Description

Verfahren zur Herstellung von einlagigen Hochfrequenzspulen Zur Herstellung von einlagigen Hochfrequenzspulen benutzt man allgemein. einen zylindrischen oder prismatischen vorbereiteten Wickelkörper, auf welchem Einkerbungen oder Rillen zur Aufnahme der einzelnen Windungen vorgesehen sind. Anfang und Ende der Spule wird festgelegt, so daß Veränderungen während des Betriebes nicht auftreten können. Eine derartige Vorbereitung der Wickelkörper ist jedoch nur dann wirtschaftlich, wenn eine sehr große Anzahl gleichartiger Spulen hergestellt werden soll. Werden jedoch viele Spulen benötigt, welche in ihren Abmessungen, Durchmesser, Drahtstärke, Länge und Steigung voneinander abweichen, so ist die serienmäßige Herstellung der Wickelkörper nicht möglich. Die Einzelherstellung erfordert aber großen Aufwand an. Arbeiten und bewirkt eine Verteuerung des Endproduktes.Method for the manufacture of single-layer radio frequency coils For manufacture of single-layer high frequency coils are generally used. a cylindrical or prismatic prepared winding body, on which notches or grooves for Recording of the individual turns are provided. The beginning and end of the bobbin will be so that changes cannot occur during operation. One However, such preparation of the winding body is only economical if a very large number of coils of the same type is to be produced. Will however many coils are required, which in their dimensions, diameter, wire thickness, length and pitch differ from each other, so is the serial production of the winding body not possible. However, the individual production requires great effort. work and causes the end product to become more expensive.

Die Erfindung betrifft eine einlagige Spule für hohe Frequenzen und hohe Spannungen mit starren zylindrischen Windungen, zwischen denen sich Zwischenräume befinden und welche durch isolierende gestreckte Haltestäbe gehalten werden. Bisher wurden die Windungen einer solchen Spule entweder unmittelbar in Einkerbungen in den Stäben gelegt oder mittelbar unter Verwendung von Zwischenstücken aufgewickelt. Diese Zwischenstücke waren teils aus Metall, teils aus Isolierstoff. Bei metallischen Zwischenstücken konnte der Leiter aufgelötet werden. Auch ist es bekannt, die Windungen durch Klebemittel untereinander und mit den Haltestäben zu verbinden. Darüber hinaus sind auch Anordnungen bekanntgeworden, bei denen der Leiter mittels einer Zugverbindung gehalten wird, welche das jeweilige Windungsstück gegen zwei Stäbe preßt. Alle diese Anordnungen genügen jedoch der der Erfindung zugrunde liegenden Aufgabe, nämlich die Schaffung einer einlagigen Spule für hohe Spannungen geringer Kapazität mit Vermeidung von Sprüherscheinungen und hoher mechanischer Festigkeit bei einfachem Aufbau, nicht.The invention relates to a single-layer coil for high frequencies and high voltages with rigid cylindrical windings between which there are spaces are located and which are held by insulating stretched holding rods. Until now the turns of such a coil were either directly in notches in placed on the bars or wound up indirectly using spacers. These spacers were partly made of metal, partly made of insulating material. With metallic The conductor could be soldered onto intermediate pieces. It is also known the coils to be connected to each other and to the holding rods by adhesive. Furthermore arrangements are also known in which the conductor by means of a train connection is held, which presses the respective turn piece against two rods. All these However, arrangements are sufficient for the object on which the invention is based, namely creating a single layer coil for high voltages with low capacitance Avoidance of spray phenomena and high mechanical strength with simple Construction, no.

Bei der Verwendung von Zwischenstücken zwischen den Stäben und dem Spulenleiter wird zwar ein Sprühen an der Auflagefläche des Spulenleiters auf den Zwischenstücken vermieden, wenn diese aus Metall bestehen und der Spulenleiter aufgelötet wird. Lötungen zwischen metallenen Teilen und den Isolierstäben sind jedoch schwierig durchzuführen. Auch die Eigenkapazität der Spule wird durch die Verwendung von metallenen Zwischenlagen oder durch den Befestigungsmechanismus vergrößert.When using spacers between the rods and the Coil conductor is a spray on the contact surface of the coil conductor on the Avoid intermediate pieces if they are made of metal and the coil conductor is soldered on will. However, soldering between metal parts and the insulating rods is difficult perform. The self-capacitance of the coil is also increased through the use of metal Intermediate layers or enlarged by the fastening mechanism.

