IGNITION COIL FOR A VEHICLE

摘要

An ignition coil for a vehicle is provided to prevent electrical disconnection between the ignition coil and a spark plug and eliminate the process of assembling a pressure spring. An ignition coil(1) for a vehicle includes a compression spring(10), a high pressure terminal(20), a second spool(30), and a case(40). The compression spring is electrically connected to a spark plug(50). The high pressure terminal has one end where the compression spring is connected such that the high pressure terminal transmits voltage to the spark plug. The second spool is press-fit with the high pressure terminal. The case is filled with an insulation material for preventing leakage of current, and has a lower surface on which a high pressure tower(40a) is formed. The compression spring has a cylindrical shape, and is insert-molded to an inner surface of the case. The compression spring has a lower portion which is bent outwardly to press the spark plug.
