Sämtliche, vorstehend erläuterte HF-Drosseln in Chip-Bauweise sind nur mit verhältnismäßig großem konstruktiven und fertigungstechnischen Aufwand herstellbar.All of the above-explained RF chokes in chip design are only with relatively large constructive and manufacturing effort can be produced.
Der vorliegenden Neuerung liegt die Aufgabe zugrunde, eine elektrische Drossel zu schaffen, welche unter Ausschluß der vorerwähnten Nachteile dieser speziellen HF-Drosseln die zweifelsfrei vorhandenen Vorteile der Chip-Bauelemente, insbesondere auch ihre zuverlässige Bestückung bei kleinen Abmessungen mit den Vorteilen der bekannten axial bedrahteten HF-Drosseln, insbesondere deren gute elektrische und magnetische Eigenschaften vor allem bei hohen Resonanzfrequenzen vereinigt.The present innovation is based on the task of creating an electrical throttle which is excluded the aforementioned disadvantages of these special HF chokes the undoubted advantages of the chip components, especially their reliable assembly with small dimensions with the advantages of known axially wired HF chokes, in particular their good electrical and magnetic properties united especially at high resonance frequencies.
Zur Lösung dieser Aufgabe sieht die Neuerung bei einer elektrischen Drossel der eingangs genannten Art vor, daß die Anschlußdrähte gekrümmt und ihre freien Enden im rechten Winkel zur Drossellängsachse ausgebildet sind, derart, daß die auf die Leiterplatte aufgelötete Drossel sich auf diese Enden abstützt.To solve this problem, the innovation in an electrical throttle of the type mentioned provides that the connecting wires are curved and their free ends are formed at right angles to the longitudinal axis of the throttle, such that the throttle soldered onto the printed circuit board is supported on these ends.
Die Neuerung wird nachstehend anhand eines Ausführungsbeispieles näher erläutert. Es zeigt: The innovation is explained in more detail below using an exemplary embodiment. It shows:
Fig. 1 eine HF-Drossel gemäß der Neuerung in perspektivischer Darstellung1 shows an HF choke according to the innovation in a perspective view
Fig. 2 eine teils geschnittene und gebrochene Ansicht der HF-Drossel nach Fig. 1.FIG. 2 shows a partially sectioned and broken view of the HF choke according to FIG. 1.
Die in Fig. 1 und und 2 dargestellte HF-Drossel 1 besitzt einen mit Gießharz 4 umpreßten Ferrit-Rollenkern 5, 6, dessen verjüngter Teil 6 als Träger einer Wicklung 8 dient. Die Stirnseiten 5 des Ferrit-Rollenkern sind mit Sachlächern 7 ausgebildet, in denen AnschlußdrähteThe HF choke 1 shown in Fig. 1 and and 2 has a ferrite roller core 5, 6, which is pressed around with casting resin 4. the tapered part 6 of which serves as a support for a winding 8. The end faces 5 of the ferrite core are formed with Sachlächern 7, in which connecting wires

verankert sind. In ihren mit Gießharz umpreßten Bereichen sind die Anschlußdrähte 2 mit den Enden 9 bzw, 10 der Wicklung 8 kontaktiert.are anchored. The connecting wires 2 are in contact with the ends 9 and 10 of the winding 8 in their areas encapsulated with casting resin.
Gemäß Fig. 1 sind die Anschlußdrähte 2 gekrümmt und ihre freien Enden 3 im rechten Winkel zur Drossellängsachse . ausgebildet, derart, daß die auf die in der Zeichnung nicht dargestellte Leiterplatte aufgelötete Drossel 1 sich auf diese Enden 3 abstützt. Die Krümmung der Anschlußdrähte kann beliebig gewählt werden, z.B. horn- oder kufenförmig.According to FIG. 1, the connecting wires 2 are curved and their free ends 3 are at right angles to the longitudinal axis of the throttle . designed in such a way that the throttle 1 which is soldered onto the printed circuit board (not shown in the drawing) is supported on these ends 3. The curvature of the connecting wires can be chosen arbitrarily, e.g. horn- or runner-shaped.
Gleiches gilt für die freien Ende, die z.B. - wie in Fig. 1 dargestellt ist - flachgedrückt sind.The same applies to the free ends, which for example - as shown in Fig. 1 - are flattened.
Das gezeigt Bauelement vereinigt in sich sämtliche erwähnten Vorteile der axial bedrahteten HF-Drosseln mit den Vorteilen der Chip-Bauelemente, wobei zur Umformung der axial bedrahteten Bauelemente in chipgerechte zusätzlich nur ein Biegeverfahren, gegebenenfalls kombiniert mit einem Abplatten der freien Enden der Anschlußdrähte erforderlich ist.The component shown combines all the mentioned advantages of the axially wired RF chokes the advantages of the chip components, in addition to the reshaping of the axially wired components into chip-compatible ones only one bending process, possibly combined with a flattening of the free ends of the connecting wires is required.
