Schienenkanal für SchienenverteilerRail channel for rail distributors
Die Erfindung betrifft einen Schienenkanal nach dem Oberbegriff des Anspruches 1.The invention relates to a rail channel according to the preamble of claim 1.
Schienenverteiler, die auch als Linienverteiler bekannt sind, bestehen aus einem Schienenkanal mit darin befestigten Stromschienen, Abgangstellen und Abgangskästen und dienen zur Verteilung elektrischer Energie, insbesondere in Fabrikhallen und Gebäuden in den Verbraucher oft gewechselt werden müssen.Rail distributors, which are also known as line distributors, consist of a rail channel with busbars fastened therein, outgoing points and outgoing boxes and serve to distribute electrical energy, particularly in factories and buildings, in which consumers often have to be replaced.
Ein derartiger Schienenverteiler mit einem Schienenkanal aus Blech ist in der EP 0335756 Bl in den Figuren 7 und 8 gezeigt.Such a rail distributor with a rail channel made of sheet metal is shown in EP 0335756 B1 in FIGS. 7 and 8.
Der Schienenkanal besteht aus zwei Gehäusehälften, wobei die obere auf die untere aufrolliert ist, d.h. die obere Gehäusehälfte ist in den Kantenbereichen um die unteren Gehäusehäfte gebogen. Zusätzlich sind seitlich Vertiefungen in das Material gedrückt, damit die Verwindungssteifigkeit erhöht wird. Zur Erhöhung der Verwindungsstefigkeit kann zwar eine höhere Blechdicke gewählt werden, was aber mit höheren Kosten verbunden ist.The rail channel consists of two housing halves, the upper one being rolled onto the lower one, i.e. the upper half of the housing is bent around the lower half of the housing in the edge areas. In addition, depressions are pressed into the material on the side to increase torsional rigidity. A higher sheet thickness can be selected to increase the torsional strength, but this is associated with higher costs.
Dieser Schienenverteiler hat den Vorteil, daß er relativ flach gebaut werden kann, z.B im Vergleich zu dem in der DE-U 66 07 93 gezeigten Ausführungsform.This rail distributor has the advantage that it can be built relatively flat, for example in comparison to the embodiment shown in DE-U 66 07 93.
Zur Befestigung des Schienekanals oder bei der Befestigung von Teilen an dem Schienenkanal bieten sich nur wenig Befestigungsmöglichkeiten, ohne daß die IP-Schutzart beeinträchtigt wird, z.B. durch Bohrungen. Ferner ist es nur mit zusätzlichem Aufwand möglich, eine Verbesserung der leitenden Verbindung zwischen den Gehäusehälften zu erreichen.There are only a few fastening options for fastening the rail channel or when fastening parts to the rail channel without the IP protection class being impaired, for example by drilling. Furthermore, it is only possible with additional effort To achieve improvement in the conductive connection between the housing halves.
Aufgabe der Erfindung ist es, einen Schienenkanal nach dem Oberbegriff des Anspruches 1 derart auf kostengünstige Art weiterzubilden, daß einerseits eine Verbesserung in Bezug auf die Verwindungssteifigkeit erreicht wird und andererseits eine Verbesserung in bezug auf die Befestigungsmöglichkeiten von oder an Teilen und in bezug auf die PE-Verbindung beider Gehäusehälften erreicht wird.The object of the invention is to develop a rail channel according to the preamble of claim 1 in such a cost-effective manner that on the one hand an improvement in terms of torsional rigidity is achieved and on the other hand an improvement in terms of the fastening options of or on parts and in relation to the PE -Connection of both housing halves is achieved.
Die Aufgabe der Erfindung wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst, während in den Unteransprüchen besonders vorteilhafte Weiterbildungen der Erfindung gekennzeichnet sind.The object of the invention is achieved by the characterizing features of claim 1, while particularly advantageous developments of the invention are characterized in the subclaims.
