    摘要： An individual ignition type ignition coil for use in an engine in which a center core, a secondary coil wound on a secondary bobbin and a primary coil wound on a primary bobbin are installed concentrically from an inner side of a coil case in order, at upper portion of said coil case a circuit case having a connector is installed inside an ignition unit of the ignition coil, and said ignition coil is connected directly to a respective spark plug of said engine, the ignition coil for use in the engine wherein an insulation resin is filled up between said secondary bobbin and said center core; at an upper end opening of said secondary bobbin said insulation resin is carried out a compression molding and a dent is formed at said upper end opening of said secondary bobbin; in said circuit case having said connector, a bottom portion of said circuit case is communicated to an upper portion of said coil case; a molding resin is filled up extending over from an interior portion of said circuit case having said connector to said secondary coil and said primary bobbin of said coil case and between said primary coil to said coil case; and said dent formed on said insulation resin is buried by said epoxy resin.

    摘要翻译： 一种用于发动机的独立点火型点火线圈，其中中心铁芯，缠绕在次级绕线筒上的次级线圈和缠绕在初级线圈架上的初级线圈从线圈外壳的内侧依次同心地安装在上部 所述线圈外壳的一部分具有连接器的电路外壳安装在点火线圈的点火单元内，并且所述点火线圈直接连接到所述发动机的相应的火花塞，用于发动机的点火线圈包括绝缘树脂 装在所述次级筒管和所述中心芯之间; 在所述次级线圈架的上端开口处，所述绝缘树脂被压缩成型并且在所述次级线圈架的所述上端开口处形成凹陷; 在具有所述连接器的所述电路壳体中，所述电路壳体的底部与所述线圈壳体的上部连通; 填充模制树脂，所述模制树脂从具有所述连接器的所述电路壳体的内部延伸到所述线圈外壳的所述次级线圈和所述初级线圈架并且在所述初级线圈与所述线圈外壳之间; 并且形成在所述绝缘树脂上的所述凹痕被所述环氧树脂掩埋。
