Abstract

Elektrische Schaltgeräte, insbesondere Schütze, weisen einen feststehenden Magnetkern und einen beweglichen Anker auf, wobei der Anker an einem Führungsbauteil befestigt ist. Bei diesen Schaltgeräten mit einem Elektromagnetsystem bzw. einem Magnetantrieb kommt es sehr darauf an, daß der Hub des Ankers, d.h. der Bewegungsweg, den der Anker beim Betätigen des Schaltgerätes von der Ruhestellung bis zum Auftreffen auf den Magnetkern zurücklegt, auf ein genaues Maß eingestellt ist. Dieses Maß läßt sich in der Praxis infolge Fertigungstoleranzen oder im praktischen Gebrauch im Laufe der Zeit durch Veränderung des Hubs, vor allem durch Verschleiß und Abbrand der Kontaktstücke des im Schaltgerät vorhandenen Kontaktsystems, nicht genau einhalten. Um eine Hubverstellung zum richtigen Einstellen sowie zum nachträglichen Anpassen des Magnetantriebes in einfacher Weise zu ermöglichen, wird vorgeschlagen, den Anker mittels eines Mitnehmerbolzens zu befestigen, dessen Enden zylindrisch und koaxial zueinander ausgebildet sind und in Bohrungen des Führungsbauteils gelagert sind, wobei der Mitnehmerbolzen im Bereich zwischen den zylindrischen Enden ein Mehrkantteil aufweist, welches an dem Anker angreift und dessen Umfangsflächen unterschiedliche Abstände zur gemeinsamen Achse der zylindrischen Enden besitzen.Electrical switching devices, in particular contactors, have a fixed magnetic core and a movable armature, the armature being fastened to a guide component. In these switching devices with an electromagnetic system or a magnetic drive, it is very important that the stroke of the armature, i.e. the path of movement that the armature covers when the switching device is actuated from the rest position until it hits the magnetic core is set to an exact dimension. This dimension cannot be maintained in practice due to manufacturing tolerances or in practical use over time by changing the stroke, especially due to wear and tear of the contact pieces of the contact system in the switching device. In order to enable a stroke adjustment for correct setting and for subsequent adjustment of the magnetic drive in a simple manner, it is proposed to fasten the armature by means of a driving pin, the ends of which are cylindrical and coaxial to one another and are mounted in bores of the guide component, the driving pin in the area has a polygonal part between the cylindrical ends, which engages the armature and whose peripheral surfaces have different distances from the common axis of the cylindrical ends.

Description

Die Erfindung bezieht sich auf ein elektrisches Schaltgerät, insbesondere Schütz, welches einen feststehenden Magnetkern und einen beweglichen Anker aufweist, wobei der Anker an einem Führungsbauteil befestigt ist.The invention relates to an electrical switching device, in particular a contactor, which has a fixed magnetic core and a movable armature, the armature being fastened to a guide component.

Bei elektrischen Schaltgeräten der vorbezeichneten Gattung mit einem Elektromagnetsystem bzw. einem Magnetantrieb kommt es sehr darauf an, daß der Hub des Ankers, d.h. der Bewegungsweg, den der Anker beim Betätigen des Schaltgerätes von der Ruhestellung bis zum Auftreffen auf den Magnetkern zurücklegt, auf ein genaues Maß eingestellt ist. In der Praxis läßt sich dieses Maß nicht genau einhalten, was man bisher in Kauf genommen hat. Dies hat verschiedene Gründe. Einmal lassen sich bei der Herstellung des Schaltgerätes gewisse Fertigungstoleranzen nicht vermeiden, die den tatsächlich ausgeführten Hub beeinflussen. Des weiteren kann im praktischen Gebrauch des Schaltgerätes im Laufe der Zeit eine Veränderung des Hubs eintreten, und zwar vor allem durch Verschleiß und durch Abbrand der Kontaktstücke des im Schaltgerät vorhandenen Kontaktsystems. Die Folge ist vor allem auch, daß ein störendes Brummen des Magnetantriebes auftritt.In electrical switching devices of the aforementioned type with an electromagnetic system or a magnetic drive, it is very important that the stroke of the armature, ie the path of movement that the armature travels when the switching device is actuated from the rest position until it strikes the magnetic core, to an exact Dimension is set. In practice, this measure cannot be kept exactly what has been accepted up to now. There are several reasons for this. On the one hand, certain manufacturing tolerances that influence the stroke actually carried out cannot be avoided in the manufacture of the switching device. In addition, a change in the stroke can occur in the course of time in practical use of the switching device, especially as a result of wear and tear and of the contact pieces burning of the contact system in the switchgear. The main consequence is that a disturbing hum of the magnetic drive occurs.

