Abstract

A single-poled circuit breaker has a housing (1, 2) which there are a fixed (14) and a movable contact (15) connected to terminals (10, 11). The movable contact (14) is fitted on a switching bridge (4) arranged to pivot in the housing (1, 2) and connected to the switch button (3) via a lever (6). The switching bridge (4) is spring-loaded (7) in the closed position. When the switch button (3) is actuated, one end (17) of the lever (6) slides along a control slide (19) on the button (3) having two end stops (20, 21) and a supporting surface (23) between them, on which the lever (6) is temporarily supported during switch-on. The control slide (19) with the supporting surface (23) makes it possible to close the contacts (14, 15) rapidly but not so quickly that the movable contact (15) "vibrates" on the fixed contact (15), thus preventing the contacts (14, 15) from fusing together.

Description

Die Erfindung betrifft einen einpoligen Ausschalter mit einem Gehäuse, in dem ein ortsfester und ein beweglicher Kontakt angeordnet sind, die mit Anschlußklemmen verbunden sind, wobei der bewegliche Kontakt an einer beweglich im Gehäuse gelagerten Schaltbrücke angeordnet ist, die mit einem Schaltknopf über einen Zwischenhebel verbunden ist, und wobei der Zwischenhebel beim Betätigen des Schaltknopfes mit einem Ende an einer Steuerkulisse mit zwei Endanschlägen am Schaltknopf entlanggleitet.The invention relates to a single-pole switch with a Housing in which a fixed and a movable contact are arranged, which are connected to terminals, wherein the movable contact on a movably mounted in the housing Switching bridge is arranged with a switch button is connected via an intermediate lever, and wherein the intermediate lever when pressing the switch button with one end a control link with two end stops on the switch button slides along.

Die Erfindung betrifft weiters einen einpoligen Ausschalter mit einem Gehäuse, in dem ein ortsfester und ein beweglicher Kontakt angeordnet sind, die mit Anschlußklemmen verbunden sind, wobei der bewegliche Kontakt an einer beweglich im Gehäuse gelagerten Schaltbrücke angeordnet ist, die mit einem Schaltknopf über einen Zwischenhebel verbunden ist, und wobei der Zwischenhebel beim Betätigen des Schaltknopfes mit einem Ende an einer Steuerkulisse mit zwei Endanschlägen an der Schaltbrücke entlanggleitet.The invention further relates to a single-pole switch with a housing in which a stationary and a movable Contact are arranged, which are connected to terminals are, the movable contact on a movable in the housing stored switching bridge is arranged with a Switch button is connected via an intermediate lever, and wherein the intermediate lever when pressing the switch button with a End on a control link with two end stops on the Switch bridge slides along.

Bei derartigen Schaltern stellt sich insbesondere bei höheren zu schaltenden Leistungen, beispielsweise 80A oder darüber, das Problem, daß kurz vor dem Schließen der Kontakte ein Lichtbogen zu brennen beginnt, der Material an den Kontakten zum Schmelzen bringt und dadurch die Kontakte nach dem Schließen und dem Abkühlen miteinander verschweißen.Such switches are found, in particular, at higher ones powers to be switched, for example 80A or above, the problem that just before closing the contacts Arc begins to burn, the material on the contacts melts and thereby the contacts after closing and weld together after cooling.

Schalter, bei denen ein Zwischenhebel zwischen einem Schaltknopf und einer Schaltbrücke in einer Steuerkulisse am Schaltknopf oder an der Schaltbrücke entlanggleitet, sind aus der GB 1 552 180 A und der GB 2 157 499 A bekannt.Switches with an intermediate lever between a switch button and a switching bridge in a control link on the switching button or slides along the switching bridge are from the GB 1 552 180 A and GB 2 157 499 A are known.

Die FR-A-2552930 zeigt einen Schaltmechanismus, bei dem ein Klinkenhebel mit einem Steuerhebel zusammenwirkt, wobei der Steuerhebel über eine Kulisse mit Rastnase durch einen Stift an dem Kontakthebel diesen bewegt. Ab einer bestimmten Drehstellung der Kulisse und damit der Rastnase erfolgt eine sprungartige Bewegung des Stiftes und damit des Kontakthebels. The FR-A-2552930 shows a switching mechanism in which a Jack lever cooperates with a control lever, the Control lever over a backdrop with a latch by a pin moved on the contact lever. From a certain turning position the backdrop and thus the latch is one abrupt movement of the pin and thus the contact lever.

Aufgabe der Erfindung ist es, einen Ausschalter zur Verfügung zu stellen, bei dem das beschriebene Verschweißen der Kontakte soweit wie möglich verhindert wird.The object of the invention is to provide a switch to provide, in which the described welding of the contacts is prevented as far as possible.

