Definitions
- the invention relates to a circuit breaker, the switch lock consists essentially of a rotatably mounted pawl, which rotatably engages over a contact lever and stands on a release member, and a manual control member, which is connected by a spring outside its pivot point to the pawl next to its pivot point .
- a known miniature circuit breaker US Pat. No. 2,190,517
- US Pat. No. 2,190,517 therefore requires only a few components, particularly when building a switch lock. Nevertheless, he needs a compression spring for manual actuation of the contact lever and the manual control element, as well as another spring that opens the contact lever when it is released.
- the invention is based on the knowledge that the known circuit breaker can still be fundamentally improved and can be upgraded for today's requirements.
- the invention has for its object to develop a circuit breaker using a Continuously operating switch lock, i.e. without a spring-loaded switching mechanism, needs only one spring.
- the pivot point of the pawl forms a ratchet lever which is guided in a backdrop and is connected eccentrically to the pivot point of the manual control element with this and that the spring engages the contact lever.
- the spring between the manual actuator and the pawl is therefore not directly connected to the pawl, but indirectly via the contact lever.
- Such a circuit breaker with a continuously operating switch lock has the advantage that bouncing phenomena on the contacts are largely avoided. It comes with a spring that enables the switching movement and the contact pressure, the handle reset and the release mechanism.
- the spring acts as a tension spring on the contact lever between its axis of rotation and the fulcrum of the ratchet lever and that the fixed contact piece associated with the contact piece of the contact lever is arranged on the side facing the pawl which faces away from the manual control element.
- a circuit breaker has a particularly simple structure.
- a particularly simple structure can be achieved if that Manual control member is cylindrical and the pawl rests on a rail magnet known per se. This further simplifies the structure.
- the pawl 1 has a rotatably mounted pawl 1, a contact lever 2 and a manual control element 3 in its switching lock.
- the pawl stands on a trigger element 4.
- this is a rail magnet, that is to say a combined thermal and magnetic release, as is known per se (US Pat. No. 3,081,368, French Pat. No. 1,309,280).
- the fulcrum of the pawl 1 forms a pawl lever 6 at 5, which is guided in a link 7 so that an approximately constant distance from the latching point 8 is created.
- the pawl lever 6 is connected eccentrically to the fulcrum 9 of the manual control member 3.
- a spring 10 in the exemplary embodiment a tension spring, engages on the contact lever 2, which is partially overlapped by the pawl 1 in a U-shape and is held rotatably at 11.
- a contact piece 12 is arranged on the contact lever 2 and a contact piece 13 is arranged on the fixed contact. Extinguishing plates can be arranged between the contact pieces in a known manner, but are also unnecessary for simple switching tasks.
- the current path via trigger 4 which can also be a conventional electromagnetic and thermal trigger, can run via a stranded wire of a known type, which is not shown, to the contact lever 2 and from there to the contact piece 13 and a connecting terminal.
- Another connection terminal can be arranged on the other side of the circuit breaker at the trigger element 4.
- the circuit breaker can be snapped onto mounting rails in the usual manner with the snap device 14.
- the spring 10 acts as a tension spring on the contact lever 2 between its axis of rotation 11 and the fulcrum 5 of the pawl lever 6, it is advantageous if the fixed contact piece 13 associated with the contact piece 12 of the contact lever 2 is arranged on the side of the pawl 1 by the manual control element 3 is turned away.
- the latch lever 6 is rotatably connected to the manual control element 3 at 15.
- the switching state according to FIG. 1 changes to that according to FIG. 2.
- the manual control element 3 forms a guide lip 16 for the spring 10. It is formed on the manual control element 3 in such a way that in the position of free release when the manual control element 3 is held by hand and the circuit breaker responds and the trigger element 4 releases the pawl 1 , then the imaginary center line of the spring 10 approximately up to the connecting line of the ratchet lever 6 and pawl 1 on the one hand and pivot point 9 of the hand control on the other hand at least approximately raises.
- the switching position of the free trip is illustrated in Fig. 3.
- the spring 10 can contract quite a bit and an unstable state is formed with regard to the torque caused by the tensile force of the spring 10, so that the internal spring forces which want to bring about a straight position, after releasing the manual control element 1 into the position transfer to Fig. 1.
- the manual control element 3 is configured in the form of a roller, as shown in the figures.
