Abstract:
A quad electrical signal cable having a central axis and a length, comprising:a) four electrical conductors of substantially equal length disposed lengthwise within said cable, said four electrical conductors associated as two each in two pairs;b) a positioner disposed within said cable and extending along a substantial portion of the length of said cable, said positioner formed of a substantially insulating material;c) said two pairs of conductors disposed by said positioner within the cable such that said conductors occupy radial positions substantially equidistant from said central axis, and each conductor of a pair occupying a diametrically opposite position from the other conductor of the pair, said pairs substantially subtending an angle of 90 degrees with respect to each other and further having a helical twist throughout a substantial portion of the length of said cable, whereby substantially spiral and orthogonal electrical signal paths throughout said length of said cable are formed;d) such that the material forming said positioner is selected from the group consisting of thermally moldable plastic materials having substantially low dielectric constants and low dielectric losses;e) said positioner centered about said central axis and further having an outer diameter greater than twice a radial distance from said central axis to a radially outermost extent of said conductors,such that said positioner includes four longitudinal insulating and positioning members generally extending said length of said cable, each having a substantially similar quadrant cross section, each containing at least two aperture spaces, each aperture space located on two respective radial surfaces, and such that a conjunction of the four members retains said four conductors in respective ones of a set of four spaces formed by a pairwise conjunction of the eight said aperture spaces.
