Abstract

The invention relates to a fastening arrangement including a profiled strut and a plug-in nut mounted in an aperture of the profile strut, wherein the plug-in nut has a threaded nut held on a clasp, wherein the clasp has a first and a second actuating end, via which the plug-in nut projects out of the aperture, wherein in a locking position of the actuating ends relative to each other an edge of the aperture is received in a receptacle of the clasp. Additionally, a corresponding switch cabinet housing is disclosed.

First claim

The invention claimed is:

1. A fastening arrangement comprising:
a profile strut; and
a plug-in nut mounted in an aperture of the profile strut;
wherein the plug-in nut has a threaded nut held on a clasp;
wherein the clasp includes a connection section connecting an upper part and a lower part together in a spaced-apart relationship, a first actuating end forms a first free end of the upper part and a second actuating end forms a second free end of the lower part, the plug-in nut projects out of the aperture by way of the first free end and the second free end;
wherein the clasp further includes at least one of a first projecting contact claw extending from the connection section, and a second projecting contact claw extending from the lower part between the second actuating end and the connection section;
wherein in a locking position of the first actuating end and the second actuating end relative to each other an edge of the aperture is received in a receptacle of the clasp; and
wherein the first actuating end and the second actuating end are overlappingly arranged in front of a profile side of the profile strut having the aperture, the first actuating end defines a first tool opening enclosed by the first actuating end, the second actuating end defines a second tool opening enclosed by the second actuating end, and the first tool opening is aligned with the second tool opening.

2. The fastening arrangement according to claim 1 , in which the receptacle is substantially U-shaped and formed on the first or the second actuating end.

3. The fastening arrangement according to claim 1 , in which the receptacle is arranged between the first or the second actuating end and the threaded nut.

4. The fastening arrangement according to claim 1 , in which the clasp is a shaped sheet metal part and the receptacle is a U-shaped sheet metal folded edge.

5. The fastening arrangement according to claim 1 , in which the receptacle has boundary walls spaced apart from each other, of which a first boundary wall, in the locking position, is arranged in front of an inner side of the edge of the aperture, and of which a second boundary wall, in the locking position, is arranged in front of an outer side of the edge of the aperture, opposite the inner side.

6. The fastening arrangement according to claim 1 , in which at least one of the actuating ends in a portion, with which the actuating end passes through the aperture, has a dimension in the longitudinal direction of the edge accommodated in the receptacle, which dimension corresponds to a length of the edge in the longitudinal direction.

7. The fastening arrangement according to claim 1 , in which, in a release position of the actuating ends relative to each other in which the actuating ends are displaced relative to each other compared to the locking position, the edge of the aperture is out of engagement with the receptacle of the clasp.

8. The fastening arrangement according to claim 1 , in which the actuating ends each have a handle which protrude at a distance from each other through the aperture via an outer side of the profile strut and which can be transferred from the locking position into a release position against mechanical preloading of the clasp.

9. The fastening arrangement according to claim 1 , wherein the first tool opening and the second tool opening form a tool insertion opening which is delimited by a first boundary edge of the first tool opening and oppositely by a second boundary edge of the second tool opening.

10. The fastening arrangement according to claim 9 , in which at least one of the first tool opening and the second tool opening has a toothing at a third boundary edge extending in the direction of an adjustment direction between the locking position and the release position of the actuating ends.

11. The fastening arrangement according to claim 10 , in which a fourth boundary edge opposite the third boundary edge is arranged at a distance from the third boundary edge and forms a counter bearing for a toothed drive, in particular for a screwdriver with a multi-circular drive.

12. The fastening arrangement according to claim 10 , in which another one of the at least one of the first tool opening and the second tool opening is formed circularly and has an inner diameter which corresponds to an outer diameter of a toothed drive.

13. A switch cabinet housing comprising: the fastening arrangement according to claim 1 ; wherein the profile strut is either a profile strut of a frame of the switch cabinet housing or an interior component for an interior installation of the switch cabinet housing, in particular a mounting chassis.
