Description

Die Erfindung betrifft ein elektrisches Gerät, insbesondere einen Schutzschalter, mit einem Schaltschloss mit einem, insbesondere verschiebbar oder verschwenkbar gelagerten, Betätigungsknopf, der mit beweglichen Kontakten eines Kontaktapparates kuppelbar ist, mit einer mit dem Betätigungsknopf gekuppelten, bewegbar gelagerten Klinke, der eine im Schaltschloss bewegbar gelagerte Klinkenauflage zugeordnet ist, welcher das Auslöseelement eines Auslösers zugeordnet ist.The invention relates to an electrical device, in particular a circuit breaker, with a switch lock with a, in particular slidably mounted or pivotally mounted, operating button which can be coupled with movable contacts of a contact device, with a coupled to the operating knob, movably mounted pawl, which moves in a switch latch is associated with stored latch support, which is associated with the trigger element of a trigger.

Ein elektrisches Gerät der genannten Art ist aus der AT 404 771 B bekannt, welche einen Schutzschalter betrifft. Im Zuge von elektrischen Servicearbeiten werden üblicherweise betroffene Stromkreise mittels eines Schutzschalters ausgeschaltet. Nachteilig ist jedoch, dass ein Stromkreis mittels eines Schutzschalters wieder aktiviert werden kann, bevor die Servicearbeiten abgeschlossen sind und so das Montagepersonal gefährdet werden würde. Diese Gefahr ist insbesondere dann gegeben, wenn die Servicearbeiten nicht in unmittelbarer räumlicher Nähe zum Schutzschalter durchgeführt werden und ein Betätigen des Schutzschalters vom Montagepersonal unbemerkt bliebe und weiters wenn parallel Servicearbeiten unterschiedlicher Art von unterschiedlichen Personen oder Personengruppen durchgeführt werden.An electrical device of the type mentioned is from the AT 404 771 B known, which relates to a circuit breaker. In the course of electrical service work normally affected circuits are switched off by means of a circuit breaker. The disadvantage, however, is that a circuit can be reactivated by means of a circuit breaker before the service work is completed and so the assembly personnel would be at risk. This danger is especially true if the service work is not carried out in the immediate vicinity of the circuit breaker and operation of the circuit breaker unnoticed by the installation staff and further if parallel service work of different types of different people or groups of people are performed.

Es ist daher Aufgabe vorliegender Erfindung, die bekannten Nachteile zu vermeiden und zu gewährleisten, dass ein Schutzschalter nicht unbemerkt, unbeabsichtigt oder unbefugt eingeschaltet werden kann und gegen Wiedereinschalten gesichert wird.It is therefore an object of the present invention to avoid the known disadvantages and to ensure that a circuit breaker can not be turned on unnoticed, unintentionally or without authorization and is secured against reconnection.

Erfindungsgemäß wird dies dadurch erreicht, dass die Bewegbarkeit der Klinkenauflage durch ein willkürlich betätigbares Arretierungselement blockierbar ist.According to the invention this is achieved in that the mobility of the latch support is blockable by an arbitrarily actuated locking element.

Dadurch ergibt sich der Vorteil, dass die Klinkenauflage außer Eingriff der Klinke gebracht und arretiert wird, wodurch eine Aktivierung des Schutzschalters durch Dritte sicher unterbunden werden kann. So kann die Sicherheit von Montagepersonal und anderen Personen erhöht werden.This results in the advantage that the latch support is disengaged from the latch and locked, whereby activation of the circuit breaker can be safely prevented by third parties. Thus, the safety of assembly personnel and other people can be increased.

In weiterer Ausbildung der Erfindung kann vorgesehen sein, dass die Klinke verschwenkbar gelagert ist und/oder die Klinkenauflage im Schaltschloss verschwenkbar gelagert ist. Eine verschwenkbare Lagerung der Klinke und/oder der Klinkenauflage kann besonders einfach und kostengünstig hergestellt werden.In a further embodiment of the invention can be provided that the pawl is pivotally mounted and / or the latch support is pivotally mounted in the switch lock. A pivotable mounting of the pawl and / or the pawl support can be made particularly simple and inexpensive.

