Description

Die vorliegende Erfindung betrifft ein elektromagnetisches Schaltgerät, insbesondere Schütz mit einem in einem Gehäuse untergebrachten Schaltmagneten, mit im Gehäuse befestigten festen Kontaktstücken und mit mit diesen durch den Anker des Schaltmagneten in und ausser Eingriff bringbaren, an einem Kontaktträger angebrachten, beweglichen Kontaktstücken und mit mindestens einem zwischen dem Anker des Schaltmagneten und dem im Gehäuse des Schaltgerätes in Hubrichtung des Ankers verschiebbar geführten Kontaktträger wirksamen Uebersetzungshebel.The present invention relates to an electromagnetic switching device, in particular a contactor with a switching magnet accommodated in a housing, with fixed contact pieces fastened in the housing and with movable contact pieces attached to a contact carrier, which can be brought into and out of engagement with the armature of the switching magnet, and with at least one effective translation lever between the armature of the switching magnet and the contact carrier which is displaceably guided in the stroke direction of the armature in the housing of the switching device.

Aus der DE-AS 1.237.667 ist ein elektromagnetisches Schaltgerät der eingangs erwähnten Art bekannt. Bei diesem Schaltgerät ist die Zugkraftkurve des Magneten an die Kraftbedarfskurve des Kontaktsystems dadurch angepasst, dass die Bewegung des Ankers durch eine Kurvenbahn auf das Kontaktsystem übertragen wird. Die Kurvenbahn ist längs dem Betätigungsende eines die Magnetkraft auf das Kontaktsystem übertragenden und diese verstärkenden Uebersetzungshebels angeordnet. Der Anker des Elektromagneten schiebt über die Kurvenbahn das Betätigungsende des Uebersetzungshebels beim Anziehen des Elektromagneten senkrecht zur Hubrichtung des Ankers. Das durch diesen rechteckig abgewinkelten, im Kniebereich ortsfest gelagerten Uebersetzungshebel betätigbare Kontaktsystem wird so in die Schliesstellung gebracht. Die Oeffnung der Kontaktstücke des Schaltgerätes erfolgt nach Unterbrechung der Erregerspannung des Elektromagneten durch die auf das Kontaktsystem wirkende Rückstellfeder des elektromagnetischen Schlatgerätes aber erst nach Freigabe des Uebersetzungshebels. Der Uebersetzungshebel stützt sich in der eingeschalteten Stellung des Schaltgerätes und auch am Anfang einer Ausschaltbewegung mit einem sehr flachen Bereich der Kurvenbahn auf den Anker. Somit hängt die Unterbrechungsgeschwindigkeit der Kontaktstücke auch von allfälligen, den Anker vom Uebersetzungshebel trennenden, zusätzlichen, in der Beschreibung nicht erwähnten Elemeten ab. Ein weiterer Nachteil dieses elektromagnetischen Schaltgerätes besteht darin, dass die Kurvenbahn sehr genau und mit entsprechend hohem Aufwand ausgebildet werden muss, um die gewünschte Kontaktstückbewegung zu erreichen. Ausserdem wirken die Verschiebekräfte des mit der Kurvenbahn versehenen Uebersetzungshebels senkrecht auf die Hubrichtung des Ankers. Aus diesem Grunde muss auch die Ankerführung über die gewünschte Genauigkeit der Bewegung des Uebersetzungshebels verfügen, was wiederum mit Kosten verbunden ist. Dieses elektromagnetische Schaltgerät braucht ausserdem auch viel Platz, insbesondere die Ankopplungsstelle zwischen dem Uebersetzungshebel und dem Kontaktsystem. Die Montage des Schaltgerätes ist ebenfalls kompliziert und mit bedeutenden Kosten verbunden.From DE-AS 1.237.667 an electromagnetic switching device of the type mentioned is known. In this switching device, the traction force curve of the magnet is adapted to the force demand curve of the contact system in that the movement of the armature is transmitted to the contact system by means of a curved path. The cam track is arranged along the actuating end of a transmission lever which transmits the magnetic force to the contact system and reinforces it. The armature of the electromagnet pushes the actuating end of the transmission lever perpendicular to the stroke direction of the armature when the electromagnet is tightened via the cam track. The contact system which can be actuated by this rectangularly angled transmission lever, which is fixed in the knee area, is brought into the closed position. The contact pieces of the switching device are opened after the excitation voltage of the electromagnet is interrupted by the return spring of the electromagnetic switching device acting on the contact system, but only after the transmission lever has been released. The translation lever is supported on the armature in the switched-on position of the switching device and also at the beginning of a switching-off movement with a very flat area of the cam track. The speed of interruption of the contact pieces thus also depends on any additional elements which do not separate the armature from the transmission lever and are not mentioned in the description. Another disadvantage of this electromagnetic switching device is that the cam track has to be designed very precisely and with a correspondingly high outlay in order to achieve the desired contact piece movement. In addition, the displacement forces of the transmission lever provided with the cam track act perpendicular to the stroke direction of the armature. For this reason, the Anchor guide have the desired accuracy of the translation lever movement, which in turn is associated with costs. This electromagnetic switching device also requires a lot of space, especially the coupling point between the transmission lever and the contact system. The assembly of the switchgear is also complicated and involves significant costs.

