Description
Die Erfindung bezieht sich auf einen elektrischen Kondensator, insbesondere Wickelkondensator, mit Schutzhülle, die durch eine mit Lack überzogene Schicht aus Wachs oder einer anderen plastischen Masse gebildet ist.The invention relates to an electrical capacitor, in particular Winding capacitor, with protective cover made up of a layer coated with varnish Wax or other plastic mass is formed.
Es ist vorgeschlagen worden, die Anschlußdrähte des Kondensators an ihren am Kondensatorwickel befindlichen Enden so zu versteifen und zu verankern, daß ein Verbiegen der Drähte nur außerhalb der Schutzhülle möglich ist. Dadurch wird der bei früher bekannten Kondensatoren vorhandene Übelstand beseitigt, daß die Anschlußdrähte beim Abbiegen die die Schutzhülle bildende plastische Schicht und ihren Lacküberzug aufreißen. Zum Versteifen und Verankern der Anschlußdrahtenden sind nach diesem Vorschlag beispielsweise Kappen, Hülsen od. dgl. vorgesehen, die durch die plastische Schicht und ihren Lacküberzug hindurchragen und zweckmäßig zugleich als elektrische Kontaktkörper zum Verbinden der Anschlußdrähte mit den Metallbelägen des Kondensatorwickels dienen.It has been suggested to connect the leads of the capacitor to it to stiffen and anchor their ends on the capacitor winding in such a way that that a bending of the wires is only possible outside of the protective cover. Through this the drawback existing in previously known capacitors is eliminated that the connecting wires when bending the plastic layer forming the protective cover and tear open their varnish coating. For stiffening and anchoring the connecting wire ends are according to this proposal, for example caps, sleeves or the like. Provided that protrude through the plastic layer and its lacquer coating and expedient at the same time as an electrical contact body for connecting the connecting wires with the Metal coverings of the capacitor winding are used.
Die Erfindung liefert ein besonders einfaches und billiges Mittel zum Versteifen und Verankern der Anschlußdrahtenden am Kondensatorwickel. Erfindungsgemäß sind die in den Kondensatorwickel in bekannter Weise röhrenförmig eingewickelten Anschlußstreifen an ihren äußeren, aus dem Wickel herausragenden Enden um die Anschlußdrähte herumgebördelt oder -gepreßt und von einer aufgeschmolzenen Umhüllung aus Lötzinn od. dgl. dicht umschlossen.The invention provides a particularly simple and inexpensive means for stiffening and anchoring the connection wire ends on the capacitor winding. According to the invention are those wrapped in a known manner in a tubular shape in the capacitor winding Terminal strips at their outer ends protruding from the coil around the connecting wires crimped or pressed around and of a melted coating of tin solder or the like tightly enclosed.
Ein Ausführungsbeispiel eines Wickelkondensators mit den Merkmalen der Erfindung ist in der Zeichnung im Längsschnitt schematisch dargestellt.An embodiment of a wound capacitor with the features the invention is shown schematically in the drawing in longitudinal section.
In den Kondensatorwickel a sind in bekannter Weise die Anschlußstreifen b und c, die z. B. aus Kupferfolie bestehen, röhrenförmig eingewickelt. Die stirnseitig aus dem Kondensatorwickel herausragenden Enden b1, c1 dieser Anschlußstreifen sind um die Enden der Anschlußdrähte d und e herumgebördelt oder herumgepreßt. Zweckmäßig werden diese Streifenenden gleichzeitig mit dem Herumbördeln oder -pressen oder in einem zusätzlichen Arbeitsgang mit den Drahtenden verschweißt. Die die Anschlußdrähte d und e eng umfassenden Enden bi, c1 der Anschlußstreifen b, c sind mit einer aufgeschmolzenen Umhüllung f bzw. g aus Lötzinn od. dgl. versehen, die das betreffende Anschlußstreifenende dicht umschließt und so bemessen ist, daß sie aus der später aufgetragenen, z. B. aus Kunstwachs und einem Lacküberzug hergestellten Schutzhülle la herausragt.In the capacitor winding a, the terminal strips b and c, the z. B. made of copper foil, wrapped in a tubular shape. The ends b1, c1 of these connecting strips protruding at the front from the capacitor winding are crimped or pressed around the ends of the connecting wires d and e. These strip ends are expediently welded to the wire ends at the same time as the crimping or crimping or in an additional operation. The ends bi, c1 of the connecting strips b, c closely encompassing the connecting wires d and e are provided with a fused-on sheathing f or g made of solder or the like, which tightly encloses the relevant connecting strip end and is dimensioned so that it can be removed from the later applied, e.g. B. made of synthetic wax and a varnish coating protrudes protective cover la.
Die Umhüllungen f und g besitzen eine etwa kegelstumpf- oder paraboloidförmige Gestalt und sind am Fuße bis etwa auf den Wickeldurchmesser der Anschlußstreifen verbreitert, was einfach durch Aufschmelzen einer genügend großen Menge Lötzinn od. dgl. erreicht wird.The envelopes f and g have an approximately truncated cone or paraboloid shape Shape and are at the foot to about the winding diameter of the connecting strips widened, which simply by melting a large enough amount of solder or the like. Is achieved.
