Description
Verfahren zur Herstellung von veränderbaren Platten-, insbesondere Drehkondensatoren, bei dem die feststehenden und beweglichen Platten gemeinsam geschichtet werden Die Erfindung betrifft ein Verfahren zur Herstellung von veränderbaren Platten-, insbesondere Drehkondensatoren. Blei dem bekannten Verfahren werden meist die Blechpakete des beweglichen Teils für sich und die Blechpakete des feststehenden Teils für sich hergestellt und dann beide Pakete zusammengebaut. Hierbei ist es außerordentlich schwierig, mit Sicherheit die geforderte und der Berechnung zugrunde liegende Kapazität zu erhalten. Die unvermeidlichen Abweichungen der Plattendicken von dem der Berechnung zugrunde gelegten Wert bringen, unvorhergesehene Abweichungen des Plattenabstandes und damit der Kapazität mit sich.Process for the production of changeable panels, in particular Rotary capacitors in which the fixed and moving plates are layered together The invention relates to a method for the production of changeable panels, especially variable capacitors. The sheet metal stacks are usually the result of the known process the moving part for itself and the laminated cores of the fixed part for itself made and then both packages assembled. Here it is extraordinary difficult, with certainty the required capacity and on which the calculation is based to obtain. The inevitable deviations of the panel thickness from that of the calculation bring the underlying value, unforeseen deviations in the distance between the plates and thus the capacity with it.
Man hat bereits vorgeschlagen, die feststehenden und die 'beweglichen Platten des Kondensators gemeinsam unter Zwischenlage von Abstandshaltern zu schichten und dann in dieser Lage auf ihren Befestigungsteilen festzuhalten. Hierdurch wird ;erreicht, daß bei Verwendung vollkommen gleich dicker Abstandsplatten unabhängig von der Dicke der einzelnen Kondensatorplatten überall gleicher Abstand zwischen einer feststehenden und der benachbarten beweglichen Platte und dadurch mit Sicherheit der gewünschte Kapazitätswert des Kondensators erhalten wird.It has already been suggested that the fixed and the 'movable' Layer the plates of the capacitor together with spacers in between and then to hold onto their fasteners in this position. This will ; achieves that regardless of the use of spacer plates of the same thickness of the thickness of the individual capacitor plates, the same distance between a fixed and the adjacent movable plate and therefore with certainty the desired capacitance value of the capacitor is obtained.
Da die feststehenden Platten und die beweglichen Platten jedoch nicht die gleiche äußere Form haben, erhält man nicht überall eine volle Abstützung der Abstandsplatten, so daß beim Schichten der Kondensatorplatten oder beim Befestigen auf ihren Befestigungsteilen die Platten sich an denjenigen Stellen, -an denen die Formen der 6eiden Plattenarten sich nicht überdecken, leicht verbiegen können. Um dies zu vermeiden, sind gemäß der Erfmdung die feststehenden und beweglichen Platten zunächst so ausgebildet, daß sie ungefähr gleiche äußere Form besitzen. Nach der Befestigung der feststellenden und der beweglichen Platten auf ihren Befestigungsteilen werden dann die über die betriebsmäßige Form der Platten überstehenden Teile der Platten weggenommen. Man kann beim Stanzen der Kondensator. platten bereits Einschnitte in die Platten mit einstanzen, die das Wegnehmen der üb@erstehenden Teile nach dem Zusammenbau erleichtern.However, as the fixed plates and the movable plates do not have the same external shape, full support of the Spacer plates so that when layering the capacitor plates or when attaching them on their fastening parts, the plates are in those places where the Shapes of the two types of panels do not overlap and can easily bend. Around To avoid this, the fixed and movable plates are according to the invention initially designed so that they have approximately the same external shape. After Fixing the locking and moving plates on their mounting parts are then the parts of the projecting over the operational shape of the plates Plates taken away. One can when punching the capacitor. already plate incisions punch into the plates, which means that the remaining parts can be removed after the Facilitate assembly.
Mit diesem Herstellungsverfahren kann man auch dann richtige Kapazitätswerte verhalten, wenn die Abstandsplatten nicht vollkommen gleich dick sind. Es läßt sich mathematisch nachweisen, daß es genügt, wenn die Summe aller Plattenabstände eines Kondensators gleich der Summe der für die Erreichung einer bestimmten Kapazität errechneten Einzelabstände ist. Es genügt also vollkommen, wenn gemäß einer weiteren vorteilhaften Ausgestaltung des Verfahrens nach der Erfindung die Abstandsplatten für einen Kondensator so ausgewählt werden, daß die Dicke oder das Gewicht sämtlicher Abstandsplatten eines Kondensators zusammengenommen so groß ist wie die errechnete Gesa:mtdieke oder das errechnete Gesamtgewicht sämtlicher Abstandsplattem.With this manufacturing process you can also get correct capacitance values behave if the spacer plates are not exactly the same thickness. It can be prove mathematically that it is sufficient if the sum of all plate distances is one Capacitor equal to the sum of the necessary to achieve a certain capacity calculated individual distances. So it is completely sufficient if, according to another advantageous embodiment of the method according to the invention, the spacer plates for a capacitor be selected so that the thickness or the The combined weight of all the spacer plates of a capacitor is so great like the calculated total: mtdieke or the calculated total weight of all spacer plates.
