Abstract
Abstract A composite shield jacket and woven electrical transmission cable assembly is disclosed wherein the shield jacket comprises an outer elastomeric cover and a metalized backing on the interior side of the cover which advantageously may comprise a thin flexible fibrous web formed either by weaving metallic coated fibers or forming a non-woven web from the metallic coated fibers, or by applying a thin metallic layer to the backside of the cover. In any case, a highly durable, flexible shield jacket is provided. When the jacket is applied to a flat transmission cable according to the invention, the side edges of the shield are on opposite sides of the cable so as to overlap the sides of the shield and cover so that exits from the shield are defined on opposing sides of the cable reducing the unwanted escape of interference noises. The flexible shield material is terminated by use of a resilient termination element which clips to the shield cloth and is resiliently retained inside a connector housing for termination to a ground plane of the connector. The invention may be applied to a round or tubular cable as well as a flat.
