Elektrisches Bauelement in Chip-Bauweise 5 Die Erfindung betrifft ein elektrisches Bauelement in Chip-Bauweise, insbesondere Ringkerndrossel, das in ein durch einen Deckel verschlossenes Gehäuse eingebaut und rüttel- und schocksicher fixiert ist.Electrical component in chip design 5 The invention relates to an electrical component in chip design, in particular a toroidal core choke, which is installed in a housing closed by a cover and fixed in a vibration- and shock-proof manner.

Ein derartiges Bauelement ist aus dem DE-U 91 11 bekannt. Dort wird eine Ringkernspule beschrieben, die in einem Gehäuse mit einem Mitteldom eingebaut ist, wobei eine Haltescheibe derart angeordnet ist, daß sie oberhalb der Ringkernspule auf dem Mitteldom mittels Preßsitz das Bauelement fixiert.Such a component is known from DE-U 91 11. There, a toroidal core coil is described which is installed in a housing with a central dome, with a retaining disk arranged in such a way that it fixes the component above the toroidal core coil on the central dome by means of a press fit.

Die bekannte Ausführung setzt somit ein Gehäuse voraus, das einen Mitteldom aufweist.The known design therefore requires a housing that has a central dome.

Aufgabe der Erfindung ist es, eine Fixierung für ein elektrisches Bauelement anzugeben, das auch in einfacher und damit preisgünstiger ausgestalteten Gehäusen, insbesondere in Gehäusen ohne Mitteldom, einsetzbar ist.The object of the invention is to provide a fixation for an electrical component which can also be used in simpler and therefore less expensive housings, in particular in housings without a central dome.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zur Fixierung zwischen Deckel und Bauteil ein Zusatzteil angeordnet ist.This object is achieved according to the invention in that an additional part is arranged for fixing between the cover and the component.

Vorteilhafterweise ist das Zusatzteil als Kunststoff-Formteil aus temperaturbeständigem Kunststoff, z. B. SilikonAdvantageously, the additional part is a plastic molded part made of temperature-resistant plastic, e.g. silicone

ausgebildet, und besitzt beispielsweise Kugel- oder Zylinderform bzw. eine Ausbildung als Tellerfeder.designed and has, for example, a spherical or cylindrical shape or a design as a disc spring.

Weiterhin ist es auch möglich, daß das Zusatzteil aus einer plastischen Masse besteht.Furthermore, it is also possible that the additional part consists of a plastic mass.

Die Erfindung wird anhand der folgenden Ausführungsbeispiele näher erläutert.The invention is explained in more detail using the following embodiments.

In der dazugehörenden Zeichnung zeigen,In the accompanying drawing,

FIG 1 eine Fixierung durch ein Kunststoff-Formteil, FIG 2 eine Fixierung durch eine Tellerfeder und FIG 3 eine Fixierung durch eine plastische Masse.FIG 1 shows a fixation by means of a plastic molded part, FIG 2 shows a fixation by means of a disc spring and FIG 3 shows a fixation by means of a plastic mass.

In der FIG 1 ist eine Ringkerndrossel 1 dargestellt, die in einem Gehäuse eingebaut ist, das aus einem becherförmigen Teil 2 und einem Deckel 3 besteht, die an der Stelle 4 beispielsweise durch eine Ultraschall-Schweißung dicht 0 miteinander verbunden sind. Am Boden des becherförmigen Gehäuseteils 2 sind Anschlußdrähte 5 angeordnet.FIG. 1 shows a toroidal core choke 1 which is installed in a housing consisting of a cup-shaped part 2 and a cover 3 which are tightly connected to one another at point 4, for example by ultrasonic welding. Connecting wires 5 are arranged at the bottom of the cup-shaped housing part 2.

Zwischen becherförmigen Gehäuseteil 2 und Deckel 3 ist ein Kunststoff-Formteil 6 angeordnet, das vor dem Einbau z. B. Kugel- oder Zylinderform besitzt und die Ringkerndrossel 1 rüttel- und schocksicher im Gehäuse fixiert.A plastic molded part 6 is arranged between the cup-shaped housing part 2 and the cover 3, which has a spherical or cylindrical shape before installation and fixes the toroidal choke 1 in the housing in a way that is vibration- and shock-proof.

In der FIG 2 ist eine weitere Ausführungsform dargestellt, bei der die Fixierung der Ringkerndrossel 1 durch ein als Tellerfeder 7 ausgebildetes Kunststoff-Formteil erfolgt.FIG 2 shows a further embodiment, in which the toroidal core choke 1 is fixed by a plastic molded part designed as a disc spring 7.

G \ 5 O 5 D€G \ 5 O 5 D€

Die Kunststoff-Formteile 6 bzw. 7 der Figuren 1 und 2 bestehen vorzugsweise aus einem temperaturbeständigem Kunststoff, wie beispielsweise Silikon.The plastic molded parts 6 and 7 of Figures 1 and 2 preferably consist of a temperature-resistant plastic, such as silicone.

In der FIG 3 ist eine weitere Ausführungsform dargestellt, bei der die Fixierung der Ringkerndrossel 1 durch eine plastische Masse 8 erfolgt, die zwischen Deckel und Ringkerndrossel 1 angeordnet ist.FIG 3 shows a further embodiment in which the toroidal core choke 1 is fixed by a plastic mass 8 which is arranged between the cover and the toroidal core choke 1.
