Abstract

An electromagnetic relay with an angular armature and a U-shaped yoke disposed on the coil form flange. The yoke comprises two legs extending in the direction of the coil axis, and a crosspiece having a foil-spring portion which rests on the angular edge of the tilting armature. The crosspiece carrying the foil-spring portion is clamped into position between the two legs. The crosspiece is made from a resilient material and is provided at its ends with flap members which engage into corresponding slots formed at the ends of the legs.

Description

Die vorliegende Erfindung bezieht sich auf ein elektromagnetisches Relais gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to an electromagnetic relay according to the preamble of claim 1.

Ein derartiges Relais ist aus der DE-U-7 529 555 bekannt. Dort sind die die Andruckfeder haltenden Schenkel aus dem Jochmaterial freigeschnitten und daher nicht federnd auslenkbar, sondern höchstens verbiegbar. Aus diesem Grund muss die Andruckfeder beim Einsetzen stark federnd elastisch verformt werden. Dies kann die Federcharakteristik unter Umständen so stark beeinflussen, dass sie nicht mehr innerhalb einer zu fordernden Toleranz liegt. Offensichtlich ist auch aus diesem Grund die bekannte Andruckfeder mehrfach winklig abgebogen, so dass eine bessere Biegbarkeit des Quersteges gegeben ist. Aber auch derartige winklige Biegungen beeinflussen unter Umständen die Federcharakteristik in ungünstiger Weise.Such a relay is known from DE-U-7 529 555. There, the legs holding the pressure spring are cut out of the yoke material and are therefore not deflectable in a resilient manner, but at most can be bent. For this reason, the pressure spring must be elastically deformed when it is inserted. Under certain circumstances, this can influence the spring characteristic to such an extent that it no longer lies within a tolerance to be demanded. For this reason, too, the known pressure spring is obviously bent at multiple angles, so that the crossbar is more flexible. But even such angled bends can have an unfavorable effect on the spring characteristics.

Weiterhin ist es aus der DE-A-3 008 783 bekannt, bei einem Relais der genannten Art die Andruckfeder mit einem U-Bügel zusammen mit dem Spulenkörper aus einem einzigen Formteil aus Kunststoff herzustellen. Diese Art hat sich zwar in der Praxis gut bewährt, jedoch ist es für hohe Genauigkeiten bei der Herstellung nowendig, die Spritzbedingungen, insbesondere die Temperatur und die Mischungsverhältnisse, bei mit Faser versetzten Kunststoffen genau einzuhalten.Furthermore, it is known from DE-A-3 008 783 to produce the pressure spring with a U-bracket together with the coil body from a single molded part made of plastic in a relay of the type mentioned. Although this type has proven itself in practice, it is necessary for high accuracy in production to strictly adhere to the spraying conditions, in particular the temperature and the mixing ratios, when plastics are mixed with fibers.

Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, bei einem Relais mit einer Andruckfeder der eingangs genannten Art eine Konstruktion anzugeben, mit der es möglich ist, die Andruckfeder ohne oder höchstens mit geringer elastischer Verformung in die Schenkel einrasten zu können.The present invention is intended to achieve the object of specifying a construction for a relay with a pressure spring of the type mentioned at the outset, with which it is possible to snap the pressure spring into the legs without or at most with little elastic deformation.

Gelöst wird diese Aufgabe durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale. Durch diese Ausgestaltung kann die Andruckfeder durch seitliche Auslenkung der Schenkel leicht ohne Veränderung von deren Federcharakteristik eingerastet werden. Weiterhin können durch die besondere Anordnung der Durchbrüche in den Schenkeln und der zugeordneten Stecklaschen an den Querstegenden die Schenkel in Gegensatz zu der bekannten Ausführung dünnwandig ausgebildet werden, was die Elastizität und Herstellung günstig beeinflusst.This object is achieved by the features specified in the characterizing part of claim 1. With this configuration, the pressure spring can easily be snapped in by lateral deflection of the legs without changing their spring characteristics. Furthermore, in contrast to the known design, the legs can be thin-walled due to the special arrangement of the openings in the legs and the associated plug-in tabs on the crossbar ends, which has a favorable influence on the elasticity and production.

