Abstract

A cable, in particular an audio cable, has an inner conductor surrounded by a dielectric and a conductive layer surrounding the dielectric. A separating layer is inserted between the dielectric and the conductive layer.

Claims

1. An audio cable comprising:

an inner conductor;

a dielectric directly surrounding the inner conductor;

a conductive layer surrounding the dielectric, the conductive layer being made of electrically conductive polyethylene;

one of a helical shield and a braided shield directly surrounding the conductive layer;

an outer jacket directly surrounding the one of the helical shield and the braided shield;

a separating layer inserted between the dielectric and the conductive layer, wherein the separating layer directly surrounds the dielectric, is directly surrounded by the conductive layer, and is made of polyvinyl chloride, and wherein the separating layer and the dielectric are movable relative to each other; and

wherein the inner conductor, the dielectric, the conductive layer, the one of the helical shield and the braided shield, the outer jacket, and the separating layer cooperate to form an audio cable that transmits audio signals.

2. The audio cable according to claim 1, wherein the separating layer is electrically non-conductive.

3. The audio cable according to claim 1, wherein the dielectric is made of one of solid polyolefins and foamed polyolefins.

4. The audio cable according to claim 1, wherein the audio cable only includes layers comprising the inner conductor, the dielectric, the conductive layer, the one of the helical shield and the braided shield, and the separating layer.

5. The audio cable according to claim 1 wherein the separating layer is separate from the dielectric.

6. The audio cable according to claim 1 wherein the separating layer and the conductive layer are movable relative to each other.

7. An audio cable comprising:

an inner conductor;

a dielectric directly surrounding the inner conductor;

a conductive layer surrounding the dielectric, the conductive layer being made of electrically conductive polyethylene;

one of a helical shield and a braided shield directly surrounding the conductive layer;

an outer jacket directly surrounding the one of the helical shield and the braided shield;

a separating layer inserted between the dielectric and the conductive layer, wherein the separating layer directly surrounds the dielectric, is directly surrounded by the conductive layer, and is made of polyvinyl chloride;

wherein the inner conductor, the dielectric, the conductive layer, the one of the helical shield and the braided shield, the outer jacket, and the separating layer cooperate to form an audio cable that transmits audio signals; and

wherein the separating layer and the dielectric layer are non-bonded, discrete layers that are movable relative to each other in an axial direction defined as extending along a length of the audio cable.
