Description

Die Erfindung betrifft ein Getriebe zur einander entgegengesetzten Bewegung zweier Schaltkontakte eines Leistungsschalters.The invention relates to a transmission for opposing movement of two switching contacts of a circuit breaker.

Mit steigender Spannungsebene erhöhen sich die in einem Leistungsschalter erforderlichen relativen Kontaktgeschwindigkeiten der Schaltkontakte. Bei hohen Spannungsebenen wird die erforderliche relative Kontaktgeschwindigkeit daher oft durch eine einander entgegengesetzte Bewegung der Schaltkontakte realisiert. Dabei wird die Bewegung der Schaltkontakte beispielsweise durch ein Getriebe realisiert, wie z. B. aus der DE 197 38 697 C1 bekannt ist, durch das die Schaltkontakte gleichzeitig in einander entgegengesetzte Richtungen bewegt werden. Mit steigender Kontaktgeschwindigkeit wächst die Belastung der mechanischen Bauteile im Getriebe. Hohe Belastungen können Bauteile im Getriebe schädigen oder sogar zerstören und gefährden dadurch die Dauerschaltfestigkeit des Leistungsschalters.As the voltage level rises, the relative contact speeds of the switching contacts required in a circuit breaker increase. At high voltage levels, the required relative contact speed is therefore often achieved by moving the switching contacts in opposite directions. The movement of the switching contacts is realized, for example, by a transmission, such as. B. from the DE 197 38 697 C1 is known, through which the switching contacts are moved simultaneously in opposite directions. As the contact speed increases, so does the stress on the mechanical components in the transmission. High loads can damage or even destroy components in the gearbox and thereby endanger the continuous switching strength of the circuit breaker.

Der Erfindung liegt die Aufgabe zugrunde, ein insbesondere hinsichtlich der Belastung bei hohen Kontaktgeschwindigkeiten verbessertes Getriebe zur einander entgegengesetzten Bewegung zweier Schaltkontakte eines Leistungsschalters anzugeben.The invention is based on the object of specifying a transmission, which is improved in particular with regard to the load at high contact speeds, for the opposing movement of two switching contacts of a circuit breaker.

Die Aufgabe wird erfindungsgemäß durch ein Getriebegehäuse mit den Merkmalen des Anspruchs 1 und ein Getriebe mit den Merkmalen des Anspruchs 10 gelöst.The object is achieved according to the invention by a gear housing with the features of claim 1 and a gear with the features of claim 10.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the subclaims.

Ein erfindungsgemäßes Getriebegehäuse für ein Getriebe mit einem zweiseitigen Steuerhebel zur einander entgegengesetzten Bewegung zweier Schaltkontakte eines Leistungsschalters umfasst eine Gehäusekassette mit einem Gehäuseboden, eine Decckelplatte, eine Lagerachse zur um die Lagerachse drehbaren Lagerung des Steuerhebels und wenigstens ein Zapfenelement. Die Deckelplatte ist durch Schraubverbindungen lösbar mit der Gehäusekassette verbunden und liegt dem Gehäuseboden gegenüber. Die Lagerachse ist mit der Gehäusekassette und der Deckelplatte verbunden und erstreckt sich zwischen dem Gehäuseboden und der Deckelplatte. Jedes Zapfenelement verbindet formschlüssig die Gehäusekassette und die Deckelplatte.A transmission housing according to the invention for a transmission with a two-sided control lever for opposing movement of two switching contacts of a circuit breaker comprises a housing cassette with a housing base, a cover plate, a bearing axis for mounting the control lever so that it can rotate about the bearing axis and at least one pin element. The cover plate is detachably connected to the housing cassette by screw connections and lies opposite the housing base. The bearing axis is connected to the housing cassette and the cover plate and extends between the housing base and the cover plate. Each pin element positively connects the housing cassette and the cover plate.

