Abstract

An electromagnetic relay has a tongue armature disposed inside a hollow coil body and having a free end movable between two cooperating pole plates, and a fixed end having an additional spring section disposed at an angle with respect to the movable portion of the armature, the spring section being secured to one of the coil flanges, thereby extending the effective free spring length of the armature so as to improve the sensitivity of the relay. The position of the armature with respect to the pole plates is adjustable after encapsulation of the relay by irradiating the spring section of the armature with thermal pulses, such as laser pulses at specified locations.

Description

Die Erfindung bezieht sich auf ein elektromagnetisches Relais mit einem innerhalb eines Spulenkörpers angeordneten, einseitig gelagerten, federelastischen Zungenanker, welcher mit seinem freien Ende mindestens einem Gegenpolblech gegenübersteht und mit seinem anderen Ende am Spulenkörper im Bereich eines Spulenflansches befestigt ist. Außerdem bezieht sich die Erfindung auf ein Verfahren zur Justierung eines derartigen Relais.The invention relates to an electromagnetic relay with a spring-elastic tongue anchor arranged on one side within a coil body, the free end of which faces at least one opposing pole plate and is attached with its other end to the coil body in the region of a coil flange. The invention also relates to a method for adjusting such a relay.

Ein Relais der eingangs genannten Art ist beispielsweise aus der DE-AS 27 01 230 bekannt. Dort ist der federnde Zungenanker mit einem Ende an einem Träger befestigt, welcher ein Justierblech bildet, das durch ein außerhalb angelegtes Magnetfeld bleibend verstellt werden kann, um so die Stellung des Zungenankers zu justieren. Dieser Aufbau hat sich wegen der Justierbarkeit in vollständig vergossenem Zustand sehr bewährt, doch muß bei der Konstruktion der für das Justierblech benötigte Raum mit in Rechnung gestellt werden, wodurch der Spulendurchmesser nicht beliebig klein gemacht werden kann. Außerdem ist bei dem bekannten Relais die freie Federlänge des Zungenankers durch die Länge des Spulenkörperinnenraums begrenzt.A relay of the type mentioned is known for example from DE-AS 27 01 230. There, the resilient tongue anchor is attached at one end to a carrier, which forms an adjusting plate that can be permanently adjusted by an external magnetic field, so as to adjust the position of the tongue anchor. This structure has proven its worth because of the adjustability in the fully encapsulated state, but the space required for the adjusting plate must be taken into account in the construction, as a result of which the coil diameter cannot be made arbitrarily small. In addition, the free spring length of the tongue anchor is limited by the length of the coil body interior in the known relay.

Ein Relais mit einem federelastischen Zungenanker, der innerhalb des Spulenkörpers angeordnet ist, ist beispielsweise auch aus der DE-AS 19 09 940 bekannt. Dort ist der Zungenanker mit seinem Befestigungsende an eine Nase eines Anschlußstiftes angeschweißt, wobei die Justierung nur durch Biegen an dieser Nase mittels eines mechanisch angreifenden Werkzeuges möglich ist. Auch hierbei ist die freie Federlänge durch die Länge des Spulenkörperrohres begrenzt.A relay with a spring-elastic tongue anchor, which is arranged within the coil former, is also known, for example, from DE-AS 19 09 940. There, the tongue anchor is welded with its fastening end to a nose of a connecting pin, the adjustment only by bending this nose by means of a mechanical attacking tool is possible. Here too, the free spring length is limited by the length of the coil body tube.

Aufgabe der Erfindung ist es, ein Relais der eingangs genannten Art so auszugestalten, daß die freie Federlänge des Zungenankers nicht auf die Länge des Spulenkörperinnenraums beschränkt ist, so daß auch bei sehr kleiner Konstruktion und entsprechend kurzem Spulenkörper eine weiche Federkennlinie des Ankers bei gleichzeitig genügend großem Querschnitt zur Flußführung erzielbar ist. Außerdem soll der Zungenanker dieses Relais ohne Eingriff eines mechanischen Werkzeuges justierbar sein. Gleichzeitig soll durch die Erfindung ein Verfahren zur Justierung dieses Relais angegeben werden.The object of the invention is to design a relay of the type mentioned in such a way that the free spring length of the tongue anchor is not limited to the length of the coil body interior, so that even with a very small construction and a correspondingly short coil body, a soft spring characteristic of the armature with a sufficiently large one Cross-section for flow guidance is achievable. In addition, the tongue anchor of this relay should be adjustable without the intervention of a mechanical tool. At the same time, the invention is intended to provide a method for adjusting this relay.

