Abstract

The invention relates to a device for receiving and supporting busbars as electrical connection elements for a circuit board. The device is arranged in a gap between the circuit board and a housing wall, in contact with the circuit board and with the housing wall, and comprises a housing which receives at least one busbar and which, on a first end, is designed with a supporting element for holding the device on the housing wall. Here, the housing wall is designed with a screw base of a screw connection, and the supporting element is designed in the form of an eyelet such a manner that the supporting element encloses the screw base at least partially, and the circuit board is connected on a front side of the screw base to the housing wall.

First claim

What is claimed is:

1. A device for receiving and supporting busbars as electrical connecting elements for a circuit board, wherein the device is arranged in a gap between the circuit board and a housing wall, in contact with the circuit board and with the housing wall, the device comprising:
a housing which receives and supports at least one busbar, and on a first end, includes a supporting element for holding the device on the housing wall, wherein the housing wall includes a screw base of a screw connection, wherein the supporting element is an eyelet wherein the supporting element encloses the screw base at least partially so that the screw base is disposed therein, and wherein the circuit board is connected to the housing wall in direct contact with a front side of the screw base and a front side of the supporting element, wherein the supporting element minimizes mechanical stresses transmitted to the circuit board when the at least one busbar is assembled to a pin connection protruding from the housing wall.

2. The device according to claim 1 , wherein an inner side of the supporting element is conical, and an outer side of the screw base is conical, wherein the inner side of the supporting element and the outer side of the screw base correspond to one another and are in flat contact with one another.

3. The device according to claim 1 , wherein the housing is formed from a first housing element and a second housing element.

4. The device according to claim 1 , wherein the at least one busbar further comprises a clamping device on a first end, and the device, on a side facing the housing wall, includes at least one passage opening corresponding to arrangement of the clamping device, and wherein the pin connection protruding from the housing wall is inserted through the passage opening into the clamping device.

5. The device according to claim 4 , wherein the at least one busbar further comprises a plug connection on a second end, and the device, on a side facing the circuit board, includes at least one passage opening corresponding to arrangement of the plug connection, and wherein the plug connection is arranged to protrude from the device through the passage opening corresponding to arrangement of the plug connection in a direction of the circuit board.

6. The device according to claim 1 , wherein the housing of the device is formed from an electrically nonconductive material.

7. The device according to claim 3 , wherein the first housing element and the second housing element include locking elements for clipping or locking to one another.

8. The device according to claim 1 , wherein the supporting element has a slot and is an open eyelet.

9. The device according to claim 1 , wherein the housing further comprises a fastening eyelet which is a through-hole for receiving a pin or a screw and which is formed on a second end of the device which is distal with respect to the first end.

10. The device according to claim 1 , wherein the housing includes passage openings for implementation and preliminary fixation of electrical connections of electronic components arranged on the housing wall for connection to the circuit board.

11. The device according to claim 1 , wherein the housing has formations as spacers, so the device is in contact with the housing wall by means of the formations.

12. The device according to claim 1 , wherein the housing has formations as spacers, so that the device is in contact with the circuit board by means of the formations and the supporting element.

13. A use of the device according to claim 1 on an electrically driven compressor of a refrigerant circuit of an air conditioning system for conditioning air of a passenger space of a motor vehicle.

14. A device for receiving and supporting busbars as electrical connecting elements for a circuit board, wherein the device is arranged in a gap between the circuit board and a housing wall, in contact with the circuit board and with the housing wall, the device comprising:
a housing which receives and supports at least one busbar, and on a first end, includes a supporting element for holding the device on the housing wall, wherein the housing wall includes a screw base of a screw connection, wherein the supporting element is an eyelet wherein the supporting element encloses the screw base at least partially, and wherein the circuit board is connected on a front side of the screw base to the housing wall, wherein the supporting element is designed in terms of dimensions in such a manner that it slides over the screw base in an assembly direction in which the circuit board is moved towards the housing wall wherein the screw base is a conical or a frustoconical shape, a diameter of the screw base and a diameter of the supporting element are configured so that they taper in a direction opposite the assembly direction.

15. The device according to claim 14 , wherein the supporting element minimizes mechanical stresses transmitted to the circuit board when the at least one busbar is assembled to a pin connection protruding from the housing wall.
