TransduktorTransducer
Die Erfindung betrifft einen Transduktor, dessen Magnetkreis aus einem Kern und einem Joch besteht.The invention relates to a transducer whose magnetic circuit is made of consists of a core and a yoke.
Insbesondere in der Fernsehtechnik werden Transduktoren als veränderbare Induktivitäten beispielsweise in den Ablenkkreisen von Fernsehempfängern verwendet.In television technology in particular, transducers are used as changeable Inductances, for example, in the deflection circuits of television receivers used.
Bei solchen Transduktoren sind auf einem mehrsohenkligen Kern Arbeitsund Steuerwicklungen angeordnet. Die Induktivität der Wicklungen wird u.a. wesentlich durch den Luftspalt bestimmt, der sich an der Stossstelle zwischen den einzelnen Kernschenkeln und dem die Schenkel verbindenden Joch befindet.With such transducers there is a multi-faceted core of work Arranged control windings. The inductivity of the windings is largely determined by the air gap at the joint is located between the individual core legs and the yoke connecting the legs.
In den Luftspalt soloher Transduktoren wird in bekannter Weise eine sogenannte Luftspalteinlage eingebracht, die üblicherweise eine Dicke von 5 bis 20/Um hat.In the air gap of solo transducers, a so-called Introduced air gap insert, which usually has a thickness of 5 to 20 / um.
Da es sich bei Transduktoren für den obigen beispielsweisen Anwendungsfall um ein Produkt handelt, das in Massenfertigung hergestellt wird, ist es leicht einzusehen, dass das Einbringen einer Folie von der angegebenen Stärke von z.B. 5 ,van erhebliche Schwierigkeiten bereitet und folglich die Herstellungskosten ungünstig beeinflusst. Eine weitere Schwierigkeit tritt dann auf, wenn der Kern und das Joch unter Einschluss der Luftspalteinlage in der üblichen Weise durch Kleben miteinander verbunden werden. Das hat seine Ursache in den Werkstoffeigenschaften der verwendeten Klebemittel, da die Klebstoffzwischenlage, bedingt durch Klebstoffbeschaffenheit, Aushärtezeit und Aushärtetemperatur, Fertigungsstreuungen unterliegt.Since the transducers for the above exemplary application are a product that is mass-produced, it is easy to see that the introduction of a film of the specified thickness of, for example, 5 van causes considerable difficulties and consequently has an unfavorable effect on the production costs. A further difficulty arises when the core and the yoke, including the air gap insert, are connected to one another in the usual way by gluing. This is due to the material properties of the adhesive used, since the adhesive intermediate layer is subject to manufacturing variations due to the nature of the adhesive, the curing time and the curing temperature.

Eine vorteilhafte Ausgestaltung sieht vor, dass die Luftspalteinlage aus einem ferritbeschiehteten oder ferritgefüllten Kunststoffband besteht. Ein solches Band kann, bei entsprechender Beschichtung oder Pül« lung so stark gewählt werden, dass es leicht zu verarbeiten ist. Wenn der Kern und das Joch durch Kleben miteinander verbunden werden, ist es vorteilhaft, wenn dem Klebstoff ein Füllstoff beigemischt ist, dessen Körnung so gewählt ist, dass der Korndurchmesser dem vorgegebenen Abstand zwischen Kern und Joch entspricht. Bei dieser Ausgestaltung ist bei der Herstellung nur darauf zu achten, dass durch entsprechenden Anpressdruck der vorgegebene Abstand erreicht wird, woduroh keine besondere Sorgfalt beim Auftragen des Klebstoff-Füllstoff-Gemisches erforderlich ist.An advantageous embodiment provides that the air gap insert consists of a ferrite-coated or ferrite-filled plastic tape. Such a tape can, with the appropriate coating or wash, should be chosen so strong that it is easy to work with. When the core and the yoke are joined together by gluing, it is It is advantageous if a filler is added to the adhesive, the grain size of which is selected so that the grain diameter corresponds to the specified Corresponds to the distance between the core and the yoke. With this configuration, it is only necessary to ensure that by appropriate Contact pressure the specified distance is achieved, where no special Care must be taken when applying the adhesive-filler mixture is.

Gemäss Fig. 1 besteht der Transduktor aus einem Kern 11, den auf die Schenkel verteilten Wicklungen 15, 16 und 17, dem Joch 14, der Montageplatte l8 und der Luftspalteinlage 12 und 13. Der Luftspalt ist hier der Deutlichkeit wegen vergrössert dargestellt.According to Fig. 1, the transducer consists of a core 11, which is on the Legs distributed windings 15, 16 and 17, the yoke 14, the mounting plate l8 and the air gap insert 12 and 13. The air gap is here shown enlarged for the sake of clarity.
Bei dem hier gezeigten Ausführungsbeispiel handelt es sich um einen Transduktor, bei dem die Luftspalteinlage 13 ein ferritbeschichtetes oder ferritgefülltes Kunststoffband ist. Die beiden Schichten 12 können zusätzliche Klebstoffschichten sein, wenn keine anderen mechanischen Verbindungselemente vorgesehen sind. Der mechanische Zusammenhalt von Kern und Joch kann aber auch z.B. durch eine aussen umgelegte Klammer oder dergleichen erreicht werden. Der vorgegebene Wert des magnetischen Widerstandes des Luftspaltes kann je nach Dicke der Luftspalteinlage 13 bzw. 12 und 13 durch entsprechende Anreicherung der Ferritbesehichtung oder Ferritfüllung erreicht und eingehalten werden.The embodiment shown here is one Transductor in which the air gap insert 13 is a ferrite-coated or ferrite-filled plastic tape. The two layers 12 can be additional layers of adhesive, if not other mechanical ones Connecting elements are provided. The mechanical cohesion of the core and yoke can also be achieved, for example, by an externally folded Bracket or the like can be achieved. The specified value of the magnetic resistance of the air gap can vary depending on the thickness of the air gap insert 13 or 12 and 13 by enriching the Ferrite coating or ferrite filling are achieved and adhered to.
In Fig. 2 ist ausschnittsweise ein Transduktor gezeigt, bei dem der Kern 11 und das Joch 14 aufeinander geklebt sind. In den Klebstoff 12 ist ein Füllstoff 19 eingebettet. Der Abstand zwischen Kern 11 und Joch l4 ist, wie aus der Darstellung deutlich hervorgeht, durch den Korndurchmesser des Füllstoffes 19 bestimmt. Auch hier sind der Luftspalt und dessen Füllung übertrieben gross dargestellt.In Fig. 2, a section of a transducer is shown in which the Core 11 and the yoke 14 are glued to one another. A filler 19 is embedded in the adhesive 12. The distance between core 11 and Yoke 14 is, as can be clearly seen from the illustration, by the Grain diameter of the filler 19 is determined. Here, too, are the air gap and its filling is exaggerated.
Der Füllstoff 19 kann je nach Wahl dia-, para- oder ferromagnetischer Art sein. Es ist bei dieser Ausführung auf eine gleichmässige Körnung des Füllstoffes 19 zu achten.The filler 19 can be dia-, para- or ferromagnetic, depending on the choice Be kind. In this design, it is important to have a uniform grain size of the filler 19 must be observed.
