 EMI1.1 
 
 EMI1.2 
 einer V-förmigen Blattfeder, die mit ihren Schenkeln gegen die Wandung der Kontaktplattenbohrung drückt. Am unteren Ende der V-förmigen Feder ist der Kenndraht eingehängt. Beim   Durchschmelzen   des Sicherungsdrahtes springt die gespannte Blattfeder, die gleichzeitig Erkennungszeichen ist, aus der Bohrung der Patrone heraus. Der Vorteil dieser Blattfeder gegenüber den bekannten   Anzeigenvor-   richtungen (Springmelder mit Spiralfeder) ist neben der einfacheren Konstruktion eine wesentliche Vereinfachung in der Montage. 



   In der Zeichnung zeigt Fig. 1 den Querschnitt einer Sicherungspatrone 1 mit der Bohrung 5 und Nuten 6 für die eigentlichen   Sehmelzsilberdrähte   8. In der Mitte der Bohrung 5 ist die Kontaktplatte 2 eingesetzt, in deren Bohrung. 3 das Erkennungszeichen, das ist die Blattfeder 4, an der der Schmelzsilberdraht 8 a angelötet ist, sitzt. Bei Durchschmelzen des Silberdrahtes 8 a springt die Blattfeder 4 aus der Bohrung 3 der Kontaktplatte 2 heraus, wie dies in Fig. 2 angedeutet.

 EMI1.1
 
 EMI1.2
 a V-shaped leaf spring which presses with its legs against the wall of the contact plate bore. The identification wire is attached to the lower end of the V-shaped spring. When the fuse wire melts, the tensioned leaf spring, which is also the identification mark, jumps out of the bore of the cartridge. The advantage of this leaf spring compared to the known display devices (spring alarm with spiral spring) is, in addition to the simpler construction, a significant simplification in assembly.



   In the drawing, FIG. 1 shows the cross section of a fuse cartridge 1 with the bore 5 and grooves 6 for the actual silver silver wires 8. In the center of the bore 5, the contact plate 2 is inserted into its bore. 3 the identification symbol, that is the leaf spring 4, to which the fusible silver wire 8 a is soldered, sits. When the silver wire 8 a melts through, the leaf spring 4 jumps out of the bore 3 of the contact plate 2, as indicated in FIG.

PATENT-ANSPRUCH : Springmelder für Schmelzsicherungspatronen, dadurch gekennzeichnet, dass er aus einer zweischenkeligen V-förmig gebogenen Blattfeder besteht, deren Schenkeldruck derart gegen die Wandungen der Bohrung (3) gerichtet ist, dass die Blattfeder das Bestreben hat, aus der Bohrungsmündung herauszuspringen. EMI1.3 **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Spring alarm for fuse cartridges, characterized in that it consists of a two-legged V-shaped bent leaf spring, the leg pressure of which is directed against the walls of the bore (3) in such a way that the leaf spring tends to jump out of the bore mouth. EMI1.3 ** WARNING ** End of CLMS field may overlap beginning of DESC **.
