Composite shield jacket for electrical transmission cable
First Claim
1. A shielded electrical transmission cable assembly having improved flexibility and shielding against unwanted electrical noise, emissions and susceptibility said assembly comprising:
- a flat electrical transmission cable having a plurality of insulated longitudinal conductors arranged generally side by side across a width of said cable, said flat cable having a generally planar first side and a generally planar second side defining oppositely facing exterior faces;
an electrical connector member terminating one end of said electrical transmission cable including a housing and a multi-position connector carried by said housing;
a conductive shield cloth wrapped about said electrical transmission cable for conducting unwanted electrical noise;
said shield cloth including a highly flexible fibrous web continuously surrounding and enclosing said flat cable to define a first shield side coplanar and copending across and along the entire first side of said cable, and said fibrous web having a second shield side coplanar and coextending across and along the entire second side of said cable;
said fibrous web having an overlapping edge sealed along its entire length;
a generally flat elastomeric cover bonded to said fibrous web and continuously surrounding said fibrous web and flat cable;
said overlapping edge of said fibrous web being bonded together with said elastomeric cover;
termination means for terminating said shield cloth to said multi-position connector; and
said fibrous web is formed from one of a woven web and non-woven web composed of metalized fibers providing a highly flexible electrical shield jacket with increased durability when secured with said elastomeric cover in said cable assembly.

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.

13. A shielded electrical transmission cable assembly having improved flexibility and shielding against unwanted electrical noise, said assembly comprising:
-
an electrical transmission cable having a plurality of conductors; an electrical connector member terminating one end of said electrical transmission cable including a housing and a multi-position connector carried by said housing; a generally flat integral composite shield jacket surrounding said transmission cable for protecting said cable from abrasion and unwanted electrical noises including a thin outer elastomeric cover; a thin metalized layer in the form a fibrous web consisting of one of a woven web and a non-woven web composed of metalized fibers bonded to a backside of said elastomeric cover for conducting away unwanted electrical noises; said fibrous web entirely surrounding and enclosing said flat cable to define a first shield side coplanar and coextending across and along the entire first side of said cable, and a second shield side coplanar and coextending across and along the entire second side of said cable; said fibrous web having at least one edge bonded together with said backside of said elastomeric cover and sealed along its entire length; and said elastomeric cover having at least one free edge bonded to form a thin flexible seam along a length of said cable assembly so that a flat electrical cable and said composite shield jacket assembly is had with a high degree of flexibility; and termination means for terminating said metalized layer to said multi-position connector. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
