Abstract

The invention relates to a fastening device comprising a profile strut (1) and a plug-in nut (3) mounted in a hole (2) of the profile strut (1), wherein the plug-in nut (3) has a threaded nut ( 5), the threaded nut is retained on the buckle (4), characterized in that the buckle (4) has a first and a second actuation end (6, 7), the plug-in nut (3) from the hole (2) protrudes beyond the actuating end, wherein, in the locked position of the actuating ends (6, 7) relative to each other, the edge (2.1) of the hole (2) is received in the receptacle (8) of the clasp (4) . The invention also relates to a corresponding switch cabinet housing.

Description

Technical field [0001] The present invention relates to a fastening device comprising a profile strut and an insert nut mounted in a hole of the profile strut, which has a threaded nut that holds on a buckle. This fastening device is known from DE 199 37 892 C1. Similar fastening devices are also described in DE 198 60 434 A1. Background technique [0002] The disadvantage of the prior art fastening device is that when the bolt is screwed into the threaded nut of the inserted nut, it may occur, and the inserted nut is reversed in the hole of the profile strut, and the bolt cannot be screwed. In the inserted nut, or bolt barriers are in the threaded nut of the plug nut. Inventive content [0003] Accordingly, it is an object of the present invention to further improve the fastening device of the above type such that it is firmly placed in the well of the profile strut, and prevents the insertion nut from being unexpected in the well. [0004] Accordingly, the fastening device of ...
