Patentiert im Deutschen Reiche vom 7.JuIi 1914 ab.Patented in the German Empire on July 7, 1914.

Die Erfindung erstreckt sich auf Schmelzpatronen, deren aufgeschraubte Endkappen und innere Klemmorgane ein Schmelzelement zwischen sich festklemmen. Die Erfindung besteht. im wesentlichen darin, daß der Abstand zwischen den Klemmorganen an der Austrittsstelle des Schmelzelements aus dem inneren Klemmorgan vergrößert ist.The invention extends to melt cartridges, their screwed-on end caps and inner clamping members clamp a fusible element between them. The invention consists. essentially that the distance between the clamping members on the The exit point of the fusible element from the inner clamping member is enlarged.

Die Zeichnung veranschaulicht mehrere Ausführungsformen der Erfindung.The drawing illustrates several embodiments of the invention.

Die inneren Klemmorgane 3 können die Form einer Scheibe (Fig. 1, 2, 6 und 7), eines einfachen vollen Stöpsels (Fig. 3 und 4) oder eines gegabelten Stöpsels (Fig. 5) haben. Wie in Fig. i, 3, 4 und 5 gezeigt, ist die Klemmfläche des inneren Klemmorgans 3 konkav oder schüsselartig ausgebildet, und zwar befindet sich die größte Vertiefung der Fläche in der Nähe der Durchtrittsstelle für das Schmelzelement 4. Die gegenüberliegende Klemmfläche der Kappe 1 ist gerade gemacht, so daß zwischen den beiden Klemmflächen anThe inner clamping members 3 can be in the form of a disc (Fig. 1, 2, 6 and 7), one simple full plug (Fig. 3 and 4) or a forked plug (Fig. 5). As shown in Fig. i, 3, 4 and 5, the clamping surface of the inner clamping member 3 is concave or formed like a bowl, namely the largest depression of the surface is in the vicinity of the passage point for the fusible element 4. The opposite The clamping surface of the cap 1 is made straight so that between the two clamping surfaces

■ der Durchtrittsstelle des Schmelzelements ein vergrößerter Abstand entsteht und so eine relative Bewegung der Endkappe und des inneren Klemmorgans zwecks Herstellung eines Kontaktes mit dem Schmelzelement den Querschnitt und die Form des Schmelzelements an seiner Austrittsstelle in keiner Weise ändern kann. Dieselbe Wirkung kann dadurch erzielt werden, daß man, wie Fig. 2 zeigt, die Klemmfläche der Endkappe 1 entsprechend vertieft oder schüsselartig gestaltet. Auch kann man, wie in Fig. 6 und 7 gezeigt, das Klemmorgan 3 mit radialen Eindrückungen■ the passage point of the fusible element creates an enlarged distance and thus a relative Movement of the end cap and inner clamping member to make contact with the fusible element do not in any way change the cross section and the shape of the fusible element at its exit point can. The same effect can be obtained by, as shown in FIG. 2, the The clamping surface of the end cap 1 is correspondingly recessed or designed like a bowl. Even you can, as shown in Fig. 6 and 7, the clamping member 3 with radial indentations

Claims

Patent Claims:

provided, in which the end of the fusible element 4 is inserted, then the depth of the Indentations are such that screwing on the end cap cuts off the fusible element prevented at its exit point from the clamping member.

In the embodiment according to FIGS. 8 to 10, the inner clamping member is flexible or resilient, namely here either according to FIG. 8, a special spring 5 between inner Organ 3 and housing 2 switched on, or the spring 5 itself is, as in FIGS. 9 and 10 show, provided with the bowl-like surface and thus serves directly as a clamping member. These designs are preferable in cases where there is no sudden pressure to be exercised on the fusible element, such as when using a not resilient organ occurs.

The exerted on the end of the fusible element 4 when the cap 1 is screwed on Effect is illustrated in Fig. 11, from which it can be seen that the end of the Fusible element is pressed flat, however, even if the cap is up to the touch is screwed with the clamping member, a cutting of the fusible element can not occur, since its end in the Depression lies and does not extend to the edge of the clamping surfaces.

i. Melt cartridge, their screwed-on end caps and inner clamping elements

Clamp the fusible element between them, characterized in that the distance enlarged between the clamping members at the point of passage of the melting element is.

2. 'melt cartridge according to claim i, characterized in that the clamp surface of either the outer (i) or the inner clamping member (3) recessed like a bowl is.

3. melt cartridge according to claim 1 or 2, characterized in that one of the puts both clamping members resiliently against the melting element.