Hierdurch ist es weiterhin möglich, den Quersteg mit Blattfederteil durch einen anderen zu ersetzen, dessen Federwirkung in anderer Stärke und/oder einem anderen Winkel auf den Klappanker einwirkt. Hierdurch kann der Spulenkörper auch für andersartig aufgebaute Klappanker, also z. B. für verschiedene Relaistypen, verwendet werden.As a result, it is also possible to replace the crossbar with leaf spring part by another, the spring action of which acts on the folding anchor in a different strength and / or at a different angle. As a result, the coil former can also be used for differently constructed hinged anchors, that is, for. B. for different types of relays.

Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen und der nachfolgenden Beschreibung eines Ausführungsbeispiels der Erfindung zu entnehmen.

  • Fig. 1 zeigt einen Spulenkörper mit Ankerandruckfeder in perspektivischer Ansicht und
  • Fig. 2 denselben bewickelt und mit einem Magnetsystem versehen von der Seite im Schnitt.
Advantageous embodiments of the invention can be found in the subclaims and the following description of an embodiment of the invention.
  • Fig. 1 shows a coil body with anchor pressure spring in a perspective view and
  • Fig. 2 wound the same and provided with a magnet system from the side in section.

An dem aus elastischem Kunststoff gespritzten Spulenkörper 1 sind an einem Flansch 2 in Richtung der Spulenachse 3 verlaufende Schenkel 4, 5 angeformt. Diese sind am Ende 6 mit je einem Durchbruch 7 versehen, in die eine an den Enden eines aus elastisch federndem Material bestehenden Quersteges 9 vorgesehene Stecklaschen 8 einrastbar sind. Das Einrasten erfolgt durch elastische Auslenkung der Schenkel 4, 5 und/oder des Quersteges 9. Die Durchbrüche 7 und die Stecklaschen 8 sind so ausgeführt, dass eine spielfreie Fixierung des Quersteges 9 erhalten wird. Schenkel 4, 5 und Quersteg 9 bilden damit einen U-Bügel.Legs 4, 5, which extend in the direction of the coil axis 3, are formed on a flange 2 on the coil body 1, which is injection molded from elastic plastic. These are each provided at the end 6 with an opening 7, into which a plug-in tab 8 provided at the ends of a transverse web 9 made of resilient material can be latched. The engagement takes place by means of elastic deflection of the legs 4, 5 and / or of the cross bar 9. The openings 7 and the plug-in tabs 8 are designed such that the cross bar 9 is fixed without play. Legs 4, 5 and crossbar 9 thus form a U-bracket.

Am Quersteg 9 ist ein Blattfederteil 10 angeformt, das federnd gegen die Winkelkante eines Winkel-Klappankers 12 des noch aus Kern 13 und Joch 14 bestehenden Magnetkreises drückt. Auf dem Spulenkern ist die Magnetspule 15 aufgewikkelt.A leaf spring part 10 is integrally formed on the crosspiece 9, which resiliently presses against the angular edge of an angle hinged armature 12 of the magnetic circuit still consisting of core 13 and yoke 14. The magnet coil 15 is wound onto the coil core.

Als Material für den Quersteg 9 mit Blattfederteil 10 dient ein federndes Metall, wie beispielsweise Federbronze.A springy metal, such as spring bronze, serves as the material for the crossbar 9 with leaf spring part 10.

Zur Erhöhung der Festigkeit des Spulenkörpers 1, insbesondere bei höheren Temperaturen, ist der Kunststoff mit Faserstoffen, wie z. B. Glasfasern, verstärkt.To increase the strength of the bobbin 1, especially at higher temperatures, the plastic with fibrous materials, such as. B. glass fibers, reinforced.
