As a result, the support plate 20 is positively held on the wall 5 of the circuit breaker.

Weiterhin weist die Trägerplatte 20 ein zweites Teil 36 auf, welches aus Metall besteht. Im Ausführungsbeispiel besteht das zweite Teil 36 aus Stahl. Das erste Teil 30 ist mit dem zweiten Teil 36 starr verbunden. Im Ausführungsbeispiel sind das erste Teil 30 und das zweite Teil 36 mittels Nieten 38 miteinander vernietet. Das zweite Teil 36 stellt einen Beschlag dar, der auf dem ersten Teil 30 aufgebracht ist. Das zweite Teil 36 weist einen plattenförmigen Bereich 40 auf. Dieser plattenförmige Bereich 40 ist im Ausführungsbeispiel mit dem ersten Teil 30 starr verbunden (hier: vernietet). Der plattenförmige Bereich 40 geht über in eine Auflagefläche 44 eines Befestigungsmittels 46. Die Auflagefläche 44 ist rechtwinklig zu dem plattenförmigen Bereich 40 angeordnet. Dies wird dadurch erreicht, dass das Material des zweiten Teils unter Bildung der Auflagefläche 44 abgewinkelt ist. Mit anderen Worten ist die Auflagefläche 44 senkrecht zur Ebene der Trägerplatte (Plattenebene) angeordnet. Wie in Figur 2 dargestellt, erstreckt sich die Auflagefläche 44 der an dem Leistungsschalter 1 gehalterten bzw. montierten Trägerplatte oberhalb der oberen Gehäusekante 8 des Gehäuses des Leistungsschalters 1.Furthermore, the support plate 20 on a second part 36, which consists of metal.

The Kipphebelverriegelung 74 is screwed by means not shown screws with the other support plate 72.

In Figur 7 sind die beiden Leistungsschalter 1 und 70 der Figur 6 in einer Draufsicht dargestellt. Hier ist besonders gut zu erkennen, wie die schwalbenschwanzförmigen Halterungsmittel 32 der Trägerplatte 20 in die Ausnehmung 7 des Leistungsschalters 1 eingreifen. An dieser Stelle soll darauf hingewiesen werden, dass die Kipphebelverriegelung 74 mit Absperrmöglichkeit nur ein Beispiel für ein Leistungsschalter-Zubehörteil darstellt. Selbstverständlich können mittels der Trägerplatte 20 auch andere Leistungsschalter-Zubehörteile an dem Leistungsschalter befestigt werden, beispielsweise eine Bowdenzugverriegelung, eine Kipphebelblockiervorrichtung, ein Handdrehantrieb, ein Motorantrieb oder ähnliches. Auch ist es natürlich möglich, ein Zubehörteil mittels nur einer Trägerplatte an nur einem Leistungsschalter zu befestigen.In FIG. 7 the two power switches 1 and 70 of Figure 6 are shown in a plan view. Here is particularly well to see how the dovetail-shaped support means 32 of the support plate 20 in the recess 7 of the circuit breaker 1 intervene. At this point, it should be noted that the rocker arm lock 74 with shut-off feature is just one example of a circuit breaker accessory. Of course, by means of the support plate 20, other circuit breaker accessories are attached to the circuit breaker, such as a Bowden cable lock, a Kipphebelblockiervorrichtung, a hand rotary drive, a motor drive or the like. Also, it is of course possible to attach an accessory by means of only one carrier plate to only one circuit breaker.

Es wurde eine Trägerplatte beschrieben, mit der verschiedenste Leistungsschalter-Zubehörteile, auch Zubehörkomponenten genannt, extern an einen Leistungsschalter angebaut werden können. Dabei ist besonders vorteilhaft, dass an dem Leistungsschalter selbst keine Befestigungsmittel für die Leistungsschalter-Zubehörteile vorgesehen zu sein brauchen. Dadurch wird an dem Gehäuse des Leistungsschalters Platz gespart, wodurch sich der Leistungsschalter kompakt und mit einem geringen Volumen realisieren lässt.It has been described a carrier plate with which various circuit breaker accessories, also called accessory components, can be externally attached to a circuit breaker. It is particularly advantageous that on the circuit breaker itself no fastening means for the circuit breaker accessories need to be provided. As a result, space is saved on the housing of the circuit breaker, whereby the circuit breaker compact and can be realized with a small volume.

