Priorität aus der französischen Patentanmeldung Nr. 71 01779 vom 20, Januar 1971Priority from French patent application No. 71 01779 of January 20, 1971

Die Neuerung betrifft einen Stromwandler, insbesondere Ferritkerntransformator mit M-förmigem Kern, wie solche unter der Bezeichnung l! Transduktoren" bekannt sind. In der Aasführung zahlreicher Schaltungen macht man von solchen kleinen Transformatoren immer mehr Gebrauch, Bei diesen ist gewöhnlich auf jedem Arm des Kerns eine Wicklung vorgesehen. Der Zusammenhalt der verschiedenen den Wandler bildenden Teile ist jedoch meist ziemlich schwierig zu erzielen. Hierfür benutzt man in der Regel verhältnismäßig schwerere Bügel, die durch Schrauben zusammengehalten sind.The innovation relates to a current transformer, in particular a ferrite core transformer with an M-shaped core, such as those under the designation l! Such small transformers are used more and more in the implementation of numerous circuits. These usually have a winding on each arm of the core you usually use relatively heavier brackets that are held together by screws.

Der Neuerung liegt die Aufgabe zugrunde, für solche Stromwandler Mittel vorzusehen, mit denen sich deren Montage schnell durchführen läßt und dessen einzelne Teile nach ihrem Zusammenbau sicher zusammengehalten werden.The innovation is based on the task for such current transformers Provide means with which their assembly can be carried out quickly and its individual parts after their assembly be held together securely.

Diese Aufgabe ist bei einem solchen Stromwandler gemäß der Steuerung dadurch gelöst, daß die auf den betreffenden Armen des Kerns angeordneten äußeren Spulenkörper an ihrem einen Ende mit der Befestigung am Sockel dienenden elastischen Haken und an Ihrem anderen Ende mit nutförmigen Laschen ausgestattet sind, in deren einander zugewandten Nuten eine Befestigungsfeder eingespannt ist, die mit ihrem mittleren Bereich unter Druck auf dem benachbarten Kernteil aufliegt. Diese auf dem Kern aufliegende Peder hält die einzelnen Teile des gesagten Stror.wanclers sicher zusammen, ohne da£ esWith such a current transformer, this task is in accordance with the control solved in that the arranged on the relevant arms of the core outer coil formers at one end to the attachment at the base serving elastic hooks and at your other end are equipped with groove-shaped tabs, in each of which facing grooves a fastening spring is clamped with its central area rests under pressure on the adjacent core part. This peder resting on the core holds the individual Parts of the said Stror.wanclers safely together without it

In the drawing, a ferrite core transformer in the structure proposed with the innovation is illustrated schematically in an embodiment selected for example. They show: FIG. 1 the transformer in elevation,

Fig. 3 in plan view.

Bei dem beispielsweise dargestellten Ferritkerntransformator ist der Ferritmagnetkern aus zwei Teilen la und Ib gebildet, von denen der Teil la drei Arme besitzt. Auf dem mittleren Arm und den beiden Seitenarmen des Kernteils la sitzt jeweils ein die betreffende Wicklung tragender Spulenkörper, nämlich der mittlere Spulenkörper 2 und die beiden seitlichen Spulenkörper 3 und 4, die jeweils aus Kunststoff gefertigt sind. Die beiden äußeren Spulenkörper 3 und 4 sind an ihrem einen Ende mit elastischen Haken 5, die ihrer Befestigung am Sockel 6 dienen, und an ihrem anderen Ende mit nutförmigen Laschen 7 ausgestattet, in deren einander zugewandten Nuten eine Befestigungsfeder 8 eingespannt ist, die mit ihrem mittleren Bereich unter Druck auf dem benachbarten Kernteil la aufliegt. Die Nut jeder der beiden Laschen 7 ist jeweils an einem Ende geschlossen, und in das andere, offene Ende der Nut läßt sich die Befestigungsfeder 8 beispielsweise eine Klaviersaite, ohne Schwierigkeit einführen.In the ferrite core transformer shown as an example the ferrite magnetic core is made up of two parts la and Ib, of which the part la has three arms. On the middle arm and the two side arms of the core part la each sits a bobbin carrying the relevant winding, namely the middle bobbin 2 and the two side bobbins 3 and 4, each made of plastic. the the two outer bobbins 3 and 4 are provided with elastic hooks 5 at one end, which fasten them to the base 6 serve, and at their other end with groove-shaped tabs 7 equipped, in the grooves facing each other a fastening spring 8 is clamped, which with its central area rests under pressure on the adjacent core part la. The groove of each of the two tabs 7 is at one end closed, and in the other, open end of the groove, the fastening spring 8, for example a piano string, introduce without difficulty.

Bei der dargestellten Ausführungsform sind die beiden äußeren Spulenkörper 3 und 4 einander genau gleich. Hieraus ergibt sich, daß die die betreffende Nut jeder Lasche schliessenden Bleche beiderseits der Längsachse des Gesamtaufbaus gelegen sind. Diese Anordnung ist besonders günstig, um die Befestigungsfeder 8 einzusetzen und in Lage zu halten. Unter diesen Bedingungen hält die Befestigungsfeder 8 durch ihren auf den Kern la ausgeübten Druck die verschiedenen "Teile des Wandleraufbaus wirkungsvoll zusammen. Dieser Gesamtaufbau ist noch vervollständigt durch Anschlußösen S3 cie dem Anschluß an eine zum Beispiel gedruckte Schaltung dienen.In the embodiment shown, the two outer bobbins 3 and 4 are exactly the same. It follows from this that the metal sheets closing the relevant groove of each tab are located on both sides of the longitudinal axis of the overall structure. This arrangement is particularly favorable for inserting the fastening spring 8 and holding it in position. Under these conditions, the pressure exerted on the core 1a effectively holds the fastening spring 8 together the various parts of the transducer structure. This overall structure is completed by connection lugs S 3 which are used for connection to a printed circuit, for example.
