Abstract
Abstract Connectors are provided for propagation of electrical signals in a plurality of closely spaced propagation paths, such as between circuits connected to conductive pads of circuit boards, each circuit presenting a certain characteristic impedance at a pad connected thereto. For example, each connector includes a plurality of resilient and electrically conductive signal-propagating interconnect means having opposite ends engageable with conductive pads on a pair of the circuit boards. The interconnect means are supported by insulating means of a support structure which also provides conductive ground means in adjacent relation to the conductive interconnect means. The conductive ground means are arranged for connection to grounding elements of the circuit boards. The configuration and characteristics of the ground conductor means and the insulating means in relation to each signal-propagating interconnect means are such as to obtain a certain characteristic impedance for matching the characteristic impedances of circuits interconnected by each signal-propagating interconnect means.
