Description

Schmelzleiter für elektrische Sicherungen Zusatz zum Patent 668 923 Der dem Patent 668 923 zugrunde liegende Erfindungsgedanke besteht darin, unter Verwendung von Kapillarkräften eine Unterbrechungsstelle im Schmelzleiter einer elektrischen Sicherung in dem Augenblick sicher zu erzeugen, in dem die Schmelztemperatur des niedrig schmelzenden Metalls erreicht ist. Zur Lösung dieser Aufgabe wird vorgeschlagen, an der vorbestimmten Trennstelle des Schmelzleiters Rillen, Bohrungen oder andere zusätzlich angebrachte Einrichtungen vorzusehen, die Kapillarkräfte erzeugen.Fusible conductor for electrical fuses Addendum to patent 668 923 The idea of the invention on which patent 668 923 is based is to use capillary forces to safely create an interruption point in the fusible conductor of an electrical fuse at the moment when the melting temperature of the low-melting metal is reached. To solve this problem, it is proposed to provide grooves, bores or other additionally attached devices that generate capillary forces at the predetermined separation point of the fusible conductor.

Die Erfindung bezweckt eine weitere Ausbildung der besonderen Schmelzleiteranordnung des Hauptpatents 668 923. Es ist nämlich beobachtet worden, daß durch die gegebenenfalls sich auf der Oberfläche des niedrig schmelzenden Metalls bildende Oxydhaut eine Erschwerung im Fortfließen desselben eintritt, so daß die Kapillarkräfte mit. ur4er nicht ausreichen, die angestrebte Wirkung rechtzeitig herbeizuführen.The invention aims at a further development of the special fusible conductor arrangement of the main patent 668 923. It has been observed that by the possibly oxide skin forming on the surface of the low-melting metal Difficulty in the flow of the same occurs, so that the capillary forces with. ur4er are not sufficient to bring about the desired effect in time.

Dieser Mangel wird erfindungsgemäß- dadurch behoben, daß die als Kapillaren wirksamen Teile des Schmelzleiters mit einem überzug aus Weichlot versehen werden. Hierdurch ist die Oberfläche der Kapillaren gleichsam vorbenetzt, so daß ein Fließen des niedrig. schmelzenden Metalls wesentlich leichter und sicherer herbeigeführt .wird, ,ähnlich dem Vorgang, wie er eintritt, wenn. zwei auf ihrer Oberfläche verziunte Gegenstände zusammengelötet werden.According to the invention, this deficiency is remedied by the fact that the capillaries effective parts of the fusible conductor are provided with a coating of soft solder. As a result, the surface of the capillaries is prewetted, so to speak, so that flow des low. melting metal is brought about much more easily and safely .will,, similar to the process as it occurs when. two decorated on their surface Objects are soldered together.
