Abstract

A flat multiconductor electrical cable assembly is disclosed. The cable assembly includes a plurality of electrical conductors surrounded in an insulative casing. An insulative sheet overlies the insulative casing and separates a wire mesh ground shield therefrom. An outer cover encloses the entire cable assembly. The insulative sheet is easily strippable from the insulative casing by use of a release strip along one longitudinal edge thereof. This facilitates stripping of the cable by providing non-adhesived area between the insulative sheet to the casing.

Claims

1. A shielded electrical cable assembly comprising:

a plurality of elongate, spaced electrical conductors;

an elongate electrically insulative casing surrounding and electrically isolating said conductors;

an elongate electrically conductive shield overlying said casing;

an elongate cover overlying said shield, and

an elongate insulative sheet disposed between said shield and said casing adhesively bonded on one side of said insulative sheet through said shield to said cover and bonded directly to said casing on the other side, said insulative sheet including along one longitudinal edge on said other side, a continuous release strip for providing a non-bonded relation between said insulative sheet and said casing to facilitate stripping of said casing from said assembly.

2. An assembly of claim 1 wherein said release strip is disposed along both longitudinal edges of said insulative sheet.

3. An assembly of claim 1 wherein said release strip comprises a coating of a release agent on said insulative sheet.

4. An assembly of claim 3 wherein said insulative sheet is polyester.

5. An assembly of claim 4 wherein said release agent is formed of polyvinylchloride.

6. An assembly of claim 4 wherein said conductive shield is a wire mesh.

7. An assembly of claim 6 wherein the entire one side of said insulative sheet is coated with adhesive.

8. An assembly of claim 6 wherein one of said conductors is exposed from said casing and is positioned in intimate contact with said wire mesh.
