Description

Beschreibungdescription
Elektromagnetisches Schaltgerät, insbesondere Schütz, mit einer KontaktbrückenträgerverriegelungElectromagnetic switching device, in particular a contactor, with a contact bridge support lock
Die vorliegende Erfindung betrifft ein elektromagnetisches Schaltgerät, insbesondere ein Schütz, mit einem Unterteil, einer vom Unterteil abnehmbaren Lichtbogenkammer, einem Kontaktbruckentrager und einem federbelasteten Sperrelement, wo- bei der Kontaktbruckentrager im Unterteil gehalten ist, in die Lichtbogenkammer hineinragt und in einer Betätigungsrichtung verschiebbar ist, wobei der Kontaktbruckentrager bei abgenommener Lichtbogenkammer mittels des Sperrelements verriegelbar ist, wobei das Sperrelement im Unterteil gehalten ist und als um eine Schwenkachse schwenkbarer Hebel ausgebildet ist .The present invention relates to an electromagnetic switching device, in particular a contactor, with a lower part, an arc chamber which can be removed from the lower part, a contact bridge support and a spring-loaded blocking element, the contact bridge support being held in the lower part, projecting into the arc chamber and being displaceable in an actuation direction, wherein the contact bridge support can be locked by means of the locking element when the arc chamber is removed, the locking element being held in the lower part and being designed as a lever which can be pivoted about a pivot axis.
Ein derartiges Schaltgerät ist beispielsweise aus der DE 43 41 330 Cl bekannt. Das bekannte Schaltgerät arbeitet bereits recht gut, das Sperrelement benötigt aber relativ viel Bauraum.Such a switching device is known for example from DE 43 41 330 Cl. The known switching device already works quite well, but the locking element requires a relatively large amount of space.
Aus der DE 34 02 836 AI ist ein ähnliches elektromagnetisches Schaltgerät bekannt. Bei diesem Schaltgerät ist das Sperrele- ment im Kontaktbruckentrager gelagert.A similar electromagnetic switching device is known from DE 34 02 836 AI. In this switching device, the locking element is mounted in the contact bridge support.
Aus der DE 195 47 011 Cl ist ein elektromechanisches Schaltgerät bekannt, bei dem der Kontaktbruckentrager mittels eines schwenkbaren Hebels in seiner eingeschalteten Stellung ver- riegelbar ist, wobei der Hebel um ein Schwenkachse schwenkbar ist, welche senkrecht zur Betätigungsrichtung des Kontaktbrückenträgers verläuft.From DE 195 47 011 Cl an electromechanical switching device is known in which the contact bridge support can be locked in its switched-on position by means of a pivotable lever, the lever being pivotable about a pivot axis which runs perpendicular to the direction of actuation of the contact bridge support.
Die Aufgabe der vorliegenden Erfindung besteht darin, ein Schaltgerät derart weiterzuentwickeln, daß es kompakter aufgebaut ist. Die Aufgabe wird dadurch gelöst, daß die Schwenkachse senkrecht zur Betätigungsrichtung verläuft .The object of the present invention is to further develop a switching device in such a way that it is more compact. The object is achieved in that the pivot axis is perpendicular to the direction of actuation.
Wenn das Schwenkelement beim Schwenken in einer Pfannenlage- rung geführt wird, ist die Lagerung des Sperrelements besonders einfach.If the swivel element is guided in a pan position when swiveling, the storage of the locking element is particularly simple.
Wenn das Sperrelement unverlierbar im Unterteil gehalten ist, ist das Schaltgerät besonders betriebssicher. Die unverlier- bare Halterung kann z. B. dadurch bewirkt werden, daß dasIf the locking element is held captively in the lower part, the switching device is particularly reliable. The captive bracket can e.g. B. caused by that
Sperrelement und das Unterteil zum Halten des Sperrelements im Unterteil zusammenwirkende Rastelemente aufweisen, wobei mindestens eines der Rastelemente in Richtung der Schwenkachse federnd auslenkbar ist.Have locking element and the lower part cooperating locking elements for holding the locking element in the lower part, wherein at least one of the locking elements is resiliently deflectable in the direction of the pivot axis.
