Title: Ignition coil
Inventor: NAGATA TAKASHI
IPC: H01F38/12
Filed: 2002-03-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide an ignition coil with a long thermal cycle life.  <P>SOLUTION: The ignition coil comprises a resin insulating material, a primary coil part constituted by winding a primary winding wire coated with a primary coating material buried in the resin insulating material, and a secondary coil part constituted by winding a secondary winding wire coated with a secondary coating material buried in the resin insulating material and placed concentrically with the primary coil part. The ignition coil is inserted into a plug hole of a cylinder. A glass transition temperature (Tg) of the resin insulation material is 130°C or below. The Young's modulus of the resin insulating material is small when a temperature of the resin insulating material becomes Tg or above. That is, the resin insulating material becomes soft. Thereby, in a usage environment temperature range (ΔT) for the resin insulating material, heat stress generated between the resin insulating material and an adjacent member is absorbed by the deformation of the resin insulating material in a range of Tg-highest temperature (TH). Thus the thermal cycle life is long.  <P>COPYRIGHT: (C)2003,JPO
