Abstract

The electromagnetic relay is constructed as a monostable or as a bistable relay with a rotatable tumbler switch. In both forms, there is a switch spring, that is adapted to the anchor, resolvably fastened in the anchor. Thereby an improved mass moment of inertia results, as well as improved switch stop of the relay, and an improved shock and vibration resistance. The switch spring has a sprayed-on synthetic footpiece which is fastened resolvably, turnably and pushably in an adapted opening of the anchor.

Description

Die Erfindung betrifft ein elektromagnetisches Relais, bestehend aus einem Antriebssystem mit Erregerspule und Jochblechen, die mit einem schwenkbaren Anker einen geschlossenen magnetischen Kreis bilden, wobei der Anker mit einer Umschaltfeder verbunden ist, dessen Kontakte mit feststehenden Kontakten am Federbock zusammenwirken.The invention relates to an electromagnetic relay, consisting of a drive system with excitation coil and yoke plates, which form a closed magnetic circuit with a pivotable armature, the armature being connected to a changeover spring, the contacts of which cooperate with fixed contacts on the spring bracket.

Ein eingangs genanntes Relais ist beispielsweise mit der auf den gleichen Anmelder zurückgehenden DE-OS 30 21 184 bekannt geworden. Dieses bekannte Relais ist bistabil ausgebildet und der Anker ist als bewegliche Wippe ausgestaltet. Die an der Wippe angeordnete Umschaltfeder zusammen mit der Wippe selbst bildet eine beträchtliche Masse. Der Massenschwerpunkt der gesamten Anordnung befindet sich nicht im Drehpunkt, sondern entfernt davon, wodurch ein erhöhtes Massenträgheitsmoment entsteht und das Schaltverhalten des Relais optimierbar ist.A relay mentioned at the outset has become known, for example, from DE-OS 30 21 184, which goes back to the same applicant. This known relay is bistable and the armature is designed as a movable rocker. The changeover spring arranged on the rocker together with the rocker itself forms a considerable mass. The center of gravity of the entire arrangement is not at the fulcrum, but at a distance from it, which results in an increased moment of inertia and the switching behavior of the relay can be optimized.

Die vorliegende Erfindung hat sich die Aufgabe gestellt, ein Relais der eingangs genannten Art so weiterzubilden, daß die bewegte Masse wesentlich verringert werden kann.The present invention has for its object to develop a relay of the type mentioned so that the moving mass can be significantly reduced.

Zur Lösung der gestellten Aufgabe ist die Erfindung dadurch gekennzeichnet, daß die Umschaltfeder ein angespritztes Fußstück aus Kunststoff aufweist, welches in einer zugeordneten öffnung des Ankers verdrehungs-und verschiebungsgesichert lösbar befestigt ist.To achieve the object, the invention is characterized in that the changeover spring has an injection-molded plastic foot piece, which is detachably fastened in an assigned opening of the armature so as to be secured against rotation and displacement.

Wesentliches Merkmal der vorliegenden Erfindung ist also die Auswechselbarkeit der Umschaltfeder im Bereich des Ankers. Die Umschaltfeder ist hierbei mit einer radialen und axialen Verschiebungssicherung im Anker gesichert. Die vorliegende Erfindung ist also sowohl für monostabile als auch für bistabile Relais einsetzbar, d.h., der Anker kann aus einem Metallteil bestehen (z.B. für ein monostabiles Relais), während in der Ausführung eines bistabilen Relais der Anker als schwenkbare Wippe ausgebildet ist, die zwischen einander gleichen Ankerplatten einen Permanentmagneten aufweist. Mit der lösbaren Befestigung der Umschaltfeder im Bereich des Ankers oder der Wippe wird der wesentliche Vorteil erzielt, daß der Drehpunkt nahe an den Massenschwerpunkt verlegt wird und das Schaltverhalten des Relais hierdurch günstig beeinflusst wird. Die lösbare Befestigung der Umschaltfeder im Bereich des Ankers oder der Wippe kann hierbei auf verschiedenartige Weise gelöst werden. Wichtig ist nur, daß die Umschaltfeder jederzeit auswechselbar ist und daß eine radiale und axiale Verschiebungssicherung gewährleistet ist. Hierdurch ist es beispielsweise möglich, ein Relais baukstenartig aufzubauen und eine Umschaltfeder besonderer Konstruktion gegen eine andere Umschaltfeder zu ersetzen.An essential feature of the present invention is therefore the interchangeability of the changeover spring in the area of the armature. The switchover spring is secured with a radial and axial displacement lock in the armature. The present invention can thus be used for both monostable and bistable relays, ie the armature can consist of a metal part (for example for a monostable relay), while in the embodiment of a bistable relay the armature is designed as a swiveling rocker which is between them same anchor plates has a permanent magnet. With the detachable fastening of the changeover spring in the area of the armature or the rocker, the essential advantage is achieved that the pivot point is moved close to the center of gravity and the switching behavior of the relay is thereby favorably influenced. The releasable attachment of the changeover spring in the area of the armature or the rocker can be solved in various ways. It is only important that the changeover spring can be replaced at any time and that radial and axial displacement protection is ensured. This makes it possible, for example, to construct a relay in a modular manner and to replace a changeover spring of a special design with another changeover spring.

