Description
Die vorliegende Erfindung betrifft ein Relais zum Schließen oder Unterbrechen des Stromkreises zwischen zwei Relaisanschlusskontakten, mit zwei Kontaktfedern, die jeweils mit ihren einander abgewandten Federenden an den Relaisanschlusskontakten elektrisch leitend befestigt und mit ihren anderen, auslenkbaren freien Federenden einander zugewandt sind, mit Kontakten, an denen die freien Federenden in der geschlossenen Relaisposition anliegen und von der die freien Federenden in der geöffneten Relaisposition abgehoben sind, und mit einem einzigen Magnetantrieb zum synchronen, gleichläufigen Auslenken der beiden Kontaktfedern in die geschlossene oder die geöffnete Relaisposition.The present invention relates to a relay for closing or interrupting the circuit between two relay connection contacts, with two contact springs, each electrically connected to their opposite ends of the relay terminal contacts electrically conductive and with their other, deflectable free spring ends face each other, with contacts where the free spring ends abut in the closed relay position and from which the free spring ends are lifted in the open relay position, and with a single magnetic drive for synchronous, synchronous deflection of the two contact springs in the closed or open relay position.

Bei DC-Anwendungen, insbesondere in Fahrzeugen mit 24VDC bzw. 48VDC, kommt es darauf an, den beim Auslenken der Kontaktfeder in die geschlossenen Relaisposition kurzzeitig auftretenden Lichtbogen zwischen dem Relaiskontakt und der sich nähernden Kontaktfeder sicher und schnell zu löschen.For DC applications, especially in vehicles with 24VDC or 48VDC, it is important to safely and quickly extinguish the arcing between the relay contact and the approaching contact spring when the contact spring is deflected into the closed relay position.
Es die Aufgabe der vorliegenden Erfindung, ein Relais mit Doppelunterbrechung anzugeben.It is the object of the present invention to provide a relay with double break.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Kontakte durch eine stationäre, elektrisch leitende Kontaktbrücke gebildet sind.This object is achieved in that the contacts are formed by a stationary, electrically conductive contact bridge.
Die erfindungsgemäße synchrone Doppelunterbrechung des Stromkreises mit zwei in Reihe geschalteten Kontaktfedern bewirkt eine Halbierung der jeweils auftretenden Lichtbogenenergie. Die Kontaktbrücke ist im Relaisgehäuse ortsfest gehalten und verbindet die beiden Kontaktfedern in der geschlossenen Relaisposition.The inventive synchronous double interruption of the circuit with two series-connected contact springs causes a halving of each occurring arc energy. The contact bridge is held stationary in the relay housing and connects the two contact springs in the closed relay position.
Bevorzugt ist der Magnetantrieb als Hubmagnet mit einem in einer Magnetspule linearbeweglich geführten Tauchkern ausgebildet, mit dem die freien Federenden bewegungsgekoppelt sind. Der Hubmagnet kann monostabil oder bistabil ausgeführt sein. Statt einem Hubmagnet kann auch ein anderer Magnetantrieb eingesetzt werden, dessen Stellelement mit den freien Federenden in deren Auslenkrichtung bewegungsgekoppelt ist. So kann beispielsweise auch ein Magnetantrieb mit Drehanker eingesetzt werden, dessen Drehbewegung über ein linear linearbeweglich geführtes Kopplungselement zu einer Auslenkung der freien Federenden führt.Preferably, the magnetic drive is designed as a solenoid with a linearly guided in a magnetic coil plunger, with which the free spring ends are coupled for movement. The solenoid can be made monostable or bistable. Instead of a solenoid and another magnetic drive can be used, the actuator coupled in motion with the free spring ends in the deflection is. Thus, for example, a magnetic drive with rotary armature can be used, the rotational movement of which leads via a linearly linearly movably guided coupling element to a deflection of the free spring ends.
Weitere Vorteile und vorteilhafte Ausgestaltungen des Gegenstands der Erfindung sind der Beschreibung, der Zeichnung und den Ansprüchen entnehmbar.
