Definitions
- the invention relates to a subrack with two side walls, with at least one cover plate and with at least one base plate, the cover plate and the base plate being fastened between the side walls and the cover plate and the base plate having a right-angled upstanding bevel.
- Subracks such as those used to hold plug-in modules with electrical and electronic components, have long been known in industrial electronics.
- such a rack consists of two side walls and four module rails, which are screwed with their end faces on both sides to the inner surfaces of the punched-out side walls made of aluminum.
- a cover plate and a base plate as well as a rear wall can turn the subrack into a closed housing, from the open front side of which the subassemblies are inserted on inserted guide rails.
- the modules have partial front panels that 2 are leaned against the two front module rails and screwed on at the top and bottom. Pull-in and pull-out devices that connect to the module rails complete the subrack.
- the module rails required for subracks have - to meet all the requirements for fastening the partial front plates and the guide rails - more or less elaborately designed profiles, they are therefore made of extruded aluminum. Complicated tools are required to manufacture these modular rails, and their manufacture is therefore expensive. Attempts to manufacture the modular rails by repeatedly folding strips of sheet steel have so far failed because the unavoidable, large bending radii do not allow the sharp-edged transitions of adjacent surfaces. This is where the invention intervenes.
- module rails are provided for connecting the side walls, which are each composed of two U-rails of different widths, which lie one inside the other.
- side walls which are each composed of two U-rails of different widths, which lie one inside the other.
- protruding sheet metal lugs on the inner rail which engage in slots in the web of the outer, wider U-rail (DE-OS 195 23 964).
- a known, inexpensive to manufacture subrack has two side walls which can be plugged together with the top part and the bottom part.
- the sides have meandering edge punchings, the fingers of which engage in trapezoidal, punched-out bulges, which are provided on inwardly projecting folds of the ceiling and floor (DE 295 02 404);
- Front and rear cross bars are formed by multiple bends from the floor and ceiling parts.
- the object of the invention is to design a module rack that can be produced at particularly low cost.
- a known subrack as described at the outset is used, whereby it is solved by the following constructive measures, namely: An angle bar is attached to the cover plate or to the bottom plate parallel to the fold, the angle bar has a wide leg and a narrow leg bent at a right angle, the narrow leg carries a series of threaded holes, the long edge of the bevel stands on the inside of the wide leg, the narrow leg stands with its outer edge on the outside of the cover plate or bottom plate, which has a fold a series of holes aligned with the threaded holes, and connecting means are provided along the longitudinal edge of the bevel and the outer edge.
- the cover plate, the base plate and the angle strip are expediently made of corrosion-protected steel plate of the same thickness. This serves to simplify production. 4
- At least some of the holes in the fold are designed as fitting holes. Positioning pins which protrude from the rear of the partial front panels engage in these.
- the wide leg of the angle bar advantageously forms a protruding projection in which equidistant rectangular openings are provided in series.
- This projection (usually referred to as "roof"), together with the rectangular openings, serves as an abutment for the pull-in and pull-out devices provided on the assemblies.
- a first row of prongs protrude as connecting means along the outer edge of the narrow leg, which engage in a first row of receptacles in the cover plate or base plate.
- a second row of tines protrude along the edge of the cover plate and the base plate, which engage in a second row of receptacles in the wide leg of the angle bar.
- the row of tines is advantageously arranged slightly offset in relation to the row of receptacles, so that a good, reliable clamping connection is achieved when the parts are joined together.
- the strength of the connection can be increased further by pressing down the top of the tines seated in the receptacles using a tool, such as during a riveting process.
- an adhesive alone can also be provided as the connecting means. This eliminates the production of tines and receptacles when punching the components to be connected, so that additional costs can be reduced. Any other known fastening method can also be used for the connection along the outer edge of the narrow leg and the bevel of the top and bottom plates. 5
- cover plate and the base plate expediently have tabs which protrude at right angles on their side edges and are provided with fastening holes which are aligned with screw holes on the longitudinal edges of the side walls. This enables the top and bottom plates to be attached to the sides of the rack in a simple manner.
- a distance can be provided between the bevel and the narrow leg, as a result of which a closed channel of rectangular cross section is formed between the cover plate or the base plate and the angle bar. This considerably increases the flexural rigidity of the front edges of the cover plate and base plate provided with the angle strips. The rear edges are provided with a further bevel.
- the cover part and the base part have a further angle strip on their rear edge and an embodiment which correspond to that of their front end face.
- cover plate with the cover part and the bottom plate with the bottom part are made in one piece and cover part and bottom part have at their rear edge a further angle bar and a training which corresponds to that of the front end face is particularly advantageous.