Der Einsatz eines Permanentmagnetauslösers und/oder eines Auslösestössels ist für ein sicheres Auslösen eines elektrischen Gerätes, insbesondere eines Schutzschalters, besonders gut geeignet.The use of a permanent magnet release and / or a trip rod is particularly well suited for a safe triggering of an electrical device, in particular a circuit breaker.

Eine Variante der Erfindung kann darin bestehen, dass die Klinkenauflage federbelastet ist. Durch die Feder wird die Klinkenauflage in jener Stellung gehalten, die für den Eingriff der Klinke und der Klinkenauflage erforderlich ist, sofeme der Auslöser oder das Arretierungselement nicht aktiviert ist, wodurch die zuverlässige Funktion des Schaltschlosses gewährleistet ist.A variant of the invention may consist in that the latch support is spring-loaded. By the spring, the latch support is held in that position, which is required for the engagement of the pawl and the pawl support, sofeme the trigger or the locking element is not activated, whereby the reliable operation of the switching mechanism is ensured.

In Weiterbildung der Erfindung kann vorgesehen sein, dass die beweglichen Kontakte mit dem Betätigungsknopf unmittelbar kuppelbar sind. Dadurch wird eine besonders zuverlässige Kupplung sichergestellt.In a further development of the invention can be provided that the movable contacts with the operating knob are directly coupled. This ensures a particularly reliable coupling.

Gemäß einer weiteren Ausführungsform der Erfindung kann vorgesehen sein, dass das Arretierungselement durch einen im Gerät bewegbar gelagerten, zweiarmigen Hebel gebildet ist, dessen eines Ende der Klinkenauflage zugeordnet ist und über dessen anderes Ende der Hebel willkürlich betätigbar ist. Diese Ausbildung der Erfindung ist besonders einfach herzustellen und ermöglicht auch eine einfache und sichere Betätigung derselben.According to a further embodiment of the invention can be provided that the locking element is formed by a movably mounted in the device, two-armed lever, one end of the latch support is assigned and the other end of the lever is arbitrarily actuated. This embodiment of the invention is particularly easy to manufacture and also allows easy and safe operation of the same.

Eine andere Variante der Erfindung kann darin bestehen, dass das Arretierungselement verschiebbar, insbesondere längs seiner eigenen Achse verschiebbar, ausgebildet ist. So kann die Öffnung, durch die das Arretierungselement ins Freie geführt wird, minimal gehalten werden, was einen besseren Schutz des elektrischen Geräts von schädlichen Umwelteinflüssen wie Staub oder Feuchtigkeit bedeutet.Another variant of the invention may consist in that the locking element is displaceable, in particular displaceable along its own axis, is formed. Thus, the opening through which the locking element is led into the open, be kept minimal, which means better protection of the electrical device from harmful environmental influences such as dust or moisture.

Eine Variante der Erfindung kann darin bestehen, dass das Arretierungselement im wesentlichen parallel zu einer Schlossplatte verschwenkbar ist. Eine solche Anordnung ermöglicht einen besonders platzsparenden Einbau des Arretierungselements.A variant of the invention may consist in that the locking element is pivotable substantially parallel to a lock plate. Such an arrangement allows a particularly space-saving installation of the locking element.

Gemäß einer weiteren Ausbildung der Erfindung kann vorgesehen sein, dass das eine Ende des Arretierungselements mit einem dem Auslöseelement des Auslösers zugeordneten, die Schlossplatte über einen Schlitz durchsetzenden Ansatz der Klinkenauflage in Anlage bringbar ist. Damit kann durch das Arrertierungselement die Funktion des Auslösers simuliert werden.According to a further embodiment of the invention can be provided that the one end of the locking element associated with a release element of the trigger, the lock plate passing through a slot approach the latch support is brought into contact. This can be simulated by the Arrertierungselement the function of the shutter.

