Compensated interface coaxial connector apparatus

A coaxial connection apparatus which includes first and second mateable coaxial connectors that each have an axis with said axes lying substantially coincident when said connectors mate, with said first connector having first inner and outer conductors and a first dielectric member therebetween and said second connector having second inner and outer conductors and a second dielectric member therebetween, characterized by:

• said first outer conductor forms a male outer contact part with an inside, and said second outer conductor forms a female contact part with an inside that receives and is engaged with said male contact part, with said male contact part having a front end of smaller inside diameter than that of a location on the inside of said female part that lies around said front end of said male contact part;
• said first and second dielectric members have front ends that lie close to each other when said connectors mate, but with an axially extending gap between them;
• the inside of said female contact part has a greater diameter at said gap than the inside of said male contact part at said gap;
• and
• the axial length of said gap is about 8% of the inside diameter of said male contact part at said gap, and the inside diameter of said female contact part at said gap is about one-third greater than the inside diameter of said male contact part at said gap.

A coaxial connection apparatus which includes an array of substantially identical first jack connectors, an array of substantially identical second plug connectors, and apparatus for holding said arrays of first and second connectors to simultaneously mate and unmate pairs of said connectors, with each of said connectors having an axis and with the axis of each of said first connectors lying substantially coincident with an axis of a mating one of said second connectors when said connectors mate, with said first connectors each having first inner and outer conductors and a first dielectric member therebetween and with said second connectors each having second inner and outer conductors and a second dielectric member therebetween, characterized in that for each pair of mating connectors:

• the first outer conductor of the pair forms a male outer contact part with an inside, and the second outer conductor of the pair forms a female contact part with an inside that receives and is engaged with the male contact part, with the male contact part having a front end of smaller inside diameter than that of a location on the inside of the female contact part that lies around said front end of the male contact part;
• the first and second dielectric members of the pair have front ends that lie close to each other when the pair of connectors mate, but with an axially extending gap between them;
• the inside of the female contact part of the pair has a greater diameter at the gap than the inside of the male contact part of the pair at the gap;
• and
• for said pairs of mating connectors of said arrays of connectors, the gaps between the front ends of said dielectric members have an average axial length that is about a predetermined value A, and the female contact parts of the plug connectors have inside diameters D2 at said gaps that are greater than the inside diameters D1 of the male contact parts at said gaps, by about four times the average axial length of said gaps.

A coaxial connection apparatus comprising:

• a plurality of first coaxial connectors that each includes an axis, a first inner conductor with a front end, a first outer conductor with a front end, and a first insulator with a front end, the front end of the first inner conductor and the front end of the first outer conductor of each of said first connectors forming a space between them, with said first insulator of each of said connectors occupying substantially all of said space;
• a plurality of second coaxial connectors that each includes an axis, a second inner conductor with a front end, a second outer conductor with a front end, and a second insulator with a front end that occupies substantially all of the space between the front ends of said second inner and outer conductors;
• apparatus that holds said pluralities of first and second connectors mated, wherein one of said inner conductors of each of said first connectors is engaged with one of said inner conductors of each of said second connectors and one of said outer conductors of each of said first connectors is engaged with one of said outer conductors of each of said second connectors and said front ends of said insulators of said first and second connectors lie close to each other;
• said first outer conductors lie within said second outer conductors so there is a step in the diameters of their inner surfaces at the front ends of said first outer conductors, and said apparatus holds said connectors so there is an axial space between the extreme front ends of substantially all of said first and said second insulators;
• and
• said axial spaces have an average axial length that is between 0.002 inch (0.05 mm) and 0.010 inch (0.25 mm), and the outside diameters of the front ends of said second insulators are between 10% and 90% greater than the outside diameters of the front ends of said first insulators.