Aufgabe der vorliegenden Erfindung ist es, ein elektromagnetisches Schaltgerät der eingangs erwähnten Art zu entwickeln, das aus für eine einfache automatische Montage geeigneten, eine kompakte, platzsparende Anordnung ermöglichenden Teilen besteht, das lageunabhängig betriebssicher funktioniert und wirtschaftlich vorteilhaft ist.The object of the present invention is to develop an electromagnetic switching device of the type mentioned at the outset, which consists of parts which are suitable for simple automatic assembly and which enable a compact, space-saving arrangement, which functions reliably in any position and is economically advantageous.

Die gestellte Aufgabe ist dadurch gelöst, dass der Uebersetzungshebel mit seinem einen Ende am ortsfesten Gehäuse und mit seinem anderen Ende am Kontaktträger mindestens in Hubrichtung des Ankers in der Bewegungsebene des Uebersetzungshebels schwenkbar und verschiebbar abgestützt ist und dass der Mittelbereich des Uebersetzungshebels am Anker drehbar gelagert und in Hubrichtung des Ankers geführt ist und dass zwischen dem Kontaktträger und dem daran in Hubrichtung verschiebbar geführten Anker mindestens eine den Anker vom Kontaktträger wegdrückende Feder vorhanden ist. Dadurch, dass der Uebersetzungshebel mit seinem Mittelbereich nur am Anker drehbar befestigt und mit seinen beiden Enden verschiebbar und schwenkbar abgestützt ist, sind die Teile des Schaltgerätes durch einfaches Ineinanderstecken montierbar. Der Anker ist in platzsparender Weise am Kontaktträger verschiebbar. Die zwischen dem Kontaktträger und dem daran verschiebbaren Anker liegende Feder sorgt für ein lageunabhängiges Funktionieren des Schaltgerätes und dafür, dass die beiden Enden des Uebersetzungshebels auf den diese stützenden Auflageflächen ständig unter Federdruck aufliegen. Die einfache Ausbildung der Teile und deren einfache Montierbarkeit bieten wirtschaftliche Vorteile.The object is achieved in that the translation lever is pivotally and displaceably supported with its one end on the stationary housing and with its other end on the contact carrier at least in the lifting direction of the armature in the plane of movement of the translation lever, and that the central region of the translation lever is rotatably mounted on the armature and is guided in the stroke direction of the armature and that at least one spring pushing the armature away from the contact carrier is present between the contact carrier and the armature displaceably guided thereon in the stroke direction. The fact that the transmission lever with its central region is only rotatably fastened to the armature and with its two ends is slidably and pivotably supported, the parts of the switching device can be assembled by simply plugging one into the other. The armature can be moved on the contact carrier in a space-saving manner. The spring located between the contact carrier and the displaceable armature ensures that the switching device functions in a position-independent manner and that the two ends of the translation lever rest constantly on the supporting surfaces supporting them under spring pressure. The simple design of the parts and their ease of assembly offer economic advantages.