Das Getriebegehäuse sieht also wenigstens ein Zapfenelement vor, das die Gehäusekassette und die Deckelplatte zusätzlich zu kraftschlüssigen Schraubverbindungen formschlüssig miteinander verbindet. Diese formschlüssige Verbindung nimmt Querkräfte auf, die in der Ebene der Deckelplatte über die Lagerachse bei Drehungen des Steuerhebels auf die Deckelplatte ausgeübt werden. Dadurch entlastet die durch das wenigstens eine Zapfenelement hergestellte formschlüssige Verbindung der Deckelplatte mit der Gehäusekassette die Schraubverbindungen. Ohne eine derartige Entlastung können hohe Querkräfte die Schraubenvorspannungen der Schraubverbindungen reduzieren und die Schraubverbindungen lockern, so dass sich die Deckelplatte relativ zu der Gehäusekassette verschieben kann. Dies destabilisiert auch die Lagerachse und kann zu deren Schädigung oder sogar Zerstörung führen, wodurch die Funktionsfähigkeit des Getriebes beeinträchtigt oder zerstört werden kann. Bei einem erfindungsgemäßen Getriebegehäuse werden also hohe Belastungen der Schraubverbindungen durch hohe Querkräfte bei großen Kontaktgeschwindigkeiten der Schaltkontakte vermieden, indem Querkräfte durch die formschlüssige Verbindung der Deckelplatte mit der Gehäusekassette mittels wenigstens eines Zapfenelements kompensiert werden.The gear housing therefore provides at least one pin element which connects the housing cassette and the cover plate to one another in a form-fitting manner in addition to non-positive screw connections. This form-fitting connection absorbs transverse forces that are exerted on the cover plate in the plane of the cover plate via the bearing axis when the control lever is rotated. As a result, the positive connection of the cover plate to the housing cassette produced by the at least one pin element relieves the screw connections. Without such relief, high transverse forces can reduce the screw prestresses of the screw connections and loosen the screw connections so that the cover plate can move relative to the housing cassette. This also destabilizes the bearing axis and can damage it or even destroy it, which can impair or destroy the functionality of the gear unit. In a transmission housing according to the invention, high loads on the screw connections due to high transverse forces at high contact speeds of the switching contacts are avoided by compensating for transverse forces through the positive connection of the cover plate to the housing cartridge by means of at least one pin element.

