Zur Anbringung induktiver Elemente, wie z. B. Entstördrosseln, werden diese auf einer Platine oder einem anderen geeigneten Träger angebracht und damit mit einem ferromagnetischen Kern versehen. Sowohl die Entstördrossel als auch der Kern werden als Einzelteile auf der Platine befestigt. Nachteilig bei einer derartigen Bestückung der Platine mit den Entstördrosseln ist, dass dabei mehrere Bauteile zusammenzusetzen sind, was zu einem erhöhten Arbeitsaufwand führt und durch ungenaue Positionierung des Kerns in der Entstördrossel einen schlechteren Toleranzbereich für die Induktivitätswerte zur Folge haben kann.For mounting inductive elements, such. As suppression chokes, these are mounted on a circuit board or other suitable carrier and thus provided with a ferromagnetic core. Both the suppression choke and the core are attached as individual parts on the board. A disadvantage of such assembly of the board with the suppression chokes is that several components are to be assembled, which leads to an increased workload and can result in poorer tolerance range for the inductance values due to inaccurate positioning of the core in the suppression choke.

Aus der
Obwohl diese Bauweise einen kompletten Zusammenbau der Entstördrossel vor ihrem Einbau in die Platine erlaubt, bleibt das Problem der Handhabung von mehreren Bauelementen beim Zusammenbau der Entstördrossel bestehen, was zur Erhöhung der Produktionskosten führt.Although this design allows a complete assembly of the suppression choke before its installation in the board, the problem of handling of multiple components in the assembly of the suppression choke remains, resulting in the increase of production costs.
Durch eine Vielzahl von elektronischen Bauteilen auf einer Platine zusammen mit einer Entstördrosselvorrichtung ist es aus Entwurfsgründen häufig erforderlich, die Abmessungen der Platine entsprechend groß zu wählen, so dass eine Miniaturisierung von Anlagen, in denen induktive Elemente verwendet werden, häufig nur in sehr geringem Ausmaße möglich ist.Due to a variety of electronic components on a board together with a suppression choke device, it is often necessary for design reasons to choose the dimensions of the board correspondingly large, so that miniaturization Of installations in which inductive elements are used, is often possible only to a very small extent.
Angesichts der zuvor genannten Probleme im Stand der Technik und des beleuchteten technischen Problemfeldes liegt der vorliegenden Erfindung die Aufgabe zu Grunde, ein induktives Element mit reduzierter Baugröße zu schaffen, das einfach herstellbar ist und dessen induktive Eigenschaften mit verbesserter Genauigkeit vorbestimmt werden können.In view of the aforementioned problems in the prior art and the illuminated technical problem field, the present invention, the object of the invention to provide an inductive element of reduced size, which is easy to manufacture and whose inductive properties can be predetermined with improved accuracy.
Gemäß einem Aspekt der vorliegenden Erfindung wird diese Aufgabe gelöst durch eine Entstördrosselvorrichtung gemäß Anspruch 1 und ein Verfahren zur Herstellung einer Entstördrosselvorrichtung zur Montage auf einer Platine gemäß Anspruch 17.According to one aspect of the present invention, this object is achieved by a suppression choke device according to
Die erfindungsgemäße Entstördrosselvorrichtung weist eine Entstördrossel mit einem Ringkern und ein Trägerbauteil zur Aufnahme der Entstördrossel auf. Hierbei ist das Trägerbauteil mit einem Grundkörper mit einer der Entstördrossel zugewandten Oberseite und einem an der Oberseite ausgebildeten Vorsprung versehen, wobei der Ringkern den Vorsprung zumindest teilweise umschließt.The suppression choke device according to the invention has a suppression choke with a toroidal core and a carrier component for receiving the suppression choke. Here, the support member is provided with a base body with a suppression choke facing the top and a projection formed on the top, wherein the toroidal surrounds the projection at least partially.
Diese Bauweise der erfindungsgemäßen Entstördrosselvorrichtung gewährleistet eine äußerst präzise Montage der Entstördrossel auf dem Trägerbauteil, wobei auch der Montagevorgang selbst auf Grund des teilweise Umschließens und damit der guten Positionierbarkeit der Entstördrossel vereinfacht ist.This design of Entstördrosselvorrichtung invention ensures an extremely precise assembly of the suppression choke on the support member, whereby the assembly process itself is simplified due to the partial enclosing and thus the good positioning of the suppression choke.
