Description
Die Erfindung betrifft ein induktives Miniatur-Bauelement, insbesondere eine Antenne, mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1. Derartige Bauelemente sind grundsätzlich bekannt.The The invention relates to a miniature inductive component, in particular an antenna, having the features of the preamble of the claim 1. Such components are known in principle.
Bei bisher bekannten Bauelementen dieser Art besteht der Wickelkörper, auf welchen die drei Spulenwicklungen aufgebracht sind, mindestens teilweise aus Ferritmaterial, was herstellungstechnisch gewisse Schwierigkeiten aufwirft. Weiterhin ergeben sich bei der Herstellung oft Schwierigkeiten, indem einzelne Schritte des Herstellungsverfahrens, insbesondere das Aufbringen der dritten Spulenwicklung, von Hand durchgeführt werden müssen.at Previously known components of this type consists of the bobbin, on which the three coil windings are applied, at least partially made of ferrite material, which manufacturing certain difficulties raises. Furthermore, difficulties often arise in the production by taking individual steps of the manufacturing process, in particular the application of the third coil winding to be carried out by hand have to.
Der Erfindung liegt die Aufgabe zugrunde, ein induktives Miniatur-Bauelement, insbesondere eine Antenne, mit den im Oberbegriff des Patentanspruchs 1 beschriebenen Merkmalen so auszubilden, dass eine wenig aufwendige Herstellung möglich ist, die insbesondere vollautomatisch durchgeführt werden kann, die aber insbesondere einen sicheren Sitz der dritten Spulenwicklung gewährleistet.Of the Invention is based on the object, a miniature inductive component, in particular an antenna, with the in the preamble of the claim 1 described features such that a little expensive Production possible is, in particular, can be carried out fully automatically, but in particular ensures a secure fit of the third coil winding.
Die Lösung dieser Aufgabe geschieht erfindungsgemäß mit den Merkmalen aus dem kennzeichnenden Teil des Patentanspruchs 1. Vorteilhafte Weiterbildungen des erfindungsgemäßen Bauelements sind in den abhängigen Vorrichtungsansprüchen beschrieben. Verfahren zur automatischen Herstellung des erfindungsgemäßen Bauelements sind in den Verfahrensansprüchen 10 und 11 beschrieben.The solution This object is achieved according to the invention with the features of the characterizing part of claim 1. Advantageous developments of the device according to the invention are in the dependent apparatus claims described. Method for the automatic production of the component according to the invention are in the method claims 10 and 11 described.
Ein Grundgedanke der Erfindung besteht darin, den Wickelkörper des Bauelements insgesamt aus Kunststoff herzustellen und zwar derart, dass er innerhalb seiner Außenflächen einen Aufnahmeraum aufweist, in den ein als flaches Bauelement ausgebildeter Ferritkern vollautomatisch von oben eingesetzt oder von der Seite eingeschoben wird. Anschließend daran werden ebenfalls automatisch die drei Spulenwicklungen auf den Wickelkörper aufgebracht. Hierbei wird die dritte Spulenwicklung durch die am Wickelkörper angeordneten Führungselemente, welche Aufnahmetaschen bilden, durch welche die Windungen der dritten Spulenwicklung hindurchgeführt werden, in einem sicheren Sitz gehalten. Die Führungselemente sind in den Eckbereichen des Wickelkörpers angeordnet, so dass die dritte Spulenwicklung in diesen Bereichen besonders sicher geführt ist.One The basic idea of the invention is the winding body of the To manufacture a total of plastic and in such a way that he has one within his outer surfaces Has receiving space in which a trained as a flat component Ferrite core fully automatically inserted from above or from the side is inserted. Afterwards The three coil windings are also automatically applied to the winding body. Here, the third coil winding is arranged by the on the winding body Guide elements, which form receiving pockets through which the turns of the third Coil winding passed be kept in a secure seat. The guide elements are in the Corner areas of the winding body arranged so that the third coil winding in these areas very safe is.
Das erfindungsgemäße induktive Miniatur-Bauelement lässt sich rasch und wenig aufwendig auf entsprechend ausgestatteten Automaten herstellen.The inductive according to the invention Miniature device leaves quickly and inexpensively on appropriately equipped machines produce.
Im folgenden wird anhand er beigefügten Zeichnungen ein Ausführungsbeispiel für ein induktives Miniatur-Bauelement nach der Erfindung näher erläutert.in the The following will become apparent from the attached drawings an embodiment for a Inductive miniature device according to the invention explained in more detail.

In the latter case, the ferrite core then becomes one of the narrow sides pushed into the recording room.
