Description

Die Erfindung betrifft ein elektromagnetisches Relais mit einem Grundkörper, auf dem ein Elektromagnetsystem mit Spule, Kern, Joch und Anker angeordnet und in dem im Abstand zum Magnetsystem eine Kontaktanordnung mit mindestens einem Gegenkontaktelement und mindestens einer beweglichen Kontaktfeder verankert ist, wobei die Kontaktfeder einen mit dem oder den Gegenkontaktelementen zusammenwirkenden Kontaktabschnitt, einen im Grundkörper verankerten Befestigungsabschnitt und einen Betätigungsabschnitt aufweist, der mit einem die Ankerbewegung auf die Kontaktfeder übertragenden, aus Isolationsmaterial bestehendem Betätigungselement in Verbindung steht.The invention relates to an electromagnetic relay with a base body, on which an electromagnetic system with a coil, core, yoke and armature is arranged and in which a contact arrangement with at least one mating contact element and at least one movable contact spring is anchored at a distance from the magnet system, the contact spring being one with the or the contact section interacting with the counter-contact elements, has a fastening section anchored in the base body and an actuating section which is connected to an actuating element made of insulation material and transmitting the armature movement to the contact spring.

Ein solches Relais ist beispielsweise in der EP 0 363 976 A1 beschrieben. Um die Isolationsforderungen zwischen Magnetsystem und Kontaktanordnung zu erfüllen, sind bei diesem Relais der Anker und die Kontaktanordnung an entgegengesetzten Enden der Spule im Grundkörper angeordnet, wobei die Bewegung des Ankers mittels eines langen Schiebers auf die Kontaktfeder übertragen wird. Dieser Schieber ist parallel zur Spule geführt, wodurch das Gehäuse größere Abmessungen haben muß.Such a relay is described for example in EP 0 363 976 A1. In order to meet the insulation requirements between the magnet system and the contact arrangement, in this relay the armature and the contact arrangement are arranged on opposite ends of the coil in the base body, the movement of the armature being transmitted to the contact spring by means of a long slide. This slide is guided parallel to the coil, which means that the housing must have larger dimensions.

Ein Relais, bei dem der Anker und die Kontaktanordnung am selben Ende der Spule angebracht sind, wobei sich der Anker zwischen Spule und Kontaktanordnung befindet, ist aus der DE 8701349 U bekannt. Bei diesem Relais wird kein Schieber verwendet, so daß eine kleinere Bauform erreicht wird, jedoch sind hier Kontaktfeder und Anker leitend miteinander verbunden, da die Isolationsforderungen durch Umspritzen der Wicklung erfüllt werden.A relay in which the armature and the contact arrangement are attached to the same end of the coil, the armature being located between the coil and the contact arrangement, is known from DE 8701349 U. This relay does not use a slide, so that a smaller design is achieved, but here the contact spring and armature are conductively connected to one another, since the insulation requirements are met by overmolding the winding.

Aufgabe der Erfindung ist es somit, ein Relais der eingangs genannten Art so zu gestalten, daß bei möglichst geringem Bauvolumen die vorgeschriebenen Luft- und Kriechstreckenforderungen erfüllt werden, ohne daß die Spule besonders gestaltet werden muß.The object of the invention is therefore to design a relay of the type mentioned in such a way that the prescribed clearance and creepage distance requirements are met with the smallest possible construction volume, without the coil having to be specially designed.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Betätigungselement einen als Kappe ausgebildeten, trichterförmig sich öffnenden Abschirmabschnitt und einen mit dem Anker in Verbindung stehenden Schiebeabschnitt aufweist, wobei der Abschirmabschnitt über den Betätigungsabschnitt der Kontaktfeder gestülpt ist.The object is achieved in that the actuating element has a cap-shaped, funnel-shaped shielding section and a sliding section connected to the armature, the shielding section being slipped over the actuating section of the contact spring.

