Description

Die Erfindung bezieht sich auf ein Magnetsystem für ein Relais mit einem winkelförmigen Joch, dessen parallel zur Spulenachse angeordneter Jochschenkel beiderseits in .Längsnuten eines Grundkörpers steckbar befestigt ist.The invention relates to a magnet system for a relay with an angular yoke, the yoke leg arranged parallel to the coil axis is fastened on both sides in. Longitudinal grooves of a base body.

Bei einem bekannten Magnetsystem dieser Art (DE-GM 79 09 135) ist vorgesehen, daß der Jochschenkel mit einem Rastzahn in einer Ausnehmung des Grundkörpers einrastet. Zur kraftschlüssigen Befestigung und Positionierung des Jochschenkels im Grundkörper ist dort weiterhin vorgesehen, in den Nuten des Grundkörpers deformierbare Rippen anzuformen. Ein .derartiger Preßsitz des Joches im Grundkörper führt jedoch zu unerwünschten Spannungen im Kunststoff des Grundkörpers. Eine andere Möglichkeit der Fixierung des Joches im Grundkörper bestünde darin, das Joch in den Nuten festzukleben. Das Einbringen von Klebstoff ist jedoch in der Fertigung verhältnismäßig aufwendig; insbesondere müßte das Joch durch zusätzliche Vorkehrungen in der richtigen Position gehalten werden, bis der Klebstoff ausgehärtet ist.In a known magnet system of this type (DE-GM 79 09 135) it is provided that the yoke leg engages with a locking tooth in a recess in the base body. For the non-positive fastening and positioning of the yoke leg in the base body, it is further provided there to form deformable ribs in the grooves of the base body. Such a press fit of the yoke in the base body, however, leads to undesirable stresses in the plastic of the base body. Another possibility of fixing the yoke in the base body would be to glue the yoke in the grooves. However, the introduction of adhesive is relatively expensive in production; in particular, the yoke would have to be held in the correct position by additional precautions until the adhesive has hardened.

Aufgabe der Erfindung ist es deshalb, bei einem Magnetsystem der eingangs erwähnten Art eine sichere und leicht zu montierende Jochfixierung zu schaffen.The object of the invention is therefore to provide a secure and easy-to-assemble yoke fixation in a magnet system of the type mentioned.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß auf der der Spule zugewandten Seite des Joches ein Halteblech aus elastischem Metall angeordnet ist, welches sich mit seinem Mittelteil am Jochschenkel abstützt und mit aufgebogenen Seitenteilen beiderseits in den Längsnuten des Grundkörpers verspannt ist.According to the invention this object is achieved in that a holding plate made of elastic metal is arranged on the side of the yoke facing the coil, which is supported with its central part on the yoke leg and is braced on both sides in the longitudinal grooves of the base body with bent side parts.

Das erfindungsgemäß verwendete Halteblech kann als einfaches Stanz- und Biegeteil hergestellt und montiert werden. Aufgrund seiner Elastizität kann es die bei der kraftschlüssigen Befestigung auftretenden Kräfte aufnehmen, ohne den Kunststoffgrundkörper übermäßig zu belasten. Das Halteblech kann zusammen mit dem Joch in einem Arbeitsgang durch Einstecken im Grundkörper montiert werden. Zweckmäßigerweise wird dabei das Halteblech vor dem Einstecken mittels beidseitig angeformter, ohrenförmiger Befestigungslaschen an seitlichen Rastzähnen des Jochschenkels vormontiert. Um das Einstecken von Joch und Halteblech zu erleichtern, besitzt das Halteblech in einer vorteilhaften Ausführungsform an beiden Seitenteilen in Einsteckrichtung des Jochschenkels aufgebogene Kufen. Weiterhin ist es zweckmäßig, wenn das Halteblech zumindest an einem Seitenteil eine entgegen der Einsteckrichtung des Joches aufgebogene, in einer Ausnehmung des Grundkörpers einrastbare Ecke vorgesehen ist.The holding plate used according to the invention can be manufactured and assembled as a simple stamped and bent part. Due to its elasticity, it can absorb the forces that occur during the force-fitting fastening without putting excessive strain on the plastic base body. The holding plate can be installed together with the yoke in one step by inserting it into the base body. The holding plate is expediently preassembled on lateral latching teeth of the yoke leg before insertion by means of ear-shaped fastening tabs formed on both sides. In order to facilitate the insertion of the yoke and the holding plate, the holding plate has, in an advantageous embodiment, runners bent up on both side parts in the direction of insertion of the yoke leg. Furthermore, it is expedient if the holding plate is provided, at least on one side part, with a corner which is bent open against the direction of insertion of the yoke and can be latched into a recess in the base body.

