Abstract
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.