Demgemäß liegt der Erfindung die Aufgabe zugrunde, das elektrische Schaltgerät derart auszugestalten, daß eine Hubverstellung zum richtigen Einstellen sowie zum nachträglichen Anpassen des Magnetantriebes in einfacher Weise möglich ist.Accordingly, the invention has for its object to design the electrical switching device such that a stroke adjustment for correct setting and for subsequent adjustment of the magnetic drive is possible in a simple manner.

Ausgehend von dem zu Anfang erläuterten elektrischen Schaltgerät wird die gestellt Aufgabe erfindungsgemäß dadurch gelöst, daß der Anker mittels eines Mitnehmerbolzens befestigt ist, dessen Enden zylindrisch und koaxial zueinander ausgebildet sind und in Bohrungen des Führungsbauteiles gelagert sind, und daß der Mitnehmerbolzen im Bereich zwischen den zylindrischen Enden ein Mehrkantteil aufweist, welches an dem Anker angreift und dessen Umfangsflächen unterschiedliche Abstände zur gemeinsamen Achse der zylindrischen Enden besitzen. Auf diese Weise ist es möglich, den Hub des Ankers durch einfaches Herausziehen, Drehen und Wiedereinschieben des Mitnehmerbolzens eine Änderung des Hubes herbeizuführen. Dadurch kann auch das unangenehme Brummen des Magnetantriebes vermieden werden.Starting from the electrical switching device explained at the beginning, the object is achieved according to the invention in that the armature is fastened by means of a driving pin, the ends of which are cylindrical and coaxial to one another and are mounted in bores in the guide component, and in that the driving pin is in the region between the cylindrical End has a polygonal part, which engages the armature and the peripheral surfaces have different distances from the common axis of the cylindrical ends. In this way, it is possible to change the stroke of the armature by simply pulling out, turning and reinserting the driver bolt. This also prevents the unpleasant hum of the magnetic drive.

Figur 1 zeigt in vereinfachter perspektivischer Darstellung einen Teil eines elektrischen Schaltgerätes, nämlich ein Magnetsystem bzw. einen Magnetantrieb mit einem Magnetkern 1 und einem Anker 5, wobei in diesem Ausführungsbeispiel sowohl der Magnetkern als auch der Anker je drei Schenkel 2, 3, 4 bzw. 6, 7, 8 aufweisen. Der Magnetanker 5 ist über einen Hub 39 beweglich gehalten und zu diesem Zweck an einem Führungsbauteil 9 befestigt. Das Führungsbauteil ist vereinfacht dargestellt, um das Prinzip deutlicher zu machen. In der Praxis kann das Führungsbauteil in Anpassung an die Gegebenheiten des betreffenden Schaltgerätes anders gestaltet sein. Von Bedeutung ist, daß durch die Befestigung des Magnetankers an dem Führungsbauteil der Hub 39 des Magnetankers bestimmt wird.FIG. 1 shows a simplified perspective illustration of part of an electrical switching device, namely a magnet system or a magnet drive with a magnet core 1 and an armature 5, in this exemplary embodiment both the magnet core and the armature each having three legs 2, 3, 4 or 6, 7, 8 have. The magnet armature 5 is held movably via a stroke 39 and is fastened to a guide component 9 for this purpose. The guide component is shown in simplified form to make the principle clearer. In practice, the guide component can be designed differently to suit the circumstances of the switching device in question. It is important that the stroke 39 of the magnet armature is determined by fastening the magnet armature to the guide component.

