Abstract:
An ignition coil for motor vehicles, comprising:a magnetic core (12) having an elongated shape; a primary spool (20) supporting a low-voltage winding (22), and a secondary spool (16) supporting a high-voltage winding (18), the two spools being set coaxially with respect to the magnetic core; a tubular-shaped outer casing (24) carrying, at a first end, a low-voltage connector (28) and, at a second end, a high-voltage connector (30) which is designed to connect with a spark plug; and a diode (42) set at one end off the high-voltage spool (16) and having a first rheophore (44) which is electrically connected to one end of the high-voltage winding (18), and a second rheophore (46) which is electrically connected to the high-voltage connector (30); characterized in that it comprises a diode-supporting member (48) attached at the one end of the secondary spool, the diode-supporting member including one or more anchoring elements against which at least one of the rheophores are bent to fix the diode in place on the diode-supporting member.
