Description

  

  Kondensator mit     Abreisssicherung       Die Neuerung bezieht sich auf einen explosions  geschützten Kondensator mit einem durch     Dehnungs-          sicken    verformten Metallgehäuse und einem axial durch  den Wickel hindurchgeführten, mit einer Sollbruchstelle  versehenen     Anschlussdraht.     



  Gemäss der Neuerung ist der     Abreissdraht    an seinem  aus dem Deckel herausragenden Ende derartig ver  formt, dass das herausragende Drahtende bei einer  Streckung des Gehäuses vom Deckel mitgenommen  wird.  



  Bei bekannten explosionssicheren Kondensatoren  mit     Abreisssicherung    ist der herausgeführte     Abre.issdraht     an einer     Anschluss'fahne    festgelötet. Dabei hat sich  gezeigt, dass die der Drucksteigerung vorausgehende  starke Erwärmung oft ausreicht, um diese     Lötverbin-          dung    zu lösen. Dadurch wird der     Abreissdraht    beim  Wegdrücken des Deckels nicht mitgenommen, so dass  kein Abreissen des Drahtes erfolgt. Ein     Explosions-          bzw.    Brandschutz ist in diesem Fall nicht Geboten.  



  Durch die neuerungsgemässe Ausbildung des Ab  reissdrahtes ist dieser Nachteil vermieden.  



  In der     Zeichnung    sind zwei Ausführungsbeispiele  des Neuerungsgegenstandes dargestellt. Es zeigt:       Fig.    l einen Längsschnitt durch einen Kondensator  mit     Abreissdraht,    dessen herausragendes Ende abge  bogen ist,       Fig.    2 einen Deckel eines Kondensators mit einem       Abreissdraht,    dessen herausragendes Ende breitge  quetscht ist.  



  Ein mit     Dehnungssicken    10 versehenes Metallge  häuse 11 ist mit einem Wickel 12 bestückt und mit    einem Deckel 13 aus Isolierstoff abgeschlossen. Die       Anschlussfahnen    sind durch einen Hohlniet am Deckel  befestigt. Durch den Hohlniet 14 der     Anschlussfahne     15 ist ein Ende 17 des     Abreissdrahtes    16 hindurchge  zogen und abgebogen. Im Inneren ist er axial durch  den Wickel hindurch zu einer Kontaktfläche 18 des  Wickels geführt. In der     :Mitte    hat der     Abreissdraht    eine  Sollbruchstelle 19.  



  Gemäss     Fig.    2 ist der     Abreissdraht    an seinem aus  dem Deckel herausragenden Ende 20 breitgequetscht.



  Capacitor with tear-off protection The innovation relates to an explosion-proof capacitor with a metal housing deformed by expansion beads and a connecting wire with a predetermined breaking point that is passed axially through the coil.



  According to the innovation, the tear-off wire is deformed at its end protruding from the cover in such a way that the protruding wire end is carried along by the cover when the housing is stretched.



  In known explosion-proof capacitors with tear-off protection, the tear-off wire that is led out is soldered to a terminal lug. It has been shown that the strong heating preceding the pressure increase is often sufficient to loosen this soldered connection. As a result, the tear-off wire is not taken along when the cover is pushed away, so that the wire does not tear. In this case, explosion or fire protection is not required.



  Due to the innovation according to the training of the tear wire from this disadvantage is avoided.



  Two exemplary embodiments of the subject of the innovation are shown in the drawing. It shows: Fig. 1 a longitudinal section through a capacitor with tear-off wire, the protruding end of which is bent abge, Fig. 2 a cover of a capacitor with a tear-off wire, the protruding end of which is broadly squeezed.



  A housing 11 provided with expansion beads 10 Metallge is equipped with a winding 12 and completed with a cover 13 made of insulating material. The connection lugs are attached to the cover with a hollow rivet. One end 17 of the tear-off wire 16 is pulled through the hollow rivet 14 of the connecting lug 15 and bent. Inside, it is guided axially through the roll to a contact surface 18 of the roll. In the middle, the tear-off wire has a predetermined breaking point 19.



  According to FIG. 2, the tear-off wire is squeezed wide at its end 20 protruding from the cover.
