Abstract

The system has at least two closure elements, further contact and actuator arrangement. Each closure element has its own actuator driven by a relay armature, the movable part of each closure element is positively coupled to the associated actuator in the contact opening direction and both actuators are positively coupled to the movable part of the further contact only in the direction towards the operating position. The system has at least two closure elements (10,20), a further contact (30) and an actuator arrangement with at least two parallel movable components that closes both closure elements and the further contact by moving a relay armature into its operating position and opens both closure elements by returning the armature to its rest position, but prevents restoration of the further contact if one closure element does not open. Each closure element has its own actuator (40,50) driven by the relay armature, the movable part of each closure element is positively coupled to the associated actuator in the contact opening direction and both actuators are positively coupled to the movable part (35) of the further contact only in the direction towards the operating position.

Description

Ein elektromagnetisches Relais mit den im ersten Teil des Anspruchs 1 angegebenen Merkmalen ist aus DE-A-196 00 314 bekannt.An electromagnetic relay with those in the first part of the claim 1 features specified is known from DE-A-196 00 314.

Derartige Relais mit zwangsgeführten Kontakten haben die Aufgabe, einen zu schaltenden Stromkreis, etwa den Versorgungsstromkreis von Werkzeugmaschinen, Toren, Feuerungsanlagen oder medizinischen Geräten sicher zu trennen. Dazu werden die bei dem bekannten Relais vorhandenen beiden Schließer in dem zu schaltenden Stromkreis mit den Kontakten eines zweiten Relais in Serie angeordnet. Kann einer der Schließer, etwa infolge Kontaktverschweißung, nicht öffnen, so bleibt der zweite Schließer immer noch funktionsfähig und kann den Stromkreis immer noch unterbrechen. Zur Erkennung dieses Fehlers dient ein bei dem bekannten Relais vorgesehener Öffner, wobei eine Betätigungsanordnung dafür sorgt, daß der Öffner nur dann in seine geschlossene Ruhestellung zurückkehren kann, wenn beide Schließer öffnen.Such relays with positively driven contacts have the task a circuit to be switched, such as the supply circuit of Machine tools, gates, furnaces or medical devices sure to separate. These are the existing in the known relay two NO contacts in the circuit to be switched with the contacts a second relay arranged in series. Can one of the NO, about due to contact welding, do not open, so the second closer remains still functional and can still break the circuit. To detect this error is used in the known relay provided opener, wherein an actuating arrangement ensures that the Opener can only return to its closed rest position, when both normally open.

Die Betätigungsanordnung des bekannten Relais besteht aus zwei parallel zueinander bewegbaren Bauteilen, die jeweils mit seitlichen Vorsprüngen an den bewegbaren Teilen angreifen, und von denen der eine vom Relaisanker angetrieben wird, während der andere als Zwangsführer ausgebildet ist. Die Anordnung arbeitet nur dann ordnungsgemäß, wenn die beiden Bauteile der Betätigungsanordnung exakt aufeinander abgestimmt sind und mit ihren seitlichen Vorsprüngen einerseits eine Mitnahme der jeweiligen bewegbaren Teile sicherstellen und andererseits genügend Spiel lassen, um die Mitnahme der bewegbaren Teile durch die seitlichen Vorsprünge des jeweils anderen bewegbaren Bauteils nicht zu behindern.The actuating arrangement of the known relay consists of two parallel to each other movable components, each with lateral projections attack on the moving parts, and one of which Relay armature is driven, while the other is designed as a forcible guide is. The arrangement works properly only if the two components of the actuator assembly matched exactly are and with their lateral projections on the one hand entrainment of the respective ensure moving parts and on the other hand enough play Let go of the entrainment of the moving parts by the side projections the other movable member does not hinder.

Der Erfindung liegt die generelle Aufgabe zugrunde, Nachteile, wie sie bei vergleichbaren elektromagnetischen Relais nach dem Stand der Technik auftreten, mindestens teilweise zu beseitigen. Eine speziellere Aufgabe der Erfindung kann darin gesehen werden, ein elektromagnetisches Relais zu schaffen, das die gleiche Funktion wie das oben erläuterte bekannte Relais mit einfacherem Aufbau erreicht.The invention is based on the general object, disadvantages, such as in comparable electromagnetic relays according to the state of Technique occur, at least partially eliminate. A more specific task The invention can be seen in an electromagnetic To provide relay, the same function as the above-known known Relay with a simpler structure achieved.

