Description
Hochfr equenzeisenkernspule. Die Erfindung befasst sich mit einer zweckmässigen Ausbildung einer Hochfre- quenzeisenkernspule, bei der der Hochfre- quenzeisenkern in den Spulenkörper eindreh bar ist. Es sind derartige Ilochfrequenzeisen- spulen bekannt geworden; bei diesen besitzt jedoch sowohl der Spulenkörper als auch der Hochfrequenzeisenkern Gewinde.
Dies hat den Nachteil, dass das Gewinde bei dem Hoch frequenzeisenkern leicht ausbricht, da das Material äusserst spröde ist. Ausserdem muss bei derartigen Kernen demzufolge das Ge winde sehr grosse Steigung haben, da ein Feingewinde in dem spröden Material des Kernes nicht ausführbar ist. Grosse Steigung eines Gewindes bedingt aber, dass eine Fein einstellung schwer möglich ist.
Die Erfindung besteht nun darin, dass lediglich der Spulenkörper mit Gewinde ver sehen und der Eisenkern mit einer deformier baren Einlage versehen ist, die sich in das Gewinde des Spulenkörpers einlegt. Der Vorteil dieser Anordnung besteht darin, dass das Gewinde des Spulenkörpers mit einer kleinen Steigung ausgeführt werden kann, so dass eine Feineinstellung leicht möglich ist, und ausserdem ein Verletzen des Hochfre- quenzeisenkernes durch Ausbrechen eines Ge windes nicht mehr möglich ist.
In den Abb. 1 bis 5 der beiliegen den Zeichnung ist eine beispielsweise Aus führungsform des Erfindungsgegenstandes dargestellt.
Die Abb. 1 bis 3 zeigen einen Hochfre- quenzeisenkern; die Abb. 4 und 5 den Hoch frequenzeisenkern mit einer eingelegten de formierbaren Einlage. In dem Hochfrequenz- eisenkern 1 sind beispielsweise drei Ein schnitte 2 angebracht, in die je eine defor- mierbare weiche Einlage 3, beispielsweise Filz, eingelegt ist. Die Filzeinlagen ,stehen dabei über den Umfang des Eisenkernes hinaus vor und legen sich in die Gewinde gänge des Spdenkörpers ein.
Vorzugsweise ist die deformierbare weiche Einlage, bei spielsweise Filz, in die Einschnitte einge- klebt. Der Eisenkern enthält zweckmässiger weise an einer Endfläche Zapfen 4 oder auch Einschnitte, damit ein Eindrehen des Eisen kernes in den Spulenkörper mittels eines Schlüssels oder Schraubenziehers leicht möb- lich ist.
High frequency iron core coil. The invention is concerned with an expedient design of a high-frequency iron core coil in which the high-frequency iron core can be screwed into the coil body. Such Ilochfrequenzeisen- coils have become known; In these, however, both the coil body and the high-frequency iron core have threads.
This has the disadvantage that the thread of the high-frequency iron core breaks easily because the material is extremely brittle. In addition, in such cores, the thread must accordingly have a very large pitch, since a fine thread cannot be executed in the brittle material of the core. However, a large pitch of a thread means that fine adjustment is difficult.
The invention consists in that only the bobbin see with thread ver and the iron core is provided with a deformier ble insert which is inserted into the thread of the bobbin. The advantage of this arrangement is that the thread of the bobbin can be designed with a small pitch so that fine adjustment is easily possible, and furthermore it is no longer possible to damage the high-frequency iron core by breaking a thread.
In Figs. 1 to 5 of the accompanying drawings, an example from the embodiment of the subject invention is shown.
Figs. 1 to 3 show a high-frequency iron core; Figs. 4 and 5 show the high-frequency iron core with an inserted deformable insert. In the high-frequency iron core 1, for example, three incisions 2 are made, in each of which a deformable soft insert 3, for example felt, is inserted. The felt inlays stand in front of the circumference of the iron core and insert themselves into the threads of the Spden body.
The deformable soft insert, for example felt, is preferably glued into the incisions. The iron core expediently contains pins 4 or also incisions on one end surface, so that it is easy to screw the iron core into the coil body by means of a wrench or screwdriver.