Erfindungsgemäß wird die gestellte Aufgabe bei einem Relais der eingangs genannten Art dadurch gelöst, daß der Zungenanker im Bereich des zu seiner Befestigung dienenden Spulenflansches einen rechtwinklig zur Spulenachse abgebogenen, stirnseitig vor dem Spulenflansch liegenden zusätzlichen Federabschnitt aufweist und erst mit dem Ende dieses zusätzlichen Federabschnittes an der Stirnseite des Spulenflansches befestigt ist.According to the invention, the object is achieved in a relay of the type mentioned above in that the tongue anchor in the area of the coil flange serving for its attachment has a bent at right angles to the coil axis, lying in front of the coil flange and only with the end of this additional spring section on the End face of the coil flange is attached.

Durch den zusätzlichen Federabschnitt-, der senkrecht zur Spulenachse vor dem Spulenflansch angeordnet ist, kann der federelastische Zungenanker bei gleichem Querschnitt und bei gleicher Spulenlänge weicher gemacht werden, so daß auch geringere Kräfte eines Dauermagneten bzw. einer Erregung zum Schalten ausreichen. Das Relais wird also dadurch empfindlicher. Ein weiterer Vorteil der erfindungsgemäßen Gestaltung des Zungenankers liegt darin, daß der zusätzliche Federabschnitt auch für eine Justierung mit Wärmeimpulsen, insbesondere Laserimpulsen, zugänglich ist, wie sie beispielsweise in der DE-OS 29 18 100 beschrieben ist. Das Relais kann dadurch ohne mechanischen Angriff eines Werkzeugs justiert werden.Due to the additional spring section, which is arranged perpendicular to the coil axis in front of the coil flange, the resilient tongue anchor can be made softer with the same cross-section and with the same coil length, so that even lower forces of a permanent magnet or excitation are sufficient for switching. This makes the relay more sensitive. Another advantage of the tongue anchor design according to the invention is that the additional spring section is also accessible for adjustment with heat pulses, in particular laser pulses, as described, for example, in DE-OS 29 18 100 is written. The relay can thus be adjusted without mechanical attack by a tool.

In vorteilhafter Ausgestaltung des erfindungsgemäßen Relais liegt der abgebogene zusätzliche Federabschnitt des .Zungenankers in einer Ausnehmung des Spulenkörpers. Der Zungenanker kann dabei neben dem abgebogenen Federabschnitt einen zusätzlich angeformten Befestigungslappen aufweisen, der ebenfalls stirnseitig vor dem Spulenkörperflansch angeordnet ist, jedoch im Gegensatz zum zusätzlichen Federabschnitt auf dem Spulenflansch aufliegt. Die Befestigung der Ankerfeder kann durch verformte Befe-stigungszapfen des Spulenkörpers am Ende des zusätzlichen Federabschnitts und gegebenenfalls an dem zusätzlichen Befestigungslappen erfolgen.In an advantageous embodiment of the relay according to the invention, the bent additional spring section of the tongue anchor lies in a recess in the coil body. In addition to the bent spring section, the tongue anchor can have an additionally formed fastening tab, which is also arranged on the end face in front of the coil body flange, but, in contrast to the additional spring section, rests on the coil flange. The anchor spring can be fastened by deformed fastening pins of the coil body at the end of the additional spring section and, if appropriate, on the additional fastening tab.