Eine Ausgestaltung der Erfindung sieht vor, dass jedes Zapfenelement parallel zu der Lagerachse verläuft. Diese Ausgestaltung der Erfindung ermöglicht eine besonders effiziente Aufnahme von Querkräften durch die Ausrichtung der Zapfenelemente parallel zu der Lagerachse, durch die Querkräfte übertragen werden.One embodiment of the invention provides that each pin element runs parallel to the bearing axis. This embodiment of the invention enables a particularly efficient absorption of transverse forces by aligning the pin elements parallel to the bearing axis, through which transverse forces are transmitted.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass wenigstens ein Zapfenelement einstückig mit der Gehäusekassette ausgebildet ist, und dass die Deckelplatte eine zu dem Zapfenelement korrespondierende Deckelaussparung aufweist, in die das Zapfenelement hineinragt. Diese Ausgestaltung der Erfindung ermöglicht eine besonders stabile formschlüssige Verbindung der Gehäusekassette und der Deckelplatte durch die Ausführung von Zapfenelementen als Teil der Gehäusekassette.Another embodiment of the invention provides that at least one pin element is formed in one piece with the housing cassette, and that the cover plate has a cover recess corresponding to the pin element, into which the pin element protrudes. This embodiment of the invention enables a particularly stable, form-fitting connection between the housing cassette and the cover plate through the implementation of pin elements as part of the housing cassette.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass wenigstens ein Zapfenelement einstückig mit der Deckelplatte ausgebildet ist, und dass die Gehäusekassette eine zu dem Zapfenelement korrespondierende Kassettenaussparung aufweist, in die das Zapfenelement hineinragt. Diese Ausgestaltung der Erfindung ermöglicht eine besonders stabile formschlüssige Verbindung der Gehäusekassette und der Deckelplatte durch die Ausführung von Zapfenelementen als Teil der Deckelplatte.Another embodiment of the invention provides that at least one pin element is formed in one piece with the cover plate, and that the housing cassette has a cassette recess corresponding to the pin element, into which the pin element protrudes. This embodiment of the invention enables a particularly stable, form-fitting connection of the housing cassette and the cover plate through the implementation of pin elements as part of the cover plate.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass wenigstens ein Zapfenelement als ein Stiftelement, beispielsweise als ein Spannstift, ausgebildet ist, das durch eine Deckelaussparung in der Deckelplatte in eine Kassettenaussparung in der Gehäusekassette geführt ist. Alternativ oder zusätzlich kann wenigstens ein Zapfenelement als eine Passschraube mit einem Außengewinde ausgebildet sein, die durch eine Deckelaussparung in der Deckelplatte geführt ist und in eine Kassettenaussparung in der Gehäusekassette mit einem zu dem Außengewinde der Passschraube korrespondierenden Innengewinde geschraubt ist. Diese Ausgestaltungen der Erfindung ermöglichen eine flexible, insbesondere bedarfsweise Anordnung von Zapfenelementen durch deren Ausführung als Stiftelemente oder/und Passschrauben. Eine Ausführung eines Zapfenelements als Spannstift oder als Passschraube ermöglicht dabei vorteilhaft eine einfache und zuverlässige Fixierung des Zapfenelements in der Gehäusekassette.Another embodiment of the invention provides that at least one pin element is designed as a pin element, for example as a dowel pin, which is guided through a cover recess in the cover plate into a cassette recess in the housing cassette. Alternatively or additionally, at least one pin element can be designed as a fitting screw with an external thread, which is guided through a cover recess in the cover plate and is screwed into a cassette recess in the housing cassette with an internal thread corresponding to the external thread of the fitting screw. These refinements of the invention enable a flexible, in particular if necessary, arrangement of pin elements by designing them as pin elements and / or fitting screws. An embodiment of a pin element as a dowel pin or as a fitting screw advantageously enables simple and reliable fixing of the pin element in the housing cassette.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Lagerachse einstückig mit der Gehäusekassette ausgebildet ist, und dass die Deckelplatte eine zu der Lagerachse korrespondierende Deckelaussparung aufweist, in die die Lagerachse hineinragt. Alternativ dazu kann die Lagerachse einstückig mit der Deckelplatte ausgebildet sein, und die Gehäusekassette kann eine zu Lagerachse korrespondierende Kassettenaussparung aufweisen, in die die Lagerachse hineinragt. Beide Ausgestaltungen der Erfindung ermöglichen eine besonders stabile Lagerung der Lagerachse als Teil der Gehäusekassette bzw. als Teil der Deckelplatte.Another embodiment of the invention provides that the bearing axis is formed in one piece with the housing cassette, and that the cover plate has a cover recess corresponding to the bearing axis into which the bearing axis protrudes. Alternatively, the bearing axis can be formed in one piece with the cover plate, and the housing cassette can have a cassette recess that corresponds to the bearing axis and into which the bearing axis protrudes. Both embodiments of the invention enable a particularly stable mounting of the bearing axis as part of the housing cassette or as part of the cover plate.

Ein erfindungsgemäßes Getriebe zur einander entgegengesetzten Bewegung zweier Schaltkontakte eines Leistungsschalters umfasst ein erfindungsgemäßes Getriebegehäuse und einen in dem Getriebegehäuse angeordneten zweiseitigen Steuerhebel. Eine erste Hebelseite des Steuerhebels ist mit einem ersten Schaltkontakt gekoppelt und die zweite Hebelseite ist mit dem zweiten Schaltkontakt gekoppelt. Der Steuerhebel weist eine Hebelaussparung auf, durch die die Lagerachse des Getriebegehäuses geführt ist, so dass der Steuerhebel um die Lagerachse drehbar gelagert ist. Die Vorteile des Getriebes ergeben sich aus den oben bereits genannten Vorteilen des Getriebegehäuses.A transmission according to the invention for opposing movement of two switching contacts of a circuit breaker comprises a transmission housing according to the invention and a two-sided control lever arranged in the transmission housing. A first lever side of the control lever is coupled to a first switch contact and the second lever side is coupled to the second switch contact. The control lever has a lever recess through which the bearing axis of the gear housing is guided, so that the control lever is rotatably mounted about the bearing axis. The advantages of the transmission result from the advantages of the transmission housing already mentioned above.

