Housing for receiving an electrical or electronic functional assembly

1. A housing for receiving an electrical or electronic functional module, comprising:

a first housing element having a first surface section and at least one first connecting section arranged on the first surface section;

a second housing element having a second surface section and at least one second connecting section arranged on the second surface section, the first housing element and the second housing element being connectable to each other via the at least one first connecting section and the at least one second connecting section; and

an intermediate element arrangeable between the at least one first connecting section and the at least one second connecting section in order to connect the first housing element and the second housing element, the intermediate element having at least one functional device configured to provide an additional function independent of the connection of the at least one first connecting section and the at least one second connecting section,

wherein the first housing element and the second housing element are identical parts,

wherein the at least one functional device comprises a mounting device configured to fasten the housing to a wall,

wherein the intermediate element comprises a body arrangeable between the at least one first connecting section and the at least one second connecting section, and

wherein the mounting device comprises a skirt, on an outside of the housing, that areally covers at least in sections the at least one first connecting section and the at least one second connecting section.

2. The housing according to claim 1 , wherein the at least one first connecting section comprises a first strut projecting from the first surface section and/or the at least one second connecting section comprises a second strut projecting from the second surface section.

3. The housing according to claim 1 , wherein the first surface section has a quadrangular shape and one said first connecting section arranged at each corner of the first surface section, and/or

wherein the second surface section has a quadrangular shape and one said second connecting section arranged at each corner of the second surface section.

4. The housing according to claim 1 , further comprising panel elements which form side walls of the housing and are held between the first housing element and the second housing element by interlocking when the first housing element and second housing element are connected to each other.

5. The housing according to claim 1 , wherein the body is connectable by interlocking to the at least one first connecting section and/or the at least one second connecting section.

6. The housing according to claim 1 , further comprising a fastening flange projecting from the skirt, the fastening flange comprising a fastening point configured to fasten the housing to the wall.

7. The housing according to claim 1 , wherein the skirt, on the outside of the housing, areally covers the at least one first connecting section or the at least one second connecting section along at least an entire height of the at least one first connecting section or the at least one second connecting section, respectively, in a height direction.

8. The housing according to claim 1 , where the first surface section and the second surface section each have a rectangular shape located in a plane defined by spatial directions X and Y.
