Definitions

  • the present invention relates to an ignition member for a motor internal combustion and, more particularly, such an organ comprising a secondary winding and high voltage output means of said winding secondary, capable of supplying an ignition spark to a cylinder an internal combustion engine.
  • the present invention aims to overcome these drawbacks.
  • the subject of the invention is an ignition member according to claim 1 and a method for producing an organ ignition according to claim 7.
  • the high-voltage output means can include a ceramic base insulating means conducting the housing.
  • the ignition member according to the invention can have a plastic cap between said windings and said high voltage output means.
  • Said housing may include an envelope welded to a piece of ground crimped on a base insulating said high voltage output means said housing.
  • Said case can also form an envelope set on a base the insulator of said high voltage output means.
  • the ignition member according to the invention may include a plug closing said housing opposite to said high voltage output means.
  • the ignition member of FIG. 1 comprises a magnetic core 1 on which is wound a primary winding 2.
  • a secondary winding 3, here of the compartment type, is arranged over the primary winding, concentrically, and receives the secondary winding 4. For clarity, the windings are not shown in Figure 1.
  • the primary winding 2 is powered from a connector 5, and the high voltage output of the winding secondary takes place on an output member 6, here a spring.
  • the "coil” assembly which has just been described is arranged in a housing. 7 provided at its end opposite to the connector 5, with a mounting thread 8 on a motor unit, not shown, and a similar ground electrode 9 to that of a candle.
  • the housing 7 includes screwing means 10 capable of cooperating with an appropriate key to block thread 8 in the corresponding thread of the engine block.
  • a high voltage electrode 11 is mounted in the housing 7 opposite of the ground electrode 9 and is connected to the high-voltage output member 6 by an electrically conductive assembly 12.
  • the high voltage electrode 11 and the conductor assembly 12 are isolated from the housing 7 by a base 13 made of a ceramic of the same type as that of candles ignition.
  • the "coil” assembly previously described is then, in turn, disposed in the housing with the high voltage output member 6 in contact with the end of the assembly conductor 12. Finally, an insulating resin, not shown, is poured into the housing 7 to isolate and maintain the various elements.
