Abstract

A plug-in connection arrangement for a component includes a first portion having a first groove contour in a first annular groove arranged in the first portion, and a second portion having a second groove contour in a second annular groove arranged in the second portion. Via a resilient connection arrangement element arranged between the first portion and the second portion in the second annular groove, the first portion and the second portion can have a retention position relative to each other in a first position and which can be moved in an axial direction into a second position which is provided for operation. The second position is a sealing engagement position.

First claim

The invention claimed is:

1. A plug-in connection arrangement for a component, the plug-in connection arrangement comprising:
a first portion having a first groove contour in a first annular groove arranged in the first portion;
a second portion having a second groove contour in a second annular groove arranged in the second portion;
the first portion having at a first edge a projection, the projection having an inclined introduction member and a hook-like burr;
the first annular groove being constructed in such a manner that the first annular groove is separated from the projection by the hook-like burr;
the first portion, on the first annular groove, having the first groove contour having a chamfered first groove base and the second portion, on the second annular groove, having the second groove contour having a chamfered second groove base; and
wherein, via a resilient connection arrangement element arranged between the first portion and the second portion in the second annular groove, the first portion and the second portion can have a retention position relative to each other in a first position by a resilient deformation of the resilient connection arrangement element, and which can be moved in an axial direction into a second position which is provided for operation, and
wherein in the first position the first portion is subjected to at least one retention force as a result of the resilient deformation of the resilient connection arrangement element between the inclined introduction member and the hook-like burr, and the chamfered second groove base of the second portion, and
wherein the second position is a sealing engagement position.

2. The plug-in connection arrangement as claimed in claim 1 , wherein the resilient connection arrangement element is constructed in the form of a sealing and retention element and/or as an O-ring.

3. The plug-in connection arrangement as claimed in claim 1 , wherein the first portion and the second portion are each constructed in a cylindrical manner and/or have a cylindrical edge.

4. The plug-in connection arrangement as claimed in claim 1 , comprising:
a volume of the resilient connection arrangement element which is deformed in the first position;
a volume of the resilient connection arrangement element which is deformed in the second position;
a groove volume of a recess which is formed by the second annular groove and which is delimited by the second groove contour; and
wherein the volume of the resilient connection arrangement element which is deformed in the first position projects more substantially beyond the groove volume of the recess than the volume of the resilient connection arrangement element which is deformed in the second position, such that a cross-section of the resilient connection arrangement element in the second position is more elliptical than in the first position.

5. The plug-in connection arrangement as claimed in claim 1 , wherein the resilient connection arrangement element has a cross-sectional region,
the cross-sectional region being produced in the first position by the resilient deformation in a radial direction that is transverse relative to the axial direction,
a smaller extent of the cross-sectional region being limited by the inclined introduction member of the projection, and
a larger extent of the cross-sectional region projecting into the first annular groove behind the hook-like burr.

6. The plug-in connection arrangement as claimed in claim 1 , wherein in the first portion the chamfered first groove base extends in a sloping manner toward the projection and the second portion has an abutment which limits an axial movement of the first portion relative to the second portion of the plug-in connection arrangement in an axial direction.

7. The plug-in connection arrangement as claimed in claim 6 , wherein the first portion in the second position is subjected to at least one retention force in a radial direction as a result of a resilient deformation of the resilient connection arrangement element between the chamfered first groove base and the chamfered second groove base, wherein an annular groove cross-section of a total groove which is formed from the first and second annular grooves tapers from the projection, wherein the groove bases taper toward each other from the projection, and wherein the projection and the abutment are in contact with each other.

8. The plug-in connection arrangement as claimed in claim 1 , wherein the projection has an axial length such that in the second position the first portion is subjected, as a result of a resilient deformation of the resilient connection arrangement element between the chamfered first and the chamfered second groove bases and the hook-like burr, to at least one retention force in a radial direction and a positional force in an axial direction, wherein a retention pressure in particular presses the first and second portions against each other and/or a positional pressure presses the projection and the abutment against each other.

9. The plug-in connection arrangement as claimed in claim 1 , wherein, in a third position is provided before factory-side assembly, the first and second portions have a preliminary retention position relative to each other in which the first portion is subjected in particular to a retention force as a result of a resilient deformation of the resilient connection arrangement element between the first inclined introduction member and the chamfered second groove base, in particular the deformation is free from an action of the hook-like burr.

10. The plug-in connection arrangement as claimed in claim 1 , wherein the first portion is a portion of a cover which closes the second portion in an air-tight manner in the sealing engagement position which is present as a result of the second position.

11. The plug-in connection arrangement as claimed in claim 1 , wherein the component may be used to transport a gas in a sealing engagement position which is present as a result of the second position.

12. A component having a motor housing and a crankcase of a compressor, the component having a plug-in connection arrangement as claimed in claim 1 , wherein the first portion is constructed as a motor cover and/or a shaft, and wherein the second portion is constructed as a motor housing.

13. A method for preparing, at a factory side, a plug-in connection arrangement as claimed in claim 1 , the method comprising:
positive-locking positioning of a receiving member of a first portion on the carrier of a second portion in a first position of a retention position, which receiving member is constructed so as to have a first annular groove, or positive-locking positioning of a carrier of the second portion in a receiving member of the first portion in the first position of a retention position, which carrier is constructed so as to have a second annular groove,
axially moving the first portion and the second portion relative to each other in an axial direction in order to move the plug-in connection arrangement into the second position of a sealing engagement position, and
arranging a sealing and retention element in the form of an O-ring, in only the second annular groove of a total groove in a third position of a preliminary retention position.

14. A plug-in connection arrangement for a component, the plug-in connection arrangement comprising:
a first portion having a first groove contour in a first annular groove arranged in the first portion;
the first portion having a projection and a chamfered first groove base which extends in a sloping manner toward the projection
a second portion