Die Trägerplatte kann beidseitig am Leistungsschalter befestigt werden. Dadurch wird die Anzahl der möglichen Befestigungsorte am Leistungsschalter erhöht und die Variantenvielfalt bei der Befestigung der Leistungsschalter-Zubehörteile wird vergrößert.The carrier plate can be attached to both sides of the circuit breaker. This increases the number of possible mounting locations on the circuit breaker and increases the variety of options in mounting the circuit breaker accessories.

Die Befestigungsmittel brauchen nicht unmittelbar bzw. direkt am Leistungsschalter vorgesehen zu sein, so dass sich keinerlei Einschränkungen für den Aufbau des Leistungsschalters ergeben. Durch Vermeidung solcher Einschränkungen geometrischer Art ergeben sich weitere optionale Möglichkeiten für die Gestaltung des Leistungsschalters. Weiterhin wird das Erscheinungsbild des Leistungsschalters durch fehlende Befestigungsmittel (wie fehlende Befestigungsbohrungen etc.) wesentlich ruhiger. Dies trägt zum Kundengefallen bei.The fasteners need not be provided directly or directly to the circuit breaker, so that there are no restrictions on the construction of the circuit breaker. By avoiding such geometric constraints, there are further optional possibilities for the design of the circuit breaker. Furthermore, the appearance of the circuit breaker by missing fasteners (such as missing mounting holes, etc.) is much quieter. This contributes to the customer favor.

Durch die Verwendung der erfindungsgemäßen Trägerplatte zum Tragen eines Leistungsschalter-Zubehörteils ergeben sich eine Reihe von Vorteilen: Durch die Platzeinsparung aufgrund fehlender Befestigungspunkte am Leistungsschalter erweitern sich die Möglichkeiten zur Nutzung anderer Systemkomponenten. Die Trägerplatte ermöglicht z.B. die universelle Montage von üblichen, frontseitig am Leistungsschalter zu montierenden Systemkomponenten, wie z. B. Kipphebelverriegelungen, Bowdenzugverriegelungen, Kipphebelblockiervorrichtungen, Handdrehantriebe oder Motorantriebe. Die Befestigung von solchen Leistungsschalter-Zubehörteilen im unmittelbaren Umfeld des Leistungsschalters (z. B. die Montage von externen Zubehörkomponenten an einer Grundplatte, auf die die Leistungsschalter montiert sind) ist nicht notwendig. Somit wird die Montage der Leistungsschalter-Zubehörteile wesentlich erleichtert.The use of the carrier plate according to the invention for carrying a circuit breaker accessory results in a number of advantages: The space savings due to lack of attachment points on the circuit breaker expand the possibilities for using other system components. The carrier plate allows e.g. the universal assembly of standard system components to be mounted on the front of the circuit-breaker, such as B. Kipphebelverriegelungen, Bowdenzugverriegelungen, Kipphebelblockiervorrichtungen, hand rotary drives or motor drives. The attachment of such circuit breaker accessories in the immediate vicinity of the circuit breaker (eg, the mounting of external accessories to a base plate on which the circuit breakers are mounted) is not necessary. Thus, the mounting of the circuit breaker accessories is much easier.

Es wurde eine Trägerplatte zum Tragen eines Leistungsschalter-Zubehörteils beschrieben, welche an zwei gegenüberliegenden Seitenwänden des Leistungsschalters montiert werden kann. Mittels dieser Trägerplatte können Leistungsschalter-Zubehörteile auf einfache und zuverlässige Art und Weise an dem Leistungsschalter montiert werden. Am Leistungsschalter selbst wird vorteilhafterweise insbesondere der Platz für die Befestigungsmittel der Leistungsschalter-Zubehörteile eingespart. A carrier plate for supporting a circuit breaker accessory which can be mounted on two opposite side walls of the circuit breaker has been described. By means of this carrier plate circuit breaker accessories can be easily and reliably mounted to the circuit breaker. The circuit breaker itself advantageously saves in particular the space for the fastening means of the circuit breaker accessories.
