Mechanische Verbindung zwischen Seitenwänden und Rückwand eines Blechgehäuses

摘要

To produce mechanical links without additional measures the invention provides for the base (1), side walls (2) and rear wall (3) of a sheet casing to consist of a single, common piece of sheet. The side walls each have an incision (4) in the area of their upper rear corner and the rear wall has a bent edge (5) which on its sides presents hook-like projections (6). When the rear wall itself is folded upwards these click into place in the incision of the side walls.
