Title:
IGNITION COIL AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP3891208
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ignition coil with which invasion of moisture to a connector pin can be prevented and the occurrence of short circuit or a contact failure can be prevented with a simple structure, and to provide a method of manufacturing the ignition coil.
SOLUTION: A head 3 in the ignition coil is provided with a case 31, a flange 32 fixed to an engine case, a connector 33 which is electrically connected to an external part of the ignition coil, and a conductive terminal 4 forming a conductive path. The conductive terminal 4 is provided with the connector pin arranged in the connector 33, an exposure contact exposed to the surface of the flange 32, and a coupling part coupling the exposure contact and the connector pin. The terminal is inserted and formed in case resin 311 constituting the case part 31. The coupling part has a conductive projection 43 where a part of the conductive path is projected from within case resin 311. A whole periphery of a cross section in the conductive projection 43 is buried in insulating resin and a remaining part is buried in case resin 311.