Die erste Hebelseite des Steuerhebels ist beispielsweise über eine in das Getriebegehäuse hineinragende Antriebsstange mit dem ersten Schaltkontakt verbunden. Dabei weist die erste Hebelseite beispielsweise wenigstens eine Koppelnase auf, und ein steuerhebelseitiger Endbereich der Antriebsstange weist für jede Koppelnase ein Langloch auf, in dem die Koppelnase geführt ist. Durch die Antriebsstange werden Drehungen des Steuerhebels auf den ersten Schaltkontakt übertragen. Die Kopplung des Steuerhebels und der Antriebsstange über wenigstens eine in einem Langloch der Antriebsstange geführte Koppelnase des Steuerhebels ermöglicht eine Übersetzung von Drehungen des Steuerhebels in Translationen der Antriebsstange.The first lever side of the control lever is connected to the first switching contact, for example, via a drive rod protruding into the gearbox housing. The first lever side has, for example, at least one coupling nose, and an end region of the drive rod on the control lever side has an elongated hole for each coupling nose, in which the coupling nose is guided. Rotations of the control lever are transmitted to the first switching contact through the drive rod. The coupling of the control lever and the drive rod via at least one coupling nose of the control lever guided in an elongated hole in the drive rod enables a translation of rotations of the control lever into translations of the drive rod.

Die zweite Hebelseite des Steuerhebels ist beispielsweise über einen Bolzen mit dem zweiten Schaltkontakt gekoppelt, wobei der Bolzen in einer in das Getriebegehäuse hineinragenden Führungsschiene geführt ist, in die die zweite Hebelseite hineinragt. Die Führungsschiene mit dem Bolzen ermöglicht die Übersetzung von translatorischen Bewegungen des zweiten Schaltkontakts über den Bolzen in Drehungen des Steuerhebels durch den Kontakt des Bolzens mit der in die Führungsschiene hineinragenden zweiten Hebelseite.The second lever side of the control lever is coupled to the second switching contact via a bolt, for example, the bolt being guided in a guide rail protruding into the transmission housing into which the second lever side protrudes. The guide rail with the bolt enables the translation of translational movements of the second switching contact via the bolt into rotations of the control lever through the contact of the bolt with the second lever side protruding into the guide rail.

The gear 3 has a gear housing 5 with a housing cassette 7 and a cover plate 9. Figure 1 shows the gear housing 5 with the Cover plate 9. Figure 2 shows the gear housing 5 without the cover plate 9.

Das Getriebe 3 ist zur einander entgegengesetzten Bewegung zweier Schaltkontakte des Leistungsschalters 1 ausgebildet. Die Schaltkontakte sind in einem ersten Gehäuseteil 11 des Leistungsschalters 1 angeordnet und in den Figuren 1 und 2 nicht sichtbar. Der erste Gehäuseteil 11 ist mit einem zweiten Gehäuseteil 13 des Leistungsschalters 1 über eine Flanschverbindung 15 verbunden. Die Flanschverbindung 15 wird von einem ersten Flansch 17 des ersten Gehäuseteils 11 und einem dazu korrespondierenden zweiten Flansch 19 des zweiten Gehäuseteils 13 gebildet. Zwei sich diametral gegenüber liegende Flanschbereiche des ersten Flansches 17 sind durch einen Mittelsteg 21 miteinander verbunden. Der zweite Gehäuseteil 13 ist aufgebrochen dargestellt, um das Getriebe 3 sichtbar zu machen.The gear 3 is designed to move two switching contacts of the circuit breaker 1 in opposite directions. The switching contacts are arranged in a first housing part 11 of the circuit breaker 1 and in the Figures 1 and 2 not visible. The first housing part 11 is connected to a second housing part 13 of the circuit breaker 1 via a flange connection 15. The flange connection 15 is formed by a first flange 17 of the first housing part 11 and a corresponding second flange 19 of the second housing part 13. Two diametrically opposite flange areas of the first flange 17 are connected to one another by a central web 21. The second housing part 13 is shown broken away in order to make the transmission 3 visible.

