Abstract

A noise suppression cable includes an insulated wire including a conductor and an insulation covering an outer periphery of the conductor, a shield layer formed on an outer periphery of the insulated wire so as to be polygonal in a cross section thereof, an insulation layer formed on an outer periphery of the shield layer so as to be polygonal in a cross section thereof, and a magnetic tape layer formed on an outer periphery of the insulation layer so as to be polygonal in a cross section thereof.

First claim

What is claimed is:

1. A noise suppression cable, comprising:
an insulated wire comprising a conductor and an insulation covering an outer periphery of the conductor;
a first resin tape layer formed around an outer periphery of the insulated wire so as to be polygonal in a cross-section thereof;
a shield layer formed on an outer periphery of the first resin tape layer so as to be polygonal in a cross-section thereof;
a second resin tape layer formed on an outer periphery of the shield layer so as to be polygonal in a cross-section thereof;
a magnetic tape layer formed on an outer periphery of the second resin tape layer so as to be polygonal in a cross-section thereof; and
a third resin tape layer formed on an outer periphery of the magnetic tape layer so as to be polygonal in a cross-section thereof.

2. The noise suppression cable according to claim 1 , wherein a plurality of ones of the magnetic tape layer are formed at a predetermined distance along a cable longitudinal direction.

3. The noise suppression cable according to claim 1 , wherein the polygonal shape comprises a polygon with not less than 5 and not more than 24 sides.

4. The noise suppression cable according to claim 1 , wherein the insulated wire comprises plural insulated wires and wherein fillers are interposed around the plural insulated wires.

5. The noise suppression cable according to claim 1 , further comprising a sheath formed on an outer periphery of the third resin tape layer.

6. The noise suppression cable according to claim 4 , wherein the fillers have different diameters.

7. The noise suppression cable according to claim 1 , wherein the magnetic tape layer is wrapped around the second resin tape layer so as to overlap at both edges thereof, and wherein an overlapping portion of the magnetic tape layer includes joint portions.

8. The noise suppression cable according to claim 1 , wherein at least one of the first, second and third resin tape layers comprises polyethylene terephthalate (PET), a polyethylene tape or a polypropylene-based resin.

9. The noise suppression cable according to claim 1 , wherein at least one of the first, second and third resin tape layers includes a spirally wound resin tape throughout a cable longitudinal direction.

10. The noise suppression cable according to claim 1 , wherein a plurality of ones of the magnetic tape layer are provided, have a predetermined width and are formed around the second resin tape layer at a predetermined distance along a cable longitudinal direction.

11. The noise suppression cable according to claim 1 , wherein the shield layer includes braided conductive wires throughout a cable longitudinal direction.

12. The noise suppression cable according to claim 1 , wherein a width of the magnetic tape layer is 5 mm to 50 mm.

13. The noise suppression cable according to claim 2 , wherein the insulated wire comprises plural insulated wires and wherein fillers are interposed around the plural insulated wires.

14. A noise suppression cable, comprising:
an insulated wire comprising a conductor and an insulation covering an outer periphery of the conductor;
a first resin tape layer formed around an outer periphery of the insulated wire so as to be polygonal in a cross-section thereof;
a shield layer formed on an outer periphery of the first resin tape layer so as to be polygonal in a cross-section thereof;
a second resin tape layer formed on an outer periphery of the shield layer so as to be polygonal in a cross-section thereof;
a magnetic tape layer formed on an outer periphery of the second resin tape layer so as to be polygonal in a cross-section thereof;
a third resin tape layer formed on an outer periphery of the magnetic tape layer so as to be polygonal in a cross-section thereof;
wherein the insulated wire comprises plural insulated wires and wherein fillers are interposed around the plural insulated wires; and
the plural amount of fillers being interposed between the plural insulated wires and the first resin tape layer.

15. The noise suppression cable according to claim 14 , wherein the shield layer includes braided conductive wires throughout a cable longitudinal direction.

16. The noise suppression cable according to claim 14 , wherein a plurality of ones of the magnetic tape layer are provided and wherein a distance between the magnetic tape layers is 5 mm to 50 mm.

17. The noise suppression cable according to claim 14 , wherein the polygonal shape comprises a polygon with not less than 5 and not more than 24 sides.

18. The noise suppression cable according to claim 14 , further comprising a sheath formed on an outer periphery of the third resin tape layer of the magnetic tape layer.

19. The noise suppression cable according to claim 14 , wherein the fillers have different diameters.

20. The noise suppression cable according to claim 14 , wherein the magnetic tape layer is wrapped around the second resin tape layer so as to overlap at both edges thereof, and wherein an overlapping portion includes joint portions.
