SHIELDED CABLE
A shielded cable includes an electric wire bundle configured such that a plurality of electric wires are bundled, a first band-shaped member configured to be spirally wound so as to cover the electric wire bundle, a second band-shaped member configured to be spirally wound on the outer periphery of the first band-shaped member, and a drain wire configured to be arranged between the first band-shaped member and the second band-shaped member. The first band-shaped member and the second band-shaped member include a metal layer including a conductive metal and a resin layer including an insulating resin, and are wound such that the metal layers thereof face each other across the drain wire. The first band-shaped member, the second band-shaped member and the drain wire are wound in the same direction to the electric wire bundle.
1 . A shielded cable, comprising:
an electric wire bundle configured such that a plurality of electric wires are bundled;
a first band-shaped member configured to be spirally wound so as to cover the electric wire bundle;
a second band-shaped member configured to be spirally wound on the outer periphery of the first band-shaped member; and
a drain wire configured to be arranged between the first band-shaped member and the second band-shaped member,
wherein the first band-shaped member and the second band-shaped member comprise a metal layer comprising a conductive metal and a resin layer comprising an insulating resin and are wound such that the metal layers thereof face each other across the drain wire, and
wherein the first band-shaped member, the second band-shaped member and the drain wire are wound in a same direction relative to the electric wire bundle.
2 . The shielded cable according to claim 1 , wherein the first band-shaped member and the second band-shaped member have a same width, and
wherein the first band-shaped member, the second band-shaped member and the drain wire are wound at a same pitch.
3 . The shielded cable according to claim 1 , further comprising a tape member comprised of an insulating resin that is configured to be spirally wound between the electric wire bundle and the first band-shaped member in a same direction as that of the first band-shaped member.
4 . The shielded cable according to claim 1 , wherein the drain wire comprises an assembled twisted wire of copper or a copper alloy.
5 . The shielded cable according to claim 1 , wherein the drain wire has a cross-sectional area that is equal to that of a center conductor of at least any one of the plurality of the electric wires.
6 . The shielded cable according to claim 1 , wherein the first band-shaped member and the second band-shaped member are configured such that the metal layer has a thickness of 7 to 9 μm and the resin layer has a thickness of 4 to 6 μm.
7 . The shielded cable according to claim 1 , wherein the first band-shaped member and the second band-shaped member are configured such that the metal layer comprises aluminum or an aluminum alloy.
8 . The shielded cable according to claim 1 , wherein the first band-shaped member and the second band-shaped member are configured such that the metal layer comprises copper or a copper alloy.