Gelöst wird diese Aufgabe bei den gattungsgemäßen Ausschaltern dadurch, daß die Schaltbrücke durch die Kraft einer Feder in die Schließstellung belastet wird, und daß das der Steuerkulisse zugeordnete Ende des Zwischenhebels beim Einschalten des Ausschalters nach dem Überschreiten eines Totpunktes durch die Kraft der Feder von einer Stellung an der Steuerkulisse in eine andere Stellung springt.This task is solved with the generic switches in that the switching bridge by the force of a spring in the closed position is loaded, and that the control link assigned end of the intermediate lever when switching on the Switch off after a dead center is exceeded by the Force of the spring from a position on the control link in another position jumps.

Die Erfindung macht sich den Umstand zu Nutze, daß das Aufschmelzen der Kontakte und anschließende Verschweißen derselben umso geringer ist, je kürzer der Einschaltvorgang dauert, d.h. je schneller die Kontakte schließen. Durch die Steuerkulisse, die entweder an der Schaltbrücke oder bevorzugt am Schaltknopf angeordnet ist, kann sich der Zwischenhebel beim Einschalten ab einem bestimmten Schaltweg frei entlang der Steuerkulisse entlangbewegen, ohne an die Bewegung des Schaltknopfes gebunden zu sein, wodurch die Kontakte ungehindert sehr rasch schließen können.The invention takes advantage of the fact that the melting the contacts and then welding them together the shorter the switch-on process lasts, i.e. the faster the contacts close. Through the control backdrop, either on the switching bridge or preferably on Switch button is arranged, the intermediate lever at Switching on freely after a certain switching path along the Move the control link along without moving the shift button to be bound, which makes the contacts unimpeded can close very quickly.

Ein Problem, das sich dabei jedoch stellen kann ist, daß der bewegliche Kontakt an der Schaltbrücke so schnell auf den ortsfesten Kontakt auftrifft, daß er von diesem wieder zurückspringt und erst nach mehrmaligen Auftreffen und Zurückspringen fest am ortsfesten Kontakt anliegt. Da auch dabei ein Lichtbogen gezündet wird, der zum ungewünschten Verschweißen führen kann, ist in einer Weiterbildung der Erfindung vorgesehen, daß die Steuerkulisse zwei Endanschläge aufweist und daß zwischen den Endanschlägen eine Anlagefläche angeordnet ist, an der sich der Zwischenhebel während der Einschaltbewegung vorübergehend abstützt.One problem that can arise, however, is that the moving contact on the switching bridge so quickly on the stationary contact hits that he jumps back from this and only after multiple hits and jumps back is firmly attached to the stationary contact. Because there too Arc is ignited, which leads to unwanted welding a further development of the invention provides that the control link has two end stops and that a contact surface is arranged between the end stops, on the intermediate lever during the switch-on movement temporarily supported.

An dieser Anlagefläche liegt der Zwischenhebel beim Schließen des Schalters an, bis die Kontakte fast geschlossen sind und gleitet dann von dieser ab und an der Steuerkulisse frei weiter, bis die Kontakte geschlossen sind. Durch den sehr kurzen Abstand zwischen den beiden Kontakten im Zeitpunkt des Abgleitens des Zwischenhebels von der Anlagefläche ist die Auftreffgeschwindigkeit des beweglichen Kontaktes am festen Kontakt zwar so gering, daß das beschriebene mehrfache Abheben des beweglichen Kontaktes vom ortsfesten Kontakt so gut wie vollständig vermieden werden kann, aber doch so groß, daß es zu keinem Verschweißen der Kontakte kommen kann. The intermediate lever is located on this contact surface when closing the switch until the contacts are almost closed and then glides off and on to the control link, until the contacts are closed. Because of the very short Distance between the two contacts at the time of sliding of the intermediate lever from the contact surface is the impact speed of moving contact on fixed contact so small that the multiple lifting of the described movable contact from the stationary contact almost completely can be avoided, but still so big that it is too no welding of the contacts can occur.

Um die Bewegung des Zwischenhebels an der Steuerkulisse, insbesondere das Abgleiten des Zwischenhebels von der Anlagefläche genau steuern zu können, ist in einer Weiterbildung der Erfindung vorgesehen, daß am Schaltknopf ein Anschlag angeordnet ist, der den Zwischenhebel während der Einschaltbewegung in die EIN-Stellng drückt.To the movement of the intermediate lever on the control link, in particular the sliding of the intermediate lever from the contact surface To be able to control precisely is in a further training Invention provided that a stop arranged on the switch button is the intermediate lever during the switch-on movement in the ON position.