- the hand control 1 To reset from the free release according to FIG. 3 into the switch-on position, the hand control 1 only needs to be transferred from the switch-off position to the switch-on position after being released. 3 moves clockwise to the right, the pawl lever 6 lifts the pawl 1 under the tensile force of the spring 10 to the latching point 8. During this process, the position of the ratchet lever 6 and the imaginary axis of the spring 10 increasingly diverge until they have reached the position shown in FIG. 1. As a result, the torque exerted by the spring 10 becomes increasingly larger, so that an increasing releasing force is achieved.

Description
Die Erfindung bezieht sich auf einen Leitungsschutzschalter, dessen Schaltschloß im wesentlichen besteht aus einer drehbar gelagerten Klinke, die einen Kontakthebel drehbeweglich übergreift und auf einem Auslöseorgan aufsteht, und aus einem Handbedienungsorgan, das durch eine Feder außerhalb dessen Drehpunktes mit der Klinke neben deren Drehpunkt verbunden ist. Ein solcher bekannter Leitungsschutzschalter (US-PS 2 190 517) kommt also besonders beim Aufbau eines Schaltschlosses mit wenigen Bauteilen aus. Dennoch benötigt er eine Druckfeder zum manuellen Betätigen des Kontakthebels und des Handbedienungsorgans sowie eine weitere Feder, die beim Entklinken den Kontakthebel öffnet.The invention relates to a circuit breaker, the switch lock consists essentially of a rotatably mounted pawl, which rotatably engages over a contact lever and stands on a release member, and a manual control member, which is connected by a spring outside its pivot point to the pawl next to its pivot point . Such a known miniature circuit breaker (US Pat. No. 2,190,517) therefore requires only a few components, particularly when building a switch lock. Nevertheless, he needs a compression spring for manual actuation of the contact lever and the manual control element, as well as another spring that opens the contact lever when it is released.
Zum Wiedereinschalten des bekannten Leitungsschutzschalters muß dieser zunächst nach einer Freiauslösung von Hand in die Ausschaltstellung und dann in die Einschaltstellung zurückgeschaltet werden. Die theoretisch erforderlichen Federn, eine für Schaltbewegung, eine für Kontaktdruck und eine für Griffrückstellung und Rückverklinkung werden also nur um eine vermindert.To switch the known circuit breaker back on, it must first be switched back to the switch-off position and then back to the switch-on position after a free trip. The theoretically required springs, one for switching movement, one for contact pressure and one for returning the handle and latching back, are therefore reduced by only one.
Der Erfindung liegt die Erkenntnis zugrunde, daß der bekannte Leitungsschutzschalter noch grundsätzlich verbessert werden kann und für heutige Anforderungen sich ertüchtigen läßt.The invention is based on the knowledge that the known circuit breaker can still be fundamentally improved and can be upgraded for today's requirements.
Der Erfindung liegt die Aufgabe zugrunde, einen Leitungsschutzschalter zu entwickeln, der unter Verwendung eines kontinuierlich arbeitenden Schaltschlosses, also ohne Sprungschaltwerk, mit lediglich einer Feder auskommt.The invention has for its object to develop a circuit breaker using a Continuously operating switch lock, i.e. without a spring-loaded switching mechanism, needs only one spring.
Die Lösung der geschilderten Aufgabe besteht nach der Erfindung darin, daß den Drehpunkt der Klinke ein Klinkenhebel bildet, der in einer Kulisse geführt ist und exzentrisch zum Drehpunkt des Handbedienungsorgans mit diesem verbunden ist und daß die Feder am Kontakthebel angreift. Die Feder zwischen Handbetätigungsorgan und Klinke ist also nicht unmittelbar mit der Klinke, sondern indirekt über den Kontakthebel verbunden. Ein solcher Leitungsschutzschalter mit kontinuierlich arbeitendem Schaltschloß weist den Vorteil auf, daß Prellerscheinungen auf den Kontakten weitgehend vermieden werden. Er kommt mit einer Feder aus, die die Schaltbewegung und den Kontaktdruck, die Griffrückstellung und die Rückverklinkung ermöglicht.The solution of the described task is according to the invention that the pivot point of the pawl forms a ratchet lever which is guided in a backdrop and is connected eccentrically to the pivot point of the manual control element with this and that the spring engages the contact lever. The spring between the manual actuator and the pawl is therefore not directly connected to the pawl, but indirectly via the contact lever. Such a circuit breaker with a continuously operating switch lock has the advantage that bouncing phenomena on the contacts are largely avoided. It comes with a spring that enables the switching movement and the contact pressure, the handle reset and the release mechanism.