In einer weiteren Ausführungsform ist der Ringkern ein geschlossener Ringkern. Somit ist die Entstördrosselvorrichtung der vorliegenden Erfindung insbesondere auch für standardmäßige Ringkerne von Entstördrosseln gut geeignet.In a further embodiment, the toroidal core is a closed toroidal core. Thus, the suppression choke device of the present invention is particularly well suited for standard toroidal cores of suppression chokes.
In einer weiteren Ausführungsform weist die Entstördrossel wenigstens zwei um den Ringkern gewickelte Drosselspulen auf.In a further embodiment, the suppression choke has at least two inductors wound around the toroidal core.
In einer weiteren Ausführungsform sind die wenigstens zwei Drosselspulen bezüglich des Ringkems im Wesentlichen diametral gegenüberliegend angeordnet. Auf Grund dieser Bauweise lässt sich ein hohes Maß an Symmetrie der beiden Entstördrosseln erreichen, so dass in Kombination mit der erhöhten Fertigungsgenauigkeit und des vereinfachten Montageprozesses insgesamt eine kostengünstigere Lösung bei gleicher oder höherer Präzision bereitgestellt wird.In a further embodiment, the at least two choke coils are arranged substantially diametrically opposite one another with respect to the ring core. Due to this design, a high degree of symmetry of the two suppression chokes can be achieved, so that in combination with the increased manufacturing accuracy and the simplified assembly process, a more cost-effective solution with the same or higher precision is provided.
In einer weiteren Ausführungsform ist in dem Vorsprung eine Ausnehmung zur Aufnahme eines elektronischen Bauteils und/oder eines magnetischen Elements ausgebildet. Somit lässt sich wie bereits in Bezug zu dem zuvor beschriebenen Trägerbauteil eine entsprechend höhere Flexibilität bei der Verwendung der Entstördrosselvorrichtung erreichen, da beispielsweise eine wesentlich platzsparendere Anordnung auf einer Platine möglich ist und/oder die Einstellung der induktiven Eigenschaften der Entstördrossel auf Grund des Vorsehens eines entsprechenden magnetischen Elements möglich sind.In a further embodiment, a recess for receiving an electronic component and / or a magnetic element is formed in the projection. Thus, as already described in relation to the carrier component described above, a correspondingly higher flexibility in the use of the suppression choke device can be achieved since, for example, a considerably more space-saving arrangement on a circuit board is possible and / or the adjustment of the inductive properties of the suppression choke due to the provision of a corresponding one magnetic element are possible.
In weiteren vorteilhaften Ausführungsformen ist die Gestaltung des Trägerbauteils in der oben bereits beschriebenen Weise vorgesehen, so dass sich daraus auch die zuvor dargestellten Vorteile ergeben.In further advantageous embodiments, the design of the carrier component is provided in the manner already described above, so that there are also the advantages outlined above.
In einer weiteren vorteilhaften Ausführungsform sind mehrere Anschlussstifte vorgesehen, wobei zumindest ein Anschlussstift mit einem zu der Ausnehmung hinführenden Leiter verbunden ist. Auf Grund dieser Ausgestaltung kann eine entsprechende elektronische Komponente in der Ausnehmung effizient mit peripheren Bauelementen verbunden werden, so dass beispielsweise bereits vor der Montage der Entstördrosselvorrichtung auf einer Platine ein entsprechendes Bauteil in der Ausnehmung angeordnet sein kann.In a further advantageous embodiment, a plurality of connection pins are provided, wherein at least one connection pin is connected to a conductor leading to the recess. Due to this configuration, a corresponding electronic component in the recess can be efficiently connected to peripheral components, so that, for example, a corresponding component can already be arranged in the recess on a circuit board before the suppression choke device is mounted.
In weiteren vorteilhaften Ausführungsformen weist das elektronische Bauteil einen Kondensator und/oder eine Sicherung und/oder eine Diode auf.In further advantageous embodiments, the electronic component has a capacitor and / or a fuse and / or a diode.
