Description

Elektrische RingkernspuleElectric toroidal coil

Die Erfindung betrifft eine elektrische Ringkernspule mit ein und gegebenenfalls mehreren Windungen und mit einer gegebenenfalls mit Anschlußstiften für Leiterplatten bestückten Isolierstoffträgerplatte. Diese, auch als Anschlußträgerplatte bezeichnete Isolierstoffträgerplatte dient als Auflager für den bewickelten Ringkern der Spule und enthält zum Beispiel im Rastermaß ausgerichtete Anschlußstifte, mittels deren die Isolierstoffträgerplatte samt Ringkernspule auf Leiterplatten oder sonstige Anschlußelemente aufsetzbar ist.The invention relates to an electrical toroidal core coil with a and possibly several turns and with one possibly with connecting pins for printed circuit boards equipped with insulating material carrier plate. This, also as a connection carrier plate The insulating material carrier plate designated serves as a support for the wound toroidal core the coil and contains, for example, terminal pins aligned in the grid, by means of the insulating material carrier plate including the toroidal core coil on circuit boards or other Connection elements can be placed.

Die Bewicklung der Ringkerne erfolgte bislang mit einem der an sich bekannten Wickelverfahren, zum Beispiel mittels drahtgespeister Ringmagazine, die durch die Kernbohrung laufen, wobei die rotationssymmetrischen Achsen des Ringmagazins und des rotierenden Ringkernes vorzugsweise senkrecht zueinander ausgerichtet sind. Die diesem Wickelvorgang nachgeschaltete Montage des bewickelten Ringkernes auf der Isolierstoffträgerplatte bedarf eines gesonderten Arbeitsganges.The winding of the toroidal cores has so far been done with one of the known winding method, for example by means of wire-fed ring magazines, the run through the core bore, the rotationally symmetrical axes of the ring magazine and the rotating toroidal core are preferably aligned perpendicular to one another. The assembly of the wound toroidal core following this winding process the insulating material carrier plate requires a separate operation.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Ringkernspule der eingangs genannten Art vorzuschlagen, die eine kostensparende Kombination der beiden Arbeitsgänge, also eine nur mit geringem Aufwand verbundene Bewickelung der Ringkerne und ihrer Montage auf der Isolierstoffträgerplatte ermöglicht.The present invention is based on the object of a toroidal core coil of the type mentioned to propose a cost-saving combination of two work steps, so a winding of the Allows toroidal cores and their assembly on the insulating support plate.

Zur Lösung dieser Aufgabe schlägt die Erfindung bei einer elektrischen Ringkernspule der eingangs erwähnten Art vor, daß der Ringkern auf der Isolierstoffträgerplatte aufliegt, daß die Isolierstoffträgerplatte längs beider Ringkernmantelflächen Bohrungen aufweist, deren gegenüberliegende Paare auf der zum Ringkern abgekehrten Seitenfläche der Isolierstoffträgerplatte jeweils durch einen Leiter, insbesondere eine Leiterbahn miteinander verbunden sind, und daß diese Leiter durch Bügel aus elektrisch leitendem Werkstoff, zum Beispiel Messingbügel, die auf den Ringkern aufgeschoben und mit ihren Enden in den entsprechenden Bohrungen benachbarter Leiter verankert sind, zu Windungen ergänzt sind.To solve this problem, the invention proposes an electrical one Toroidal core coil of the type mentioned above that the toroidal core on the insulating carrier plate rests that the Isolierstoffträgerplatte along both toroidal core surface bores has, the opposite pairs of which on the side face facing away from the toroidal core the insulating material carrier plate in each case by a conductor, in particular a conductor track are interconnected, and that these conductors are electrically conductive by means of brackets Material, for example brass stirrups, which are pushed onto the toroid and with their ends are anchored in the corresponding holes in adjacent conductors, are added to turns.

Zur Schaffung dieser Leiter, insbesondere Leiterbahnen, sind in besonderem Maße kupferkaschierte Isolierstoffplatten geeignet, aus denen in bekannter Weise die Leiterbahnen herausgearbeitet werden können.To create these conductors, especially conductor tracks, are special Dimensions copper-clad insulating panels suitable from which in a known manner the conductor tracks can be worked out.

