Abstract (en)

[origin: WO9936693A1] The invention relates to a stick coil (11) for ignition systems, more particularly a stick coil used as ignition coil for internal combustion engines in automobiles. The invention aims at reducing the interference voltage resulting from ignition processes. The stick coil (11) has a core (14) shaped as an I-type core, a tubular recoil closing plate (15) and a primary connection (18). A first electrically grounded contact element (19) is located in the primary connection (18). The first contact element (19) forms part of a power rail (21), which is electrically connected to the recoil closing plate (15) by means of a resistor element (23) or a plate strip (24) so that the interference voltage produced therein is diverted to ground potential. The inventive stick coil (11) is preferably used in automotive manufacturing.
