Abstract
Abstract In an electrical cable comprising a plurality of conductors extending in a spaced parallel relationship in a common plane surrounded by outer layers of insulating material joined by web portions, certain conductors are surrounded by inner layers of insulating material which are in turn surrounded by individual foil shielding layers, the shielding layers being interconnected and connected to at least one other conductor by a shielding connection member in the form of a foil which extends through the web portions of the cable.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
236 words
A shielded electrical cable, comprising: a plurality of coaxial cables, each of the coaxial cables including a signal conductor, an insulating sheath surrounding the signal conductor and an outer conductor surrounding the insulation sheath; a ground conductor extending in the same direction as said coaxial cables with the coaxial cables and the ground conductor being disposed in a substantially planar array; an outer layer of insulating material covering the coaxial cables and the ground conductor thereby maintaining the coaxial cables and the ground conductor in ribbon form and defining web means between the respective coaxial cables and the ground conductor so that the coaxial cables and the ground conductor remain parallel and spaced with respect to one another; electrical conductive means disposed within the outer layer of insulating material, electrically engaging respective outer conductors of the coaxial cables therealong, extending through the web means and electrically engaging the ground conductor thereby electrically connecting all of the outer conductors of said coaxial cables to said ground conductor; and the diameter of the outer layer of insulating material surrounding the ground conductor being substantially the same as the insulation sheath surrounding each signal conductor so that exposed insulation sheaths containing the signal conductors therein and the insulated ground conductor can be mass terminated in terminating sections of electrical terminals positioned at spaced intervals in a housing member corresponding to the spacing between the signal conductors and ground conductor.
Claim 2
Dependent Claim
236 words
A shielded electrical cable, comprising: a plurality of coaxial cables, each of the coaxial cables including a signal conductor, an insulating sheath surrounding the signal conductor and an outer conductor surrounding the insulation sheath; a ground conductor extending in the same direction as said coaxial cables with the coaxial cables and the ground conductor being disposed in a substantially planar array; an outer layer of insulating material covering the coaxial cables and the ground conductor thereby maintaining the coaxial cables and the ground conductor in ribbon form and defining web means between the respective coaxial cables and the ground conductor so that the coaxial cables and the ground conductor remain parallel and spaced with respect to one another; electrical conductive means disposed within the outer layer of insulating material, electrically engaging respective outer conductors of the coaxial cables therealong, extending through the web means and electrically engaging the ground conductor thereby electrically connecting all of the outer conductors of said coaxial cables to said ground conductor; and the diameter of the outer layer of insulating material surrounding the ground conductor being substantially the same as the insulation sheath surrounding each signal conductor so that exposed insulation sheaths containing the signal conductors therein and the insulated ground conductor can be mass terminated in terminating sections of electrical terminals positioned at spaced intervals in a housing member corresponding to the spacing between the signal conductors and ground conductor.
Claim 3
Dependent Claim

A shielded electrical cable as set forth in claim 1, wherein the signal and ground conductors are substantially the same size.
Claim 4
Dependent Claim
21 words
A shielded electrical cable as set forth in claim 1, wherein the outer conductors and electrical conductive means are metal foils.
