Abstract
Elektromagnetisches Stellglied (1), insbesondere Relais, mit einer Spule (5) und mindestens zwei in Reihen geschalteten Schaltern (10, 15) eines Laststromkreises (20), die durch die Spule (5) zum Öffnen und Schließen der Laststromkreises (20) synchron angesteuert werden, wobei Mittel (25,30) zur Bildung einer Rückstellkraftin voneinander unabhängige Komponenten auf die mindestens zwei Schalter (10,15) aufgeteilt sind, die einer durch ein Magnetfeld der Spule (5) gebildeten Anzugskraft entgegenwirken, dadurch gekennzeichnet, dass zwischen den mindestens zwei Schaltern (10,15) ein Diagnoseabgriff (35) angeordnet ist, wobei der Diagnosepfad zwischen dem Diagnoseabgriff (35) und einem Diagnoseanschluss (60) des elektromagnetischen Stellgliedslaushochohmigem Material gebildet ist.Electromagnetic actuator (1), in particular relay, with a coil (5) and at least two switches (10, 15) connected in series in a load circuit (20) which are synchronized by the coil (5) for opening and closing the load circuit (20) are controlled, whereby means (25, 30) for forming a restoring force are divided into independent components between the at least two switches (10, 15) which counteract a pulling force formed by a magnetic field of the coil (5), characterized in that between the A diagnostic tap (35) is arranged in at least two switches (10, 15), the diagnostic path being formed between the diagnostic tap (35) and a diagnostic connection (60) of the electromagnetic actuator high-resistance material.
Description
Stand der TechnikState of the art
Die Erfindung geht von einem elektromagnetischen Stellglied nach der Gattung des Hauptanspruchs aus.The invention is based on an electromagnetic Actuator from the genus of the main claim.
Es ist bereits das Mini-ISO-Relay
Aus der
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße elektromagnetische Stellglied mit den Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass die Mittel zur Bildung einer Rückstellkraft in voneinander unabhängige Komponenten auf die mindestens zwei Schalter aufgeteilt sind. Auf diese Weise lässt sich eine Sicherungsfunktion realisieren, bei der der Laststromkreis auch dann noch geschaltet werden kann, wenn einer der beiden Schalter in geschlossenem Zustand an seinem Schaltkontakt festschmilzt und nicht mehr geöffnet werden kann. Diese Sicherungsfunktion kann somit unter Verwendung nur eines einzigen, elektromagnetischen Stellgliedes realisiert werden und erfordert somit kein zusätzliches elektromagnetisches Stellglied. Somit werden Platz, Material und Kosten eingespart. Besonders vorteilhaft ist es, wenn zwischen den mindestens zwei Schaltern ein Diagnoseabgriff angeordnet ist, wobei der Diagnosepfad zwischen dem Diagnoseabgriff und einem Diagnoseanschluss aus hochohmigem Material gebildet ist. Auf diese Weise lässt sich ein defekter Schalter erkennen.The electromagnetic actuator according to the invention in contrast, with the features of the main claim Advantage that the means for forming a restoring force in each other independent Components on which at least two switches are divided. On leaves this way realize a safety function in which the load circuit also then can still be switched if one of the two switches in the closed state it melts on its switching contact and no longer open can be. This backup function can thus be used realized only a single, electromagnetic actuator and therefore does not require an additional electromagnetic actuator. This saves space, material and costs. Particularly advantageous it is when there is a diagnostic tap between the at least two switches is arranged, the diagnostic path between the diagnostic tap and a diagnostic connection is formed from high-resistance material. That way identify a defective switch.
Durch die im Unteranspruch aufgeführte Maßnahme ist eine vorteilhafte Weiterbildung und Verbesserung des im Hauptanspruch angegebenen elektromagnetischen Stellgliedes möglich.By the measure listed in the subclaim an advantageous further education and improvement of the main claim specified electromagnetic actuator possible.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigt die einzige Figur ein Ausführungsbeispiel eines erfindungsgemäßen elektromagnetischen Stellgliedes.An embodiment of the invention is shown in the drawing and in the description below explained in more detail. It the only figure shows an embodiment an electromagnetic according to the invention Actuator.
