Abstract
Official abstract text for this publication.
A coaxial cable includes a conductor, an insulation layer provided around the conductor, a shield layer provided around the insulation layer, and a sheath provided around the shield layer. The insulation layer includes a first insulation layer, a second insulation layer and a third insulation layer that are arranged in this order from a conductor side. The first insulation layer includes a non-solid extruded layer. The second layer includes a foamed layer not adhering to the first insulation layer. The third insulation layer includes a non-foamed layer adhering to the second insulation layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A coaxial cable, comprising: a conductor; an insulation layer provided around the conductor; a shield layer provided around the insulation layer; and a sheath provided around the shield layer, wherein the insulation layer comprises a first insulation layer, a second insulation layer and a third insulation layer that are arranged in this order from a conductor side, wherein the second layer comprises a foamed layer not adhering to the first insulation layer, wherein the third insulation layer has a larger tensile strength than the second insulation layer, and wherein the third insulation layer is provided to fill air bubble holes appearing on a surface of the second insulation layer. 2. The coaxial cable according to claim 1 , wherein a thickness of the first insulation layer is not more than 0.2 times and not more than 0.3 times a diameter of the conductor. 3. The coaxial cable according to claim 1 , wherein a thickness of the third insulation layer is not less than 1 time and not more than 1.5 times a thickness of the second insulation layer. 4. The coaxial cable according to claim 1 , wherein the shield layer comprises a braided shield formed by braiding tinsel copper wires and metal strands in a crisscross manner. 5. The coaxial cable according to claim 1 , wherein the third insulation layer has a larger elongation than the second insulation layer. 6. A coaxial cable, comprising: a conductor; an insulation layer provided around the conductor; a shield layer provided around the insulation layer; and a sheath provided around the shield layer, wherein the insulation layer comprises a first insulation layer, a second insulation layer and a third insulation layer that are arranged in this order from a conductor side, wherein the second layer comprises a foamed layer not adhering to the first insulation layer, wherein the third insulation layer has a larger tensile strength than the second insulation layer, and wherein a gap is formed between the conductor and the first insulation layer.
