Shielding tape with multiple foil layers
First Claim
1. A cable comprising:
- (a) a first center conductor;
(b) a second center conductor;
(c) a third center conductor;
(d) a fourth center conductor;
(e) a first pre-manufactured flexible shielding tape surrounding the first center conductor and the second center conductor, the first shielding tape comprising;
(i) a first shielding layer bonded to a first separating layer;
(ii) a second shielding layer bonded to the first separating layer and a second separating layer; and
(iii) a third shielding layer bonded to the second separating layer, wherein the first, second, and third shielding layers individually comprise a metal;
(f) a second shielding tape surrounding the third center conductor and the fourth center conductor, the second shielding tape comprising;
(i) a first shielding layer bonded to a first separating layer;
(ii) a second shielding layer bonded to the first separating layer and a second separating layer; and
(iii) a third shielding layer bonded to the second separating layer; and
(g) an adhesive applied to each of the third shielding layers, the adhesive for attaching each of the shielding tapes to a component of the cable, wherein the cable is an RG6-type coaxial cable.

Abstract
A coaxial cable of the present invention comprises a center conductor, a dielectric surrounding the center conductor, a shielding tape surrounding the dielectric, a braided metal surrounding the shielding tape, and an outer jacket surrounding the braided metal. The shielding tape comprises: (i) a first shielding layer bonded to a first separating layer; (ii) a second shielding layer bonded to the first separating layer and a second separating layer; and (iii) a third shielding layer bonded to the second separating layer. The present invention eliminates the potential problem of the outer shielding structures separating and interfering with connector attachment. Furthermore, the use of three or more shielding layers in the shielding tape of the present invention improves the flex life of the shield tape by covering micro-cracks in the metal layers with additional shielding layers, thus reducing signal egress or ingress. Accordingly, the present invention provides cost savings and/or an improvement in shielding performance.