Wichtig hierbei ist, daß die Umschaltfeder ein angespritztes Fußstück aus Kunststoff aufweist, welches in einer öffnung der Wippe radial und axial verschiebungsgesichert gelagert ist.It is important here that the change-over spring has an injection-molded plastic foot piece, which is mounted in an opening of the rocker so as to prevent radial and axial displacement.

Eine bevorzugte Ausführung einer radialen Verschiebungssicherung besteht nach dem Gegenstand des Anspruches 4 darin, daß am hinteren Ende des Fußstückes seitlich vorstehende Vorsprünge angeordnet sind, daß das Fußstück in der einen Verdrehungslage durch die öffnung des Ankers oder der Wippe passt und daß in der um 90° gedrehten Verdrehungslage das Fußstück mit seinen Vorsprüngen hinter zugeordnete Hinterschneidungen im Bereich der Platte, des Ankers oder der Wippe eingreift.A preferred embodiment of a radial anti-displacement device is according to the subject matter of claim 4 that laterally protruding projections are arranged at the rear end of the foot piece, that the foot piece fits in one rotational position through the opening of the armature or the rocker and that in the 90 ° rotated twist position the footpiece with its projections engages behind associated undercuts in the area of the plate, the anchor or the rocker.

Eine besondere Ausgestaltung einer axialen Verschiebungssicherung wird nach dem Gegenstand des Anspruches 5 dadurch gebildet, daß an der in die Öffnung eingreifenden Stirnseite des Fußstücks eine erste Ankerplatte angeordnet ist, die verschiebungsgesichert an der Rückseite der Platte der Wippe angeordnet ist, daß unterhalb der ersten Ankerplatte ein Permanentmagnet angeordnet ist, der seinerseits von einer zweiten Ankerplatte abgedeckt ist, die mittels von an den Seitenflächen der Wippe angeordneten Rastnasen axial verschiebungsgesichert und lösbar an der Wippe befestigt sind. Zur Demontage der Umschaltfeder muß also zunächst die von der Rastnase festgehaltene Ankerplatte aus der Wippe gelöst werden, um sonach den Permanentmagnet zu entfernen und um dann die an der Stirnseite des Fußstücks anliegende Ankerplatte zu entfernen. Erst dann kann das Fußstück der Umschaltfeder um ein kurzes Stück axial einwärts verschoben werden, gedreht werden, um sonach aus der öffnung der Wippe herausgezogen zu werden.A special embodiment of an axial displacement lock is formed according to the subject of claim 5 in that a first anchor plate is arranged on the end face of the foot piece engaging in the opening, which is arranged secured against displacement on the back of the plate of the rocker that below the first anchor plate Is arranged permanent magnet, which in turn is covered by a second anchor plate, which are axially secured against displacement and releasably attached to the rocker by means of locking lugs arranged on the side surfaces of the rocker. To dismantle the changeover spring, the anchor plate held by the locking lug must first be released from the rocker in order to remove the permanent magnet and then to remove the anchor plate resting on the end face of the foot piece. Only then can the foot of the changeover spring be moved axially inwards by a short distance, rotated, in order to be pulled out of the opening of the rocker.

Weitere Merkmale der Erfindung sind Gegenstand der übrigen Unteransprüche.Further features of the invention are the subject of the remaining subclaims.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

Das erfindungsgemässe Relais besteht aus einer Abdeckhaube 1 mit einem Federbock 2, der einen Kontaktträger 3 aufweist, der drei Stück Klemmschrauben 4 und drei Stück Hohlklemmen 5 aufweist. Der Kontaktträger 3 besteht an seinem oberen Teil aus einem gebogenen Metallbügel, der in einen feststehenden Kontakt 6 übergeht.The relay according to the invention consists of a cover 1 with a spring bracket 2, which has a contact carrier 3, which has three pieces of clamping screws 4 and three pieces of hollow terminals 5. The contact carrier 3 consists at its upper part of a bent metal bracket which merges into a fixed contact 6.

