<p>PURPOSE:To prevent the generation of crack due to the fastening force applied to an epoxy resin member, and to improve the reliability of airtight fitting by forming an end surface, on which a casing of a gas-blast load-break switch abuts, at a part of the epoxy resin member facing to a flange. CONSTITUTION:An epoxy resin member 2, of which cylindrical part 2a is formed in the periphery of a cylindrical part 1a of a terminal 1, is molded integrally with the periphery of the bar-like terminal 1 so as to expose a plate part 1b of the terminal 1, and a flange 2b projecting in the radial direction is formed integrally with the periphery of the epoxy resin member 2. An epoxy resin mold bushing having such a structure is fitted airtight through a packing 5 by inserting the busing into a through hole of a casing 4 of a gas-blast load- break switch from outside so that the flange 2b abuts on the outer surface of the casing 4 through the packing 5, and fastening the flange 2b with a male screw 8 from the inside of the casing 4 so that the flange 2b is fastened forcedly to the outer surface of the casing 4.</p> |
