Abstract A flexible, sealed, non-inflammable, low-weight, non-extensible conductive wire having great tensile and bending strength and resistance to friction comprising a core material composed of a very good conductor of electricity, this core material being electrically insulated; a sheath comprising a bundle of metallic wires that are either conductive or may be made conductive, this sheath having high strength; and a protective envelope comprising at least one coating layer. This high-strength, low-weight, nonextensible conductive wire is particularly well adapted for use in the remote control of rockets or in other applications where resistance to high temperature and high stress is necessary.
The conductive wire of claim 1 wherein said good conductor of electricity is a copper wire and said insulator surrounding said good conductor is enamel.
Claim 2
Dependent Claim
13 words
The conductive wire of claim 1 wherein said sheathing wires are high-strength steel.
Claim 3
Dependent Claim
13 words
The conductive wire of claim 2 wherein said sheathing wires are high-strength steel.
Claim 4
Dependent Claim
35 words
The conductive wire of claim 1 wherein said protective covering comprises at least two thin coatings with the outermost coating comprising a heat-sealing composition selected from the group consisting of vinyl polymers and vinyl copolymers.
Claim 5
Dependent Claim
35 words
The conductive wire of claim 4 wherein said protective covering comprises at least two thin coatings with the outermost coating comprising a heat-sealing composition selected from the group consisting of vinyl polymers and vinyl copolymers.
Claim 6
Dependent Claim
32 words
The conductive wire of claim 4 wherein said textile yarn is wound around said high-strength metallic sheaThing wires with a twist the reverse of that of said sheathing wires around said core.
Claim 7
Dependent Claim
32 words
The conductive wire of claim 6 wherein said textile yarn is wound around said high-strength metallic sheathing wires with a twist the reverse of that of said sheathing wires around said core.
Claim 8
Dependent Claim
25 words
The conductive wire of claim 8 wherein the turns of said helically wound textile yarn are substantially parallel to the direction of said core wire.
Claim 9
Dependent Claim
24 words
The conductive wire of claim 7 wherein the turns of said helically wound textile yarn are substantially parallel to the direction of said core.