Zweckmäßigerweise ist dabei der Grundkörper mit einer die Anschlußseite bildenden Bodenplatte und mit einer zur Trennung der Bereiche für das Magnetsystem und die Kontaktanordnung vorgesehenen U-förmigen Zwischenwand ausgebildet, wobei diese am Grundkörper angeformt sein kann.The base body is expediently formed with a base plate forming the connection side and with a U-shaped intermediate wall provided for separating the areas for the magnet system and the contact arrangement, it being possible for this to be integrally formed on the base body.

In einer möglichen Ausführungsform des erfindungsgemäßen Relais weist die der Anschlußseite zugewandte Seitenwand des Abschirmabschnitts des Betätigungselements eine Öffnung auf, wobei der Abschirmabschnitt in einer senkrecht zur Bodenplatte verlaufenden Richtung von dieser Seite her über den Betätigungsabschnitt der Kontaktfeder gestülpt ist. Der Abschirmabschnitt umschließt den Betätigungsabschnitt der Kontaktfeder zwar nicht auf vier Seiten, jedoch kann er trotzdem so gestaltet werden, daß die nötigen Luft- und Kriechstrecken eingehalten werden.In a possible embodiment of the relay according to the invention, the side wall of the shielding section of the actuating element facing the connection side has an opening, the shielding section being slipped over the actuating section of the contact spring from this side in a direction perpendicular to the base plate. The shielding section does not enclose the actuating section of the contact spring on four sides, but it can nevertheless be designed in such a way that the necessary air and creepage distances are maintained.

Eine mögliche Realisierung der Verbindung zwischen dem Schiebeabschnitt des Betätigungselementes und dem Anker kann dadurch erreicht werden, daß der Schiebeabschnitt hakenförmig ausgebildet ist und über einen am freien Ende des Ankers angeformten Zapfen greift. Es ist aber auch möglich, den Schiebeabschnitt trichterförmig sich öffnend auszubilden und ihn über einen am Anker ausgeformten Zapfen zu stülpen. Weiterhin ist es möglich, das aus einem Abschirmabschnitt und einem plattenförmigen Schiebeabschnitt gebildete Betätigungselement zweiteilig auszuführen, wobei an beiden Teilen sowie am Anker Verbindungselemente vorgesehen sind, die ein Zusammenwirken des Abschirmabschnitts mit dem Schiebeabschnitt sowie des Schiebeabschnitts mit dem Anker ermöglichen. Vorzugsweise sind dabei am Abschirmabschnitt ein Zapfen angeformt und am Schiebeabschnitt Ausnehmungen vorgesehen, in die der Zapfen des Abschirmabschnitts sowie ein am freien Ende des Ankers angeformter Zapfen eingreifen. Es ist jedoch auch möglich sowohl am Abschirmabschnitt als auch am Anker Ausnehmungen vorzusehen, in die am Schiebeabschnitt angeformte Zapfen eingreifen.A possible realization of the connection between the sliding section of the actuating element and the armature can be achieved in that the sliding section is hook-shaped and engages over a pin formed on the free end of the armature. However, it is also possible to design the sliding section in a funnel shape and to place it over a pin formed on the anchor. Furthermore, it is possible to design the actuating element, which is formed from a shielding section and a plate-shaped sliding section, in two parts, connecting elements being provided on both parts and on the armature, which enable the shielding section to interact with the sliding section and the sliding section with the armature. A pin is preferably formed on the shielding section and recesses are provided on the sliding section, into which the pin of the shielding section and a pin formed on the free end of the armature engage. However, it is also possible to provide recesses both on the shielding section and on the armature, into which pins formed on the sliding section engage.

