Description

Verfahren zur Herstellung von gelöteten Drehkondensatoren Die Erfindung bezieht sich auf ein Herstellungsverfahren für gelötete Drehkondensatoren. Solche Kondensatoren wurden big dahin ,aus Messing oder aus einem Werkstoff angefertigt, der lötbar ist. War der Werkstoff selbst nicht lötbar, so wurde er mit einem Metallüberzug versehen, der .nunmehr das Löten gestattete. Aus bekannten Gründen isst jedoch die Verwendung von Messing, Kupfer, Nickel u. dgl. für die Herstellung von Drehkondensatoren unerwünscht.Method of Making Soldered Rotary Capacitors The invention relates to a manufacturing process for soldered variable capacitors. Such Capacitors went big, made of brass or a material which is solderable. If the material itself was not solderable, it was covered with a metal coating provided, which .now allowed soldering. For known reasons, however, she eats Use of brass, copper, nickel and the like for the production of variable capacitors undesirable.

Die Erfindung betrifft ein Verfahren zur Herstellung von gelöteten Drehkondensatoren, welches dadurch ,gekennzeichnet ist, daß die Platten und ihre Tragkörper aus nicht rostendem, nickelfreiem Stahl bestehen und mit einem geeigneten Lötmittel unmittelbar gelötet werden. Es ist zwar schon bekannt, auch Stahl zur Herstellung von Kondensatorplatten zu benutzen, doch handelt es sich dabei um zu Paketen geschichtete Lamellen, die durch seitliche Schrauben zusammengepreßt werden. Gelötete Stahllamellenp.akete sind dagegen bisher nicht hergestellt worden. Mist dem neuen Verfahren werden nicht nur Kondensatoren erzeugt, deren Temperaturgang wesentlich verbessert ist, sondern !es besteht noch der fertigungstechnische Vorteil, daß alle Vorrichtungen, die für gelötete Drehkondensatoren aus Messing vorhanden sind, ohne Änderung auch für das neue Verfahxen benutzt werden können.The invention relates to a method for producing soldered Rotary capacitors, which is characterized in that the plates and their Carrying body made of stainless, nickel-free steel and with a suitable Solder to be soldered immediately. Although it is already known to use steel as well To use the manufacture of capacitor plates, but it is too Packets of layered lamellas that are pressed together by side screws. On the other hand, soldered steel lamella packets have not yet been manufactured. Damn The new process not only produces capacitors, their temperature response is significantly improved, but! there is still the manufacturing advantage that all devices required for soldered rotary capacitors made of brass are available can also be used for the new procedure without change.

Damit alle Teile des Kondensators den gleichen Temperaturkoeffizienten aufweisen., werden vorteilhaft sämtliche Teile aus der gleichen Stahlsorte angefertigt. Es werden. daher nicht nur der Rotor und der Stator, sondern auch der Mantel mit den. seitlichen. Deckeln aus nicht rostendem, nickelfreiem Stahl. hergestellt. In jedem Falle aber kommet als Werkstoff nur ein solcher Stahl. in Betracht, der nicht vorher verzinnt oder sonstwie durch einen Metallüberzug zum Löten geeignet gemacht werden muß. Auf alle solche Werkstoffe bezieht sich die Erfindung nicht.So that all parts of the capacitor have the same temperature coefficient Have., all parts are advantageously made from the same type of steel. It will. hence not only the rotor and the stator, but also the jacket the. lateral. Lids made of stainless, nickel-free steel. manufactured. In in any case, however, only such steel comes as material. into consideration who does not previously tinned or otherwise through a metal coating for soldering must be made suitable. The invention relates to all such materials not.
