To achieve an excellent seal for the housing in a transitional region among the base, the cover, and an intermediate wall of the plug body, a groove is formed in the cover, in which a sealing compound is placed. During assembly of the components, the sealing compound is displaced from the intermediate wall in a region of an additional sealing compound applied to the base, the two sealing compounds meeting in an overlap region.

Abstract: In an arrangement composed of a substrate and a heat sink, the substrate is provided on a first side with at least one power component arranged on a first large-surface printed circuit trace and, on a second side opposite the power component, with a second large-surface printed circuit trace, which is connected in a thermally conductive manner to the first printed circuit trace via via holes. The substrate is mounted at the second side onto the heat sink in a thermally conductive manner, in order to achieve a good heat coupling of the substrate to the heat sink and the same time to avoid an undesirable electrical contact between the potential-carrying printed circuit traces and the heat sink. The substrate having spacer elements arranged on the second side is placed onto the heat sink and to hold it at a defined distance from the heat sink, the gap formed by the distance between the substrate and the heat sink being filled with a thermally conductive filler.

Abstract: A connector arrangement of a control system with a controller in a motor vehicle is designed so that it can be manufactured advantageously and is reliable in operation.To do so, the connector arrangement and the respective controller are designed so that several separate connector sockets with externally accessible contact elements are arranged on the controller, which is mounted on the vehicle's internal combustion engine as a surface-mounted controller, some of the contact elements being designed as high-current contact elements which are connected directly to one another through busbars running inside the controller.The respective mating connectors can be connected to the connector sockets, the mating connectors being electrically connected to components of the vehicle over cable harnesses or cable segments, where a first mating connector connected to cable segments is composed of partial mating connectors which can be handled independently of one another.

Abstract: A method is disclosed for applying phosphate coatings to surfaces of zinc, iron, aluminum, and the alloys thereof by wetting with a phosphatizing solution containing divalent cations and phosphate to form a liquid film, and subsequently drying on the liquid film wherein the metal surfaces are wetted with a phosphatizing solution, which is free from elements of sub-groups 5 and 6 of the Periodic Table, said phosphatizing solution containing:0.5 to 8 g/l nickel;2 to 20 g/l manganese;18 to 170 g/l of phosphate (calculated as P.sub.2 O.sub.5);and has an acid number of 0.4 to 0.8, such that after drying on, a phosphate layer having a weight per unit area of 0.3 to 3.0 g/m.sup.2, is obtained, where in the case of phosphatizing surfaces of iron, aluminum or the alloys thereof, the phosphatizing solution necessarily contains 0.5 to 5 g/l of zinc, and in the case of phosphatizing surfaces of zinc or zinc alloys the phosphatizing solution either contains zinc or is free from zinc.

Abstract: Electronic engine management systems have a plurality of individual components, some of which are relatively far away from one another. Electrically connecting the individual components, particularly to an electronic control unit therefore requires relatively long electrical connecting lines and relatively many plug connection. 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: 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: The housing for an electronic circuit provided with a connection plug, particularly for control device electronics of an internal combustion engine of a vehicle, includes a cooling frame to which a printed circuit board having the electronic circuit is fastened and which has at least one cooling portion with which power components connected to the printed circuit board are connected so as to conduct heat, and also includes a cover enclosing the printed circuit board. For a simple construction, it is suggested that the cooling frame (5) be constructed as a flat frame (6) with flat frame legs (8, 8a, 8b, 8c, 8d) substantially parallel to the plane (7) of the printed circuit board (3), the housing cover pieces (12, 13) forming the cover (11) being arranged at the upper and lower sides (9, 10) of the flat frame (6).

Abstract: 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.

Abstract: Two photoelements with inputs for different wave lengths of radiation from a common source are serially connected individually to the inputs of high gain inverting amplifiers with feedback to adjust the voltage across the photoelement to zero, so that the outputs of the amplifiers are proportional to the short circuit currents through the photoelements. An algebraic calculating circuit forms the ratio of the outputs of the amplifier and provides for indication and/or control. The effectiveness of this ratio output is controlled in dependence upon proper orientation to the radiation emitting source.