Durch den Anschlag am Schaltknopf wird der Zwischenhebel an der Steuerkulisse entlang bewegt, insbesondere von der Anlagefläche weggeschoben, wenn der Abstand zwischen den beiden Kontakten einen vorgegebenen Wert erreicht hat, so daß der Zeitpunkt, wann der Zwischenhebel von der Anlagefläche abgleitet, d.h. bei welchem Abstand zwischen den beiden Kontakten dies erfolgt, nicht von Fertigungsungenauigkeiten oder Verchleißerscheinungen an der Anlagefläche beeiflußt wird.The intermediate lever is activated by the stop on the switch button moves along the control link, in particular from the contact surface pushed away when the distance between the two Contacts has reached a predetermined value so that the When the intermediate lever slides off the contact surface i.e. at what distance between the two contacts this is not due to manufacturing inaccuracies or signs of wear is influenced on the contact surface.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den übrigen Unteransprüchen und der nachfolgenden Beschreibung eines Ausführungsbeispieles der Erfindung.Further features and advantages of the invention result from the remaining subclaims and the description below an embodiment of the invention.

    • Der erfindungsgemäße Ausschalter besteht im wesentlichen aus einem Gehäuse mit einer Unterschale 1 und einer Oberschale 2, in denen Anschlußklemmen 10, 11 an sich bekannter Art aufgenommen sind. Die Anschlußklemme 10 ist über ein Rundseil 8 mit einer Schaltbrücke 4 verbunden, die an einem Ende an einem Bolzen 13 im Gehäuse 1, 2 gelagert ist. Am anderen Ende der Schaltbrücke 4 ist ein beweglicher Kontakt 14 angeordnet, der mit einem ortsfesten Kontakt 15 zusammenwirkt um (im eingeschalteten Zustand des Ausschalters) über ein Leiterblech 12, an dem der Kontakt 15 und die zweite Anschlußklemme 11 befestigt sind, eine elektrische Verbindung zwischen den Klemmen 10 und 11 herzustellen.The switch according to the invention consists essentially of a housing with a lower shell 1 and an upper shell 2, in which terminals 10, 11 are recorded in a manner known per se are. The connecting terminal 10 is connected via a round cable 8 a switching bridge 4 connected at one end to a Bolt 13 is mounted in the housing 1, 2. At the other end of the Switch bridge 4, a movable contact 14 is arranged, the interacts with a fixed contact 15 (in the on State of the switch) via a printed circuit board 12, to which the contact 15 and the second terminal 11 are attached are an electrical connection between the terminals 10 and 11 to manufacture.

    Etwa im Mittelbereich der Schaltbrücke 4 ist ein abgewinkeltes Ende 16 eines im wesentlichen U-förmigen Zwischenhebels 6 gelagert. Der Zwischenhebel 6 kann beispielsweise ein Drahtbügel sein. Das andere abgewinkelte Ende 17 des Zwischenhebels 6 ist in einer Ausnehmung bzw. Nut 18 in einem Schaltknopf 3 aufgenommen, der drehbar im Gehäuse 1, 2 gelagert ist.Around the middle of the switching bridge 4 is an angled one End 16 of a substantially U-shaped intermediate lever 6 stored. The intermediate lever 6 can for example be a wire bracket be. The other angled end 17 of the intermediate lever 6 is in a recess or groove 18 in a switch button 3 added, which is rotatably mounted in the housing 1, 2.

    Die Ausnehmung 18 wird auf der der Schaltbrücke 4 abgewandten Seite von einer Steuerkulisse 19 begrenzt (Fig. 5), an der sich der Zwischenhebel 6 mit seinem abgewinktelten Ende 17 durch die Kraft einer Feder 7 belastet abstützt und an dieser entlanggleitet. Die Feder 7 ist eine Druckfeder, die sich einerseits an der Schaltbrücke 4 und anderseits am Gehäuse 1, 2 abstützt.The recess 18 is facing away from the switching bridge 4 Side limited by a control link 19 (Fig. 5) on the the intermediate lever 6 with its angled end 17th supported by the force of a spring 7 and supported on this slides along. The spring 7 is a compression spring on the one hand on the switching bridge 4 and on the other hand on the housing 1, 2 supports.

    Die Steuerkulisse 19 bzw. die Ausnehmung 18 wird von Endanschlägen 20, 21 begrenzt. Im Mittelbereich der Steuerkulisse 19 etwas zum Endanschlag 20 hin versetzt ist eine Erhebung 22 angeordnet, welche eine Anlagefläche 23 für den Zwischenhebel 6 bildet.The control link 19 or the recess 18 is made of end stops 20, 21 limited. In the middle of the control link 19 is slightly offset towards the end stop 20 is an elevation 22 arranged, which has a contact surface 23 for the intermediate lever 6 forms.