Zur Justierung des Relais wird der zusätzliche Federabschnitt der Ankerfeder mit Wärmeimpulsen, insbesondere mit Laserimpulsen bestrahlt. Dabei ist es zweckmäßig, daß die Bestrahlung mit den Laserimpulsen gezielt an bestimmten Punkten einer vorgegebenen Matrix erfolgt.To adjust the relay, the additional spring section of the armature spring is irradiated with heat pulses, in particular with laser pulses. It is expedient for the laser pulses to be irradiated specifically at specific points in a given matrix.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel anhand der Zeichnung näher erläutert. Dabei zeigenThe invention is explained in more detail using an exemplary embodiment with reference to the drawing. Show

Fig: 1 bis 3 ein erfindungsgemäß gestaltetes Relais in drei verschiedenen Schnittansichten.Fig. 1 to 3 a relay designed according to the invention in three different sectional views.

Das in der Zeichnung dargestellte erfindungsgemäße Relais besitzt einen Spulenkörper 1 mit einer Wicklung 2, die durch die Spulenflansche 3 und 4 begrenzt ist. Im Spuleninnenraum 5 ist ein federelastischer Zungenanker 6 angeordnet, der mit seinem freien Ende 6a zwischen zwei Gegenpolblechen 7 und 8 bewegbar ist. Die Gegenpolbleche 7 und 8 sind abgewinkelt ausgebildet und bilden'mit ihren in einer Ebene angeordneten Abschnitten 7a und 8a eine Auflagefläche für einen flachen, vierpoligen Dauermagneten 9.The relay according to the invention shown in the drawing has a coil body 1 with a winding 2, which is limited by the coil flanges 3 and 4. A spring-elastic tongue anchor 6 is arranged in the coil interior 5, and its free end 6a can be moved between two counter-pole plates 7 and 8. The opposing pole plates 7 and 8 are angled and, with their sections 7a and 8a arranged in one plane, form one Contact surface for a flat, four-pole permanent magnet 9.

Der Zungenanker ist an dem den Gegenpolblechen entgegengesetzten Ende abgewinkelt und besitzt damit einen zusätzlichen Federabschnitt 6b, der stirnseitig vor dem Spulenflansch 3 liegt und damit die gesamte freie Federlänge des Zungenankers 6 verlängert. Das Ende 6c des zusätzlichen Federabschnittes 6b liegt auf dem Spulenflansch 3 stirnseitig auf und ist mit einem warmverformten- Zapfen 10 des Spulenkörpers befestigt. Außerdem ist seitlich vom zusätzlichen Federabschnitt 6b ein weiterer Befestigungsabschnitt 6d angeformt, der ebenfalls durch einen Zapfen 10 am Spulenflansch befestigt ist. Außerdem ist am Befe-. stigungsende 6c bzw. 6d ein Anschlußstachel 6e angeformt, der zur elektrischen Kontaktierung des gleichzeitig als Mittelkontaktfeder dienenden Zungenankers 6 dient. Um die freie Beweglichkeit des zusätzlichen Federabschnittes 6b beim Schalten des Zungenankers 6 zu gewährleisten, besitzt der Spulenflansch 3 eine Ausnehmung 3a.The tongue anchor is angled at the end opposite the counter-pole plates and thus has an additional spring section 6b, which is located in front of the coil flange 3 and thus extends the entire free spring length of the tongue anchor 6. The end 6c of the additional spring section 6b lies on the end face of the coil flange 3 and is fastened with a thermoformed pin 10 of the coil body. In addition, a further fastening section 6d is integrally formed on the side from the additional spring section 6b, which is also fastened to the coil flange by a pin 10. In addition, is on the Befe-. End 6c or 6d formed a connecting pin 6e, which serves for electrical contacting of the tongue anchor 6, which also serves as a central contact spring. In order to ensure the free mobility of the additional spring section 6b when switching the tongue anchor 6, the coil flange 3 has a recess 3a.

