Description

Die vorliegende Erfindung betrifft einen elektrischen Schutzschalter gemäss Oberbegriff des Anspruches I.The present invention relates to an electrical circuit breaker according to the preamble of claim I.

Bei einem bekannten Schutzschalter dieser Art ist der bewegliche Kontaktteil auf einem Bolzen gelagert, der an einem Bügel befestigt ist, welcher am Rückschlussteil der magnetischen Auslöseeinrichtung befestigt ist (CH-A 479 950). An diesem Bügel ist das eine Ende der Wicklung der Auslösespule der magnetischen Auslöseeinrichtung angeschweisst. Diese bekannte Konstruktion ist trotz ihrer Einfachheit doch noch verhältnismässig aufwendig in der Herstellung und im Zusammenbauen.In a known circuit breaker of this type, the movable contact part is mounted on a bolt which is fastened to a bracket which is fastened to the back part of the magnetic tripping device (CH-A 479 950). One end of the winding of the release coil of the magnetic release device is welded onto this bracket. Despite its simplicity, this known construction is still relatively complex to manufacture and assemble.

Beim aus der GB-A 2 127 225 bekannten Schutzschalter ist am Joch der magnetischen Auslöseeinrichtung ein Halteteil befestigt, an dem neben dem beweglichen Kontaktteil auch der Schalterantrieb angebracht ist. Diese aus vielen einzelnen Bauteilen bestehende Konstruktion benötigt verhältnismässig viel Platz und verlangt zudem einen erheblichen Aufwand beim Zusammenbauen.In the case of the circuit breaker known from GB-A 2 127 225, a holding part is fastened to the yoke of the magnetic release device, to which the switch drive is attached in addition to the movable contact part. This construction, which consists of many individual components, requires a relatively large amount of space and also requires considerable assembly effort.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, einen Schutzschalter der eingangs genannten Art von einfacher und zuverlässig arbeitender Konstruktion zu schaffen, dessen magnetische Auslöseeinrichtung und der bewegliche Kontaktteil eine kompakte, möglichst wenig Platz beanspruchende Einheit bilden, die sich zudem auf einfache Weise zusammenbauen und mit andern Bauteilen in ein Schaltergehäuse einbauen lässt.The present invention has for its object to provide a circuit breaker of the type mentioned of simple and reliable working construction, the magnetic release device and the movable contact part form a compact unit that takes up as little space as possible, which are also easy to assemble and with other components in a switch housing.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teils des Anspruches I gelöst.According to the invention, this object is achieved by the features of the characterizing part of claim I.

Das Anbauen der den beweglichen Kontaktteil tragenden Halterung an die magnetische Auslöseeinrichtung, vorzugsweise an deren Auslösespule, kann dank der Schnappverbindung auf einfache Weise durch Aufstecken der Halterung samt beweglichem Kontaktteil auf die Auslöseeinrichtung erfolgen.The mounting of the holder carrying the movable contact part on the magnetic release device, preferably on its release coil, can be carried out in a simple manner thanks to the snap connection by plugging the holder together with the movable contact part onto the release device.

Eine besonders konstruktiv einfache und platzsparende Konstruktion ergibt sich dann, wenn die Verbindung zwischen Halterung und magnetischer Auslöseeinrichtung wie in den Ansprüchen 2 bis 5 definiert ausgebildet ist.A particularly structurally simple and space-saving construction results if the connection between the holder and the magnetic release device is designed as defined in claims 2 to 5.

Vorzugsweise ist die Halterung mit dem einen Ende der Wikklung der Auslösespule verbunden, während der bewegliche Kontaktteil auf einem an der Halterung angebrachten Lagerbolzen gelagert ist.The holder is preferably connected to one end of the winding of the trigger coil, while the movable contact part is mounted on a bearing pin attached to the holder.

Ein im Kurzschlussfall erwünschtes schnelles Oeffnen des Schaltkontaktes wird gemäss Anspruch 9 dadurch erreicht, dass die magnetische Auslöseeinrichtung einen Anker aufweist, der als auf den beweglichen Kontaktteil einzuwirken bestimmten Zuganker ausgebildet ist.A desired rapid opening of the switching contact in the event of a short circuit is achieved in accordance with claim 9 in that the magnetic release device has an armature which is designed as a tension rod to act on the movable contact part.

