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
