A shielded electrical cable includes a central conductor wire, a dielectric core over the conductor wire, a metallic foil shielding tape over the dielectric core and an insulated outer jacket over the shielding tape. The shielding tape is wrapped on the dielectric core so that one edge portion of the tape overlaps the opposite edge portion thereof, and it includes a metallic layer and a waterproof adhesive layer on the inner side of the metallic layer. The adhesive layer extends over only preselected portions of the inner side of the metallic layer in the overlapping edge portion of the tape so that a plurality of spaced contact pads are provided on the inner side of the tape wherein the metallic layer is exposed. The adhesive layer bonds and seals the overlapping edge portions of the tape together, and metal-to-metal contact is effected between the inner and outer sides of the metallic layer in the contact pads to reduce radiation leakage between the overlapping edge portions of the tape.
A shielded cable comprising an elongated conductor wire, a dielectric core over said conductor wire, and a metallic shielding tape over said core, said shielding tape having opposite longitudinally extending first and second edge portions adjacent opposite longitudinally extending first and second edges thereof, respectively, said shielding tape being wrapped over said core so that the second edge portion of said tape overlaps the first edge portion thereof, said tape comprising a metallic layer extending substantially across the width of said tape and having substantially smooth inner and outer metallic surfaces, and an adhesive layer preprinted on preselected portions of the inner surface of said metallic layer in said second edge portion to define a plurality of localized metallic contact pads thereon where the inner surface of said metallic layer is not coated by said adhesive layer, the outer surface of said metallic layer substantially defining the outer surface of said tape in said first edge portion, said adhesive bonding said second edge portion to said first edge portion, the inner surface of said metallic layer contacting the outer surface of said metallic layer in at least a portion of said contact pads.
