Definitions

  • the invention relates to a diode split transformer for generating the high voltage in television receivers with the features specified in the preamble of claim 1.
  • Diode split transformers are already known in principle and are used to obtain the picture tube high voltage from the check pulses present in the horizontal output stage in the flyback period.
  • the primary winding of these diode split transformers is often implemented as a foil winding, since the prerequisites for a good functionality of the diode split transformer are a good coupling between primary and secondary winding, the presence of a homogeneous magnetic field and a good adjustment to higher order harmonics of the line return frequency. These prerequisites are comparatively easy to meet when the primary winding is implemented as a film winding, whereas they were previously not possible when the primary winding was implemented as a simple wire winding.
  • Diode Split Transformers the primary winding of which is realized as a film winding
  • film winders are required in their manufacture and, on the other hand, the necessary contacting of the films is expensive.
  • the invention has for its object to develop a diode split transformer with the features specified in the preamble of the claim such that the above requirements for a good functionality of the diode split transformer are given without the primary winding having to be constructed as a film winding.
  • the advantages of the invention are in particular that the return of the end of the primary winding through a recess within the second cylindrical bobbin, the distance between the primary and secondary winding down to the corona limit, at which undesirable charge transitions between the secondary and primary side occur can be chosen. As a result, the above requirements for good functionality of the Diode split transformers can be guaranteed. Further advantageous properties of the invention result from the explanation of an exemplary embodiment with reference to the figures.
  • FIG. 1 shows a schematic representation of the primary-side arrangement of a diode split transformer according to the invention.
  • This primary-side arrangement consists essentially of a base 1, a cylindrical coil former 2, the primary winding 3, the core 4 and the connecting pins 5, which are introduced into the base 1 and for the electrical connection between the primary-side arrangement of the diode split transformer and the horizontal output stage serve the television receiver.
  • the base 1 and the coil body 2 can be realized as a one-piece injection molded plastic component.
  • the primary winding 3 is wound as a single-layer solenoid. The end of the primary winding 3 remote from the base 1 is led back to the base 1 and thus to the contact pins 5 through the cylindrical coil former according to an essential feature of the invention. This is illustrated in Figure 2.
  • FIG. 2 shows a schematic representation of the sectional plane x of FIG. 1, which is not to scale. It can be seen that the cylindrical coil former 2 has a recess 6 through which the end of the primary winding remote from the base 1 (see FIG. 1) extends in the axial direction to the base is returned.
  • FIG. 3 shows a schematic representation of the secondary arrangement of a diode split transformer according to the invention.
  • This secondary-side arrangement consists essentially of a hollow cylindrical chamber bobbin 7, which has a larger diameter than the primary-side bobbin 2 and which has separating webs 8 on its outer circumference, the secondary winding 9 and diodes, not shown, via which the individual partial windings of the secondary winding with one another or respectively via which the last partial winding is connected to the picture tube anode.
  • the dividers 8 create on the outer circumference of the Chamber coil body 7 chambers 10 and 11.
  • the individual partial windings of the secondary winding 9 are introduced into the chambers 11 and the diodes, not shown, into the chambers 10.
  • the individual partial windings are at a defined distance from one another.
  • the radial distance of the diodes from the central axis of the chamber coil former 7 is greater than the radial distance of the secondary winding 9 from this central axis.
  • the hollow cylindrical chamber bobbin 7 described above is placed in the axial direction to form the finished diode split transformer on the bobbin 2 shown in FIG. 1 in such a way that the primary and secondary windings lie one above the other in the radial direction.
  • the distance between the primary and the secondary winding can be chosen smaller than in the known diode split transformers. It is only through this possibility of reducing the distance between the primary and secondary windings that even when using a single-layer solenoid Primary winding the above conditions for a good functionality of the diode split transformer can be guaranteed. Furthermore, no foil winding machines are required in the manufacture of the diode split transformer claimed. Finally, the difficulties in contacting the films that occur in film winding technology are also avoided.
