Description

(N 23072(N 23072

Bekannt sind elektrische Wärmeausschalter, bei denen zwei Metalle durch ein Lot verbunden sind, von denen das eine, unter Federspannung stehend, beim Schmelzen des Lotes einen elektrischen Ausschalter betätigt. Auch sind solche Wärmeausschalter bekannt, bei denen die durch Lot verbundenen Metallkörper sofort nach Betätigung des elektrischen Schalters wieder in ihre ursprüngliche Lage ίο zurückkehren. Die letzteren brauchen indessen viel Platz, der in vielen Fällen nicht zur Verfugung steht. Dieser Übelstand wird durch Anordnung gemäß der Erfindung vermieden, bei der die zum Ein- und Ausschalten dienenden Kontaktkörper konzentrisch oder symmetrisch zu den durch ein Lot verbundenen Metallkörpern angeordnet sind, indem hierbei die Raumbeanspruchung auf ein Mindestmaß beschränkt wird.Electrical thermal switches are known in which two metals are connected by a solder are, one of which, under spring tension, actuates an electric switch when the solder melts. Even such thermal switches are known in which the metal body connected by solder back to their original position immediately after actuating the electrical switch ίο return. The latter, however, need a lot of space, which in many cases does not have to Available. This disadvantage is avoided by an arrangement according to the invention, in which the contact bodies used for switching on and off are concentric or symmetrical to those connected by a solder Metal bodies are arranged by keeping the space occupancy to a minimum is restricted.

Abb. ι zeigt den Ausschalter in der Ansicht, Abb. 2 denselben im Schnitt, vergrößert gezeichnet. Fig. Ι shows the circuit breaker in the view, Fig. 2 the same in section, drawn enlarged.

In einem Gehäuse α befindet sich die durch Lösen der Schraubkappe b herausnehmbare Schmelzpatrone. Diese besteht aus dem BoI-zen c, der durch ein leicht schmelzbares Lot d The melt cartridge, which can be removed by loosening the screw cap b, is located in a housing α. This consists of the bolt c, which is replaced by an easily meltable solder d

mit der Hülse e verbunden ist, der Feder / und dem Knopf g aus Isolierstoff. In dem Gehäuse α sind die beiden Anschlußschrauben A1 und Ä2 isoliert eingeschraubt, an welchem S zwei Federn i1 und i2 befestigt sind. Eine starke Spiralfeder k, in dem Gehäuse isoliert gelagert, drückt gegen die Schmelzpatrone. Sobald das Lot d schmutzt, verschieben sich auf dem Bolzen c durch den Druck deris connected to the sleeve e , the spring / and the button g made of insulating material. In the housing α , the two connection screws A 1 and Ä 2 are screwed insulated, to which S two springs i 1 and i 2 are attached. A strong spiral spring k, mounted in an insulated manner in the housing, presses against the melting cartridge. As soon as the solder d gets dirty, the pressure of the shift on the bolt c

ίο 'Feder k die Hülse e und damit auch die Haltefedern I1 und 1?. Die frei gewordenen Federn/ können jetzt den Bolzen nicht mehr halten, und dieser entgleitet zusammen mit der Hülse e, die von den Anschlägen tn1 und m2 aufgehalten wird, dem Bereich der Kontaktfedern i1 und /2, wodurch der Stromkreis unterbrochen wird. Die Feder / führt die Hülse e und den Bolzen c nach erfolgter Stromunterbrechung in ihre .ursprünglicheίο 'spring k the sleeve e and thus also the retaining springs I 1 and 1 ?. The vacated springs / can now bolt no longer keep up, and this slipping is stopped together with the sleeve e, the tn of the stoppers 1 and m 2, the area of the contact springs i 1 and / 2, is interrupted causing the circuit. The spring / leads the sleeve e and the bolt c to their .original one after the current interruption