Die erfindungsgemäße Gestaltung läßt sich besonders günstig anwenden bei einem Relais bei dem der Anker an der Stirnseite der Spule zwischen der Spule und der Kontaktanordnung angebracht ist. Dabei kann die Bewegungsebene des Ankers der Kontaktfeder und des Betätigungselements sowohl senkrecht als auch parallel zur Abschlußseite verlaufen. In einer vorteilhaften Ausführungsform ist die Kontaktfeder, wie bereits aus der DE 8701349 U bekannt, mit einem U-förmigen und einem L-förmigen Teil gebildet, wobei ein Schenkel des U-förmigen Teils den Kontaktabschnitt und der kurze Schenkel des L-förmigen Teils den Befestigungsabschnitt bilden und wobei der andere Schenkel des U-förmigen Teils mit dem langen Schenkel des L-förmigen Teils verbunden ist und den Betätigungsabschnitt bildet.The design according to the invention can be used particularly advantageously in a relay in which the armature is attached to the end face of the coil between the coil and the contact arrangement. The plane of movement of the armature of the contact spring and of the actuating element can run both perpendicularly and parallel to the end side. In an advantageous embodiment, as already known from DE 8701349 U, the contact spring is formed with a U-shaped and an L-shaped part, with one leg of the U-shaped part the contact section and the short leg of the L-shaped part the Form fastening section and wherein the other leg of the U-shaped part is connected to the long leg of the L-shaped part and forms the actuating section.

Zum Schutz des Relais ist eine Kappe mit einer zwischen Magnetsystem und Kontaktanordnung ragenden Zwischenwand vorgesehen. Durch diese Zwischenwand wird die Isolation zwischen Magnetsystem und Kontaktanordnung zusätzlich erhöht.To protect the relay, a cap is provided with an intermediate wall projecting between the magnet system and the contact arrangement. This partition further increases the insulation between the magnet system and the contact arrangement.

In weiterer Ausgestaltung der Erfindung sind im Innern des Abschirmabschnitts Vorsprünge vorgesehen, zwischen denen der Betätigungsabschnitt der Kontaktfeder gelagert ist, wodurch eine sichere Verbindung zwischen Anker und Kontaktfeder gewährleistet wird.In a further embodiment of the invention, projections are provided in the interior of the shielding section, between which the actuating section of the contact spring is mounted, thereby ensuring a secure connection between the armature and the contact spring.

Das in den Figuren 1 und 2 gezeigte Relais besitzt einen die Anschlußseite bildenden Grundkörper 1, auf dem ein Magnetsystem 2 und eine Kontaktanordnung 7 angeordnet sind. Das Magnetsystem 2 ist mit einer Spule 3, einem Kern 4, einem winkelförmigen Joch 5 und einem mittels einer Feder 22 am Joch 5 befestigten Anker 6 gebildet, wobei der Anker 6 stirnseitig vor der Spule zwischen Spule 3 und Kontaktanordnung 7 angeordnet ist.The relay shown in Figures 1 and 2 has a base body 1 forming the connection side, on which a magnet system 2 and a contact arrangement 7 are arranged. The magnet system 2 is formed with a coil 3, a core 4, an angular yoke 5 and an armature 6 fastened to the yoke 5 by means of a spring 22, the armature 6 being arranged on the end face in front of the coil between the coil 3 and the contact arrangement 7.

