Description

  

      Vereinigter    elektromagnetischer Regler und Sehalter mit einer gemeinsamen Stromspule,  insbesondere für elektrische     Anlagen    auf Fahrzeugen.    Das Hauptpatent Nr. 137319 betrifft  einen vereinigten elektromagnetischen Regler  und Schalter mit einer     Bimetallkontaktfeder,     die zum Beispiel bei einem etwaigen Kurz  schluss den Schalter unter dem Einfluss des       Unterbrecherfeuers    öffnet oder schliesst.

   Hier  bei muss die     Bimetallfeder    einerseits unter  normalen     Betriebsbedingungen    bei geschlos  senem Schalter einen bestimmten Kontakt  druck gewährleisten, damit sich der Schalter  bei Erschütterungen im Fahrbetrieb nicht  unzeitig öffnet, und anderseits beim Er  wärmen durch das     Unterbrecherfeuer    sich in  der gewünschten     Weise    krümmen. Diese  beiden Eigenschaften lassen sich bei einer  einzigen Feder nicht immer leicht vereinigen.  



  Diese Schwierigkeit wird gemäss der Er  findung dadurch behoben, dass die Bimetall  feder an einer Stützfeder aus elektrisch  leitendem Werkstoff befestigt wird. Dadurch  wird der Vorteil erzielt, dass in bezug auf  Form und Dimension die     Stützfeder    ent-    sprechend dem gewünschten Kontaktdruck  und die     Bimetallfeder    entsprechend der ge  wünschten Wärmeempfindlichkeit gewählt  werden kann.  



  In der Zeichnung ist ein Ausführungs  beispiel des Erfindungsgegenstandes veran  schaulicht, und zwar zeigt       Fig.    1 den     Reglerschalter    im Schnitt, und       Fig.    2 die     Schalterkontaktfeder    in ver  grössertem Massstab.  



  Der     Reglerschalter    ist in der     Fig.    1 mit  geöffnetem Schalter dargestellt und hat ab  gesehen von der Ausführung der Schalter  kontaktfeder denselben Aufbau wie beim  Ausführungsbeispiel des Hauptpatentes. Die       Schalterkontaktfeder    besteht aus zwei Teilen,  nämlich einer Stützfeder a aus gewöhnlichem  Werkstoff, zum Beispiel     Tomback,    und einer  daran genieteten     Bimetallfeder    b, die den  Kontakt 9 des Schalters trägt. 12 ist der  feststehende Gegenkontakt des Schalters.

        Im Gegensatz zu dem gezeichneten Aus  führungsbeispiel des Hauptpatentes krümmt  sich die     Bimetallfeder    b unter dem     Einfluss     der     Unterbrecherfunken    beim Kurzschluss nach  dem festen     Oregenkontakt    12 hin, .so dass der  Schalter hierbei geschlossen wird. Beim Ab  kühlen krümmt sich die     Bimetallfeder    b  wieder in die gezeichnete Stellung zurück,  in der der Schalter geöffnet ist.  



  Bei dieser     Ausführungsform    kann der  Kontaktdruck am Schalter bei den in nor  malen Betrieb vorkommenden Temperaturen  unverändert bleiben. Ferner sind die beim       Kurzschluss    durch das Öffnen und Schliessen  des Schalters entstehenden Funken kleiner  als bei einer sich beim Erwärmen vom Gegen  kontakt abbiegenden     Bimetallfeder,    weil die  Kontaktfeder beim Erwärmen bestrebt ist,  den Schalter zu schliessen.  



  Die     Zusammensetzung    der     Schalterkon-          taktfeder    aus den beiden Teilen<I>a</I> und<I>b</I>  ermöglicht auf einfache Weise, die Feder-    kraft und die     Krümmung    beim Erwärmen in  der jeweils gewünschten Weise zu erzielen.  



  Anstatt, wie gezeichnet ist, die Bimetall  feder b an die Stützfeder a anzunieten,  können beide Federn zum Beispiel auch  durch Schweissen miteinander verbunden  werden.  



  Ferner kann beispielsweise die Feder a  anstatt am Magnetgestell auch am Anker  befestigt werden. In diesem Fall geht der  Strom von der Stromspule über das winkel  förmige     .Eisengestell,    die Aufhängefeder des  Ankers und den Anker zu der Stützfeder.



      Combined electromagnetic regulator and switch with a common current coil, in particular for electrical systems on vehicles. The main patent no. 137319 relates to a combined electromagnetic controller and switch with a bimetallic contact spring, which opens or closes the switch under the influence of the interrupter fire, for example in the event of a short circuit.

   Here at the bimetallic spring on the one hand must ensure a certain contact pressure under normal operating conditions when the switch is closed so that the switch does not open prematurely in the event of vibrations while driving, and on the other hand bend in the desired way when it is heated by the interrupter fire. These two properties cannot always be easily combined in a single spring.



  This difficulty is resolved according to the invention, that the bimetal spring is attached to a support spring made of electrically conductive material. This has the advantage that, with regard to shape and dimensions, the support spring can be selected according to the desired contact pressure and the bimetal spring can be selected according to the desired heat sensitivity.



  In the drawing, an embodiment example of the subject invention is illustrated, namely Fig. 1 shows the regulator switch in section, and Fig. 2 shows the switch contact spring on a larger scale ver.



  The regulator switch is shown in Fig. 1 with the switch open and has the same structure as in the embodiment of the main patent, seen from the execution of the switch contact spring. The switch contact spring consists of two parts, namely a support spring a made of ordinary material, for example Tomback, and a bimetal spring b riveted to it, which carries the contact 9 of the switch. 12 is the fixed mating contact of the switch.

        In contrast to the exemplary embodiment drawn from the main patent, the bimetallic spring b curves under the influence of the interrupter sparks in the event of a short circuit to the fixed ore contact 12, so that the switch is closed here. When cooling from the bimetallic spring b bends back into the position shown in which the switch is open.



  In this embodiment, the contact pressure on the switch can remain unchanged at the temperatures occurring in normal operation. Furthermore, the sparks generated during a short circuit by opening and closing the switch are smaller than with a bimetal spring that bends away from the counter-contact when heated, because the contact spring tries to close the switch when heated.



  The combination of the switch contact spring from the two parts <I> a </I> and <I> b </I> makes it possible in a simple manner to achieve the spring force and the curvature during heating in the respectively desired manner.



  Instead of riveting the bimetal spring b to the support spring a, as shown, the two springs can also be connected to one another by welding, for example.



  Furthermore, for example, the spring a can also be attached to the armature instead of the magnet frame. In this case the current goes from the current coil over the angled .Eisengestell, the suspension spring of the armature and the armature to the support spring.