Als Bügel sind bevorzugt U-förmige Bügel geeignet, deren, zum Beispiel mittels einer Bestückvorrichtung in die Bohrungen eingeführten Enden durch Schwall-, Tauchlöten oder Schweißen mit den Leiterbahnenden elektrisch kontaktiert werden.U-shaped brackets are preferably suitable as brackets, for example ends introduced into the bores by means of a fitting device by means of surge, Dip soldering or welding can be electrically contacted with the conductor track ends.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles näher erläutert. Es zeigt: Fig. 1 eine Draufsicht auf eine bewickelte Ringkernspule, die'auf eine Isolierstoffträgerplatte aufgesetzt ist, Fig. 2 in schematischer und perspektivischer Darstellung die Fertigung der Ringkernspule nach Fig. 1.The invention is explained below using an exemplary embodiment explained in more detail. It shows: FIG. 1 a plan view of a wound toroidal core coil, die'auf an Isolierstoffträgerplatte is placed, Fig. 2 in schematic and perspective illustration of the manufacture of the toroidal core coil according to FIG. 1.

Die Ringkernspule nach Fig. 1, 2 besitzt eine Isolierstoff- bzw. Anschlußträgerplatte 2, die mit im Rastermaß ausgerichteten Anschlußstiften 3 für Leiterplatten bestückt ist. Auf dieser Isolierstoffträgerplatte liegt ein Ringkern 1, insbesondere Ferrit-Ringkern auf. Die Isolierstoffträgerplatte 2 weist längs beider Mantelflächen des Ringkernes 1 Bohrungen 4 bzw. 5 auf, deren jeweils gegenüberliegende Paare 4, 5 auf der zum Ringkern 1 abgekehrten Seitenfläche der Isolierstoffträgerplatte 2 durch je eine strichliniert angedeutete Leiterbahn 7 miteinander elektrisch leitend verbunden sind.The toroidal core coil according to FIGS. 1, 2 has an insulating material or connection carrier plate 2, which are equipped with connecting pins 3 for printed circuit boards aligned in the grid is. A toroidal core 1, in particular a ferrite toroidal core, lies on this insulating material carrier plate on. The insulating material carrier plate 2 has along both lateral surfaces of the toroidal core 1 holes 4 and 5, their respective opposing pairs 4, 5 on the for Toroidal core 1 facing away from the side surface of the insulating material carrier plate 2 by one each Conductor track 7 indicated by dashed lines connected to one another in an electrically conductive manner are.

Im gezeigten Ausführungsbeispiel sind zwei Anschlußstifte 3 über gleichfalls strichliniert dargestellte Leiterbahnen 8 bzw.9, die sich auf der gleichen Seitenfläche der Isolierstoffträgerplatte 2 befinden, mit Bohrungen 4 verbunden, die dem Wickelanfang bzw. -ende zugeordnet sind.In the embodiment shown, two connecting pins 3 are also over Conductor tracks 8 and 9 shown in dashed lines, which are located on the same side surface the Isolierstoffträgerplatte 2 are, connected with holes 4, the beginning of the winding or end are assigned.

Die Leiterbahnen 7 sind durch Bügel 6, zum Beispiel aus Messing, die auf den Ringkern 1 aufgeschoben und mit ihren Enden 10, 11 in den entsprechenden Bohrungen 4, 5 benachbarter Leiterbahnen 7, 7 verankert sind, zu Windungen ergänzt. Die elektrische Kontaktierung der Leiterbahnen 7, 8, 9 und der Bügelenden 10, 11 mit diesen Leiterbahnen erfolgt in einem Arbeitsgang, zum Beispiel durch Tauch- oder Schwallöten. Denkbar ist auch eine Verbindung der Bügelenden mit den Leiterbahnen mittels Schweißen, wobei zweckmäßigerweise das Eindrücken der Bügel 6 in die Bohrungen 4, 5 synchron mit dem Schweißvorgang für diese beiden Kontaktstellen verknüpft wird.The conductor tracks 7 are through brackets 6, for example made of brass, the pushed onto the toroidal core 1 and with their ends 10, 11 in the corresponding Bores 4, 5 of adjacent conductor tracks 7, 7 are anchored, added to turns. The electrical contacting of the conductor tracks 7, 8, 9 and the temple ends 10, 11 with these conductor tracks takes place in one operation, for example by immersion or wave soldering. A connection of the temple ends with the conductor tracks is also conceivable by means of welding, expediently pressing the bracket 6 into the bores 4, 5 is linked synchronously with the welding process for these two contact points.
