Abstract

A cable for use in computer networking for example has a jacket defining an internal space. A separator is located in the internal space and divides the space into three or more segments. The separator has a three or more radiating walls, at least one of which has an extension extending substantially normally from the wall to at least partially enclosed one of the segments. A conductor is located within each segment.

Claims

1. A cable comprising:

a jacket defining an internal space;

a separator located in the internal space and comprising three or more radiating walls dividing the space into three or more segments, at least one, but not all, of the walls comprising an extension extending from one side only of the wall substantially normally therefrom and approximately halfway across a segment to at least partially enclose one of the segments; and

a conductor located within each segment.

2. The cable of claim 1, wherein the extension includes an inwardly facing concave surface.

3. The cable of claim 1, wherein each conductor is one conductor of a twisted pair.

4. The cable of claim 1, wherein the separator divides the internal space into four quadrants.

5. The cable of claim 4, wherein the separator comprises four radiating walls and wherein each wall of a diametrically opposed pair of said walls includes a said extension.

6. The cable of claim 1, wherein the extension is curved so as to extend substantially tangentially to an inner surface of the jacket.

7. The cable of claim 1, wherein the separator is non-metallic.
