Definitions

  • the application relates to a line transformer for television sets, consisting of at least one primary and at least one secondary winding, at least one of which is arranged in an insulating housing and potted with a self-curing synthetic resin, which is housed in a housing and is electrically connected to the high-voltage winding (s) ) connected and arranged in a sliding seat guide of the insulating housing adjuster arrangement.
  • Line transformers in which the windings are arranged in an insulating housing and potted with a self-curing synthetic resin, are known from DE-OS 23 51 130.
  • the known line transformers of this type still have some significant disadvantages.
  • the insulating material housing has the square-shaped adjuster arrangement at the point at which the slide is used seat guide is attached, a corresponding opening.
  • This has the disadvantage that the inside of the adjuster arrangement comes into direct contact with the casting resin when the transformer windings are cast. For this reason, this side of the adjuster assembly must be carefully sealed so that no resin gets into the adjuster assembly.
  • the electrical components in the adjuster arrangement experience an increased thermal load during casting.
  • at least two outgoing lines of the adjuster arrangement must be provided with additional seals, because they are partly in the space filled with resin.
  • the object underlying the invention is therefore to create a line transformer
  • the insulating housing is designed such that the sealing of the interior of the adjuster arrangement and the leads leading from it to the outside, as well as the thermal stress on the adjuster arrangement, is eliminated.
  • the adjuster arrangement should be designed such that the winding and adjuster arrangement individually and can be assembled one after the other.
  • the first object is achieved in that the insulating material housing has a partition between the interior to accommodate the winding (s) to be cast and the adjuster arrangement.
  • the invention has the advantage that the same insulating housing can be used both for line transformers with and without adjuster arrangement. If the insulating housing is used for line transformers with adjuster arrangement, then it is no longer necessary to seal the interior of the adjuster arrangement and the lines leading from it to the outside. In addition, the possible thermal stress on the adjuster assembly is greatly reduced because there is a ventilated space between the partition and the adjuster assembly.
  • the winding (s) of the line transformer can now be inserted into the insulating material housing independently of the adjuster arrangement and can then be connected to the adjuster arrangement in a simple manner.
  • Fig. 1 shows the electrical circuit diagram of a line transformer, which has a primary winding and a plurality of secondary windings. Some of the secondary windings supply auxiliary voltages with a relatively low voltage. A high-voltage secondary winding is also provided, which is subdivided into a plurality of partial windings, between which diodes are connected.
  • This circuit structure makes it clear that it is the circuit diagram of a diode split high-voltage transformer. From Fig. 1 it can also be seen that a voltage is tapped from a partial winding of the secondary winding generating the high voltage and adjustable voltages are generated by means of one or more adjustable resistors, for example the focusing voltage Ufo and the screen grid voltage Ug 2.
  • the winding 2 shows the windings of the high-voltage transformer, which are plugged into one another and then inserted into the insulating housing 1.
  • the winding 2 is the primary winding and the low-voltage secondary windings.
  • 3 denotes the bobbin having a number of winding chambers, on which the windings of the high-voltage secondary winding are wound.
  • On the circumference of the coil body 3 are those between the partial windings of the high-voltage secondary Windings connected diodes 4 arranged.
  • the insulating material housing 1 has the partition 5 on its side facing the viewer in FIG. 1.
  • the sliding seat guides 6 are arranged on two sides of the partition 5, into which the adjuster arrangement 7 (FIG. 3) is inserted.
  • the adjuster arrangement 7 is a cuboid box in which the variable and fixed resistors are arranged according to the circuit in FIG. 1.
  • the lines 8 for the voltages to be dissipated are attached to it.
  • the connections for connecting the adjuster arrangement to the windings of the high-voltage winding are routed to the contact parts 9.
  • the hook 10 connected to the adjuster arrangement can also be seen, which engages behind the nose 11 after the adjuster arrangement has been pushed in and holds the adjuster arrangement in place until a final fastening takes place by the potting.
  • the line transformer is already provided with the ferrite core 12.
