Abstract

A cable includes a first twisted pair of insulated conductors, a second twisted pair of insulated conductors, a shielding tape, and an outer jacket surrounding the first twisted pair of insulated conductors, the second twisted pair of insulated conductors and the shielding tape. The shielding tape includes a substrate and a plurality of conductive shielding segments. The plurality of conductive shielding segments is disposed on the substrate. Each conductive shielding segment is spaced from each immediately adjacent conductive shielding segment in a longitudinal direction.

First claim

What is claimed is:

1. A cable comprising:
a first twisted pair of insulated conductors;
a second twisted pair of insulated conductors;
a third twisted pair of insulated conductors;
a fourth twisted pair of insulated conductors;
a first shielding tape that extends between the first and second twisted pairs of insulated conductors and between the second and third twisted pairs of insulated conductors, the first shielding tape comprising:
a first substrate; and
a plurality of first conductive shielding segments disposed on the first substrate, each first conductive shielding segment being spaced from each immediately adjacent first conductive shielding segment in a longitudinal direction;

a second shielding tape that extends between the third and fourth twisted pairs of insulated conductors and between the first and fourth twisted pairs of insulated conductors, the second shielding tape comprising:
a second substrate; and
a plurality of second conductive shielding segments disposed on the second substrate, each second conductive shielding segment being spaced from each immediately adjacent second conductive shielding segment in a longitudinal direction; and

an outer jacket surrounding the first, second, third, and fourth twisted pairs of insulated conductors and the first and second shielding tapes; wherein:
the first shielding tape is joined with the second shielding tape at a joint;
the first substrate and the second substrate each comprise a pair of opposing surfaces and, for each of the first substrate and the second substrate, one of the opposing surfaces is devoid of any conductive shielding segments; and
the opposing surfaces that are devoid of any conductive shielding segments face each other.

2. The cable of claim 1 wherein the first shielding tape and the second shielding tape cooperate to form an X-shape.

3. The cable of claim 1 wherein each of the first substrate and the second substrate is formed substantially of biaxially-oriented polyvinylchloride terephthalate.

4. The cable of claim 1 wherein the conductive shielding segments are formed substantially of aluminum.

5. The cable of claim 1 wherein:
the first shielding tape further extends between the second twisted pair of insulated conductors and the outer jacket and between the third twisted pair of insulated conductors and the outer jacket; and
the second shielding tape further extends between the first twisted pair of insulated conductors and the outer jacket and between the fourth twisted pair of insulated conductors and the outer jacket.

6. The cable of claim 5 wherein the first shielding tape and the second shielding tape cooperate to form an S-shape.

7. The cable of claim 5 wherein the first substrate and the second substrate each comprise a pair of opposing surfaces and, for each of the first substrate and the second substrate, one of the opposing surfaces is devoid of any conductive shielding segments.

8. The cable of claim 5 wherein each of the first substrate and the second substrate is formed substantially of biaxially-oriented polyvinylchloride terephthalate.

9. The cable of claim 5 wherein the conductive shielding segments are formed substantially of aluminum.

10. The cable of claim 5 wherein the outer jacket is formed substantially of polyvinyl chloride.

11. The cable of claim 5 wherein each conductive shielding segment is also spaced from each immediately adjacent conductive shielding segment in a radial direction.

12. A cable comprising:
a first twisted pair of insulated conductors;
a second twisted pair of insulated conductors;
a third twisted pair of insulated conductors;
a fourth twisted pair of insulated conductors;
a substantially flat separator extending between the first and fourth twisted pairs of insulated conductors and between the second and third twisted pairs of insulated conductors but not extending between the first and second twisted pairs of insulated conductors nor between the third and fourth twisted pairs of insulated conductors, the substantially flat separator comprising:
a plurality of first conductive shielding segments, each first conductive shielding segment being spaced from each immediately adjacent first conductive shielding segment in a longitudinal direction; and
a first substrate overlying the plurality of first conductive shielding segments, wherein the first substrate is formed of a dielectric material; and

an outer jacket surrounding the first twisted pair of insulated conductors, the second twisted pair of insulated conductors, and the substantially flat separator.

13. The cable of claim 12 further comprising a second shielding tape surrounding the first twisted pair of insulated conductors, the second twisted pair of insulated conductors, and the substantially flat separator, the second shielding tape underlying the outer jacket, the second shielding tape comprising:
a second substrate; and
a plurality of second conductive shielding segments disposed on the second substrate, each second conductive shielding segment being spaced from each immediately adjacent second conductive shielding segment in a longitudinal direction.

14. The cable of claim 12 wherein the first substrate comprises opposing surfaces and one of the opposing surfaces is devoid of any first conductive shielding segments.

15. The cable of claim 12 wherein the first substrate is formed substantially of biaxially-oriented polyvinylchloride terephthalate.

16. The cable of claim 12 further comprising a second substrate underlying the plurality of first conductive shielding segments, wherein the second substrate is formed of a dielectric material.

17. The cable of claim 16 wherein the substantially flat separator further comprises:
an interior substrate formed of a dielectric material, the plurality of first conductive shielding segments being disposed on the interior substrate;
a plurality of second conductive shielding segments disposed on the interior substrate opposite the first conductive shielding segments, such that the interior substrate is sandwiched between the first conductive shielding segments and the second conductive shielding segments; and
a second substrate overlying the plurality of second conductive shielding segments, wherein the second substrate is formed of a dielectric material.