Es ist ferner ein weiterer Kontaktträger 7 vorhanden, der ebenfalls einen feststehenden Kontakt 8 aufweist.There is also a further contact carrier 7, which also has a fixed contact 8.

Ferner ist eine Umschaltfeder 9 vorhanden, die als Brückenkontakt ausgebildet ist, d.h. sie hat stets Kontakt zu einem feststehenden Mittenkontakt, die Brückenfeder ist am freien Ende eines Stanzteiles 10 angeordnet und sitzt mit ihrem Fußstück in einer Wippe 11, die schwenkbar in einer Lagerplatte 12, die am Magnetteil angenietet ist, befestigt ist.There is also a switching spring 9 which is designed as a bridge contact, i.e. it is always in contact with a fixed center contact, the bridge spring is arranged at the free end of a stamped part 10 and sits with its foot piece in a rocker 11 which is pivotally fastened in a bearing plate 12 which is riveted to the magnetic part.

Zur Stabilisierung des Gehäuses ist ein äußerer, umlaufender Bügel 13 aus Kunststoff vorgesehen. Im Gehäuse ist ferner eine Relaisspule 14 mit Anschlüssen 15 und 16 vorhanden. Die Relaisspule 14 wirkt auf zwei Jochbleche 17,38. Die Wippe 11 ist über eine Handhabe 18 verlängert und greift durch eine entsprechende Ausnehmung 19 in der Abdeckhaube 1 hindurch, so daß die handbetätigbar ist.To stabilize the housing, an outer, circumferential bracket 13 made of plastic is provided. In the housing there is also a relay coil 14 with connections 15 and 16. The relay coil 14 acts on two yoke plates 17.38. The rocker 11 is extended via a handle 18 and extends through a corresponding recess 19 in the cover 1, so that it can be operated manually.

Die Wippe besteht gemäss Figur 2 und 3 bevorzugt aus einem Kunststoffteil mit einer länglichen Platte 20, in die eine öffnung 21 eingelassen ist. In der Öffnung 21 sitzt die Umschaltfeder 9 mit einem aus Isoliermaterial bestehenden Fußstück 22. Wichtig hierbei ist, daß das Stanzteil 10 voll umfänglich von dem Kunststoffmaterial umgeben ist und die Umschaltfeder 9 durch eine Drehbewegung in die Ausnehmung 21 an der Wippe 11 eingebracht ist. Die Drehbewegung geht hierbei in Pfeilrichtung 23, und das Fußstück wird in der Art einer Bajonettkupplung in diese Ausnehmung eingesetzt. Die Ausnehmung ist hierbei mit einer Hinterschneidung 24 versehen, in welche das Fußstück 22 der Umschaltfeder eingreift. Die Hinterschneidung 24 ist in Figur 6 vergrößert dargestellt und wird dort noch näher dargestellt.According to FIGS. 2 and 3, the rocker preferably consists of a plastic part with an elongated plate 20 into which an opening 21 is embedded. In the opening 21, the changeover spring 9 is seated with a foot piece 22 made of insulating material. It is important here that the stamped part 10 is completely surrounded by the plastic material and the changeover spring 9 is introduced into the recess 21 on the rocker 11 by a rotary movement. The rotary movement is in the direction of arrow 23, and the foot piece is inserted into this recess in the manner of a bayonet coupling. The recess is provided with an undercut 24 in which the foot piece 22 of the changeover spring engages. The undercut 24 is shown enlarged in FIG. 6 and is shown in more detail there.

Die Wippe 11 besteht ferner aus zwei seitlichen Lagerarmen 25 und 26; an jedem Lagerarm sind nach außen ragende Lagerbolzen 27,28 angeordnet.The rocker 11 also consists of two lateral bearing arms 25 and 26; outwardly projecting bearing bolts 27, 28 are arranged on each bearing arm.