Eine besonders kompakte Bauweise des erfindungsgemässen Schutzschalters ergibt sich bei einer Ausbildung, wie sie in den Ansprüchen 12 und 13 definiert ist.A particularly compact design of the circuit breaker according to the invention results from an embodiment as defined in claims 12 and 13.

Im folgenden wird anhand der Zeichnung ein Ausführungsbeispiel des Erfindungsgegenstandes näher erläutert. Es zeigt rein schematisch:

  • Fig. 5 in side view and compared to Fig. I enlarged scale the movable contact part, and
  • 6 is a view of the holder for the movable contact part in the direction of arrow B in FIG. 3rd

In der Fig. I ist ein Teil einer Phase eines dreiphasigen Schutzschalters dargestellt. Die drei Phasen haben denselben, anhand der Figuren im folgenden nun zu beschreibenden Aufbau.I shows part of a phase of a three-phase circuit breaker. The three phases have the same structure, which will now be described with reference to the figures.

Der Schaltkontakt I jeder Phase wird durch einen feststehenden Kontaktteil 2 und einen beweglichen Kontaktteil 3 gebildet. Diesem Schaltkontakt ist eine magnetische Auslöseeinrichtung 4 sowie eine Löschkammer 5 mit Löschblechen 6 zugeordnet. Der feststehende Kontaktteil 2 ist mit einem Lichtbogenleitblech 7 einstückig ausgebildet, das sich zur Löschkammer 5 hin erstreckt. Der feststehende Kontaktteil 2 trägt ein Kontaktelement 8, das mit einem Kontaktelement 9 des beweglichen Kontaktteiles 3 zusammenwirkt. Dieses Kontaktelement 9 ist an einem Kontaktträger 10 befestigt, der mit zwei in einem Abstand und parallel zueinander verlaufenden Verbindungsteilen II, 12 verbunden ist. Von diesen Verbindungsteilen II, 12, welche über einen Steg 13 miteinander in Verbindung stehen, ist in Fig. I nur der Verbindungsteil 12 und in Fig. 5 nur der Verbindungsteil II sichtbar. Die beiden Verbindungsteile II, 12 sind drehbar auf einem Bolzen 14 gelagert, der an einer Halterung 15 aus elektrisch leiten dem Material, vorzugsweise Kupfer, befestigt ist. Die beiden Verbindungsteile II, 12 sind an ihren Enden über einen U-förmig ausgebildeten Bügel 16 miteinander verbunden. An diesem Bügel 16 ist einerseits ein Fortsatz 17 und andererseits eine Anschlagnase 18 ausgebildet, wie das aus den Fig. 2 und 5 besonders deutlich hervorgeht.The switching contact I of each phase is formed by a fixed contact part 2 and a movable contact part 3. A magnetic release device 4 and an arcing chamber 5 with arcing plates 6 are assigned to this switching contact. The fixed contact part 2 is formed in one piece with an arc guide plate 7, which extends to the arcing chamber 5. The fixed contact part 2 carries a contact element 8 which interacts with a contact element 9 of the movable contact part 3. This contact element 9 is fastened to a contact carrier 10, which is connected to two connecting parts II, 12 which are spaced apart and parallel to one another. Of these connecting parts II, 12, which are connected to one another via a web 13, only the connecting part 12 is visible in FIG. I and only the connecting part II in FIG. 5. The two connecting parts II, 12 are rotatably mounted on a bolt 14 which is attached to a holder 15 made of electrically conductive material, preferably copper. The two connecting parts II, 12 are connected to one another at their ends via a U-shaped bracket 16. On this bracket 16 on the one hand an extension 17 and on the other hand a stop lug 18 is formed, as can be seen particularly clearly from FIGS. 2 and 5.

