Description
Es ist bekannt. Elektrolyt-Kondensatoren als Mehrfachkapazitäten auszuführen, indem zwei oder mehrere Teilkapazitäten konzentrisch im gleichen Wickel angeordnet werden. Vielfach wird hierbei eine gemeinsame Kathodenfolie als Abgriff für den Minuspol vorgesehen, welche bei der bisher bekannten Bauart die gleiche Breite hat wie die entsprechend der Zahl der gewünschten Teilkapazitäten voneinander getrennt eingeführten positiven Elektroden, die mit der als Dielektrikum wirkenden Oxydschicht bedeckt sind. Für bestimmte Anwendungsfälle solcher Mehrfachkondensatoren können Schwierigkeiten dadurch entstehen, daß die in einem gemeinsamen Wickel befindlichen Teilkapazitäten, die in der Regel an verschiedenen Stellen innerhalb der elektrischen Schaltungsanordnung des Gerätes liegen, nicht ausreichend entkoppelt sind, so daß Wechselspannungen von einer Teilkapazität auf die anderen übertragen werden, die das einwandfreie Arbeiten der Apparatur stören.It is known. Execute electrolytic capacitors as multiple capacities, by arranging two or more partial capacities concentrically in the same winding will. In many cases, a common cathode foil is used as a tap for the Negative pole is provided, which has the same width in the previously known design such as those separated from one another according to the number of partial capacities required introduced positive electrodes with the oxide layer acting as a dielectric are covered. For certain applications such multiple capacitors can Difficulties arise from the fact that they are in a common coil Partial capacities, which are usually in different places within the electrical Circuit arrangement of the device are not sufficiently decoupled, so that AC voltages are transferred from a partial capacity to the other, the disturb the proper functioning of the equipment.
Der Erfindung gemäß lassen sich diese Nachteile vermeiden, wenn folgende Maßnahmen getroffen werden: i. Die als Minuspol des Kondensators dienende Kathodenfolie wird gegenüber den positiven Elektroden verbreitert, so daß diese an beiden seitlichen Rändern von der Kathodenfolie überdeckt «-erden; 2. die positiven Elektroden der zu entkoppelnden Teilkapazitäten werden mit einem gegenseitigen Längsabstand aneinandergelegt, der mindestens einen vollen Wickelumfang beträgt; 3. es ist vorteilhaft, bei mehr als zwei Teilkapazitäten innerhalb des gleichen Kondensators diejenigen Teilkapazitäten möglichst weit voneinander getrennt anzuordnen, bei denen eine Verkopplung in besonderem Maße stören würde. Die vorstehend beschriebenen Maßnahmen können einzeln oder miteinander verbunden angewandt werden.According to the invention, these disadvantages can be avoided if the following Measures are taken: i. The cathode foil serving as the negative pole of the capacitor is widened compared to the positive electrodes, so that they are on both sides Edges covered by the cathode foil «-earth; 2. the positive electrodes of the Partial capacities to be decoupled are placed next to each other with a mutual longitudinal distance, which is at least one full circumference of the winding; 3. It is beneficial for more as two partial capacities within the same capacitor those partial capacities to be arranged as far apart from each other as possible, in which a coupling in particular Dimensions would bother. The measures described above can be carried out individually or together connected.
Eine beispielsweise Veranschaulichung des Erfindungsgedankens ist in der Abbildung schematisch dargestellt, die den Wickel eines Dreifach-Elektrolyt-Kondensators in abgewickeltem Zustand zeigt. Die für alle drei Teilkapazitäten gemeinsame Kathodenfolie 2, die von den positiven Elektroden durch den Abstandhalter i getrennt ist, ist breiter gehalten als die positiven Elektroden 3,4 und 5 der drei Teilkapazitäten, die außerdem bei den zu entkoppelnden Teilkapazitäten voneinander in einem Abstand 6 gehalten werden, der mindestens einem vollen Wickelumfang an dieser Stelle entspricht.An example illustration of the inventive concept is In the figure shown schematically, the winding of a triple electrolytic capacitor shows in the unwound state. The cathode foil common to all three partial capacities 2, which is separated from the positive electrodes by the spacer i held wider than the positive electrodes 3, 4 and 5 of the three partial capacities, in addition, in the case of the partial capacities to be decoupled from each other at a distance 6, which corresponds to at least a full circumference of the winding at this point.