Wenn das Sperrelement mit dem Kontaktbruckentrager in einem Riegelbereich zusammenwirkt und im Riegelbereich eine Anlaufschräge aufweist, ist der Kontaktbruckentrager frei gestaltbar, ohne daß die Gefahr eines unerwünschten Hängenbleibens vor Erreichen der Verriegelungsstellung besteht.If the locking element interacts with the contact bridge support in a locking area and has a run-up slope in the locking area, the contact bridge support can be freely designed without the risk of undesired getting caught before reaching the locking position.
Wenn das Sperrelement bei abgenommener Lichtbogenkammer manuell zugänglich und manuell betätigbar ist, ist ein Test des Schaltgeräts auf ordnungsgemäßes Funktionieren besonders ein- fach durchführbar.If the blocking element is manually accessible and manually operable when the arc chamber is removed, it is particularly easy to test the switching device for proper functioning.
Der Test wird noch einfacher, wenn das Schaltgerät außer dem Sperrelement kein weiteres Sperrelement zum Verriegeln des Kontaktbrückenträgers aufweist.The test is made even easier if the switching device has no other locking element for locking the contact bridge support apart from the locking element.
Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels . Dabei zeigen in PrinzipdarstellungFurther advantages and details emerge from the following description of an exemplary embodiment. Show in principle
FIG 1 ein Schütz,1 shows a contactor,
FIG 2 einen Ausschnitt von FIG 1 und FIG 3 ein Sperrelement . Gemäß FIG 1 weist ein Schütz als Beispiel eines elektromagnetischen Schaltgeräts ein Unterteil 1 und eine Lichtbogenkammer 2 auf. Die Lichtbogenkammer 2 ist, wie in FIG 1 durch einen Pfeil A angedeutet, vom Unterteil 1 abnehmbar.2 shows a section of FIG. 1 and FIG. 3 shows a locking element. According to FIG. 1, a contactor has a lower part 1 and an arc chamber 2 as an example of an electromagnetic switching device. The arc chamber 2, as indicated by an arrow A in FIG. 1, can be removed from the lower part 1.
Im Unterteil 1 ist eine Antriebsspule 3 angeordnet. Durch Beaufschlagen der Antriebsspule 3 mit einem Schaltstrom wird ein Kontaktbruckentrager 4 in einer Betätigungsrichtung x verschoben. Der Kontaktbruckentrager 4 ist im Unterteil 1 ge- lagert und ragt in die Lichtbogenkammer 2 hinein.A drive coil 3 is arranged in the lower part 1. By applying a switching current to the drive coil 3, a contact bridge support 4 is displaced in an actuation direction x. The contact bridge support 4 is mounted in the lower part 1 and projects into the arc chamber 2.
Gemäß FIG 2 weist das Schütz ferner ein Sperrelement 5 auf, das mittels einer Feder 6 federbelastet ist. Gemäß FIG 2 ist die Feder 6 als Druckfeder ausgebildet. Prinzipiell könnte die Feder 6 aber auch als Zug- oder Drehfeder ausgebildet sein.According to FIG. 2, the contactor also has a blocking element 5 which is spring-loaded by means of a spring 6. According to FIG 2, the spring 6 is designed as a compression spring. In principle, the spring 6 could also be designed as a tension or torsion spring.
Mittels des Sperrelements 5 ist der Kontaktbruckentrager 4 bei abgenommener Lichtbogenkammer 2 in der ausgeschalteten Stellung des Schützes verriegelbar. Hierzu wirkt das Sperrelement 5 mit dem Kontaktbruckentrager 4 in einem Riegelbereich 7 zusammen. Der Riegelbereich 7 ist hakenförmig ausgebildet und weist an seinem unteren Ende eine Anlaufschräge 8 auf . Mit seinem hakenförmigen Riegelbereich 7 greift das Sperrelement 5 in eine entsprechende Gegenkontur 9 des Kontaktbrückenträgers 4 ein und verriegelt dadurch den Kontaktbruckentrager 4.By means of the blocking element 5, the contact bridge support 4 can be locked in the switched-off position of the contactor when the arc chamber 2 is removed. For this purpose, the locking element 5 cooperates with the contact bridge support 4 in a locking area 7. The locking area 7 is hook-shaped and has a run-on slope 8 at its lower end. With its hook-shaped locking area 7, the blocking element 5 engages in a corresponding counter contour 9 of the contact bridge support 4 and thereby locks the contact bridge support 4.
