コイルは磁石回転子側に配置される。[Prior art] As an ignition device for an internal combustion engine, an exciter coil that generates voltage in synchronization with the rotation of the engine is used as a power source, and the current supplied from the exciter coil to the primary side of the ignition coil is controlled by an interrupter or a semiconductor switch. The ignition operation is performed using the following methods. In an ignition system used for a small general-purpose internal combustion engine, a so-called wither type ignition system is used in which an exciter coil and an ignition coil are provided within a magnet generator in order to save space and reduce weight. This type of ignition device, which has been widely used in the past, consists of a generator consisting of a primary coil and a secondary coil of the ignition coil wound around a U-shaped iron core, and an exciter coil wound around a separate iron core. The generator was placed on the stator side of the magnet generator, but this structure requires separate iron cores for the ignition coil and exciter coil, which increases the number of parts such as the iron core and bobbin. This increases the number of man-hours required for assembly, and also increases the weight of both coils and the space occupied by both coils, making it difficult to meet the demand for smaller size and lighter weight. Therefore, it was considered to wind the ignition coil and exciter coil around a common iron core. In this type of generator, the ignition coil that generates high voltage is placed away from the magnet rotor to facilitate connection with the high voltage cord, and the exciter coil that produces a low output voltage is placed on the side of the magnet rotor. be done.

る。[Problems to be solved by the invention] Considering the insulation between the ignition coil that generates high voltage and the exciter coil, the connection between the coil end of the exciter coil and the lead wire drawn out to the outside should be made as far as possible from the ignition coil. This will be done near the end of the exciter coil on the far side of the magnet rotor. In order to easily connect the external cord to the generator, it is preferable that the connecting portion of each coil be placed at the end on the ignition coil side to which the high voltage cord is connected. Therefore, from near the end of the exciter coil on the magnet rotor side, the lead wire from the exciter coil is connected to the designated lead-out point without contacting the magnet rotor and without being affected by the high voltage from the ignition coil. In order to route the lead wire up to this point, a troublesome clamping process is required to securely fix the lead wire through an insulating member.

を要する。 In order to avoid the troublesome clamping process and to reliably prevent contact between the magnet rotor and the lead wire, extend the lead wire from the exciter coil to the side where the high voltage cord connected to the ignition coil is connected. It is conceivable to house the generator including the lead wire in a case, or to perform a molding process. However, in order to house the generator including the lead wire inside the case, it becomes necessary to provide an insulating partition inside the case to insulate the lead wire from the high voltage of the ignition coil, which causes the problem of increasing the size of the generator. There is. In addition, when performing cast molding or case molding, it is necessary to perform the molding with the lead wire from the exciter coil separated from the ignition coil in order to insulate it from the ignition coil. The case requires complicated ingenuity.

る。[Effect of the invention] As described above, according to the invention, the external lead-out terminal conductor for the exciter coil is embedded in the body of the bobbin and the first flange, and one end of the external lead-out terminal conductor for the exciter coil is embedded in the first flange. The ignition coil is connected to the exciter coil by protruding outward from the flange thereof, and the other end is made to protrude outward from the end opposite to the end where the second flange of the ignition coil winding part is provided. Therefore, electrical connection to the exciter coil can be made without the need for the troublesome clamping process that takes into consideration prevention of contact between the lead wire from the exciter coil and the magnet rotor and insulation from the ignition coil, which was conventionally performed. A connection for the ignition coil can be arranged at the end on the ignition coil side. In addition, even when the generator is housed in a case, there are no lead wires routed outside the coil, so there is no need to use a large and complex case with an insulating partition, and a compact generator can be provided. can do. Furthermore, even when molding is performed, the molding process can be easily performed without requiring any special measures for the mold die or the like.
