Abstract

A seal arrangement for a plug-in connector for establishing electrical connections via a housing, in particular a device for driving a compressor. The seal arrangement exhibits a mounting element to accommodate plug-in connectors for transmitting electrical energy and data, and a sealing element located between the housing and the mounting element. The mounting element is designed with a flange with a sealing surface facing in the direction of the housing. The sealing surface of the flange thus exhibits a first contour and the housing exhibits a second contour in the area of the location of the sealing surface surrounding a pass-through opening.

First claim

The invention claimed is:

1. A seal arrangement of a plug-in connection for establishing electrical connections through a housing, in particular of a device for driving a compressor, the seal arrangement comprising:
a mounting element for accepting plug-in connectors to transfer electrical energy; and
a sealing element arranged between the housing and the mounting element, wherein the mounting element is produced with a flange with a sealing surface that points in a direction of the housing, wherein the sealing surface of the flange includes a first contour and the housing includes a second contour around a pass-through opening in an area of the sealing surface, each in the form of at least one recess and formation that wrap around an entire perimeter of the pass-through opening, wherein the contours are produced and arranged in such a way that they correspond to one another and that the sealing element is produced as a single-piece component which wraps fully around the mounting element in a radial direction with a first section that acts in the radial direction, as well as with a second section that acts in the radial direction, wherein the sealing element is arranged with the second section between the sealing surface of the flange with the first contour and the housing with the second contour.

2. The seal arrangement according to claim 1 , wherein the flange projects from the mounting element in the radial direction and covers an entire circumference of the mounting element, wherein the sealing surface of the flange is arranged and aligned on a plane fixed in the radial direction such that it points in an axial direction to the housing.

3. The seal arrangement according to claim 2 , wherein the recess of the first contour or the second contour is a slot with a depth that is aligned in the axial direction.

4. The seal arrangement according to claim 3 , wherein the formation of the first contour or the second contour is a section that is raised from a respective surface and whose height is aligned in the axial direction.

5. The seal arrangement according to claim 4 , wherein the recess and the formation of the first contour or the second contour are arranged such that they run parallel to one another.

6. The seal arrangement according claim 2 , wherein the sealing element is produced with an opening that runs in the axial direction for accepting the mounting element.

7. The seal arrangement according to claim 6 , wherein the first section of the sealing element includes a hollow cylinder-shaped wall that is aligned in the axial direction with a first end face and a second end face.

8. The seal arrangement according to claim 7 , wherein the second section of the sealing element is arranged and aligned on a fixed plane that is aligned in the radial direction, wherein the sealing element is arranged such that its second section is in contact with a first axial sealing surface on the sealing surface of the flange and with a second axial sealing surface on the housing when the plug-in connection is established.

9. The seal arrangement according to claim 8 , wherein the first section of the sealing element on the second end face, produced distally to the first end face, is connected to the second section of the sealing element around a full circumference of an opening for accepting the mounting element.

10. The seal arrangement according to claim 1 , wherein the plug-in connectors are each produced in the form of a straight pin.

11. The seal arrangement according to claim 1 , wherein the mounting element is produced such that it can be fixed to the housing.

12. The seal arrangement according to claim 11 , wherein the flange of the mounting element includes pass-through openings for attaching fixings, wherein each of the fixings is arranged such that it is guided through one of the pass-through openings.

13. The seal arrangement according to claim 1 , wherein an interlock connection is produced as an electrical locking mechanism that is connected in an electrically conductive way to the plug-in connectors of the plug-in connection.

14. A device for driving the compressor of a vaporous fluid, in particular an electric motor, including the housing, as well as a stator and a rotor that are arranged along a common longitudinal axis, wherein a connection arrangement to transfer electrical energy and data is produced with the seal arrangement of the plug-in connection for establishing electrical plug-in connections through the housing according to claim 1 .

15. The device according to claim 14 , wherein the connection arrangement is produced on a first end face of the stator that is aligned in an axial direction.

16. Use of a device to drive the compressor, in particular the electric motor, for compressing the vaporous fluid, according to claim 14 for the compressor of a refrigerant in a refrigerant circuit of a motor vehicle air conditioning system.