    Wird der erfindungsgemäße Ausschalter ausgehend von der in Fig. 3 dargestellten AUS-Stellung eingeschaltet, indem der Schaltknopf 3 gegen den Uhrzeigersinn betätigt wird, gleitet der Zwischenhebel 6, nachdem der Totpunkt, bei dem die Drehachse des Schaltknopfes 3 etwa in der Verlängerung des Zwischenhebebels 6 liegt, überwunden wurde, mit seinem Ende 17 zunächst vom Endanschlag 21 weg in die in Fig. 4 dargestellte Stellung, in der das Ende 17 an der Anlagefläche 23 anliegt, wodurch die "unkontrollierte" Schließbewegung der Schaltbrücke 4 auf den ortsfesten Kontakt 15 hin vorerst gehemmt wird. In dieser Stellung sind die beiden Kontakte 14 und 15 beispielsweise nur etwa 1 mm voneinander entfernt. If the switch according to the invention is based on the in Fig. 3 shown OFF position turned on by the Switch button 3 is operated counterclockwise, slides the intermediate lever 6 after the dead center at which the axis of rotation the switch button 3 approximately in the extension of the intermediate lever 6 lies, was overcome, with its end 17 first away from the end stop 21 into that shown in FIG. 4 Position in which the end 17 lies against the contact surface 23 causing the "uncontrolled" closing movement of the switching bridge 4 is initially inhibited on the fixed contact 15. In this position, the two contacts 14 and 15 are for example only about 1 mm apart.

    Wird der Schaltknopf 3 nun weiter gegen den Uhrzeigersinn verdreht, dann gleitet das Ende 17 des Zwischenhebels 6 von der Anlagefläche 23 an der Erhebung 22 ab und die Kontakte 14 und 15 werden schlagartig geschlossen. Da die Bewegung der Schaltbrücke jedoch zwischendurch durch das Auflaufen des Zwischenhebels 6 an der Anlagefläche 23 kurzfristig gehemmt wurde, ist die Geschwindigkeit bzw. Bewegungsenergie der Schaltbrücke 4 nicht mehr so groß, daß es zu dem unerwünschten Abheben bzw. Zurückspringen des beweglichen Kontaktes 14 vom ortsfesten Kontakt 15 kommt, wodurch auch die Gefahr des Verschweißens der Konatkte 14, 15 verringert wird. Andererseits ist es jedoch so, daß nach dem Abgleiten des Zwischenhebels 16 von der Anlagefläche 23 ein ungehemmtes und relativ rasches Schließen der Kontakte 14, 15 möglich ist, was ebenfalls für ein Schließen der Kontakte 14, 15 ohne Verschweißen erforderlich ist.If the switch button 3 is now turned further counterclockwise, then the end 17 of the intermediate lever 6 slides from the Contact surface 23 on the elevation 22 and the contacts 14 and 15 are closed suddenly. Because the movement of the switching bridge however, in the meantime through the run-up of the intermediate lever 6 was temporarily inhibited on the contact surface 23 the speed or kinetic energy of the switching bridge 4 not so big anymore that it leads to the unwanted lifting or Spring back of the movable contact 14 from the stationary Contact 15 comes, which also increases the risk of welding the contacts 14, 15 is reduced. On the other hand, it is so that after the sliding of the intermediate lever 16 from the Contact surface 23 an uninhibited and relatively quick closing the contacts 14, 15 is possible, which is also a closing the contacts 14, 15 is required without welding.

    Um das Abgleiten des Endes 17 des Zwischenhebels 6 von der Anlagefläche 23 zu unterstützten und ein kontrolliertes Abgleiten zu ermöglichen, ist am Schaltknopf 3 weiters ein Anschlag 25 angeordnet, der in der in Fig. 4 dargestellten Stellung am Zwischenhebel 6 anliegt und diesen bei der weiteren Bewegung des Schaltknopfes 3 entgegen dem Uhrzeigersinn von der Anlagefläche 23 hinunterschiebt.To the sliding of the end 17 of the intermediate lever 6 from the contact surface 23 to support and controlled sliding To enable, there is also a stop on the button 3 25 arranged in the position shown in Fig. 4 on Intermediate lever 6 rests and this during further movement the switch button 3 counterclockwise from the contact surface 23 slides down.

