Abstract

The invention relates to an interlocking device for mechanical switch-on blocking of one of two electromagnetic switching devices (12), which are arranged side-by-side, as long as the other switching device is in its switched-on position, the moving parts of the switching devices being capable of being coupled to blocking elements (4), preferably slides, emerging from the interlocking device. The moving parts of the switching devices are in this case the coupling parts for auxiliary switches which can be placed on the switching device, and the slides are matched to these coupling parts (10). In consequence, it is possible to fit an interlocking device for two electromagnetic switching devices which are arranged side-by-side instead of or as well as auxiliary switch blocks. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Verriegelungsvorrichtung zur mechanischen Einschaltsperrung eines von zwei nebeneinander angeordneten, elektromagnetischen Schaltgeräten, solange sich das andere Schaltgerät in seiner Einschaltstellung befindet, wobei die beweglichen Teile der Schaltgeräte mit von der Verriegelungsvorrichtung ausgehenden Sperrgliedern koppelbar sind.The invention relates to a locking device for mechanically switching off one of two electromagnetic switching devices arranged next to one another, as long as the other switching device is in its switched-on position, the movable parts of the switching devices being able to be coupled to locking members extending from the locking device.

Bei einer bekannten verrriegelungsvorrichtung der obengenannten Art (DE-OS 32 13 477) ist die Verriegelungsvorrichtung mit einer herzartigen, achslosen Wippe in einem Gehäuse versehen. Die Sperrglieder sind hier als stiftartige Teile ausgebildet, die sich senkrecht zur Bewegungsebene der Wippe und diametral voneinander in Richtung ihrer jeweils anzugliedernden Schaltgeräte erstrecken. Diese stiftartigen Teile sind in den vorgesehenen Wippenbewegungen angepaßten Ausnehmungen im Gehäuse kreisbogenförmig geführt. Die aus dem Gehäuse herausragenden Enden der stiftförmigen Teile werden durch die seitlichen Wände der Schaltgeräte in Nuten von Mitnehmergliedern eingeführt. Das Gehäuse der Verriegelungsvorrichtung wird hier mittels Schnapphaken, die in entsprechend angepaßte Ausnehmungen der Schaltgeräte einschnappen, mit den Schaltgeräten verbunden und an diesen gehalten.In a known locking device of the type mentioned above (DE-OS 32 13 477), the locking device is provided with a heart-like, axleless rocker in a housing. The locking members are designed here as pin-like parts that extend perpendicular to the plane of movement of the rocker and diametrically from each other in the direction of their respective switching devices to be attached. These pin-like parts are guided in a circular arc shape in the recesses provided in the provided rocker movements. The ends of the pin-shaped parts protruding from the housing are inserted through the side walls of the switchgear into grooves of driver links. The housing of the locking device is connected here by means of snap hooks which snap into correspondingly adapted recesses in the switching devices and held on the switching devices.

