Abstract

An improved relay of conventional design is disclosed wherein the relay has an armature and at least one moveable contact element. A slide is attached to the armature and moveable contact element. The slide is of a length matched to the actual distance between the armature and the moveable contact element after the armature and moveable contact element are secured to a base and moved to a contact position.

Description

Die Erfindung betriffte ein Relais mit einem Anker, mit mindestens einem beweglichen Kontaktelement und mit einem langgestreckten Schieber zur Übertragung der Ankerbewegung auf das bewegliche Kontaktelement. Außerdem betrifft die Erfindung ein Verfahren zur Herstellung eines solchen Relais.The invention relates to a relay with an armature, with at least one movable contact element and with an elongated slide for transmitting the armature movement to the movable contact element. The invention also relates to a method for producing such a relay.

Relais mit dem erwähnten allgemeinen Aufbau, also mit einem Schieber zur Übertragung der Schaltbewegung, sind in vielen Formen bekannt. Beispielsweise zeigt die DE-A-38 35 118 ein solches Relais mit einem langgestreckten stabförmigen Schieber, der mit einer fest vorgegebenen Länge gefertigt wird. Da jedoch durch die Fertigung der Einzelteile und durch die Montage Toleranzen auftreten und sich summieren, müssen derartige Relais nach dem Zusammenbau häufig justiert werden, damit der vorgegebene Ankerhub auch zu der gewünschten Schaltbewegung an den Kontaktelementen und durch einen bestimmten Überhub zur Erzeugung einer vorgegebenen Kontaktkraft führt. Bei herkömmlichen Relais kann diese Justierung beispielsweise durch eine Biegung am Ankerende oder an den Kontaktelementen vorgenommen werden. Meist wird dabei die gewünschte Einstellung erst in mehreren Schritten mit jeweils zwischengeschalteter Messung erreicht. Außerdem sind solche Justiervorgänge nur schwer automatisierbar. Insbesondere sind diese Vorgänge nicht in einen normalen Linientakt einer Fertigungsanlage integrierbar, weil das Relais dabei mehrfach zum Messen und Nachjustieren aufgesetzt werden muß.Relays with the general structure mentioned, ie with a slide for transmitting the switching movement, are known in many forms. For example, DE-A-38 35 118 shows such a relay with an elongated rod-shaped slide, which is manufactured with a predetermined length. However, since tolerances arise and add up due to the manufacture of the individual parts and the assembly, such relays often have to be adjusted after assembly, so that the predetermined armature stroke also leads to the desired switching movement on the contact elements and through a certain overstroke to generate a predetermined contact force . With conventional relays, this adjustment can be carried out, for example, by bending the armature end or the contact elements. The desired setting is usually only achieved in several steps, each with an intermediate measurement. In addition, such adjustment processes are difficult to automate. In particular, these processes cannot be integrated into a normal line cycle of a production system because the relay has to be set up several times for measuring and readjusting.

Aus der DE-PS 10 61 441 ist weiterhin ein Relais bekannt, bei dem der Schieber zwar eine feste Länge hat, dessen Befestigungsstelle am Anker aber durch eine verstellbare Schraube gebildet wird. Eine solche Justierung erfordert jedoch nicht nur eine aufwendige Handarbeit, sondern auch eine in der Massenfertigung nicht mehr vertretbare Konstruktion.From DE-PS 10 61 441 a relay is also known, in which the slide has a fixed length, but the fastening point on the armature is formed by an adjustable screw. However, such an adjustment not only requires complex manual work, but also a construction that is no longer justifiable in mass production.

Ziel der vorliegenden Erfindung ist es, ein Relais der eingangs genannten Art so zu gestalten, daß die Justierung zum Ausgleich der Fertigungstoleranzen mit einfachen Mitteln in den normalen Fertigungsablauf, nämlich den Linientakt einer Massenproduktion, einbezogen werden kann, wobei insbesondere kein mehrfaches Messen und Nachjustieren erforderlich ist.The aim of the present invention is to design a relay of the type mentioned at the outset so that the adjustment to compensate for the manufacturing tolerances can be incorporated into the normal manufacturing process, namely the line cycle of mass production, using simple means, in particular requiring no multiple measurements and readjustments is.