- Figure 1 shows a rack according to the invention, in a narrow embodiment, in a perspective view, on a scale reduced to about half.
- Fig. 2 shows a one-piece bottom plate of the subrack
- Fig. 1; 3 shows a floor panel according to FIG. 2 and an associated angle bar, exploded apart;
- Fig. 4 is a front corner of the floor panel of FIG. 2 and
- the subrack 1 shown in FIG. 1 is composed of two parallel side walls 2 and 3, a cover plate 4 and a cover part 5 and a base plate 6 and a (not visible) base part 7. All parts are made of corrosion-protected steel sheet with the same thickness of about one and a half millimeters.
- the cover plate 4, the cover part 5, the bottom plate 6 and the bottom part 7 sit between the two side walls 2 and 3 and are fastened there by means of cap screws 8.
- the ceiling and the bottom of the rack 1 are each formed in two parts. These four components are each identical. Bent mounting flanges 9 are used on the end face of the side walls 2 and 3 for mounting on a frame (not shown).
- Both the cover plate 4 and the base plate 6 are provided on their front faces with a narrow bend 10 - see FIG. 2 - which protrude at right angles from the plane of cover plate 4 and base plate 6. This fold has a series of equidistant holes 11.
- FIGS. 2 to 4 show an embodiment in which the base plate 6 and the base part 7 form a common, one-piece component for the base of the subrack 1.
- the ceiling can also be designed in this way.
- An angle bar 12 is attached to the cover plate 4 and the bottom plate 6, which is parallel to the relevant bend 10.
- This made of sheet steel, long angle bar 12 has a wide leg 13 and a narrow leg 14 which is bent at right angles.
- the angle bar 12 extends 7 over the entire width of the cover plate 4 or the bottom plate 6 - see FIG. 3.
- the narrow leg 14 carries a series of threaded holes 15 which are aligned with the holes 11 of the fold 10.
- the angle bar 12 is arranged so that the edge 10 of the cover plate 4 or the bottom plate 6 stands with its longitudinal edge 16 on the inside 17 of the wide leg 13 (Fig. 2). At the same time, the narrow leg 14 of the angle bar 12 stands with its outer edge 18 on the outside 19 (see FIG. 1) of the cover plate 4 or the base plate 8, whereby a sharp-edged corner is achieved.
- Connecting means 20 are provided along the longitudinal edge 16 of the fold 10 of the cover plate 4 and the base plate 6 and along the outer edge 18 of the narrow leg 14 of the angle strip 12.
- a series of equidistantly arranged prongs 21 protrude as connecting means 20 along the outer edge 18 of the narrow leg 14 of the angle strip 12, which engage in a series of receptacles 22 in the cover plate 4 or in the base plate 6.
- the fold 10 of the cover plate 4 and the base plate 6 carries a second row of prongs 21 which are inserted into a second row of receptacles 22 which are located in the wide leg 13 of the angle strip 12.
- the rows of tines 21 are intrinsically small compared to the rows of receptacles 22, i.e. by a fraction of a millimeter, offset from one another, whereby a clamping connection is achieved when the angle bar 12 and cover plate 4 or base plate 6 are put together.
- the tines 21 and the receptacles 22 have a rectangular cross-section and bevels 23 are provided on the heads of the tines 21 as an insertion aid.
- a suitable adhesive (not shown) can take the place of the prongs 21 and receptacles 22.
- the wide leg 13 of the angle bar 12 forms a protrusion 24 (FIG. 1) referred to as a roof, in which equidistantly arranged rectangular openings 25 are provided.
- Both the cover plate 4 and the base plate 6 have at their side edges n perpendicularly projecting tabs 26 (see FIGS. 1 and 4) which are provided with fastening holes 27 which are aligned with screw holes 28 on the longitudinal edges of the side walls 2 and 3.
- a distance 29 is provided between the fold 10 of the cover plate 4 and the base plate 6 on the one hand and the narrow leg 14 of the angle strip 12 on the other hand.
- a closed channel 30 with an approximately rectangular cross section is formed between the cover plate 4 or the base plate 6 and the angle bar 12.
- the bottom plate 6 and the bottom part 7 can - see Figures 2 and 3 - be made in one piece; the same applies to the cover plate 6 and the cover part 7.
- the cover parts 5 and the bottom parts 7 also have a further bevel 31 on their rear edge, which carries threaded holes 32 for fastening plug-in connectors and / or backplanes which is on the rear of the subrack are arranged.
- Screw holes (in 2 and 3) distance 10 channel chamfer threaded holes and openings
