Abstract

The present invention is for a high performance data cable which has an interior support or star separator. The star separator or interior support extends along the longitudinal length of the data cable. The star separator or interior support has a central region. A plurality of prongs or splines extend outward from the central region along the length of the central region. Each prong or spline is adjacent with at least two other prongs or splines. The prongs or splines may be helixed or S-Z shaped as they extend along the length of the star separator or interior support. Each pair of adjacent prongs or splines defines grooves which extend along the longitudinal length of the interior support. At least two of the grooves have disposed therein an insulated conductor. The interior support can have a first material and a different second material. The different second material forms an outer surface of the interior support.

Claims

1. A data cable having a plurality of twisted pair conductors, a cable covering, and an interior support comprising:

said interior support being unshielded and having;

a longitudinally extending central portion forming a portion of said support;

a plurality of projections extending from said central portion;

each projection of said plurality of projections being adjacent to two other projections of said plurality of projections, said plurality of projections forming a plurality of adjacent projections;

an open space defined by each of said plurality of adjacent projections;

said cable covering contacting each projection;

only one twisted pair conductor from said plurality of twisted pair conductors disposed in each open space; and

wherein said cable covering includes an overall shield.

2. The cable of claim 1 wherein each of said projections is a projection selected from a group consisting of a prong, a spline, and an arm.

3. The cable of claim 1 wherein said open space is an open space selected from a group consisting of a channel, a groove, a duct, and a passage.

4. A data cable having a plurality of twisted pair conductors, a cable covering, and an interior support comprising:

said interior support being unshielded and having;

a longitudinally extending central portion forming a portion of said support;

a plurality of projections extending from said central portion;

each projection of said plurality of projections being adjacent to two other projections of said plurality of projections, said plurality of projections forming a plurality of adjacent projections;

an open space defined by each of said plurality of adjacent projections;

said cable covering contacting each projection;

only one twisted pair conductor from said plurality of twisted pair conductors disposed in each open space.

5. The cable of claim 4 wherein each of said projections is a projection selected from a group consisting of a prong, a spline, and an arm.

6. The cable of claim 4 wherein said open space is an open space selected from a group consisting of a channel, a groove, a duct, and a passage.

7. A data cable having a plurality of twisted pair conductors, a cable covering, and an interior support comprising:

said interior support being unshielded and having;

a longitudinally extending central portion forming a portion of said support;

a plurality of projections extending from said central portion;

each projection of said plurality of projections being adjacent to two other projections of said plurality of projections, said plurality of projections forming a plurality of adjacent projections;

an open space defined by each of said plurality of adjacent projections;

only one twisted pair conductor from said plurality of twisted pair conductors disposed in each open space.