Erfindungsgemäß wird dieses Ziel dadurch erreicht, daß die Länge des Schiebers individuell dem durch die Fertigungstoleranzen bedingten tatsächlichen Abstand zwischen dem Anker und dem beweglichen Kontaktelement bei einem vorgegebenen Schaltzustand angepaßt ist.According to the invention, this aim is achieved in that the length of the slide is individually adapted to the actual distance between the armature and the movable contact element, which is caused by the manufacturing tolerances, for a given switching state.

Bei dem erfindungsgemäßen Relais werden also nicht Anker oder Kontaktfedern nach der vollständigen Montage durch Biegen oder auf sonstige Weise an die fest vorgegebene Länge des Schiebers angepaßt, sondern es wird die wirksame Länge des Schiebers an die Herstellungs- und Montagetoleranzen der Funktionsteile des Relais angepaßt.In the relay according to the invention, anchors or contact springs are not adapted after the complete assembly by bending or in any other way to the fixed length of the slide, but the effective length of the slide is adapted to the manufacturing and assembly tolerances of the functional parts of the relay.

Das erfindungsgemäße Verfahren zur Herstellung eines solchen Relauf umfaßt demnach die folgenden Schritte:

  • a) Die Funktionselemente des Relais, insbesondere der Anker und das bewegliche Kontaktelement bzw. die beweglichen Kontaktelemente, werden ohne Schieber in ihrer endgültigen Lage zusammengebaut,
  • b) der Anker und jedes bewegliche Kontaktelement werden unabhängig voneinander in eine einem vorgegebenen Betriebszustand entsprechende Stelle gebracht,
  • c) dann wird der Abstand zwischen dem Anker und jedem beweglichen Kontaktelement gemessen und
  • d) schließlich wird der Schieber mit einer dem gemessenen Abstand entsprechenden wirksamen Länge hergestellt und dann montiert.
The method according to the invention for producing such a relay accordingly comprises the following steps:
  • a) The functional elements of the relay, in particular the armature and the movable contact element or the movable contact elements, are assembled in their final position without a slide,
  • b) the armature and each movable contact element are brought independently of one another into a position corresponding to a predetermined operating state,
  • c) then the distance between the armature and each movable contact element is measured and
  • d) finally the slide is manufactured with an effective length corresponding to the measured distance and then assembled.

Am einfachsten ist die maßgenaue Herstellung des Schiebers durch Abschneiden von einer vorgefertigten Maximallänge oder von einem Band zu bewerkstelligen. Denkbar wäre aber auch eine Verformung des Schiebers, etwa das Eindrücken, Vergrößern oder Verkleinern einer Sicke bei einem Schieber aus Blech. Auch eine Verformung eines Kunststoffschiebers, beispielsweise durch Ultraschall, wäre denkbar.The easiest way to do this is to produce the slider precisely to size by cutting it from a prefabricated maximum length or from a tape. It would also be conceivable to deform the slider, for example by pressing, enlarging or reducing a bead in the case of a slider made of sheet metal. A deformation of a plastic slide, for example by ultrasound, would also be conceivable.

The invention is explained in more detail below using exemplary embodiments with reference to the drawing. It shows

