Abstract
Description
Die Erfindung betrifft eine Verbesserung der Ausführung des Spulenkörpers einer Kerndrossel, vorzugsweise einer Ringkerndrossel.The invention relates to an improvement in the execution of the Coil body of a core choke, preferably a toroidal core choke.
Ringkerndrosseln sind Bauelemente mit zumindest zwei um den ringartigen isolierten Kern gewickelten Drähten (Drahtwicklungen). Solche Bauelemente können z. B. zur Vermeidung von elektrischen Störungen in Industrieanlagen, Kfz-Steuergeräten, Unterhaltungselektronik oder in Haushaltsgeräten eingesetzt werden.Toroidal chokes are components with at least two around the ring-like insulated core wound wires (wire windings). Such components can e.g. B. to avoid electrical interference in industrial plants, vehicle control units, Consumer electronics or in household appliances be used.
Es ist bekannt, daß die Isolierung der Metalldrähte durch Verwendung eines Kupferlackdrahtes erreicht wird. Eine weitere Isolierungsmöglichkeit besteht darin, daß ein elektrisch leitender Kern selbst umsintert oder lackiert wird. Außerdem ist es bekannt, daß die Isolierung der Drahtwicklungen zum Kern dadurch gewährleistet werden kann, daß der Kern in einer dichten isolierenden Umhüllung aus Kunststoff angeordnet wird.It is known that the insulation of the metal wires by Use of enamelled copper wire is achieved. Another Insulation possibility is that an electrical conductive core is sintered or painted itself. Moreover it is known that the insulation of the wire windings for Core can be ensured that the core in a sealed insulating plastic cover becomes.
Die Potentialtrennung zwischen den Drahtwicklungen wird normalerweise mit Einlagen aus Pappe realisiert. Die Potentialtrennung kann außerdem durch eine zwei Drahtdurchführungen trennende Mittelwand erreicht werden.The electrical isolation between the wire windings is usually realized with cardboard inserts. The isolation can also be through a two wire feedthroughs separating middle wall can be reached.
Der Nachteil von vielen herkömmlichen, bei Herstellung der Ringkerndrosseln eingesetzten Umhüllungen besteht darin, daß diese keine definierten Greifflächen für einen Greifarm zur automatischen Bestückung aufweisen, weswegen nur eine manuelle Bestückung möglich ist. Es sind jedoch Ausführungen der Umhüllungen bekannt, in welchen die genannten Greifflächen vorgesehen sind. The disadvantage of many conventional ones when producing the Toroidal chokes used envelopes is that these have no defined gripping surfaces for a gripping arm have automatic assembly, which is why only a manual Equipping is possible. However, there are versions of the Enclosures known in which the gripping surfaces mentioned are provided.
Aus der Druckschrift DE 10013143 ist eine Kernumhüllung mit einem eingearbeiteten Haltesockel bekannt, der bei der Montage auf einer Leiterplatte in eine dafür vorgesehene Vertiefung oder Öffnung eingeführt wird, wodurch die Kerndrossel auf der Leiterplatte fixiert wird.From the document DE 10013143 a core sheathing is included a built-in mounting base known during assembly on a circuit board in a designated recess or opening is inserted, causing the core choke is fixed on the circuit board.
Die Befestigung der Drosselwicklungen am Drosselkern bzw. die Einhaltung des Rastermaßes, d. h. des Abstandes zwischen den elektrischen Anschlüssen, wird üblicherweise mit einem Verguß sichergestellt. Der Verguß dient zusätzlich zur Verbesserung der Wärmeleitfähigkeit des Bauteils und schützt den Ringkern vor Feuchtigkeit. Ein Verguß kann beispielsweise aus Klebemasse, Epoxiharz oder Polyurethan bestehen. Das Eingießen der Drosseln stellt jedoch einen zusätzlichen Arbeitsaufwand bei Herstellung der Bauteile dar und ist mit entsprechend hohen Kosten verbunden.The attachment of the choke windings to the choke core or Compliance with the grid dimension, d. H. the distance between the electrical connections, usually with a potting ensured. The potting also serves for improvement the thermal conductivity of the component and protects the toroid from moisture. A potting can be made, for example, from adhesive, Epoxy resin or polyurethane exist. Pouring the However, throttling adds extra work Manufacture of the components and is correspondingly high Associated costs.
