Abstract: An electrically conductive contact for electrically connecting an insulated conductor to an electrically conductive track of a printed circuit board, including bifurcate contact arms extending from a common section of the contact, an open end section of the contact arms being adapted to receive an end section of the insulated conductor, pierce the insulation and effect electrical connection therewith; and a fastener for electrically coupling the contact to the track of the printed circuit board, wherein the arms include torsion inhibitors for resiliently inhibiting movement of the arms about respective axes when the insulated conductor is forced therebetween.

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.