In einer anderen vorteilhaften Ausführungsform ist das Halteblech mittels eines im Mittelbereich angeformten, den Jochschenkel in einem Durchbruch U-förmig umgreifenden Befestigungslappens befestigt. Zusätzlich kann das Halteblech in diesem Fall beiderseits angeformte, die Schmalseiten des Jochschenkels umgreifende Seitenschen-. kel aufweisen.In another advantageous embodiment, the holding plate is fastened by means of a fastening tab which is integrally formed in the central region and surrounds the yoke leg in a breakthrough in a U-shape. In this case, the holding plate can additionally be formed on both sides and encompass the narrow sides of the yoke leg. exhibit kel.

Mit besonderem Vorteil ist diese Ausführungsform der Erfindung dann anwendbar, wenn das Halteblech aus nicht ferromagnetischem Material besteht und der durch den Jochschenkel greifende Befestigungslappen gleichzeitig als Trennblech für einen auf dem Joch aufliegenden Ankerschenkel dient. Da die Dicke des Trennbleches im allgemeinen relativ gering ist und in diesem Fall das gesamte Halteblech diese geringe Dicke aufweist, kann es zweckmäßig sein, im Halteblech quer zur Längsrichtung des'Jochschenkels eingeprägte Versteifungsrippen vorzusehen.This embodiment of the invention can be used with particular advantage when the holding plate is made of non-ferromagnetic material and the fastening tab which extends through the yoke leg simultaneously serves as a separating plate for an anchor leg resting on the yoke. Since the thickness of the separating plate is generally relatively small and in this case the entire holding plate has this small thickness, it may be expedient to provide stiffening ribs embossed in the holding plate transversely to the longitudinal direction of the yoke leg.

In einer vorteilhaften Weiterbildung kann das Halteblech außerdem eine Verlängerung mit einem ausgeschnittenen Durchbruch aufweisen, welcher über einem Durchbruch des Jochschenkels liegt und zur positionsgenauen Befestigung einer Ankerhaltefeder dient. In diesem Fall kann der Durchbruch in dem dicken und verhältnismäßig schwer zu bearbeitenden Joch mit geringer Genauigkeit gearbeitet sein, da die Kanten des Durchbruchs im Halteblech maßgenau liegen.In an advantageous development, the holding plate can also have an extension with a cut-out opening, which lies above an opening in the yoke leg and is used for the positionally accurate attachment of an anchor holding spring. In this case, the opening in the thick and relatively difficult to machine yoke can be worked with low accuracy, since the edges of the opening lie in the holding plate with dimensional accuracy.

Die Erfindung wird nachfolgend an Ausführungsbeispielen anhand der Zeichnung näher erläutert. Es zeigt

