Das obenstehende technische Problem wird durch die Merkmale des Anspruchs 1 gelöst.The above technical problem is solved by the features of
Demgemäß wird ein elektromechanisches Relais zum Einstecken in eine Reihenklemme geschaffen. Das Relais weist ein Magnetsystem auf, welches eine eine Längsachse aufweisende Spule, einen Spulenkern und einen Anker aufweist. Das Relais ist in einer Steckrichtung, die senkrecht zur Längsachse der Spule verläuft, in eine Reihenklemme einsteckbar. Der Anker ist in eine erste und eine zweite Lage schwenkbar bezüglich einer Achse gelagert, die senkrecht zur Längsachse der Spule und senkrecht zur Steckrichtung verläuft. Das elektromechanische Relais weist ferner ein Gehäuse auf, das eine erste und zweite Seitenfläche aufweist, die sich gegenüberstehen, jeweils senkrecht zur Längsachse der Spule angeordnet sind und jeweils eine Längsachse aufweisen, die parallel zur Steckrichtung verlaufen. Weiterhin weist das elektromechanische Relais einen ersten Wechselschalter auf, der zwei Festkontakte und eine Kontaktfeder aufweist, wobei die Kontaktfeder ein feststehendes Ende und einen zwischen den beiden Festkontakten bewegbaren, ein Kontaktelement tragenden Abschnitt aufweist. Zudem ist ein zweiter Wechselschalter vorgesehen, der zwei Festkontakte und eine Kontaktfeder aufweist, wobei die Kontaktfeder ein feststehendes Ende und einen zwischen den beiden feststehenden Kontakten bewegbaren, einen Kontaktelement tragenden Abschnitt aufweist, wobei der erste Wechselschalter und der zweite Wechselschalter entlang der Längsachsen der ersten und zweiten Seitenfläche an unterschiedlichen Orten innerhalb des Gehäuses angeordnet sind. Weiterhin weist das elektromechanische Relais eine Betätigungseinrichtung auf, welche die bewegbaren Abschnitte der Kontaktfedern des ersten und zweiten Wechselschalters mit dem Anker koppeln und entlang der Längsachsen der Seitenflächen bewegbar sind. Der eine Festkontakt des ersten Wechselschalters ist mit einem ersten Anschlusselement und der andere Festkontakt des ersten Wechselschalters ist mit einem zweiten Anschlusselement verbunden. Der eine Festkontakt des zweiten Wechselschalters ist mit einem dritten Anschlusselement verbunden, während der andere Festkontakt des zweiten Wechselschalters mit einem vierten Anschlusselement verbunden ist. Das feststehende Ende der Kontaktfeder des zweiten Wechselschalters ist mit einem fünften Anschlusselement verbunden, während das feststehende Ende der Kontaktfeder des ersten Wechselschalters mit einem sechsten Anschlusselement verbunden ist. Die Spule ist mit einem siebten und achten Anschlusselement verbunden. Die Anschlusselemente weisen jeweils einen außerhalb des Gehäuses liegenden externen Abschnitt auf und können beispielsweise als Anschlussstifte ausgebildet sein. Wenigstens eines der Anschlusselemente ist aus der ersten Seitenfläche und wenigstens ein weiteres der Anschlusselemente ist aus der zweiten Seitenfläche herausgeführt. Alternativ kann wenigstens eines der Anschlusselemente aus einem der beiden Seitenflächen herausgeführt sein.Accordingly, an electromechanical relay for plugging into a terminal block is provided. The relay has a magnet system which has a coil having a longitudinal axis, a coil core and an armature. The relay can be plugged into a terminal block in a plug-in direction that is perpendicular to the longitudinal axis of the coil. The armature is pivotably mounted in a first and a second position with respect to an axis which runs perpendicular to the longitudinal axis of the coil and perpendicular to the insertion direction. The electromechanical relay furthermore has a housing which has a first and second side surface, which face one another, are each arranged perpendicular to the longitudinal axis of the coil and each have a longitudinal axis which run parallel to the plug-in direction. Furthermore, the Electromechanical relay has a first changeover switch which has two fixed contacts and a contact spring, the contact spring having a fixed end and a section which can be moved between the two fixed contacts and carries a contact element. In addition, a second changeover switch is provided, which has two fixed contacts and a contact spring, the contact spring having a fixed end and a section that supports a contact element and is movable between the two fixed contacts, the first changeover switch and the second changeover switch along the longitudinal axes of the first and the second changeover switch second side surface are arranged at different locations within the housing. Furthermore, the electromechanical relay has an actuating device which couple the movable sections of the contact springs of the first and second changeover switches to the armature and can be moved along the longitudinal axes of the side surfaces. One fixed contact of the first changeover switch is connected to a first connection element and the other fixed contact of the first changeover switch is connected to a second connection element. One fixed contact of the second changeover switch is connected to a third connection element, while the other fixed contact of the second changeover switch is connected to a fourth connection element. The fixed end of the contact spring of the second changeover switch is connected to a fifth connection element, while the fixed end of the contact spring of the first changeover switch is connected to a sixth connection element. The coil is connected to a seventh and eighth connection element. The connection elements each have an external one located outside the housing Section and can be designed, for example, as connecting pins. At least one of the connection elements is led out of the first side surface and at least another one of the connection elements is led out of the second side surface. Alternatively, at least one of the connection elements can be led out of one of the two side surfaces.
