Abstract
A conductive sheet for shielding electromagnetic waves of this invention has high flexibility in the same direction as a wire. The conductive sheet 10, therefore, is easy to bend along the shape of the wire. Additionally, since conductive sheet 10 preferably maintains its shape in a direction perpendicular to the wire, it is possible to make a conductive link, that is, to make an electrical contact easily, only by applying slight pressure to conductive sheet 10 to change its shape. Moreover, since the metals composing the warp and the weft of the conductive sheet keep the potential difference of the metals below a predetermined voltage at the contact point of both metals, contact corrosion as a practical problem at the predetermined point is eliminated.
Claims18
A conductive sheet for forming a sleeve wrappable around at least one electric wire, for shielding electromagnetic waves from said at least one electric wire comprising:
- a warp running in the axial direction of the at least one electric wire and comprising at least a plurality of coaxial conductive thread strands made from a fibrous substance having flexibility in the axial direction of said strands and said at least one electric wire;
- and
- a weft running in a direction perpendicular to the axis of the wire and the warp, and comprising at least a plurality of metal wires, wherein said warp and said weft are interwoven so as to form a continuous sheet which may be wrapped to form a sleeve around said at least one electric wire.
A conductive sheet for forming a sleeve wrappable around at least one electric wire, for shielding electromagnetic waves from said at least one electric wire comprising:
- a warp running in the axial direction of the at least one electric wire and comprising at least a plurality of coaxial conductive thread strands made from a fibrous substance having flexibility in the axial direction of said strands and said at least one electric wire;
- a weft running in a direction perpendicular to the axis of the wire and the warp, and comprising at least a plurality of metal wires, wherein said warp and said weft are interwoven so as to form a continuous sheet which may be wrapped to form a sleeve around said at least one electric wire;
- and
- two edges of said sheet extending axially of the wire and wherein the sheet is wrapped around the at least one electric wire to provide a substantially cylindrical shield.
A conductive sheet for forming a sleeve wrappable around at least one electric wire, for shielding electromagnetic waves from said at least one electrical wire comprising:
- a warp running in the same axial direction as the at least one electric wire comprising at least a plurality of conductive thread fibers plated with metal;
- a weft running in a direction perpendicular to the at least one electrical wire comprising at least a plurality of metallic wires made from a material which will not cause corrosion when said metallic wires contact the metal of the warp, wherein the warp and weft are interwoven to form a flexible sheet and bendable about the axis of said wire bundle so as to form a substantially cylindrical cross-section;
- fastener means attached to a top and bottom surface of said sheet which engages when said sheet is formed into a cylindrical shape, and when engaged causes said sheet to retain said formed shape, and
- an interconnected means to release electromagnetic waves collected by said sheet.
