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. 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, wherein said outer sheath comprises an elastically or flexibly embodied jacket 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 said electrical shield is formed by a mesh comprising electrically conductive stranded wires; and

wherein said outer sheath also surrounds a main area of said electrical shield annularly in cross-section, and a portion of said electrical shield is turned inside out in such a way that it is spaced apart from said 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 outer sheath of said electrical cable so those of said electrically conductive stranded wires that form a free end of said electrical shield extend inside a wall formed by said jacket.

2. The electrical cable as defined by claim 1, 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.

3. The electrical cable as defined by claim 1, wherein an end portion of said electrical cable comprises a dimensionally stable support sleeve that adjoins said jacket in a direction in which said electrical 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, wherein said second portion of said outer, inside-out portion comprises said those of said electrically conductive stranded wires that form said free end of said electrical shield.

4. The electrical cable as defined by claim 3, wherein said second portion of said outer, inside-out portion is incorporated into said jacket.

5. The electrical cable as defined by claim 1, 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.

6. The electrical cable as defined by claim 1, wherein said electrical shield is integrally formed with said wall formed by said jacket.