Es ist günstig, daß die Feder bei Ausbildung als Zugfeder am Kontakthebel zwischen dessen Drehachse und den Drehpunkt des Klinkenhebels angreift und daß das dem Kontaktstück des Kontakthebels zugeordnete Festkontaktstück auf der Seite zur Klinke angeordnet ist, die vom Handbedienungsorgan abgewandt ist. Ein solcher Leitungsschutzschalter weist einen besonders einfachen Aufbau auf.It is favorable that the spring acts as a tension spring on the contact lever between its axis of rotation and the fulcrum of the ratchet lever and that the fixed contact piece associated with the contact piece of the contact lever is arranged on the side facing the pawl which faces away from the manual control element. Such a circuit breaker has a particularly simple structure.
Die Griffrückstellung nach einer Freiauslösung wird in einfacher Weise erzielt, wenn das Handbedienungsorgan eine Führungslippe für die Feder bildet, die in der Stellung der Freiauslösung deren gedachten Mittellinie etwa bis zur Verbindungslinie von Klinkenhebel und Klinke einerseits und Drehpunkt des Handbedienungsorgans andererseits anhebt.The reset of the handle after a free release is achieved in a simple manner if the manual control element forms a guide lip for the spring, which in the position of the free release raises its imaginary center line approximately up to the connecting line between the ratchet lever and pawl on the one hand and the fulcrum of the manual control element on the other hand.
Einen besonders einfachen Aufbau erzielt man, wenn das Handbedienungsorgan walzenförmig ausgebildet ist und die Klinke auf einem an sich bekannten Schienenmagneten aufliegt. Dadurch wird der Aufbau noch weiter vereinfacht.A particularly simple structure can be achieved if that Manual control member is cylindrical and the pawl rests on a rail magnet known per se. This further simplifies the structure.
Die Erfindung soll anhand eines in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispiels näher erläutert werden:
- In Fig. 1 ist der Leitungsschutzschalter in der Ausschaltstellung teilweise aufgebrochen wiedergegeben.
- In Fig. 2 ist.der Leitungsschutzschalter in der Darstellungsweise nach Fig. 1 in seiner Einschaltstellung wiedergegeben.
- In Fig. 3 ist der Leitungsschutzschalter bei Freiauslösung, wenn das Handbedienungsorgan also während des Ansprechens des Leitungsschutzschalters festgehalten wird, dargestellt. Wenn man das Handbedienungsorgan losläßt, wird es in die Lage nach Fig. 1 überführt, wodurch es die Ausschaltstellung anzeigt.
- In Fig. 1 the circuit breaker is shown partially broken open.
- In Fig. 2 the circuit breaker in the representation of Fig. 1 is shown in its on position.
- In Fig. 3, the miniature circuit breaker is shown in the case of free tripping, if the manual control element is thus held during the response of the miniature circuit breaker. If you let go of the manual control element, it is transferred to the position shown in Fig. 1, whereby it indicates the off position.
