Abstract

A multi-twisted pair cable including a plurality of twisted pairs positioned within pockets of a filler. The filler including shaped elements having retaining members for retaining the twisted conductor pairs of the plurality within the pockets of the filler. At least one of the shaped elements of the filler having an end piece that creates a helical ridge in the jacket of the multi-twisted pair cable.

Claims

1. A cable, including:

a) a plurality of twisted conductor pairs;

b) a filler defining pockets, each one of the pairs of the plurality of twisted conductor pairs being positioned within one of the pockets, the filler including;

i) a plurality of extensions; and

ii) shaped elements located at free ends of each of the extensions, each of the shaped elements including a retaining member for retaining the twisted conductor pairs within the pockets of the filler, at least one of the shaped elements including an end piece located a distance farther from a center of the filler than other shaped elements; and

c) a jacket including a helical ridge formed by the end piece of the filler;

d) wherein the retaining members of the filler are constructed such that the twisted conductor pairs are zip-fit within the pockets of the filler.

2. The filler of claim 1, wherein the retaining members of the shaped elements have a major length, the major length being oriented transverse to a length of the respective extension.

3. The filler of claim 2, wherein the retaining members of the shaped elements have a triangular shape.

4. The filler of claim 1, wherein the end piece of the least one shaped element has an oval cross-section.

5. The filler of claim 1, wherein the shaped elements include a first shaped element and a second shaped element, the first and second shaped elements being different from one another.

6. The filler of claim 5, wherein the first shaped elements located at the free ends of the extensions define a major filler dimension, and the second shaped elements located at the free ends of the extensions define a minor filler dimension.

7. A filler for use in a multi-twisted pair cable, the filler comprising:

a) a plurality of extensions, each of the extensions including a first end and a second end, the first ends of the extensions being joined to define a center of the filler; and

b) shaped elements located at the second ends of the extensions, each of the shaped elements including;

i) a retaining member, the retaining member being oriented in a generally transverse position relative to the extensions;

c) wherein at least one of the shaped elements includes an end piece having a circular cross-section, the end piece being located a distance farther from the center of the filler than the other shaped elements.

8. The filler of claim 7, wherein the extensions define four pockets each sized to receive a twisted conductor pair.

9. The filler of claim 7, wherein the retaining members of the shaped elements have a triangular shape.

10. The filler of claim 7, wherein the retaining members of the shaped elements have a rectangular shape.

11. The filler of claim 7, wherein the shaped elements include a first shaped element and a second shaped element, the first and second shaped elements being different from one another.

12. A filler for use in a multi-twisted pair cable, the filler comprising:

a) radial spokes defining a number of pockets, the radial spokes partially defining a major filler dimension and a minor filler dimension;

b) first shaped elements located at the ends of the radial spokes, the first shaped elements further defining the major filler dimension; and

c) second shaped elements located at the ends of the radial spokes, the second shaped elements further defining the minor filler dimension, the second shaped elements being different from the first shaped elements;

d) wherein each of the first and second the shaped elements includes a retaining member that retains twisted conductor pairs within the pockets defined by the radial spokes, and wherein only the first shaped elements further include an end piece radially located beyond the retaining member.

13. The filler of claim 12, wherein the retaining members are oriented generally transverse to the respective minor and major filler dimensions.

14. The filler of claim 12, wherein the retaining members of the first and second shaped elements have a triangular shape.

15. The filler of claim 12, wherein the retaining members of the first and second shaped elements have a rectangular shape.

16. The filler of claim 12, wherein the end pieces of the first shaped elements have oval-shaped cross-sections.
