Abstract
Abstract A signal cable assembly comprising a pair of cables adapted to respectively carry the positive and negative audio signals between a power source and a load. Each cable consists of a first conductor formed by a plurality of bundles of wire strands twisted together to form a single conductor, and a second conductor in the form of a solid conductor having a diameter larger than the diameter of each wire strand. Insulation sleeves extend around the conductors for at least a portion of the length thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
237 words
A signal cable assembly for transferring positive and negative signals between a source and a load, said cable assembly comprising: a first conductor comprising a plurality of bundles of wire strands twisted together and insulation means extending around said bundles of wire strands for a portion of the lengths thereof; a second conductor comprising a plurality of bundles of wire strands twisted together and insulation means extending around said bundles of wire strands for a portion of the lengths thereof; a third conductor comprising at least one solid wire of a diameter greater than the diameter of each of said wire strands, and insulation means extending around said solid wire for a portion of the length thereof; a fourth conductor comprising at least one solid wire of a diameter greater than the diameter of each of said wire strands, and insulation means extending around said solid wire for a portion of the length thereof; said first and third conductors extending in a juxtaposed relationship with their respective axes extending parallel and with their respective uninsulated portions being twisted together to provide a single conductive path for said positive signal; said second and fourth conductors extending in a juxtaposed relationship with their respective axes extending parallel and with their respective uninsulated portions being twisted together to provide a single conductive path for said negative signal; and said second and fourth conductors extending adjacent said first and third conductors.
Claim 2
Dependent Claim
237 words
A signal cable assembly for transferring positive and negative signals between a source and a load, said cable assembly comprising: a first conductor comprising a plurality of bundles of wire strands twisted together and insulation means extending around said bundles of wire strands for a portion of the lengths thereof; a second conductor comprising a plurality of bundles of wire strands twisted together and insulation means extending around said bundles of wire strands for a portion of the lengths thereof; a third conductor comprising at least one solid wire of a diameter greater than the diameter of each of said wire strands, and insulation means extending around said solid wire for a portion of the length thereof; a fourth conductor comprising at least one solid wire of a diameter greater than the diameter of each of said wire strands, and insulation means extending around said solid wire for a portion of the length thereof; said first and third conductors extending in a juxtaposed relationship with their respective axes extending parallel and with their respective uninsulated portions being twisted together to provide a single conductive path for said positive signal; said second and fourth conductors extending in a juxtaposed relationship with their respective axes extending parallel and with their respective uninsulated portions being twisted together to provide a single conductive path for said negative signal; and said second and fourth conductors extending adjacent said first and third conductors.
Claim 3
Dependent Claim
26 words
The signal cable assembly of claim 1 wherein said first conductor extends adjacent said fourth conductor and wherein said third conductor extends adjacent said second conductor.
Claim 4
Dependent Claim
30 words
The assembly of claim 1 wherein the wire strands forming each bundle are twisted in a first direction and the bundles are twisted in a direction opposite said first direction.
Claim 5
Dependent Claim
21 words
The assembly of claim 1 wherein the respective insulated portions of all of said conductors are twisted relative to each other.
Claim 6
Dependent Claim
34 words
The assembly of claim 1 wherein the respective insulated portions of said first and third conductors are molded together and wherein the respective insulation portions of said second and fourth conductors are molded together.
Claim 7
Dependent Claim
25 words
The assembly of claim 1 wherein the diameter of said solid wires are substantially equal to the diameters of said twisted bundles of wire strands.
