Abstract
A multi-conductor cable including a plurality of miniature coaxial conductor pairs, each including an inner conductor supported by a very thin tubular layer of solid, relatively stiff dielectic material, surrounded by a much thicker wrapping of dielectric tape having a lower dielectric constant than that of the tubular layer. An outer conductor of multiple strands of wire is helically laid about the dielectric tape wrapping. The tubular layer provides mechanical support for each inner conductor, protecting against breakage due to bending of the individual conductor strands, without significantly increasing either the capacitance or diameter of the coaxial conductor pairs.
