Definitions

  • the invention is based on an ignition coil for ignition systems, especially as a pencil ignition coil in internal combustion engines the type of claim 1.
  • an ignition coil has a cylindrical housing in the basic form.
  • a Winding set arranged, consisting of a primary winding and there is a secondary winding, which windings each coaxially around a central elongated core magnetizable material are wrapped.
  • the housing For the electrical control of the winding set is in the Housing an output stage as a power switching element brought in.
  • the housing is electrical insulating, curable resin filled, which also the Winding set and the power amplifier envelops.
  • the ignition coil according to the invention for ignition systems with the characteristic features of claim 1 has in contrast the advantage that the aforementioned inadequacy is avoided.
  • the ignition coil is designed so that the output stage in a housing part is arranged, which of the housing and thus from the winding set arranged in this as the further heat source of the ignition coil is deposited.
  • This Deposition is embodied by a separating element that Housing from the housing part and thus the two Heat sources thermally decoupled.
  • An ignition coil 11 for ignition systems according to the figure in particular as a pencil ignition coil in internal combustion engines provided for direct contact with a spark plug, the in a usual and not shown manner in one Manhole in a cylinder head of an internal combustion engine is inserted.
  • the ignition coil 11 can also be part of one several ignition coils composed of ignition coil module.
  • the ignition coil 11 contains a coaxial arrangement Longitudinal axis 12 from an elongated cylindrical core 13 magnetizable material as part of an open Magnetic circuit. Concentric around the core 13 is one Low voltage leading primary winding 14 and, radially a high-voltage secondary winding 16 arranged. The two windings 14, 16 form together a winding set 17. With a radial distance to Secondary winding 16 is concentric with the longitudinal axis 12 as Inference element for the magnetic circuit a sleeve-shaped Yoke plate 18 attached.
  • the outer end of the ignition coil 11 forms a cup-shaped housing 19 made of plastic, which in wide Areas has an annular cross-sectional area and with a wall 21 on the inside on the back plate 18 is present.
  • the housing 19 closes in the figure shown end area with a front From opening 22 through which the housing 19 with Components of the ignition coil 11 can be equipped. In this The end region, the housing 19 is expanded radially.
  • the wall 21 forms a bottom 23 of a laterally protruding, shaft-shaped connector 24 in the contact elements 26 for the low voltage supply of the Ignition coil 11 are introduced.
  • the housing part 28 is when the ignition coil 11 is fitted with an output stage 31 in the form of a power transistor busy.
  • the output stage 31 is used to control the current through the primary winding 14.
  • the electrical connections of the Power stage 31 are with the primary winding 14 and Contact elements 26 of the connector 24 over Busbars 32 connected.
  • the output stage 31 is only inside a limited operating temperature.
  • An ignition coil 11 constructed in this way is economical manufacture advantageously and is due to the thermal Decoupling of the two heat sources even under unfavorable ones Operating conditions with regard to external heat in particular reliable.
