A device for fastening a support rail on frame legs and mounting panels of a switchgear cabinet. The frame legs have two fastening sides which extend vertically with respect to each other and respectively have a row of fastening holes. Each mounting panel has a row of fastening holes and a folded support strip in an area of a lateral edge. The support rail has on both ends fastening elements which are used for connecting a frame leg or a mounting panel. Assembly of the support rail is considerably simplified and improved by the design of the ends of the support rail and by the use of clamping plates with clamping screws.

A device for attaching busbars of square or rectangular cross section on a support rail using electrically non-conducting support elements, which can be connected with the support rail and form a busbar receptacle adapted to the cross section of the busbar. With a simple fastener, assembly is considerably simplified because two post-shaped supports per busbar can be attached as support elements on the support rail, wherein spacing between the supports is matched to the width of the busbar and a height is matched to the thickness of the busbar. A base plate is arranged between the two supports, which insulates the busbar receptacle against the support rail and which is captively held between the holders. The ends of the supports facing away from the support rail can be closed by a strip.

Operating housing

A control cabinet with an open bottom, which is enclosed by legs of a frame and can be closed off by individual bottom plates which can be placed side-by-side. The individual bottom plates rest with their short sides on a support shoulder of the facing frame legs and are connected with these frame legs. The bottom plates have an edge that is twice bent along at least one long side, wherein sealing strips seal the abutting long sides of adjacent bottom plates and where cables are introduced through cutouts in the bottom. Individual insertion and assured sealing of the individual cables, together with extensive adaptation and expansion possibilities is achieved with at least a portion of the bottom plates having cutouts spaced along the long side with the edge. Cable bushings which have stepped, offset bushing pieces with different interior diameters are insertable into the cutouts.

Control cabinet

A control cabinet with a rack composed of a plurality of horizontal and vertical frame pieces, enclosed by a plurality of wall elements and a cabinet door, where a mounting plate, which has sliders with guide receptacles on their undersides, can be fastened parallel to a rear wall element. Each frame piece has two adjacent sides which are disposed perpendicularly to each other and have identical rows of fastening receivers. The two adjacent sides of each frame piece form an inner edge oriented towards an interior of the control cabinet. At least one of the horizontal frame pieces comprises a depth brace and a guide rail with a guide bar disposed parallel to the depth brace. In the course of inserting the mounting plate into the rack the guide receptacles of the sliders receive the guide bars of the guide rails and the sliders are displaceable on the guide bars. The expense for parts and assembly for guiding the mounting plate is reduced without impairing the fastening possibilities on the rack where the guide rails with their guide bars are formed as one piece with the depth braces, and where horizontal inner edges of the depth braces abut against the vertical inner edges of the vertical frame pieces at a vertical distance to the horizontal inner edges of the horizontal frame pieces.

Housing for a command panel system used to monitor and control work

A rack for a control cabinet comprising a plurality of frame pieces which are connected to each other in the area of the rack corners. A quickly and easily assembled rack with high torsional stiffness is created where the front horizontal and vertical frame pieces as well as the rear horizontal and vertical frame pieces are miter-cut on both ends and fixedly welded together to form a front and rear frame. The frame pieces used as depth braces are closed off on both ends by fastening plates provided with at least two fastening screw receptacles. Correspondingly distributed through-bores are cut in the corner areas of the frame. In each corner area of the frame, a cover plate is fastened on the frame by fastening screws. The fastening screws are inserted into fastening bores of the cover plates and screwed through the through-bores of the frame into the fastening screw receptacles of the fastening plates connected to the depth braces.