Zur Justierung wird der zusätzliche Federabschnitt 6b des Zungenankers 6 mit Laserimpulsen bestrahlt, die an den Punkten 11 auf diesen auftreffen und jeweils eine Deformierung des Zungenankers bewirken. Bei einer Bestrahlung in Richtung des Pfeiles 12 (Fig. 2) wird das freie Ankerende 6a in Richtung des Pfeiles 13 verstellt. Soll der Anker in Gegenrichtung verstellt werden, so könnte dies beispielsweise durch mechanischen Druck auf die Stelle 14 oder durch einen zusätzlichen mechanischen Druck an dieser Stelle 14 bei gleichzeitiger Bestrahlung mit Laserimpulsen geschehen. Für die normale Fertigung und Justierung ist es aber zweckmäßig, die Ankerzunge zunächst so zu montieren, daß das freie Ende 6a entsprechend der Darstellung in Fig. 2 am Gegenpolblech 8 anliegt, so daß der Zungenanker danach ohne mechanische Berührung allein durch Bestrahlung mit Laserimpulsen justiert werden kann. Bei der Justierung ist es außerdem zweckmäßig, ein Punkteraster, etwa wie in Fig. 3 dargestellt, auf dem zusätzlichen Federabschnitt 6b vorzusehen und je nach Größe der benötigten Verformung bestimmte Punkte dieses Rasters gezielt zu bestrahlen. Dieses Verfahren ist in der deutschen Patentanmeldung P 32 35 714.1 beschrieben.For adjustment, the additional spring section 6b of the tongue anchor 6 is irradiated with laser pulses which strike it at points 11 and each cause the tongue anchor to be deformed. When irradiated in the direction of arrow 12 (FIG. 2), the free anchor end 6a is adjusted in the direction of arrow 13. If the armature is to be adjusted in the opposite direction, this could be done, for example, by mechanical pressure at point 14 or by an additional mechanical pressure at point 14 with simultaneous irradiation with laser pulses. For normal production and adjustment, however, it is expedient to first mount the armature tongue in such a way that the free end 6a rests on the mating pole plate 8 as shown in FIG. 2, so that the tongue armature is then passed through without mechanical contact Irradiation with laser pulses can be adjusted. When adjusting, it is also expedient to provide a point grid, as shown in FIG. 3, on the additional spring section 6b and to irradiate specific points of this grid depending on the size of the required deformation. This process is described in German patent application P 32 35 714.1.

Nach der Justierung kann die Ausnehmung 3a des Spulenkörpers durch eine Folie 15 vorläufig abgedeckt werden, während die Öffnung des Spulenkörpers an der gegenüberliegenden Seite durch eine zwischen die Polblechabschnitte 7a und 8a einerseits und den Dauermagneten 9 andererseits eingelegte Folie 16 vorabgedichtet wird. Nach dem Einsetzen des Relais in eine ferromagnetische Kappe 17 können dann die Hohlräume mit Gießharz ausgegossen werden, ohne daß dieses in den Innenraum 5 eindringen kann.After the adjustment, the recess 3a of the coil former can be temporarily covered by a film 15, while the opening of the coil former on the opposite side is pre-sealed by a film 16 inserted between the pole plate sections 7a and 8a on the one hand and the permanent magnets 9 on the other. After the relay has been inserted into a ferromagnetic cap 17, the cavities can then be poured out with casting resin without it being able to penetrate into the interior 5.

Die Arbeitsweise des Relais entspricht der, wie sie bereits bei dem bekannten Relais gemäß DE-AS 27 01 230 gegeben ist. Dabei dient die ferromagnetische Kappe 17 der Flußführung des Dauermagnetkreises wie auch des Erregerkreises. Die Gegenpolbleche 7 und 8 sind in üblicher Weise mit Anschlußstiften 7b und 8b versehen. Außerdem sind in bekannter Weise Spulenanschlußstifte 18 in den Spulenkörper 1 eingebettet.The operation of the relay corresponds to that already given in the known relay according to DE-AS 27 01 230. The ferromagnetic cap 17 serves to guide the flux of the permanent magnetic circuit as well as the excitation circuit. The opposing pole plates 7 and 8 are provided in the usual way with connecting pins 7b and 8b. In addition, coil connecting pins 18 are embedded in the coil body 1 in a known manner.
