Abstract:
1. An electrical connector jack having a free end and a fixed end comprising: an inner conductor of a coaxial cable having an outer diameter and a free end, an outer conductor of said coaxial cable having an inner diameter and a free end, said inner conductor coaxial with said outer conductor, said inner and outer conductor free ends coincident with said connector jack free end, said inner conductor free end projecting beyond said outer conductor free end; said fixed end attachable to said coaxial cable having a dielectric spacer between said inner and outer conductors, and extending up to said outer conductor free end; an electrically conductive cap substantially covering said inner conductor free end projected beyond said outer conductor free end, said cap coaxial with said inner conductor, substantially cylindrical, and having an inner diameter substantially equal to said inner conductor outer diameter, and having an outer diameter slightly larger than said inner conductor outer diameter; said connector jack engaging and electrically connected with a coaxial mating plug having corresponding inner and outer conductors and at least dielectric spacer therebetween; and wherein the inner and outer conductors of said connector jack and said mating plug are shaped, and material for the dielectric spacers is chosen, such that when said connector jack is engaged with said mating plug, along the central axis of the engaged connection the effective outer diameter of the inner conductor referenced by “d”, the effective inner diameter of the outer conductor referenced by “D”, and a relative dielectric constant of the medium therebetween referenced by ε, satisfy the equation: where “Z” is the impedance, and the impedance is substantially constant throughout the central axis of said engaged connection.
