Abstract: A method is provided for producing a tight, form-fitting connection between a housing cover and a housing body, wherein the housing cover has cover tabs protruding from an edge thereof, and an edge area of the housing body has recesses for respectively receiving the cover tabs. The method involves positioning the housing cover on the housing body and deforming the cover tabs in the housing recesses to produce the tight, form-fitting connection in a single operation with a single tool.

Abstract: For a motor vehicle control device, a housing lid and a base plate form a hollow area that contains an interconnect device arranged on the inner side of the housing lid. The housing lid has at least one opening surrounding the interconnect device, adjacent to an electronic component and/or an electrical contact area on the interconnect device. On or in the opening, a flexible foil conductor strip is arranged with an end section thereof covering the opening. A lid plate covers the opening completely, and the interposed foil conductor strip is thus connected in an oil-tight manner with the housing lid. Electrical connection lines between the components and/or the contact areas on the interconnect device and an electrical contact area on the end section of the foil conductor strip create the electrical connection between the control electronics on the interconnect device and the surrounding area outside of the control device.

Abstract: A motor vehicle control device includes a housing lid and a base plate that are connected with each other in an oil-tight manner via a frame. An interconnect device with at least one electronic component and/or at least one electrical contact area is arranged on the base plate. Respectively in the area of an electronic component and/or an electrical contact area, the base plate includes a foil conductor strip, of which an end section facing the interconnect device in turn includes an electrical contact area. The frame completely surrounds the interconnect device and includes one opening respectively in the area of an electrical contact area of the foil strip. Via connection lines, the electronics on the interconnect device are electrically connected with the contact area in the opening, and thus with the electronic components outside the control device.

Abstract: The invention relates to a method for producing a tight, form-fitting connection between a housing cover (1) and a housing body (2), cover plates (3) being formed on the edge of the housing cover (1), and regions (7, 8) being arranged on the edge of the housing body (2), for receiving the cover plates (3), enabling the positioning of the housing cover (1) on the housing body (2) and the production of the tight, form-fitting connection in a single operation with a single tool (5, 6). Once the housing cover (1) has been positioned on the housing body (2), the cover plates (3) are shaped in such a way as to produce the tight, form-fitting connection in the regions (7, 8) of the housing body (2).

Abstract: A motor vehicle control device comprises a housing lid (12) and a base plate (1), which are connected with each other in an oil-tight manner via a frame (3). On the base plate (1), an interconnect device (4) is arranged with at least one electronic component (5) and/or at least one electrical contact area (6). The base plate (1) comprises respectively in the area of an electronic component (5) and/or an electrical contact area (6) a foil conductor strip (7), the end section (10) of which, which faces the interconnect device (4), in turn comprises an electrical contact area (11). The frame (3) which completely surrounds the interconnect device (4) comprises one opening (9) respectively in the area of an electrical contact area (11) of the foil strip (7). Via connection lines (8), the electronics on the interconnect device (4) are electrically connected with the contact area (11) in the opening (9), and thus with the electronic components outside the control device.

Abstract: For a motor vehicle control device, a housing lid (1) and a base plate (2) form a hollow area (3) for holding an interconnect device (4), which is arranged on the inner side of the housing lid (1). The housing lid (1) comprises at least one opening (9) in the area completely surrounding the interconnect device (4), adjacent to an electronic component (5) and/or an electrical contact area (6) on the interconnect device (4). On or in the opening (9) one flexible foil conductor strip (7) respectively is arranged in such a manner that an end section (10) of the foil conductor strip (7) completely covers the opening (9). A lid plate (12) covers the opening (9) completely, and the foil conductor strip (7) which lies between is thus connected in an oil-tight manner with the housing lid (2).
