Abstract
The present invention is directed to a strong, flexible composite shielding member to provide electromagnetic interference (EMI) shielding between power conductors and signal conductors for use in an electrical transmission system, such as a bundled hybrid cable. A preferred shield member comprises a flat dielectric central laminate having on each major surface thereof a metallic, electrically conductive film, where the core includes a plurality of longitudinally arranged strengthening members, such as fiberglass strands.
Claims14
An electrical transmission system comprising power conductors and signal conductors, and a strong, flexible composite shielding member providing electro-magnetic interference shielding between said power conductors and said signal conductors, where said shielding member comprises a flat dielectric central laminate having on each major surface thereof a metallic, electrically conductive film.
An electrical cable comprising a plurality of electrical conductors and a shield member extending along the length of the cable, the shield member comprising a central laminate member including a plurality of separate, parallel longitudinally extending nonconductive strands, and continuous conductive means adhesively bonded to each side of said central laminate member.
An electrical cable comprising a plurality of electrical conductors and a shield member extending along the length of the cable, the shield member comprising a central laminate member including a plurality of separate, parallel longitudinally extending nonconductive strands and continuous conductive aluminum foil on each side of said central laminate member.
The combination of a pair of planar shielding members arranged in overlapping relationship, where said shielding members are adapted to provide electro-magnetic interference shielding between plural power conductors and plural signal conductors in an electrical transmission system, and each shielding member comprises a flat dielectric central laminate having on each major surface thereof a metallic, electrically conductive film,
- and a metallic splicing member having a generally V-shaped configuration formed by a pair of arms and adapted to receive the overlapping shielding members between said arms, where at least one said arm is provided with at least one inwardly directed lance, whereupon on closing said splicing member the at least one lance is caused to penetrate each said shielding member to effect a strong splice between said shielding members.
