Abstract

A control box arrangement including at least one control box which is sub-divided, or can be sub-divided, by vertical wall sections with a horizontal sub-division, into a plurality of cuboid compartments surrounded on all sides. A variable structural design of compartments, particularly functional compartments, for example for low voltage systems, is obtained by providing wall sections including lateral wall sections adapted to the same or different compartment heights, adapted rear wall sections embodied as mounting plates, and horizontal partition bottoms, in order to produce a plurality of horizontal compartments, in the form of pigeonholes, arranged one above the other.

the vertical wall sections including side wall sections (20) and rear wall sections embodied as mounting plates (40), wherein heights of the side wall sections and the mounting plates are matched to a spacing dimension of rows of fastening holes of the vertical frame legs or vertical mounting rails positioned in the control box arrangement.

2. The control box arrangement as recited in claim 1, wherein a bus bar compartment for a main rail system extends vertically over an entire height of the control box interior, positioned inside behind the compartments (5) in a depth direction of the control box arrangement.

3. The control box arrangement as recited in claim 2, wherein fronts of the compartments (5) have respective compartment doors (16) adapted to heights of the fronts.

4. The control box arrangement as recited in claim 3, wherein a front door that extends over all of the compartments (5) is in front of the compartments (5), each of which can have a respective compartment door (16).

5. The control box arrangement as recited in claim 4, wherein a divider strip (15) with a U-shaped cross section is positioned in front of the front edge of the compartment-dividing floors (30), with an open side oriented toward the front and free ends of side legs positioned in a same plane as a front plane of the frame legs (11).

6. The control box arrangement as recited in claim 5, wherein the side wall sections (20) in an upper corner region close to a vertical edge has bent hook elements (32) oriented away from the compartment interior and have downward-oriented securing protrusions adapted to openings in the rows of fastening holes.

7. The control box arrangement as recited in claim 6, wherein in an upper edge region each of the side wall sections (20) is first bent diagonally inward and upward at an obtuse angle parallel to an edge and are then bent diagonally outward and upward.

8. The control box arrangement as recited in claim 7, wherein the side wall sections (20) have a horizontal arrangement of holes at least in a lower edge region.

9. The control box arrangement as recited in claim 8, wherein mounting angles (70) attach the compartment-dividing floor (30) along the side wall sections (20), the mounting angles have a vertical leg (71) and a horizontal leg (72) and are attached to the vertical frame legs (11), the vertical mounting rails and/or the side wall sections (20) with a respective compartment-dividing floor is fastened to the opposing horizontal legs (72) of the mounting angles (70).

10. The control box arrangement as recited in claim 9, wherein the mounting angles (70) protrude beyond the inner edge of the vertical frame legs (11) and a width of the compartment-dividing floors (30) is at most as wide as a distance between the opposing vertical frame legs (11) in a width direction of the control box arrangement.

11. The control box arrangement as recited in claim 10, wherein the compartment-dividing floors (30) extend in the depth direction to the mounting plates (40) and the side wall sections (20) extend to the plane of the mounting plates (40) and are attached to vertical mounting rails or extend in the depth direction to and are attached to the rear vertical frame legs.

12. The control box arrangement as recited in claim 11, wherein the compartment-dividing floors (30) have in a rear edge region a cutout (32) that is broken out or can be broken out, through which the vertical distributing rails with a cover that prevents them from being touched are routed.

13. The control box arrangement as recited in claim 1, wherein fronts of the compartments (5) have respective compartment doors (16) adapted to heights of the fronts.

14. The control box arrangement as recited in claim 1, wherein a front door that extends over all of the compartments (5) is in front of the compartments (5), each of which can have a respective compartment door (16).

15. The control box arrangement as recited in claim 1, wherein a divider strip (15) with a U-shaped cross section is positioned in front of a front edge of the compartment-dividing floors (30), with an open side oriented toward the front and free ends of side legs positioned in a same plane as a front plane of the frame legs (11).

17. The control box arrangement as recited in claim 1, wherein in an upper edge region each of the side wall sections (20) is first bent diagonally inward and upward at an obtuse angle parallel to an edge and are then bent diagonally outward and upward.

18. The control box arrangement as recited in claim 1, wherein the side wall sections (20) have a horizontal arrangement of holes at least in a lower edge region.

19. The control box arrangement as recited in claim 1, wherein mounting angles (70) attach the compartment-dividing floor (30) along the side wall sections (20), the mounting angles have a vertical leg (71) and a horizontal leg (72) and are attached to the vertical frame legs (11), the vertical mounting rails and/or the side wall sections (20) with a respective compartment-dividing floor is fastened to the opposing horizontal legs (72) of the mounting angles (70).

20. The control box arrangement as recited in claim 1, wherein the compartment-dividing floors (30) extend in a depth direction to the mounting plates (40) and the side wall sections (20) extend to the plane of the mounting plates (40) and are attached to vertical mounting rails or extend in the depth direction to and are attached to the rear vertical frame legs.

21. The control box arrangement as recited in claim 1, wherein the compartment-dividing floors (30) have in a rear edge region a cutout (32) that is broken out or can be broken out, through which the vertical distributing rails with a cover that prevents them from being touched are routed.

22. The control box arrangement as recited in claim 1, further comprising a plurality of mounting angles each including a vertical leg attachable to one of the side wall sections or the vertical frame legs, and each including a horizontal leg extending from the vertical leg into the interior of the first or second control box and attachable to one of the horizontal compartment-dividing floors.

23. The control box arrangement as recited in claim 1, wherein a second plurality of the side wall sections encloses outer sides of the control box arrangement, and further comprising continuous side walls covering the second plurality of side walls.

16. The control box arrangement as recited in 1, wherein the side wall sections (20) in an upper corner region close to a vertical edge has bent hook elements (32) oriented away from the compartment interior and have downward-oriented securing protrusions adapted to openings in the rows of fastening holes.

24. A control box arrangement comprising:

a first control box including a first plurality of vertical frame legs;

a second control box including a second plurality of vertical frame legs and connected to the first control box;

a plurality of the vertical wall sections forming a vertical wall section of both a first compartment of the first control box and a second compartment of the second control box;

the vertical frame each including rows of fastening holes to which the vertical wall sections are mounted; and

the vertical wall sections including side wall sections, and rear wall sections embodied as mounting plates, wherein a height of each of the compartments is a multiple of a height of the side wall sections and the mounting plates.

25. The control box arrangement as recited in claim 24, wherein a bus bar compartment for a main rail system extends vertically over an entire height of the control box interior, positioned inside behind the compartments (5) in a depth direction of the control box arrangement.
