Definitions

  • the present invention relates to an ignition distribution rotor, in particular for a motor vehicle.
  • Such ignition distribution rotors are increasingly equipped with a so-called anti-interference resistance placed between an electrode and a contact part to form a spark gap.
  • This type of spark gap is generally obtained by crimping the electrode and the contact piece at the ends of the resistor, which requires significant storage of the various constituent elements separately before assembly.
  • the object of the present invention is to remedy this drawback and to this end relates to an ignition distribution rotor for an internal combustion engine, comprising a spark gap of the type comprising a resistor inserted between an electrode and a contact piece, characterized in that the resistance consists of an insulating support obtained by overmolding of insulating material on anchoring lugs produced respectively on the electrode and the contact piece and around which is wound a resistant wire whose ends are fixed by soldering on lugs made respectively on the electrode and the contact part.
  • a distribution rotor 9 comprises in a housing a spark gap 1 constituted by a resistor 4 disposed between a contact piece 2 and an electrode 3; see e.g. DE-A-1123866.
  • the spark gap 1 consists of an insulating support 12 of preferential cylindrical shape obtained by overmolding of insulating material on anchoring lugs 5 produced respectively on the electrode 3 and the contact piece 2, and d a resistant wire 7 wound around the insulating support 12 and the ends of which are fixed by welding respectively on lugs 6 produced respectively on the electrode 3 and the contact piece 2.
  • the contact parts 2 and the electrodes 3 are obtained by cutting from the same strip 10 of conductive material and are held in a frame 8 in a position between them, equivalent to their functional position, by bridges 11.
  • Each electrode 3 has an anchoring lug 5 facing an anchoring lug 5 produced in the contact part 2.
  • each of the electrodes 3 and the contact parts 2 has a lug 6.
  • the insulating support 12 is then molded onto the anchoring lugs 5 and then the cut-off bridges 11.
  • the resistant wire 7 is then wound around the insulating support 12 and its ends are welded respectively to a tab 6 of the electrode 3 and to a tab 6 of the contact piece 2.
  • the resistance thus formed by the insulating support 12 and the resistant wire 7 can then be impregnated with varnish in order to facilitate the manipulation of the elector towards its housing in the rotor 9.
