ABSTRACT:
An apparatus for providing an electrical connection between an electrical connector and a conductive chassis member includes aligned connector holes in the chassis, a thin ground sheet of springy and conductive material and a thicker support plate. The holes in the thin ground sheet have a periphery that includes alternating gaps and extensions, with the dimension defined by the gaps being larger than the corresponding dimension of the barrel of the electrical connector and the dimension defined by the extensions being smaller than the dimension of the barrel. The thin ground sheet is held in physical and electrical contact with and parallel to the conductive chassis member by the support plate, which is also preferably of conducting material, and a set of screws. When the barrels of electrical connectors associated with a PC board inside of the instrument are made to pass through the aligned apertures in the thicker support plate, the thin ground sheet and the conductive chassis member, respectively, the barrels of the electrical connectors contact the extensions and cause them to bend so that they remain in electrically conducting contact with the barrels of the connectors thereby grounding with connectors to the instrument chassis.
