Abstract

Abstract A subassembly case (2) including a sheet metal shield (10) consisting of electrically conductive material, having venting holes (12), and being supported by recessed shoulders (18,20) on front and rear members (6, 8) of the subassembly case (2) to which it is detachably connected. The sheet metal shield (10) is flat and provided with holes of rectangular shape which are arranged in two rows (28, 30) and with their short sides (32) next to each other along a bearing area (14, 16) of the sheet metal shield (10). The sheet metal shield (10) is connected to the shoulders (18, 20) of the members (6, 8) by means of V-shaped fastening spring clips (34) each consisting of electrically conductive material and provided with lateral projections (36). In the snapped-in position of the fastening spring clips (34), the leg (40) of each fastening spring clip (34), designed as a detent hook (42), grips behind the respective shoulder (18, 20) of the front and rear members (6, 8). A sheet metal shield (10) is thus obtained whose storage or transport volume is substantially reduced and which can be detachably joined to the members (6,8) of the subassembly case (2) without additional holes in subassembly case parts.
