Abstract

Der Spulenkörper besitzt Hilfsstützpunkte für die Wicklungsenden in Form jeweils zweier Haltezapfen (7), welche zwischen sich einen Durchbruch (6) im Spulenkörper einschließen. In diesen Durchbruch kann nach dem Wickeln der Spule ein metallisches Anschlußelement (10) eingesteckt werden, so daß sein freies Ende (10a) zwischen den Haltezapfen (7) liegt und mit den bereits auf die Haltezapfen aufgebrachten Wicklungsende (9) verlötet werden kann.The coil former has auxiliary support points for the winding ends in the form of two retaining pins (7), which enclose an opening (6) between them in the coil former. A metallic connection element (10) can be inserted into this opening after winding the coil, so that its free end (10a) lies between the holding pins (7) and can be soldered to the winding end (9) already attached to the holding pins.

Description

Die Erfindung bezieht sich auf einen Spulenkörper aus Isolierstoff mit in einem Flanschteil vorgesehenen Durchbrüchen zur steckbaren Befestigung von metallischen Anschlußelementen für Wicklungsenden.The invention relates to a coil former made of insulating material with openings provided in a flange part for the pluggable fastening of metallic connection elements for winding ends.

Spulen für Relais oder andere Schaltgeräte werden gewöhnlich mit Automaten gewickelt und dann als ganzes in das entsprechende Gerät eingesetzt. Soweit im Spulenkörper bereits Anschlußstifte vor dem Wickeln durch Einspritzen oder durch Einstecken befestigt sind, können die Wicklungsenden unmittelbar vom Wicklungsautomaten an die Anschlußstifte angewickelt und in einem nachfolgenden Arbeitsgang mit diesen verlötet uerden.Coils for relays or other switching devices are usually wound with automatic machines and then inserted as a whole into the corresponding device. Insofar as connection pins are already fixed in the coil former by injecting or plugging in before winding, the winding ends can be wound directly from the winding machine onto the connection pins and soldered to them in a subsequent operation.

Vielfach ist es jedoch aus fertigungstechnischen Gründen nicht möglich, die Spulenanschlußelemente bereits vor dem Wickeln am Spulenkörper anzubringen, beispielsweise, wenn es sich um größere Blech-Anschlußelemente handelt. In diesem Fall ist für das mechanisierte Anwickeln der Spu- lenenden jeweils ein Hilfsstützpunkt erforderlich, der entweder am Isolierstoff des Spulenkörpers angeformt oder in Form eines Drahtes in diesem verankert sein kann. In diesen Fällen ist es meist arbeitsaufwendig, die Wicklungsenden bzw. die sie tragenden Anschlußdrähte nachträglich mit eingesteckten Blechanschlußteilen zu verbinden.In many cases, however, it is not possible for production-related reasons to attach the coil connection elements to the coil former before winding, for example if larger sheet metal connection elements are involved. In this case, the S p u for the mechanized initial winding - in each case an auxiliary base lenenden required, which can be either integrally formed or on the insulating material of the coil body anchored in the form of a wire therein. In these cases, it is usually labor intensive to subsequently connect the winding ends or the connecting wires carrying them to inserted sheet metal connecting parts.

Aufgabe der Erfindung ist es, einen Spulenkörper so auszubilden, daß die Wicklungsenden in einfacher Weise mechanisiert an Hilfsstützpunkte angewickelt und danach durch einfaches Löten mit nachträglich eingesteckten metallischen Anschlußelementen verbunden werden können.The object of the invention is to provide a bobbin so that the winding ends me in a simple manner chanized wound on auxiliary bases and can then be connected by simply soldering to subsequently inserted metal connection elements.

Erfindungsgemäß wird diese Aufgabe an einem Spulenkörper der eingangs genannten Art dadurch gelöst, daß zumindest an zwei gegenüberliegenden Randbereichen der Druchbrüche Haltezapfen am Spulenkörper angeformt sind, welche jeueils mindestens so breit sind wie der zwischen ihnen durch den Durchbruch steckbare Teil eines Anschlußelementes.According to the invention, this object is achieved on a bobbin of the type mentioned at the outset in that retaining pins are formed on at least two opposite edge regions of the openings, which are each at least as wide as the part of a connecting element which can be inserted between them through the opening.

Bei dem erfindungsgemäßen Spulenkörper bilden also jeueils zwei einen Durchbruch für ein Anschlußelement zuischen sich einschließende Haltezapfen gemeinsam einen Wickelstützpunkt, auf welchem ein Wicklungsende so aufgewickelt werden kann, daß ein Anschlußelement nachträglich noch zwischen die Haltezapfen bzu. in die Schlaufe des Wicklungsendes eingesteckt und mit dem Wicklungsande verlötet werden kann. Dabei ist es zueckmäßig, daß die Haltezapfen entweder zu ihrem freien Ende hin einen Absatz aufweisen oder gemeinsam auf einer abgesetzten Fläche des Spulenkörpers stehen. In diesem Fall wird sichergestellt, daß das Wicklungsende gut für das Lötwerkzeug zugänglich ist. Das Anschlußelement wird zueckmäßigerueise mit seinem freien Ende zwischen den beiden Haltezapfen verdrallt. In diesem Fall sollten die Haltezapfen in ihrer Breite dem verdrallten und damit querstehenden Ende das Anschlußelementes entsprechen. Das Anschlußelement kann jedoch auch durch einen abgebogenen Lappen am Spulenkörper fixiert uerden.In the bobbin according to the invention, two holding pins forming a breakthrough for a connecting element, together forming a winding base, on which one end of the winding can be wound such that a connecting element is added between the holding pins. can be inserted into the loop of the winding end and soldered to the winding sands. It is uncomfortable that the holding pins either have a shoulder towards their free end or stand together on a stepped surface of the coil body. In this case it is ensured that the winding end is easily accessible for the soldering tool. The connecting element is twisted with its free end between the two holding pins. In this case, the width of the retaining pins should correspond to the twisted and thus transverse end of the connecting element. However, the connecting element can also be fixed to the coil body by a bent tab.

