Description
Die Erfindung betrifft eine Anordnung zur Stromschienenbefestigung für mehrphasige Schaltgeräte, insbesondere für Schütze, nach dem Oberbegriff von Anspruch 1.The invention relates to an arrangement for busbar mounting for multi-phase switching devices, in particular for contactors, according to the preamble of claim 1.
Stromschienen in mehrphasigen elektrischen Schaltgeräten weisen an ihrem äußeren Ende eine Anschlussklemme auf und sind mit ihrem inneren Ende unmittelbar oder mittelbar mit einem feststehenden Kontaktstück verbunden, das mit einem beweglichen Kontaktstück in und außer Verbindung tritt. Es ist bekannt, Stromschienen im Schaltgerätegehäuse durch Einpressen- oder Umspritzen (DE 19904355 A1), durch Verkleben (DE 10036350 A1), durch Verschrauben mit Muttergewinde im Schaltgerätegehäuse (DE 29604726 U1), in Gewindeplatten (DE 19814410 A1 und EP 0948009 A2) oder in den Stromschienen (DE 3232173 C2), durch Niederhalten mittels dafür vorgesehener Gehäuseteile (EP 645792 A1), durch Einbetten (DE 10061394 A1) oder durch Vernieten zu befestigen.Busbars in multiphase electrical switching devices have at their outer end a terminal and are connected with its inner end directly or indirectly with a fixed contact piece, which enters and out of communication with a movable contact piece. It is known busbars in the switchgear housing by press-fitting or encapsulation (DE 19904355 A1), by gluing (DE 10036350 A1), by screwing with female thread in the switchgear housing (DE 29604726 U1), in threaded plates (DE 19814410 A1 and EP 0948009 A2) or in the busbars (DE 3232173 C2), by holding down by means provided for housing parts (EP 645792 A1), by embedding (DE 10061394 A1) or by riveting.
Die Nachteile der bekannten Anordnungen zur Stromschienenbefestigung sind der hohe technologische Aufwand an Ausrüstung, Werkzeugen und Arbeitszeit zur Realisierung der Befestigung und die teils unmögliche, teils nur bedingt mögliche und teils aufwändige Demontage der Stromschienen. Beispielsweise hat ein Kunde, der den vom Hersteller empfohlenen Austausch von verbrauchten Kontakten gegen neue Kontakte selbst vomehmen will, bei einem dreiphasigen Schütz mit schraubbefestigten Stromschienen wenigstens sechs Schrauben mit ihren sechs Sicherungselementen zu lösen sowie wieder zu befestigen. Kleben der Stromschienen erfordert Vorbehandlung der Flächen und Aushärtzeiten. Verklebte Teile ziehen einen erhöhten Aufwand beim Recycling nach sich.The disadvantages of the known arrangements for busbar fastening are the high technological complexity of equipment, tools and working time for the realization of the attachment and the sometimes impossible, partly only partially possible and sometimes expensive disassembly of the busbars. For example, a customer who wants to take the recommended by the manufacturer exchange of used contacts against new contacts themselves, in a three-phase contactor with screw-mounted busbars at least six screws with their six security elements to solve and re-attach. Gluing the busbars requires pretreatment of the surfaces and curing times. Glued parts are more expensive to recycle.
Der Erfindung liegt daher die Aufgabe zugrunde, eine einfache Montage und Demontage der Stromschienen zu ermöglichen.The invention is therefore based on the object to enable easy assembly and disassembly of the busbars.
Ausgehend von einer Anordnung der eingangs genannten Art wird die Aufgabe erfindungsgemäß durch die Merkmale des unabhängigen Anspruches gelöst, während den abhängigen Ansprüchen vorteilhafte Weiterbildungen der Erfindung zu entnehmen sind.Based on an arrangement of the type mentioned, the object is achieved by the features of the independent claim, while the dependent claims advantageous developments of the invention can be found.