    Zum Ausschalten des Schalters wird der Schaltknopf 3 zunächst im Uhrzeigersinn so weit gedreht, bis das Ende 17 des Zwischenhebels 6 am Endanschlag 20 anliegt. Durch weiteres Drehen des Schaltknopfes 3 wird dann der bewegliche Kontakt 14 vom ortsfesten Kontakt 15 abgehoben. Nachdem der Zwischenhebel 6 wieder den Totpunkt überwunden hat, springt er über die Erhebung 22 an der Steuerkulisse mit seinem Ende 17 nach links zum Endanschlag 21 und drückt den Schaltknopf 3 so weit im Uhrzeigersinn weiter, bis dieser an einer Anschlagfläche 26 am Gehäuse 1, 2 anliegt.To turn off the switch, the button 3 is first turned clockwise until the end 17 of the intermediate lever 6 abuts the end stop 20. By further turning of the button 3, the movable contact 14 is then Fixed contact 15 lifted off. After the intermediate lever 6 has overcome the dead center again, he jumps over the elevation 22 on the control link with its end 17 to the left End stop 21 and presses the button 3 clockwise so far continue until this on a stop surface 26 on the housing 1, 2 is present.

    Es versteht sich, daß im Rahmen der vorliegenden Erfindung Änderungen des in den Zeichnungen dargestellten Ausführungsbeispiel möglich sind. Beispielsweise können der Schaltknopf und die Schaltbrücke nicht drehbar sondern translatorisch verschiebbar im Gehäuse gelagert sein. Weiters kann die Steuerkulisse anstatt am Schaltknopf 3 an der Schaltbrücke 4 angeordnet sein. Weiters ist es möglich, daß, wenn dies auch nicht die bevorzugte Ausführungsform der Erfindung ist, an der Steuerkulisse keine Anlagefläche vorgesehen ist und die Bewegung des Zwischenhebels an der Steuerkulisse gegebenenfalls nur vom Anschlag 25 unterstützt wird.It is understood that within the scope of the present invention Changes to the embodiment shown in the drawings possible are. For example, the switch button and the switching bridge is not rotatable but translational be slidably mounted in the housing. Furthermore, the control backdrop arranged on the switching bridge 4 instead of the switch button 3 be. It is also possible that, if so is not the preferred embodiment of the invention in which Control link is not provided and the movement of the intermediate lever on the control link if necessary is only supported by the stop 25.

    Zusammenfassend kann ein Ausführungsbeispiel der Erfindung wie folgt dargestellt werden:In summary, an embodiment of the invention can be like are represented as follows:

    Ein einpoliger Ausschalter weist ein Gehäuse 1, 2 auf, in dem ein ortsfester 14 und ein beweglicher Kontakt 15 angeordnet sind, die mit Anschlußklemmen 10, 11 verbunden sind. Der bewegliche Kontakt 14 ist an einer schwenkbar im Gehäuse 1, 2 gelagerten Schaltbrücke 4 angeordnet, die über einen Zwischenhebel 6 mit dem Schaltknopf 3 verbunden ist. Die Schaltbrücke 4 wird durch die Kraft einer Feder 7 in die Schließstellung belastet. Der Zwischenhebel 6 gleitet beim Betätigen des Schaltknopfes 3 mit einem Ende 17 an einer Steuerkulisse 19 am Schaltknopf 3 entlang, die zwei Endanschläge 20, 21 und zwischen den Endanschlägen 20, 21 eine Anlagefläche 23 aufweist, an der sich der Zwischenhebel 6 während der Einschaltbewegung vorübergehend abstützt.A single-pole switch has a housing 1, 2 in which a stationary 14 and a movable contact 15 are arranged are connected to terminals 10, 11. The mobile Contact 14 is pivotable in the housing 1, 2 stored switching bridge 4 arranged via an intermediate lever 6 is connected to the switch button 3. The switching bridge 4 is in the closed position by the force of a spring 7 charged. The intermediate lever 6 slides when the Switch button 3 with one end 17 on a control link 19 on Switch button 3 along, the two end stops 20, 21 and between the end stops 20, 21 have a contact surface 23, on which the intermediate lever 6 during the switch-on movement temporarily supported.

    Durch die Steuerkulisse 19 mit der Anlagefläche 23 ist es möglich, daß die Kontakte 14, 15 zwar rasch schließen, aber nicht so schnell, das der bewegliche Kontakt 14 am ortsfesten Kontakt 15 "vibiriert", so daß es nicht zum Verschweißen der Kontakte 14, 15 kommt.The control link 19 with the contact surface 23 makes it possible to that the contacts 14, 15 close quickly, but not so quickly that the movable contact 14 at the fixed contact 15 "vibrates" so that it is not for welding the Contacts 14, 15 is coming.