Durch die Erfindung wird in kostengüstiger Weise die Steifigkeit, insbesondere die Verwindungssteifigkeit erhöht. Durch die Erfindung kann aber auch die erforderliche Blechdicke gesenkt werden.The invention increases the rigidity, in particular the torsional rigidity, in a cost-effective manner. The invention also allows the required sheet thickness to be reduced.
Anhand der Zeichnung, in der ein Ausführungsbeispiel dargestellt ist, sollen die Erfindung, weitere Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile näher beschrieben und erläutert werden.The invention, further refinements and improvements of the invention and further advantages are to be described and explained in more detail with reference to the drawing, in which an exemplary embodiment is shown.

Fig.8a-c Darstellungen des Herstellungsverfahren der Nietverbindung.Fig.8a-c representations of the manufacturing process of the rivet connection.
Die Fig. 1 zeigt den Schienenkanal 1, in dem die Stromschienen 2 in einem Isolierprofil 3 eingebettet sind. In bekanter Weise sind Abgangsstellen 4 für Abgangskästen vorhanden.1 shows the rail channel 1, in which the busbars 2 are embedded in an insulating profile 3. In a well-known manner, there are outlet points 4 for outlet boxes.
Wie noch näher beschrieben wird, sind an den Seiten jeweils eine Reihe von fluchtenden Nietverbindungen 5 angeordnet, die Zusammen mit den Gehäusehälften dem Schienenkanal seine besondere Steifigkeit -in bezug auf Verwinden oder Durchhähngen- verleihen.As will be described in more detail, a series of aligned rivet connections 5 are arranged on the sides, which together with the housing halves give the rail channel its particular rigidity with respect to twisting or sagging.
Die Fig. 2 zeigt beide Gehäusehälften des Schienenkanals l, die auseinandergezogen dargestellt sind.2 shows both housing halves of the rail channel 1, which are shown pulled apart.
Eine der Gehäusehälten besteht aus einem Doppel-T-Profil 6, während die andere Gehäusehälfte aus einem Hut-Profil 7 besteht, wie näher in der Figuren 3 und 4 zu sehen ist.One of the housing halves consists of a double-T profile 6, while the other housing half consists of a hat profile 7, as can be seen in more detail in FIGS. 3 and 4.
Durch das Doppel-T-Profil 7 erhält der Schienenkanal l eine besondere Steifigkeit. Das Doppel-T-Profil 6 ist aus einem Blechabschnitt gebogen, wobei die Kanten zusätzlich mit einem Bördel 8 versehen sind.Due to the double-T profile 7, the rail channel 1 is particularly rigid. The double-T profile 6 is bent from a sheet metal section, the edges additionally being provided with a flange 8.
Die andere als U-Profil 7 geformte Gehäusehälfte wird bündig zwischen den Seitenabschnitten 9 angeordnet. Das Hut-Profil weist einen Basisabschnitt 10, ein senkrecht hierzu angeordneten Wandabschnitt 11, einen wieder parallen zu Basisabschnitt 10 angeordneten Befestigungsabschnitt 12 zur Befestigung mit den Nietverbindunden 5 und einen senkrecht in Richtung des Befestigungsabschnittes 10 gebogenen Verstärkungsabschnittes 13. Das Hut-Profil, auch als Unterschale bezeichnet, bildet die Form einen Wanne, in der das Isolierprofil 3 eingebettet ist.The other half of the housing, shaped as a U-profile 7, is arranged flush between the side sections 9. The hat profile has a base section 10, a wall section 11 arranged perpendicularly thereto, a fastening section 12 again arranged parallel to the base section 10 for fastening to the rivet connections 5 and a reinforcing section 13 bent perpendicularly in the direction of the fastening section 10. The hat profile, also as Called the lower shell, the shape forms a trough in which the insulating profile 3 is embedded.