Auf dem Bolzen 14 ist weiter drehbar ein Kopplungsglied 19 gelagert. Auf diesem Bolzen 14 sitzt weiter eine Torsionsfeder 20, die sich mit dem einen Ende 20a an einem Absatz 21 des Kopplungsgliedes 19 und mit dem andem Ende 20b an der Anschlagnase 18 des beweglichen Kontaktteiles 3 abstützt (Fig. 2). Am Kopplungsglied 19 ist weiter ein Anschlagteil 22 ausgebildet, mit dem sich das Kopplungsglied 19 unter der Wirkung der Torsionsfeder 20 am Fortsatz 17 des beweglichen Kontaktteiles 3 abstützt. Das Kopplungsglied 19 ist ferner mit einem abstehenden Nocken 23 versehen (Fig. 2), der in das gabelförmig ausgebildete Ende 24a eines Betätigungselementes 24 eingreift. Dieses Betätigungselement 24 bildet Teil des allen Phasen gemeinsamen Schalterantriebes, der in den Figuren nicht näher dargestellt ist.A coupling member 19 is rotatably mounted on the bolt 14. On this bolt 14 sits a torsion spring 20, which is supported with one end 20a on a shoulder 21 of the coupling member 19 and with the other end 20b on the stop lug 18 of the movable contact part 3 (Fig. 2). A stop part 22 is also formed on the coupling member 19, with which the coupling member 19 is supported on the extension 17 of the movable contact part 3 under the action of the torsion spring 20. The coupling member 19 is also provided with a protruding cam 23 (FIG. 2) which engages in the fork-shaped end 24a of an actuating element 24. This actuating element 24 forms part of the scarf common to all phases terantriebes, which is not shown in the figures.

Die magnetische Auslöseeinrichtung 4 weist eine Auslösespule 25 mit einem Spulenkörper 26 aus Kunststoff auf, der eine Wicklung 27 trägt. Letztere ist mit ihrem einen Ende 27a an einen L-förmigen Anschlussteil 28 angeschweisst, der als Anschlussklemme 29 ausgebildet ist. Das andere Ende 27b der Wicklung 27 ist an den einen Schenkel 15a der Halterung 15 angeschweisst. Dieser Schenkel 15a ist mit einem Lichtbogenleitelement 30 einstückig ausgebildet, das sich entlang der Auslösespule 25 erstreckt. Auf der der Wicklung 27 zugekehrten Seite ist am Lichtbogenleitelement 30 ein Blech 31 aus ferromagnetischem Material befestigt, das die Kommutierung eines beim Oeffnen des Schaltkontaktes I auf tretenden Lichtbogens auf das Lichtbogenleitelement 30 begünstigt.The magnetic release device 4 has a release coil 25 with a coil body 26 made of plastic, which carries a winding 27. The latter is welded with its one end 27a to an L-shaped connecting part 28, which is designed as a connecting terminal 29. The other end 27b of the winding 27 is welded to one leg 15a of the holder 15. This leg 15a is formed in one piece with an arc guiding element 30, which extends along the tripping coil 25. On the side facing the winding 27, a sheet 31 made of ferromagnetic material is fastened to the arc-guiding element 30, which promotes the commutation of an arc onto the arc-guiding element 30 when the switching contact I is opened.

Im Innern des Spulenkörpers 26 ist ein in Spulenlängsrichtung verschiebbarer Anker 32 angeordnet, der zwischen den Verbindungsteilen 11, 12 des beweglichen Kontaktteiles 3 verläuft und mit seinem Ende 32a an diesen Verbindungsteilen 11, 12 anzugreifen bestimmt ist. Zudem wirkt der Anker 32 mit diesem Ende 32a weiter mit einem Auslöseelement 33 zusammen, das Teil der Schalterauslöseeinrichtung bildet.Arranged in the interior of the coil body 26 is an armature 32 which can be displaced in the longitudinal direction of the coil and which runs between the connecting parts 11, 12 of the movable contact part 3 and is intended to engage with these connecting parts 11, 12 with its end 32a. In addition, the armature 32 cooperates with this end 32a with a trigger element 33, which forms part of the switch triggering device.

