Said equipment can be adapted to different size requirements by exchanging, omitting or adding of different individual components.

Description

Beschreibungdescription
Leistungsschalter zum Schalten elektrischer StromkreiseCircuit breaker for switching electrical circuits
Die Erfindung betrifft einen Leistungsschalter zum Schalten elektrischer Stromkreise, bei dem die durch Bewegen einer Wippe, eines Kipphebels oder eines Drehknebels aufgebrachte Kraft über ein Schaltschloß an ein bewegliches, den Stromkreis schaltendes Schaltstück übertragbar ist.The invention relates to a circuit breaker for switching electrical circuits, in which the force applied by moving a rocker, a rocker arm or a rotary knob can be transmitted via a switch lock to a movable switching element which switches the circuit.
Leistungsschalter werden zum Schalten unterschiedlicher Schaltleistungen in unterschiedlichen Größen hergestellt. Aus physikalisch-technischen oder fertigungstechnischen Gründen hängt der Gesamtaufbau eines solchen Leistungsschalters , bei- spielsweise die Lage des Schaltschlosses oder verschiedener Auslöser, wesentlich von der maximalen Schaltleistung ab. Ferner muß je nach Wunsch des Bestellers, nach der geplanten Anwendung und nach der Art der Betätigung (Hand- oder Fernantrieb, über Wippen, Kipphebel oder Drehknebel) die Betäti- gung des Schalters möglichst zentral an einer Bedienfläche erfolgen.Circuit breakers are manufactured in different sizes for switching different switching capacities. For physical-technical or manufacturing reasons, the overall structure of such a circuit breaker, for example the position of the switch lock or various triggers, depends essentially on the maximum switching capacity. Furthermore, depending on the customer's request, the planned application and the type of actuation (manual or remote drive, rocker, rocker arm or rotary knob), the switch must be actuated as centrally as possible on a control surface.
Um die unterschiedlichen Baugrößen auszugleichen, ist vorgeschlagen worden, verschiedene Schaltschlösser mit eigenen, speziell aufeinander abgestimmten Betätigungselementen zu verwenden. Das hat den Nachteil, daß diese speziellen Schaltschlösser sehr teuer sind.In order to compensate for the different sizes, it has been proposed to use different switch locks with their own, specially coordinated actuating elements. This has the disadvantage that these special switch locks are very expensive.
Die DE 36 06 508 C2 offenbart einen Schaltmechanismus für ein elektrisches Installationsgerät zum wahlweisen Einsatz alsDE 36 06 508 C2 discloses a switching mechanism for an electrical installation device for optional use as
Tastschalter, Taster, Wippschalter oder Wipptaster unter Verwendung eines kulissenförmigen Kippgliedes zur Betätigung einer in zwei Schaltstellungen überführbaren Kontaktfeder. Das Kippglied steht derart in Wirkverbindung mit einem Stößel ei- nes Betätigungsgliedes, daß der Stößel bei jeder Betätigung auf eine Kulissenflache stößt und hierauf eine Schwenkbewegung des Kippgliedes in seine jeweils entgegengesetzte Stellung erfolgt. Dem Schaltmechanismus ist ein Stellglied zugeordnet, wobei das Kippglied sowohl mit der Kontaktfeder als auch mit dem im Schaltergehäuse zwischen dem Kippglied und dem frei beweglichen Ende der Kontaktfeder drehbar angeordneten Stellglied zusammenwirkt. Der Schaltmechanismus läßt sich mit Hilfe des Stellgliedes wahlweise derart umstellen, daß dieser entweder als Schalter oder als Taster verwendbar ist. Mit diesem Schaltmechanismus lassen sich jedoch keine unterschiedlichen Baugrößen von Leistungsschaltern ausgleichen.Pushbutton switches, pushbuttons, rocker switches or rocker switches using a sliding rocker element to actuate a contact spring that can be moved into two switch positions. The tilting member is operatively connected to a plunger of an actuating member such that the plunger is actuated each time it is actuated encounters a backdrop surface and thereupon a pivoting movement of the tilting member takes place in its opposite position. An actuator is assigned to the switching mechanism, the rocker element cooperating both with the contact spring and with the actuator which is rotatably arranged in the switch housing between the rocker element and the freely movable end of the contact spring. The switching mechanism can be optionally changed with the help of the actuator so that it can be used either as a switch or as a button. With this switching mechanism, however, different sizes of circuit breakers cannot be compensated for.
