In addition, the coupling part 120 protrudes in the normal direction of the surface 113 of the winding part 110 at both ends of the winding part 110 so that the coil wound around the winding part 110 is around (high voltage part side). It is configured to include a protrusion 121 for limiting not to deviate, and the receiving receiving slot 122 for receiving the combination of the high pressure portion (200, 200 ').

Meanwhile, the high pressure parts 200 and 200 ′ have a rectangular pillar shape in which core insertion holes 212 having the same size as the winding part 110 of the low pressure part 100 are formed, and coils are wound around the outer surface 223. One end of the winding part 210 is formed while a winding protrusion 210 and a coupling protrusion rail 222 (coupling protrusion means for coupling), which are slidably inserted into the coupling receiving slot 122 of the coupling portion 120, are formed. That is, the coupling part 220 formed at an end opposite to the coupling part 120, the connection terminal 230 for connection to a power source or a load, and protrude in the normal direction of the surface of the winding part 210 are wound. It consists of a partition 240 that partitions the outer surface 223 of the portion 210 at predetermined intervals.