Mit dem einen Flansch 26a des Spulenkörpers 26 sind zwei vom Spulenkörper 26 wegragende Halteglieder 34, 35 einstükkig ausgebildet, die in einem Abstand und parallel zueinander verlaufen, wie das insbesondere aus Fig. 4 ersichtlich ist. Jedes Halteglied 34, 35 ist mit einer federnden Zunge 36 bzw. 37 versehen. Die beiden Zungen 36, 37 sind etwas gegeneinander zu, d.h. nach innen gebogen. Zwischen den Enden dieser Zungen 36, 37 und dem Flansch 26a des Spulenkörpers 26. ist der Schenkel 15a der Halterung 15 festgeklemmt. Mit dem andern Schenkel 15b, der gegenüber dem Schenkel 15a abgewinkelt ist, sitzt die Halterung 15 auf dem Halteglied 35, wie das insbesondere aus Fig. 3 hervorgeht. Zudem hintergreift dieser Schenkel 15b der Halterung 15 mit einem Fortsatz 38 eine vorspringende Nase 39, die am Halteglied 35 ausgebildet ist. Durch die beiden elastisch ausbiegbaren Zungen 36, 37 wird die Halterung 15 in der Art einer Schnappverbindung am Spulenkörper 26 gehalten. Eine Verschiebung der Halterung 15 quer zur Wirkrichtung der Zungen 36, 37, d.h. quer zur Spulenlängsachse 26', wird einerseits durch die Auflage des Schenkels 15b auf dem Halteglied 35 und andererseits durch den die Nase 39 hintergreifenden Fortsatz 38 verhindert.With the one flange 26a of the coil body 26, two holding members 34, 35 projecting from the coil body 26 are formed in one piece, which run at a distance and parallel to one another, as can be seen in particular from FIG. 4. Each holding member 34, 35 is provided with a resilient tongue 36 and 37, respectively. The two tongues 36, 37 are slightly towards each other, i.e. bent inwards. The leg 15a of the holder 15 is clamped between the ends of these tongues 36, 37 and the flange 26a of the coil body 26. With the other leg 15b, which is angled relative to the leg 15a, the holder 15 sits on the holding member 35, as can be seen in particular from FIG. 3. In addition, this leg 15b of the holder 15 engages with a projection 38 a projecting nose 39 which is formed on the holding member 35. By means of the two elastically deflectable tongues 36, 37, the holder 15 is held on the coil body 26 in the manner of a snap connection. A displacement of the bracket 15 transversely to the direction of action of the tongues 36, 37, i.e. transverse to the longitudinal axis 26 'of the coil is prevented on the one hand by the support of the leg 15b on the holding member 35 and on the other hand by the extension 38 engaging behind the nose 39.

In den beiden Haltegliedern 34, 35 sind sich in Richtung der Längsachse 26' des Spulenkörpers 26 erstreckende Längs schlitze 40 (Fig. 3) vorhanden, in die vom Anker 32 seitlich wegragende Fortsätze 41 (Fig. I) eingreifen. Durch diese Längsschlitze 40 wird der Anker 32 geführt.In the two holding members 34, 35 extending in the direction of the longitudinal axis 26 'of the bobbin 26 extending longitudinal slots 40 (FIG. 3) are present, in which extensions 32 projecting laterally from the armature 32 (FIG. I) engage. The armature 32 is guided through these longitudinal slots 40.

In Fig. ist der Schalter mit geschlossenem Schaltkontakt I gezeigt. Zum Oeffnen dieses Schaltkontaktes I wird das Betätigungselement 24 im Gegenuhrzeigersinn verschwenkt. Das hat ein Drehen des Kopplungsgliedes 19 im Uhrzeigersinn zur Folge. Da das Kopplungsglied 19 wie bereits erwähnt mit dem Anschlagteil 22 am Fortsatz 17 des beweglichen Kontaktteiles 3 anliegt, wird bei dieser Drehbewegung des Kopplungsgliedes 19 der bewegliche Kontaktteil 3 sofort mitgenommen und vom feststehenden Kontaktteil 2 wegbewegt. Somit werden die beiden Kontaktelemente 8, 9 rasch voneinander getrennt. Ein sich beim Oeffnen des Schaltkontaktes I bildender Lichtbogen wandert sofort auf die Lichtbogenleitbleche 7 und 30.The switch with closed switch contact I is shown in FIG. To open this switch contact I, the actuating element 24 is pivoted counterclockwise. This has the result that the coupling member 19 is rotated clockwise. Since, as already mentioned, the coupling member 19 rests with the stop part 22 on the extension 17 of the movable contact part 3, during this rotational movement of the coupling member 19 the movable contact part 3 is immediately taken along and moved away from the fixed contact part 2. The two contact elements 8, 9 are thus quickly separated from one another. An arc that forms when switching contact I opens immediately migrates to arc guide plates 7 and 30.

Zum Schliessen des Schaltkontaktes I wird das Betätigungselement 24 im Uhrzeigersinn verschwenkt, was eine Drehung des Kopplungsgliedes 19 im Gegenuhrzeigersinn zur Folge hat. Ueber die Torsionsfeder 20 wird diese Drehbewegung des Kopplungsgliedes 19 auf den beweglichen Kontaktteil 3 übertragen. In geschlossener Stellung des Schaltkontaktes wird der bewegliche Kontaktteil 3 durch die als Kontaktdruckfeder wirkende Torsionsfeder 20 gegen den feststehenden Kontaktteil 2 gedrückt.To close the switching contact I, the actuating element 24 is pivoted clockwise, which results in a rotation of the coupling member 19 in the counterclockwise direction. This torsional movement of the coupling member 19 is transmitted to the movable contact part 3 via the torsion spring 20. In the closed position of the switching contact, the movable contact part 3 is pressed against the fixed contact part 2 by the torsion spring 20 acting as a contact pressure spring.

