Abstract

Abstract A shielded electric cable includes an insulated conductor having an insulating layer on the exterior of a conductor, a drain wire disposed alongside the conductor and spaced therefrom by a predetermined distance, a shielding layer formed by laterally winding shielding material or a net on the exterior of the conductor, a metal tape electrically connecting the shielding layer to the drain wire, and a jacket in which the conductor, the drain wire, and the metal tape are embedded. Electric wires are integrally connected to and spaced a predetermined distance from the conductor and the drain wire at opposite sides thereof, respectively.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 128 words
A shielded electric cable comprising: an insulated conducting member including a conductor and an insulating layer on the exterior of said conductor; a drain wire disposed alongside said conductor and spaced therefrom by a predetermined distance; a shielding layer on the exterior of said conductor; a metal tape electrically connecting said shielding layer to said drain wire; a jacket in which said conductor, said drain wire, and said metal tape are embedded so as to form a cover for them; electric wires disposed alongside said insulated conducting member and said drain wire, said electric wires spaced a predetermined distance from said conductor and said drain wire, respectively, at both sides thereof; and taping means for integrally connecting said electric wires with said insulated conductor and said drain wire.
Claim 2
Dependent Claim 128 words
A shielded electric cable comprising: an insulated conducting member including a conductor and an insulating layer on the exterior of said conductor; a drain wire disposed alongside said conductor and spaced therefrom by a predetermined distance; a shielding layer on the exterior of said conductor; a metal tape electrically connecting said shielding layer to said drain wire; a jacket in which said conductor, said drain wire, and said metal tape are embedded so as to form a cover for them; electric wires disposed alongside said insulated conducting member and said drain wire, said electric wires spaced a predetermined distance from said conductor and said drain wire, respectively, at both sides thereof; and taping means for integrally connecting said electric wires with said insulated conductor and said drain wire.
Claim 3
Dependent Claim 16 words
A shielding cable according to claim 1, wherein said metal tape is an aluminum foil-polyester-laminated tape.
Claim 4
Dependent Claim 24 words
A shielding cable according to claim 1, wherein said jacket is provided with a notch therein at the center of the widthwise direction thereof.
Claim 5
Dependent Claim 48 words
A shielding cable according to claim 1, wherein one end of said metal tape contacts said shielding layer only at half of an exterior circumferential portion thereof and the other end of said metal tape contacts said drain wire only at half of an exterior circumferential portion thereof.
Claim 6
Dependent Claim 25 words
A shielding cable according to claim 1, wherein said metal tape contacts said shielding layer and said drain wire over entire exterior circumferential portions thereof.