Aus dem G 90 01 424.3 Ul ist ein elektrischer Unterbrecherschalter bekannt, der einen kippbaren oder schlittenartig verstellbaren Betätigungsknopf zum wahlweisen Betätigen zweier beweglicher Kontakte aufweist. Dieser ist zwischen einer Ausgangsstellung, die der Offenstellung der beiden beweglichen Kontakte gegenüber den feststehenden Kontakten entspricht, und zwei aufeinanderfolgenden Stellungen, die dem Schließen eines oder beider beweglicher Kontakte mit den feststehenden Kontakten zugeordnet sind, hin und her bewegbar. Dem Kontakt ist ein mit dem Betätigungsknopf zusammenwirkendes elastisches Feststellorgan zum Bestimmen der Stellungen des Betätigungsknopfes zugeordnet, wobei das elasti- sehe Feststellorgan durch eine elastische Zunge gebildet ist, die mit einem Träger für die feststehenden Kontakte verbunden ist. Der bekannte Unterbrecherschalter weist zwar unterschiedliche Betätigungsorgane auf; es lassen sich jedoch ebenfalls keine unterschiedlichen Baugrößen von Leistungs- Schaltern ausgleichen.From the G 90 01 424.3 Ul an electrical interrupter switch is known, which has a tiltable or slide-like adjustable actuating button for the optional actuation of two movable contacts. This can be moved back and forth between an initial position, which corresponds to the open position of the two movable contacts with respect to the fixed contacts, and two successive positions, which are associated with the closing of one or both movable contacts with the fixed contacts. The contact is associated with an elastic locking element which interacts with the actuating button for determining the positions of the operating button, the elastic locking element being formed by an elastic tongue which is connected to a carrier for the fixed contacts. The known breaker switch has different actuators; however, it is also not possible to compensate for different sizes of circuit breakers.
Der Erfindung liegt die Aufgabe zugrunde, einen Leistungsschalter der eingangs erwähnten Art so zu gestalten, daß die teuren Ausführungen von unterschiedlichen Schaltschlössern vermieden werden. Diese Aufgabe wird nach Anspruch 1 dadurch gelöst, daß das Schaltschloß eine für unterschiedliche Baugrößen des Lei- stungsschalters gleiche Grundausstattung aufweist, die durch Austauschen, Weglassen oder Hinzufügen verschiedener Einzelkomponenten an die Anforderungen für die unterschiedlichen Baugrößen anpaßbar ist.The invention has for its object to design a circuit breaker of the type mentioned so that the expensive designs of different switch locks are avoided. This object is achieved according to claim 1 in that the switch lock has the same basic equipment for different sizes of the circuit breaker, which can be adapted to the requirements for the different sizes by exchanging, omitting or adding different individual components.
Nach einer Weiterbildung der Erfindung ist vorgesehen, daß die Wippe gegen einen Kipphebel austauschbar ist.According to a development of the invention, it is provided that the rocker can be exchanged for a rocker arm.
Um den Eingriff eines Gegenrades und des damit formschlüssig verbundenen Knebels zu ermöglichen, ist nach einer weiteren Fortbildung der Erfindung vorgesehen, daß die Wippe gegen eine Zahnwippe austauschbar ist. Ferner ist die Wippe gegen eine Zahnwippe mit Gegenrad und Drehknebel austauschbar.In order to enable the engagement of a counter wheel and the toggle connected to it in a form-fitting manner, according to a further development of the invention it is provided that the rocker can be exchanged for a toothed rocker. Furthermore, the rocker can be exchanged for a toothed rocker with counter wheel and rotary knob.
Um die unterschiedlichen Einbaulagen auszugleichen, ist nach einer anderen Weiterbildung der Erfindung zwischen die Zahnwippe und das Gegenrad eine Antriebswelle einfügbar.In order to compensate for the different installation positions, according to another development of the invention, a drive shaft can be inserted between the tooth rocker and the counter wheel.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß teure Spezialanfertigungen unterschiedlicher Schaltschlösser vermieden werden, und daß eine für verschieden große Leistungsschalter geeignete, billiger herstellbare Grundausstattung in größerer Stückzahl verwendet werden kann.The advantages achieved by the invention are, in particular, that expensive special designs of different switch locks are avoided, and that a basic equipment suitable for differently sized circuit breakers, which can be manufactured more cheaply, can be used in large numbers.