Der am Anker drehbar gelagerte Mittelbereich des Uebersetzungshebels ist vorteilhafterweise in einem mit dem Kontaktträger mitbeweglichen Führungs- und Anschlagsstück in Hubrichtung des Ankers geführt. Dadurch, dass der Mittelbereich des Uebersetzungshebels nicht im Gehäuse, sondern in einem mit dem Kontaktträger mitbeweglichen Führungs- und Anschlagsstück geführt ist, sind zwischen dem Kontaktträger und dem Gehäuse grössere, eine weniger aufwendige Montage erfordernde Toleranzen zulässig. Das Führungs- und Anschlagsstück kann aus einem mit einem Führungs- und Anschlagsschlitz versehenen, am Kontaktträger mittels Schnappverbindung befestigten Winkelstück bestehen. Das dem Kontaktträger abgekehrte Ende des Führungs- und Anschlagsschlitzes dient für den Anker als Anschlag und verhindert, dass der Anker bei der Montage oder Demontage aus dem Kontaktträger herausfällt. Ein mittels Schnappverbindung befestigbares Winkelstück ermöglicht eine einfache automatische Montage.The central region of the transmission lever, which is rotatably mounted on the armature, is advantageously guided in a guide and stop piece which is movable with the contact carrier in the stroke direction of the armature. Because the central region of the transmission lever is not guided in the housing, but rather in a guide and stop piece that is movable with the contact carrier, larger tolerances are required between the contact carrier and the housing, which require less complicated assembly. The guide and stop piece can consist of an angled piece provided with a guide and stop slot and fastened to the contact carrier by means of a snap connection. The end of the guide and stop slot facing away from the contact carrier serves as a stop for the anchor and prevents the anchor from falling out of the contact carrier during assembly or disassembly. An angle piece that can be fastened by means of a snap connection enables simple automatic assembly.

Der Uebersetzungshebel kann mindestens am einen Ende mit einem gerundeten, auf seiner Auflagefläche schwenkbaren und verschiebbaren Schuh versehen sein. Nachdem der Uebersetzungshebel mit seinen beiden Enden nur schwenkbar und verschiebbar abgestützt werden muss, ist es vorteilhaft diese verschiebbare und schwenkbare Abstützung mit einem Schuh zu lösen. Der Schuh besteht dabei vorteilhafterweise aus Kunststoff, wobei der Kunststoff auf der Abstützfläche gute Gleiteigenschaften aufweist. Der Schuh kann auf dem Uebersetzungshebel mittels Schnappverbindung befestigt sein, wodurch die Montage des Schuhs einfach erfolgen kann.The translation lever can be provided at least at one end with a rounded shoe which can be pivoted and displaced on its bearing surface. Since the translation lever with its two ends only has to be pivotably and displaceably supported, it is advantageous to release this displaceable and pivotable support with a shoe. The shoe is advantageously made of plastic, the plastic having good sliding properties on the support surface. The shoe can be fastened to the transmission lever by means of a snap connection, as a result of which the shoe can be easily assembled.

An zwei einander abgekehrten Seiten des Ankers ist vorteilhafterweise je ein Uebersetzungshebel angeordnet, wobei der Anker im Kontaktträger verschiebbar geführt ist. Diese platzsparende Anordnung verhindert ein Verklemmen des Ankers und des Kontaktträgers bei den Hubbewegungen. Die beiden Uebersetzungshebel greifen dabei mit Vorteil an zwei diagonal liegenden Stellen des Kontaktträgers an. Diese Massnahme dient wiederum zur Verhinderung eines Klemmens des Kontaktträgers während den Schaltbewegungen.A translation lever is advantageously arranged on each of the two sides of the armature facing away from one another, the armature being displaceably guided in the contact carrier. This space-saving arrangement prevents the armature and the contact carrier from jamming during the lifting movements. The two translation levers advantageously engage at two diagonally located points on the contact carrier. This measure in turn serves to prevent the contact carrier from jamming during the switching movements.

