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

Control device consisting of at least two housing sections

In order to improve an arrangement for mounting a wiring harness on a support plate with a laminated-on substrate for electrical and/or electronic components such that the latter has high reliability while being simpler and thus more economical to manufacture, the connecting wires of the wiring harness are connected in electrically conductive fashion directly to electrical connection elements of the substrate. In the vicinity of this connection, the wiring harness is at least partly embedded into a sealing medium enclosing the connection.

Arrangement for mounting a wiring harness on a support plate

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.
