摘要： An ignition coil for supplying a high voltage to a spark plug is mainly composed of a cylindrical casing, an outer coil wound around an outer spool and an inner coil wound around an inner spool. The outer coil wound around the outer spool and the inner coil wound around the inner spool are coaxially disposed in the cylindrical casing. Spaces in the cylindrical casing including a first space between the inner coil and the outer spool and a second space between the outer coil and the cylindrical casing are filled with insulating resin. After the resin is supplied into the cylindrical casing, the coils are inserted into the casing containing the resin therein. Accordingly, the resin can be quickly supplied from a wide opening, and the resin can enter into spaces between coils even these spaces are small.

摘要翻译： 用于向火花塞提供高电压的点火线圈主要由圆柱形壳体，缠绕在外线圈上的外线圈和缠绕在内线轴上的内线圈组成。 缠绕在外线轴上的外线圈和卷绕在内线轴上的内线圈同轴地设置在圆柱形壳体中。 在圆筒形壳体中的包括内部线圈和外部线轴之间的第一空间以及外部线圈和圆柱形壳体之间的第二空间的空间填充有绝缘树脂。 将树脂供给到圆筒形壳体中之后，将线圈插入包含树脂的壳体中。 因此，可以从宽的开口快速地供给树脂，并且树脂可以进入线圈之间的空间，甚至这些空间也很小。
