Abstract
A shielded electrical cable that has a set of insulated inner conductors and a shield made of a plurality of insulated wires, arranged about said inner conductors. Each insulated wire of the shield has a conductive core coated by insulation which is fused together with the insulation of the neighboring wires. Also, said conductive cores of said plurality of insulated wires are brought into mutual electrical contact at a longitudinal interval of said twisted shielded pair.
Claims21
A shielded electrical cable, comprising:
- (a) a set of insulated inner conductors;
- (b) a shield made of a plurality of insulated wires, arranged about said inner conductors, each comprising a conductive core coated by insulation and wherein said insulation of said plurality of insulated wires is fused together.
A twisted shielded pair of wires, comprising:
- (a) an inner pair of insulated wires twisted together, said wires having a conductive core made of a material having electrical resistivity of less than 10−7 ohm*m and insulation having an electrical resistivity of greater than 104 ohm*m;
- (b) an outer layer of wires arranged about said inner pair of insulated wires, and wherein said outer layer of wires is held in place by insulation;
- and
- (c) wherein said twisted shielded pair of wires has a diameter of less than 100 microns.
A method of making a shielded electrical cable, comprising:
- (a) providing an insulated set of wires;
- (b) arranging a multiplicity of insulated wires about said insulated set of wires, thereby forming a work piece;
- (c) wherein some insulation of said multiplicity of insulated wires has a first melting point and insulation of said insulated set of wires has a second melting point and wherein said first melting point is lower than said second melting point;
- and
- (d) passing said work piece through an oven set at a temperature between said first melting point and second melting point for long enough for said insulation having a first melting point to soften and fuse together.
