Abstract

The invention provides an iron core for an ignition coil for an internal combustion engine and an ignition coil for an internal combustion engine, which can prevent performance degradation caused by stress. An outer peripheral iron core part (15) arranged on the outer periphery of a second framework in the iron core (10) is a component formed by laminating square flat iron core sheets in the direction away from a central iron core part (11), and is formed by combining four planar laminated bodies (16) (laminated parts (18, 19, 20, 21)).

Description

technical field [0001] The present invention relates to an iron core for a coil used in an ignition coil for an internal combustion engine for generating spark discharge in a spark plug of an engine such as an automobile, and an ignition coil for an internal combustion engine. Background technique [0002] Ignition coils for internal combustion engines transform the battery voltage into high voltages required for spark discharge by spark plugs, and are installed in engines such as automobiles. An ignition coil for an internal combustion engine has an ignition coil body that generates a high voltage, and a socket that is connected to the ignition coil body and supplies the high voltage to a spark plug. [0003] The main body of the ignition coil is a component in which a coil and an iron core are combined and housed in an insulating case. The primary coil is wound on the cylindrical primary bobbin, and the secondary coil is wound on the cylindrical secondary bobbin. The pri...