Das Doppel-T-Profil 6 weist Durchbrüche für Isolierstoffteile 17 mit Stecköffnungen 16 und Verschlußschiebern auf. Die Durchbrüche 18 sind etwas größer als die Isolierstoffteile 17, wodurch ein Fenster 20 entsteht, so daß eine PE-Verbindung zwischen Abgangskasten und Schiehenkasten trotz lackierter Oberschale (Doppel-T-Profil 6) möglich ist.The double-T profile 6 has openings for insulating parts 17 with plug openings 16 and slide gates. The openings 18 are somewhat larger than the insulating parts 17, which creates a window 20, so that a PE connection between the tap-off unit and the box unit is possible despite the coated upper shell (double-T profile 6).
Vorzugsweise ist das Fenster zwischen der Abgangsstelle und dem Seitenabschnitt 9 im Bereich des Befestigungsabschnittes 12 angeordnet. Der Erdungskontakt des Abgangskastens greift auf die metallisch blanken Stelle des Befestigungsabschnittes 12.The window is preferably arranged between the departure point and the side section 9 in the region of the fastening section 12. The grounding contact of the tap-off box engages the bare metal location of the fastening section 12.
Die Bördelnietung (Nietverbindung 5) verbindet die elektrisch lackierte Oberschale mit der metallisch blanken Unterschale (Hut-Profil 7) zwecks Erdung durch starkes Verguetschen beim Nieten.The flanged rivet (rivet connection 5) connects the electrically painted upper shell to the bare metal lower shell (hat profile 7) for the purpose of earthing through heavy grouting during riveting.
Die PE-Verbindung der Schienenkästen bzw. einkelnen Schienenkanäle l wird durch einen Verbindungsflansch 19 und der blanken Unterschale erreicht.The PE connection of the rail boxes or single rail channels 1 is through a connecting flange 19 and bare lower shell reached.
Durch die Bördelnietung ist es möglich in einfacher Weise Zubehör, z.B. mit gewindefurchenden Schrauben, zu Befestigen. Mit der Bördelvernietung ist eine direkte Verschraubung des Schienenkanals mit Distanzbuchsen möglich.Flanging riveting makes it possible to easily add accessories, e.g. to be fastened with self-tapping screws. With the flanged riveting, the rail channel can be screwed directly to the spacer bushings.
Mit der Nietverbindung 5 erreicht mann eine hohe IP-Schutzart. Zwischen den Abgangsstellen sind jeweils zwei Nietverbindungen 5 angeordnet.The rivet connection 5 achieves a high degree of IP protection. Two rivet connections 5 are arranged between the departure points.
In der Fig. 8a sind die Ober- und Unterschale im Bereich des Befestigungsabschnittes 12 gezeigt. Die mit 21 gekennzeichte Einführbohrung kann entfallen, wenn ein ausreichend spitzer Stempel verwendet wird, der von oben gedrückt wird. Hierdurch entsteht, die in Fig. 8b gezeigte Öffnung mit den Bördelrändern 22, 23. Durch einen von unten drückenden zweiten Stempel 24 werden die Bördelränder 22, 23 geweitet und flach gedrückt, so daß die in den Figuren 8c und 6 gezeigte Form entsteht.8a shows the upper and lower shells in the area of the fastening section 12. The insertion hole marked with 21 can be omitted if a sufficiently pointed punch is used which is pressed from above. This results in the opening shown in FIG. 8b with the flange edges 22, 23. The flange edges 22, 23 are widened and pressed flat by a second punch 24 pressing from below, so that the shape shown in FIGS. 8c and 6 is produced.
An den Seitenabschnitten 9 sind auf der Ebene des Hut-Profiles 7 Befestigungsausbrüche 25 für die Befestigung von Abgangs- oder anderen Kästen mittels in die Befestigungsausbrüche 25 greifenden Befestigungskrallen vorhanden. On the side sections 9, at the level of the hat profile 7, there are fastening cutouts 25 for the attachment of outgoing boxes or other boxes by means of fastening claws which reach into the attachment openings 25.