Die Kontaktanordnung 7 besteht aus zwei Gegenkontaktelementen 8a und 8b und einer beweglichen Kontaktfeder 9, die im Grundkörper 1 in Schlitzen oder Durchbrüchen verankert und zur Anschlußseite geführt sind. Die Kontaktfeder 9 besteht ihrerseits aus einem Kontaktabschnitt 9a, der in der dargestellten Ruhestellung mit dem Gegenkontaktelement 8a in Kontakt ist, einem im Grundkörper 1 verankerten Befestigungsabschnitt 9b und einem Betätigungsabschnitt 9c. Über den Betätigungsabschnitt 9c ist ein als Kappe ausgebildeter, trichterförmig sich öffnender Abschirmabschnitt 10a eines Betätigungselements 10 gestülpt. An diesem Betätigungsabschnitt 10a ist ein Schiebeabschnitt 10b angeformt, der hakenförmig ausgebildet ist und über einen am freien Ende des Ankers 6 angeformten Zapfen 12 greift, wodurch die Bewegung des Ankers 6 auf die Kontaktfeder 9 übertragen wird.The contact arrangement 7 consists of two mating contact elements 8a and 8b and a movable contact spring 9, which are anchored in the base body 1 in slots or openings and guided to the connection side. The contact spring 9 in turn consists of a contact section 9a, which in the rest position shown is in contact with the mating contact element 8a, a fastening section 9b anchored in the base body 1 and an actuating section 9c. A funnel-shaped shielding section 10a of an actuating element 10, which is designed as a cap, is placed over the actuating section 9c. A sliding section 10b is formed on this actuating section 10a, which is hook-shaped and engages over a pin 12 formed on the free end of the armature 6, whereby the movement of the armature 6 is transmitted to the contact spring 9.

Am Grundkörper 1 ist eine U-förmige Zwischenwand 11 angeformt, die zur Isolierung der Kontaktanordnung 7 vom Magnetsystem 2 dient und über die der Schiebeabschnitt 10b des Betätigungselements 10 ragt. Bei dieser in Fig. 1 und 2 gezeigten Ausführung des erfindungsgemäßen Relais ist der Abschirmabschnitt 10a des Betätigungselements 10 an seiner der Anschlußseite zugewandten Seite geöffnet und wird in einer senkrecht zur Anschlußseite verlaufenden Richtung über den Betätigungsabschnitt 9c gestülpt.A U-shaped intermediate wall 11 is formed on the base body 1, which serves to isolate the contact arrangement 7 from the magnet system 2 and over which the sliding section 10b of the actuating element 10 projects. In this embodiment of the relay according to the invention shown in FIGS. 1 and 2, the shielding section 10a of the actuating element 10 is open on its side facing the connection side and is placed over the actuation section 9c in a direction perpendicular to the connection side.

Es ist aber auch möglich, den Abschirmabschnitt 10c auf allen vier Seiten geschlossen auszuführen, wodurch er aber in einer parallel zur Anschlußseite verlaufenden Richtung über den Betätigungsabschnitt 9c gestülpt werden muß. Dabei kann in der U-förmigen Zwischenwand 11 eine Aussparung vorgesehen sein, durch die der hakenförmige Schiebeabschnitt 10b geführt wird.However, it is also possible to make the shielding section 10c closed on all four sides, as a result of which it must be placed over the actuating section 9c in a direction running parallel to the connection side. A recess can be provided in the U-shaped partition 11 through which the hook-shaped sliding section 10b is guided.

Im Bodenbereich des als Kappe ausgebildeten Abschirmabschnitts 10b sind Noppen 10c und 10d ausgebildet, zwischen denen der Betätigungsabschnitt 9c der Kontaktfeder 9 gehalten wird.In the bottom area of the shielding section 10b formed as a cap, knobs 10c and 10d are formed, between which the actuating section 9c of the contact spring 9 is held.

Auf den Grundkörper 1 mit montiertem Magnetsystem 2 und Kontaktanordnung 7 wird eine mit Zwischenwänden 21a,21b und 21c versehene Kappe 20 gesteckt. Die Zwischenwände 21a und 21b haben die Aufgabe, die Gegenkontaktelemente 8a und 8b gegen den Befestigungsabschnitt 9b und den Betätigungsabschnitt 9c der Kontaktfeder 9 abzuschirmen, während die Zwischenwand 21c zusammen mit dem Betätigungselement 10 und der U-förmigen Zwischenwand 11 zur Isolation des Betätigungsabschnitts 9c vom Anker 6 dient. Auf diese Weise sind alle Luft- und Kriechstrecken zwischen der Kontaktanordnung 7 und dem Magnetsystem 2 genügend groß, um die VDE-Forderungen zu erfüllen.A cap 20 provided with intermediate walls 21a, 21b and 21c is placed on the base body 1 with the magnet system 2 and the contact arrangement 7 mounted. The intermediate walls 21a and 21b have the task of shielding the mating contact elements 8a and 8b against the fastening section 9b and the actuating section 9c of the contact spring 9, while the intermediate wall 21c together with the actuating element 10 and the U-shaped intermediate wall 11 for isolating the actuating section 9c from the armature 6 serves. In this way, all clearances and creepage distances between the contact arrangement 7 and the magnet system 2 are large enough to meet the VDE requirements.

