Abstract

A cable includes a flexible jacket extending along a length and first and second lateral axes perpendicular to the length. The jacket also defines flat major surfaces that are parallel to each other and spaced apart on opposite sides of the first lateral axis. First and second inner wire assemblies extend within the jacket. The jacket maintains the first and second inner wire assembles in predetermined positions along the first lateral axis within 0.05 mm of each other and disposed on opposing sides of the second lateral axis. First and second outer wire assemblies also extend within the jacket. The outer wire assemblies include a wire of conductive filaments and an insulating layer of an enamel material surrounding the wire. The jacket maintains the first and second outer wire assemblies in positions along the first lateral axis and spaced apart from the first and second inner wire assemblies.

First claim

The invention claimed is:

1. A connection cable, comprising:
a generally flexible jacket extending along a length thereof and along first and second lateral axes perpendicular to the length thereof and defining substantially flat first and second major surfaces generally parallel to each other and spaced apart on opposite sides of the first lateral axis;
first and second inner wire assemblies extending within the jacket, each of the inner wire assemblies including a wire comprised of a plurality of conductive filaments, a shielding layer surrounding the wire, and an outer insulating layer surrounding the shielding layer and spaced apart from the wire, the jacket maintaining the first and second inner wire assembles in predetermined positions along the first lateral axis in within about 0.05 mm of each other and disposed on opposing sides of the second lateral axis, the first and second inner wire assemblies being in contact with each other at least along various points throughout the length of the flexible jacket; and
first and second outer wire assemblies further extending within the jacket, each of the outer wire assemblies including a wire comprised of a plurality of conductive filaments and an insulating layer consisting essentially of an enamel material surrounding the wire, the jacket maintaining the first and second outer wire assemblies in predetermined positions along the first lateral axis on opposite sides of the second lateral axis and spaced apart from respective adjacent ones of the first and second inner wire assemblies.

2. The connection cable of claim 1 , wherein the enamel material fills spaces between some of the conductive filaments of the outer wire assemblies.

3. The connection cable of claim 1 , wherein the jacket defines a generally rectangular outer profile in a cross-section along a theoretical plane defined by the first and second lateral axes.

4. The connection cable of claim 3 , wherein the jacket further defines first and second minor surfaces, each extending between the first and second major surfaces on respective opposite sides of the second lateral axis, the major surfaces and minor surfaces defining respective portions of the boundary along intersections thereof with the theoretical plane.

5. The connection cable of claim 3 , wherein the jacket continuously fills the cross section in areas within the profile and outside of the inner and outer wire assemblies.

6. The connection cable of claim 1 , wherein the first and second outer wire assemblies are in respective positions that are equidistant from respective outer edges of the jacket and from adjacent outermost portions of inner wire assemblies.

7. The connection cable of claim 6 , wherein the first and second outer wires assemblies are separated from respective closest inner wire assemblies by respective distances of at least 0.5 mm.

8. The connection cable of claim 1 , wherein the first and second major surfaces are spaced apart from respective closest portions of the inner wire assemblies at respective distances of at least 0.5 mm.

9. The connection cable of claim 8 , wherein the inner wire assemblies each have diameters that are substantially equal to each other, and wherein the respective distances between the major surfaces and the inner wires assemblies are equal to the inner wire assembly diameters +/−10%.

10. The connection cable of claim 1 , further including first and second substantially rigid connection elements respectively positioned on opposing ends of the cable jacket, and wherein the cable is generally flexible between the connection elements.

11. The connection cable of claim 1 , wherein the jacket is an extruded composite material including thermoplastic elastomer and silicone.

12. The connection cable of claim 1 , wherein the inner wire assemblies each include respective inner insulator layers inside the shielding layers thereof.

13. The connection cable of claim 1 , wherein the enamel material is a cured epoxy resin.

14. The connection cable of claim 1 , wherein the shielding layer and outer insulating layer comprise discrete layers surrounding each individual wire, such that the shielding layer and outer insulating layers each include a circular cross-section.

15. A connection cable, comprising:
a generally flexible jacket extending along a length thereof and along first and second lateral axes perpendicular to the length thereof, the jacket defining substantially flat first and second major surfaces generally parallel to each other and spaced apart opposite sides of the first lateral axis, and first and second minor surfaces extending between the first and second major surfaces; and
first and second power wire assemblies extending within the jacket, each of the power wire assemblies including an outermost diameter, a wire comprised of a plurality of conductive filaments, and an insulating layer consisting essentially of an enamel material surrounding the wire and filling spaces between some of the conductive filaments thereof, the jacket maintaining the first and second power wire assemblies in predetermined positions along the first lateral axis,
wherein the distance between the outermost diameter of the power wire and the closest minor surface of the flexible jacket is at least about 75 percent of a length of the outside diameter of the power wires.

16. The connection cable of claim 15 , further including:
first and second signal wire assemblies extending within the jacket, each of the signal wire assemblies including a wire comprised of a plurality of conductive filaments, a shielding layer surrounding the wire, and an outer insulating layer surrounding the shielding layer and spaced apart from the wire;