Die erfindungsgemäße Lösung dieser Aufgabe ist im Anspruch 1 gekennzeichnet. Danach sind wenigstens zwei in ihrer Funktion gleiche Betätiger vorgesehen, die jeweils nur mit einem Schließer und dem gleichen Öffner zusammenarbeiten. Jeder einzelne Betätiger braucht auf den anderen nicht-zugeordneten Schließer keine Rücksicht zu nehmen, so daß seine Form weniger kritisch ist als beim Stand der Technik. Daraus resultieren größere Toleranzfreundlichkeit und höhere Funktionssicherheit.The inventive solution to this problem is characterized in claim 1. After that, at least two are in their function the same actuator provided, each with only one NO contact and the same Opener work together. Every single actuator needs the other unassigned NO to take no account, so that his Form is less critical than in the prior art. This results greater tolerance-friendliness and higher functional reliability.

Die Weiterbildung der Erfindung nach Anspruch 2 führt zu einer weiteren Vereinfachung insofern, als zusätzliche Einrichtungen zur Rückstellung der Betätiger nicht erforderlich sind.The development of the invention according to claim 2 leads to another Simplification insofar as additional provisions the actuator is not required.

In der Ausgestaltung der Erfindung nach Anspruch 3 ergibt sich eine kompakte und leichte Gestaltung der Betätigungsanordnung.In the embodiment of the invention according to claim 3, there is a compact and lightweight design of the actuator assembly.

Die Maßnahme des Anspruchs 4 ist für die Funktionssicherheit von Vorteil.The measure of claim 4 is for the reliability of Advantage.

A preferred embodiment of the invention will be explained below with reference to the drawings. It shows
FIG. 1
the contact system of an electromagnetic relay with removed actuators,
FIG. 2
the same contact system with built-in actuators in the rest position of the relay, wherein for clarity also coil, core and armature of the relay are shown,
FIG. 3
the contact system in working position of the relay, and
FIG. 4
the contact system is in the rest position of the relay, whereby one of the normally open contacts has not been opened due to welding and the positively driven opener has not closed.

Gemäß Figur 1 umfaßt die Kontaktanordnung zwei Schließer 10 und 20, einen Öffner 30 und zwei Betätiger 40, 50.According to FIG. 1, the contact arrangement comprises two make contacts 10 and 20, one opener 30 and two actuators 40, 50 .

Der Schließer 10 besteht aus einem Festkontakt 11 mit zwei Kontaktstücken 12, 13 und einem Anschlußteil 14 sowie einer Kontaktfeder 15, die an ihrem einen Ende an einem Anschlußteil 16 befestigt ist und an ihrem anderen, freien Ende zwei Kontaktstücke 17, 18 trägt, die mit den Kontaktstücken 12, 13 des Festkontakts 11 zusammenarbeiten.The shutter 10 consists of a fixed contact 11 with two contact pieces 12, 13 and a connecting part 14 and a contact spring 15 which is attached at its one end to a connecting part 16 and at its other, free end two contact pieces 17, 18 carries with the contact pieces 12, 13 of the fixed contact 11 work together.

Der Schließer 20 und der Öffner 30 sind identisch aufgebaut.The make 20 and the opener 30 are identical.

Die Kontaktfedern 15, 25 der beiden Schließer 10, 20 sind als Flexure-Kontaktfedern ausgebildet, so daß sich ihre Kontaktstücke in der Ruhelage, betrachtet ohne Betätiger, in einem Abstand von denen des jeweiligen Festkontakts 11, 21 befinden. Demgegenüber ist die Kontaktfeder 35 des Öffners 30 als Lift-off-Kontaktfeder ausgebildet, so daß ihre Kontaktstücke in der Ruhelage, betrachtet ohne Betätiger, an den Kontaktstücken des Festkontakts 31 anliegen. The contact springs 15, 25 of the two closer 10, 20 are formed as flexure-contact springs, so that their contact pieces in the rest position, considered without an actuator, at a distance from those of the respective fixed contact 11, 21 are located. In contrast, the contact spring 35 of the opener 30 is formed as a lift-off contact spring, so that their contact pieces in the rest position, considered without an actuator, bear against the contact pieces of the fixed contact 31 .

