| 1. | An electronics accommodation (1) comprising a housing (2) with at least one recess (6) provided therein for leading through a cable, as well as a cover (5) for closing off the accommodation, characterized in that in at least one wall of the housing (2) there is included a printed circuit board with electronics (3). |
| 2. | An electronics accommodation as claimed in claim 1, characterized in that the connectors (4) and/or the cooling bodies for the electronics (3) project outwardly from the accommodation. |
| 3. | An electronics accommodation as claimed in claim 1 or 2, characterized in that the electronics (3) are embedded in the wall of the accommodation during casting of the accommodation. |
| 4. | An electronics accommodation as claimed in any one of claims 1 to 3, characterized in that the accommodation is made of synthetic material. |
| 5. | An electronics accommodation as claimed in any one of claims 1 to 4, characterized in that the electronics (3) are included in the bottom of the accommodation. |
| 6. | An electronics accommodation as claimed in any one of the preceding claims, characterized in that in the recess (6) there is disposed an elastic material (7) in which there is provided at least one aperture (9) for leading through a cable. |
| 7. | An electronics accommodation as claimed in any one of the preceding claims, characterized in that that the cover (5) is provided with an elastic sealing edge (7). |
| 8. | An electronics accommodation as claimed in any one of the preceding claims, characterized in that the edge of the housing (2) by which the cover (5) is supported is provided with an upright rim. |
Such an electronics accommodation is known.
With the known electronics accommodation the printed circuit board with electronics fitted thereon is fastened to the bottom of the accommodation. The known accommodation has the disadvantage that, when it is disposed on a machine which it exposed to vibrations and/or shocks, the electronics will soon be out of order.
The invention aims at obviating the above-mentioned drawback or at least minimizing same.
In accordance with the invention this is achieved in that in at least one wall of the housing there is included a printed circuit board with electronics. Due to the fact that the electronics are included in the wall, it is impossible for the electronics to move relative to the accommodation and to get out of order as a result thereof.
According to an inventive feature, the connectors and/or the cooling bodies of the electronics project outwardly from the accommodation. According to again another inventive feature, the electronics are embedded in the wall of the accommodation by means of casting. According to an inventive feature, the casting means may be constituted by synthetic material. According to a further inventive feature, electronics are included in the bottom of the accommodation.
According to again another inventive feature, in the recess in the accommodation there is disposed an elastic material in which there is provided at least one aperture for leading through the cable. The elastic material ensures the cable to remain well enclosed, so that moisture and dirt are prevented from penetrating into the accommodation. For the purpose of obtaining a still better sealing, the cover is
provided with an elastic sealing edge. Said sealing edge is e. g. made of rubber. According to again another inventive feature, the edge of the housing by which the cover is supported may also be provided with an upright rim. This upright rim may be formed during casting of the accommodation.
The invention will now be explained in further detail with reference to the accompanying figures, in which: Figure 1 is a plan view of the electronics accommodation without cover; Figure 2 is a cross-section of the electronics accommodation according to the arrow II-II in Figure 1; Figure 3 is a side view of the closed-off electronics accommodation, and Figure 4 is a cross-section of the closed-off electronics accommodation according to the arrows IV-IV in Figure 3.
Figure 1 is a plan view of an electronics accommodation 1 comprising a housing 2 with electronics 3 fitted on a printed circuit board disposed therein. As shown in Figure 2, the electronics 3 are embedded in the bottom of the housing 2. During casting of the housing 2, the electronics 3 are embedded in the bottom of the housing 2, the connectors 4 remaining projected outwardly from the housing 2. Non-shown cooling bodies for cooling the electronics 3 also project outwardly from the bottom of the housing 2. The housing 2 is preferably made of synthetic material.
Figure 3 shows a side view of the electronics accommodation 1, in which the housing 2 is closed off by means of a cover 5. In the side wall of the housing 2 there is provided a recess 6 which is filled up with elastic material 7.
The elastic material 7 may be constituted e. g. by rubber. In the elastic material 7 cuts 8 have been made from the upper side, said cuts 8 extending as far as bores 9 which have been made in the elastic material 7. Power cables, which are connected to the
connectors 4, may be brought into the bores 9 via the cuts 8.
Because of the elasticity of the material the cables are well enclosed, so that dirt and water are prevented from penetrating into the housing 2. As shown in Figure 4, the elastic material 7 is retained by the curved edge 10 of the cover 5 and by the upright rims 11 of the accommodation. The cover 5 is provided at its lower side with an elastic sealing edge 12 which is supported by a rebate 13 of the housing 2. The cover 5 may be detached by means of screws 14. The cover 5 is preferably made of metal and the cooling bodies for the electronics 3 may be connected, if desired, to the cover 5, so as to cool the electronics optimally.
