Abstract

1. Process for the construction of an ignition coil for internal combustion engines, the coil comprising a closed magnetic circuit (1), around one of whose branches there are arranged a primary winding (3) and a secondary winding (5) which are housed in a case (7) filled with a cast insulating material (8) covering the base of at least one high-voltage output terminal (9) maintained on the case (7) and equipped with a metal member (10) connected via an electrical connecting component (11) to the end (5a) of the secondary winding (5), which process is characterised in that the high-voltage output terminal (9) comprises a cam (14) and lobes (15) so that when a rotary motion is imparted to the said terminal, the said lobes exert a pressure maintaining this terminal on protrusions (16) arranged inside the case (7) so as to immobilize the terminal (9) in the case (7) before and during the operation of casting the insulating material filling the case.