Im Falle eines Kurzschlusses spricht die magnetische Auslöseeinrichtung 4 an, was zur Folge hat, dass der Anker 32 zurückgezogen wird. Da dessen Ende 32a wie bereits beschrieben an den Verbindungsteilen 11, 12 des beweglichen Kontaktteiles 3 angreift, wird durch diese Rückwärtsbewegung des Ankers 32 der bewegliche Kontaktteil 3 vom fest stehenden Kontaktteil 2 wegbewegt und der Schaltkontakt I aufgerissen. Gleichzeitig wird das Auslöseelement 33 mitgenommen, wodurch der Schalterauslösemechanismus betätigt wird.In the event of a short circuit, the magnetic tripping device 4 responds, with the result that the armature 32 is withdrawn. Since its end 32a, as already described, engages the connecting parts 11, 12 of the movable contact part 3, this backward movement of the armature 32 moves the movable contact part 3 away from the fixed contact part 2 and the switching contact I is torn open. At the same time, the trigger element 33 is carried along, whereby the switch trigger mechanism is actuated.

Durch dieses direkte Einwirken des Ankers 32 auf den beweglichen Kontaktteil 3 wird der Schaltkontakt I rasch geöffnet. Der sich dabei bildende Lichtbogen kommutiert wie bereits erwähnt auf die Lichtbogenleitbleche 7 und 30, was zur Folge hat, dass über die Kontaktteile 2, 3 sehr rasch nach Auftreten eines Kurzschlusses kein Strom mehr fliesst. Auf diese Weise wird vermieden, dass der Kurzschlussstrom zu lange über den Bolzen 14 fliesst, so dass dieser nicht überbeansprucht wird.This direct action of the armature 32 on the movable contact part 3 opens the switching contact I quickly. As already mentioned, the resulting arc commutates on the arc guide plates 7 and 30, which has the consequence that no more current flows via the contact parts 2, 3 very quickly after a short circuit has occurred. In this way it is avoided that the short-circuit current flows over the bolt 14 for too long, so that it is not overstressed.

Das Zusammenbauen der magnetischen Auslöseeinrichtung 4 und der Halterung 15 für den beweglichen Kontaktteil 3 kann auf sehr einfache Weise durch Aufstecken der Halterung 15 auf die magnetische Auslöseeinrichtung 4 in Richtung der Längsachse 26' des Spulenkörpers 26. Im Zuge dieses Aufsteckens werden die federnden Zungen 36, 37 etwas zurückgebogen und schnappen dann in ihre Ruhelage zurück, in der sie wie bereits erwähnt den Schenkel 15a der Halterung 15 gegen den Flansch 26a des Spulenkörpers 26 drücken und somit die Halterung 15 festhalten. Gleichzeitig kommt der Fortsatz 38 am Schenkel 15b der Halterung 15 mit der vorspringenden Nase 39 am Halteglied 35 zum Zusammenwirken.The assembly of the magnetic release device 4 and the holder 15 for the movable contact part 3 can be done very simply by plugging the holder 15 onto the magnetic release device 4 in the direction of the longitudinal axis 26 'of the coil body 26. In the course of this connection, the resilient tongues 36, 37 slightly bent back and then snap back into their rest position, in which, as already mentioned, they press the leg 15a of the holder 15 against the flange 26a of the coil former 26 and thus hold the holder 15 in place. At the same time, the extension 38 on the leg 15b of the holder 15 interacts with the projecting nose 39 on the holding member 35.

