A plug-in module for adjusting motors of electric-motor operated window openers in a motor vehicle has at least one plug insertable in a transmission housing of a window lifter. A plug housing is composed of a plastic material with partially injection molded contact elements and motor contacts. The motor contacts have freely located connection portions which have an end-side contact portion for contacting with an associated countercontact and also a spring portion which supports the contact portion and allows a position orientation of the contact portion to the countercontact.

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.

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.

Apparatus for an internal combustion engine

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.

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. This plug connection is preferably employed in motor vehicles which are subject to oscillation increases during operation.

Housing for an electronic circuit

A spring element, for securing components of an electronic control device, is essentially U-shaped, with a bridge portion (16), which rests on an end (11A) of a cooling fin (11) mounted perpendicularly on a printed circuit board (13), and a pair of depending spring legs (17, 18), one of which presses against a side face (11C) of the cooling fin (11) and the other of which presses a power component (14) against a major surface (11B) of the cooling fin (11). Preferably, the spring element (15, 15A) is formed with a pair of slots (23, 24) which facilitate engagement by a pair of tongs (25, 26) of an automatic mounting device. The tongs can spread open the spring element and position it around the cooling fin (11) and power component (14) without exerting any harmful shear forces on the fin or component. Preferably, each spring leg has a convex central section, below the slot, and a concave bottom or terminal end. Optionally, the inner surface of the terminal end (21A, 22A) is formed with a claw or tooth (27, 28) for better holding.

The flexible printed circuit device, includes at least one hybrid circuit structure having assigned contact areas, a rigid printed circuit board, a flexible printed circuit board portion also having assigned contact areas on one end region thereof and being connected electrically to the rigid printed circuit board, a plurality of bonding electrical conductors, each of the electrical conductors being bonded at one end thereof to one of the assigned contact areas on the at least one hybrid circuit structure and, at the other end thereof, to one of the assigned contact areas on the end region of the flexible printed circuit board portion; and a rigid support, the hybrid circuit structure being mounted on the rigid support. The end region of the flexible printed circuit board portion is fixedly mounted on the rigid support in side-by-side relationship with the hybrid circuit structure. A protective frame is provided enclosing the electrical conductors electrically connecting the assigned contact areas on the hybrid circuit structure and the end region of the flexible printed circuit board portion.

Housing for receiving electric control devices, in particular for motor

To permit external adjustment of a potentiometer (3) having an adjustment head (4), and located within a sealed housing (1), while permitting placement of an adjustment insert (7) from the outside of the housing through a bore (6) thereof, and compensate for manufacturing and positioning tolerances, the insert element is a unitary structure of a tough plastic, such as polyamide (nylon), sealingly inserted through the opening and retained in the opening by snap-over hooks (13) engaging over the inner wall (25) of the housing, and retaining a screw head (8) of the insert element therein. Longitudinal and transverse deviation from alignment of the axis of the opening (6) and the rotation axis of the adjustment element (4) of the potentiometer is obtained by resiliently deflectable cross-joints (14, 14'; 17, 18) formed in an intermediate portion of the insert element, which cross-joints are connected by a S-shaped resiliently deflectable connecting portion. The end (19) of the insert element, fitting against the adjustment portion (4) of the potentiometer, and/or a screwdriver blade-like engagement blade (24) are preferably formed with self-aligning engagement surfaces (20) to permit self-seeking positioning of engagement of the insert with the potentiometer in spite of possible initial, or later misalignment due to tolerances.

Electronic control unit structure

To increase the heat capacity of a heat sink and heat dissipating structure combined with an electrical component, typically a transistor, for example of the TO 220 or SOT 93 type, a heat transferring base plate (3), with the interposition of an insulating, heat conducting foil (6), engages one flat surface of the element (11), and a second heat transferring element (17) is provided, pressed by a spring (24) against the other major surface, or a portion of the component (11). A plastic holder (7) is provided, attached to the base plate (3) for example by snap-in hooks (8), formed with openings to receive the component, and position the component against the base plate while, also, being formed with abutments to position the second heat transferring element which, for example, is block or plate-like. The spring, preferably, is a leaf spring having projecting arms extending, from both sides of a central portion (25), over two adjacently located components (11) and the second heat transferring elements (17) respectively, and engaging the holder (7) to form a subassembly therewith, the subassembly then being riveted, by rivets extending through the spring (24) to the base plate.