Der Erfindung liegt die Aufgabe zugrunde, eine Verriegelungsvorrichtung der obengenannten Art dahingehend zu verbessern, daß eine Ankopplung an elektromagnetische Schaltgeräte ohne besondere konstruktive, spezifische Ausbildung der Schaltgeräte möglich ist. Dies wird auf einfache Weise dadurch erreicht, daß die beweglichen Teile der Schaltgeräte die Kopplungsteile für auf das Schaltgerät aufsetzbare Hilfsschalter sind und die Sperrglieder diesen Kopplungsteilen angepaßt sind. Hierbei hat es sich als vorteilhaft erwiesen, wenn die Kopplungsteile hammerkopfartig ausgebildet sind und die Sperrglieder Schieber sind, deren freie Enden den Hammerkopf umgreifend auslaufen. Um auch bei der erfindungsgemäßen Verriegelungsvorrichtung die an sich bekannte Verriegelungswippe auf einfache Weise benutzen zu können ist es vorteilhaft, wenn die anderen Enden der Schieber formschlüssig mit einer Verriegelungswippe gekoppelt sind, deren Spitze sich im Sperrfall an einer Verriegelungskontur im Gehäuse der Verriegelungsvorrichtung abstützt. Um auch das Gehäuse der Verriegelungsvorrichtung auf einfache Weise mit den Gehäusen der Schaltgeräte koppeln zu können, ohne hierbei zusätzliche Maßnahmen ergreifen zu müssen, ist es von Vorteil, wenn das Gehäuse der Verriegelungsvorrichtung mit den Halterungsanformungen der Hilfsschalter angepaßten Anformungen versehen ist. Hierbei ist es von Vorteil, wenn die Sperrglieder im Raster der Kopplungsteile mit einem bestimmten Zuschlag angebracht sind. Ist zwischen zwei Sperrgliedern Raum für ein weiteres Kopplungsteil freigelassen, so ist es möglich, beispielsweise bei einem vierpoligen Schütz, auf dem vier einzelne Hilfsschaltereinheiten aufgeschnappt werden können, auf der einen Seite zwei Plätze für Einzelhilfsschalter mit der Verriegelungsvorrichtung zu belegen und auf der anderen Seite lediglich einen, so daß auf dem einen Schütz zwei Hilfsschalterplätze und auf dem anderen drei Hilfsschalterplätze oder umgekehrt zur Verfügung stehen. Sollen bei beiden Schützen drei Hilfsschalterplätze freibleiben, so ist es lediglich erforderlich, die beiden elektromagnetischen Schaltgeräte im Abstand des Rasters voneinander auf der Normschiene zu befestigen. Es ist hierdurch beispielsweise auch möglich, die Verriegelungsvorrichtung bei elektromagnetischen Schaltgeräten größerer Bauart zu benutzen, wenn der Abstand der ersten Hilfsschalteranordnung vom Rand der Schaltgeräte größer als bei kleineren Schützen ausgebildet ist. Um ein Lösen der Verriegelungsvorrichtung von den Schaltgeräten im aufgesetzten Zustand zu verhindern, ist es von Vorteil, wenn die Verriegelungsvorrichtung quer zur Bewegungsrichtung der beweglichen Teile der Schaltgeräte auf diese aufschiebbar und koppelbar ist und daß zumindest ein Schieber zur lösbaren Verrastung der Verriegelungsvorrichtung an den Schaltgeräten vorgesehen ist. Hier kann vorteilhafterweise ein gemeinsamer Schieber zur Kopplung mit festen Teilen der Schaltgeräte vorhanden sein.The invention has for its object to improve a locking device of the type mentioned above so that coupling to electromagnetic switching devices is possible without special constructive, specific training of the switching devices. This is achieved in a simple manner in that the movable parts of the switching devices are the coupling parts for auxiliary switches that can be placed on the switching device and the blocking elements of these coupling parts are adjusted. It has proven to be advantageous if the coupling parts are designed like hammer heads and the locking members are slides, the free ends of which run around the hammer head. In order to be able to use the known locking rocker in a simple manner in the locking device according to the invention, it is advantageous if the other ends of the slide are positively coupled to a locking rocker, the tip of which is supported on a locking contour in the housing of the locking device in the event of a lock. In order to be able to couple the housing of the locking device to the housings of the switching devices in a simple manner without having to take any additional measures, it is advantageous if the housing of the locking device is provided with the molded parts adapted to the mounting of the auxiliary switches. It is advantageous here if the locking members are attached in the grid of the coupling parts with a certain surcharge. If there is space for a further coupling part between two blocking elements, it is possible, for example in the case of a four-pole contactor on which four individual auxiliary switch units can be snapped on, to occupy two places for individual auxiliary switches with the locking device and on the other hand only one so that two auxiliary switch positions are available on one contactor and three auxiliary switch positions on the other or vice versa. If three auxiliary switch positions are to remain free with both contactors, it is only necessary to fasten the two electromagnetic switching devices on the standard rail at a spacing of the grid from one another. It is hereby also possible, for example, to use the locking device in electromagnetic switching devices of a larger design if the distance of the first auxiliary switch arrangement from the edge of the switching devices is greater than that of smaller contactors. In order to prevent the locking device from being released from the switching devices in the attached state, it is advantageous if the locking device is applied to the moving parts of the switching devices transversely to the direction of movement can be pushed on and coupled and that at least one slide is provided for releasably latching the locking device on the switching devices. A common slide for coupling with fixed parts of the switching devices can advantageously be present here.

