PURPOSE:To fix an electrode on a can body for sure with sufficient insulation and watertight state by inserting a corrosion-proof electrode with a bent into a socket of the can body for fixing by two porcelain insulators and sealing the bent part by adhesives between the two porcelain insulators. CONSTITUTION:A socket 4 is screwed and fixed to a fitting cylinder 3 shaped on a can body 1, and a porcelain insulator 7 with insulating adhesives applied on the surface is fitted into a staged fitting part 5 inside the socket 4. An electrode 8 with a bent part 8' is inserted into an electrode inserting hole 6 penetrated in the porcelain insulator 7, and the bent part 8' is sealed up in a sealing part 9 filled with adhesives. Then another porcelain insulator 10 with adhesives applied on the surface is fitted into the socket 4, and into its electrode inserting hole 11, the electrode 8 is penetrated in the rear end. A plug 12 is screwed into the rear end of the socket 4, and an electrode inserting hole 13 is filled with adhesives 14. |
