Abstract
Description
sUbstimmbare gedruckte Spule sind abstimnbare gedruckte Spulen bekannt, deren Leiterbahnen ein- oder beidseitig auf die Montageplatinen aufgebracht sind. Tunable printed coils are known tunable printed coils, whose conductor tracks are applied to the mounting boards on one or both sides.
Beidseitig aufgebrachte Leiterbahnen bringen den Vorteil, daß höhere Induktivitätswerte erreicht werden.Conductor tracks applied on both sides have the advantage that higher Inductance values can be achieved.
Ein gewisser Nachteil besteht jedoch bei der zuletzt genannten Ausführung darin, daß derartige Platinen hohe Herstellungskosten verursachen, da einerseits beim Auftreten eines Fehlers an einer der meist zahlreichen gedruckten Wicklungen die gesamte Platine unbrauchbar geworden ist.However, there is a certain disadvantage with the last-mentioned embodiment in that such boards cause high manufacturing costs, as on the one hand when a fault occurs on one of the mostly numerous printed windings the entire circuit board has become unusable.
Unter Durchplattieren versteht man im Zusammenhang mit zweiseitig kaschierten Printplatten das Metallisieren entsprechender Bohrungen in der Platine, um eine leitende Verbindung der gedruckten Wicklung der einen Seite mit der der anderen Seite zu erreichen.Plating through is understood in connection with two-sided laminated printed circuit boards the metallization of corresponding holes in the board, to conduct a conductive connection between the printed winding of one side and that of the to reach the other side.
Bei der erfindungsgemäßen Spule werden diese Nachteile versieden, da für jede Spule eine eigene kleine zweiseitig gedruckte Spule verwendet wird und die Hauptplatine in einfacher, kostensparender Weise mit nur einseitiger Kaschierung hergestellt werden kann.In the case of the coil according to the invention, these disadvantages are differentiated, because a separate small double-sided printed coil is used for each coil and the main board in a simple, cost-saving way with only one-sided lamination can be produced.
Die erfindungsgemäße Spule bringt zusätzlich den entscheidenden Vorteil, daß ohne die bisher erforderlichen Drahtbrücken sowohl Anzapfungen als auch Koppelwicklungen in einfacher Welse hergestellt werden können. Die mechanischen und elektrischen Verbindungen zur Hauptplatine werden in bekannt ter Weise durch die erforderliche Anzahl von Lötstiften hergestellt, Ein Spulenkörper, der in bekannter snap-in-Technik in eine innerhalb der gedruckten Wicklung vorgesehene Bohrung einrastet und der einen Gewindekern aus Ferrit oder Hochfrequenzeisen enthält, gestattet, die Induktivität der Spule stufenlos einzustellen.The coil according to the invention also has the decisive advantage that without the wire bridges previously required, both taps and coupling windings can be produced in simple catfish. The mechanical and electrical Connections to the motherboard are known in ter manner by the required Number of solder pins produced, A bobbin that is known in snap-in technology engages in a hole provided within the printed winding and which contains a threaded core made of ferrite or high-frequency iron, allows continuously adjust the inductance of the coil.
Bei den bisher bekanntgewordenen gedruckten Spulen bereitet die Abschirmung mit Bechern Schwierigkeiten, da die gedruckte Wicklung nicht innerhalb des Abschirmbechers liegen kann. Bei dem erfindungsgemäßen Spulenaufbau kann diese Schirmung vie bei einer mit Draht bzw. Litze gewickelten Spule durchgeführt werden. Eine magnetische Entkopplung mehrerer nebeneinander angeordneter Spulen ist also möglich.In the case of the previously known printed coils, the shielding prepares Difficulty with cans as the printed winding is not inside the shielding can can lie. In the case of the coil structure according to the invention, this shielding can be used in many ways a coil wound with wire or stranded wire. A magnetic one Decoupling of several coils arranged next to one another is therefore possible.
Nachfolgend wird die erfindungsgemäße Spule im einzelnen beschrieben: In Fig.I ist (1) eine beidseitig kupferkaschierte Platine, bei der das Wicklungsbild der Ober- und Unterseite in bekannter Weise durch Ätzen hergestellt wurde, (2) ist ein Durchbruch zur Aufnahme des Kernhalters (10). (3) , (5) , (6) und (7) sind Bohrungen, die der Aufnahme von Anschlußstiften (8) zur Verbindung der Spulenplatine (1) mit der Montageplatine (9) dienen. (4) ist eine durchplattierte Bohrung zur leitenden Verbindung der Wicklungsteile auf Ober- und Unterseite der Spulenplatine (1). Die spiralig geführte Hauptspule (3a) erstreckt sich auf der Oberseite von (3) bis (4) und auf der Unterseite von (4) bis (5). Eine eventuell erforderliche Koppelwicklung (6a) erstreckt sich von (6) bis (7). Die die Spulenanfänge und -enden bildenden Bohrungen (3),(5),(6) und (7) werden mit Anschlußstiften (8) zur Verbindung mit der Montageplatine (9) versehen, wie in Fig.II dargestellt.The coil according to the invention is described in detail below: In Fig.I (1) is a double-sided copper-clad board, in which the winding pattern the top and bottom was made in a known manner by etching, (2) is an opening for receiving the core holder (10). (3), (5), (6) and (7) are holes, the inclusion of connecting pins (8) for connecting the coil board (1) with serve for the mounting board (9). (4) is a plated through hole for the conductive Connection of the winding parts on the top and bottom of the coil board (1). the Spiral main coil (3a) extends on the top from (3) to (4) and on the bottom of (4) to (5). A possibly required coupling winding (6a) extends from (6) to (7). The ones forming the coil beginnings and ends Bores (3), (5), (6) and (7) are connected to pins (8) with the mounting board (9) provided, as shown in Fig.II.
Soll die Hauptspule (3a) eine Anzapfung aufweisen, so wird auch (4) mit einem Anschlußstift (8) versehen. Der vorzugsweise in snap-in-Technik ausgebildete, rohrförmige Kernhalter (10) ist mit Innengewinde oder inneren Längsstegen versehen, so daß ein Gewindekern (11) aus Ferrit oder Hochfrequenzeisen darin zügig verschraubt werden kann, um die Induktivität der gedruckten Spule stufenlos einzustellen. Ein Abschirmbecher (12) erzeugt im Bedarfsfall die gewünschte Schirmung.If the main coil (3a) is to have a tap, then (4) provided with a connecting pin (8). The preferably trained in snap-in technology, tubular core holder (10) is provided with an internal thread or internal longitudinal webs, so that a threaded core (11) made of ferrite or high-frequency iron is quickly screwed into it can be used to continuously adjust the inductance of the printed coil. A Shielding cup (12) creates the desired shielding if necessary.