  • Fig. 1 ein elektromagnetisches Relais mit einem erfindungsgemäß gestalteten Magnetsystem,
  • Fig. 2 ein Halteblech in perspektivischer Darstellung;
  • Fig. 3, 4 und 5 einen Jochschenkel mit Halteblech in verschiedenen Ansichten,
  • Fig. 6 und 7 einen Jochschenkel mit einem anders gestalteten Halteblech in zwei verschiedenen Ansichten.
  • Fig. 1 zeigt ein erfindungsgemäßes Magnetsystem 1 in einem Grundkörper 2, der außerdem einen Kontaktfedersatz 3 enthält. Das Magnetsystem besteht aus einer Spule 4, einem winkelförmigen Joch 5 mit den Schenkeln 6 und 7 sowie einem Anker 8 mit den beiden Schenkeln 9 und 10. Der parallel zur Spulenachse verlaufende Jochschenkel 7 ist beiderseits in eine Längsnut 11 des Grundkörpers 2 eingesteckt und mit seitlichen Nasen 12 und 13 in diesen Längsnuten geführt. Eine Haltefeder 14 ist jeweils mit seitlich angeformten Befestigungslaschen 15 an den Nasen 13 des Jochschenkels befestigt und mit ihren aufgebogenen Seitenteilen 16 in den Nuten 11 verspannt. Die Form und Befestigung des Haltebleches 14 soll anhand der nachfolgenden Fig. 2 bis 5 detaillierter dargelegt werden.
The invention is explained in more detail below using exemplary embodiments with reference to the drawing. It shows
  • 1 shows an electromagnetic relay with a magnet system designed according to the invention,
  • 2 shows a holding plate in a perspective view;
  • 3, 4 and 5 a yoke leg with holding plate in different views,
  • 6 and 7 a yoke leg with a differently designed holding plate in two different views.
  • 1 shows a magnet system 1 according to the invention in a base body 2, which also contains a contact spring set 3. The magnet system consists of a coil 4, an angular yoke 5 with the legs 6 and 7 and an armature 8 with the two legs 9 and 10. The yoke leg 7 running parallel to the coil axis is inserted on both sides into a longitudinal groove 11 of the base body 2 and with lateral Lugs 12 and 13 guided in these longitudinal grooves. A retaining spring 14 is in each case fastened to the lugs 13 of the yoke leg with laterally formed fastening tabs 15 and braced in the grooves 11 with their bent-up side parts 16. The shape and fastening of the holding plate 14 will be explained in more detail with reference to the following FIGS. 2 to 5.

Das Halteblech 14, das aus federndem Material, beispielsweise Federstahl, besteht, liegt mit seinem Mittelteil 14a an der Flachseite des Jochschenkels 7 an, während die vom Jochschenkel weg aufgebogenen Seitenteile 16 zur Verspannung in den Nuten 11 dienen. Mit den beiden Befestigungslaschen 15, die federnd an den Vorsprüngen 13 des Jochschenkels 7 einrasten, ist das Halteblech 14 am Jochschenkel 7 befestigt. Nach dieser Vormontage wird der Jochschenkel zusammen mit dem Halteblech in die Nuten 11 des Grundkörpers eingeschoben, wobei die angewinkelten Kufen 16a an den Seitenteilen 16 das Einschieben erleichtern. Ist der Jochschenkel 7 ganz eingeschoben, so verspreizt sich die hochgebogene Ecke 17 des einen Seitenteils in der entsprechenden Nut 11 des Grundkörpers und verhindert ein Zurückschieben des Jochschenkels 7. Im Grundkörper kann zusätzlich eine Ausnehmung 20 vorgesehen werden, in die die hochgebogene Ecke 17 einrastet.The holding plate 14, which consists of resilient material, for example spring steel, lies with its central part 14a on the flat side of the yoke leg 7, while the side parts 16 bent away from the yoke leg serve for bracing in the grooves 11. The holding plate 14 is fastened to the yoke leg 7 with the two fastening tabs 15, which snap into the projections 13 of the yoke leg 7. After this preassembly, the yoke leg is pushed together with the holding plate into the grooves 11 of the base body, the angled runners 16a on the side parts 16 making it easier to insert them. If the yoke leg 7 is pushed in completely, the bent corner 17 of one side part expands in the corresponding groove 11 of the base body and prevents the yoke leg 7 from being pushed back. A recess 20 can also be provided in the base body, into which the bent corner 17 engages.

Die Anordnung vom Jochschenkel 7 und Halteblech 14 im Grundkörper 2 ist in der Schnittdarstellung von Fig. 5 zu sehen, wo ein Teil des Grundkörpers 2 mit dargestellt ist. Durch das Halteblech 14, dessen Seitenteile 1.6 hier ungespannt gezeichnet.sind, wird der Jochschenkel 7 gegen die Schultern 18 in den Nuten 11 gedrückt.The arrangement of the yoke leg 7 and the holding plate 14 in the base body 2 can be seen in the sectional view of FIG. 5, where part of the base body 2 is also shown. The yoke leg 7 is pressed against the shoulders 18 in the grooves 11 by the holding plate 14, the side parts 1.6 of which are drawn untensioned here.

