Definitions

  • the invention relates to a chamber coil former for insertion into printed circuit boards, preferably for a switching power supply transformer of a television set, a double U core being insertable into the coil former and the transformer having a metallic shielding jacket.
  • the object of the invention is therefore to provide a bobbin structure for a switching power supply transformer of a television set which, after winding the bobbin and completing the required electrical insulation values and safety distances between the primary and secondary winding and other parts (transformer core, circuit board), without additional insulation measures (z. B. pouring the transformer) guaranteed.
  • the bobbin should also be constructed so that automatic winding and plugging together is possible and that a metallic shielding jacket can still be placed over the windings.
  • FIG. 1 shows a perspective view in the pulled-apart state of a coil body, which consists of a plurality of coil body parts which can be plugged into one another coaxially.
  • the complete chamber bobbin 1 sits according to the drawing shown composed of three different body parts.
  • a coil body part 3 and 4 can be coaxially inserted into each other on both sides so that a coil body block connected in itself is formed.
  • the bobbin parts 3, 4 have inner and outer side flanges.
  • solder pins 7, 8 are used in the outer side flanges.
  • the solder pins 7, 8 and the plastic part of the side flange of the bobbin parts 3, 4 carrying them are additionally designed so that the individual connecting wires of the windings applied later can also be soldered to the solder pins, even before the bobbin parts 3, 4 are inserted into the center piece 2, ie already on the winding machine.
  • the windings of the middle piece are carried out only after the coil former has been joined together and the wire ends are wound or soldered onto solder pins of the coil former parts 3, 4.
  • the inner coil flanges 9, 10 of the coil body parts are matched so that they fit coaxially into one another and into the center piece 2.
  • the bobbin parts 3, 4 and the center piece 2 have winding chambers of different sizes on, which are formed by appropriate dividers.
  • One or both bobbin parts 3, 4 and the middle part 2 have a latching device in the form of resilient latching hooks 11, which make it possible for the individual parts of the bobbin to be joined together to form a bobbin block.
  • a double U core which is preferably designed as a ferrite sintered part, can be inserted into the core openings of the coil body block.
  • One side leg of the U-core is partially surrounded on both sides by a wall 12 on the side flange 5.
  • the coil body openings have a rectangular cross section for receiving the coil core.
  • the structure of the coil body is independent of the geometry of the coil core; cores with different cross-sections, e.g. B. square or round can be selected and used. An adjustment of the coil body opening is required here.
  • the individual coil body parts and the center piece can, if necessary, be divided into winding chambers of different sizes by any separating webs 13, 13 ', 13 ".
  • the two side flanges 14, 15 of the coil body center part 2 are designed such that they embrace the outer leg of the U-core
  • the inner sides of the side flanges 14, 15 have a circumferential shoulder 16, into which a metallic shielding jacket which can be wound over the coil former can be inserted support the shielding jacket from the inside.
  • Figure 2 shows the wound bobbin, which with the other parts, for. B. a double U-core 17 and a metallic shielding jacket 18 to a complete switching power supply transformer of a television set.
