Description

Die Erfindung betrifft einen Schaltmechanismus für Niederspannungsschaltgeräte gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a switching mechanism for low-voltage switching devices according to the preamble of claim 1.

Ein derartiger Schaltmechanismus zur Betätigung der elektrischen Kontakte eines Schaltgerätes ist bereits bekannt (DEP 35 08 110). Der dort beschriebene Schaltmechanismus weist ein Sperrglied auf, das die Aufgabe hat, die Schaltkontakte kurz vor der Berührung zunächst zu sperren. Das vorgespannte Sperrglied hält eine Schaltachse, die die übertragung zu den Schaltkontakten des Schaltgeräts herstellt, über eine Scheibe bis zu einer wählbaren Einschaltkraft am Schaltknebel. Mit dem Erhöhen der Einschaltkraft am Schaltknebel wird Energie durch elastische Verformung der Schaltglieder zwischen dem Schaltknebel und der Schaltachse gespeichert. Nach überwinden der Einschaltkraft wird das vorgespannte Sperrglied ausgelenkt und die Scheibe der Schaltachse rollt sich auf einer kreisförmigen Kontur des Sperrglieds ab. Mit entsprechender Auslenkung des vorgespannten Sperrglieds kommt die Scheibe aus dem Eingriff des Sperrglieds heraus und die Schaltachse schnellt in Einschaltrichtung und bewirkt somit ein sprunghaftes Einschalten der Schaltkontakte des Schaltgerätes.Such a switching mechanism for actuating the electrical contacts of a switching device is already known (DEP 35 08 110). The switching mechanism described there has a locking member, which has the task of locking the switching contacts shortly before touching them. The preloaded blocking element holds a switching axis, which establishes the transmission to the switching contacts of the switching device, via a disk up to a selectable switch-on force on the switching knob. With the increase of the switch-on force on the switching knob, energy is stored by elastic deformation of the switching elements between the switching knob and the switching axis. After the engagement force has been overcome, the prestressed locking member is deflected and the disk of the shifting axis rolls on a circular contour of the locking member. With a corresponding deflection of the pretensioned blocking element, the disk comes out of the engagement of the blocking element and the switching axis swings in the switching-on direction and thus causes the switching contacts of the switching device to switch on suddenly.

Es ist auch ein Schaltmechanismus zur Betätigung eines elektrischen Kontaktes eines Schaltgeräts beschrieben, der zum sprunghaften Einschalten der Schaltkontakte des Schaltgeräts eine Sprungeinschaltung aufweist. Es hat sich nun jedoch heraus gestellt, daß es in bestimmten Fällen nicht erforderlich ist, eine aufwendige Einrichtung zum sprunghaften Einschalten in einem derartigen Schaltgerät einzusetzen.A switching mechanism for actuating an electrical contact of a switching device is also described, which has a jump switch for the sudden switching on of the switching contacts of the switching device. It has now been found, however, that in certain cases it is not necessary to use a complex device for switching on suddenly in such a switching device.

Der Erfindung liegt nun die Aufgabe zugrunde, einen Schaltmechanismus für einen Fehlerstromschutzschalter zu entwickeln, der basierend auf einem leistungsfähigen Mechanismus durch Einsatz einfacher Teile preiswert herstellbar ist und ohne Sprungeinschaltung die technischen Anforderungen erfüllt.The invention is based on the object of developing a switching mechanism for a residual current circuit breaker which can be inexpensively produced based on a powerful mechanism by using simple parts and which fulfills the technical requirements without switching on.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebene Kombination von Merkmalen gelöst.This object is achieved by the combination of features specified in the characterizing part of claim 1.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß ein leistungsfähiger Schaltmechanismus durch Weglassen bzw. Ersatz einiger Teile für einfachere Anwendungen entstanden ist.The advantages achieved by the invention are that a powerful switching mechanism has been created by omitting or replacing some parts for simpler applications.

Ein Ausführungsbeispiel der Erfindung ist in einer Zeichnung dargestellt und wird im folgenden näher erläutert. Es zeigt die einzige Figur
einen Schaltmechanismus für einen Fehlerstromschutzschalter in Seitenansicht.An embodiment of the invention is shown in a drawing and is explained in more detail below. It shows the only figure
a switching mechanism for a residual current circuit breaker in side view.

Nach der Figur kann der Fehlerstromschutzschalter durch einen Schalthebel 4 von Hand ein- und ausgeschaltet werden. Hierzu ist der Schalthebel 4 mit einem Kniehebelsystem verbunden, das aus drei hebelartigen Laschen 1, 2 und 3 besteht. Das Kniehebelsystem besitzt ein gemeinsames Gelenk 5. Während die Lasche 1 mit dem Schalthebel 4 verbunden ist, steht die Lasche 2 mit einer Kontaktwelle 6 in Verbindung, auf welcher ein beweglicher Kontakt 8 befestigt ist. Dieser bewegliche Kontakt 8 korrespondiert mit einem festen Kontakt 9. Die Lasche 3, die gleichfalls mit dem Gelenk 5 verbunden ist, ist an ihrem freien Ende an einen Kipphebel 7 angelenkt.According to the figure, the residual current circuit breaker can be switched on and off manually by a switching lever 4 . For this purpose, the shift lever 4 is connected to a toggle lever system which consists of three lever-like tabs 1 , 2 and 3 . The toggle lever system has a common joint 5 . While the tab 1 is connected to the switching lever 4 , the tab 2 is connected to a contact shaft 6 , on which a movable contact 8 is attached. This movable contact 8 corresponds to a fixed contact 9 . The tab 3 , which is also connected to the joint 5 , is articulated at its free end to a rocker arm 7 .

Die Lasche 1 ist hierbei aus gestanztem Material hergestellt.The tab 1 is made of stamped material.
