Abstract

The present invention relates to a prefabricated cable, to a cable plug connector arrangement, and to an electrical plug connection. A prefabricated cable ( 1 ) has a shielding foil ( 4 ), a shielding braid ( 5 ) which surrounds the shielding foil ( 4 ), and a cable sheath ( 6 ) which surrounds the shielding braid ( 5 ). The shielding braid ( 5 ) is exposed from the cable sheath ( 6 ) at a plug-side end ( 8 ) of the prefabricated cable ( 1 ). The shielding foil ( 4 ) has a dielectric foil ( 9 ) made of a dielectric material, and a metal coating ( 101, 102 ) on an outer lateral surface and on an inner lateral surface of the dielectric foil ( 9 ). The metal coating ( 101 ) on the outer lateral surface is electrically conductively connected to the metal coating ( 102 ) on the inner lateral surface in a plug-side end region ( 11 ) of the shielding foil ( 4 ) via at least one electrically conductive connection ( 12 ). According to the invention, the at least one electrical connection ( 12 ) is passed through the dielectric foil ( 9 ) in a plug-side axial end region of the shielding foil ( 4 ) and/or at least partially covers an end face of the dielectric foil ( 9 ) at a plug-side axial end of the shielding foil ( 4 ).

First claim

What is claimed is:

1 . A prefabricated cable comprising:
a shielding foil, a shielding mesh which encloses the shielding foil, and a cable sheath which encloses the shielding mesh, wherein the cable sheath exposes the shielding mesh at a plug-side end of the prefabricated cable, wherein the shielding foil comprises a dielectric foil of a dielectric material and a respective metallic coating on an outer lateral surface and on an inner lateral surface of the dielectric foil, and wherein the metallic coating on the outer lateral surface is electrically conductively connected to the metallic coating on the inner lateral surface of the shielding foil via at least one electrically conductive connection, and wherein the at least one electrical connection in each case a) is guided through the dielectric foil in a plug-side axial end region of the shielding foil; and/or b) at least partially covers an end face of the dielectric foil at a plug-side axial end of the shielding foil.

2 . The prefabricated cable as claimed in claim 1 , wherein the at least one electrical connection is spaced apart from the plug-side axial end of the shielding foil.

3 . The prefabricated cable as claimed in claim 2 , wherein the at least one electrical connection is spaced apart from the plug-side axial end of the shielding foil by less than one quarter of the wavelength of an electromagnetic wave that is to be transmitted by the cable during operation of the cable.

4 . The prefabricated cable as claimed in claim 1 , wherein the at least one electrical connection covers the entire end face of the dielectric foil at the plug-side axial end of the shielding foil.

5 . The prefabricated cable as claimed in claim 1 , wherein the electrically conductive connection between the metallic coating on the outer lateral surface and the metallic coating on the inner lateral surface is formed in an associated leadthrough of the shielding foil.

6 . The prefabricated cable as claimed in claim 1 , wherein the electrically conductive connection between the metallic coating on the outer lateral surface and the metallic coating on the inner lateral surface is formed in each case in an associated recess designed to delimit the shielding foil or in each case adjoining the shielding foil or in each case spaced apart from the shielding foil.

7 . The prefabricated cable as claimed in claim 1 , wherein multiple electrically conductive connections are formed between the metallic coating on the outer lateral surface and the metallic coating on the inner lateral surface.

8 . The prefabricated cable as claimed in claim 7 , wherein the multiple electrically conductive connections are preferably arranged in equidistant angular segments in relation to one another.

9 . The prefabricated cable as claimed in claim 1 , wherein the shielding foil, in at least one punctiform or areal region, is processed in each case such that the dielectric foil is displaced in each punctiform or areal region and the metallic coatings on the outer lateral surface and on the inner lateral surface of the shielding foil make electrical contact in each case.

10 . The prefabricated cable as claimed in claim 1 , wherein the metallic coating on the outer lateral surface and the metallic coating on the inner lateral surface are electrically connected to one another via the electrically conductive connection in such a way that a region between the metallic coatings is completely filled with metal.

11 . The prefabricated cable as claimed in claim 1 , wherein the exposed shielding mesh is enclosed by a supporting sleeve, wherein the exposed shielding mesh and the shielding foil are pushed back around the supporting sleeve, wherein the pushed-back shielding mesh has at least one region which is exposed by the pushed-back shielding foil in each case.

12 . The prefabricated cable as claimed in claim 11 , wherein multiple cutouts, which each extend parallel to one another in a longitudinal axial direction of the prefabricated cable, are formed in the pushed-back shielding foil starting from an end face of the pushed-back shielding foil, wherein a respective strip of the pushed-back shielding foil is formed between two mutually adjacently formed cutouts.

13 . The prefabricated cable as claimed in claim 12 , wherein each strip is respectively folded in such a way that at least a subregion of a folded region of the strip makes electrical contact with the shielding mesh.

14 . A cable plug connector arrangement, comprising:
a prefabricated cable as claimed in claim 1 , and a plug connector which is connected to the prefabricated cable at the plug-side end of the prefabricated cable, wherein the plug connector contains at least one outer-conductor contact element, wherein the outer-conductor contact element is electrically connected to the shielding mesh and/or to the shielding foil.

15 . The cable plug connector arrangement as claimed in claim 14 , wherein the shielding foil exposes the shielding mesh at least in one region in each case, wherein the metallic coating on the outer lateral surface and the metallic coating on the inner lateral surface of the shielding foil are electrically connected via an areal electrical connection between a surface of the shielding foil and a surface of at least one region of the shielding mesh that is exposed by the shielding foil.