Um eine Hubverstellung bzw. ein Einstellen und Anpassen des Magnetantriebs ermöglichen zu können, ist der Magnetanker 5 mittels eines Mitnehmerbolzens 10 an dem Führungsbauteil 9 befestigt. Die beiderseitigen Enden 11 und 12 des Mitnehmerbolzens 10 sind zylindrisch und koaxial zueinander ausgebildet. Diese Enden sind in Bohrungen des Führungsbauteils 9 bzw. in dessen umgreifenden Stegen 37 und 38 gelagert. Wie die Figuren 2 und 3 veranschaulichen, weist der Mitnehmerbolzen 10 im Bereich zwischen den zylindrischen Enden 11, 12 ein Mehrkantteil 13 auf, welches an dem Magnetanker 5 angreift. Zu diesem Zweck ist in dem Magnetanker 5 oder in einem nicht gezeichneten, mit dem Magnetanker fest verbundenen Halteteil eine entsprechende durchgehende Mehrkantöffnung vorgesehen, so daß man den Mitnehmerbolzen 10 von der einen Seite des Führungsbauteils, im vorliegenden Falle von der Außenseite des Steges 38 ausgehend, hindurchstecken kann. Das Mehrkantteil 13 ist im dargestellten Ausführungsbeispiel vorteilhaft im Querschnitt quadratisch ausgebildet. Je nach Bedarf kann dieses Mehrkantteil aber auch im Querschnitt dreieckig, sechseckig, achteckig usw. ausgebildet sein. Von wesentlicher Bedeutung ist nun, daß die Umfangsflächen 40, 41, 42 und 43 des Mehrkantteiles 13 unterschiedliche Abstände 14, 15, 16 und 17 zur gemeinsamen Achse 18 der beiden zylindrischen Enden 11 und 12 besitzen. Nach einem vorteilhaften Ausführungsbeispiel für die Praxis kann der Abstand 14 beispielsweise 3,0 mm, der Abstand 15 3,2 mm, der Abstand 16 3,4 mm und der Abstand 17 3,6 mm betragen. Je nachdem in welcher Lage der Mitnehmerbolzen eingesteckt wird, kann nach diesem Ausführungsbeispiel der Hub 39 zwischen vier Stufen von je 0,2 mm, also um 0,6 mm verändert werden.In order to enable a stroke adjustment or an adjustment and adaptation of the magnet drive, the magnet armature 5 is fastened to the guide component 9 by means of a driver bolt 10. The ends 11 and 12 of the driver pin 10 on both sides are cylindrical and coaxial to one another educated. These ends are stored in bores in the guide component 9 or in its encompassing webs 37 and 38. As FIGS. 2 and 3 illustrate, the driving pin 10 has a polygonal part 13 in the area between the cylindrical ends 11, 12, which engages the magnet armature 5. For this purpose, a corresponding, continuous polygonal opening is provided in the magnet armature 5 or in a holding part (not shown) that is firmly connected to the magnet armature, so that the driver bolt 10 starts from one side of the guide component, in the present case from the outside of the web 38. can put through. The polygonal part 13 is advantageously square in cross section in the illustrated embodiment. Depending on requirements, this polygonal part can also be triangular, hexagonal, octagonal, etc. in cross-section. Essential feature is that the peripheral surfaces 40, 41, 42 and 43 of the polygonal member 13 at different distances 14, 15, 16 and 17 to the common axis 1 8 11 and 12 have the two cylindrical ends. According to an advantageous practical example, the distance 14 can be, for example, 3.0 mm, the distance 15 3.2 mm, the distance 16 3.4 mm and the distance 17 3.6 mm. Depending on the position in which the driving pin is inserted, the stroke 39 can be changed between four steps of 0.2 mm, ie by 0.6 mm, according to this exemplary embodiment.

Vorteilhafterweise hat das eine zylindrische Ende 11 des Mitnehmerbolzens 10 einen kleineren Durchmesser als die Abmessungen des Mehrkantteiles 13, während das andere zylindrische Ende 12 einen größeren Durchmesser aufweist und gleichzeitig als Anschlag in der Halterung dient und den richtigen Sitz des Mitnehmerbolzens 10 anzeigt. In weiterer Ausgestaltung der Erfindung ist an der Stirnfläche 19 des Mitnehmerbolzens 10 eine Markierung zum Kenntlichmachen der gewählten Stellung des Mitnehmerbolzens vorgesehen, wie insbesondere Figur 4 veranschaulicht. Die Markierung kann z.B. aus Ziffern bestehen, die je nach Einsatz einer feststehenden Pfeilspitze 44 am Steg 38 (Figur 1) gegenüberstehen.Advantageously, the one cylindrical end 11 of the driving pin 10 has a smaller one Diameter than the dimensions of the polygonal part 13, while the other cylindrical end 1 2 has a larger diameter and at the same time serves as a stop in the holder and indicates the correct fit of the driving pin 10. In a further embodiment of the invention, a marking is provided on the end face 19 of the driving pin 10 to indicate the selected position of the driving pin, as illustrated in particular in FIG. 4. The marking can, for example, consist of numbers which, depending on the use, face a fixed arrow tip 44 on the web 38 (FIG. 1).

