摘要： In order to prevent a crack of plastic parts caused by a shrinkage force of a resin filler filled in an ignition coil casing, a cylindrical coil casing houses a primary coil and a secondary coil concentrically, and the resin filler such as epoxy resin is filled in the coil casing to insulate between the parts in the coil casing and to fix the parts. A ring-shaped partition member is provided at the upper portion in the coil casing to separate the resin filler locating above the primary coil and the secondary coil inside and outside. The partition member is made of a resin whose adhesive strength against the resin filler is weak, such as polypropylene (PP). The partition member reduces the shrinkage force between the outside resin filler and the inside resin filler, and prevents a crack of plastic parts, such as the secondary spool.

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.

摘要翻译： 点火线圈具有由绝缘树脂制成的线圈壳体，包括头部，容纳初级线圈的圆筒部分和次级线圈以及用于与火花塞配合的高压塔架部分。 这三个部分中的至少一个被单独模制，然后这些部分被组装以形成线圈壳体。 三个部分中的每一个的纵向长度小于绝缘树脂的形成流动长度，从而防止劣化成型。 此外，每个成型模具的结构比用于整体成型的线圈箱的结构简单。 因此，即使当线圈壳体细长，形成较薄，和/或形成有底切部分时，也可以容易地模制点火线圈的线圈壳体而不造成模制缺陷。