Mit den geradlinig ausgebildeten Führungselementen und den Aufnahmebohrungen im Schaltgerätegehäuse, den Durchgangsbohrungen in den Stromschienen und je einem Steckkamm pro Anschlussseite wird eine Anordnung zur Stromschienenbefestigung geschaffen, die mit wenigen translatorischen Fügebewegungen zu einer stabilen Festlegung der Stromschienen führt. Die Befestigung der Stromschienen ist damit leicht zu automatisieren. Die erfindungsgemäße Anordnung erfordert weder ein Muttergewinde in den Stromschienen oder im Schaltgerätegehäuse noch Gewindeplatten und verzichtet auf die für Schraubverbindungen erforderlichen Sicherungselemente. Durch das Fehlen von Eisenteilen erfolgt keine negative magnetische Beeinflussung der Stromleitung über die Stromschienen. Sowohl das abschließende Befestigen als auch das Lösen aller Stromschienen einer Anschlussseite erfolgt mit einem Handgriff durch Einstecken bzw. Herausziehen des Steckkamms in die bzw. aus den Durchgangs- und Aufnahmebohrungen. Bei entferntem Schaltgeräte-Gehäusedeckel sind für die werkzeuglose Montage bzw. Demontage der Stromschienen lediglich zwei einfache und schnell auszuführende Handgriffe pro Anschlussseite erforderlich. Der Steckkamm lässt sich gemessen an kleineren Schrauben und Sicherungselementen wesentlich besser handhaben. Der Steckkamm kann zur Erleichterung des Recyclings aus regenerierbarem Material gespritzt werden. Der eingesetzte Steckkamm aus isolierendem Formstoff erleichtert wesentlich die Einhaltung der geforderten Luft- und Kriechstrecken. Diese Problematik spielt eine zunehmende Rolle durch den Trend zu Schaltgeräten mit immer kleineren Abmessungen. Die Oberfläche des Verbindungssteges des Steckkammes kann in geschickter Weise zum Aufbringen von Hinweisen an den Kunden genutzt werden.With the rectilinear guide elements and the mounting holes in the switchgear housing, the through holes in the busbars and a comb per connection side an arrangement for busbar attachment is created, which leads with a few translational joining movements to a stable fixing of the busbars. The attachment of the busbars is thus easy to automate. The arrangement according to the invention requires neither a female thread in the busbars or in the switching device housing nor threaded plates and waives the security elements required for screw. Due to the absence of iron parts there is no negative magnetic influence on the power line over the busbars. Both the final fixing and the release of all busbars of a connection side is done with a handle by inserting or pulling out of the comb in and out of the passage and mounting holes. When the switchgear housing cover is removed, only two simple and quickly executed handles per connection side are required for tool-free installation or removal of the busbars. The comb can be measured much better to handle smaller screws and securing elements. The comb can be injected from regenerable material to facilitate the recycling. The plug-in comb made of insulating molding material makes it much easier to comply with the required clearances and creepage distances. This problem plays an increasing role due to the trend towards switching devices with ever smaller dimensions. The surface of the connecting web of the comb can be used in a clever way for applying clues to the customer.
Zweckmäßigerweise klemmen die Steckkämme mit ihren Steckzapfen in den Durchgangsbohrungen oder/und werden durch einen Schaltgeräte-Gehäusedeckel niedergehalten.Conveniently, the plug-in combs clamp with their plug-in pin in the through holes or / and are held down by a switchgear housing cover.
Eine zweckmäßige Ausgestaltung des Steckkammes besteht in einer zylindrischen oder prismatischen Ausbildung der Steckzapfen, Durchgangs- und Aufnahmebohrungen, beispielsweise mit kreisförmigem oder polygonalem Querschnitt Ein vorteilhafte Ausgestaltung besteht in längsgeschlitzten Steckzapfen zur Herstellung der kraft- und formschlüssigen Verbindung zwischen den Durchgangs- und den Aufnahmebohrungen. Fasen an den freien Enden der Steckzapfen erleichtern das Einführen in die Durchgangs- und die Aufnahmebohrungen.An expedient embodiment of the plug-in comb is in a cylindrical or prismatic formation of the plug, passage and receiving bores, for example, with circular or polygonal cross-section An advantageous embodiment is longitudinally slotted plug-in pin for producing the non-positive and positive connection between the passage and the mounting holes. Chamfers on the free ends of the plug-in pins facilitate insertion into the through-holes and the receiving bores.
Eine vorteilhafte Ausgestaltung des Steckkammes besteht darin, Ausgleichsschlitze im Verbindungssteg zum besseren Toleranzausgleich der Abstände zwischen den Aufnahmebohrungen vorzusehen. Zur besseren Handhabung ist eine griffförmige Ausbildung des Verbindungssteges von Vorteil.An advantageous embodiment of the plug-in comb is to provide compensation slots in the connecting web for better tolerance compensation of the distances between the receiving bores. For better handling a handle-shaped design of the connecting web is advantageous.
