Abstract An arrangement for connection of wiring backplanes and module circuit boards wherein individual contact passages arranged in a housing are surrounded by electrically conductive shielding plates that are connected to contactings that carry shield potential. They are attached in the intermediate grid both at the backplane side as well as at the assembly side, and are charged with a corresponding potential. In order to create a connector arrangement for extremely high transmission frequencies and good transmission properties, terminal ends of spring elements of the sheet metal shielding compartment and terminal ends of the spring elements of shielding plates of the contact passages abut with a contacting layer of precious metal at the backplane side. Both the spring elements of the shielding plates arranged perpendicular to the wiring backplane as well as the spring elements of the shielding compartment proceeding perpendicular to the wiring backplane are corrugated. Terminal lugs are provided on the precious metal layer on the wiring backplane in the cooperating region of the terminal ends. The housing is mechanically secured to the wiring backplane at a plurality of locations.
A system, comprising: a module circuit board; a wiring backplane; a contact housing for connecting the module circuit board to the wiring backplane; said contact housing being formed of a metal shielding compartment, portions of the metal shielding compartment facing toward the wiring backplane having a plurality of zig-zag shaped corrugated spring elements having terminal ends; and the wiring backplane having a metal layer for contacting to and at the terminal ends of said zig-zag-shaped corrugated spring elements.