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

  • Fig. 1 und 2 einen erfindungsgemäßen Spulenkörper in zwei Ansichten,
  • Fig. 3 bis 5 in Detaildarstellung jeweils verschiedene Ausführungsformen von Haltezapfen mit zuischenliegendem Anschlußelement und angewickeltem Wicklungsende.
The invention is explained in more detail below using exemplary embodiments with reference to the drawing. Show it
  • 1 and 2 a bobbin according to the invention in two views,
  • Fig. 3 to 5 in detail each different embodiments of retaining pins with interposed connecting element and wound winding end.

Der in den Fig. 1 und 2 dargestellte Spulenkörper 1 besitzt ein Spulenrohr 2 zur Aufnahme einer Wicklung sowie zwei Flansche 3 und 4. Am Spulenflansch 4 ist ein Ansatz 5 angeformt, welcher Durchbrüche 6 zur Aufnahme von hier nicht dargestellten Blech-Anschlußelementen besitzt. Zu beiden Seiten eines jeden Durchbruchs 6 sind Haltezapfen 7 angeformt, welche jeweils breiter sind als der Durchbruch 6, so daß ein über beide Haltezapfen 7 gewickeltes Wicklungsende das Einstecken eines Anschlußelementes nicht behindert. Die Haltezapfen besitzen jeweils einen Absatz 8, so daß das auf das freie Ende 7a gewickelte Wicklungsende nicht nach unten rutschen kann und somit zum Löten gut zugänglich bleibt.The coil body 1 shown in FIGS. 1 and 2 has a coil tube 2 for receiving a winding and two flanges 3 and 4. An extension 5 is formed on the coil flange 4, which has openings 6 for receiving sheet metal connecting elements, not shown here. Holding pins 7 are formed on both sides of each opening 6, each of which is wider than the opening 6, so that a winding end wound over both holding pins 7 does not hinder the insertion of a connecting element. The holding pins each have a shoulder 8, so that the winding end wound on the free end 7a cannot slide down and thus remains easily accessible for soldering.

In Fig. 3 ist in perspektivischer Darstellung ein Detailausschnitt aus dem in Fig. 1 und 2 dargestellten Spulenkörper gezeigt. Die auf dem Ansatz 5 des Spulenkörpers angeordneten Haltezapfen 7 tragen dabei bereits ein angeuickeltes Wicklungsende 9, das mit mehreren Windungen um die'abgesetzten Enden 7a der Haltezapfen 7 geschlungen ist.3 shows a perspective view of a detail from the coil former shown in FIGS. 1 and 2. The holding pins 7 arranged on the extension 5 of the coil former already carry a wound winding end 9 which is wound with several turns around the offset ends 7a of the holding pins 7.

Nach dem Wickeln der Spule wird in den Durchbruch 6 ein Anschlußelement 10 eingesteckt, so daß sein freies Ende 10a zwischen den Haltezapfen 7 liegt. Zur Fixierung des Anschlußelementes wird dieses freie Ende 10a verdrallt. Danach kann auf einfache Weise durch Löten die elektrische Verbindung zwischen dem Wicklungsende 9 und dem Anschlußelement 10 hergestellt uerden.After winding the coil, a connection element 10 is inserted into the opening 6, so that its free end 10a lies between the holding pins 7. This free end 10a is twisted to fix the connection element. Thereafter, the electrical connection between the winding end 9 and the connecting element 10 can be established in a simple manner by soldering.

Eine etwas abgewandelte Ausführungsform gegenüber Fig. 3 zeigt Fig. 4. Hierbei sind zwei Haltezapfen 17 auf einer erhöhten Fläche 18 des Spulenkörperansatzes 5 angeordnet, so daß auch in diesem Fall ein Abrutschen des Wicklungsendes 9 verhindert uird. Das Anschlußelement 10 ist in gleicher Weise wie vorher eingesteckt und verdrallt.A somewhat modified embodiment compared to FIG. 3 is shown in FIG. 4. Here there are two retaining pins 17 on one Elevated surface 18 of the bobbin approach 5 arranged so that slipping of the winding end 9 is prevented in this case too. The connecting element 10 is inserted and twisted in the same way as before.

Eine weitere Abwandlung zeigt Fig. 5. Dabei sind zwei Haltezapfen 27 jeweils so geformt, daß sie das zwischen ihnen eingesteckte Anschlußelement 30 jeweils U-förmig umgeben. Dieses Anschlußelement 30 wird dann in dem beiderseitig vorgesehenen Schlitz 31 mit dem Wicklungsende 9 verlötet. Ein Absatz 28 verhindert auch hier das Abrutschen des Wicklungsendes nach unten. Zur Fixierung des Halteelementes 30 ist dieses bei diesem Ausführungsbeispiel mit einem seitlichen Lappen 32 versehen, welcher in einem seitlichen Schlitz 33 eines Haltezapfens 27 liegt und durch seitliches Biegen das Anschlußelement 30 am Spulenkörper fixiert.A further modification is shown in FIG. 5. Two retaining pins 27 are each shaped so that they surround the connecting element 30 inserted between them in a U-shape. This connecting element 30 is then soldered to the winding end 9 in the slot 31 provided on both sides. A shoulder 28 also prevents the winding end from slipping down here. To fix the holding element 30, this is provided in this embodiment with a side tab 32 which lies in a side slot 33 of a holding pin 27 and fixes the connecting element 30 on the coil body by lateral bending.
