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 video signals between devices applied in consumer electronics, the present invention 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).
A socket (1) for a coaxial electrical plug-in connector, comprising an inner contact opening (2), having an inner contact element (3) arranged therein and comprising an outer plug (4) surrounding said inner contact opening (2) and being of a circular-cylindrical construction, said outer plug having an outer contact element, characterized in that said outer plug (4) consists of an electrically insulating material, with the outer contact element being designed and built as a contact strip (6) in its contact area, the curvature of said contact strip forming a circular-cylindrical helical curve on the outside of said outer plug (4).
An electrical connector plug (13) with a plug body (14) which an electrically insulating carrier element (15) for an inner contact pin (16) is affixed to, and comprised of an outer contact element (17) radially spaced from the inner contact pin (16) relative to the longitudinal axis of said plug (13), characterized in that the outer contact element (17) is designed and built in its contact area as an electrically conductive contact tongue (18), with electrically insulating clamping tongues (19) radially spaced from the inner contact pin (16) being provided to retain said plug (13) at a socket, said clamping tongues together with the contact tongue (18) being inwardly pressed against the outside of a circular-cylindrical outer plug of the socket by means of a clamping sleeve (22) axially guided movable at the plug body (14).
