Abstract

A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

First claim

What is claimed is:

1. A cable assembly, comprising:
a shielded electrical cable comprising:
a plurality of differential pairs extending along a length of the cable and being arranged generally in a plane along a width of the cable, each differential pair including two or more insulated conductors and being substantially surrounded by a shield;
first and second non-conductive polymeric layers disposed on opposite sides of the cable, the first and second layers including cover p…
