Abstract

According to the present invention, a shielded electrical cable comprises an outer layer of insulating material surrounding a signal conductor and an associated ground conductor and a common shielding layer in electrical contact with the ground conductor but separated from the signal conductor by an inner layer of insulating material surrounding the signal conductor, the signal and ground conductors extend in spaced parallel relationship in a common plane, each surrounded by an individual outer layer of insulating material, the two outer layers of insulating material being integrally formed with a web extending between the two outer layers of insulating material, the shielding layer extending about the inner layer of insulating material on the signal conductor, through the web, and about the ground conductor.

Dependent claims

A shielded electrical cable, comprising:

a plurality of signal conductors;
a sheath of insulating material surrounding each of the signal conductors defining insulated signal conductors;
a plurality of ground conductors, the insulated signal conductors and the ground conductors being alternately arranged in spaced parallel relationship as a planar array;
a layer of shielding material substantially surrounding and electrically engaging each of the ground conductors and defining shield-engaging ground conductors, said layer of shielding material extending to an adjacent one of the insulated signal conductors and substantially surrounding the adjacent one of the insulated signal conductors;
and
an outer layer of insulating material surrounding each of the shielded insulated signal conductors, each of the shield-engaging ground conductors, and the shielding material extending between adjacent signal conductors and ground conductors, the insulating material covering both sides of the layer of shielding material extending between adjacent signal conductors and ground conductors and defining a web.
