ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a switchgear cabinet with a frame stand that has vertical frame profiles, which on at least one frame stand side of the frame stand a lateral casing is attached to two vertical frame profiles associated with the side, a mounting wall is spaced apart from the lateral casing facing an interior of the switching cabinet, a cable installation space is formed between the mounting wall and the lateral casing, and the mounting wall is detachably fastened to the frame stand by retaining elements.
2. Description of Related Art
A switchgear cabinet is known from German Patent Reference DE 195 07 728 C1. In this case, a mounting plate is used as a mounting wall, which is spaced apart from a rear lateral casing of the switchgear cabinet. In order to insert the mounting plate into the frame stand, guide rails are built into the base region of the switchgear cabinet. The guide rails extend in the direction of the switchgear cabinet depth. With slide elements at its bottom, the mounting plate is placed on the mounting rails and can be slid on them.
A similar apparatus is known from German Patent Reference DE 195 11 639 C1. The mounting plate is slid from the side of the switchgear cabinet, such as in the direction of the switchgear cabinet width.
The prior art also includes mounting rails of the kind disclosed by German Patent Reference DE 196 29 422 C1. The mounting rail has a mounting wall with retaining elements bent away from its longitudinal sides. The mounting rail can be fastened by the retaining elements to two vertical frame profiles of one side of a switchgear cabinet.
SUMMARY OF THE INVENTION
One object of this invention is to provide a switchgear cabinet of the type mentioned above but in which cables or cable supports can be routed and arranged in an organized manner and in which there are numerous possibilities for cable routing.
This object is achieved with a mounting wall disposed between the vertical frame profiles of the frame stand side. An edge cable feedthrough is formed between at least one of the vertical sides of the mounting wall and the associated vertical frame profile. The mounting wall can be moved on the retaining elements horizontally in relation to the vertical frame profiles.
In the vicinity of the edge cable feedthroughs according to this invention, cables can be routed between the switchgear cabinet interior and the cable installation space formed between the mounting wall and the lateral casing. The positioning of the mounting wall and thus the edge cable feedthroughs can also be varied in accordance with the installation circumstances in the switchgear cabinet interior and the quantities of cable to be accommodated.
In one preferred embodiment of this invention, the mounting wall is disposed between horizontal frame profiles of the associated frame stand side of the frame stand. An edge cable feedthrough is formed between at least one of the horizontal sides of the mounting wall and the associated horizontal frame profile. The mounting wall can be moved on the retaining elements in the vertical direction in relation to the vertical frame profiles. In this arrangement, edge cable feedthroughs can also be provided at the horizontal edges of the mounting wall. In particular, with a corresponding formation and dimensioning of the mounting wall, a cable feedthrough region can be produced that bypasses the mounting wall.
For an organized accommodation and routing of the cable, it is possible for the mounting wall to have a flat wall section, which has a grid of cable connector mounts and/or screw receptacles spaced apart from one another in a uniform pattern.
In order to be able to simply achieve the variation of the mounting position, it is possible for the mounting wall, in the vicinity of its two vertical sides, to be fastened to the vertical frame profiles of the frame stand side by the retaining elements, and the retaining elements or the mounting wall to have a number of fastening receptacles led into them, which are associated with the various fastening positions of the mounting wall.
In particular, the retaining elements can have a plate-shaped fastening section that is screw-connected to the mounting wall. The fastening section is adjoined by a flange, which rests against the associated profile side of the vertical frame profile facing the switchgear cabinet interior. At least one hook is punched out from the flange, is bent toward the profile side, and is hooked into fastening receptacles of the profile side. The hooks allow the mounting wall to be simply and precisely hung on the frame stand. The hooks thus form a stable support.
In another embodiment, the retaining elements are formed as mounting rails, which extend between the two vertical frame profiles of the frame stand side and are affixed to them.
In practical applications, it is possible to attach two or more switchgear cabinets to one another. The interior of a switchgear cabinet which is adjacent can be accessed through the adjoining side. For access protection, it is possible to make this access difficult to achieve. Thus, it is possible for the mounting wall, on one of its vertical sides, to adjoin the associated vertical frame profile. In this manner, the mounting wall can be attached, for example, to the front frame profile of the adjoining side. Unauthorized access from the front is thus reliably prevented when the cabinet door is open.
The cable routing possibilities are increased if the mounting wall has at least one cable feedthrough opening, which produces a connection between the switchgear cabinet interior and the cable installation space formed between the lateral casing and the mounting wall.
