IGNITION COIL PROVIDED WITH MEANS FOR LOWERING A MAGNETIC CIRCUIT TO A LOW POTENTIAL

摘要

The invention relates to an ignition coil (1) comprising: - a primary winding (2) that can be powered by charging means (13) that charge the coil (1), - a secondary winding (3) connected to the primary winding (2) by an inter-winding electrical connection (14) positioned between respective first terminals (2a, 3a) of the primary winding (2) and of the secondary winding (3), the secondary winding (3) comprising a second terminal (3b) capable of powering one or more spark plugs, and a magnetic circuit (6) positioned between the primary (2) and secondary (3) windings, characterized in that a protective electrical connection (15) is positioned between the magnetic circuit (6) and the inter-winding electrical connection (14), the protective electrical connection (15) comprising a protective device (7).
