Title:
IGNITION COIL FOR INTERBAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2017/047390
Kind Code:
A1
Abstract:
An ignition coil 1 for an internal combustion engine according to this embodiment has a primary coil 11, a secondary coil 12, a center core 13, an outer peripheral core 2, an igniter 3, a case 4, a connector section 5, and a relay member 6. The relay member 6 electrically connects the outer peripheral core 2 and a grounding terminal member 52. The relay member 6 has: a base section 61 disposed along the rear surface of an engagement wall 50; a rising section 62 rising rearward from the base section 61; and a curved section 63 curved so as to protrude rearward, the curved section 63 being extended from the rear end of the rising section 62 in the vertical direction Z perpendicular to the coil axis direction X. The base section 61 is in contact with a grounding inner terminal at one end of the base section 61 in the vertical direction Z. The rising section 62 is disposed outside the igniter 3 in the horizontal direction Y. The curved section 63 is in pressure contact with the front surface 211 of the outer peripheral core 2 while being elastically deformed.
