摘要:
A housing for electronic control devices in motor vehicles comprises a generally parallelepipedal frame of plastics and a metallic envelope with spaced parallel top and bottom walls interconnected by parallel side walls and at least one open face. The top, bottom and side walls define a space and the frame is fitted into such space. The control device includes a printed circuit board and electronic components connected to the printed circuit board and engaged in shaped holding structures of the frame. The printed circuit board is located between the bottom wall and the frame. The printed circuit board is rigidly connected to the metallic envelope by metallic fasteners extending from the top wall through the frame and to the printed circuit board.

A housing for a control device in vehicles is provided. The housing satisfies the requirements of acceleration transmission and reliable ground connection with a simple and inexpensive construction. The housing comprises a metallic shell that has parallel top and bottom walls, opposed side walls interconnecting the top and bottom walls and an open front face. A shaped carrier structure has a pair of opposed lateral edges. Both side walls of the shell have an internal groove extending parallel to and spaced from the bottom wall of the shell. The carrier structure is accommodated within the shell and has its lateral edges fitted in the grooves of the side walls.

A housing for an electronic control device in vehicles comprises a bottom part (10) which has a metallic baseplate (12), and a cover part (14) made of plastic. The bottom part (10) has a front wall (16) made of plastic that rises up from the baseplate and to which a plug collar (18) is integrally molded. The plug collar (18) defines an accommodation for a contact pin carrier (28) formed as a flat strip with through holes for passing contact pins (32). The contact pin carrier (28) can be inserted into the plug collar (18) from inside of the housing.

A housing for use in a vehicle to accommodate a printed circuit board (20, 22) carrying electronic components is provided. The housing has a generally parallelepipedal hood (10) made of plastics and having a plug collar (14) on one of its narrow side walls (12). A base plate closes off the hood (10). The printed circuit board (20) is mechanically and electrically conductively connected on three of the four corners of the hood (10) to a metallic mounting bushing (26). At each of these corners, the hood (10) has a mounting flange (16) and the mounting bushings (26) are anchored in the mounting flanges (16) of the hood (10).

A housing system for safety-relevant control devices in vehicles comprises a receptacle (14) for attachment to a car body and a housing part (12) that can be inserted into the receptacle (14). The receptacle (14) and the housing part (12) have complementary form-fitting elements (28, 30) that represent a coding and that engage each other when the housing part (12) is mounted in the receptacle (14), permitting complete assembly of the housing part (12) into the receptacle (14) only when the form-fitting elements (28, 30), of the receptacle (14) and the housing part (12) satisfy a predefined complementarily condition.

A pressure sensor unit 1 is provided, specifically for automotive engineering applications. A pressure measuring cell 5 is disposed within a main body housing 3, the main body housing having a recess 17 holding a pressure sensor 21 and a pressure transmission medium 27. A separation membrane 31 is disposed between the pressure transmission medium and a supply opening 15 formed in the housing 3, the separation membrane separating the sensed pressure medium from the pressure transmission medium and also closing off and admission opening 29 in the measuring cell housing. The separation medium is held in place between an exterior surface of the measuring cell housing and an interior cooperating surface of the main body housing whereby a sealing closure of the admission opening is established by means of a relative clamping force between the respective cooperating exterior surface of the measuring cell housing and the interior surface of the main body housing when the measuring cell housing and the main body housing are brought into a respective connected position.

The invention relates to a pressure switching device of the type used in motor vehicles and includes a pressure sensor 21 arranged in a housing 3, which generates an electrical signal U according to the pressure p of a pressure medium or monitored fluid transmitted through a supply opening 15 of housing 3. The pressure switching devices includes an interpretation and switching unit 55 adapted to received the electrical sensor signal U and is further adapted to compare the sensor signal with at least one switching threshold value to trigger a switching function or a sequence of switching functions upon the electrical sensor signal exceeding and/or falling short of the switching threshold value.

A pressure sensor comprises a sensor diaphragm which on one of its surfaces can be acted upon by the fluid pressure to be defected. The sensor diaphragm is rigidly supported at its opposite surface. It is made of an elastomeric material of an electrically non-conducting material wherein fine particles of electrically conducting material are homogenously embedded and distributed in such a density that a compression of the sensor diaphragm caused by the fluid pressure results in a measurable change in its electrical resistivity.