Gemäß FIG 2 ist das Sperrelement 5 als Hebel ausgebildet, der um eine Schwenkachse 10 schwenkbar ist. Die Schwenkachse 10 verläuft dabei senkrecht zur Betätigungsrichtung x. Es weist eine halbkreisförmige Lagerstelle 11 auf, die in einer korrespondierenden Lagerpfanne des Unterteils 1 lagerbar ist. Das Sperrelement 5 wird dadurch beim Schwenken in einer Pfan- nenlagerung 11 geführt. Gemäß FIG 3 weist das Sperrelement 5 ferner ein Rastelement 12 auf. Das Rastelement 12 ist in Richtung der Schwenkachse 10 federnd auslenkbar. Das Rastelement 12 wirkt mit einem weiteren Rastelement zusammen, das im Unterteil 1 angeordnet ist. Das weitere Rastelement kann, muß aber nicht in Richtung der Schwenkachse 10 federnd auslenkbar sein. Durch das Zusammenwirken der Rastelemente 12 ist das Sperrelement 5 unverlierbar im Unterteil 1 gehalten.According to FIG 2, the locking element 5 is designed as a lever which is pivotable about a pivot axis 10. The pivot axis 10 extends perpendicular to the actuation direction x. It has a semicircular bearing point 11 which can be stored in a corresponding bearing pan of the lower part 1. The locking element 5 is thereby guided when pivoting in a pan bearing 11. According to FIG 3, the locking element 5 also has a locking element 12. The locking element 12 can be deflected resiliently in the direction of the pivot axis 10. The locking element 12 cooperates with a further locking element which is arranged in the lower part 1. The further latching element can, but need not, be deflectable in the direction of the pivot axis 10. Due to the interaction of the locking elements 12, the locking element 5 is held captively in the lower part 1.
Auch das Rastelement 12 weist eine Anlaufschräge 13 auf. Das Einsetzen des Sperrelements 5 in das Unterteil 1 kann somit durch einfaches Einschieben in das Unterteil 1 in Einschubrichtung y erfolgen.The locking element 12 also has a run-on slope 13. The locking element 5 can thus be inserted into the lower part 1 by simply pushing it into the lower part 1 in the insertion direction y.
Beim Aufsetzen der Lichtbogenkammer 2 auf das Unterteil 1 erfolgt zwangsweise und automatisch ein Entriegeln des Kontaktbrückenträgers 4. Wie in FIG 2 durch einen Finger 14 schematisch angedeutet ist, ist das Sperrelement 5 bei abgenommener Lichtbogenkammer 2 aber auch manuell zugänglich und manuell betätigbar. Es ist daher möglich, den Kontaktbruckentrager 4 bei abgenommener Lichtbogenkammer 2 zu entriegeln und dann das Schütz auf ordnungsgemäße Funktion zu testen. Aufgrund der Anlaufschräge 8 kann es dabei beim Rücküberführen des Kontaktbrückenträgers 4 in die ausgeschaltete Stellung des Schützes nicht geschehen, daß der Kontaktbruckentrager 4 vor Erreichen der Ausstellung sich mit dem Sperrelement 5 verhakt.When the arc chamber 2 is placed on the lower part 1, the contact bridge carrier 4 is forcibly and automatically unlocked. As indicated schematically in FIG. 2 by a finger 14, the blocking element 5 is also manually accessible and manually operable when the arc chamber 2 is removed. It is therefore possible to unlock the contact bridge support 4 with the arc chamber 2 removed and then to test the contactor for proper function. Because of the run-up slope 8, when the contact bridge carrier 4 is returned to the switched-off position of the contactor, it cannot happen that the contact bridge carrier 4 hooks with the blocking element 5 before reaching the exhibition.
Prinzipiell ist es möglich, mehrere (insbesondere symmetrisch verteilt angeordnete) Sperrelemente 5 vorzusehen. Besonders der Test bei abgenommener Lichtbogenkammer 2 ist aber besonders einfach, wenn das Schütz nur ein einziges Sperrelement 5, also zum Verriegeln des Kontaktbrückenträgers 4 kein weiteres Sperrelement, aufweist. In principle, it is possible to provide several (in particular arranged symmetrically distributed) locking elements 5. In particular, the test with the arc chamber 2 removed is particularly simple if the contactor has only a single blocking element 5, that is to say no further blocking element for locking the contact bridge carrier 4.
