摘要： In a stick coil, there is disclosed an ignition coil for an internal combustion engine which can prevent a crack (a collar leak) from being generated due to a thermal stress. In this ignition coil, the structure is made such that a size (L) of a portion which is in parallel to an axial direction of a primary spool (121) in a projection portion (121b) is larger than a size (T) of a portion which is in parallel to an orthogonal direction to the axial direction of the primary spool (121). Accordingly, a frontal projected area of the projection portion (121b) as seen from a flowing direction of a resin becomes small, a resin flow is hard to get out of order at a time when the resin flows through a portion corresponding to the projection portion (121b) at the forming time, and a convoluted void and a weld are hard to be generated. Accordingly, since it is possible to prevent a mechanical strength in a root portion of the projection portion (121b) from being reduced, it is possible to previously prevent a crack from being generated in the root portion of the projection portion (the collar portion) (121b) due to a thermal stress so as to reduce an insulating property.

摘要： An ignition coil that can be easily assembled, that assures co-axial alignment of a primary coil, a secondary coil and a center core part, and that generates desired high voltage. A core body is formed to have an outer diameter larger than that of a permanent magnet so that the permanent magnet will not protrude out of the outer peripheral face of the core body. Accordingly, when the center core part is inserted into a secondary spool, the center core part is not caught by the secondary spool and may be readily inserted and assembled therewith. Also, because no bulge is created at the center core part, it is possible to prevent the center core part from tilting within the secondary spool and to readily assure the co-axial alignment of the primary spool, the secondary spool and the center core part. Thus, voltage generated by the secondary coil is prevented from dropping, and high voltage may be applied to the ignition plug.
摘要翻译： 可以容易地组装的点火线圈，其确保初级线圈，次级线圈和中心芯部分的同轴对准，并且产生期望的高电压。 芯体形成为具有大于永久磁铁的外径，使得永磁体不会从芯体的外周面突出。 因此，当中心芯部分插入次级线轴时，中心芯部分不被二次线轴卡住，并且可以容易地插入和组装。 此外，由于在中心芯部没有产生凸起，所以可以防止中心芯部在二次线轴内部倾斜，并且容易地确保初级线轴，次级线轴和中心芯部分的同轴对准 。 因此，防止由次级线圈产生的电压下降，并且高电压可能被施加到火花塞。

摘要： In a stick-type ignition coil device for engines, a primary spool is disposed outside a secondary coil. The primary spool is made of PBT (polybuthylene telephthalate) having a low melting viscosity and a high flowability as a resin base material. The resin base material is admixed with an olefin rubber in 5 wt. %, glass fibers in 12.5 wt. % and silica in 12.5 wt. %. A primary coil 24 comprises a wire body coated with PET (polyethylene telephthalate), silicone or wax as a separating member, and is wound around the primary spool. The growth of trees in the primary spool 23 restricted even when electrical discharges occur between a secondary coil and the primary coil and the primary spool is eroded by the electrical discharges, because silica is added in the primary spool.
