    • An ignition coil device is provided in which a damaged portion can be exchanged and which requires no connector for connecting a power switch with a wiring harness. Since an ignition coil device 2 is constructed such that a primary coil portion 21 and a power switch 22 are secured by fitting the primary coil portion 21 into a hollow core of a secondary coil portion 23 mounted in advance on an engine 30, the primary and secondary coil portions 21, 23 can be detachably connected via an iron core 21c as a magnetic core. Accordingly, only the secondary coil portion 23 having a relatively short life due to the generation of varying high voltage can be easily exchanged. Further, since the power switch 22 and the primary coil portion 21 are integrally or unitarily connected with a wiring harness 40, the construction can be made inexpensive and simple by the deletion of a connector provided in a prior art ignition coil device, thereby enhancing electrical reliability.
    • 提供点火线圈装置,其中可以更换损坏的部分,并且不需要用于将电源开关与线束连接的连接器。 由于点火线圈装置2被构造成使得初级线圈部分21和电源开关22通过将初级线圈部分21装配到预先安装在发动机30上的次级线圈部分23的中空芯中而被固定, 次级线圈部分21,23可以经由作为磁芯的铁芯21c可拆卸地连接。 因此,只有由于产生变化的高电压而具有相对较短寿命的次级线圈部分23可以容易地更换。 此外,由于电源开关22和初级线圈部分21与线束40整体或整体连接,所以通过删除现有技术的点火线圈装置中提供的连接器,可以使结构变得便宜和简单,从而增强电气 可靠性。
