  • Ignition coil for motor vehicles
    Patent number: 6636138
    Abstract: An ignition coil for a motor vehicle, 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 are set coaxially with respect to the magnetic core. The coil includes 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. A diode (42) is set at one end of the high-voltage spool (16) and has both 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).

  • Ignition coil for motor vehicles
    Patent number: 6483410
    Abstract: An ignition coil for motor vehicles, comprising: a magnetic core (12) having a rectilinear axis; a secondary spool (16) supporting a high-voltage winding (18) and being set coaxially with respect to the magnetic core (12); a primary spool (20) supporting a low-voltage winding (22) and being set coaxially with respect to the secondary spool (16) and outside the latter; a tubular-shaped outer casing (24) which encloses the assembly comprising the magnetic core (12) and the spools (16, 20); and a low-voltage connector (28) including a connector body (30) made of plastic material and a plurality of metal contacts (32) fixed to the connector body (30). In the ignition coil, the connector body (30) is made of a single piece with the primary spool (20).