Das in den Figuren 3 und 4 dargestellte Relais realisiert eine weitere mögliche Ausführungsform des erfindungsgemäßen Relais, wobei hier die Ebene, in der sich der Anker 6 und die Kontaktfeder 9 bewegen, senkrecht zur Anschlußseite liegt und somit gegenüber dem in den Figuren 1 und 2 dargestellten Relais um 90° gedreht ist. Gleichwirkende Teile sind hier mit gleichen Bezugszeichen wie in den Figuren 1 und 2 versehen. So ist auch hier auf einem Grundkörper 1 ein Magnetsystem 2, bestehend aus einer Spule 3, einem Kern 4, einem Joch 5 und einem Anker 6, angeordnet. Der Anker 6 ist an seinem freien Ende mit einem Zapfen 17 versehen, der in die trichterförmige Öffnung des Schiebeabschnitts 23 eines Betätigungselements 10 ragt. Das Betätigungselement 10 hat außerdem einen als Kappe ausgebildeten, trichterförmig sich öffnenden Abschirmabschnitt 10a, der über den Betätigungsabschnitt 9c einer Kontaktfeder 9 gestülpt ist. Zur Isolation zwischen dem Magnetsystem 2 und einer Kontaktanordnung 7 dienen auch hier, zusammen mit dem Abschirmabschnitt 10a, eine U-förmige Zwischenwand 11 und Zwischenwände 24a bis 24d, die an einer Kappe 20 angeformt sind. Die Zwischenwand 24b ist in Figur 4 gebrochen dargestellt; sie verläuft bezüglich der Anschlußseite oberhalb der Kontaktanordnung 7, wie in Figur 3 zu sehen ist. Die U-förmige Zwischenwand 11 hat eine seitliche Aussparung, durch die das Betätigungselement 10 gesteckt werden kann.The relay shown in Figures 3 and 4 realizes a further possible embodiment of the relay according to the invention, the plane in which the armature 6 and the contact spring 9 move, is perpendicular to the connection side and thus opposite to that shown in Figures 1 and 2 Relay is rotated by 90 °. Parts having the same effect are provided here with the same reference symbols as in FIGS. 1 and 2. A magnet system 2, consisting of a coil 3, a core 4, a yoke 5 and an armature 6, is also arranged on a base body 1 here. The armature 6 is provided at its free end with a pin 17 which projects into the funnel-shaped opening of the sliding section 23 of an actuating element 10. The actuating element 10 also has a cap-shaped, funnel-shaped shielding section 10a which is slipped over the actuating section 9c of a contact spring 9. A U-shaped intermediate wall 11 and intermediate walls 24a to 24d, which are integrally formed on a cap 20, also serve here for insulation between the magnet system 2 and a contact arrangement 7, together with the shielding section 10a. The intermediate wall 24b is shown broken in Figure 4; it runs above the contact arrangement 7 with respect to the connection side, as can be seen in FIG. The U-shaped partition 11 has a lateral recess through which the actuating element 10 can be inserted.

Eine weitere mögliche Ausführungsform des Betätigungselements 10 ist in Figur 5 dargestellt. Über die Kontaktfeder 9 ist ein trichterförmig sich öffnender Abschirmabschnitt 13 gestülpt, an dem ein Zapfen 15 angeformt ist.
