Description

Die Erfindung betrifft einen Hochfrequenzübertrager nach dem Oberbegriff des Anspruchs 1.The invention relates to a high frequency transmitter according to the preamble of claim 1.

Aus der DE 37 21 956 A1 ist ein derartiger Hochfrequenzübertrager für SMD-Montage bekannt. Diesem Bauteil, das für vollautomatische Fertigung konzipiert ist, haften noch Nachteile an, die durch die neue Ausgestaltung des Kerns aus magnetisch leitfähigem Material vermieden werden.DE 37 21 956 A1 describes such a high-frequency transmitter for SMD assembly known. This component, which is designed for fully automatic production, still have disadvantages caused by the new design of the Core made of magnetically conductive material can be avoided.

Der Hauptnachteil des Übertragers nach der DE 37 21 956 A1 und somit das der Erfindung zugrunde liegende Problem ist, daß der mit der Kontaktträgerplatte verbundene Kern an seiner Unterseite nicht bewickelt werden kann, obwohl dies aus elektrischen Gründen wünschenswert ist.The main disadvantage of the transformer according to DE 37 21 956 A1 and thus the problem underlying the invention is that of the contact carrier plate connected core cannot be wound on its underside, although this is desirable for electrical reasons.

Dieses Problem wird durch die im Anspruch 1 aufgeführten Merkmale gelöst.This problem is solved by those listed in claim 1 Features resolved.

Eine vorteilhafte Ausgestaltung der Erfindung ist in Anspruch 2 angegeben.An advantageous embodiment of the invention is in claim 2 specified.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.

Wie aus der Abb. 1 ersichtlich ist, weist der Kern (1), der die Bohrungen (2) für die Wicklungen (3) enthält, gegenüber der Kontaktträgerplatte (4), auf die der Kern (1) mittels der Klebefläche (5) aufgeklebt ist, an den Seiten soweit einen Abstand (6) auf, daß dort die Drähte der Wicklung (3) untergebracht werden können.As can be seen from Fig. 1, the core ( 1 ), which contains the bores ( 2 ) for the windings ( 3 ), faces the contact carrier plate ( 4 ) on which the core ( 1 ) is attached by means of the adhesive surface ( 5 ). is glued on the sides to a distance ( 6 ) that the wires of the winding ( 3 ) can be accommodated there.

In üblicher Weise werden die Wicklungsenden automatisch an die Vorsprünge der Kontaktträgerplatten (4) angewickelt. Die Verlötung erfolgt dann vorzugsweise während des SMD-Montageprozesses.In the usual way, the winding ends are automatically wound on the projections of the contact carrier plates ( 4 ). The soldering then preferably takes place during the SMD assembly process.

Die der Klebefläche (5) gegenüberliegende Fläche (7) in Abb. 2 dient zur Montage mittels Vakuumpinzette.The surface ( 7 ) in Fig. 2 opposite the adhesive surface ( 5 ) is used for assembly using vacuum tweezers.

Claims (2)

1. Hochfrequenzübertrager für SMD-Montage, der auf einer Kontaktträgerplatte montiert ist und die erforderlichen Wicklungen auf einem Kern trägt, dadurch gekennzeichnet, daß der Kern (21) derart ausgestaltet ist, daß zwischen der Kontaktträgerplatte (4) und dem Kern (1) außerhalb der Klebefläche (5) Abstände (6) gebildet sind, die auch an dieser Stelle Wicklungen unterzubringen erlaubt.1. High-frequency transmitter for SMD assembly, which is mounted on a contact carrier plate and carries the required windings on a core, characterized in that the core ( 21 ) is designed such that between the contact carrier plate ( 4 ) and the core ( 1 ) outside the adhesive surface ( 5 ) spaces ( 6 ) are formed, which also allows windings to be accommodated at this point. 2. Hochfrequenzübertrager nach Anspruch 1, dadurch gekennzeichnet, daß die der Klebefläche (5) gegenüberliegende Fläche (7) zur Montage mittels Vakuumpinzette dient.2. High-frequency transmitter according to claim 1, characterized in that the adhesive surface ( 5 ) opposite surface ( 7 ) is used for assembly by means of vacuum tweezers.
