Definitions

  • the invention relates to a protective cap for ignition coils according to the preamble of the main claim.
  • the protective cap according to the invention with the characterizing features of the main claim has the advantage that complicated housing parts for receiving the ignition coil and electronic unit are unnecessary and easy assembly is possible. No tools are required for this.
  • An electrically and / or magnetically conductive coating on the surface of the protective cap can also provide a shielding effect against environmental influences and against electromagnetic radiation and radiation.
  • FIG. 1 shows an assembly 7 consisting of an ignition coil 5 and an electronic switching device 6.
  • the protective cap 13 which can be made of plastic, claws with an edge bead 14 on a protruding part of the coil core 8, and can therefore be put on easily and just as easily removed again.
  • the opening 10 nestles against the high-voltage dome 17.
  • FIG. 2 shows how the slotted protective cap 13 nestles against the structural unit 7 to be protected and is fastened by means of a push button 15.
  • the protective cap 13 seals the electrical connections 11 between the electronic switching device 6, the ignition coil 5, the live line connections 12 and the coil core 8. It is also shown that the protective cap 13 has a slot 16 in a partial area and is held together there, for example by a push button 15.
  • the protective cap 13 can be advanced so far that the bushing 18 directly surrounds the high-voltage cable, not shown.
