Description

In der Elektronik besteht ein großer Bedarf an Bauelementen, die auf der Oberfläche der gedruckten Schaltung durch Lötung montiert werden, sogenannte "surface mounted devices (SMD)". Dies ist für Widerstände und Kondensatoren bereits gelöst. Induktivitäten mit nur einer Wicklung sind ebenfalls bereits aus DE-GM 79 02 224 bekannt.In electronics there is a great need for components that are based on the Surface of the printed circuit can be mounted by soldering, so-called "surface mounted devices (SMD)". This is for resistors and capacitors already solved. Inductors with only one winding are also already out DE-GM 79 02 224 known.

Induktive Bauelemente, die mehrere Wicklungen und zusätzlich noch besondere hochfrequente Eigenschaften aufweisen müssen, wie z. B. Hochfrequenzübertrager (Impedanzwandler, Richtkoppler etc.) sind bisher noch nicht in SMD-Technik hergestellt worden.Inductive components that have multiple windings and additional special ones must have high-frequency properties, such as. B. high frequency transmitter (Impedance converters, directional couplers etc.) are not yet in SMD technology been made.

Die vorliegende Erfindung bezieht sich auf ein induktives Bauteil, das die bisherigen Hochfrequenzübertrager für die SMD-Technik verwendbar macht.The present invention relates to an inductive component that the makes previous high-frequency transmitters usable for SMD technology.

Beschreibung des erfindungsgemäßen BauteilsDescription of the component according to the invention

Eine Wanne 1 ist mit Aussparungen 2 für die Wickeldrahtenden 3 versehen und weist Ausnehmungen 4 am Boden auf, in denen die umgebogenen Wickeldrahtenden fixiert werden, um eine Kontaktierung mit der Oberfläche der gedruckten Schaltung zu gewährleisten.A trough 1 is provided with cutouts 2 for the winding wire ends 3 and has recesses 4 on the bottom in which the bent winding wire ends are fixed in order to ensure contact with the surface of the printed circuit.

In die Wanne 1 wird der bewickelte Kern 5 (hier ein 2-Lochkern) dergestalt eingefügt, daß die Wickeldrahtenden, die bereits verzinnt sind, in die Aussparungen 2 zu liegen kommen.The wound core 5 (here a 2-hole core) is inserted into the tub 1 in such a way that the winding wire ends, which are already tinned, come to rest in the cutouts 2 .

Zur Festlegung des Kerns 5 mit Wicklungen und der Wickeldrahtenden 3 wird von oben eine Kappe 6 eingedrückt, die selbsthaltend ist.To fix the core 5 with windings and the winding wire ends 3 , a cap 6 is pressed in from above, which is self-holding.

Die noch herausstehenden, verzinnten Wickeldrahtenden 3 werden in die Ausnehmungen 4 umgebogen.The still protruding, tinned winding wire ends 3 are bent into the recesses 4 .