Der Betätiger 40 ist als insgesamt etwa U-förmige flache Schaltkarte gestaltet, wobei der rechte, nach unten ragende Schenkel 41 der U-Form einen nach unten offenen Schlitz 42 aufweist, der im eingebauten Zustand des Betätigers 40 (vergl. Figur 2 bis 4) die Kontaktfeder 15 des Schließers 10 beidseitig umgreift. Der Schlitz 42 ist mit zwei einander zugewandten Vorsprüngen 43, 44 versehen, die an beiden Seiten der Kontaktfeder 15 spielarm anliegen.The actuator 40 is designed as a total of approximately U-shaped flat circuit board, wherein the right, downwardly projecting leg 41 of the U-shape has a downwardly open slot 42 which in the installed state of the actuator 40 (see Fig. 2 to 4) the contact spring 15 of the closer 10 engages on both sides. The slot 42 is provided with two projections 43, 44 facing each other, which abut on both sides of the contact spring 15 play.

Der nach unten ragende linke Schenkel 45 weist einen dem rechten Schenkel 41 zugewandten Vorsprung 46 auf, der gemäß Figur 3 und 4 an der linken Seitenfläche der Kontaktfeder 35 des Öffners 30 anliegt.The downwardly projecting left leg 45 has a right leg 41 facing the projection 46 which rests according to Figures 3 and 4 on the left side surface of the contact spring 35 of the opener 30 .

Der Betätiger 50 ist mit dem Betätiger 40 im wesentlichen baugleich, wobei lediglich der Abstand zwischen den beiden Schenkeln 51, 55 voneinander geringer ist. Im eingebauten Zustand umgreift der Schlitz 52 die Kontaktfeder 25 des Schließers 20, wobei die beiden Vorsprünge 53, 54 an den Seitenflächen der Kontaktfeder 25 spielarm anliegen, während der Vorsprung 56 des linken Schenkels 55 an der linken Seitenfläche der Kontaktfeder 35 des Öffners 30 anliegt.The actuator 50 is substantially identical to the actuator 40 , wherein only the distance between the two legs 51, 55 is smaller from each other. When installed, the slot 52 engages around the contact spring 25 of the shutter 20, wherein the two projections 53, 54 rest against the side surfaces of the contact spring 25 play, while the projection 56 of the left leg 55 abuts the left side surface of the contact spring 35 of the opener 30 .

Wie in Figur 2 gezeigt, sind die beiden Betätiger 40, 50 dicht nebeneinander angeordnet, wobei ihre linken Stirnflächen, die in der in Figur 2 gezeigten Ruhestellung miteinander fluchten, zur Anlage am Anker 60 eines hier als monostabil angenommenen Relais dienen. Von dem Relais sind in Figur 2 außer dem Anker 60 die Spule 61 samt Spulenanschlüssen 62 und der die Spule 61 durchsetzende Kern 63 mit nach oben ragenden, mit dem Anker 60 zusammenwirkenden Polschuhen 64 gezeigt. In Figur 2 ist angenommen, daß sich das Relais in Ruhestellung befindet, so daß die Schließer 10, 20 geöffnet sind und der Öffner 30 geschlossen ist.As shown in Figure 2, the two actuators 40, 50 are arranged close to each other, with their left end faces, which are aligned in the rest position shown in Figure 2, to rest against the armature 60 of a here assumed as monostable relay. In addition to the armature 60, the coil 61 and the coil terminals 62 and the core 63 penetrating the coil 61 are shown in FIG. 2 with the pole shoes 64 projecting upwards and interacting with the armature 60 . In Figure 2 it is assumed that the relay is in the rest position, so that the closer 10, 20 are open and the opener 30 is closed.

