Abstract

An electrical connector provides both electrically conductive connection and inductive connection, and includes at least one electrically conductive member adapted to provide electrically conductive connection to another electrically conductive member, an inductive electrical member adapted to provide inductive coupling with another inductive electrical member, and wherein the at least one electrically conductive member and the inductive electrical member being held in positional relation to each other to be positioned with respect to a further electrical connector for electrically conductive connection and inductive coupling with respect thereto. A method of connecting electrical signals uses a pair of electrical connectors, each having an electrically conductive connection portion and an inductive connection portion to provide for both electrically conductive connection and inductive coupling between the electrical connectors.
