Description
Schmelzsicherung, deren Schmelzmasse durch das Arbeitsglied verdrängt wird Es ist bekannt, die Schmelzmasse von Schmelzsicherungen durch das Arbeitsglied verdrängen zu lassen.Fuse, the melting mass of which is displaced by the working element It is known that the melting mass of fuses through the working link to be displaced.
Die Erfindung ermöglicht, Sicherungen dieser Art in jede Stellung zu bringen und die verdrängte Schmelzmasse unvermindert für ein Zurücklöten oder Sicherung verfügbar zu halten.The invention enables fuses of this type to be in any position to bring and the displaced melt mass undiminished for a back soldering or Keep backup available.
Die verdrängte Schmelzmasse wird hierzu von einer Kammer aufgenommen, welche durch das Arbeitsglied abgeschlossen ist.For this purpose, the displaced enamel mass is absorbed by a chamber, which is completed by the working link.
Die Zeichnung stellt ein Beispiel der neuen Vorrichtung ,dar. Abb. i ist eine Schnittansicht. Abb. 2 zeigt einen Schnitt durch die Vorrichtung .nach der Linie A-B oder Abb. i. Abb. 3 ist eine Unteransicht.The drawing shows an example of the new device. Fig. i is a sectional view. Fig. 2 shows a section through the device .nach the line A-B or Fig. i. Fig. 3 is a bottom view.
Als Arbeitsglied ist ein Stift i vorhanden, welcher durch eine Feder 2 gegen den Schmelzkörper 3 gedrückt wird. Der Stift hat hierzu einen Bund 4, mit dem er an dem Körper 3 liegt, und einen kolbenförmigen Teil 5 für den Angriff der Feder 2, die sich mit ihrem anderen Ende gegen das Gehäuse 6 stützt. Der Bund 4 ist .eine Verjüngung des Teiles 5. Der Körper 3 ist ein Ring, welcher in .dem hohlen Kern 7 der Heizspule.8 sitzt und z. B. aus Woodmetall besteht. Der Spulenkern 7, in welchem sich ,der Stift i mittels des Teiles 5 führt, ruht mit dem Isolierflansch 9 an einer Schulter io des Gehäuses 6. Vor dem anderen Isolierflansch i i des Spulenkernes. 7 ist ein Sprengring i2 in das Gehäuse 6 eingesetzt, der durch einen Schlitz 13 des Gehäuses zugänglich und so von seinem Sitz entfernbar ist. Nach Entfernen des Ringes 12 kann (der beschriebene Einbau aus dem Gehäuse herausgenommen und zerlegt werden. Der den Bund 4 umgebende Ringraum 14, welcher nach dem Innern des Gehäuses 6 hin durch den Teil 5 begrenzt ist, nimmt den beim Vorschub des Stiftes i verdrängten Teil der Schmelzmasse auf, so daß keine Schmelzmasse aus der Sicherung austreten kann. Das Eintreten der Schmelzmasse in,die Kammer 14 wird @dadurch gefördert, daß diese geheizt ist.A pin i is provided as the working element, which is pressed against the fusible body 3 by a spring 2. For this purpose, the pin has a collar 4 with which it lies on the body 3, and a piston-shaped part 5 for the engagement of the spring 2, which is supported with its other end against the housing 6. The collar 4 is .eine taper of part 5. The body 3 is a ring which sits in .dem hollow core 7 of the heating coil.8 and z. B. consists of Woodmetall. The coil core 7, in which the pin i is guided by means of the part 5, rests with the insulating flange 9 on a shoulder io of the housing 6. In front of the other insulating flange ii of the coil core. 7, a snap ring 12 is inserted into the housing 6, which snap ring is accessible through a slot 13 in the housing and can thus be removed from its seat. After removing the ring 12, the installation described can be removed from the housing and dismantled. The annular space 14 surrounding the collar 4, which is delimited towards the interior of the housing 6 by the part 5, takes the part displaced when the pin i is advanced The entry of the molten mass into the chamber 14 is promoted by the fact that it is heated.
Um die Vorrichtung zurückzulöten, erwärmt man sie z. B. durch einen die Spule 8 durchfließenden Strom. Die Vorrichtung wird dabei in der durch Abb: i veranschaulichten Lage gehalten, so @daß ,die durch das Erwärmen wieder geschmolzene Masse sich unter der Kammer 14 sammelt, um nach dem Erstarren wieder den gezeichneten Schmelzkörper 3 zu bilden.To solder back the device, it is heated e.g. B. by a the coil 8 current flowing through it. The device is shown in Fig: i held the illustrated position so @ that, the melted again by the heating Mass collects under the chamber 14 to return to that shown after solidification To form melt body 3.
