Abstract

Abstract An interboard connector for microwave and high-speed circuitry applications such as, for example, employed in computer technology. A solid conductive block is provided with at least one notch for receiving a substantially C-shaped conductive member having one or more strips of insulation material along its interior surface. The insulation material provides a tri-plate structure bent to conform to the C-shaped configuration of the Cshaped conductive member which is force-fitted into the notched block. The tri-plate structure extends from a pair of openings and its ends each adapted to receive and be electrically connected with cooperating edges of a pair of printed wiring boards which are typically provided with a ground plane separated from printed wiring by an intermediate insulating substrate. The arrangement permits simple and yet rapid interconnection between circuit boards and provides excellent impedance matching and a low VSWR. Either one or a plurality of pairs of such tri-plate structures may be provided for connecting circuit boards arranged in spaced substantially parallel fashion.
