DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

[0031] In the figures of the drawings, identical reference designations denote identical or functionally identical elements, assemblies, components or method steps, unless stated otherwise.

[0032] FIG. 1 is a schematic illustration of a housing device 100 for explanation of the present invention. FIG. 1 shows the prior art, a housing with a “metal cage”.

[0033] A bore 10 is formed in the metal cage 40 .

[0034] The clamping element 20 must be inserted into the “metal cage” from the side and positioned at the top in the 0° position. This makes it possible for the screw element 30 to be inserted through the thread in the clamping element and the bore in the “metal cage”, and this screwing-together can be performed in advance.

[0035] The clamping element 20 is pulled down by virtue of the screw element 30 being rotated further, and is rotated into a 45° position in order to lock. The module is pulled all the way down in the installation bore with the clamping element and brought into the 45° position.

[0036] FIG. 2 is a schematic illustration of a plastics housing device 100 according to an exemplary embodiment of the present invention.

[0037] A top side and a bottom side of the plastics housing device 100 are illustrated in FIG. 2.

[0038] In the illustration of the top side, the clamping element 20 and the screw element 30 are visible, and in the illustration of the bottom side of the plastics housing device 100, the positioning element 50, configured as three spring tabs in FIG. 2, is also visible.

[0039] FIG. 3 is a schematic illustration of a plastics housing device according to an exemplary embodiment of the present invention.

[0040] From top to bottom, FIG. 3 illustrates the following:

[0041] A clamping element 20 is illustrated at the top in FIG. 3. The plastics housing device 100 comprises a single-piece housing base. A circuit board as a carrier for electronic components is likewise illustrated in FIG. 3. FIG. 3 likewise shows a screw element 30 and a housing cover.

[0042] FIG. 4 is a schematic illustration of a plastics housing device according to an exemplary embodiment of the present invention.

[0043] FIG. 4 shows a clamping element which is pressed against hooks 50 in the housing base.

[0044] The first thread turn of the screw element 30 is pressed against the clamping element 20.

[0045] The screw head lies on the housing cover.

[0046] Positioning elements 50 embodied as spring-loaded arms push the screw element 30 upward.

[0047] A rotation of the clamping element 20 is for example prevented in a neutral position.

[0048] FIG. 4 is a schematic illustration of a plastics housing device according to an exemplary embodiment of the present invention, wherein provision is made for hooks, as positioning element, to secure the clamping element.

[0049] The lower illustration in FIG. 4 shows the clamping element in the 0° position.

[0050] FIG. 5 is a schematic illustration of a plastics housing device according to an exemplary embodiment of the present invention.

[0051] FIG. 5 shows two hooks 60 with provisional retaining action.

[0052] FIG. 6 is a schematic illustration of a plastics housing device according to an exemplary embodiment of the present invention.

[0053] FIG. 7 is a schematic illustration of a plastics housing device according to an exemplary embodiment of the present invention.

[0054] FIG. 7 shows the clamping element in a 45° position.

[0055] FIG. 8 is a schematic illustration of a plastics housing device according to an exemplary embodiment of the present invention.

[0056] FIG. 9 is a schematic illustration of a plastics housing device according to an exemplary embodiment of the present invention.

[0057] In the plastics housing device illustrated in FIG. 9, the at least one positioning element 50 is configured as a spring tab or a snap-action hook element.

[0058] FIG. 10 is a schematic illustration of a plastics housing device according to an exemplary embodiment of the present invention.

[0059] In the plastics housing device illustrated in FIG. 10, the at least one positioning element 50 is configured as a helical spring.
