Abstract

The inductive component has two U-shaped laminated cores located side by side and each with its two limbs diverging so that when side by side only the ends of the adjacent limbs touch one another. The adjacent limbs form part of the core's centre arm and are enclosed in casting resin (3). A tube (4) passes over this centre arm and acts as a winding former for a toroidal coil (6). The whole of the assembly is held together with casting resin and to two lateral support blocks (7). The advantage of the inductive component lies in the simple manner in which it can be made.

Description

Induktives Bauteil mit Bandkern Die Erfindung bezieht sich auf ein induktives Bauteil mit Bandkern.Inductive component with tape core The invention relates to a inductive component with ribbon core.

Kerne für induktive Bauelemente lassen sich, wie bekannt, ohne Stanzarbeit und Stanzabfälle durch Aufwickeln eines Bandes aus magnetischem Werkstoff als sogenannte Bandkerne herstellen.Cores for inductive components can, as is known, without punching work and punching scraps by winding a tape of magnetic material as so-called Manufacture tape cores.

Es besteht die Aufgabe; ein induktives Bauteil zu schaffen, das einfach herzustellen ist, aus den oben erwähnten Grullden einen Bandkern enthält, der in etwa einem dreischenkligen Mantelkern in der üblichen, aus gestanzten Kernblechen aufgebauten Form ähneln soll.There is the task; Creating an inductive component is easy is to be produced, contains a tape core from the above-mentioned reasons, which in about a three-legged jacket core in the usual one made of punched core sheets should resemble the built-up shape.

Als Lösung der Aufgabe wird ein induktives Bauteil mit Bandkern angesehen, das dadurch gekennzeichnet ist, daß der Kern aus zwei benachbart angeordneten, sich mit ihren Mantelflächen berührenden Ringbandkernen gebildet ist, die die Form eines Mantelkerns mit Mittelschenkel bildend mit Gießharz umhüllt sind und daß ein längsgeteilter Wickelkörper um den zylindrischen Mittelschenkel drehbar zur Aufnahme der Wicklung vorgesehen ist.An inductive component with a tape core is seen as the solution to the problem, which is characterized in that the core consists of two adjacently arranged is formed with their lateral surfaces touching toroidal cores that have the shape of a Sheath core with middle legs are encased with casting resin and that a longitudinally divided Winding body rotatable around the cylindrical center leg to accommodate the winding is provided.

Durch den Verguß mit Gießharz unter Vakuum lassen sich die einzelnen Lagen der Ringbandkerne untereinander sowie die Ringbandkerne miteinander sehr fest verbinden, wobei gleichzeitig eine entsprechende Formgebung der Gießharzumhüllung, die den Forderungen der weiteren Verwendung des Kerns genau entspricht, vorgenommen werden kann.The individual Lay the toroidal cores to one another and the toroidal cores to one another very firmly connect, while at the same time a corresponding shape of the cast resin coating, which exactly corresponds to the requirements of the further use of the core can be.

Es wird vorzugsweise ein Gießharz mit hohem Füllstoffgehalt verwendet, was dem induktiven Bauteil hohe, mechanische und elektrische Festigkeit verleiht und etwa den gleichen thermischen Ausdehnungskoeffizienten wie das Kernmaterial aufweist.A casting resin with a high filler content is preferably used, which gives the inductive component high mechanical and electrical strength and about the same coefficient of thermal expansion as the core material having.

Weitere Merkmale und Vorteile ergeben sich aus der folgenden Beschreibung eines Ausführungsbeispiels in Verbindung mit den Zeichnungen.Further features and advantages emerge from the following description of an embodiment in conjunction with the drawings.

Figur 1 zeigt eine halbgeschnittene Seitenansicht eines induktiven Bauteils mit dreischenkligem Mantelkern.Figure 1 shows a half-sectioned side view of an inductive Component with a three-legged jacket core.

Der eigentliche Kern wird aus den zwei Ringbandkernen 1 und 1' gebildet, die benachbart angeordnet sich mit ihren Mantelflächen berühren. Unter dem Begriff "Ringbandkern" sind auch in ovaler oder annähernd rechteckiger Form gewickelte Kerne zu verstehen.The actual core is formed from the two toroidal cores 1 and 1 ', which are arranged adjacently touch with their lateral surfaces. Under the term "Toroidal tape cores" are also cores wound in an oval or approximately rectangular shape to understand.

Die derart angeordneten Ringbandkerne 1 und 1 sind mit Gießharz vergossen, wobei beim Gießverfahren eine derart gestaltete Gießform verwendet wird, daß ein einem der üblichen dreischenkligen Mantelkerne 2 ähnelndes Gebilde entsteht.The toroidal tape cores 1 and 1 arranged in this way are encapsulated with casting resin, wherein a mold designed in such a way is used in the casting process that a a structure resembling one of the usual three-legged sheath cores 2 arises.

Wie in Figur 2 zu sehen ist, weist die Gießharzumhüllung des Mittelschenkels 3 zylindrische Form auf, so daß sich darauf ein längs teilbarer Wickelkörper 4 mit Flanschen 5 anbringen und zum Aufbringen der Wicklung 6 drehen läßt.As can be seen in Figure 2, the cast resin coating of the center leg 3 cylindrical shape, so that there is a longitudinally divisible bobbin 4 with Attach flanges 5 and rotate 6 to apply the winding.

Die Verwendung der Gießharztechnik erlaubt auchdie Gießharzumhüllung 2 mit einem Befestigungsfuß 7 zu versehen, sowie die Ausnehmungen 8 zur Aufnahme von Befestigungs-und/oder Anschlußmitteln.The use of the cast resin technique also allows the cast resin coating 2 to be provided with a mounting foot 7, as well as the recesses 8 for receiving of fastening and / or connecting means.