Eine Stirnseite 23 der Gehäusekassette 7 ist durch in den Figuren 1 und 2 nicht sichtbare Befestigungsschraubverbindungen an dem Mittelsteg 21 befestigt. Die Gehäusekassette 7 ragt von dem Mittelsteg 21 in das zweite Gehäuseteil 13 hinein und weist einen Gehäuseboden 25 auf, der senkrecht von dem Mittelsteg 21 absteht. Die Deckelplatte 9 des Getriebegehäuses 5 ist durch Schraubverbindungen 27 lösbar mit der Gehäusekassette 7 verbunden und liegt dem Gehäuseboden 25 gegenüber.An end face 23 of the housing cassette 7 is fastened to the central web 21 by fastening screw connections which are not visible in FIGS. 1 and 2. The housing cassette 7 protrudes from the central web 21 into the second housing part 13 and has a housing base 25 which protrudes perpendicularly from the central web 21. The cover plate 9 of the gear housing 5 is detachably connected to the housing cassette 7 by screw connections 27 and lies opposite the housing base 25.

Um die Schaltkontakte zueinander entgegengesetzt zu bewegen, weist das Getriebe 3 einen in dem Getriebegehäuse 5 angeordneten zweiseitigen Steuerhebel 29 auf. Eine erste Hebelseite 31 des Steuerhebels 29 ist mit einem ersten Schaltkontakt gekoppelt. Eine der ersten Hebelseite 31 gegenüber liegende zweite Hebelseite 33 ist mit dem zweiten Schaltkontakt gekoppelt. Der Steuerhebel 29 weist eine Hebelaussparung 35 auf, durch die eine Lagerachse 37 des Getriebegehäuses 5 geführt ist, so dass der Steuerhebel 29 um die Lagerachse 37 drehbar gelagert ist.In order to move the switching contacts in opposite directions to one another, the transmission 3 has a two-sided control lever 29 arranged in the transmission housing 5. A first lever side 31 of the control lever 29 is coupled to a first switching contact. A second lever side 33 opposite the first lever side 31 is coupled to the second switching contact. The control lever 29 has a lever recess 35 through which a bearing axis 37 of the gear housing 5 is guided, so that the control lever 29 is rotatably mounted about the bearing axis 37.

Die Lagerachse 37 ist Teil der Gehäusekassette 7, d. h. einstückig mit der Gehäusekassette 7 ausgebildet. Die Deckelplatte 9 weist eine zu der Lagerachse 37 korrespondierende erste Deckelaussparung 39 auf, in die die Lagerachse 37 hineinragt. Die erste Deckelaussparung 39 ist als ein Durchloch in der Deckelplatte 9 ausgebildet.The bearing axis 37 is part of the housing cartridge 7, i. H. formed in one piece with the housing cassette 7. The cover plate 9 has a first cover recess 39 which corresponds to the bearing axis 37 and into which the bearing axis 37 protrudes. The first cover recess 39 is designed as a through hole in the cover plate 9.

