Abstract
Official abstract text for this publication.
A cable is composed of a cable core including one or more electric wires, a shield layer covering around the cable core, and a sheath covering around the shield layer. The shield layer includes a braided shield braided in such a manner that first metal wires composed of aluminum or an aluminum alloy intersect with second metal wires composed of copper or a copper alloy. An outer diameter of each of the second metal wires is larger than an outer diameter of each of the first metal wires.
First claim
Opening claim text (preview).
The invention claimed is: 1. A cable comprising: a cable core including one or more electric wires; a shield layer covering around the cable core; and a sheath covering around the shield layer, wherein the shield layer comprises a braided shield braided in such a manner that first metal wires composed of aluminum or an aluminum alloy intersect with second metal wires composed of copper or a copper alloy, and wherein an outer diameter of each of the second metal wires is larger than an outer diameter of each of the first metal wires, wherein the cable core includes an inner shield layer covering around the one or more electric wires and being provided inside the shield layer, and the inner shield layer comprises a braided shield braided in such a manner that third metal wires composed of aluminum or an aluminum alloy intersect with fourth metal wires composed of copper or a copper alloy, and wherein an outer diameter of each of the third metal wires is larger than an outer diameter of each of the fourth metal wires, wherein the outer diameter of each of the second metal wires is larger than the outer diameter of each of the fourth metal wires, and wherein the outer diameter of each of the first metal wires and the outer diameter of each of the third metal wires are larger than the outer diameter of each of the fourth metal wires but smaller than the outer diameter of each of the second metal wires. 2. The cable according to claim 1 , wherein a braided density of the shield layer is 85% or more and a braided density of the inner shield layer is 85% or more. 3. The cable according to claim 1 , wherein the one or more electric wires comprises plural electric wires that are arranged between the inner shield layer and the shield layer. 4. The cable according to claim 1 , wherein the cable core includes a signal line for signal transmission and a power supply line for power supply as the one or more electric wires. 5. A cable comprising: a cable core including one or more electric wires; a shield layer covering around the cable core; and a sheath covering around the shield layer, wherein the shield layer comprises a braided shield braided in such a manner that first metal wires composed of aluminum or an aluminum alloy intersect with second metal wires composed of copper or a copper alloy, and wherein an outer diameter of each of the second metal wires is larger than an outer diameter of each of the first metal wires, wherein the cable core includes an inner shield layer covering around the one or more electric wires and being provided inside the shield layer, and the inner shield layer comprises a braided shield braided in such a manner that third metal wires composed of aluminum or an aluminum alloy intersect with fourth metal wires composed of copper or a copper alloy, and wherein an outer diameter of each of the third metal wires is larger than an outer diameter of each of the fourth metal wires, and wherein the outer diameter of each of the first metal wires and the outer diameter of each of the third metal wires are equal to each other.
