Abstract

A guarded coaxial cable assembly include one or more conductors, one or more rails, and an outer jacket, the orientation of the rail and the conductor(s) within the outer jacket operative to limit conductor or conductor jacket deformations such as deformations due to bends and transverse loads when the cable assembly is squeezed between a sash and a jamb.

First claim

What is claimed is:

1. An assembly for guarding an electrical cable comprising:
the electrical cable including an electrical conductor within an insulating sheath;
a first metallic rail extending alongside the electrical cable;
an outer jacket that envelops the first metallic rail and the electrical cable;
the jacket having a generally rectangular cross-section with two opposed wide sides and two opposed narrow sides;
the opposed wide sides form opposed wide bearing surfaces for bearing transverse loads;
an orientation of the first metallic rail and the electrical cable within the jacket configured to limit deformation of the electrical cable resulting from one or more transverse loads applied to the opposed wide bearing surfaces; and,
the assembly undergoes bends of 90-degree or more as the assembly is squeezed between a sash and a mating U shaped jamb such that the opposed wide bearing surfaces are subjected to the transverse loads.

2. The assembly of claim 1 wherein the conductor is centrally located in the electrical cable.

3. The assembly of claim 2 further comprising a first metallic rail diameter equal to or less than a sheath diameter.

4. The assembly of claim 2 further comprising a first metallic rail diameter greater than a sheath diameter.

5. The assembly of claim 2 wherein the insulating sheath is surrounded by an electrical shield.

6. The assembly of claim 1 wherein the two opposed wide bearing surfaces include at least in part opposed planes.

7. The assembly of claim 1 wherein the two opposed wide bearing surfaces are described at least in part by parallel planes.

8. The assembly of claim 7 wherein the parallel planes are about 3 mm apart.

9. The assembly of claim 1 wherein the electrical conductor is one of a twisted pair of conductors.

10. The assembly of claim 9 further comprising a total of two or more twisted pairs of conductors between the first metallic rail and a second rail.

11. The assembly of claim 10 for interconnection with RJ45 or CAT 5 connectors.

12. An assembly for guarding an electrical cable comprising:
rails of metal, the electrical cable arranged between the rails;
the electrical cable including an electrical cable conductor within an insulating sheath;
the rails and electrical cable within an outer insulating jacket having a generally rectangular cross-section with a wide dimension and a narrow dimension; and,
an orientation of the rails and electrical cable within the jacket configured to protect the electrical cable from opposing forces that bear on wide dimension bearing surfaces and that pass through the narrow dimension;
wherein the assembly is capable of 90-degree bends as when squeezed between a window jamb mated with a window sash.

13. The assembly of claim 12 wherein the bends are facilitated by an outer jacket narrow dimension of about 2 mm to 6 mm.

14. The assembly of claim 12 wherein the bends are facilitated by an outer jacket narrow dimension of about 3 mm.

15. The assembly of claim 12 wherein the bends are facilitated by an outer jacket wide dimension of about 11 mm to 21 mm.

16. The assembly of claim 12 wherein the bonds are facilitated by an outer jacket wide dimension of about 16 mm.

17. The assembly of claim 12 wherein the rails transport electrical power or electrical signals.

18. The assembly of claim 12 wherein the electrical cable conductor is centrally located within the electrical cable.

19. The assembly of claim 18 wherein the insulating sheath is surrounded by an electrical shield.

20. The assembly of claim 12 wherein the electrical cable is for interconnection with one or more coaxial connectors.
