Description
Das Hauptpatent betrifft einen für elektrische Anlagen auf Fahrzeugen bestimmten vereinigten elektromagnetischen Regler und Schalter mit einer gemeinsamen Stromspule und einer Bimetallkontaktfeder am Schalter, die bei etwaigem Kurzschluß das Öffnen und Schließen des Schalters unter dem Einfluß desUnterbrecherfeuers periodisch unterbricht. Hierbei muß die Bimetallfeder einerseits unter normalen Betriebsbedingungen bei geschlossenem Schalter einen bestimmten Kontaktdruck gewährleisten, damit sich der Schalter bei Erschütterungen im Fahrbetrieb nicht unzeitig öffnet und anderseits beim Erwärmen durch das Unterbrecherfeuer sich in der gewünschten Weise krümmen. Diese beiden Eigenschaften lassen sich bei einer einzigen Feder nicht immer leicht vereinigen.The main patent relates to a united one intended for electrical systems on vehicles electromagnetic regulator and switch with a common current coil and a Bimetal contact spring on the switch that opens and closes in the event of a short circuit periodically interrupts the switch under the influence of the interrupter fire. Here must the Bimetal spring on the one hand under normal operating conditions with the switch closed Ensure a certain contact pressure so that the switch is in the event of vibrations during driving does not open prematurely and on the other hand bend in the desired way when heated by the interrupter fire. These Both properties cannot always be easily combined with a single spring.
Diese Schwierigkeit wird gemäß der Erfindung dadurch behoben, daß die Schalterkontaktfeder in der Weise aus zwei getrennten einander verlängernden Teilen zusammengesetzt ist, daß das frei bewegliche Ende der Schalterkontaktfeder aus Bimetall gefertigt und an einem das andere Ende der Schalterkontaktfeder bildenden Fuß aus gewöhnlichem federndem Werkstoff befestigt wird. Dadurch wird der Vorteil erzielt, daß die gewöhnliche Feder entsprechend dem gewünschten Kontaktdruck und die Bimetallfeder entsprechend der gewünschten Wärmeempfindlichkeit gewählt werden kann.This problem is solved according to the invention in that the switch contact spring composed in the manner of two separate mutually extending parts is that the freely movable end of the switch contact spring made of bimetal and attached the other end of the switch contact spring forming a foot made of ordinary resilient Material is attached. This has the advantage that the ordinary spring according to the desired contact pressure and the bimetal spring according to the desired Heat sensitivity can be chosen.
Die Aufteilung der Schalterkontaktfeder ermöglicht, die Bimetallfeder nur in Nähe der von den Öffnungsfunken des Schalters gebildeten Wärmequelle anzuordnen, so daß eine gleichmäßigere Erwärmung der Bimetallfeder als bei einer vollständig aus Bimetall bestehenden Schalterkontaktfeder erzielt wird. Bei normaler Erwärmung im Betrieb verändert sich die Schalterkontaktfeder gemäß der Erfindung thermisch weniger als eine ganz aus Bimetall bestehende Feder bei gleichem Verhalten gegenüber dem Kurzschluß, und die Einstellwerte für normalen Betrieb sind im Vergleich zu einer kein Bimetall enthaltenden, gewöhnlichen Schalterkontaktfeder nur wenig verändert.The division of the switch contact spring allows the bimetal spring only in the vicinity of the to arrange the heat source formed by the opening sparks of the switch, so that a more uniform Heating of the bimetallic spring than is achieved with a switch contact spring made entirely of bimetal. With normal Heating during operation changes the switch contact spring according to the invention thermally less than a spring made entirely of bimetal with the same behavior the short circuit, and the setting values for normal operation are ordinary as compared with one containing no bimetal Switch contact spring changed only a little.
Bei einem bekannten vereinigten elektromagnetischen Reglerschalter besteht die Bimetallkontaktfeder aus zwei zusammengeschweißten Federn aus Stahl und Nickel, wobei die Stahlfeder an beiden Enden über die Nickelfeder hervorsteht. Hierbei wird jedoch die Bimetallfeder durch die allgemeine Wärme des Geräts beeinflußt. Ferner gibt es schon elektrische Wärmeschalter mit Bimetällfedern, an denen gewöhnliche Federn befestigt sind. Bei diesen Schaltern wird aber das Bimetall von dem hindurchfließenden Strom erwärmt.In a known unified electromagnetic regulator switch, there is a bimetallic contact spring made of two steel and nickel springs welded together, the steel spring at both ends over the nickel spring protrudes. Here, however, the bimetal spring is affected by the general warmth of the Device affected. There are also electrical heat switches with bimetallic springs to which ordinary springs are attached. In these switches, however, the bimetal is from heated by the current flowing through it.
