Description

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 by moving one Rocker, a rocker arm or a rotary toggle attached Force via a key switch to a moving circuit switching contact is transferable.

Leistungsschalter werden zum Schalten unterschiedlicher Schaltleistungen in unterschiedlichen Größen hergestellt. Aus physikalisch-technischen oder fertigungstechnischen Gründen hängt der Gesamtaufbau eines solchen Leistungsschalters, beispielsweise 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 Betätigung des Schalters möglichst zentral an einer Bedienfläche erfolgen.Circuit breakers are used to switch different Switching capacities manufactured in different sizes. Out physical-technical or manufacturing-related reasons depends on the overall structure of such a circuit breaker, for example the location of the key switch or various Triggers, essentially depending on the maximum switching capacity. Furthermore, depending on the customer's request, the planned Application and type of actuation (manual or remote control, actuation via rockers, rocker arms or rotary knobs) the switch as centrally as possible on a control surface respectively.

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 is proposed different switch locks with their own, specially coordinated actuators use. 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 als 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 eines Betätigungsgliedes, daß der Stößel bei jeder Betätigung auf eine Kulissenfläche 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.DE 36 06 508 C2 discloses a switching mechanism for a electrical installation device for optional use as Pushbutton switches, pushbuttons, rocker switches or rocker switches using a link-shaped flip-flop for actuating a Contact spring that can be moved in two switching positions. The Tilting member is in operative connection with a plunger Actuator that the plunger with each actuation hits a backdrop surface and then a pivoting movement of the flip-flop in its opposite position he follows. An actuator is assigned to the switching mechanism, the rocker member with both the contact spring as also with the in the switch housing between the flip-flop and the freely movable end of the contact spring is rotatably arranged Actuator interacts. The switching mechanism can be with the help of the actuator either switch so that this can be used either as a switch or as a button. With this switching mechanism, however, no different Compensate sizes of circuit breakers.

Aus dem G 90 01 424.3 U1 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 elastische 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 Leistungsschaltern ausgleichen.From the G 90 01 424.3 U1 is an electrical circuit breaker known of a tiltable or sledge-like adjustable operating button for optional operation has two movable contacts. This is between one Starting position, the open position of the two movable Contacts compared to the fixed contacts, and two consecutive positions that the Closing one or both movable contacts with the fixed contacts are assigned, movable back and forth. The contact is a cooperating with the actuation button elastic locking device for determining the positions assigned to the control button, the elastic Locking element is formed by an elastic tongue, which are connected to a carrier for the fixed contacts is. The known breaker switch has different Actuators on; however, it can also no different sizes of circuit breakers compensate.

Furthermore, the seesaw is against a toothed rocker with counter wheel and rotary knob can be exchanged.

Um die unterschiedlichen Einbaulagen auszugleichen, ist nach einer anderen Weiterbildung der Erfindung zwischen die Zahnwippe und das Gegenrad eine Antriebswelle einfügbar.To compensate for the different installation positions, is after another development of the invention between the rocker and the counter wheel insertable a drive shaft.

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 with the invention are in particular in the fact that expensive custom-made products differ Switch locks are avoided, and that one for different large circuit breakers suitable, cheaper to manufacture Basic equipment can be used in larger numbers.