Das in Figur 1 schematisch dargestellte Relais zeigt einen Sockel 1, auf welchem ein Magnetsystem mit einer Spule 2, einem Kern 3 und einem Joch 4 angeordnet ist. In dem Sockel 1 sind außerdem feststehende Gegenkontaktelemente 5 und 6 sowie ein Anschlußelement 7 für eine Mittelkontaktfeder 8 verankert; letztere bildet mit den beiden Gegenkontaktelementen 5 und 6 einen Umschaltkontakt oder Wechsler. Ein an dem Joch 4 gelagerter Anker 9 bildet mit dem Ende des Kerns 3 einen Arbeitsluftspalt 10 und betätigt mit seinem freien Ende 11 über einen langgestreckten, kartenförmigen oder stabförmigen Schieber 12 die Mittelkontaktfeder 8. Bei Erregung des Magnetsystems nimmt der Anker die gestrichelt gezeigte Position 9' ein; entsprechend wird die Mittelkontaktfeder 8 in die gestrichelte Position 8' umgeschaltet, also vom Öffner-Kontaktelement 6 zum Schließer-Kontaktelement 5. Soweit handelt es sich um einen allgemein bekannten Aufbau eines Relais.The relay shown schematically in FIG. 1 shows a base 1 on which a magnet system with a coil 2, a core 3 and a yoke 4 is arranged. Fixed counter contact elements 5 and 6 and a connecting element 7 for a center contact spring 8 are also anchored in the base 1; the latter forms with the two Mating contact elements 5 and 6 a changeover contact or changeover contact. An armature 9 mounted on the yoke 4 forms a working air gap 10 with the end of the core 3 and, with its free end 11, actuates the central contact spring 8 via an elongated, card-shaped or rod-shaped slide 12. When the magnet system is excited, the armature takes the position 9 shown in broken lines 'a; Accordingly, the center contact spring 8 is switched to the dashed position 8 ', that is, from the normally closed contact element 6 to the normally open contact element 5. As far as this is a generally known structure of a relay.

Um die Fertigungstoleranzen der einzelnen Teile und ihrer Befestigungslage auszugleichen, ist es beispielsweise möglich, das im Querschnitt verminderte Ende 11 des Ankers zu biegen und damit zu justieren; üblich ist es auch, die feststehenden Gegenkontaktelemente 5 und 6 und/oder auch die Mittelkontaktfeder 8 durch Biegen zu justieren.In order to compensate for the manufacturing tolerances of the individual parts and their fastening position, it is possible, for example, to bend the end 11 of the armature, which has a reduced cross section, and thus to adjust it; It is also common to adjust the fixed counter-contact elements 5 and 6 and / or the center contact spring 8 by bending.

Bei dem erfindungsgemäßen Relais wird nun anstelle der herkömmlichen Justierung die wirksame Länge des Ankers (ohne Berücksichtigung der Haltenasen an den Enden) individuell gewählt. Zu diesem Zweck wird das Relais gemaß Figur 1 zusammengebaut, jedoch ohne den Schieber 12. Danach wird beispielsweise gemäß Figur 2 das System erregt, so daß der Anker 9 an der Polfläche des Kerns 3 anliegt. Gleichzeitig wird mit einem andeutungsweise gezeichneten Hilfsstift 13 die Mittelkontaktfeder 8 in die Schließstellung bewegt, bis sie das Schließer-Kontaktelement 5 berührt. Dann wird der Abstand D zwischen dem Anker und der Mittelkontaktfeder 8 an den jeweiligen Angriffspunkten des Schiebers gemessen. Um die wirksame Schieberlange zu ermitteln, muß dann noch ein Betrag d für den Überhub addiert werden. Um diesen Betrag muß die Mittelkontaktfeder 8 nach dem Schließen des Kontakts weiterbewegt werden, um den gewünschten Kontaktdruck zu erzeugen. Mit diesem Schiebermaß D + d wird dann für jedes montierte Relais ein Schieber zurechtgeschnitten. Beispielsweise wird gemäß Figur 3 von einem Band das Maß D + d mit einem Schneidgerät 14 entlang der Schnittlinie 15 abgeschnitten. Die Nasen 16 an den Schieberenden haben keinen Einfluß auf die wirksame Länge des Schiebers und bleiben deshalb außer Betracht.In the relay according to the invention, the effective length of the armature (without taking into account the retaining lugs at the ends) is now individually selected instead of the conventional adjustment. For this purpose, the relay is assembled in accordance with FIG. 1, but without the slide 12. Thereafter, for example in accordance with FIG. 2, the system is excited so that the armature 9 rests on the pole face of the core 3. At the same time, the center contact spring 8 is moved into the closed position with an auxiliary pin 13, which is indicated in the drawing, until it touches the make contact element 5. Then the distance D between the armature and the center contact spring 8 is measured at the respective points of application of the slide. To determine the effective slide length, an amount d must then be added for the overstroke. By this amount, the center contact spring 8 has to be moved further after the contact has been closed in order to produce the desired contact pressure. With this slide dimension D + d, a slide is then cut to size for each installed relay. For example, according to FIG. 3, the dimension D + d is cut off from a strip with a cutting device 14 along the cutting line 15. The lugs 16 on the slide ends have no influence on the effective length of the slide and are therefore not taken into account.