Ferner sind unten an jedem Lagerarm 25,26 verlängerte Rastnasen 29,30 angeordnet, deren Funktion noch später beschrieben wird. Zur axialen Sicherung des Fußstückes 22, damit es in Pfeilrichtung 31 nicht herausfällt, ist hinter dem Fußstück 22 im Bereich an der Rückseite der Lagerplatte 20 der Wippe 11 eine Ankerplatte 32 angeordnet, in der Bohrungen angeordnet sind, die auf entsprechend angeordneten Arretierstiften 33,34 der Platte 20 aufliegt. Ferner ist an der Rückseite der Lagerplatte 20 ein Permanent-Magnet 35 angebracht, der von der Rückseite wiederum durch eine doppel-T-förmige Ankerplatte 36 gehalten wird. Die Ankerplatten 32,36 sind genau gleich. Die Ankerplatte 36 wird rastend von den Rastnasen 29,30 der Wippe 11 gehalten. Damit wird der Magnet 35 und die erste Ankerplatte 32 axial gegen die Umschaltfeder 9 verspannt. Die Rastnasen 29,30 sind gemäss Figur 3 mit ihren Rastöffnungen auf die entsprechende Lagerplatte 36 aufgerastet. Ferner sind gemäss Figur 4 - 6 die Lagerbolzen 27,28 und die Hinterschneidung 24, im Bereich der Ausnehmung 21 erkennbar. In Fig. 7 und Fig. 8 ist die Umschaltfeder noch näher dargestellt. Wichtig ist, daß bei dem Fußstück 22 untere Vorsprünge 37 vorhanden sind, die bei einer Drehbewegung in die Hinterschneidungen 24, die kreisförmig im Bereich der Ausnehmung 21 angelegt sind, eingreifen. Hierdurch ist die gesamte Umschaltfeder gegen eine radiale Verdrehung gesichert und die axiale Verschiebungssicherung wird durch die dahinter angeordnete Lagerplatte 32 mit dem Magneten 35 und der weiteren Lagerplatte 36 bewirkt, die mit den Rastnasen 29,30 zusammenwirkt.Furthermore, 25, 26 are extended at the bottom of each bearing arm Arranged lugs 29,30, the function of which will be described later. To axially secure the foot piece 22 so that it does not fall out in the direction of the arrow 31, an anchor plate 32 is arranged behind the foot piece 22 in the area on the rear of the bearing plate 20 of the rocker 11, in which holes are arranged which are arranged on correspondingly arranged locking pins 33, 34 the plate 20 rests. Furthermore, a permanent magnet 35 is attached to the back of the bearing plate 20, which in turn is held by a double-T-shaped anchor plate 36 from the back. The anchor plates 32, 36 are exactly the same. The anchor plate 36 is held by the locking lugs 29, 30 of the rocker 11. The magnet 35 and the first armature plate 32 are thus axially braced against the changeover spring 9. According to FIG. 3, the locking lugs 29, 30 are snapped onto the corresponding bearing plate 36 with their locking openings. Furthermore, according to FIGS. 4-6, the bearing bolts 27, 28 and the undercut 24 can be seen in the region of the recess 21. The changeover spring is shown in more detail in FIGS. 7 and 8. It is important that there are lower projections 37 in the foot piece 22, which engage in a rotary movement in the undercuts 24, which are circular in the area of the recess 21. As a result, the entire switching spring is secured against radial rotation and the axial displacement protection is effected by the bearing plate 32 arranged behind it with the magnet 35 and the further bearing plate 36, which cooperates with the latching lugs 29, 30.

Statt der Befestigung der Umschaltfeder in der Art einer Bajonettkupplung ist es selbstverständlich möglich, auch andere lösbare Befestigungen der Umschaltfeder mit ihrem Fußstück 22 im Bereich der öffnung 21 über Schlitze mit entsprechenden Rastnasen zu erreichen.Instead of fastening the changeover spring in the manner of a bayonet coupling, it is of course possible to also achieve other releasable fastenings of the changeover spring with its foot piece 22 in the area of the opening 21 via slots with corresponding latches.

Bei der Ausführung mit einem bistabilen Relais ergibt sich der zusätzliche Vorteil, daß die Montage der Ankerplatten und des Permanent-Magneten sehr einfach ist.The version with a bistable relay has the additional advantage that the mounting of the anchor plates and the permanent magnet is very simple.

Bei einem monostabilen Relais bedarf es keiner Wippe mit Permanentmagnet und Lagerplatte, sondern es ist ein einfacher Metallanker vorhanden, in den die Umschaltfeder in der gleichen beschriebenen Art lösbar eingesetzt ist.In the case of a monostable relay, no rocker with permanent magnet and bearing plate is required, but a simple metal armature is present, in which the changeover spring is detachably inserted in the same manner described.

Als Variante läßt sich dieses Relais auch in der Ausführung mit einem Arbeitskontakt gestalten, die dann außenliegenden Kontaktträger werden mit der Kontaktbrücke überbrückt. Der Kontaktabstand verdoppelt sich demnach gegenüber der Einmal-Umschalt-Variante.As a variant, this relay can also be designed with a make contact, the external contact carriers are then bridged with the contact bridge. The contact distance therefore doubles compared to the one-time switchover variant.
