Description

Drehkondensator mit Platten aus Spritzguß.-Gegenstand der Erfindung ist ein Drehkondensator mit Platten aus Spritzguß. Alle bisher bekannten Ausführungsformen weisen den Nachteil auf, daß heini Zusammenfügen der einzelnen Platten zu einem starr-en Ganzen infolge des Metallspritzgußverfahrens starke Erwärmungen der Platten auftreten. Diese begünstigen ein Werfen der Platten und führen zu ungleichmäßigen Abständen oder sogar Kurzschlüssen. Dieser übelstand wird gemäß der Erfindung dadurch beseitigt, daß die Platten an Stelle der Verbindung durch #pritzgußmetall mit Hilfe eines Isoliermaterials zu einem starren Gebilde verbunden werden. Dieses Herstellungsverfahren ist wirtschaftlicher als die bisher bekannten und vermeidet vor allem die obenerwähnten Nachteile des Metallspritzgußverfahrens, da es infolge Verwendung von Isoliermaterial bei wesentlich niedrigerer Temperatur erfolgt. Die leitende Verbindung unter den einzelnen Platten des beweglichen und unbeweglichen Sy- stems wird durch Stangen, Drahtverbindungen o. dgl. hergestellt.Rotary capacitor with injection-molded plates. The invention relates to a rotary capacitor with injection-molded plates. All previously known embodiments have the disadvantage that if the individual plates are joined together to form a rigid whole, considerable heating of the plates occurs as a result of the metal injection molding process. These encourage the plates to be thrown and lead to uneven distances or even short circuits. This disadvantage is eliminated according to the invention in that the plates are connected to a rigid structure with the aid of an insulating material instead of being connected by injection-molded metal. This manufacturing process is more economical than the previously known and above all avoids the disadvantages of the metal injection molding process mentioned above, since it takes place at a significantly lower temperature as a result of the use of insulating material. The conductive connection between the individual plates of the movable and immovable sy stems is o by rods wire compounds. Like. Prepared.