Gemäß einer vorteilhaften Weiterbildung weist das Gehäuse eine an die erste und zweite Seitenfläche angrenzende Grundfläche auf, die senkrecht zur Steckrichtung angeordnet ist. Wenigstens zwei der Anschlusselemente sind an separaten Austrittsstellen aus der ersten Seitenfläche und wenigstens zwei andere der Anschlusselemente an separaten Austrittstellen aus der zweiten Seitenfläche herausgeführt.According to an advantageous development, the housing has a base area adjoining the first and second side surfaces, which is arranged perpendicular to the plug-in direction. At least two of the connection elements are led out of the first side face at separate exit points and at least two others of the connection elements are led out of the second side face at separate exit points.
Die externen Abschnitte der an der ersten und zweiten Seitenfläche herausgeführten Anschlusselemente erstrecken sich jeweils wenigstens abschnittsweise entlang der Längsachse der Spule. Die separaten Austrittsstellen der ersten Seitenfläche weisen wie die separaten Austrittstellen der zweiten Seitenfläche unterschiedliche Abstände zur Grundfläche auf. Die externen Abschnitte der an der ersten Seitenfläche herausgeführten Anschlusselemente haben jeweils eine Erstreckung entlang der Längsachse der Spule, die mit dem Abstand der Austrittstellen der ersten Seitenfläche zur Grundfläche zunimmt. In ähnlicher Weise haben die externen Abschnitte der an der zweiten Seitenfläche herausgeführten Anschlusselemente jeweils eine Erstreckung entlang der Längsachse der Spule, die mit dem Abstand der Austrittstellen der zweiten Seitenfläche zur Grundfläche zunimmt.The external sections of the connection elements led out on the first and second side surfaces each extend at least in sections along the longitudinal axis of the coil. The separate exit points of the first side face, like the separate exit points of the second side face, have different distances from the base area. The external sections of the connection elements led out on the first side surface each have an extension along the longitudinal axis of the coil which increases with the distance between the exit points of the first side surface and the base surface. In a similar way, the external sections of the connection elements led out on the second side surface each have an extension along the longitudinal axis of the coil which increases with the distance between the exit points of the second side surface and the base surface.
