Described case covers on pedestal, forms annular groove between the tegmental wall of case and the flange of pedestal, and "O"-ring is located in annular groove；
Described A inserted sheet, the rectangular washer of B inserted sheet form rectangle annular groove with the rectangular channel periphery of pedestal respectively；In rectangle annular groove in fluid sealant embedding annular groove between tegmental wall and flange and between rectangular washer and rectangular channel；Described fluid sealant uses epoxy resin, and the technique using embedding, room temperature or heating cure.
The present invention uses and arranges annular groove between case and pedestal, rectangle annular groove is set between inserted sheet and pedestal, by the way of "O"-ring and fluid sealant embedding are set so that the position that pedestal contacts with external environment is effectively sealed, and has simple in construction, volume is little, easy to assembly, production cost is low, good seal performance, antirust, anti-corrosive ability is strong, the advantage that functional reliability is high.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 is that the A of Fig. 1 is to partial view.
Detailed description of the invention:
Refering to Fig. 1, Fig. 2, the present invention includes bimetal leaf 2, location dish 3, moving contacting plate 6, quiet contact chip 12 and push rod 15, it also includes case 1, pedestal 4, A inserted sheet 8, B inserted sheet 9, "O"-ring 14 and fluid sealant 16, described case 1 is the circular lid being provided with tegmental wall 11, what pedestal 4 set cavity in being has end cylinder, cylindrical top is provided with the flange 41 turned up, bottom surface is provided with the rectangular channel 42 of two depressions, being provided with through hole 43 between rectangular channel 42 and cavity, A inserted sheet 8, B inserted sheet 9 are provided with the metallic conduction sheet of rectangular washer 91 for one end；
Described push rod 15, location dish 3 and bimetal leaf 2 are sequentially arranged in the cavity of pedestal 4, moving contacting plate 6, quiet contact chip 12 are respectively arranged on the cavity end of pedestal 4 through hole 43, A inserted sheet 8, the rectangular washer 91 of B inserted sheet 9 are respectively arranged on rectangular channel 42 end of pedestal 4 through hole 43, and rivet is riveted respectively through through hole 43；
Described case 1 covers on pedestal 4, forms annular groove 111 between the tegmental wall 11 of case 1 and the flange 41 of pedestal 4, and "O"-ring 14 is located in annular groove 111；
Described A inserted sheet 8, the rectangular washer 91 of B inserted sheet 9 form rectangle annular groove 112 with rectangular channel 42 periphery of pedestal 4 respectively；In rectangle annular groove 112 in fluid sealant 16 embedding annular groove 111 between tegmental wall 11 and flange 41 and between rectangular washer 91 and rectangular channel 42；
