PURPOSE:To form a leading structure which can resist against high temperature and high pressure by integrally molding leading wirings with an insulating ring and a metal sealing ring, and pressing the flange of the lead of a frame through an O-ring by cooling hydraulic liquid. CONSTITUTION:The bare conductor 13a of an insulated wire 13 is soldered to the recess of a conductor 9 which has a collar 9a passing through a lead wiring hole of a frame 2. Then, the conductor 9, an insulating ring 11 made of epoxy resin or the like and a metal sealing ring 10 having an O-ring groove are integrally molded with rubber, plastic insulating film 12 in a mold, not shown, thereby forming an insulated conductor 14. O-rings 10a, 10b are inserted between a frame 2 and a metal sealing ring 10. The bare part 9b of the conductor 9 is led out of the frame 2, a nut 16 is screwed at 9c by holding an insulating support 15, and the conductor 9 is secured to the frame 2. High pressure of cooling sealing liquid 3 is acted to aid the effect of the O-ring 10b. In this manner, the seal which resists against high pressure and high temperature can be formed. |
