Definitions

  • the aim is to combine inductors in such a way that two coils are wound on a bobbin.
  • the invention relates to such a coil arrangement (duo coil) having two coils on a common coil former.
  • Combination coils of the aforementioned type are already known from EP-B-0 171 690. These known coils have a number of disadvantages. With them, the windings are almost 100% coupled, making adjustment difficult. Furthermore, the inevitable manufacturing tolerances require a high level of measurement and result in a high reject rate, since it is practically impossible to make improvements. In addition, the windings are heated by eddy current losses caused by the other field. Finally, the required damping of the driver circuit must be realized by means of the external load resistor.
  • the invention has for its object a coil arrangement to create the type mentioned, which avoids the aforementioned disadvantages of the known coils of this type with otherwise the same effect in the circuit.
  • the individual coils, each with its own core, if necessary, are arranged at a considerable mutual distance on the common coil body, as a result of which the coupling is minimized. If necessary, the remaining coupling is reduced to a negligible value by an uncritical opposing winding.
  • duo coil according to the invention is explained in more detail below using an exemplary embodiment with reference to the drawing.
  • Fig. 1 and Fig. 2 show the duo coil schematically in side view and partly in section.
  • Fig. 3 shows the circuit diagram of the windings of the two coils of the duo coil.
  • the duo coil has a bobbin 1 with a foot and connecting pins.
  • the coil former 1 is provided with four flanges 2, which form two winding chambers 3 and 4. 2 shows the relative position of two cores 9 and 10 in the coil former 1 and the distribution of the windings from FIG. 3 in the winding chambers 3 and 4.
  • the actual vertical winding W3a from FIG. 3 is designated by 5, which continues in the compensation winding 8 designated by W3B in FIG 3 accommodates secondary driver winding 6, designated W1, and a primary driver winding 7, designated W2 in FIG.
  • the arrangement of the compensation winding 8 in the winding chamber 3 creates the effect that the end of this winding comes to rest on the foot of the coil former.
  • Coil arrangements according to the invention can e.g. can be used as driver and vertical deflection integration coils or as coupling and bridge coils for the east-west diode modulator in image viewing devices.
