Definitions

  • the invention relates to a switch cabinet with at least two profiled rails, on the bottom at the sides, which provide a supporting surface, and a bottom plate that can be laid on and fastened to them.
  • the bottom plate is generally connected to the supporting surface of the profiled rails using a clamp especially provided for this purpose.
  • the clamp usually has a screw which takes care of the necessary contact pressure between the bottom plate and the contact surface.
  • This object is solved for a switch cabinet of the known kind in that the supporting surfaces of the profiled rails are provided with a track of punched holes, and the bottom plate can be attached using at least one joining element that can be inserted in a hole in the track of punched holes, whereby this joining element damages the inside wall of the hole, by means of which it produces a positive locking.
  • the bottom plate is attached to the supporting surface of the profiled rails only via one joining element, which is easy to insert from above into a hole in the track of punched holes.
  • a joining element that produces a positive locking with the inner wall of the hole, a sufficient and always uniform fastening force is ensured.
  • the damage to the inner wall of the hole when the joining element is inserted results in an earth contact between the profiled rail, the joining element and the bottom plate. In turn, this simplifies the installation of the bottom plate, because no additional hole needs to be provided for the connection to earth.
  • the attachment of the bottom plate takes little space, so that a bottom entry can be created that is larger than with conventional attachment.
  • the joining element can be formed as a screw with a self-cutting thread.
  • a screw fulfils all requirements placed on the joining element; the screw can be simply inserted from above into a hole in the track of punched holes and held there in its position.
  • the width of the bottom plate can correspond to the distance between the opposing profiled rails plus the section of the supporting surface of the profiled rails, each of which faces towards the interior of the switch cabinet and each of which is arranged next to the track of punched holes.
  • edge legs facing away from the interior of the switch cabinet, can be formed on the sides of the bottom plate perpendicular to the profiled rails, leaving open the edge area of the bottom plate that lies on the supporting surface.
  • installation of the bottom plate is further simplified, because the folded-down legs represent a fastening aid, because an alignment of the bottom plate that is essentially parallel to the track of punched holes is achieved.
  • the width of the edge legs can correspond to the distance between the profiled rails that lie across from one another. This measure results in an additional fixing in place of the bottom plate, because the latter is already fixed in place within the bottom area of the switch cabinet by the edge legs, which point down and extend between the profiled rails.
  • the edge legs can extend downwards at an angle of 90°. Particularly when several bottom plates are arranged next to one another, in this way it can be ensured that the legs of the bottom plates do not interfere with one another.
  • the self-securing joining element and the bottom plate can be coated with zinc. This measure has proven satisfactory in application, also particularly regarding the connection to earth.
  • three bottom plates can be arranged on the supporting surface, parallel to one another. Because it is possible to work with shorter bottom plates, the installation is simplified, in turn, because these shorter bottom plates are easier to handle.
  • the separate bottom plates can be arranged next to one another at a predetermined distance.
  • Such a gap between the separate bottom plates makes it possible, for example, to feed a cable into the interior of the switch cabinet, without measures that require effort being necessary.
  • FIG. 1 is a three-dimensional view of a section of a lower profiled rail of a switch cabinet, a piece of a bottom plate attached to the lower profiled rail, and a joining element;
  • FIG. 2 is a three-dimensional representation of the bottom plate area of a switch cabinet with cables fed through.
  • FIG. 1 a detail of the bottom of an interior of an exemplary switch cabinet is shown in a three-dimensional view. Specifically, a section of a profiled rail 1 , a bottom plate 2 and a joining element 3 connecting the rail 1 to the bottom plate 2 are shown.
  • the profiled rail 1 has a horizontal supporting leg 4 , which has two profiled legs 5 , 6 folded so that they extend up at a right angle.
  • the supporting surface 7 is bent off from the inner profiled leg 6 , which faces the interior of the switch cabinet, in such a way that it extends perpendicularly to the profiled leg 6 and parallel to the supporting leg 4 , towards the profiled leg 5 .
  • the supporting surface 7 is provided with a track of punched holes 8 that runs parallel to the profiled leg 5 .
  • the separate holes 8 are preferably formed to be round and arranged at regular distances from one another.
  • the track of punched holes 8 is arranged in the section of the supporting surface 7 that faces the profiled leg 5 .
  • the profiled rail 1 can be formed in a single piece with a side wall of the switch cabinet, whereby the profiled leg 5 would represent a section of the side wall in this case, or as a frame rail that is independent from the side wall and on which a side wall of the cabinet can then be attached.
  • the bottom plate 2 essentially consists of a rectangular plate 9 that is horizontally inserted into the interior of the switch cabinet and with its edge sections 10 that face towards the profiled rails 1 lying on the supporting surface 7 .
  • the dimensions of the bottom plate 2 are such that the edge area 10 of the bottom plate 2 extends on the supporting surface 7 only up to the track of punched holes 8 , so that this track continues to be freely accessible.
  • the bottom plate 2 is provided with folded edge legs 11 on the edges of the rectangular plate 9 that extend perpendicularly to the supporting surface 7 , in one piece.
  • These edge legs 11 are formed by buckling a part of the bottom plate 2 , whereby the edge leg 11 is bent down at an angle of about 90° from the rectangular plate 9 , facing away from the interior of the switch cabinet.
  • the edge leg 11 does not extend across the entire edge surface of the rectangular plate 9 , but instead over the area formed between the profiled legs 6 that lie across from one another, so that the edge area 10 lying on the supporting surface 7 is left open.
  • the edge leg 11 is preferably formed so that it is somewhat shorter than the profiled leg 6 , so that, in the installed state, a gap results between the edge leg 11 and the bottom of the supporting leg 4 .
  • a fixing in place and orientation of the bottom plate 2 is already achieved during the installation by the edge legs 11 , which extend between the opposing profiled rails 1 of the cabinet.
  • the edge legs 11 which extend between the opposing profiled rails 1 of the cabinet.
  • it is attached to this one with a joining element 3 .
  • this joining element 3 is a screw with a self-cutting thread, i.e., the screw is inserted into one of the holes 8 in the track of punched holes and cuts a mating thread in the hole 8 with a thread formed on the screw. In this process, the surface of the hole 8 is damaged. After the fastening, the screw head lies partially on the bottom plate 2 and thus sees to additional pressure force.
  • FIG. 2 the lower area of an installed switch cabinet is represented, whereby three bottom plates 14 , 15 and 16 are arranged next to one another.
  • the bottom plates 14 , 15 , 16 in this case extend between the opposing profiled rails 1 of the cabinet.
  • the separate bottom plates 14 , 15 , 16 can have different widths and can be arranged at a predefined distance from one another.
  • the bottom plate 14 directly bordering on a switch cabinet wall, and the bottom plate 15 , running parallel to the first, are arranged with regard to one another in such a way that an open bottom area-results between the two bottom plates 14 and 15 .
  • this open bottom area 46 is used for feeding through cables 17 , which have been fed through to the required point in the interior of the switch cabinet beneath the bottom plates 14 and 15 .
  • the cables 17 can be fed underneath the rail 18 provided on the bottom plate 14 and directly to the intended place, using guides 19 attached to this rail.
  • the size of the bottom plates 14 , 15 and 16 and the distance between them can be freely selected, this allows, in a very simple way, cable penetrations to be formed at any place within the interior of the switch cabinet. In this case, the resulting open areas, if required, can be additionally sealed using suitable measures.
  • each bottom plate 14 , 15 , and 16 is arrested on each profiled rail 1 via a joining element 3 . In this way, a connection to ground is ensured for all elements.
