Abstract: In a control device the printed circuit board (10) rests on a rim (28) of the housing bottom (26). The power components (14) to be cooled are arranged in the area where the printed circuit board (10) rests on the rim (28). In order to achieve an even contact pressure of the printed circuit board (10) over the entire support surface, a contact pressure on the power component (14) or on the printed circuit board (10) is generated with the help of additional aids. It is possible here to use spring elements (30) or elastomer strips (31) acting on the power component (14). Furthermore, multi-part support elements (40), or respectively plastic elements (45) can also be employed, which respectively act directly on the printed circuit board (10). A good heat dissipation from the power component (14) via the rim (28) of the housing bottom is possible by means of this.

The apparatus includes a plurality of components, that is, at least one throttle device accommodated rotatably in a throttle valve housing and actuatable by a throttle valve control motor, an electronic control unit, a regenerating valve, and/or an air flow rate meter, which according to the invention are accommodated in a common housing as a premountable structural unit. The apparatus of the invention is intended in particular for mixture-compressing internal combustion engines with externally supplied ignition.

Abstract: The housing (10) of an electrical device, in particular a switching and control device for motor vehicles, includes an upper shell (11) and a lower shell (12), and PC boards (15, 25) are located in both shells (11, 12). The required power components (17) are distributed to both PC boards (15, 25). The lower shell (11) of the housing (10) has side walls (16) encompassing three sides. The upper shell (11) has, in addition to the outer rim (21) extending around three sides, a protrusion (22) protruding into the housing on two opposed sides, so that a space (23) is created between the rim (21) and the extension (22). In the assembled state, the side wall (16) protrudes into the space (23) in the other shell (12). The power components (17) rest on the inner wall of the side wall (16) or of the extensions (22), so that the lost heat can be dissipated in a simple way.

Abstract: In the case of a switching element, a pressure-compensation element (20) is inserted in the base body (10) of the terminal strip (11) in a recess so that a pressure compensation is possible between the interior of the housing (17) and the outer atmosphere. By means of this special arrangement of the pressure-compensation element (20) in the terminal strip (11) it is possible to test the functional capability of the pressure-compensation elements in the installed state in a simple way without additional testing processes.

Abstract: Securing mechanisms are employed in known plug connections, which have components designed in a complicated way, the manufacture and assembly of which entails high cost and which result in bulky plug connectors. The plug connection in accordance with the invention is designed in such a way that a securing ring (18) formed in one piece on a second part (11) has stop shoulders (29) which, for securing the plug connection, grip, stationary detents (46) of a first part (41). The securing ring (18) has the shape of a convexly closed polygon (24), the corner points (26) of which have a reduced wall thickness in comparison with the polygon lines (27). The polygon lines (27) can be kinked at the corner points (26) by means of squeezing pressure forces acting on the securing ring (18), which allows the disconnection of the securing of the plug connection. This results in a plug connection of low mass which can be manufactured in a cost-effective manner.
