Description

Gegenstand des Patents 588 366 ist ein klotzförmiger Kontaktfinger, insbesondere von geschwungener Form, der aus mehreren durch Nieten, Schrauben, Schweißen o. dgl. zu einem massiven Kontaktklotz starr verbundenen Teilen besteht und bei dem die beim Stanzen sich ergebenden Schnittflächen unmittelbar ■ mit dem Gegenkontakt bzw. mit dem feststehenden Kontaktsockel Berührung haben.The subject of patent 588 366 is a block-shaped contact finger, in particular from curved shape, which is made up of several by riveting, screwing, welding or the like massive contact block rigidly connected parts and in which the punching resulting cut surfaces directly ■ with the mating contact or with the stationary Contact base.

Die vorliegende Erfindung sieht eine Weiterbildung derartiger Kontaktfinger vor, welche darin besteht, daß einzelne der parallel zur Ebene ihrer Bewegung aufeinandergeschichteten Platten- eines Kontaktfingers für die ganze Kontaktlänge bemessen und an der Eingriffstelle des Gegenkontaktes kürzere Platten seitlich von den längeren derart angeordnet sind, daß der Raum zwischen den langen Teilen zum Einbau anderer Konstruktionsteile, insbesondere von Schaltfedern, frei bleibt. Eine erfindungsgemäße Ausführungsform mit Zugfedern zwischen den Kontaktfingern ist besonders für solche Anordnungen geeignet, bei welchen sich die Finger an zwei Auflagestellen abstützen, die beispielsweise für die Ausschaltstellung beide auf dem Kontaktträger selbst liegen können. Die Lichtbogenfestigkeit der Anordnung kann im übrigen dadurch weiter verbessert werden, daß die kurzen, an der Schaltstelle befindlichen Teile aus einem gegen die Einwirkung des elektrischen Lichtbogens widerstandsfähigerem Material als die übrigen Teilstücke, z. B. aus Wolfram, hergestellt werden.The present invention provides a further development of such contact fingers, which consists in the fact that some of the layers are stacked parallel to the plane of their movement Plate-sized a contact finger for the entire contact length and attached to the Point of engagement of the mating contact shorter plates arranged laterally from the longer ones are that the space between the long parts for the installation of other structural parts, especially of switching springs, remains free. An embodiment according to the invention with tension springs between the contact fingers is particularly suitable for such arrangements in which the fingers are supported on two support points, for example for the switch-off position both can lie on the contact carrier itself. The arc resistance of the arrangement can be further improved by the fact that the short, at the switching point located parts made of a more resistant to the effects of the electric arc Material than the remaining sections, e.g. B. made of tungsten.

In der Abbildung ist ein Ausführungsbeispiel der Erfindung wiedergegeben. Das Kontaktfingerpaar besteht aus den langen Teilen α und den kurzen, an der Schaltstelle befindlichen Teilen b. Die langen Teile befinden sichan den Außenseiten und lassenzwischen sichRaum für die Kontaktfedern c. Die Kontaktfinger sind mit dem einen Stützpunkt am Kontaktträger d drehbar gelagert und mit Spiel auf die am Kontaktträger befestigten Bolzene aufgereiht. Die andere Abstützung erfolgt in der Einschaltstellung am beweglichen Kontakt (gestrichelt gezeichnet) oder in der Ausschaltstellung gegen das am Kontaktträger befestigte U-förmige Stück/. Die Teile α und b sind durch Nieten, Schweißen o. dgl. zu einem festen Stück miteinander verbunden. In the figure, an embodiment of the invention is shown. The pair of contact fingers consists of the long parts α and the short parts b located at the switching point. The long parts are on the outside and leave space between them for the contact springs c. The contact fingers are mounted rotatable d with a base on the contact carrier and lined up with the game on the attached to the contact carrier Bolzene. The other support takes place in the switched-on position on the movable contact (shown in dashed lines) or in the switched-off position against the U-shaped piece / attached to the contact carrier. The parts α and b are connected to one another to form a solid piece by riveting, welding or the like.