Das erfindungsgemäße Verfahren zur Herstellung einer Entstördrosselvorrichtung zur Aufnahme auf einer Platine umfasst die Schritte: Anbringen ein Entstördrossel auf einem Trägerbauteil, das gemäß den zuvor beschriebenen Ausführungsformen ausgebildet sein kann. Einführen eines elektronischen Bauteils und/oder eines magnetischen Elements in die Ausnehmung und Fixieren des elektronischen Bauteils und/oder des magnetischen Elements durch Reibeschluss und/oder Klebung.The inventive method for producing a suppression choke device for receiving on a circuit board comprises the steps: attaching a suppression choke on a support member, which may be formed according to the embodiments described above. Introducing an electronic component and / or a magnetic element into the recess and fixing the electronic component and / or the magnetic element by frictional engagement and / or adhesion.
Mittels dieses Verfahrens lässt sich eine sehr effiziente und auch platzsparende Montage einer Entstördrosselvorrichtung verwirklichen, wobei insbesondere das Einbringen des Bauteils und/oder des magnetischen Elements vorteilhaft ausgenutzt werden kann, um damit ein besseres Leistungsverhalten und/oder geringere Montagekosten zu erreichen. Beispielsweise kann durch das Einbringen geeigneter elektronischer Komponenten das Gesamtverhalten der Entstördrossel verbessert werden, indem beispielsweise eine entsprechende Diode oder ein anderes Bauelement in unmittelbarer Nähe der die Entstördrossel bildenden Wicklungen angebracht werden kann. Somit lassen sich mögliche Spannungsspitzen, beispielsweise wenn das elektronische Bauteil als Freilaufdiode vorgesehen ist, in anderen Schaltungsbereichen der Platine gering halten. In anderen Ausführungsformen kann durch entsprechende Positionierung eines magnetischen Elements oder durch Auswahl und Vorsehen unterschiedlicher magnetischer Elemente die induktive Eigenschaft des Entstördrossel in gewünschter Weise verändert werden. Hierbei kann je nach Anwendung des gewünschten mechanischen Fixierens eine permanente oder eine lösbare mechanische Befestigung erreicht werden, so dass sich auch in dieser Hinsicht eine große Flexibilität im Hinblick auf die Montage sowie das Einstellen von Bauteileigenschaften ergibt.By means of this method, a very efficient and also space-saving installation of a suppression choke device can be realized, wherein in particular the introduction of the component and / or of the magnetic element can be advantageously exploited in order to achieve a better performance and / or lower assembly costs. For example, by introducing suitable electronic components, the overall behavior of the suppression choke can be improved by, for example, attaching a corresponding diode or another component in the immediate vicinity of the windings forming the suppression choke. Thus, possible voltage spikes, for example when the electronic component is provided as a freewheeling diode, can be kept low in other circuit areas of the circuit board. In other embodiments, by appropriate positioning of a magnetic element or by selecting and providing different magnetic elements, the inductive property of the suppression choke can be changed as desired. In this case, depending on the application of the desired mechanical fixing a permanent or a releasable mechanical attachment can be achieved, so that there is also in this respect a great deal of flexibility in terms of assembly and setting of component properties.
In einer weiteren vorteilhaften Ausführungsform umfasst das Verfahren das Einstellen der Induktivität des Entstördrossel durch Einbringen des magnetischen Elements und Anpassen der Position des magnetischen Elements in der Ausnehmung entsprechend einem vorgegebenen Sollwert. Wie zuvor bereits dargelegt ist, kann auf diese Weise das gewünschte Verhalten des Entstördrossel in flexibler Weise erreicht werden, wobei bei einer vorgegebenen Dimensionierung des Trägerbauteils sehr unterschiedliche Induktivitätswerte erreicht werden können, wobei jeder einzelne Wert dabei mit nur geringer Abweichung von einem zugehörigen Sollwert ermöglicht wird.In a further advantageous embodiment, the method comprises adjusting the inductance of the suppression choke by introducing the magnetic element and adjusting the position of the magnetic element in the recess in accordance with a predetermined desired value. As already explained above, in this way the desired behavior of the suppression choke can be achieved in a flexible manner, wherein given a dimensioning of the carrier component very different inductance values can be achieved, whereby each individual value is made possible with only a small deviation from an associated desired value ,
Erfindungsgemäß wird also in einem Aspekt eine Verlagerung elektronischer Bauteile oder magnetischer Bauteile in den Grundkörper eines Trägerbauteils erreicht, was eine Reduzierung einer direkt auf der Platine angeordneten Anzahl von elektronischen Bauelementen und schließlich eine Reduzierung der Größe der Platine selbst zur Folge hab kann.According to the invention, in one aspect, a shift of electronic components or magnetic components is achieved in the body of a support member, which can have a reduction of a directly arranged on the board number of electronic components and finally a reduction in the size of the board itself result.