Zieht das Relais an, so schwenkt der Anker 60 gegen den Uhrzeigersinn und übt auf beide Betätiger 40, 50 eine in Figur 2 nach rechts gerichtete Kraft aus. Die Betätiger 40 und 50 bewegen sich dabei in die in Figur 3 gezeigte Stellung, in der die beiden Schließer 10, 20 geschlossen sind und der Öffner 30 geöffnet ist.When the relay picks up, the armature 60 pivots counterclockwise and exerts on both actuators 40, 50 a force directed to the right in FIG. The actuators 40 and 50 move in the position shown in Figure 3, in which the two closer 10, 20 are closed and the opener 30 is opened.

In der Darstellung nach Figur 4 ist angenommen, daß das Relais abgefallen und der Anker in seine Ruhestellung zurückgekehrt ist, der Schließer 10 jedoch verschweißt hat. In dieser Stellung ist der Betätiger 50 durch den geöffneten Schließer 20 in seine Ausgangsstellung zurückgekehrt, während der Betätiger 40 durch den noch in der geschlossenen Stellung befindlichen, verschweißten Schließer 10 in seiner ausgelenkten Stellung festgehalten wird. Der linke Schenkel 45 des Betätigers 40 hält in diesem Fall die Kontaktfeder 35 des Öffners 30 in der geöffneten Stellung, während sich der linke Schenkel 55 des Betätigers 50 von der Kontaktfeder 35 weg bewegt hat.In the illustration of Figure 4 it is assumed that the relay has dropped and the armature has returned to its rest position, the closer 10 has, however, welded. In this position, the actuator 50 is returned by the open closer 20 in its initial position, while the actuator 40 is held by the still in the closed position, welded normally open 10 in its deflected position. The left leg 45 of the actuator 40 holds in this case, the contact spring 35 of the opener 30 in the open position, while the left leg 55 of the actuator 50 has moved away from the contact spring 35 .

Die gleiche Funktion würde sich ergeben, wenn der Schließer 20 verschweißt und der Schließer 10 bei abfallendem Relais öffnet. In diesem Fall würde die Kontaktfeder 35 des Öffners 30 durch den linken Schenkel 55 des Betätigers 50 in der in Figur 4 gezeigten geöffneten Stellung festgehalten.The same function would result if the closer 20 is welded and the closer 10 opens when the relay drops. In this case, the contact spring 35 of the opener 30 would be held by the left leg 55 of the actuator 50 in the open position shown in Figure 4.

In dem obigen Ausführungsbeispiel sind die Betätiger 40, 50 so gestaltet, daß sie mit den Kontaktfedern 15, 25 des jeweils zugeordneten Schließers 10, 20 in beiden Richtungen zwangsgeführt gekoppelt sind. Mit anderen Worten werden die Kontaktfedern 15, 25 bei anziehendem Relais durch die Betätiger 40, 50 entgegen ihrer Federvorspannung in die geschlossene Stellung geführt, während das Öffnen der Schließer 10, 20 durch die Rückstellkraft der Federn 15 bzw. 25 erfolgt.In the above embodiment, the actuators 40, 50 are designed such that they are forcibly coupled with the contact springs 15, 25 of the respectively associated closer 10, 20 in both directions. In other words, the contact springs 15, 25 are guided in attracting relay by the actuator 40, 50 against its spring bias in the closed position, while the opening of the closer 10, 20 takes place by the restoring force of the springs 15 and 25 respectively.

Gemäß einer nicht dargestellten Variante ist es auch möglich, mehr als zwei Schließer mit einer entsprechenden Anzahl von Betätigern vorzusehen und funktionsmäßig mit dem gleichen Öffner zu koppeln.According to a variant, not shown, it is also possible more to provide as two normally open with a corresponding number of actuators and to functionally couple with the same break contact.

Ferner ist in dem obigen Ausführungsbeispiel angenommen, daß der dritte Kontakt 30 als Öffner gestaltet ist. Es wäre auch möglich, dieser Kontakt als Schließer auszubilden. In diesem Fall würde immer dann, wenn einer der beiden Schließer 10, 20 verschweißt, der dritte Kontakt 30 nicht mehr öffnen können. Auch diese Funktion ließe sich zum Erkennen eines Verschweißungszustandes heranziehen.Further, in the above embodiment, it is assumed that the third contact 30 is configured as an opener. It would also be possible to form this contact as normally open. In this case, whenever one of the two closer 10, 20 welded, the third contact 30 would not be able to open. This function could also be used to detect a welding condition.