An exemplary embodiment according to the invention is described with reference to the drawing. Show it:

FIG 6
a possibility of applying the locking device to two electromagnetic switching devices of an even larger series.

Die Verriegerungsvorrichtung gemäß der Erfindung besteht aus dem Gehäuse 1, in dem eine über eine Feder 2 federbelastete Wippe 3 entgegen der Bewegungseinschaltrichtung von Sperrgliedern 4 federbelastet ist. Die Sperrglieder 4 sind über an die Wippe 3 angeformte Zapfen 5, die in Ausnehmungen 6 der Sperrglieder 4 hineinragen, mehr oder weniger formschlüssig gekoppelt. Die Sperrglieder 4 sind als Sperrschieber verschiebbar im Gehäuse 1 geführt. Die Wippe ist dreieckförmig ausgebildet und gleitet bei der Abwärtsbewegung eines der Sperrschieber mit der Dreieckspitze 7 in geringem Abstand an entsprechend geformten Flächen 8 des Gehäuses 1 vorbei, so daß die Abwärtsbewegung des anderen Sperrschiebers 4 verhindert ist. Dieses Gerät kann nicht einschalten. Die Sperrschieber 4 sind weiterhin mit rechteckförmigen Öffnungen 9 ausgestattet, die zur freien Seite hin offen sind, so daß ein Hammerkopf 10 weitgehend formschlüssig eingeschoben werden kann, der am Kontaktbrückenträger 11 eines elektromagnetischen Schaltgerätes 12 angeformt ist. Derartige Kopplungsanordnungen sind beispielsweise durch das DE-GM 88 05 878 bekanntgeworden. Dem Hammerkopf 10 angepaßt ist eine hammerkopfförmige Anformung 13 am Gehäuse des elektromagnetischen Schaltgerätes 12, die mit entsprechenden Vorsprüngen 14 am Gehäuse 1 der Verriegelungsvorrichtung zusammenwirken. Zwei hakenförmige Ansätze 15 am Gehäuse 1 der Verriegelungsvorrichtung greifen beim Verschieben der Verriegelungsvorrichtung in die Betriebsstellung in eine entsprechend ausgeformte Vertiefung 16 ein, so daß das Gehäuse 1 an drei Punkten fest mit dem Gehäuse des elektromagnetischen Schaltgerätes 12 verbunden ist. Um das Zurückschieben der Verriegelungsvorrichtung zu verhindern, ist ein Schieber 20 zur lösbaren Verrastung vorgesehen. Der Schieber 20 ist entgegen der Kraft einer Feder 17 oder federnder Kunststoffzungen zur Freigabe der hammerkopfförmigen Anformung verschiebbar. Eine schräge Fläche 18 drängt beim Aufsetzen der Verriegelungsvorrichtung den Schieber 20 entgegen der Kraft der Feder zurück, bis er hinter der hammerkopfförmigen Anformung 13 verrastet. Eine in der Mitte zwischen den beiden Sperrgliedern 4, die im Ausführungsbeispiel als Schieber ausgebildet sind, vorgesehene Ausformung 19 im Gehäuse 1 ist im Rastermaß für den Abstand der Einzelhilfsschalterplätze, wie sie aus den FIG 3 - 6 zu entnehmen ist, angeordnet. Hierdurch ergibt sich die Möglichkeit, die Verriegelungsvorrichtung auf zwei elektromagnetische Schaltgeräte 12 in den aus FIG 3 bis 6 ersichtlichen Möglichkeiten aufzubringen. Bei der FIG 3 ist im linken Schütz das Aufsetzen von zwei Hilfsschalterblöcken und im rechten Schütz das Aufsetzen von drei Hilfsschalterblöcken möglich, wobei beide elektromagnetische Schaltgeräte 12 bis auf einen geringen Abstand ziemlich dicht aneinanderliegen. Sollen jedoch auf beiden Schützen drei Hilfsschalterblöcke aufgebracht werden, so kann dies gemäß FIG 4 dadurch erfolgen, daß beide elektromagnetischen Schaltgeräte 12 in einem gewissen Abstand zueinander auf der Normtragschiene befestigt werden. Der gleiche Sachverhalt trifft für eine etwas größere Baureihe von elektromagnetischen Schaltgeräten zu, wie sie FIG 5 darstellt. Hier ist bei der Anordnung gemäß FIG 3 kein Abstand zwischen den beiden Schaltgeräten 12 mehr vorhanden. Bei der Ausführungsform nach FIG 6 ist die Verriegelungsvorrichtung bei Schützen 12 anwendbar, die einer größeren Baureihe angehören. Die