Abstract

A shielded cable is disclosed in which a plurality of elongated conductor wires are interwoven with a plurality of metallic fiber strands to define a woven cover for isolating the conductor wires from electromagnetic interference. The woven cover includes a plurality of fiber warp strands woven with a continuous fiber fill strand defining a plain weave of metallic fibers around the conductor wires to shield from external interference and a plurality of warp binder strands woven between adjacent conductor wires between alternate top and bottom runs of the fill strand to shield the conductor wires from internal interference.

Claims

1. A woven shielded cable comprising:

a plurality of elongated conductor wires extending longitudinally in said cable each said wire having a coating of insulation;

a substantially solid outer woven cover formed from metallic fiber strands woven about said conductor wires isolating said wires from external electromagnetic interference;

said woven cover including at least one metallic warp binder strand woven between adjacent conductor wires to separate and shield at least one of said conductor wires between adjacent warp binder strands for reducing internal interference between conductor wires; and

a metallic fill strand woven about said conductor wires and said warp binder strand;

whereby said conductor wires are uniformly shielded from external and internal interference.

2. The shielded cable as set forth in claim 1 wherein said conductor wires are arranged in a generally side-by-side manner to define a substantially flat cable configuration and wherein said woven cover includes a plurality of metallic fiber warp strands woven in a plain weave with said fill strand to form a substantially solid outer cover surrounding said wires for shielding and isolating said conductor wires.

3. The shielded cable as set forth in claim 2 wherein a plurality of said warp binder strands are woven between adjacent conductor wires in an undulating manner between alternate top and bottom runs of said fill strand enhancing uniform shielding of said conductor wires.

4. The shielded cable as set forth in claim 1 wherein said metallic fiber comprises silver plated nylon.

5. The shielded cable as set forth in claim 1 wherein a plurality of said warp binder strands are woven between adjacent conductor wires in an undulating pattern between alternate top and bottom runs of said fill strand with the undulations of adjacent warp binder strands approximately one-hundred and eighty degrees out of phase enhancing the internal shielding of said conductor wires.

6. The shielded cable as set forth in claim 1 wherein said warp binder strand is woven with said fill strand to separate and shield said conductor wires in groups of at least two conductor wires.

7. The shielded cable as set forth in claim 6 wherein a plurality of said warp binder strands are woven between adjacent conductor wire pairs in an undulating pattern between alternate top and bottom runs of said fill strand enhancing shielding of said conductor wires.

8. A woven shielded cable comprising:

a plurality of elongated conductor wires extending longitudinally in said cable each said wire having a coating of insulation;

a plurality of metallic fiber strands interwoven with said conductor wires to define a woven cover for isolating said conductor wires from electromagnetic interference;

said woven cover including a plurality of fiber warp strands and a continuous fiber fill strand woven defining a plain weave of said metallic fibers around said conductor wires to shield said wires from external interference; and

at least a pair of warp binder strands woven between adjacent conductor wires to separate and shield at least one of said conductor wires between adjacent pairs of said warp binder strands; and

said warp binder strands in each said pair being woven in an undulating pattern between alternate top and bottom runs of said fill strand approximately one-hundred and eighty degrees out of phase relative to each other reducing internal interference in said cable;

whereby said conductor wires are effectively shielded from external and internal interference.