Der Leitungsschutzschalter nach Fig. 1 weist bei seinem Schaltschloß eine drehbar gelagerte Klinke 1, einen Kontakthebel 2 und ein Handbedienungsorgan 3 auf. Die Klinke steht auf einem Auslöseorgan 4 auf. Im Ausführungsbeispiel ist dies ein Schienenmagnet, also ein kombinierter thermischer und magnetischer Auslöser, wie er an sich bekannt ist (US-PS 3 081 368, FR-PS 1 309 280). Den Drehpunkt der Klinke 1 bildet bei 5 ein Klinkenhebel 6, der in einer Kulisse 7 so geführt ist, daß etwa konstanter Abstand zur Verklinkungsstelle 8 entsteht. Der Klinkenhebel 6 ist exzentrisch zum Drehpunkt 9 des Handbedienungsorgans 3 mit diesem verbunden. Eine Feder 10, im Ausführungsbeispiel eine Zugfeder, greift am Kontakthebel 2 an, der von der Klinke 1 teilweise U-förmig übergriffen wird und bei 11 drehbeweglich gehalten ist.1 has a rotatably mounted pawl 1, a contact lever 2 and a
Am Kontakthebel 2 ist ein Kontaktstück 12 und am Festkontakt ein Kontaktstück 13 angeordnet. Zwischen den Kontaktstücken können in bekannter Weise Löschbleche angeordnet werden, die sich für einfache Schaltaufgaben jedoch auch erübrigen. Der Strompfad über Auslöser 4, der auch ein üblicher elektromagnetischer und thermischer Auslöser sein kann, kann über eine Litzenleitung bekannter Art, dieinicht dargestellt ist, zum Kontakthebel 2 verlaufen und von dort zum Kontaktstück 13 und eine Anschlußklemme. Eine weitere Anschlußklemme kann auf der anderen Seite des Leitungsschutzschalters beim Auslöseorgan 4 angeordnet sein. Der Leitungsschutzschalter kann mit der Schnappvorrichtung 14 in üblicher Weise auf Tragschienen aufgeschnappt werden.A contact piece 12 is arranged on the contact lever 2 and a
Wenn die Feder 10 bei Ausbildung als Zugfeder am Kontakthebel 2 zwischen dessen Drehachse 11 und dem Drehpunkt 5 des Klinkenhebels 6 angreift, ist günstig, wenn das dem Kontaktstück 12 des Kontakthebels 2 zugeordnete Festkontaktstück 13 auf der Seite der Klinke 1 angeordnet ist, die vom Handbedienungsorgan 3 abgewandt ist. Ein solcher Aufbau ist in Fig. 1 dargestellt. Im Ausführungsbeispiel ist der Klinkenhebel 6 mit dem Handbedienungsorgan 3 bei 15 drehbeweglich verbunden.If the
Wenn der Leitungsschutzschalter in seine Einschaltstellung überführt wird, geht der Schaltzustand nach Fig. 1 in den nach Fig. 2 über. Nach einer Weiterbildung bildet das Handbedienungsorgan 3 für die Feder 10 eine Führungslippe 16. Sie ist am Handbedienungsorgan 3 so ausgebildet, daß in der Stellung der Freiauslösung, wenn das Handbedienungsorgan 3 von Hand festgehalten wird und der Leitungsschutzschalter anspricht und das Auslöscorgan 4 die Klinke 1 freigibt, dann die gedachte Mittellinie der Feder 10 etwa bis zur Verbindungslinie von Klinkenhebel 6 und Klinke 1 einerseits und Drehpunkt 9 des Handbedienungsorgans 1 andererseits zumindest in etwa anhebt. Die Schaltstellung der Freiauslösung ist in Fig. 3 veranschaulicht. In dieser Schaltstellung kann sich die Feder 10 ziemlich zusammenziehen und es bildet sich hinsichtlich des von der Zugkraft der Feder 10 bewirkten Drehmoments ein labiler Zustand aus, so daß die inneren Federkräfte, die eine gerade Stellung bewirken möchten, nach Loslassen das Handbedienungsorgan 1 in die Stellung nach Fig. 1 überführen.When the circuit breaker is moved to its on position, the switching state according to FIG. 1 changes to that according to FIG. 2. According to a further development, the
Im Ausführungsbeispiel ist das Handbedienungsorgan 3 walzenförmig ausgebildet, wie es in den Figuren dargestellt ist. Zum Rückstell-en von der Freiauslösung nach Fig. 3 in die Einschaltstellung braucht das Handbedienungsorgan 1, nachdem man es losgelassen hat, nur von der Ausschaltstellung in die Einschaltstellung überführt zu werden. Wenn das Handbedienungsorgan 1 nach der Freiauslösung gemäß Fig. 3 sich im Uhrzeigersinn nach rechts bewegt, hebt der Klinkenhebel 6 die Klinke 1 unter der Zugkraft der Feder 10 bis zur Verklinkungsstelle 8 an. Während dieses Vorgangs laufen die Stellung des Klinkenhebels 6 und die gedachte Achse der Feder 10 zunehmend auseinander, bis sie die Lage nach Fig. 1 erreicht haben. Dadurch wird das von der Feder 10 ausgeübte Drehmoment zunehmend größer, so daß eine wachsende Rückverklinkungskraft erzielt wird.In the exemplary embodiment, the