Einzelhilfsschalterblöcke sitzen hier weiter entfernt vom Rand der Schaltgeräte, so daß hier immer ein Aufsetzen dreier Hilfsschalterblöcke auf beide elektromagnetischen Schaltgeräte möglich ist.The locking device according to the invention consists of the housing 1, in which a rocker 3, which is spring-loaded via a spring 2, is spring-loaded against the movement switching direction of locking members 4. The locking members 4 are more or less positively coupled via pins 5 formed on the rocker 3, which protrude into recesses 6 of the locking members 4. The locking members 4 are slidably guided in the housing 1 as a locking slide. The rocker is triangular in shape and slides past one of the locking slides with the triangular tip 7 at a short distance from correspondingly shaped surfaces 8 of the housing 1, so that the downward movement of the other locking slide 4 is prevented. This device cannot turn on. The locking slide 4 are further equipped with rectangular openings 9 which are open to the free side, so that a hammer head 10 can be largely inserted in a form-fitting manner, which is integrally formed on the contact bridge support 11 of an electromagnetic switching device 12. Coupling arrangements of this type have become known, for example, from DE-GM 88 05 878. The hammer head 10 is adapted to a hammer head-shaped projection 13 on the housing of the electromagnetic switching device 12, which cooperate with corresponding projections 14 on the housing 1 of the locking device. Two hook-shaped lugs 15 on the housing 1 of the locking device engage when the locking device is moved into the operating position in a correspondingly shaped recess 16, so that the housing 1 is firmly connected to the housing of the electromagnetic switching device 12 at three points. In order to prevent the locking device from being pushed back, a slide 20 is provided for releasable locking. The slide 20 is displaceable against the force of a spring 17 or resilient plastic tongues to release the hammer head-shaped formation. An inclined surface 18 pushes the slide 20 back against the force of the spring when the locking device is placed on it, until it locks behind the hammer head-shaped projection 13. One in the middle between the two Locking members 4, which in the exemplary embodiment are designed as slides, the molded shape 19 provided in the housing 1 is arranged in the grid dimension for the spacing of the individual auxiliary switch locations, as can be seen from FIGS. 3-6. This results in the possibility of applying the locking device to two electromagnetic switching devices 12 in the ways shown in FIGS. 3 to 6. In FIG. 3, it is possible to place two auxiliary switch blocks in the left contactor and three auxiliary switch blocks in the right contactor, both electromagnetic switching devices 12 being quite close to one another apart from a short distance. However, if three auxiliary switch blocks are to be applied to both contactors, this can be done according to FIG. 4 in that both electromagnetic switching devices 12 are attached to the standard mounting rail at a certain distance from one another. The same situation applies to a somewhat larger series of electromagnetic switching devices, as shown in FIG. 5. In the arrangement according to FIG. 3, there is no longer any distance between the two switching devices 12. In the embodiment according to FIG. 6, the locking device can be used with shooters 12 who belong to a larger series. The individual auxiliary switch blocks are located further away from the edge of the switching devices, so that it is always possible to place three auxiliary switch blocks on both electromagnetic switching devices.
