Guarded coaxial cable assembly

1. An assembly including a guarded cable comprising:

a first metallic rail extending alongside an electrical conductor surrounded by an electrically insulating jacket;

the rail and the insulated conductor covered by an outer electrically insulating jacket;

the outer jacket having a generally rectangular cross-section with a wide by narrow dimension and a pair of generally opposed wide bearing surfaces for bearing transverse loads;

the rail operative to reduce outer jacket deformations resulting from one or more of the transverse loads applied to the bearing surfaces;

an orientation of the rail and the conductor within the outer jacket operative to limit conductor or conductor jacket deformation resulting from one or more of the transverse loads applied to the bearing surfaces; and,

the assembly capable of 90-degree bends about the wide jacket dimension as when the assembly is passed between a closed sliding sash and a mating U shaped jamb.

2. The assembly of claim 1 wherein the bearing surfaces include opposed planes.

3. The assembly of claim 1 wherein the bearing surfaces are described by parallel planes.

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

5. The assembly of claim 1 wherein the conductor is included in a twisted pair of conductors.

6. The assembly of claim 5 further comprising:

a total of 2 or more twisted pairs of conductors between the first rail and a second rail.

7. The assembly of claim 1 wherein a fluid jacket material fills in around the rail to form the outer jacket.

8. The assembly of claim 4 further comprising:

a rail diameter equal to or less than a conductor jacket diameter.

9. The assembly of claim 4 further comprising:

a rail diameter equal to or less than a conductor diameter.

10. The assembly of claim 6 wherein the pairs of conductors are suited for interconnection with an RJ45 or CAT 5 connector.

11. An assembly including a guarded cable comprising:

rails of metal and conductor pairs, the pairs in side by side arrangement between the rails and each conductor surrounded an electrically insulating jacket;

the rails and pairs in an outer jacket having a generally rectangular cross-section with a wide dimension and a narrow dimension;

the conductors protected from opposing forces bearing on wide dimension bearing surfaces and passing through the narrow dimension by orientation of the rails and pairs within the outer jacket; and,

the assembly capable of 90-degree bends when passing through a U shaped window jamb for receiving a window sash wherein a sash edge and floor of the U shaped window jamb impose the opposing forces on the bearing surfaces when mated.

12. The assembly of claim 11 wherein bending is facilitated by an outer jacket narrow dimension of about 2 mm to 6 mm.

13. The assembly of claim 11 wherein bending is facilitated by an outer jacket narrow dimension of about 3 mm.

14. The assembly of claim 12 wherein the bending is facilitated by an outer jacket wide dimension of about 11 mm to 21 mm.

15. The assembly of claim 12 wherein the bending is facilitated by an outer jacket wide dimension of about 16 mm.

16. The assembly of claim 11 wherein bending is facilitated by the pairs suited to interconnection with RJ45 or CAT 5 connectors.

17. The assembly of claim 11 wherein:

bending is facilitated by an outer jacket narrow dimension of about 2 mm to 6 mm and an outer jacket wide dimension of about 11 mm to 21 mm; and,

the rails transport electrical power or electrical signals.