Um die in den Führungselementen eingesetzten Stromschienen vor dem Einsetzen des Steckkammes gegen Herausfallen zu sichern, sind die Stromschienen mit Noppen ausgestattet, wodurch die Stromschienen beim Einführen in die Führungselemente in klemmende Verbindung mit diesen treten.To secure the busbars used in the guide elements before inserting the comb against falling out, the busbars are equipped with knobs, whereby the busbars when inserted into the guide elements in jamming connection with these occur.
Ein vorteilhafte Weiterbildung der Anordnung besteht darin, die Phasentrennwände des Schaltgerätegehäuses, d.h. die phasentrennenden Zwischenwände, mit Aufnahmeschlitzen auszustatten, die den eingesteckten Steckkamm über seinen Verbindungssteg parallel zur Anschlussrichtung abstützen und somit zu einer Erhöhung der zulässigen Zug- und Druckkräfte an den Anschlussklemmen beitragen. Dabei greifen zweckmäßigerweise der mit Ausgleichsschlitzen versehene Verbindungssteg und die mit den Aufnahmeschlitzen ausgestatteten Phasentrennwände kreuzweise ineinander.An advantageous development of the arrangement is to equip the phase separation walls of the switchgear housing, ie the phase-separating partitions, with receiving slots which support the inserted comb over its connecting web parallel to the direction of connection and thus contribute to an increase of the permissible tensile and compressive forces at the terminals. Expediently, the connecting web provided with compensating slots and the phase dividing walls equipped with the receiving slots intersect one another in a crosswise manner.

In der Zeichnung ist die Anordnung zur Stromschienenbefestigung mit den zur Darstellung der Erfindung wesentlichen Teilen eines mehrpoligen Schaltgerätes 2 in Form eines dreipoligen Schützes dargestellt. Das Schaltgerät 2 ist von einem Schaltgerätegehäuse 4 umgeben, von dem in der Zeichnung nur das Gehäuseoberteil dargestellt ist. Das Schaltgerätegehäuse 4 wird, wie in Fig. 1 dargestellt, frontseitig von einem abnehmbaren Gehäusedeckel 6 abgeschlossen. Pro Stromphase ist je eine zugehende und eine abgehende Stromschiene 8 in dem Schaltgerätegehäuse 4 festgelegt. Jede Stromschiene 8 weist an ihrem äußeren Ende eine in den jeweiligen Anschlussraum 10 reichende Anschlussklemme 12 auf und ist an ihrem inneren Ende mit einem feststehenden Kontaktstück 14 versehen. Die zu einer Stromphase gehörenden Stromschienen 8 werden in üblicher Weise durch eine nicht dargestellte Kontaktbrücke elektrisch verbunden bzw. getrennt, wobei die feststehenden Kontaktstücke 14 mit an der Kontaktbrücke befestigten beweglichen Kontaktstücken in und außer Verbindung treten.In the drawing, the arrangement for busbar mounting is shown with the essential parts for illustrating the invention of a
In dem Schaltgerätegehäuse 4 sind, wie in Fig. 2 gezeigt, auf jeder Anschlussseite für jede Stromphase paarweise gegenüberstehend nutenförmige Führungselemente 16 ausgebildet. Zwischen die Führungselemente 16 wird der plattenförmige Mittelteil 18 der Stromschienen 8 so weit eingeschoben, bis er in der in Fig. 1 und 3 dargestellten Montageposition der Stromschiene 8 an einer Abschlussfläche 20 der Führungselemente 16 anliegt. Jede Stromschiene 8 weist eine Durchgangsbohrung 22 auf, die sich in der Montageposition jeweils mit einer im Schaltgerätegehäuse 4 ausgebildeten Aufnahmebohrung 24 deckt. Die Stromschienen 8 sind am Mittelteil 18 mit randseitig ausgeprägten Noppen 25 versehen, die beim Einführen der Stromschienen 8 in die Führungselemente 16 zu einer Klemmwirkung führen, die ausreicht, die Stromschienen 8 beim Transport während der Fertigung des Schaltgerätes 2 am Herausgleiten aus den Führungselementen 16 zu hindern.In the switchgear housing 4, groove-
