).
