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.
