Claims

[Scope of utility model registration request]

A secondary coil, which is divided and wound around a secondary bobbin having a plurality of grooves, is arranged outside the primary coil wound on the primary spool, and the primary coil and the secondary coil are placed in a case together with the core and the high voltage terminal. In molded ignition coils for internal combustion engines, epoxy resin is injected and heated to harden after being inserted and fixed inside.
A plurality of pawls and a recess are provided on the inner side of the secondary bobbin to engage with the collar of the primary bobbin, and further a plate-like protrusion that engages with the recess of the secondary bobbin is provided on the tail of the primary spool. A molded ignition coil for an internal combustion engine, wherein the primary spool and the secondary bobbin are mutually positioned and fixed in the axial direction.
