METHOD OF PRODUCING AN INDIVIDUAL IGNITION COIL AND COIL THUS OBTAINED

摘要

The invention relates to a method of producing an individual ignition coil for a plug (2) of an internal combustion heat engine with controlled ignition. The inventive method comprises the following steps consisting in: coiling a secondary winding (15) around a tubular secondary coil body (11); and coiling a primary winding (23) concentrically around the secondary winding (15), the aforementioned two windings being electrically isolated by means of a dielectric material. The method also comprises an over-moulding step in which the tubular body (11)/secondary winding (15) assembly is over-moulded with a dielectric material, such as to ensure impregnation of the secondary winding and the formation of: (i) a tubular primary coil body (21) that is adapted to enable the coiling of the primary winding (23) during a subsequent step; and (ii) an end piece (211) for connecting to a plug that extends out from the tubular primary coil body (21) at one of the ends thereof.
