Device arrangement with a structural component mounted in a housing

A device arrangement comprising:

• a housing (14), with an opening (60) and a cover panel (56, 156) for closing the opening, and
• a subassembly (10) which is retained in a releasable manner in the housing (14) on an installation wall (12, 112), the subassembly (10) being suspended on the installation wall (12, 112) by means of a hook-like mounting element (36) and being retained in its position by the cover panel (56, 156), the cover panel (56, 156) and the housing (14) each having at least a sub-region comprised of an electrically conductive or conductively coated material, and, in the above-mentioned retained position of the subassembly in the housing, an electrical connection being produced between the subassembly (10) and the housing (14) with the aid of the cover panel (56, 156),
• the installation wall (12, 112) having a mounting edge (46, 146) in the vicinity of the opening (60),
• in the retained condition of the subassembly (10) the mounting element (36) being provided on a side of the subassembly (10) which is directed toward the installation wall (12, 112), with the installation wall (12, 112) having a channel (38) which receives the mounting edge (46, 146),
• there being arranged on the subassembly (10), beneath the mounting element (36), a supporting element (30) which, in the retained position of the subassembly (10), butts against the installation wall (12, 112), and
• the cover panel (56, 156) in a closed position relative to the housing in which it closes the opening (60) subjecting the subassembly (10) to an elastic pressure-exerting torque which presses the supporting element (30) against the installation wall (12, 112).