Damit kann die jeweilige Schaltposition des Arretierungselements genau definiert werden und eine Fehlbetätigung erschwert werden.In continuation of the invention can be provided that the other end of the locking element along a catch bar is adjustable. Thus, the respective switching position of the locking element can be precisely defined and a mishandling be difficult.

In diesem Zusammenhang kann in Weiterbildung der Erfindung vorgesehen sein, dass das andere Ende des Arretierungselements in einem aus dem Gerät herausgeführten Teil mit wenigstens einer Durchbrechung, vorzugsweise für die Aufnahme von Feststellplomben, ausgebildet ist. So kann eine unbefugte oder unbeabsichtigte Betätigung des Arretierungselementes zuverlässig verhindert werden.In this context, it can be provided in a further development of the invention that the other end of the locking element in a led out of the device part with at least one opening, preferably for the reception of locking seals, is formed. Thus, unauthorized or unintentional actuation of the locking element can be reliably prevented.

In Weiterbildung der Erfindung kann vorgesehen sein, dass das Arretierungselement über ein weiteres Betätigungselement betätigbar ist. Auf diese Art kann ein Arretierungselement auch bei nur schwer zugänglicher Konstruktion betätigbar realisiert werden.In a further development of the invention it can be provided that the locking element can be actuated via a further actuating element.

This pawl 6 is associated with a pivotally mounted latch support 7, wherein it is provided that in the working position of the electrical switch 1, the pawl 6 rests on the support surface 13 of the latch support 7 and engages. The support surface 13 opposite the end of the latch support 7, the lug 17, the trigger element 8 of a Trigger 9 associated, both in Fig. 3 are shown. The latch support 7 is arranged blockable by an arbitrarily actuable locking element 10.

Eines oder mehrere der Elemente Betätigungsknopf 3, Klinke 6 oder Klinkenauflage 7, können auch translatorisch verschiebbar gelagert sein, wobei es nicht erfindungswesentlich ist, wieviele oder welche dieser Elemente in welcher Art und Kombination bewegbar gelagert sind. Der Auslöser 9 ist als Permanentmagnetauslöser und das Auslöseelement 8 als Auslösestössel des Permanentmagnetauslösers dargestellt, aber auch andere Arten von Auslösern, wie z.B. Bimetallauslöser, Spulen mit Anker oder dgl. können Bestandteil des elektrischen Geräts 1 sein.One or more of the elements actuating button 3, pawl 6 or pawl support 7, can also be mounted translationally displaceable, wherein it is not essential to the invention, how many or which of these elements are movably mounted in what kind and combination. The trigger 9 is shown as a permanent magnet release and the trigger element 8 as a trigger ram of the permanent magnet release, but also other types of triggers, e.g. Bimetallic releases, coils with anchor or the like. May be part of the electrical device 1.

Im Falle der Aktivierung des Auslösers 9, beispielsweise durch Erreichung einer vorgegebenen Spannung, drückt das Auslöseelement 8 gegen den Ansatz 17 der Klinkenauflage 7, die dadurch derart gegen die Kraft einer Feder 20 bewegt wird, dass die Klinke 6 außer Eingriff der Klinkenauflage 7 gerät und so in an sich bekannter Weise den elektrischen Schalter 1 in Ruhestellung verbringt. Es kann weiters ein Rücksteller 16 vorgesehen sein, der nach der Aktivierung des Auslösers 9 das Auslöseelement 8 durch Federwirkung wieder in die Ausgangsstellung verbringt.In the case of activation of the trigger 9, for example, by reaching a predetermined voltage, the trigger element 8 presses against the lug 17 of the pawl 7, which is thereby moved against the force of a spring 20, that the pawl 6 disengages the pawl rest 7 and so in a conventional manner the electrical switch 1 spends at rest. It can also be provided a reset 16, which spends after the activation of the trigger 9, the trigger element 8 by spring action back into the starting position.
