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.
Claims6
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.