Zu der Befestigungsanordnung gehört weiterhin ein Steckkamm 26 aus isolierendem Formstoff für jede Anschlussseite. Der Steckkamm 26 weist für jede Stromphase einen rundzylindrischen Steckzapfen 28 auf. Die zu einer Anschlussseite gehörenden Steckzapfen 28 sind miteinander über einen plattenförmigen Verbindungssteg 30 verbunden. Von dem Verbindungssteg 30 ragen in eine Richtung die Steckzapfen 28 ab. Der Verbindungssteg 30 ist mit einem Handgriff 32 ausgestattet, der den abragenden Steckzapfen 28 gegenüberliegt.To the mounting arrangement further includes a
Zur Festlegung der Stromschienen 8 in ihrer Montageposition werden die Steckkämme 26 mit ihren Steckzapfen 28 durch die Durchgangsbohrungen 22 der Stromschienen 8 klemmend in die Aufnahmebohrungen 24 des Schaltgerätegehäuses 4 geschoben. Zur Erleichterung des Einsteckens sind die Steckzapfen 28 an den freien Enden mit Einführfasen 34 ausgeführt. Um Toleranzen zwischen den geometrischen Abständen der Aufnahmebohrungen 24 und der Steckzapfen 28 gut ausgleichen zu können, ist der Verbindungssteg. 30 mit gemäß den Darstellungen in der Zeichnung nach unten offenen Ausgleichsschlitzen 36 zwischen den Steckzapfen 28 ausgestattet. Die Steckkämme 26 werden in ihrer Montageposition zusätzlich durch den aufgesetzten Gehäuse - deckels 6 niedergehalten.To fix the
Das Schaltgerätegehäuse 4 weist längs verlaufende, durchgehende innere Phasentrennwände 38 auf. In den Phasentrennwänden 38 sind auf jeder Anschlussseite gemäß den Darstellungen in der Zeichnung nach oben offene Aufnahmeschlitze 40 ausgebildet, die mit den Aufnahmebohrungen 24 in jeweils einer Ebene liegen. Die Aufnahmeschlitze 40 nehmen den Verbindungssteg 30 des eingeführten Steckkammes 26 auf. Dabei umgreifen einerseits die den Aufnahmeschlitzen 40 benachbarten Wandteile der Phasentrennwände 38 beidseitig den Verbindungssteg 30 und dazu im rechten Winkel anderseits die den Ausgleichsschlitzen 36 benachbarten Teile des Verbindungssteges 30 beidseitig die Phasentrennwände 38. Auf diese Weise gehen die Steckkämme 26 mit dem Schaltgerätegehäuse 4 kreuzförmige Verbindungen ein.The switchgear housing 4 has longitudinal, continuous
Durch die teils kraftschlüssige, teils formschlüssige Verbindung der Stromschienen 8 im Schaltgerätegehäuse 4 über die zusammenwirkenden Elemente Mittelteile 18 und Führungselemente 16 einerseits sowie die zusammenwirkenden Elemente Aufnahmebohrungen 24, Steckzapfen 28 und Durchgangsbohrungen 22 anderseits wird eine einfache, sichere und wieder problemlos lösbare Befestigungsanordnung realisiert. Die Steckzapfen 28 werden auf Scherung beansprucht, insbesondere bei anschlussseitigen Zugbelastungen. Der Querschnitt der Steckzapfen 28 ist in Verbindung mit dem auszuwählenden Werkstoff so zu bemessen, dass er den zu erwartenden Beanspruchungen standhält. Der Steckkamm 26 ist durch die dargestellte geometrische Ausbildung weitgehend erhaben gegenüber Toleranzen. Unterschiede des Schaltgerätegehäuses 4 in den Phasenabständen im Zehntel-Millimeter-Bereich werden durch den Steckkamm 26 problemlos bewältigt. Um die Aufmerksamkeit des demontierenden und montierenden Kunden auf die Steckkämme 26 zu lenken, empfiehlt sich für diese Teile eine deutlich andere Farbgestaltung gegenüber dem Schaltgerälegehäuse 4.Due to the partially non-positive, partially positive connection of the
Die vorliegende Erfindung ist nicht auf die vorstehend beschriebenen Ausführungsformen beschränkt, sondern ümfässt auch alle im Sinne der Erfindung gleichwirkenden Ausführungsformen. So lässt sich die Erfindung beispielsweise noch in der Weise ausgestalten, dass zur Bewirkung einer elastischen Klemmkraft die Steckzapfen entlang ihrer Längsachse einfach oder kreuzweise geschlitzt sind.The present invention is not limited to the embodiments described above, but also encompasses all embodiments which have the same effect in the sense of the invention. Thus, for example, the invention can be configured in such a way that, to effect an elastic clamping force, the plug-in pins are slotted in a simple or crosswise manner along their longitudinal axis.
