ABSTRACT:
An ignition coil (1) for internal combustion engines comprises a magnetic core (4) of the core- of sleeve type, around the main core of which the primary and secondary winding being insulatingly enveloped with a cast material is arranged, the end regions of the main core being connected with each other via a magnetic path located outside the two windings, and having mounting members attached to the magnetic core (4) for mounting the ignition coil (1) to an automobile body. In order to bring the heating of the windings to an equal level and to reduce the heating of the windings, the mounting members are formed of a mounting plate (8) with mounting surface (9) and of at least one frame member (10, 11) integrally formed with the mounting plate (8) which envelopes the magnetic core (4) in a form-locking manner. The frame members (10, 11) can be expediently placed for mounting angularly on the ignition coil (1) and are pivotable in abutment with the surface of the magnetic core (4).
