Description

Bei einer Ausführungsform des Gegenstandes des Hauptpatentes ist durch Schmelzlot eine am Ende 'eines Drahtes angebrachte Öse an dem Metallstück angelötet, in der eine gespannte Feder hängt. Die feinen Drähte dieser Öse werden am leichtesten in unmittelbarer Nähe ihres Austrittes aus der Lötstelle schadhaft, weil sie beim Fabrikationsprozeß hier die höchste Erwärmung erhalten, haben und hier das größte Biegemoment eintritt. Reißt num ein solcher feiner Draht, so kann es vorkommen, daß sich die Feder entspannt, ohne daß das Schmelzlot schmilzt und ohne daß der Strom unterbrochen wird. Die Schmelzsicherung wird dann beim Warmwerden picht mehr ordnungsgemäß unterbrochen. Das Wesen der Erfindung besteht darin, daß das Zugorgan in eine aus Draht gebogene Öse eingreift, vom dem. nur das eine Ende durch Schmelzlot an das Metallstück angelötet ist.In one embodiment of the subject of the main patent a mounted at the end 'of a wire loop is soldered to the metal piece by fusible link in which a tensioned spring depends. The fine wires of this eyelet are most easily damaged in the immediate vicinity of their exit from the soldering point, because this is where they have received the greatest warming during the manufacturing process and the greatest bending moment occurs here. If such a fine wire breaks, it can happen that the spring relaxes without the fusible link melting and without the current being interrupted. The fuse is then properly interrupted when it warms up. The essence of the invention is that the pulling element engages in an eyelet bent from wire, from the. only one end is soldered to the metal piece with a fusible link.

In der Abbildung ist der Gegenstand der Erfindung ,dargestellt. An Stelle der eingelöteten Öse wird der Draht 1 mit seinem Ende 2 durch das Lötmetall 3 nur mit einem Ende an das Metallstück 4 angelötet. Unmittelbar hinter der Lötstelle wird eine Öse 5 angebogen. Reißt nun der Draht an der Stelle 6, so ist die Schmelzsicherung schadhaft, zeigt aber dadurch auch an, daß sie nicht mehr in Ordnung ist. Es wind aber vermieden, daß leine schadhafte Schmelzsicherung unbeachtet als Sicherheitsorgan weiter Verwendung findet.In the figure, the object of the invention is shown. Instead of the soldered The wire 1 with its end 2 through the solder 3 with only one eyelet The end is soldered to the metal piece 4. Immediately behind the soldering point there is an eyelet 5 angled. If the wire breaks at point 6, the fuse is defective, but also indicates that it is no longer in order. But it is wind Avoided leash defective fuse going unnoticed as a safety organ Is used.