Um die Abstände zwischen den Anschlusselementen vergrößern und die elektrische Isolation zwischen den Anschlusselementen erhöhen zu können, kann der Abstand von der Grundfläche zum ersten Wechselschalter kleiner sein als der Abstand von der Grundfläche zum zweiten Wechselschalter. In diesem Fall ist das fünfte Anschlusselement, welches mit dem feststehenden Ende der Kontaktfeder des zweiten Wechselschalters verbunden ist, aus der ersten Seitenfläche herausgeführt, das dritte Anschlusselement, welches mit einem der Festkontakte des zweiten Wechselschalters verbunden ist, aus der zweiten Seitenfläche herausgeführt, das vierte Anschlusselement, welches mit dem anderen Festkontakt des zweiten Wechselschalters verbunden ist, aus der zweiten Seitenfläche herausgeführt, das erste Anschlusselement, welches mit einem der Festkontakte des ersten Wechselschalters verbunden ist, aus der ersten Seitenfläche herausgeführt. Die externen Abschnitte des ersten und fünften Anschlusselements erstrecken sich jeweils entlang der Längsachse der Spule, wobei der externe Abschnitt des ersten Anschlusselements einen kleineren Abstand zur Grundfläche hat als der externe Abschnitt des fünften Anschlusselements, und wobei der externe Abschnitt des ersten Anschlusselements entlang der Längsachse der Spule kürzer ist als der externe Abschnitt des fünften Anschlusselements. In ähnlicher Weise können sich die externen Abschnitte des dritten und vierten Anschlusselements jeweils entlang der Längsachse der Spule erstrecken, wobei der externe Abschnitt des vierte Anschlusselements einen kleineren Abstand zur Grundfläche hat als der externe Abschnitt des dritten Anschlusselements, und wobei der externe Abschnitt des vierten Anschlusselements entlang der Längsachse der Spule kürzer ist als der externe Abschnitt des dritten Anschlusselements.In order to increase the distances between the connection elements and to be able to increase the electrical insulation between the connection elements, the distance from the base area to the first changeover switch can be smaller than the distance from the base area to the second changeover switch. In this case, the fifth connection element, which is connected to the fixed end of the contact spring of the second changeover switch, is led out of the first side surface, the third connection element, which is connected to one of the fixed contacts of the second changeover switch, is led out of the second side surface, and the fourth Connection element, which is connected to the other fixed contact of the second changeover switch, led out of the second side surface, the first connection element, which is connected to one of the fixed contacts of the first changeover switch, passed out of the first side surface. The external sections of the first and fifth connection element each extend along the longitudinal axis of the coil, the external section of the first connection element being at a smaller distance from the base area than the external section of the fifth connection element, and the external section of the first connection element along the longitudinal axis of the Coil is shorter than the external portion of the fifth connection element. In a similar manner, the external sections of the third and fourth connection element can each extend along the longitudinal axis of the coil, the external section of the fourth connection element being at a smaller distance from the base than the external section of the third connection element, and the external section of the fourth connection element along the longitudinal axis of the coil is shorter than the external portion of the third connection element.
Eine kompakte Bauweise kann erreicht werden, wenn das feststehende Ende der Kontaktfeder des ersten Wechselschalters in der Nähe der zweiten Seitenfläche und das Kontaktelement des bewegbaren Abschnitt der Kontaktfeder des ersten Wechselschalters sowie die Festkontakte des ersten Wechselschalters in der Nähe der ersten Seitenfläche angeordnet sind, während das feststehende Ende der Kontaktfeder des zweiten Wechselschalters in der Nähe der ersten Seitenfläche und das Kontaktelement des bewegbaren Abschnitts der Kontaktfeder des zweiten Wechselschalters sowie die Festkontakte des zweiten Wechselschalters in der Nähe der zweiten Seitenfläche angeordnet sind.A compact design can be achieved if the fixed end of the contact spring of the first changeover switch in the vicinity of the second side surface and the contact element of the movable section of the contact spring of the first changeover switch and the fixed contacts of the first changeover switch are arranged in the vicinity of the first side surface, while the fixed end of the contact spring of the second changeover switch in the vicinity of the first side surface and the contact element of the movable section of the contact spring of the second changeover switch and the fixed contacts of the second changeover switch are arranged in the vicinity of the second side surface.
Auf diese Weise können sich die beiden Kontaktfedern fast über die gesamte Länge des Relaisgehäuses zwischen den beiden Seitenflächen und im Wesentlichen parallel zueinander erstrecken.In this way, the two contact springs can extend over almost the entire length of the relay housing between the two side surfaces and essentially parallel to one another.
Eine symmetrische Anordnung der Anschlusselemente kann erreicht werden, wenn die externen Abschnitte des ersten und vierten Anschlusselements in einer ersten Ebene, die im Wesentlichen parallel zur Längsachse der Spule verläuft, liegen, während die externen Abschnitte des dritten und fünften Anschlusselements in einer zweiten Ebene, die im Wesentlichen parallel zur Längsachse der Spule verläuft, liegen. Die erste Ebene weist zur Grundfläche einen kleineren Abstand als die zweite Ebene auf.A symmetrical arrangement of the connection elements can be achieved if the external sections of the first and fourth connection elements lie in a first plane, which runs essentially parallel to the longitudinal axis of the coil, while the external sections of the third and fifth connection elements lie in a second plane, which runs essentially parallel to the longitudinal axis of the coil. The first level is at a smaller distance from the base area than the second level.
