Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of sealing-in of Novel vacuum interrupter fixed ring
Structure, including porcelain shell 5, moved end sealing ring 3, the inside of the porcelain shell 5 are equipped with moving conductive rod 1, and one end of the moving conductive rod 1 is dynamic
The interior welds for passing through shaped solder ring 7 and fixed ring 6 outside sealing ring 3 are held, the outside of the moved end sealing ring 3, which is equipped with, to be fixed
The inside of ring 6, the fixed ring 6 is socketed with anti-torsion positioning mold 2, the moving conductive far from one end of the shaped solder ring 7
The outside of bar 1 is socketed with bellows 4 on one end of the shaped solder ring 7.
In specific implementation, the locating slot for cooperating fixed ring size is processed on movable end of vacuum arc extinguishing chamber sealing ring --- dress
Timing, using the stile positioning auxiliary of bellows 4,4 stile diameter of bellows is identical with 6 diameter of fixed ring, tolerance fit ripple
4 stile negative common difference of pipe, 6 oral area plus tolerance of fixed ring.
In specific implementation: the stile of the bellows 4 is higher than 6 bottom plane of fixed ring, and the stile of bellows 4 is low
In the anti-groove for turning round positioning mold 2, can be used to position.
In specific implementation: the moved end sealing ring 3 is identical as 6 diameter of bore of fixed ring, makes 4 stile of bellows can be with
Realize positioning requirements.
In specific implementation: the anti-torsion positioning mold 2 is fixed with the fixed ring 6 using gravity compacting.It may be implemented pair
The sealing-in of fixed ring 6.
Specifically, in use, sealing-in mode requires: 1, fixed ring 6 and 3 spot welding building block of moved end sealing ring-spot welding
