摘要： A stick-type ignition coil have a central core, a cylindrical member, primary spool, primary coil, secondary spool, secondary coil, outer core and a resin insulator. The two longitudinal end corners and faces of the core are covered by respective buffer members. The inner circumferential corners of the outer core is supported by ring members. Some of the members disposed radially inside and other members disposed radially outside of the inside members are held slidably to each other in the ignition coil. The spools are made of resin containing a rubber in excess of 5 weight percent and reinforcing materials. The resin insulator contains a flexible material.

摘要： An ignition coil has a coil case made of an insulating resin, including a head portion, a cylinder portion accommodating a primary coil, and a secondary coil and a high-voltage tower portion for fitting with a spark plug. At least one of those three portions is separately molded and then the portions are assembled to form the coil case. The longitudinal length of each of the three portions is less than a forming flow length of the insulating resin, thereby preventing inferior molding. Further, the structure of each molding die is simpler than that of the coil case for an integral molding. Therefore, the coil case of the ignition coil can be molded readily without molding defects, even when the coil case is elongated, formed thinner, and/or formed with an undercut portion.

摘要： A high voltage post terminal is accurately located within a support aperture during manufacturing processes by at least one inwardly directed projection to avoid assembly problems caused by sizing the entire aperture itself to locate the terminal with sufficient accuracy. By thus improving the concentricity of the high voltage coil components it is possible to achieve more reliable insulation between components at even relatively small-sized coils used for individual engine plug holes. An especially advantageous range of critical parameters has been discovered as achievable by using this more reliable manufacturing process.

摘要： A traverse shaft section 609 shifts in response to the rotation of a bobbin rotating section 604 with a predetermined winding pitch P1 equivalent to two to 10 times the diameter of a wire rod 520. With this shift movement of traverse shift section 609, wire rod 520 extracted from a winding nozzle section 610 shifting together with traverse shaft section 609 is wound spirally along a slant surface 530 formed by a first winding section 541 at the winding pitch P1 equivalent to two to 10 times the diameter of a wire rod 520. As a result, an advancing-side wire rod 520a and a reversing-side wire rod 520b cross over each other at opposing inclinations. Hence, it becomes possible to prevent the reversing-side wire rod 520b, when wound on the advancing-side wire rod 520a, from pulling and dislocating the advancing-side wire rod 520a from its regular winding position, thereby eliminating undesirable winding collapse.

摘要： An ignition coil for an internal combustion engine, having a seal between the ignition coil and a plug hole of the engine. An air passage is provided only on a head portion and a pipe portion of the ignition coil to permit air to pass. Pressure change in the plug hole can be equalized with the atmosphere through the air passage. Therefore, it becomes easy to make the seal and to attach the seal to the ignition coil because the seal does not have any air passage.