Um den Abstand und die elektrische Isolation zwischen den Anschlusselementen weiter verbessern zu können, kann der externe Abschnitt des zweiten Anschlusselements, welcher mit dem anderen Festkontakt des ersten Wechselschalters verbunden ist, an einer weiteren Austrittstelle aus der ersten Seitenfläche herausgeführt sein und sich in Steckrichtung erstrecken, während der externe Abschnitt des sechste Anschlusselements, welches mit dem feststehenden Ende der Kontaktfeder des ersten Wechselschalters verbunden ist, an einer weiteren Austrittstelle aus der zweiten Seitenfläche herausgeführt ist und sich in Steckrichtung erstreckt. Die weiteren Austrittstellen liegen in einer dritten Ebene, die im Wesentlichen parallel Grundfläche verläuft, wobei die dritte Ebene einen kleineren Abstand zur Grundfläche aufweist als die erste Ebene.In order to be able to further improve the distance and the electrical insulation between the connection elements, the external section of the second connection element, which is connected to the other fixed contact of the first changeover switch, can be led out of the first side surface at a further exit point and extend in the plugging direction, while the external section of the sixth connection element, which is connected to the fixed end of the contact spring of the first changeover switch, is led out of the second side surface at a further exit point and extends in the plug-in direction. The further exit points lie in a third plane which runs essentially parallel to the base area, the third plane being at a smaller distance from the base area than the first plane.
Eine kompakte Bauweise kann sich vorzugsweise dadurch ergeben, dass die Betätigungseinrichtung einen ersten und einen zweiten Betätiger aufweist, wobei der erste Betätiger mit dem bewegbaren Abschnitt der Kontaktfeder des ersten Wechselschalters und der zweite Betätiger mit dem bewegbaren Abschnitt der Kontaktfeder des zweiten Wechselschalters verbunden ist, dass das Magnetsystem, z.B. die Spule oder der Spulenkern, eine der ersten Seitenfläche zugewandte erste Stirnseite und eine der zweiten Seitenfläche zugewandte zweite Stirnseite aufweist, dass der erste Betätiger zwischen der ersten Seitenfläche und der ersten Stirnseite und der zweite Betätiger zwischen der zweiten Stirnseite des Magnetsystems und der zweiten Seitenfläche angeordnet ist, und dass der Anker zwischen dem ersten und zweiten Betätiger angeordnet ist und eine Überhubfeder trägt, deren eine Ende mit dem ersten Betätiger und deren andere Ende mit dem zweiten Betätiger in Eingriff steht. Der erste und zweite Betätiger können jeweils stangen- oder stabförmig ausgebildet sein.A compact design can preferably result from the fact that the actuating device has a first and a second actuator, the first actuator being connected to the movable section of the contact spring of the first changeover switch and the second actuator being connected to the movable section of the contact spring of the second changeover switch, that the magnet system, for example the coil or the coil core, has a first end face facing the first side face and a second face face facing the second side face, the first actuator between the first side face and the first end face and the second actuator between the second face face of the magnet system and the second side surface is arranged, and that the armature is arranged between the first and second actuator and carries an overtravel spring, one end of which with the first actuator and the other end with the second actuator is engaged. The first and second actuators can each be rod-shaped or rod-shaped.
Vorzugsweise sind die externen Abschnitte des siebten und achten Anschlusselements aus der Grundfläche herausgeführt und erstrecken sich in Steckrichtung.The external sections of the seventh and eighth connection elements are preferably led out of the base area and extend in the plugging direction.
Um eine kompakte Bauweise zu erhalten, können der Anker, die Spule und die Kontaktfedern in einer Sandwich-Struktur angeordnet sein und jeweils eine längliche Erstreckung entlang der Längsachse der Spule aufweisen.In order to obtain a compact design, the armature, the coil and the contact springs can be arranged in a sandwich structure and each have an elongated extension along the longitudinal axis of the coil.
Auf diese Weise können die Kontaktfedern länger als beim Stand der Technik ausgeführt und derart angeordnet sein, dass sich eine höhere elektrische Isolation zwischen den Kontaktfedern erreichen lässt als bei bekannten vergleichbaren Lösungen, die zum Beispiel aus der
