Description

Schwingkontaktstro.mrichter zur Umformung von Gleichstrom in Wechselstrom- ün:d urngeliehrt oder .auch zur Umformung von Wechselstrom in solchen anderer Frequenz benutzen federnd angeordnete feste Gegenkontakte; die beim Kontaktschluß von ihrenGegenlagen ,abgehoben werden und die ibei Öffnung der Kontakte gegen ihre Gegenlagen -schlagen und daibei mit ihrer etwa vier- bis achtmal die Stromrichterfrequenz übertreffenden Eigenfrequenz: anschwingen. Dieses Ansd'.hwingen muß für preäfreie Kontaktbetätigung -bereits zur Ruhe gekommen sein, wenn. der Sehwinglwntakt für die nächste Kontaktbetätigung zurückkehrt.Vibrating contact converter for converting direct current into alternating current ün: d urned or .also for converting alternating current in such a different frequency use resiliently arranged fixed mating contacts; those at the time of making contact with their counterparts , are lifted and hit the ibei opening of the contacts against their counterparts and with its about four to eight times the converter frequency Natural frequency: start to oscillate. This Ansd'.hwingen must for pre-free contact actuation -Already have come to rest when. the visual oscillation cycle for the next contact activation returns.

Erfindungsgemäß werden die Gegenkontaktfedern .auf ihrer freien Oberfläche, namentlich auf ihrer Außenseite, mit einem nichteintrocknenden, zähflüssig bleibenden organischen Überzug, z. B. einer Kohlenwasserstoffverbindung mit ;großer innerer Reibung und vorzugsweise poröser Struktur, wie Schwammgummi und vorzugsweise Polyisobutylen oder auch einem sogenännten Klebeharz, versehen. Es hat sich gezeigt, daß derartig behandelte Gegenkontaktfedern noch nach vielen tausend Stunden eine hinreichende Dämpfung zeigen, was auch dadurch in Erscheinung tritt,-daß zusätzlich eine erhebliche Geräuschdämpfung erzielt wird.' ' Die Figur zeit einen Schwingkontäktstromrichter nach ider Erfindung, der in an sich bekannter Weise mit Schwingkontaktfe-der i, Erregeranker a, Erregerpol q:, Erregerkontakt 5 und fest angeordneten Gegenkontaktfedern 6 -mit Gegenlagen ? für diese Gegenkontaktfedern versehen ist. Die Federn 6 werden von der Schwingkontaktfeder i bei Kontaktschluß .abgehoben und schlagen bei Öffnung der . Kontakte !gegen die oberen Enden der Gegenlagen, wobei sie mit ihrer höhen Eiggenfrequenz um diese schwingen. Erfindungsgemäß ist die freie Oberfläche,der Gegenlkontaktfe.dern 6, namentlich außen, wie dargestellt, mit einem dünnen, mechanisch stark dämpfenden Überzug 8 aus einem organischen Stoff überzogen.According to the invention, the mating contact springs are .on their free surface, namely on their outside, with a non-drying, viscous one organic coating, e.g. B. a hydrocarbon compound with; large inner Friction and preferably porous structure, such as sponge rubber and preferably polyisobutylene or a so-called adhesive resin. It has been shown that such treated mating contact springs still suffice after many thousands of hours Show attenuation, which also appears as a result, -that additionally a considerable Noise attenuation is achieved. ' 'The figure shows a swing contact converter according to the invention, which in a known manner with oscillating contact spring i, Exciter anchor a, exciter pole q :, exciter contact 5 and fixed mating contact springs 6 -with counter supports? is provided for these mating contact springs. The springs 6 are lifted off the oscillating contact spring i when the contact is closed and hit when it opens the . Contacts! Against the upper ends of the counter supports, with their heights Eigenfrequency to oscillate around this. According to the invention, the free surface is the Gegenlkontaktfe.dern 6, namely outside, as shown, with a thin, mechanical strong damping cover 8 made of an organic material.
