Definitions

  • the invention relates to a distributor rotor according to the preamble of the main claim. It is already known (according to DE-PS 3 131 884) a distributor rotor lying in this direction, in which the unit prefabricated from the distributor electrode, the contact electrode and the interference suppression resistor is inserted into a recess in the insulating body and this recess is then poured out with casting resin. This pouring out requires a relatively large outlay in terms of production technology.
  • the distributor rotor according to the invention requires less production engineering effort.
  • the distributor rotor according to the invention is characterized by special high-voltage strength, which is particularly advantageous where the distributor rotor is to be screwed directly onto the end face of the camshaft belonging to the internal combustion engine.
  • Such distributor rotors are used in ignition systems in which the ignition timing is adjusted electronically.
  • high-voltage flashovers occur easily between the fastening screws connected to ground and the contact electrode connected to high voltage, which results in ignition failure and is avoided with certainty in the distributor rotor according to the invention .
  • FIG. 1 shows a plan view of a distributor rotor according to the invention
  • FIG. 2 shows a section along section line II, II in FIG. 1
  • FIG. 3 shows a section along section line III-III in FIG. 1
  • FIG. 4 shows a section along section line IV- IV in Figure 1.
  • the distributor rotor shown in the drawing is intended for the ignition distribution in a not shown Internal combustion engine to be determined.
  • the distributor rotor has a distributor electrode 1 which, during operation, is to be movable in a circular orbit 2 and should be able to be guided past fixed electrodes 3 connected to spark plugs (not shown).
  • the distributor rotor is provided with a contact electrode 4 located in the center of the orbit 2, to which high-voltage pulses are supplied by an ignition coil, also not shown, by means of a sliding contact, not shown.
  • An interference suppressor 5 is inserted between the distributor electrode 1 and the contact electrode 4 in terms of construction and circuitry.
  • the distributor electrode 1, the interference suppression 5 and the contact electrode 4 form a prefabricated structural unit which is received by an insulating body 6.
  • This insulating body 6 is produced by injection molding and in the preferred case consists of polyester. During the manufacture of the insulating body 6, the structural unit prefabricated from the components 1, 4, 5 is immediately injected.
  • the interference suppression 5 is provided on its end faces with fixed contact caps 8, 9.
  • the contact caps 8, 9 can be fastened by beads 10 which run in the circumferential direction of these caps 8, 9 and are indicated by dashed lines 10.
  • the contact electrode 4 consists of a round contact plate 11 and a contact strip 12 which continues at least almost in the plane of this plate, the free end of which is bent up and fastened to the end face of the contact cap 11 by a rivet connection 13.
  • the distribution electrode 1 has one bent section, which is fastened by a rivet connection 14 to the end face of the contact cap 9.
  • the resistance carrier 15 is made of epoxy resin and a glass fiber additive.
  • a flange 16 provided on the insulating body 6 with inserted screw bushings 17 is used for fastening to a counter flange, not shown, which is to be located on the end face of the camshaft, also not shown, of an internal combustion engine.
  • the contact plate 11 of the contact electrode 4 is located on the bottom of a blind hole 18 tapering towards the plate 11, that the insulating body 6 also surrounds this blind hole 18 with an insulating collar 19 and that finally - when looking into the blind hole 18 - the
  • the level of the contact plate 11 and the adjoining contact strip 12 is lower than the imaginary longitudinal central axis of the interference suppressor 5, the electrical flashover resistance between the contact electrode 4 and the screw sockets 17 or the fastening screws screwed therein but not shown is particularly high.
