Abstract

An electrical cable including an inner conductor arrangement having a longitudinally extended conductor. The electrical cable further including an outer sheath that surrounds the inner conductor arrangement annularly in cross-section, and an electrical shield that extends between the inner conductor arrangement and the outer sheath, wherein a portion of the electrical shield is turned inside out in such a way that it is spaced apart from a main area of the electrical shield. The portion defines an inside-out portion and extends between the inner conductor arrangement and the outer sheath transversely to a direction in which the electrical cable extends. In addition, an exterior region of the inside-out portion of the electrical shield is incorporated in at least some portions into the sheath of the electrical cable.

Claims

1-15. -15. (canceled)

16. An electrical cable comprising:

an inner conductor arrangement comprising a longitudinally extended conductor;

an outer sheath that surrounds said inner conductor arrangement annularly in cross-section; and

an electrical shield that extends between said inner conductor arrangement and said outer sheath, wherein a portion of said electrical shield is turned inside out in such a way that it is spaced apart from a main area of said electrical shield and defines an inside-out portion, said inside-out portion extends between said inner conductor arrangement and said outer sheath transversely to a direction in which said electrical cable extends; and

wherein an exterior region of said inside-out portion of said electrical shield is incorporated into at least some portions of said sheath of said electrical cable.

17. The electrical cable as defined by claim 16, wherein said exterior region of said inside-out portion is incorporated into said sheath of said electrical cable in such a way that said exterior region of said inside-out portion is pressed into a molten portion of said sheath.

18. The electrical cable as defined by claim 16, wherein said electrical shield is formed by a mesh comprising many electrically conductive stranded wires.

19. The electrical cable as defined by claim 17, wherein said electrical shield is formed by a mesh comprising many electrically conductive stranded wires.

20. The electrical cable as defined by claim 16, wherein said electrical shield surrounds said inner conductor arrangement annularly in cross-section.

21. The electrical cable as defined by claim 16, wherein said sheath of said electrical cable comprises an elastically or flexibly embodied jacket, which surrounds said inner conductor arrangement and said main area of said electrical shield annularly in cross-section.

22. The electrical cable as defined by claim 21, wherein said outer sheath comprises a jacket, wherein an end portion of said electrical cable comprises a dimensionally stable support sleeve that adjoins said jacket in said direction in which cable extends;

and

wherein said outer, inside-out portion of said electrical shield extends with a first portion on an exterior of said support sleeve that is remote from said inner conductor arrangement and with a second portion of said outer, inside-out portion extending inside said jacket.

23. The electrical cable as defined by claim 22, wherein said second portion of second portion of said outer, inside-out portion is incorporated into said jacket.

24. The electrical cable as defined by claim 16, wherein said portion of said electrical shield is incorporated into said outer sheath of said electrical cable only so far that said portion of said electrical shield does not protrude in a direction of an interior of said longitudinally extended conductor past an inside of said outer sheath of said electrical cable oriented toward said inner conductor arrangement.

25. A method for the manufacture of an electrical cable, the method comprising:

furnishing an inner conductor arrangement, wherein said inner conductor arrangement comprises an electrical conductor extending in a longitudinal direction, and which is surrounded by an outer sheath, and an electrical shield extends between said inner conductor arrangement and said outer sheath;

turning a portion of said electrical shield inside out in such a way so as to form an inside-out portion that extends along an exterior, remote from said inner conductor arrangement of said sheath; and

incorporating said inside-out portion of said electrical shield in a portion into said outer sheath of said electrical cable, so that a portion of said inside-out portion extends in a wall formed by said sheath.

26. The method as defined by claim 25, further comprising heating said sheath of said electrical cable for said incorporation of portion of said inside-out portion of said electrical shield into said outer sheath.

27. The method as defined by claim 25, further comprising pressing said portion of said electrical shield into said sheath of said electrical cable.

28. The method as defined by claim 27, wherein said pressing is performed by means of at least one movable tool part that is heatable by a heating device in such a way that said sheath of said cable is melted upon contact with said tool part.

29. The method as defined by claim 25, wherein said electrical shield is formed by a mesh comprising many electrically conductive stranded wires.

30. A device for manufacturing a cable, said device comprising:

a first tool part; and

a second tool part movable relative to said first tool part, wherein in a first relative position of said first tool part and said second tool part an opening is formed with a cross-section such that a cable to be processed can be introduced therein, and a portion of said cable extends through said opening;

wherein in said portion of said cable and on an exterior of an outer sheath of said cable, an inside-out portion of an electrical shield of said cable extends, and which said first and second tool parts are movable into a second relative position, in which said opening has a cross-section reduced in such a way that said inside-out portion of said electrical shield is pressed into said outer sheath of said cable.

31. The device as defined by claim 30, wherein said first tool part comprises a first receptacle area and said second tool part comprises a second receptacle area, wherein said first and second receptacle areas form said opening;

and

a heating device is associated with said first receptacle area to enable melting said outer sheath of said cable to be processed.

32. The device as defined by claim 30, wherein said electrical shield is formed by a mesh comprising many electrically conductive stranded wires.

33. A method of using a device for manufacturing a cable, said device comprising a first tool part and a second tool part movable relative to said first tool part, the method comprising:

moving said first tool part and said second tool part to a first relative position so as to form an opening with a cross-section;

introducing a cable into said first open so that a portion of said cable extends through said first opening, wherein in said portion of said cable and on an exterior of an outer sheath of said cable, an inside-out portion of an electrical shield of said cable extends; and

moving said first tool part and said second tool part to a second relative position so as to reduce said cross-section of said opening to such an extent that said inside-out portion of said electrical shield is pressed into said outer sheath of said cable.

34. The method according to claim 33, further comprising melting said outer sheath of said cable while said cable is held by said first and second tool parts at said second relative position.

35. The method as defined by claim 33, wherein said electrical shield is formed by a mesh comprising many electrically conductive stranded wires.
