Description

  

  Symmetrische Wicklung, insbesondere für Übertrager- und Relaisspulen.    Symmetrische Wicklungen, insbesondere  für die in der Fernmeldetechnik gebräuch  lichen Übertrager, Relaisspulen oder derglei  chen, werden meist in der Weise hergestellt,  dass die Drähte der zueinander symmetrischen  Wicklungen miteinander     verseilt    auf den  gern aufgebracht werden.  



  Unter     einer        "symmetrischen    Wicklung"  ist eine solche symmetrische Anordnung der  einzelnen     Teilwicklungen    einer Gesamtspule  zu verstehen, bei der die von diesen Teilspulen  ausgehenden elektromagnetischen Wirkungen  unter sich dem absoluten Betrage nach gleich  sind.  



  Diese Herstellungsart hat jedoch den       Nachteil,    dass der zur Verfügung stehende  Wickelraum schlecht ausgenutzt     wird.    In  der     Abb.    1 ist die Stellung von zwei ver  drillten Drähten     gegeneinander    beim Fort  schreiten um eine halbe Ganghöhe des Dral  les im     Querschnitt    wiedergegeben. Man er  sieht daraus ohne weiteres, dass der von einem  Drahtpaar beanspruchte Raum annähernd  demjenigen entspricht, welchen ein Draht mit    einem Querschnitt von der Grösse des die  Einzeldrähte umhüllenden     greises    einnimmt.  



  Ausserdem ist bei verdrilltem Draht die  Kapazität der Wicklungen gegeneinander  verhältnismässig hoch, was in vielen Fällen  nicht     erwünscht    ist.  



  Zweck der Erfindung ist nun,     die    eben  beschriebenen Nachteile zu vermeiden, ohne  die Symmetrie zu verringern. Dies geschieht  in der Weise, dass die Drähte der zueinander  symmetrischen Wicklungen einzeln isoliert,  parallel aneinander gelegt und dann gemein  sam umhüllt werden. Äusserlich haben der  artig umhüllte Drähte die Form. von Flach  drähten.  



  Der Erfindungsgedanke sei an dem Bei  spiel     einer        ,Spule    mit zwei symmetrischen  Wicklungen anhand der     Abb.    2 bis 4 er  läutert. In     diesen    bedeuten 1     die    Drahtkerne,  2 deren Einzelisolation und 3 deren gemein  same Umhüllung.     Abb.    2 zeigt das aus den  Drähten gebildete Band im     Querschnitt,          Abb.    3 in der Ansicht; in     Abb.    4 ist die  Lage der Drahtbänder auf einem Spulen  kern 4 dargestellt.

   Dieses Band lässt sich be-           quem    wickeln und schmiegt sieh eng der Kern  form an, während beim verdrillten Draht  leicht Hohlräume entstehen. Die Kapazität  der beiden Drähte und damit der Teilwick  lungen gegeneinander wird auf ein Minimum  herabgesetzt. .  



  Es ist selbstverständlich auch möglich,  aus erfindungsgemäss angeordneten und ver  einigten Drähten hergestellte     Wicklungen    in  beliebiger Zahl neben- oder übereinander,       nötigenfalls    durch isolierende Zwischen  schichten getrennt, auf einen Kern aufzu  bringen. In dieser Weise beispielsweise her  gestellte     Doppelsprechübertrager,    deren an  sich symmetrisch auszubildende Primär- und    Sekundärseiten aus je zwei zu Drahtbändern  vereinigten Drähten bestehen, zeigen sehr  günstige Eigenschaften.



  Symmetrical winding, especially for transformer and relay coils. Symmetrical windings, especially for the transformers, relay coils or the like in telecommunications engineering, are usually produced in such a way that the wires of the windings that are symmetrical to one another are stranded on the like.



  A "symmetrical winding" is to be understood as such a symmetrical arrangement of the individual partial windings of an overall coil, in which the electromagnetic effects emanating from these partial coils are identical in absolute terms.



  However, this type of production has the disadvantage that the available changing space is poorly used. In Fig. 1, the position of two ver twisted wires against each other while advancing by half a pitch of the Dral les is shown in cross section. It can be seen from this that the space occupied by a wire pair corresponds approximately to that occupied by a wire with a cross-section the size of the old man surrounding the individual wires.



  In addition, when the wire is twisted, the capacitance of the windings against one another is relatively high, which in many cases is undesirable.



  The aim of the invention is now to avoid the disadvantages just described without reducing the symmetry. This is done in such a way that the wires of the windings that are symmetrical to one another are individually isolated, laid parallel to one another and then jointly encased. Externally, the nicely coated wires have the shape. of flat wires.



  The idea of the invention is based on the example of a coil with two symmetrical windings based on Figs. 2 to 4 he explained. In these, 1 denotes the wire cores, 2 their individual insulation and 3 their common sheathing. Fig. 2 shows the band formed from the wires in cross section, Fig. 3 in a view; in Fig. 4 the position of the wire bands on a coil core 4 is shown.

   This tape is easy to wind and hugs the shape of the core, while the twisted wire easily creates cavities. The capacity of the two wires and thus the partial windings against each other is reduced to a minimum. .



  It is, of course, also possible to place any number of windings next to or on top of one another, if necessary separated by insulating interlayers, onto a core made from wires arranged according to the invention and united. In this way, for example, two-way transmitter produced, whose primary and secondary sides, which are to be designed symmetrically, each consist of two wires combined to form wire bands, show very favorable properties.
