Description

Die aus Gründen der Raumersparnis vielfach bevorzugten sogenannten Schubtrennschalter weisen in den bisher bekannten Ausführungen verschiedene Mangel auf. Die Eigenart der Messerführung bringt es mit sich, daß bei diesen Schubtrennschaltern an der Kontaktstelle, in der das Messer gleitet, entweder zu große Übergangswiderstände entstehen oder daß der Aufwand an MaterialThe so-called push disconnectors, which are often preferred for reasons of space saving have various deficiencies in the previously known designs. It has the peculiarity of the knife guide that with these sliding disconnectors at the contact point in which the knife slides, either too large contact resistances arise or that the cost of material

to ein unverhältnismäßig großer ist. Es sind z. B. Messerführungen bekannt, bei denen das Schaltmesser einen Führungsschlitz entweder in der Mitte oder an der unteren Kante aufweist. Besonders bei Schaltern höherer Stromstärken ist diese Art der Konstruktion unpraktisch, da die Gefahr der Erwärmung durch zu hohe Übergangswiderstände infolge der verringerten Kontaktftäche des Messers entsteht und da ferner der Materialaufwand ein sehr großer ist.to a disproportionately large one. There are z. B. Knife guides where the Switch blade has a guide slot either in the middle or on the lower edge. This type of construction is particularly useful for switches with higher currents impractical, as there is a risk of heating up due to excessively high contact resistance the reduced contact area of the knife arises and there is also the cost of materials is a very big one.

Vorliegende Erfindung will diese Nachteile vermeiden und eine einfache und sichere Führung der Schaltmesser ermöglichen.The present invention aims to avoid these disadvantages and to provide a simple and safe guide enable the switch knife.

Die Art der Ausführung dieser dem Erfindungsgedanken zugrunde liegenden Messerführung ist aus der Zeichnung ersichtlich. Das Messer α wird in länglichen-Schlitzen der zwei seitlichen Lappen c des Bügels b geführt. In dem Mittelstück des Bügels b ist ein Bolzen d angebracht, der in einem Loch der 3" Kontaktfeder e drehbar gelagert ist. Da die Lagerung des Bolzens d nur in dem einen Schenkel der Kontaktfeder e angeordnet ist, kann sich das Messer ohne weiteres zwischen den Klemmflächen der Kontaktfedern hin und her bewegen. Abb. ι zeigt die Gesamtanordnung der Erfindung. Abb. 2 zeigt einen senkrechten Schnitt des Führungsbügels mit dem Bolzen und seiner drehbaren Lagerung. Abb. 3 gibt einen waagerechten Schnitt der Bügelanordnung mit der Bolzenlagerung.The type of execution of this knife guide on which the concept of the invention is based can be seen from the drawing. The knife α is guided in elongated slots of the two side tabs c of the bracket b. In the center piece of the bracket b a bolt d is attached, which is rotatably mounted in a hole of the 3 "contact spring e . Since the mounting of the bolt d is only arranged in one leg of the contact spring e , the knife can easily move between the Move the clamping surfaces of the contact springs back and forth. Fig. 1 shows the overall arrangement of the invention. Fig. 2 shows a vertical section of the guide bracket with the bolt and its rotatable mounting. Fig. 3 shows a horizontal section of the bracket assembly with the bolt mounting.