Fig. 4 zeigt zusätzlich eine geringfügige Abwandlung des Haltebleches 14, und zwar die gestrichelt gezeichnete Verlängerung 19. Diese Verlängerung überdeckt dann den Durchbruch 7a des Jochschenkels 7, der zur Befestigung und genauen Positionierung einer Ankerhaltefeder 8a (Fig. 1) dient. Die Funktion der Positionierung kann das Halteblech 14 mit seiner Verlängerung 19 übernehmen, und zwar mit genau geschnittenen Innenkonturen 19a. Die Kontur 7b des Durchbruchs 7a im Jochschenkel 7 kann dann etwas größer als die Ausnehmung im Halteblech 14, jedoch relativ ungenau, gefertigt werden. Damit vereinfacht sich die Herstellung des Joches.FIG. 4 additionally shows a slight modification of the holding plate 14, specifically the extension 19 drawn in dashed lines. This extension then covers the opening 7a of the yoke leg 7, which is used to fasten and precisely position an anchor retaining spring 8a (FIG. 1). The position of the holding plate 14 with its extension 19 can take over the function, namely with precisely cut inner contours 19a. The contour 7b of the opening 7a in the yoke leg 7 can then be made somewhat larger than the recess in the holding plate 14, but relatively imprecisely. This simplifies the manufacture of the yoke.

In den Fig. 6 und 7 ist eine weitere Ausführungsform des Haltebleches dargestellt. Dieses Halteblech 21 besitzt aufgebogene Seitenteile 22 zur Verspannung im Grundkörper; angewinkelte Kufen 22a dienen zur Erleichterung der Jochmontage. Zur Befestigung am Jochschenkel 7 ist in diesem Fall ein mittig angeordneter Befestigungslappen 23 vorgesehen, welcher U-förmig gebogen und in einem Durchbruch 24 des Jochschenkels 7 eingehängt ist. Ein Durchbruch 25 in den Befestigungslappen 23 dient dabei als Montagehilfe. Zusätzlich besitzt das Halteblech 21 rechtwinklig abgebogene Seitenschenkel 26, welche beiderseits an den Schmalseiten des Jochschenkels anliegen.6 and 7, a further embodiment of the holding plate is shown. This holding plate 21 has bent-up side parts 22 for bracing in the base body; angled runners 22a serve to facilitate the yoke assembly. For attachment to the yoke leg 7, a centrally arranged fastening tab 23 is provided in this case, which is bent in a U-shape and is suspended in an opening 24 in the yoke leg 7. An opening 25 in the mounting tab 23 serves as an assembly aid. In addition, the holding plate 21 has side legs 26 bent at right angles, which abut the narrow sides of the yoke leg on both sides.

Das freie Ende 27 des Befestigungslappens 23 liegt dem eigentlichen Halteblech 21 gegenüber auf der Flachseite des Jochschenkels 7 auf und dient gleichzeitig als Trennblech für den an dieser Stelle aufliegenden Ankerschenkel 10. Das Halteblech muß zu diesem Zweck natürlich aus'einem nicht ferromagnetischen Material, beispielsweise einer Kupferlegierung, bestehen. Der als Trennblech dienende Teil 27 kann in einer Vertiefung 28 des Jochschenkels 7 liegen, damit dieses Trennblech möglichst wenig gegenüber der Oberfläche des Jochschenkels 7 vorspringt. Das Halteblech 21 besitzt in diesem Fall insgesamt eine geringe Dicke und weist zur Versteifung eingeprägte Rippen 29 auf.The free end 27 of the fastening tab 23 lies opposite the actual holding plate 21 on the flat side of the yoke leg 7 and at the same time serves as a separating plate for the armature leg 10 resting at this point. The holding plate must, of course, be made of a non-ferromagnetic material, for example one Copper alloy. The part 27 serving as a separating plate can lie in a recess 28 of the yoke leg 7 so that this separating plate projects as little as possible from the surface of the yoke leg 7. In this case, the holding plate 21 has an overall small thickness and has ribs 29 stamped in for reinforcement.
