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 bekannt aus der DE-OS 30 08 783. Dort besteht der SpuLenkörper mit dem U-Bügel mit BLattfederteil aus einem einzigen Formteil aus Kunststoff. Diese Art hat sich zwar in der Praxis gut bewährt, jedoch ist es für hohe Genauigkeiten bei der HersteLLung notwendig, die Spritzbedingungen, insbesondere die Temperatur, und die MischungsverhäLtnisse bei mit Faserstoffen versetzten Kunststoffen genau einzuhalten.Such a relay is known from DE-OS 30 08 783. There, the bobbin with the U-bracket with leaf spring part consists of a single molded part made of plastic. Although this type has proven itself well in practice, it is necessary for high accuracy in production to adhere precisely to the spraying conditions, in particular the temperature, and the mixing ratios of plastics containing fibers.

Mit der vorliegenden Erfindung soll daher die Aufgabe gelöst werden, trotz geringerer Präzisionserfordernisse bei der HersteLLung des SpuLenkörpers eine rationeLLe und qualitativ hochwertige Fertigung des BLattfederteils bei gleich guter oder besserer Funktion derselben zu erreichen.With the present invention, therefore, the object is to be achieved, despite lower precision requirements in the manufacture of the bobbin, to achieve a rational and high-quality manufacture of the leaf spring part with the same or better function thereof.

Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen MerkmaLe gelöst. Der Quersteg mit BLattfederteil ist ein billiges Stanzteil aus geeignetem, federnden MateriaL, wie z.B. Federbronce, und kann Leicht durch W.Minks 30
elastische AusLenkung der Schenkel und/oder des Quersteges in die Schlitze der SchenkeL eingerastet werden.This object is achieved by the features specified in the characterizing part of claim 1. The crossbar with leaf spring part is a cheap stamped part made of suitable, resilient material, such as spring bronze, and can easily pass through W.Minks 30
elastic deflection of the legs and / or the crossbar can be snapped into the slots of the leg.

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.This also makes it possible to replace the cross bar with leaf spring part by another, the spring action of which acts on the KL anchor in a different strength and / or at a different angle. As a result, the coil body can also be used for other types of clap anchors, e.g. for different relay types.

Weitere vorteilhafte EinzeLheiten der Erfindung sind den Unteransprüchen und der nachföLgenden Beschreibung eines Ausführunasbeispiels der Erfindung zu entnehmen.Further advantageous details of the invention can be found in the subclaims and the following description of an exemplary embodiment of the invention.

  • Fig. 1 zeigt einen SpuLenkörper mit dem erfindungsgemäßen Quersteg in perspektivischer Ansicht undFig. 1 shows a bobbin with the crossbar according to the invention in a perspective view
  • Fig. 2 denselben bewickeLt und mit einem Magnetsystem versehen von der Seite im Schnitt.Fig. 2 wound the same and provided with a magnet system from the side in section.

An dem aus einem Kunststoff-FormteiL 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 wenigstens je einem SchLitz 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 SchLitze 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 extending on a flange 2 in the direction of the coil axis 3 are molded onto the coil body 1, which is injection molded from a plastic molded part made of elastic plastic. At the end 6, these are each provided with at least one slot 7, into which a plug-in tab 8 provided at the ends of a transverse web 9 made of elastically resilient material can be latched. The locking takes place by elastic deflection of the legs 4, 5 and / or the crossbar 9. The slots 7 and the plug-in tabs 8 are designed so that a play-free fixation of the crossbar 9 is obtained. SchenkeL 4 5 and crossbar 9 thus form a U-bracket.

W.Minks 30W.Minks 30

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 aufgewickelt.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 magnetic coil 15 is wound on the coil core.

ALs Material für den Quersteg 9 mit Blattfederteil 10 dient ein federndes Metall, wie beispielsweise Federbronce.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, in particular at higher temperatures, the plastic with fiber materials, such as Glass fibers, reinforced.