Die aus magnetischer Auslöseeinrichtung 4, Halterung 15, Bolzen 14, beweglichem Kontaktteil 3, Kopplungsglied 19 und Torsionsfeder 20 bestehende Baueinheit ist von sehr kompakter und platzsparender Bauweise und lässt sich nicht nur sehr einfach zusammenbauen, sondern auch rasch und ohne Schwierigkeiten in das Schaltergehäuse einbauen, in welchem die entsprechenden Baueinheiten für die anderen Phasen sowie weitere Bauteile, wie beispielsweise die Bimetallauslöser und der gemeinsame Schalterantrieb, untergebracht sind.The assembly consisting of magnetic release device 4, holder 15, bolt 14, movable contact part 3, coupling member 19 and torsion spring 20 is of a very compact and space-saving design and is not only very easy to assemble, but also can be installed quickly and without difficulty in the switch housing, in which the corresponding units for the other phases and other components le, such as the bimetallic release and the common switch drive, are housed.

Es versteht sich, dass der beschriebene Schutzschalter in verschiedenen Teilen auch anders als wie beschrieben und dargestellt ausgebildet werden kann. Von den verschiedenen möglichen Varianten sei im folgenden nur auf einige wenige hingewiesen.It goes without saying that the circuit breaker described can also be designed in different parts differently than as described and illustrated. Only a few of the various possible variants are mentioned below.

Wie aus Fig. 3 und insbesondere der Fig. 6 hervorgeht, kann am einen Halteglied 34 oder 35 oder an beiden Haltegliedern 34 und 35 eine vorspringende Rippe 42 vorgesehen werden, die sich in Richtung der Längsachse 26' des Spulenkörpers 26 erstreckt. Diese Rippe 42 greift in eine seitlich am Schenkel 15a der Halterung 15 vorgesehene Aussparung 43 ein. Entsprechend kann an der gegenüberliegenden Seitenkante des Schenkels 15a eine zweite Aussparung vorgesehen werden, in die eine Rippe am Halteglied 35 eingreift. Durch die in die Aussparung 43 eingreifende Rippe 42 wird eine Verschiebung der Halterung 15 in einer Richtung quer zur Wirkrichtung der Zungen 36, 37, d.h. quer zur Spulenkörperlängsachse 26', verhindert. Damit wird die durch den Fortsatz 38 und die Nase 39 erzielte Wirkung unterstützt.As can be seen from FIG. 3 and in particular from FIG. 6, a projecting rib 42 can be provided on one holding member 34 or 35 or on both holding members 34 and 35, which extends in the direction of the longitudinal axis 26 'of the bobbin 26. This rib 42 engages in a recess 43 provided laterally on the leg 15a of the holder 15. Correspondingly, a second recess can be provided on the opposite side edge of the leg 15a, into which a rib engages on the holding member 35. The rib 42 engaging in the recess 43 causes a displacement of the holder 15 in a direction transverse to the effective direction of the tongues 36, 37, i.e. transverse to the bobbin longitudinal axis 26 'prevented. This supports the effect achieved by the extension 38 and the nose 39.

Dieselbe Wirkung liesse sich auch erreichen, wenn am Schenkel 15a eine vorspringende Nase vorgesehen würde, die in eine Führungsnut am einen Halteglied eingreift.The same effect could also be achieved if a projecting nose were provided on the leg 15a, which engages in a guide groove on a holding member.

Die Schnappverbindung zwischen der Halterung 15 und der Auslöseeinrichtung 4 kann auch eine andere als die gezeigte Ausgestaltung erfahren. So ist es zum Beispiel denkbar, die federnden Zungen 36, 37 statt an den Haltegliedern 34, 35 auszubilden, am Schenkel 15a der Halterung 15 vorzusehen. In diesem Falle sind an den Haltegliedern 34, 35 Vor sprünge vorzusehen, an denen die Zungen am Schenkel 15a anstehen und die ein Verschieben der Halterung 15 verhindern.The snap connection between the holder 15 and the triggering device 4 can also experience a configuration other than that shown. For example, it is conceivable to provide the resilient tongues 36, 37 on the leg 15a of the holder 15 instead of on the holding members 34, 35. In this case, jumps are to be provided on the holding members 34, 35, on which the tongues abut the leg 15a and prevent the holder 15 from moving.

Im weitern ist es denkbar, nur ein Halteglied 35 vorzusehen und die Halterung 15 an einer andern Stelle auf geeignete Weise zu halten, z.B. mittels eines Fortsatzes am Schenkel 15a, der ein Arretierglied am Flansch 26a des Spulenkörpers 26 untergreift.Furthermore, it is conceivable to provide only one holding member 35 and to hold the holder 15 in a suitable manner at another location, e.g. by means of an extension on the leg 15a, which engages under a locking member on the flange 26a of the bobbin 26.
