ABSTRACT:
First and second arrays of easily mated coaxial connectors are provided, which are of compact construction to enable efficient transmission of very high frequencies and in a compact arrangement. The outer conductor (22, FIG. 5) of a first connector (1) includes a male outer contact part (44) which is received in a female outer contact part (46) of the second connector, which leaves a step (70) where the inside surface of the male contact part is smaller than that of the adjacent female contact part, thereby creating a capacitive discontinuity. The front ends (74, 76) of the dielectric members (24, 34) of the first and second connectors are slightly axially spaced apart to leave a gap (72) between them. The gap produces an inductance that cancels the effect of the capacitance created by the step, to minimize insertion and return losses. The fact that the compensating gap and step are present avoids the need for a butt interface of the outer conductors. This enables simple and therefore low cost and compact construction for the connectors.