Fig.1 zeigt den Aufriss eines elektromagnetischen Schaltgerätes, das in diesem Beispiel als Schütz genannt wird, in schematischer Darstellung teilweise im Schnitt. Im Gehäuse 1 sind feste, in Fig.2 auch gut sichtbare Kontaktstücke 2 befestigt. An einem im Gehäuse 1 verschiebbar geführten Kontaktträger 3 sind mit den festen Kontaktstücken 2 in und ausser Eingriff bringbare, bewegliche Kontaktstücke 4 angebracht. Der Kontaktträger 3 erstreckt sich auf die untere Hälfte des Gehäuses 1, wo ein Schaltmagnet mit einem ortsfest gelagerten, eine Erregerwicklung 5 tragenden Kern 6 und mit einem Anker 7 untergebracht ist. Der Anker 7 ist im Kontaktträger 3 mit einem Bolzen 8 in einem Schlitz 9 verschiebbar geführt, wie dies in Fig.2 ersichtlich ist. Zwischen dem Anker 7 und dem Kontaktträger 3 sind zwei Federn 10 eingesetzt, die den Anker 7 vom Kontaktträger 3 in Hubrichtung des Ankers 7 wegdrücken.1 shows the elevation of an electromagnetic switching device, which is called a contactor in this example, in a schematic representation, partly in section. Fixed contact pieces 2, which are also clearly visible in FIG. 2, are fastened in the housing 1. Movable contact pieces 4, which can be brought into and out of engagement with the fixed contact pieces 2, are attached to a contact carrier 3 which is displaceably guided in the housing 1. The contact carrier 3 extends to the lower half of the housing 1, where a switching magnet with a stationary core 6 carrying an excitation winding 5 and an armature 7 is accommodated. The armature 7 is slidably guided in the contact carrier 3 with a bolt 8 in a slot 9, as can be seen in FIG. Between the armature 7 and the contact carrier 3, two springs 10 are inserted, which push the armature 7 away from the contact carrier 3 in the stroke direction of the armature 7.

