Description

  

      Hochfrequenzentstördrossel.       Die Erfindung bezieht sich auf     Hochfre-          quenzentstördrosseln,    insbesondere für starke  Ströme, bei denen der     Kraftlinienpfad    in einem  für     Hochfrequenzfelder    geeigneten     ferroma-          gnetischen    Werkstoff verläuft. Bisher wurden  solche Spulen aus Runddraht in mehreren  Lagen über- und nebeneinander gewickelt,  hauptsächlich um die     Windungskapazität     niedrig zu halten. Da Runddraht einen un  günstigen Wicklungsfaktor bat, beanspruchen  solche Spulen viel Raum und sind schwer.

    Die Erfindung vermeidet diesen Nachteil  durch Verwendung von einem bandförmigen  Leiter, der in einer Ebene gewickelt ist. Da  durch wird zwar die     Windungskapazität    etwas  vermehrt, was man jedoch wegen Vermin  derung des Gewichts und wegen Raumer  sparnis bei Fahrzeugen, insbesondere Flug  zeugen, für die der Gegenstand der Erfindung  hauptsächlich bestimmt ist, in Kauf nimmt,  insbesondere da bei gleichem     Spulenquer-          schnitt    bei der     Flachdrahtspule    eine erheb-      lieh grössere     Induktivität    erzielt wird, wie  bei einer     Runddrahtspule.     



  In der Abbildung ist ein Ausführungs  beispiel des Gegenstandes der Erfindung dar  gestellt.     a    ist ein     Spulenkörper    aus einem  für     Hochfrequenzfelder    geeigneten     ferroma-          gnetischen    Stoff, z. B. aus einer Mischung  von Eisenpulver und Isolierstoff. Auf dem  Körper sind mehrere Windungen aus isoliertem       Aluminiumflachdraht    b aufgewickelt. Der     Spu-          lenkörper    kann aus einem einzigen Stück  oder aus mehreren Scheiben hergestellt sein,  von denen dann zwei aussen an der Wick  lung anliegen, während eine oder mehrere  Scheiben als Kern innen in die Wicklung  eingelegt sind.



      High frequency interference suppression choke. The invention relates to high-frequency interference suppression chokes, in particular for strong currents, in which the path of the lines of force runs in a ferromagnetic material suitable for high-frequency fields. So far, such coils made of round wire were wound in several layers on top of and next to each other, mainly to keep the winding capacity low. Since round wire has an unfavorable winding factor, such coils take up a lot of space and are heavy.

    The invention avoids this disadvantage by using a ribbon-shaped conductor which is wound in one plane. Because the winding capacity is increased somewhat, but this is accepted because of the reduction in weight and space saving in vehicles, especially aircraft, for which the subject matter of the invention is mainly intended, especially since with the same coil cross-section the flat wire coil a considerably greater inductance is achieved, as with a round wire coil.



  In the figure, an embodiment example of the subject matter of the invention is provided. a is a bobbin made of a ferromagnetic material suitable for high frequency fields, e.g. B. from a mixture of iron powder and insulating material. Several turns of insulated aluminum flat wire b are wound on the body. The coil body can be made from a single piece or from several disks, two of which then rest on the outside of the winding, while one or more disks are inserted as a core inside the winding.
