Description

Verfahren zur Herstellung von Schutzüberzügen durch Tauchen auf elektrischen Kondensatoren Die Erfindung betrifft ein Verfahren zur Herstellung von Schutzüberzügen durch Tauchen auf elektrischen Kondensatoren mit axial liegenden Anschlußdrähten oder anderen ebenso aufgebauten elektrischen Bauelementen.Process for the production of protective coatings by dipping on electrical Capacitors The invention relates to a method for producing protective coatings by diving on electrical capacitors with axially lying connecting wires or other similarly constructed electrical components.

Bei einem bekannten Tauchverfahren erfolgt das Tauchen in axialer Richtung des Bauelements, und zwar derart, daß die Anschlußdrähte zwangläufig mit in die Tauchmasse gelangen, so daß der durch das Tauchen auf den Anschlußdrähten entstandene überzug in einem gesonderten und unerwünschten Arbeitsgang wieder entfernt werden muß.In a known immersion process, the immersion takes place in an axial direction Direction of the component, in such a way that the connecting wires inevitably with get into the immersion compound, so that the immersion on the connecting wires The resulting coating is removed again in a separate and undesired operation must become.

Ein weiterer Nachteil der bekannten Tauchverfahren besteht in der Gefahr der Bildung von Tropfen oder Verdickungen an dem Tauchmasseüberzug. Durch Wahl geringer Viskosität der überzugsmasse und langsamer Austauchgeschwindigkeit läßt sich diese Gefahr in gewissen Grenzen vermeiden. Andererseits ist es jedoch besonders bei Kondensatoren erwünscht, durch größere Viskosität dickere Überzüge zu erhalten und schnellere Tauchgeschwindigkeiten anwenden zu können. Es ist zwar auch schon bekannt, eine Tropfenbildung durch Drehen und Schwenken des Bauelements nach dem Tauchen zu vermeiden, doch läßt sich auch dadurch ein überziehen von axial liegenden Anschlußdrähten mit Tauchmasse nicht verhindern.Another disadvantage of the known dipping process is that Risk of the formation of drops or thickening on the dipping compound coating. By Choice of low viscosity of the coating compound and slow exchange speed this danger can be avoided within certain limits. On the other hand, however, it is Particularly desirable for capacitors, thicker coatings due to higher viscosity and to be able to use faster diving speeds. It is true also already known, a drop formation by rotating and pivoting the component should be avoided after diving, but it can also be used to pull over axially Do not prevent lying connection wires with immersion compound.

Die Erfindung vermeidet die Nachteile der bekannten Tauchverfahren, und zwar dadurch, daß die Bauelemente in waagerechter Lage ihrer durch die An schlußdrähte gehenden Mittelachse vorzugsweise bis zur Hälfte in das Tauchbad eingetaucht und um die Mittelachse gedreht werden, wobei die Anschlußdrähte außerhalb des Tauchmassebades gehalten werden, und ein Antriebselement durch Reibung jeweils auf mindestens einen Anschhißdraht zur Einwirkung gebracht wird.The invention avoids the disadvantages of the known immersion methods, namely by the fact that the components in the horizontal position of their connecting wires through the to going central axis is preferably half immersed in the immersion bath and be rotated around the central axis, with the connecting wires outside of the immersion bath are held, and a drive element by friction on at least one Connection wire is brought into action.

In der Zeichnung ist das erfindungsgemäße Verfahren schematisch wiedergegeben. Dargestellt ist als Ausführungsbeispiel als zu überziehendes Bauelement ein elektrischer Kondensator a mit den beiden axialen Anschlußdrähten b. Das Bauelement a befindet sich in einem Tauchmassegefäß c, das mit der überzugsmasse d gefüllt ist. Die Anschlußdrähte b befinden sich außerhalb des Tauchbades d. Mindestens auf einer Seite der Anschlußdrähte b befinden sich die Antriebselemente e, von denen mindestens ein Antriebselement sich quer zu dem Anschlußdraht b in der Weise bewegt, daß infolge Reibung der Anschlußdraht b und damit das Bauelement a in eine drehende Bewegung versetzt wird.The method according to the invention is shown schematically in the drawing. An electrical capacitor a with the two axial connecting wires b is shown as an exemplary embodiment as the component to be coated. The component a is located in a dipping compound vessel c which is filled with the coating compound d. The connecting wires b are located outside of the immersion bath d. At least on one side of the connecting wires b are the drive elements e, of which at least one drive element moves transversely to the connecting wire b in such a way that the connecting wire b and thus the component a is set in a rotating motion due to friction.