Eine weitere schon bekannte Möglichkeit, die Drahtwicklungen um den Drosselkern anzubringen, ist eine lose Drahtanordnung um die Kernumhüllung. Die lose Drahtanordnung um den Kern ist von Nachteil, weil dabei die mechanische Instabilität der Konstruktion zur Labilität des Rastermaßes zwischen den elektrischen Anschlüssen und damit zu Kurzschlüssen führen kann.Another well-known option, the wire windings to attach the choke core is a loose wire arrangement around the core cladding. The loose wire arrangement around the core is disadvantageous because the mechanical instability of the Construction for the instability of the grid dimension between the electrical Connections and thus lead to short circuits.
Aus der Druckschrift DE 4216248 ist bekannt, zur Fixierung der Drahtwicklungen auf einer Kernumhüllung axiale Rillen auszubilden.From the publication DE 4216248 is known for fixation the wire windings have axial grooves on a core sheathing train.
Aufgabe der vorliegenden Erfindung ist es, eine Kerndrossel, die einen Drosselkern in Form eines geschlossenen Jochs aufweist (vorzugsweise Ringkerndrossel), so zu verbessern, daß bei radialer Anordnung der Drahtanschlüsse die Gefahr von Kurzschlüssen verringert und der Herstellungsprozeß vereinfacht wird.The object of the present invention is a core choke, which has a choke core in the form of a closed yoke (preferably toroidal choke), so that improve with radial arrangement of the wire connections, the risk of Short circuits are reduced and the manufacturing process is simplified becomes.

Zur Isolierung einzelner Wicklungen einer Drahtwicklung voneinander und zur Einhaltung eines Rastermaßes, womit der Abstand zwischen radial angeordneten elektrischen Anschlüssen des Bauelements gemeint ist, sind erfindungsgemäß -stirnseitig angeordnete Drahtführungseinrichtungen vorgesehen, welche als Bestandteil des Spulenkörpers ausgebildet sind. Die erfindungsgemäße, in den Spulkörper integrierte Drahtführung erspart einen zusätzlichen Aufwand für die Befestigung der Drahtwicklungen am Spulenkörper und gewährleistet eine besonders hohe Zuverlässigkeit der Kerndrossel im Hinblick auf Kurzschlüsse durch Sicherstellung des Rastermaßes.For isolating individual windings of a wire winding from each other and to maintain a grid dimension, with which the distance between radially arranged electrical connections of the component is meant, according to the invention, at the front arranged wire guide devices provided, which are formed as part of the bobbin.

Der Spulenkörper kann mit einer oder mit zwei, auf einander gegenüberliegenden Seiten des Spulenkörpers angeordneten Drahtwicklungen (durch die Drahtdurchführungen durch) umwickelt sein. Unter einer Drahtwicklung versteht man einen um den Drosselkern gewickelten Draht einschließlich aller Wicklungen zwischen zwei Anschlüssen an beiden Enden des Drahtes. Dieser Draht kann z. B. Kupferlackdraht, Alu-Draht, Aderleitung oder Metallitze sein. Die Isolierung der Wicklungen wird durch das Auftragen einer Lackschicht oder mittels eines isolierenden Kunststoffschlauchs erreicht.The named coil body is completed with a choke core or - for setting predefined magnetic properties of the component - partially filled out. The choke core consists of a for storing magnetic energy suitable material with magnetic properties, e.g. B. from Ferrites, iron powder or amorphous iron. The bobbin can be with one or with two, facing each other Wire windings arranged through the coil former (through the wire bushings are wrapped through).
