Description
Die Neuerung bezieht sich auf Installationsuberstromschalter, bei denen die Ausschaltung bei Überstrom durch Durchdrücken eines gestreckten Kniehebels erfolgt. Dieser Schaltvorgang ist eine Momentschaltung, da der gestreckte Kniehebel unter dem Druck der Kontaktfeder steht, die bei dem Durchdrücken des Kniehebels plötzlich frei wird. Bei dem Ausschalten von Hand bleibt der ίο Kniehebel gestreckt; eine momentane Unterbrechung des Stromkreises tritt nicht ein. Die Erfindung zeigt nun eine Anordnung, bei der auch die Ausschaltbewegung durch Hand eine Momentschaltung ist. Solche Überstromschalter sind zwar schon bekannt. Die Erfindung zeigt aber eine besonders einfache Ausführungsform, die nachträglich ohne Schwierigkeiten an die bekannte Anordnung angebracht werden kann. Erfindungsgemäß gleitet der am Kniehebel angebrachte Auslösesporn nur bei der Einschaltbewegung an einem senkrecht zu dieser Bewegung federnd ausweichenden Glied vorbei, das sich in der Einschaltstellung vor den Auslösesporn setzt. Wird nun von Hand abgeschaltet, so bildet das federnde Glied einen festen Anschlag und verursacht das Durchdrücken des Kniehebels, so daß eine sofortige Abschaltung erfolgt.The innovation relates to installation overcurrent switches, which are switched off in the event of an overcurrent by pressing an extended toggle lever. This Switching is a momentary switching because the stretched knee lever is under the pressure the contact spring, which suddenly becomes free when the toggle lever is pushed through. When switching off by hand, the ίο knee lever remains stretched; a momentary interruption of the circuit does not occur. The invention now shows an arrangement in which the switch-off movement by hand is a momentary switching. Such overcurrent switches are already known. The invention but shows a particularly simple embodiment, which can subsequently be added to the known arrangement without difficulty can be attached. According to the invention, the trigger spur attached to the toggle lever slides only during the switch-on movement past a resiliently evasive member perpendicular to this movement, which is located in the Switch-on position before the trigger spur sets. If it is now switched off manually, it forms the resilient member makes a firm stop and causes the knee lever to be pushed through, so that an immediate shutdown takes place.
In den Abbildungen ist die Erfindung näher erläutert, und zwar zeigt Abb. ι die Seitenansicht eines Überstromschalters. In Abb. 2 ist diese Ansicht im Schnitt A, B dargestellt. α ist der Betätigungsgriff, der mittels des durchgedrückten Kniehebels b, c bei Einschalten den Kontakt d schließt. An dem Kniehebelarm b ist ein Sporn e angebracht, der bei Überstrom durch den Magnetanker / nach oben bewegt wird und dadurch den Kniehebel b, c durchdrückt, g sind zwei parallele Federstücke, deren Enden U-förmig nach innen gebogen sind und die bei der Einschaltbewegung von dem Sporn e zur Seite gedrückt werden, in der Einschaltstellung aber für den Sporn e einen Anschlag h bilden. Wird von Hand abgeschaltet, so stößt der Sporn e gegen diesen Anschlag h, der Kniehebel b, c drückt sich durch, und die Unterbrechung des Kontaktes d erfolgt augenblicklich.In the figures, the invention is explained in more detail, namely Fig. Ι shows the side view of an overcurrent switch. In Fig. 2 this view is shown in section A, B. α is the operating handle that closes contact d when the toggle lever b, c is pressed down. A spur e is attached to the toggle lever arm b, which is moved upwards by the magnet armature / in the event of an overcurrent and thereby pushes through the toggle lever b, c , g are two parallel spring pieces, the ends of which are bent inwards in a U-shape and which are activated during the switch-on movement be pushed to the side by the spur e , but in the switched-on position form a stop h for the spur e. If it is switched off manually, the spur e strikes this stop h, the toggle lever b, c pushes through, and the interruption of the contact d takes place immediately.