Um einen Schaltmagneten mit einem im Verhältnis zum Schaltweg der beweglichen Kontaktstücke 4 kürzeren Hub verwenden zu können, ist zwischen dem Anker 7 und dem Kontaktträger 3 ein Uebersetzungshebel 11 vorgesehen. Der Uebersetzungshebel 11 liegt mit seinem einen Ende 12 am Gehäuse 1 und mit seinem anderen Ende 13 am Kontaktträger 3 auf. Sowohl am Gehäuse 1, als auch am Kontaktträger 3 sind Auflageflächen für die auf diesen Auflageflächen bei Schaltbewegungen sich schwenkenden und verschiebenden Enden 12, 13 des Uebersetzungshebels 11 ausgebildet. Die Auflageflächen bestehen aus Kunststoff, können aber auch aus einem geeigneten Metall hergestellt sein. Der Uebersetzungshebel 11 ist mit seinem Mittelbereich auf einem am Anker 7 angebrachten Bolzen 14 drehbar gelagert. Die Uebersetzung zwischen dem Schaltweg des Kontaktträgers 3 und dem Hub des Ankers 7 ist durch das Verhältnis der Hebelarme gegeben. Als Hebelarme müssen dabei einerseits die Distanz zwischen den Auflagestellen der beiden Enden 12, 13 des Uebersetzungshebels 11 und anderseits die Distanz zwischen dem Bolzen 14 am Anker 7 und der orstsfesten Auflagestelle des Endes 12 des Uebersetzungshebels 11 berücksichtigt werden. Beim Anziehen des Schaltmagneten nimmt der Anker 7 über den Bolzen 14 den Mittelbereich des mit seinem einen Ende 12 orstsfest aufliegenden Uebersetzungshebels 11 mit. Das andere Ende 13 des Uebersetzungshebels 11 drückt den Kontaktträger 3 mit den beweglichen Kontaktstücken 4 in die Einschaltstellung. Die zwischen dem Anker 7 und dem Kontaktträger 3 liegenden Feder 10 und auch die Rückstellfeder 15 des Kontaktträgers 3 werden dabei zusammengedrückt. Nach Unterbrechung der Speisespannung an der Erregerwicklung 5 des Schaltmagneten werden der Kontaktträger 3 und die daran angebrachten beweglichen Kontaktstücke 4 durch die Rückstellfeder 15 ungehindert in die ausgeschaltete Stellung gebracht. Die Federn 10 stossen dabei den Anker 7 vom Kontaktträger 3 weg, so dass die beiden Enden 12, 13 des am Anker 7 gelagerten Uebersetzungshebels 11 mit ihren Auflageflächen sowohl am Kontaktträger 3 als auch am Gehäuse 1 ständig in Berührung bleiben und der Anker 7 seine vorgesehene Lage im Kontaktträger 3 annimmt. Der durch die Rückstellfeder 15 belastete Kontaktträger 3 stützt sich in der Ausschaltstellung des Schützes an einem am Gehäuse 1 vorhandenen Anschlag.In order to be able to use a switching magnet with a shorter stroke in relation to the switching path of the movable contact pieces 4, a transmission lever 11 is provided between the armature 7 and the contact carrier 3. The translation lever 11 rests with its one end 12 on the housing 1 and with its other end 13 on the contact carrier 3. Both on the housing 1 and on the contact carrier 3, support surfaces are formed for the ends 12, 13 of the transmission lever 11 which pivot and shift on these support surfaces during switching movements. The contact surfaces are made of plastic, but can also be made of a suitable metal. The transmission lever 11 is rotatably supported with its central region on a bolt 14 attached to the armature 7. The translation between the switching path of the contact carrier 3 and the stroke of the armature 7 is given by the ratio of the lever arms. As lever arms, the distance between the support points of the two ends 12, 13 of the transmission lever 11 and, on the other hand, the distance between the bolt 14 on the armature 7 and the fixed support point of the end 12 of the transmission lever 11 must be taken into account. When the switching magnet is tightened, the armature 7 takes along the central region of the transmission lever 11, which is fixed at one end 12, via the bolt 14. The other end 13 of the translation lever 11 presses the contact carrier 3 with the movable contact pieces 4 into the switched-on position. The spring 10 lying between the armature 7 and the contact carrier 3 and also the return spring 15 of the contact carrier 3 are pressed together. After interrupting the Power supply to the excitation winding 5 of the switching magnet, the contact carrier 3 and the attached movable contact pieces 4 are brought unhindered into the switched-off position by the return spring 15. The springs 10 push the armature 7 away from the contact carrier 3, so that the two ends 12, 13 of the translation lever 11 mounted on the armature 7 constantly remain in contact with their contact surfaces on both the contact carrier 3 and the housing 1 and the armature 7 its intended Position in the contact carrier 3 assumes. The contact carrier 3, which is loaded by the return spring 15, is supported in the switched-off position of the contactor by an abutment on the housing 1.

Um den Bolzen 14 und somit auch den daran gelagerten Uebersetzungshebel 11 am Kontaktträger 3 führen zu können und um zu verhindern, dass bei der Montage oder Demontage der Anker 7 durch die Feder 10 aus dem Kontaktträger 3 herausgestossen wird, sind am Kontaktträger 3 beidseitig angebrachte Führungs- und Anschlagsstücke 16 vorgesehen. Jeder am Anker 7 befestigte Bolzen 14 ist in einem im Führungs- und Anschlagsstück 16 angebrachten, geschlossenenen Führungs- und Anschlagsschlitz geführt. Das untere Ende des Führungs- und Anschlagsschlitzes dient als Anschlag für den Bolzen 14 und somit auch für den ihn tragenden Anker 7. In den Figuren 3 und 4 sind der Aufriss bzw. der Seitenriss des aus einem Winkelstück bestehenden Führungs- und Anschlagsstückes 16 dargestellt. Dieses aus Kunststoff hergestellte Winkelstück ist an seinem einen Ende mit einem gabelförmigen Teil versehen, der durch Schnappverbindung in einer U-förmigen Nut am Kontaktträger 3 befestigt wird. Diese Befestigungsart ist besonders geeignet für eine automatische Montage.In order to be able to guide the bolt 14 and thus also the transmission lever 11 mounted thereon on the contact carrier 3 and to prevent the armature 7 from being pushed out of the contact carrier 3 by the spring 10 during assembly or disassembly, guides are attached to the contact carrier 3 on both sides - And stop pieces 16 provided. Each bolt 14 fastened to the armature 7 is guided in a closed guide and stop slot provided in the guide and stop piece 16. The lower end of the guide and stop slot serves as a stop for the bolt 14 and thus also for the anchor 7 carrying it. FIGS. 3 and 4 show the elevation or the side view of the guide and stop piece 16 consisting of an angle piece. This plastic angle piece is provided at one end with a fork-shaped part which is fastened by snap connection in a U-shaped groove on the contact carrier 3. This type of attachment is particularly suitable for automatic assembly.

