Date Sep. 29, 1994The invention relates to a connecting rear wall (10) for subracks in electronic systems. Metal plates (14, 16) are mounted parallel to a wiring board (12) by being screwed thereto and simultaneously serve to feed the supply voltages and to screen high-frequency interferences. Cutouts (26) and openings (A) in the metal plates (14, 16) have a maximum dimension which does not exceed +E,fra 1/10+EE to +E,fra 1/20+EE of the wavelength of the interference signal of highest frequency which is to be screened.