Das Getriebegehäuse 5 weist ferner zwei Zapfenelemente 41 auf, die Teile der Gehäusekassette 7 sind, d. h. einstückig mit der Gehäusekassette 7 ausgebildet sind, und sich parallel zu der Lagerachse 37 zu der Deckelplatte 9 hin erstrecken. Die Deckelplatte 9 weist für jedes Zapfenelement 41 eine zu dem Zapfenelement 41 korrespondierende zweite Deckelaussparung 43 auf, in die das Zapfenelement 43 hineinragt. Jede zweite Deckelaussparung 43 ist als ein Durchloch in der Deckelplatte 9 ausgebildet. Durch die in die zweiten Deckelaussparungen 43 hineinragenden Zapfenelemente 41 sind die Gehäusekassette 7 und die Deckelplatte 9 formschlüssig miteinander verbunden. Diese formschlüssige Verbindung nimmt Querkräfte auf, die in der Ebene der Deckelplatte 9 über die Lagerachse 37 bei Drehungen des Steuerhebels 29 auf die Deckelplatte 9 ausgeübt werden. Dadurch entlastet die durch die Zapfenelemente 41 hergestellte formschlüssige Verbindung der Deckelplatte 9 mit der Gehäusekassette 7 die Schraubverbindungen 27, so dass eine Reduzierung der Schraubenvorspannungen der Schraubverbindungen 27 aufgrund hoher Querkräfte und eine dadurch verursachte Bewegung der Deckelplatte 9 relativ zu der Gehäusekassette 7 verhindert werden.The gear housing 5 also has two pin elements 41, which are parts of the housing cassette 7, i. H. are formed in one piece with the housing cassette 7 and extend parallel to the bearing axis 37 towards the cover plate 9. For each pin element 41, the cover plate 9 has a second cover recess 43 which corresponds to the pin element 41 and into which the pin element 43 projects. Each second cover recess 43 is designed as a through hole in the cover plate 9. The housing cassette 7 and the cover plate 9 are positively connected to one another by the pin elements 41 protruding into the second cover recesses 43. This form-fitting connection absorbs transverse forces which are exerted on the cover plate 9 in the plane of the cover plate 9 via the bearing axis 37 when the control lever 29 is rotated. As a result, the positive connection of the cover plate 9 to the housing cassette 7 established by the pin elements 41 relieves the screw connections 27, so that a reduction in the screw prestresses of the screw connections 27 due to high transverse forces and a resulting movement of the cover plate 9 relative to the housing cassette 7 are prevented.

Zur Kopplung der ersten Hebelseite 31 mit dem ersten Schaltkontakt ist die erste Hebelseite 31 über eine durch eine erste Stegaussparung 44 in dem Mittelsteg 21 in das Getriebegehäuse 5 hineinragende Antriebsstange 45 mit dem ersten Schaltkontakt verbunden. Dazu weist die erste Hebelseite 31 zwei Koppelnasen 47 auf, und ein steuerhebelseitiger Endbereich 49 der Antriebsstange 45 weist für jede Koppelnase 47 ein Langloch 51 auf, in dem die Koppelnase 47 geführt ist. Der Endbereich 49 der Antriebsstange 45 weist zwei voneinander beabstandete und zueinander parallele Endplatten 53 auf, die jeweils eines der Langlöcher 51 aufweisen. Die erste Hebelseite 31 ragt in den Bereich zwischen den beiden Endplatten 53 hinein. Die Koppelnasen 47 befinden sich auf sich gegenüber liegenden Seiten der ersten Hebelseite 31 und stehen von der ersten Hebelseite 31 jeweils zu der dort angeordneten Endplatte 53 ab, so dass sie in das Langloch 51 dieser Endplatte 53 hineinragen.To couple the first lever side 31 to the first switching contact, the first lever side 31 is connected to the first switching contact via a drive rod 45 protruding through a first web recess 44 in the central web 21 into the gear housing 5. For this purpose, the first lever side 31 has two coupling lugs 47, and an end region 49 of the drive rod 45 on the control lever side has an elongated hole 51 for each coupling lug 47 in which the coupling lug 47 is guided. The end region 49 of the drive rod 45 has two of each other spaced and mutually parallel end plates 53 which each have one of the elongated holes 51. The first lever side 31 protrudes into the area between the two end plates 53. The coupling lugs 47 are located on opposite sides of the first lever side 31 and protrude from the first lever side 31 towards the end plate 53 arranged there, so that they protrude into the elongated hole 51 of this end plate 53.

