It consists of an iron core 5 incorporated through 4. The molded coil 3 has a total of four high-voltage terminals 11-14, two on each side of the upper surface, and fuses 6 are installed between the two terminals 11-12 and 13-14 on the left and right sides, respectively. , a high voltage coil 1 is internally connected between terminals 11 and 13 of one of them. The low voltage terminals 21 and 22 are provided on the side surface of the molded coil 3, and their connection structure is as shown in FIG.

列に接続される。 An embodiment of the present invention will be described below with reference to FIGS. 4 and 5. 3A and 3B are two molded coils that are molded using a common transport mold and are placed side by side.Molded coil 3A is formed by molding synthetic resin onto high voltage coil 1A and low voltage coil 2A, and molded coil 3B is formed by molding synthetic resin with high voltage coil 1A and low voltage coil 2A. The coil 1B and low voltage coil 2B are molded with synthetic resin. A common iron core 31 is incorporated into the molded coils 3A and 3B arranged in parallel through the center through hole 4 thereof. Further, the molded coil 3A has high voltage terminals 11A, 12A and 13A, 14A provided spaced apart in a direction perpendicular to the juxtaposition direction on the opposite side and adjacent side of the upper surface thereof, and a fuse 6A is connected between the terminals 11A and 12. is attached, and terminals 11A and 14A are connected.
is internally connected to one end of the high voltage coil 1A, and the terminal 13A is internally connected to the other end of the high voltage coil 1A. Also, like the coil 3A, the molded coil 3B has high voltage terminals 11 provided on the opposite side and adjacent side of the upper surface of the molded coil 3B, spaced apart in a direction perpendicular to the direction in which they are arranged.
B, 12B and 13B, 14B, terminal 1
A fuse 6B is installed between 1B and 12B, and terminals 11B and 13B are connected to one end of the high voltage coil 1B.
The terminals 14B are internally connected to the other ends of the high voltage coil 1B, respectively, and the adjacent terminals 13A, 13B and 14
The high voltage coils 1A and 1B are connected in parallel by connecting the high voltage coils 1A and 14B on the outside with high voltage connecting wires 51 and 52, respectively. Terminals 21A and 22A of the low voltage coil 2A and terminals 21B and 22B of the low voltage coil 2B are arranged on one side of the molded coils 3A and 3B, respectively, and are connected in parallel on the outside by low voltage connecting wires 61 and 62.

鉄心を介し結合されるので資材量が少なく経済的
に製作できる。 With this configuration, the high-voltage coils can be connected in parallel by simply connecting the adjacent high-voltage terminals of the two molded coils arranged in parallel on the outside, so that the connecting wires that are connected in parallel as in the conventional method can be connected. This completely eliminates the drawback of complicated wiring due to long or crossed wires, and the structure is simple and can be housed in a small size. In addition, since the two molded coils are connected through a common iron core, the amount of materials used is small and it can be manufactured economically.