In den Figuren 4, 5 und 7 sind in der Draufsicht auf ein Relais gemaß Figur 1 verschiedene Kontakt- und Schieberanordnungen gezeigt. In Figur 4 ist der in Figur 1 dargestellte Fall mit nur einem Schieber 12 gezeigt. In diesem Fall werden, wie bereits anhand der Figur 3 erläutert, die Endkanten 15 beschnitten, um die wirksame Schieberlänge zu erhalten. Natürlich könnten auch am gegenüberliegenden Ende des Schiebers dessen Endkanten 17 zur Längeneinstellung beschnitten werden.In Figures 4, 5 and 7, a top view of a relay according to Figure 1 shows various contact and slide arrangements. FIG. 4 shows the case shown in FIG. 1 with only one slide 12. In this case, as already explained with reference to FIG. 3, the end edges 15 are trimmed in order to maintain the effective slide length. Of course, the end edges 17 of the slider could also be cut for length adjustment at the opposite end.

In Figur 5 ist schematisch eine Ausführungsform mit zwei nebeneinanderliegenden Umschaltkontakten gezeigt. In diesem Fall werden beispielsweise zwei in einer Ebene nebeneinanderliegende Mittelkontaktfedern 18 über zwei ebenfalls in einer gemeinsamen Ebene liegende Schieber 22 betätigt. Der Anker 19 besitzt in diesem Fall zwei gabelförmig nebeneinanderliegende Ende 20 und 21 zur Betätigung der beiden Einzelschieber 22. Für jeden dieser Schieber 22 wird jedoch unabhängig die erforderliche wirksame Lange ermittelt und durch Abtrennen an der Schnittlinie 25 hergestellt. Auf diese Weise kann auch ein fertigungsbedingter Versatz der beiden Ankerenden 20 und 21 ausgeglichen werden.FIG. 5 schematically shows an embodiment with two changeover contacts lying next to one another. In this case, for example, two center contact springs 18 lying side by side in one plane are actuated via two slides 22 also lying in a common plane. In this case, the armature 19 has two fork-like ends 20 and 21 for actuating the two individual slides 22. However, the required effective length is determined independently for each of these slides 22 and is produced by cutting off at the cutting line 25. In this way, a manufacturing-related offset of the two anchor ends 20 and 21 can also be compensated for.

Ein Mehrwechslerrelais kann jedoch auch mit einem einzigen Schieber betrieben werden, wie dies beispielsweise in Figur 7 für vier Umschaltkontakte gezeigt ist. In diesem Fall wird über einen Anker 29 ein Schieber 32 betätigt, welcher seinerseits über Fensterausschnitte 33 und 34 und mit seinem freien Ende 35 insgesamt vier Mittelkontaktfedern 38 betätigt. Bei der Herstellung des Relais wird nun nach dem erfindungsgemäßen Prinzip für jede der Mittelkontaktfedern 38 die erforderliche Schieberlange ermittelt, und bei der Herstellung des Schiebers werden diese unterschiedlichen Längen durch Beschneiden an den vier Betätigungskanten 39, 40, 41 und 42 berücksichtigt.However, a multi-changeover relay can also be operated with a single slide, as is shown, for example, in FIG. 7 for four changeover contacts. In this case, a slide 32 is actuated via an armature 29, which in turn actuates a total of four central contact springs 38 via window cutouts 33 and 34 and with its free end 35. In the manufacture of the relay, the required slide length is now determined for each of the center contact springs 38 according to the principle of the invention, and in the manufacture of the slide these different lengths are taken into account by trimming the four actuating edges 39, 40, 41 and 42.

So kann insbesondere bei Mehrwechslerrelais durch unterschiedliches Beschneiden des Schiebers auch der Gleichlauf der Kontaktfedern sichergestellt werden.In this way, the synchronism of the contact springs can be ensured, in particular in the case of multi-changeover relays, by trimming the slide differently.