Die zweite Hebelseite 33 ist mit dem zweiten Schaltkontakt über einen in den Figuren 1 und 2 nicht sichtbaren Bolzen gekoppelt. Der Bolzen ist in einer in das Getriebegehäuse 5 hineinragenden Führungsschiene 55 durch eine in den Figuren 1 und 2 nicht sichtbare zweite Stegaussparung in dem Mittelsteg 21 geführt. Die zweite Hebelseite 33 ragt in die Führungsschiene 55 hinein und ist gabelförmig mit zwei Zinken 57, 59 ausgebildet, zwischen die der Bolzen einfährt. Eine Bewegung des Bolzens in einer von dem ersten Gehäuseteil 11 zu dem zweiten Gehäuseteil 13 weisenden Richtung bewirkt eine Drehung des Steuerhebels 29, die über die Koppelnasen 47 die Antriebsstange 45 in entgegengesetzer Richtung bewegt. Der Bolzen wird zusammen mit dem zweiten Schaltkontakt beispielsweise durch einen nicht dargestellten Antrieb des Leistungsschalters 1 angetrieben. Durch das Getriebe 3 wird der erste Schaltkontakt entgegengesetzt zu dem zweiten Schaltkontakt bewegt.The second lever side 33 is connected to the second switching contact via a Figures 1 and 2 not visible bolt coupled. The bolt is in a protruding into the gear housing 5 guide rail 55 through a Figures 1 and 2 The second web recess, which is not visible, is guided in the central web 21. The second lever side 33 protrudes into the guide rail 55 and is fork-shaped with two prongs 57, 59, between which the bolt moves. A movement of the bolt in a direction pointing from the first housing part 11 to the second housing part 13 causes a rotation of the control lever 29 which, via the coupling lugs 47, moves the drive rod 45 in the opposite direction. The bolt is driven together with the second switching contact, for example by a drive of the circuit breaker 1 (not shown). The gear 3 moves the first switch contact in the opposite direction to the second switch contact.

Ein zu dem in den Figuren 1 und 2 dargestellten Ausführungsbeispiel alternatives Ausführungsbeispiel sieht vor, dass die Zapfenelemente 41 nicht einstückig mit der Gehäusekassette 7, sondern einstückig mit der Deckelplatte 9 ausgeführt und formschlüssig in zu ihnen korrespondierende Kassettenaussparungen in der Gehäusekassette 7 hineinragen. In weiteren Ausführungsbeispielen sind die Zapfenelemente 41 weder einstückig mit der Gehäusekassette 7 noch mit der Deckelplatte 9 ausgeführt, sondern als Stiftelemente, beispielsweise als Spannstifte, oder als Passschrauben ausgeführt, die durch zweite Deckelaussparungen 43 in der Deckelplatte 9 in Kassettenaussparungen in der Gehäusekassette 7 geführt und dort fixiert sind. In weiteren Ausführungsbeispielen ist die Lagerachse 37 nicht einstückig mit der Gehäusekassette 7, sondern einstückig mit der Deckelplatte 9 ausgeführt und ragt in eine zu Lagerachse 37 korrespondierende Kassettenaussparung in der Gehäusekassette 7 hinein, oder die Lagerachse 37 ist weder einstückig mit der Gehäusekassette 7 noch einstückig mit der Deckelplatte 9, sondern als ein mit der Gehäusekassette 7 und der Deckelplatte 9 verbundenes Achsenelement, beispielsweise als ein Bolzen, ausgeführt. Die Kassettenaussparungen können in den genannten Ausführungsbeispielen jeweils als Durchlöcher oder als Sacklöcher ausgeführt sein. Bei ausreichender Dicke der Deckelplatte 9 können ferner auch die erste Deckelaussparung 39 und/oder die zweiten Deckelaussparungen 43 des in den Figuren 1 und 2 dargestellten Ausführungsbeispiels als Sacklöcher statt als Durchlöcher ausgeführt sein.One to the one in the Figures 1 and 2 The alternative embodiment shown provides that the pin elements 41 are not made in one piece with the housing cassette 7, but in one piece with the cover plate 9 and protrude in a form-fitting manner into corresponding cassette recesses in the housing cassette 7.
