Description

"Enclosure for electronic devices, comprising a device which ensures

  The invention relates to a housing for electronic devices, characterized in that at least one wall of the housing is constructed in the form of

platinum of metal cores.

  Housings for electronic devices

  are known. They have the disadvantage of not being

  designed for high thermal and mechanical stresses

  especially for high-powered

filling density.

  According to DE-OS 3 621 930,

  knows, also, hybrid devices, with

  integrated cuation of heat, which have a metal housing used to evacuate the heat. These devices are very heavy. In addition, the construction of plates

  conductive or hybrid substrates of high

  in the case and their electrical connection are complicated. Advantages of the invention The case according to the invention has, on the other hand,

  advantage in the case of a high density of

  of the enclosed electronic device, that it resists

  te at high operating temperatures and at high mechanical stresses, such as occur for example during the direct operation of the housing in an internal combustion engine of a motor vehicle. The connecting plates of the

  metal cores serving as housing walls

  not only provide the electrical connection of ele- ments of the enclosed electronic apparatus, but they also have a high mechanical stability, and at the same time discharge the heat produced by

  service. As a result, the plate construction con-

  conductors or hybrid assembly groups in the

  case and their electrical connection are very

  ples. In addition, the housing is very light, which simplifies

  essentially folds its fixation, for example

in motor vehicles.

  In a preferred embodiment, the spacers connecting the connecting plates of the metal cores are made of metal and provided with a cooling device, for example with channels for a cooling means. It is advantageous to have for the electronic device

  contained protection against electronic incidents

  magnetic, and an optimal evacuation of heat.

  Other advantages and developments are characterized in that: - the base and the cover of the housing are made in the form of plates of metal cores, which are connected together via

spacers.

  - connecting elements and / or groups

  Assembly weights are chosen as spacers. the assembly groups are made in the form of hybrid assembly groups and / or

  form of conductive plate module.

  - the metal elements have a dis-

  positive cooling, and are thermally coupled

  with the metal connecting plates.

  the assembly groups are provided with contacts on one or both their sides adjacent to the connecting plates of the metal cores.

  the connecting plates of the metal cores

  They have at least one side of a connection plug. - The connection plug is made in the form of an integrated plug of the plates of metal cores. It is particularly advantageous that

  binding plates of the metal cores

  form directly into an integrated electrical plug, so that the electrical connections of the device

  must be very easy to install.

  Two embodiments of the invention are shown in the drawings, and will be explained in

  detail in the following description.

  The drawings show: FIG. 1: a first exemplary embodiment of a housing with two metal core connection plates, and FIG. 2: a second embodiment of a housing with spacing elements.

  made in the form of coolers.

  In the embodiment shown in Figure 1, the cover 1 and the base 2 of the housing 3 are made in the form of connection plates of the metal cores. On the sides, the case is

  delimited by two spacer elements 4 and 5,

  staged in this case made of metal. Between the cover and the base of the housing and perpendicular thereto, several hybrid assembling units 6 are arranged parallel to each other, the connecting elements of which are electrically connected by through-plug contacts 7 and 8 to the cover and at the base of the case 3. It is also possible to

  have the connecting elements on the inside

  lid 1 or base 2, so that the

  enclosure walls are part of the electrical

tronics.

  On the right side of Figure 1, the cover

  1 is made in the form of a flat plug 9, with which the electrical assembly elements can be electrically connected with other connection elements. Base 2 can also be

  made in the form of a flat plug 10.

  In the embodiment shown, the base and the housing cover are not made in a rectangular shape. They have on a longitudinal side an indentation 11 in the form of a circular arc, the diameter of which is adapted to a group which

depends on this case.

  On the rear side of the housing, not visible in the figure, is provided a suitable closure. The connection between the lid 1, the base 2 and the spacers 4 and 5 can be made of a

any appropriate way.

  In the embodiment shown in FIG. 2, the same parts are designated by the

  same reference numbers. A separate description of

these pieces will not be made.

  The housing 3 again has a lid 1 and a base 2, which are made in the form of

  binding plates of metal cores. The delimitation

  Lateral formation is formed by spacers

  and 50 as coolers. Perpendicular-

  at the base and the cover are arranged groups

  6 hybrid hydride assembly, substantially parallel to each other, and which have on their two

  longitudinal sides of contacts 7 and 8, which are

  dice in appropriate holes in the lid and

  the base of the housing 3 and serve for the electrical connection

  tractors. The chillers and 50 have channels 41 and 51 for a cooling means. The heat generated during operation, and which is transmitted from the assembly elements inside the housing, is thus properly discharged. For this, as in the example according to FIG. 1, a good conductive connection of the heat must be ensured between the connecting plates of the metal cores and the

  spacers 40, 50, or 4 and 5.

  The exemplary embodiment shown in

  Figure 2 is made in a substantially

  gular. The front and rear sides are locked by appropriate elements, so that the connecting elements are protected. On the right side of FIG. 2, inserted into the connecting plates of the metal cores, contact plugs 12 are shown, by which the hybrid assembly groups can be connected with other

  connecting elements or control devices.

  It is simply obvious that, thanks to the connecting plates of the metal cores and spacers preferably made of metal on the sides of the housing, optimum mechanical strength is achieved. In addition, good heat dissipation is ensured. Finally, it can be seen that the enclosed electronic assembly parts are

  very well protected against electromagnetic

ticks.
