Description
Kondensator für Hochfrequenz- und Rundfunkzwecke Die Erfindung betrifft Kondensatoren verhältnismäßig großer Kapazität bei beschränkten räumlichen Abmessungen für Hochfrequenz- und Rundfunkzwecke mit einem Dielektrikum aus verlustarmem keramischem Isolierstoff hoher Dielektrizitätskonstante, wie dieser beispielsweise unter den als Warenzeichen geschützten Namen »Condensa« oder »Condensa C« bekannt ist.Capacitor for radio frequency and broadcast purposes The invention relates to Capacitors of relatively large capacitance with limited spatial dimensions for high frequency and broadcasting purposes with a dielectric made of low-loss ceramic Insulating material with a high dielectric constant, such as this one, for example, under the as a trademark protected name »Condensa« or »Condensa C« is known.
Gemäß der Erfindung ist der aus den genannten Materialien gefertigte Kondensatorkörper. in Form eines leitend belegten ein-oder mehrgängigen Spiralrippenkörpers gehalten.According to the invention is made of the materials mentioned Capacitor body. in the form of a conductive, single or multiple spiral rib body held.
Fig. i stellt zur Hälfte in Ansicht und zur Hälfte im Mittelschnitt eine Ausführungsform des erfindungsgemäßen Kondensators dar.Fig. I represents half in view and half in central section represents an embodiment of the capacitor according to the invention.
Aus einem keramischen Zylinder io verhältnismäßig großer Wandstärke ist ein fortlaufender Spiralengang großer Tiefe herausgedreht. Die Spiralrippen i i werden allseitig mit z. B. aufgeschmelztem Edelmetallbelag 12 und 13 belegt. Hierauf werden die Spitzen der Spiralrippen samt dem darauf befindlichen leitenden Belag weggeschliffen. Auch der Grund der Spiralrippen wird durch Abschleifen von leitendem Belag befreit. Auf diese Weise entstehen 'zwei spiralförmig verlaufende, voneinander durch die abgeschliffenen, belagfreien Strecken isolierte Belegungen 12 und 13, von denen die eine, 13, über die untere Stirnfläche des Kondensatorkörpers io bis zu der in dessen Bohrung eingelöteten Metallkappe 1.4 mit dem Anschluß 15 und die andere Belegung 12 bis zu der an dem oberen Ende des Kondensatorkörpers io eingelöteten Metallkappe 16 mit dem Anschluß 17 geführt ist.From a ceramic cylinder io relatively large wall thickness a continuous spiral duct of great depth is turned out. The spiral ribs i i are marked on all sides with z. B. fused precious metal coating 12 and 13 occupied. Thereupon the tips of the spiral ribs together with the conductive one located on them Surface sanded away. The bottom of the spiral ribs is also made by grinding conductive covering freed. In this way 'two spiraling, Assignments isolated from each other by the sanded, uncovered stretches 12 and 13, one of which, 13, over the lower face of the capacitor body io up to the metal cap 1.4 soldered in its bore with the connection 15 and the other occupancy 12 up to that on the upper end of the capacitor body io soldered metal cap 16 is guided to the terminal 17.
Infolge der großen Länge der sich auf diese Weise ergebenden Kondensatorbelegungen kann deren Ohmscher Widerstand unter Umständen unzulässig groß werden, so daß es zweckmäßig erscheint, die leitend belegten Spiralrippen mehrgängig anzuordnen und Belegungen gleicher Polarität nebeneinanderzuschalten. Ein Ausführungsbeispiel der neuartigen Kondensatoren, die dies ermöglichen, ist in der Fig.2 dargestellt.As a result of the great length of the capacitor assignments that result in this way their ohmic resistance may be impermissibly large, so that it It appears expedient to arrange the conductively coated spiral ribs in multiple threads and Assignments of the same polarity to be switched next to one another. An embodiment of the novel capacitors that make this possible is shown in Fig.2.
Auf den Kondensatorkörper 28 sind mehrgängige Spiralrippen 29 bis 32 mit aufgeschmelzten Belagbändern vorgesehen, die durch metallische, auf die Enden des Kondensatorkörpers aufgelötete Metallkappen ihrerPolarität entsprechend parallel geschaltet werden. Die Ausführung des Kondensators entspricht dabei im übrigen dem in Fig. i wiedergegebenen Beispiel. ,On the capacitor body 28 are multi-turn spiral ribs 29 to 32 is provided with fused covering strips that are attached to the ends by metal The metal caps soldered onto the capacitor body are parallel according to their polarity be switched. The design of the capacitor corresponds to the rest of the Example shown in Fig. i. ,
