摘要： In an ignition coil assembly, a plurality of ignition coils is arranged to be electrically connected to spark plugs received in plug holes of an engine. A base cover includes a plurality of receiving through holes, which are arranged at corresponding positions that correspond to positions of the plug holes, respectively. A top cover covers a top surface of the base cover and secures each ignition coil through engagement with the head of each ignition coil. Fastening bolts temporarily fasten the top cover and the base cover in a manner that allows sliding adjustment of a securing position of each ignition coil, which is loosely received in a corresponding one of the base cover through holes, in an imaginary plane that is perpendicular to an axis of each ignition coil.

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.

摘要： An interesting coil supporting unit for an engine includes an elongated casing and a plurality of coil units. Each coil unit has a coil support portion and an ignition coil. The coil support portions are disposed inside the casing at predetermined intervals. The casing and the respective coil support portions are fastened to a cylinder block by means of a plurality of bolts. In this state, each coil unit is supported by the corresponding bolt so as to be slidable in its radial direction. Therefore, the coil units can be positionally slid in the casing and thereby installed easily on the engine.

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： An ignition coil includes a housing which contains a central core portion, an inner spool having a first winding, and an outer spool having a second winding. The inner spool extends outward of the central core portion. The outer spool extends outward of the inner spool. A locating member includes a locating rib adjacent to an upper portion of the central core portion. The locating rib is in a gap between the inner spool and the central core portion, and locates the inner spool and the central core portion relative to each other. Insulating resin injected into the housing provides insulation among parts in the housing. At least one of the inner spool and the locating member has a void-escape passage which connects the gap and an outside of the inner spool with each other, and which allows a void to escape from the injected insulating resin in the gap.

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： A stick-type ignition coil device has a central core, and primary and secondary windings wound concentrically around the central core in a coil casing. A positioning part is provided in the casing to define the position of the central core. An insulating resin such as epoxy resin is filled in the coil casing for electrical insulation and fixing of components in the coil casing. A thermal stress releasing member, which is less adhesive to and easily peelable from the insulating resin, is provided on the upper surface of the positioning part. The thermal stress releasing member is separated from the insulating resin and allows the positioning member to move with the central core, thereby minimizing cracks which will occur in the insulating resin formed between the central core and the positioning part.

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。