Damit die Enden 12, 13 des Uebersetzungshebels 11 an den Auflagestellen sowohl am Gehäuse 1 als auch am Kontaktträger 3 gut schwenkbar und verschiebbar aufliegen können, sind an den beiden Enden 12, 13 des Uebersetzungshebels 11 aus Kunststoff bestehende Schuhe 17 angebracht. In den Figuren 5 und 6 sind der Aufriss bzw. der Seitenriss eines Schuhs 17 dargestellt. Der Schuh 17 ist durch Schnappverbindung am Ende 12, 13 des flachen Uebersetzungshebels 11 befestigt. Zu diesem Zweck weist der Schuh 17 zwei spreizbare, mit Haken abgeschlossene, in Fig.6 ersichtliche Seitenteile auf.So that the ends 12, 13 of the translation lever 11 can rest on the support points both on the housing 1 and on the contact carrier 3 such that they can be pivoted and slid well, shoes 17 made of plastic are attached to the two ends 12, 13 of the translation lever 11. FIGS. 5 and 6 show the elevation or the side elevation of a shoe 17. The shoe 17 is fastened by a snap connection to the end 12, 13 of the flat transmission lever 11. For this purpose, the shoe 17 has two expandable side parts which are closed off with hooks and can be seen in FIG.

Fig.7 zeigt den eingebauten Kontaktträger 3 ohne die beweglichen Kontaktstücke von oben her gesehen, wobei die oberen, den Kontaktträger 3 verdeckenden Teile des Schützes weggelassen sind. Man erkennt die an beiden einander abgekehrten Seiten des Kontaktträgers 3 liegenden Uebersetzungshebel 11 und die beiden am Kontaktträger 3 durch Schnappbefestigung angebrachten Führungs- und Anschlagsstücke 16. Die beiden Uebersetzungshebel 11 greifen mit ihren einen Enden 13 an zwei diagonal liegenden Stellen 18, 19 am Kontaktträger 3 an. Durch diese Anordnung kann ein Verklemmen des Kontaktträgers 3 im Gehäuse 1 verhindert werden. Die anderen Enden 12 der beiden Uebersetzungshebel 11 liegen dementsprechend auch an zwei diagonal angeordneten Auflagestellen des Gehäuses 1 auf.7 shows the built-in contact carrier 3 without the movable contact pieces, seen from above, the upper ones hiding the contact carrier 3 Parts of the contactor are omitted. One recognizes the translation levers 11 lying on both sides of the contact carrier 3 facing away from each other and the two guide and stop pieces 16 attached to the contact carrier 3 by snap fastening. The two translation levers 11 engage with their one ends 13 at two diagonally lying points 18, 19 on the contact carrier 3 at. This arrangement prevents the contact carrier 3 from jamming in the housing 1. The other ends 12 of the two transmission levers 11 are accordingly also on two diagonally arranged support points of the housing 1.

In Fig.8 ist der Kontaktträger 3 allein ohne bewegliche Kontaktstücke von oben her gesehen dargestellt. In dieser Figur 8 erkennt man deutlich die beiden diagonal liegenden Stellen 18, 19 des Kontaktträgers 3, die für die Enden 12, 13 der Uebersetzungshebel 11 als Auflageflächen dienen. Der Kontaktträger 3 ist im Gehäuse 1 durch die vorstehenden Teile 20 geführt.In Figure 8, the contact carrier 3 is shown alone without moving contact pieces seen from above. In this figure 8 one can clearly see the two diagonally lying points 18, 19 of the contact carrier 3, which serve as support surfaces for the ends 12, 13 of the transmission lever 11. The contact carrier 3 is guided in the housing 1 through the projecting parts 20.