Andererseits ergibt durch eine formschlüssige Ausbildung des Vorsprungs in dem zuvor dargelegten Trägerbauteil die Möglichkeit, dass ein Kern mit darauf angeordneten Drosselspulen im Wesentlichen in eine eindeutig definierbare Lage gebracht wird, die in hohem Maße reproduzierbar ist, so dass sich ein gewünschter Wert der Induktivitätseigenschaften gezielt einstellen lässt.On the other hand, the possibility that a core with choke coils arranged thereon is essentially brought into a clearly definable position which results in a clearly definable position of the projection in the carrier component set out above is highly reproducible, so that a desired value of the inductance can be set specifically.

Das Trägerbauteil 10 weist einen Grundkörper 1 mit einer Oberseite 3 und einer Unterseite 5 auf. In einer Ausführungsform kann der Grundkörper 1 eine im Wesentlichen rechteckige flache Bauform aufweisen, wobei wie in
Auf dem Trägerbauteil 10 ist eine Entstördrossel 9 befestigt, die in einer Ausführungsform einen Ringkern 13, etwa einen geschlossenen Ringkern, aufweist, der aus Ferrit aufgebaut ist, und um den eine oder mehrere Drosselspulen 15a und 15b herumgewickelt sind. In einer Ausführungsform sind mehrere Drosselspulen 15a, 15b vorgesehen, die bezüglich des Ringkems 13 einander diametral gegenüberliegend angeordnet sind. Die Entstördrossel 9 umschließt in einer Ausführungsform mit ihrem Ringkern 13 den Vorsprung 7, wobei die eine oder die mehreren Drosselspulen 15a und 15b beidseitig des Vorsprungs 7 und angrenzend an die kreisförmigen Ausläufe bzw. Ausbauchung des Vorsprungs 7 angeordnet sind. Somit ergibt sich eine formschlüssige Aufnahme des Vorsprungs 7 in dem Ringkern 13, wodurch wiederum eine reproduzierbare Positionierung der Entstördrossel 9 auf dem Trägerbauteil 10 erreicht wird. Insbesondere kann dabei die Form des Vorsprungs 7 so ausgebildet sein, dass auch durch die Bewicklung des Ringkems 13 entstehende Ausprägungen formschlüssig mit dem Vorsprung 7 im Eingriff sind.Mounted on the
Die Höhe des Vorsprungs 7 bezüglich der Oberseite 3 des Grundkörpers 1 entspricht in der gezeigten Ausführungsform in etwa der Höhe der Entstördrossel 9, wodurch eine recht kompakte Bauweise erreicht wird. In anderen Ausführungsformen kann die Höhe anders gewählt sein, so dass beispielsweise die Oberseite des Vorsprungs 7 deutlich unterhalb der Drosselspule 9 bleibt, wenn beispielsweise Ringkerne mit im Wesentlichen rechteckigen Querschnitt verwendet werden. In einer derartigen Anordnung ist eine präzise mechanische Fixierung auch mit einer geringen Höhe des Vorsprungs 7 verwirklichbar, so dass ggf. mit geringem Materialaufwand für den Vorsprung 7 eine gute Positionierung erreicht werden kann. In anderen Ausführungsformen kann der Vorsprung 7 über die Drosselspule 9 hinausragen, beispielsweise wenn das Vorsehen eines entsprechenden Deckels an der Oberseite des Vorsprungs 7 zur weiteren mechanischen Fixierung der Drosselspule 9 vorgesehen ist.The height of the

Besonders vorteilhaft stellt sich die Möglichkeit der Verschiebung eines Ferritelements bzw. magnetischen Elements (nicht gezeigt) in der Ausnehmung 11 dar, wodurch die Induktivitätseigenschaften der Entstördrossel wahlweise geändert werden können.The
