Abstract

A shielded cable includes at least one electric wire or cable, a shield being provided around the at least one electric wire or cable and including a plurality of wires comprising a metal material, an insulating coating being provided around the shield in direct- and plane-contact with the plurality of wires. The insulating coating includes a base resin composed of acid-modified fluoropolymer, and a heat-dissipating filler included in the base resin. The heat-dissipating filler is electrically insulating and has at least one functional group of NH 2 group and OH group on its surface.

Claims (28)

1. A shielded cable, comprising:

at least one electric wire or cable;

a shield being provided around the at least one electric wire or cable and comprising a plurality of wires comprising a metal material;

an insulating coating being provided around the shield in direct- and plane-contact with the plurality of wires; and

a recessed space being provided between the insulating coating and the wires adjacent to each other,

wherein the insulating coating comprises a base resin comprising an acid-modified fluoropolymer, and a heat-dissipating filler being included in the base resin, the heat-dissipating filler being electrically insulating and having at least one functional group of NH2 group and OH group on its surface, and

wherein the insulating coating enters the recessed space between the wires adjacent to each other.

2. The shielded cable according to claim 1 , wherein the heat-dissipating filler is composed of one or more of a boron nitride filler, an aluminum nitride filler, a silicon carbide filler, a zinc oxide filler, and an alumina filler.

3. The shielded cable according to claim 2 , wherein the heat-dissipating filler is composed of the boron nitride filler and/or the aluminum nitride filler.

4. The shielded cable according to claim 1 , wherein the acid-modified fluoropolymer is an acid-modified PFA, ETFE, or FEP.

5. The shielded cable according to claim 1 , wherein the acid-modified fluoropolymer is an acid-modified PFA and the heat-dissipating filler is a boron nitride filler.

6. The shielded cable according to claim 1 , wherein a concentration of the heat-dissipating filler in the insulating coating is 2 mass % or more and 12 mass % or less.

7. The shielded cable according to claim 1 , wherein a major axis of the heat-dissipating filler is 50 nm or more and 1 μm or less.

8. The shielded cable according to claim 1 , wherein the at least one electric wire or cable comprises two or more electric wires and/or cables in total.

9. The shielded cable according to claim 8 , wherein the two or more electric wires and/or cables includes an insulator.

10. The shielded cable according to claim 1 , wherein the wires adjacent to each other are in contact with each other.

11. The shielded cable according to claim 1 , wherein the shield is a spiral shield including the wires being spirally wound.

12. A shielded cable, comprising:

at least one electric wire or cable;

a shield being provided around the at least one electric wire or cable and comprising a plurality of wires comprising a metal material;

an insulating coating being provided around the shield; and

a recessed space being provided between the insulating coating and the wires adjacent to each other,

wherein the insulating coating comprises a base resin comprising an acid-modified fluoropolymer, and a heat-dissipating filler being included in the base resin, the heat-dissipating filler being electrically insulating and having at least one functional group of NH2 group and OH group on its surface,

wherein the wires adjacent to each other are in contact with each other, and

wherein the insulating coating enters the recessed space between the wires adjacent to each other.

13. The shielded cable according to claim 12 , wherein the shield is a spiral shield including the wires being spirally wound.

14. The shielded cable according to claim 12 , wherein the at least one electric wire or cable comprises two or more electric wires and/or cables in total, and

wherein the two or more electric wires and/or cables includes an insulator.