In weiterer Ausgestaltung der Erfindung können die Flächen 40 bis 43 des Mehrkantteiles 13 leicht ballig nach außen gewölbt ausgebildet sein. Ferner ist es vorteilhaft, die Flächen 20, 21 des Mitnehmerbolzens 10 beiderseitig des Mehrkantteiles 13 bis hin zu den beiderseitigen zylindrischen Enden 11, 12 nach diesen Enden zu leicht abgeschrägt zu gestalten. Auf diese Weise ist es möglich, nicht nur eine Einstellung in den beiden Richtungen entsprechend dem Hub 39, sondern auch eine Anpassung in den entsprechenden Querrichtungen zu bewirken.In a further embodiment of the invention, the surfaces 40 to 43 of the polygonal part 13 can be curved slightly outward. Furthermore, it is advantageous to design the surfaces 20, 21 of the driving pin 10 on both sides of the polygonal part 13 to the cylindrical ends 11, 12 on both sides too slightly beveled after these ends. In this way, it is possible to effect not only an adjustment in the two directions in accordance with the stroke 39, but also an adjustment in the corresponding transverse directions.

Zur Verdeutlichung zeigen die Figuren 5 und 6 noch einen Längsschnitt bzw. einen Querschnitt durch ein vereinfacht dargestelltes elektrisches Schaltgerät, welches in einem Gehäuse 32 mit Gehäuseoberteil oder Deckel 33 mit Festkontaktanschlußschienen 22 und 23 und darauf befindlichen Festkontaktstücken 24, 25 ausgerüstet ist. Mit diesen Festkontaktstücken 24, 25 wirkt eine Kontaktbrücke 26 zusammen, die bewegliche Kontaktstücke 27, 28 trägt und die über Kontaktdruckfedern 29, 30 gegenüber dem Führungsbauteil 9 und damit zu dem Magnetanker 5 gehalten ist. Das Führungsbauteil 9 kann noch mit einem durch den Gehäusedeckel 33 hindurchragenden Betätigungsknopf 31 versehen sein. Ferner sind gemäß Figur 6 Rückholfedern 34, 35 vorgesehen, die bei nichteingeschaltetem Zustand des Schaltgerätes das Führungsbauteil 9 und den Magnetanker 5 in Ruhelage halten. In bekannter Weise ist das Magnetsystem noch mit einer eingesetzten Spule 36 versehen.For the sake of clarity, FIGS. 5 and 6 also show a longitudinal section or a cross section through a simplified electrical switching device, which is located in a housing 32 with an upper housing part or cover 33 with fixed contact connection rails 22 and 23 and thereon Fixed contact pieces 24, 25 is equipped. A contact bridge 26 interacts with these fixed contact pieces 24, 25, which carries movable contact pieces 27, 28 and which is held via contact pressure springs 29, 30 relative to the guide component 9 and thus to the magnet armature 5. The guide component 9 can also be provided with an actuating button 31 protruding through the housing cover 33. Return springs 34, 35 are also provided according to FIG. 6, which hold the guide component 9 and the magnet armature 5 in the rest position when the switching device is not switched on. In a known manner, the magnet system is also provided with an inserted coil 36.

Das oben erläuterte Verstellen bzw. Einstellen kann in einfacher Weise dadurch bewirkt werden, daß man nach Lösen des Gehäusedeckels 33 bzw. -oberteils den Magnetanker 5 mit den verbundenen Bauteilen aus dem Gehäuse heraushebt, den Mitnehmerbolzen 10 herauszieht und durch Drehen um die Achse 18 in der gewünschten Stellung wieder einschiebt. Das Zusammensetzen des Schaltgerätes geht dann mit einfachen Handgriffen wieder auf umgekehrtem Wege vonstatten.The above-described adjustment or adjustment can be effected in a simple manner by lifting the magnet armature 5 with the connected components out of the housing after loosening the housing cover 33 or upper part, pulling out the driving bolt 10 and rotating it about the axis 18 in the desired position again. The assembly of the switchgear is then carried out in the opposite way with simple steps.