Es wurde festgestellt, daß die Spannungsfestigkeit der Spule, also das Vermeiden von Sprühungen, wesentlich erhöht und die elektrischen Eigenschaften der Spule durch Verringerung der Eigenkapazität verbessert werden können, wenn der blanke Spulenleiter mittels eines Kitt- oder Klebemittels an die Haltestäbe gelegt wird. Gemäß der Erfindung werden deshalb die Windungen unter vollständiger Ausfüllung,der Hohlräume nahe den Auflagestellen durch ein isolierendes Haftmittel an den Haltestäben allein mittels dieses festgelegt.It was found that the dielectric strength of the coil, so the avoidance of spraying, and significantly increases the electrical properties the coil can be improved by reducing the self-capacitance when the Bare coil conductors are placed on the holding rods using a cement or adhesive will. According to the invention, therefore, the turns are completely filled, the Cavities near the support points by an insulating adhesive on the support rods determined by this alone.

Bei Spulen größeren Durchmessers genügt eine geringe Abrundung der Kanten, um so die Auflageflächen des Spulenleiters auf dem Körper zu vergrößern. Die Spule besitzt einen mit Abstand gewickelten Spulenleiter, der vor dem Festlegen durch ein Kitt- oder Klebemittel mittels beispielsweise kammartiger Lehren ausgerichtet wird. Als Kitt-oder Klebe- und Befestigungsmittel sind polymerisierende oder kondensierende Kunstharze oder Glasfritte geeignet. Besonders zweckmäßig ist die Verwendung von kondensierenden Harzen auf Zellulose-oder Anthoxylinbasis. Eine so hergestellte Spule steht einer auf vorbereitetem und mit Rillen versehenem Wickelkörper aufgebrachten Spule bezüglich seiner mechanischen Festigkeit in keiner Weise nach. Das Festlegen der Windungen auf dem Körper durch ein Kitt- oder Klebemittel verhütet ein Glimmen zwischen der Berührungsstelle des Drahtes und dem Körper, wodurch die Spannungsfestigkeit der Spule gegenüber der bisherigen Bauform wesentlich erhöht wird. Durch das Aufliegen des Spulenleiters auf geringen Auflageflächen des Spulenkörpers können die elektrischen Verluste auch wesentlich kleiner gehalten werden als bei den bekannten Herstellungsarten. Die Herstellungskosten einer nach dem erfindungsgemäßen Verfahren hergestellten Spule liegen wesentlich unter denen nach bisher bekannten Verfahren hergestellten Spulen.For coils of larger diameter, a slight rounding of the is sufficient Edges, so as to enlarge the contact surfaces of the coil conductor on the body. The coil has a spaced-wound coil conductor that is pre-set aligned by a putty or adhesive by means of, for example, comb-like gauges will. Putty or adhesive and fastening means are polymerizing or condensing Synthetic resins or glass frit are suitable. It is particularly useful to use condensing resins based on cellulose or anthoxylin. One made in this way Coil stands on a pre-prepared and grooved bobbin The mechanical strength of the coil does not fall in any way. The setting of the coils on the body by a cement or adhesive prevents smoldering between the point of contact of the wire and the body, increasing the dielectric strength the coil is significantly increased compared to the previous design. By lying down of the coil conductor on small contact surfaces of the bobbin, the electrical Losses can also be kept much smaller than in the known manufacturing methods. The manufacturing costs of a manufactured by the method according to the invention Coils are significantly lower than those produced by previously known methods Wash.

In der Zeichnung ist eine nach dem erfindungsgemäßen Verfahren hergestellte Spule in zwei Ansichten (Fig. i und 2) gezeigt. Der Spulenleiter i liegt an den Kanten zweier parallel montierter Isolierplatten 3 und 4 an. Das Kitt- oder Klebemittel an den Kanten ist mit 5 bezeichnet.In the drawing is one produced by the method according to the invention Coil in two views (Figs. I and 2) shown. The coil conductor i rests on the edges of two insulating plates 3 and 4 mounted in parallel. That Putty or adhesive on the edges is denoted by 5.
