Description

Spule mit keramischem Spulenträger, deren Windungen in Nuten des Spulenkörpers liegen Es sind Spulen bekannt, bei denen der Träger aus Keramik besteht und mit Nuten versehen ist, die die Wicklung aus Metalldraht oder Metallband aufnimmt. Die Unterbringung der Wicklung in Nuten geschieht meist zu dem Zweck, die Wicklung unverschiebbar zu lagern. Bei Spulen, an -die große Konstanzforderungen gestellt werden (z. B. in Steuersendern), genügt in vielen Fällen .diese Festlegung der Wicklung ,nicht. Durch verschiedene Einflüsse, wie Erschütterungen, Temperaturwechsel usw., werden die elektrischen Daten, d. h. sowohl die Induktivität als auch die Eigen- und Raumkapazität der Spule durch geringfügige Verlagerung der Wicklung gegen den Wicklungsträger verändert.Coil with ceramic bobbin, the turns of which are in grooves in the bobbin There are known coils in which the carrier is made of ceramic and with Grooves is provided, which receives the winding of metal wire or metal tape. the The winding is usually placed in slots for the purpose of making the winding immovable to store. For coils that are subject to great constancy requirements (e.g. in exciters), this definition of the winding is not sufficient in many cases. Due to various influences, such as vibrations, temperature changes, etc. the electrical data, d. H. both the inductance and the intrinsic and space capacitance the coil by slightly shifting the winding against the winding support changes.

Erfindungsgemäß wird deshalb vorgeschlagen, .die Wicklung in den Nuten dadurch formstarr festzulegen, daß die Nut metallisiert und die Wicklung nach Einl*gen mittels Lötzinn in die metallisierte Nut eingelötet wird. Es wird dadurch erreicht, daß zwischen Wicklung und Wicklungsträger keine undefinierbaren Verschiebungen auftreten können. Die Abbildung zeigt ein Festlegen der Wicklung durch Anlöten der Wicklungsdrähte an die metallisierte Nut.According to the invention, it is therefore proposed that the winding be in the slots to be rigidly fixed by metallizing the groove and inserting the winding is soldered into the metallized groove using tin solder. It is achieved by that no indefinable displacements occur between the winding and the winding support can. The figure shows a setting of the winding by soldering the winding wires to the metallized groove.
