Claims
- 1. Electronic device with a housing (1), a rear wall (7) and accommodated in the housing at least one printed circuit board (10) which stands essentially perpendicular to the rear wall,characterized in that the rear wall (7) is a part independent of the housing (1), with which components (20) to be cooled are in thermal contact and which part closes off the interior of the housing to the rear and wherein the printed circuit board (10) is connected in a bearing manner to the rear wall (7) by holding means (13, 15) protruding from the rear wall (7) and engaging with the printed circuit board (10), and the rear wall (7) having at least two hook elements on its outer side for suspension on a mounting rail and at least one releasable retaining element (19) below the hook elements (17) which engages with the mounting rail.
- 2. The device of claim 1, characterized in that the holding means comprise webs (13) which penetrate recesses (14) of the printed circuit board (10) and are capable of being clinch-connected.
- 3. The device of claim 1, characterized in that the holding means comprise alignment pins (15) allocated to bores (16) of the printed circuit board (10).
- 4. The device of claim 1, characterized in that the rear wall (7) comprises an outer plate (7z) and an inner plate (7i), wherein the inner plate comprises regions (12) which are at a distance from the outer plate and from which the holding means (13, 15) protrude.
- 5. The device of claim 4, characterized in that the inner plate (7i) is partially in contact with the outer plate (7a) and has regions (12) running essentially parallel to and at a distance from the outer plate.
- 6. The device of claim 5, characterized in that at least the inner plate (7i) consists of metal.
- 7. The device of claim 4, characterized in that the inner plate (7i) is made of metal.
- 8. The device of claim 2, characterized in that components (20) to be cooled are in contact with the inner plate (7i) of the rear wall (7).
- 9. The device of claim 1, characterized in that the housing (1) is made of synthetic material.
- 10. Electronic device with a housing (1), a rear wall (7) and accommodated in the housing at least one printed circuit board (10) which stands essentially perpendicular to the rear wall,characterized in that the rear wall (7) is a part independent of the housing (1), with which components (20) to be cooled are in thermal contact and which part closes off the interior of the housing to the rear and wherein the printed circuit board (10) is connected in a bearing manner to the rear wall (7) by holding means (13, 15) protruding from the rear wall (7) and engaging with the printed circuit board (10) and the components (20) to be cooled being pressed with the assistance of U-shaped holding springs (21) against the rear wall (7) or its inner plate (7i), wherein the feet of the holding springs penetrate apertures (22) of the rear wall (7) and their web-parts are in contact with the component.
- 11. The device of claim 10, characterized in that the holding means comprise webs (13) which penetrate recesses (14) of the printed circuit board (10) and are capable of being clinch-connected.
- 12. The device of claim 10, characterized in that the holding means comprise alignment pins (15) allocated to bores (16) of the printed circuit board (10).
