Description

Schmelzleiter für Sicherungspatronen Zusatz zum Patent 723 352 Die Erfindung betrifft Sicherungspatronen für höhere Nennstromstärken, die nach Patent 723 352 mit Schmelzleitern, die seileckaftig von der Innenwandung der Patronenhülse abgehalten sind, um diese von den Einwirkungen des Unterbrecherlichtbogens fernzuhalten, ausgestattet sind.Fusible link for fuse cartridges Addition to patent 723 352 Die Invention relates to fuse cartridges for higher rated currents, according to patent 723 352 with fusible conductors that form a rope corner from the inner wall of the cartridge case are held in order to keep them away from the effects of the interrupter arc, are equipped.

Die vorliegende Erfindung bietet nun gegenüber den im Hauptpatent beschziebenen Schmelzleiterabstützungen eine wesentliche Vereinfachung der Abstützung dadurch, daß sich; die durchgehenden, an den Stützstellen entsprechend eingeknickten - Schmelzleiter unmittelbar selbst gegen die Patronenwandung abstützen. Im besonderen erhalten dabei die durchgehenden Schmel'zleiterstreifen auf der Spannstrecke von einem Ende der Patrone bis zum anderen zwei V-förmige Einknickungen, so daß die Spitzen dieser V-Formen auf der Patroneninnenwandung stehen und die zwischen deinEinknickungenliegende Schmelzl.eiterstrecke einen gleichmäßigen Abstand von der Wandung einhält.The present invention now offers over those in the main patent Described fusible conductor supports a significant simplification of the support by the fact that; the continuous ones, kinked accordingly at the support points - Support the fuse element directly against the cartridge wall. In particular receive the continuous melting conductor strips on the span from one end of the cartridge to the other two V-shaped indentations so that the The tips of these V-shapes stand on the inside wall of the cartridge and the one between your bends The fusible link line maintains an even distance from the wall.

In der Zeichnung ist der Gegenstand der Erfindung in einer beispielsweisen Ausführung des näheren veranschaulicht. Abb. i stellt die Sicherungspatrone im Längsschnitt und Abb. 2 den Schmelzleiter in der Schrägansicht dar.In the drawing, the subject matter of the invention is in an exemplary manner Execution of the more detailed illustrates. Fig. I shows the fuse cartridge in longitudinal section and Fig. 2 shows the fusible conductor in an oblique view.

Darnach besteht der- Schmefz1eiter aus durchgehenden Metallstreifen, dessen abgebogene Enden a über den Rand der Patronenhälse gebogen und durch die Kontaktkappen b gehalten sind. Erfindungsgemäß hat der Schmelzleiter eine, zwei, wie dargestellt, oder mehrere V-förmige Einknicku.ngen c derart, daß die Spitzen dieser Einknickungen sich beim Einspannen der Leiterstreifen in die Patronenhülsed gegen die Innenwandung anstellen und den Leiter damit abstützen. Auf diese einfache Weise sind die Leiter, insbesondere die zwischen den beiden dargestellten Einknickungen liegende Strecke, von; der Innenwandung abgehalten und es ist zugleich der Abstand untereinander gesichert.According to this, the melting point consists of continuous metal strips, whose bent ends a bent over the edge of the cartridge necks and through the Contact caps b are held. According to the invention, the fusible link has one, two, as shown, or several V-shaped Einknicku.ngen c such that the tips these kinks occur when the conductor strips are clamped into the cartridge case Place against the inner wall and use it to support the ladder. On this simple one Wise are the conductors, especially the kinks shown between the two lying distance, from; the inner wall held and it is at the same time the distance secured among each other.
