Description
Technical field
The utility model relates to high voltage switchgear manufacturing technology field, be specifically related to a kind of can directly and the sealing ring of crunch seal.
Background technology:
In vacuum interrupter, travelling wave tube speed, adjust in the electron tube productions such as pipe, need the technique of a large amount of employing ceramic and metal jointing and corresponding parts, the main material of usual ceramic and metal jointing determines expansion sealing-in teleoseal (be commonly called as and can cut down) with ceramic expansion coefficient similar, as trade mark 4J33,4J34 can cut down.Sealing ring part after processing not only will electroplate one deck nickel, also in hydrogen furnace, will could carry out soldering sealing-in after high-temperature process with pottery etc., and teleoseal is expensive.
Although stainless steel sealed ring is used widely in vacuum interrupter is produced in recent years, between pottery and stainless steel sealed ring, all add the oxygen-free copper transition part of a thickness 0.5 ~ 2mm, to reduce stress of sealing.So not only increase an oxygen-free copper part, also need multiplex a slice silver-copper brazing alloy, add a sealing weld more, have impact on rate of finished products.
Utility model content
The purpose of this utility model be to provide a kind of can directly and the sealing ring of crunch seal, to solve the above-mentioned multinomial defect caused in prior art.
A kind of can directly and the sealing ring of crunch seal, comprise sealing ring, ceramic cartridge and solder sheet, described sealing ring is tubbiness sealing ring, the bottom of sealing ring is connected with convex shoulder, be provided with arc transition band between convex shoulder and sealing ring, the bottom of sealing ring is connected with inner ring, and the outer wall of inner ring is together with the inwall welded seal of sealing ring, welded together by solder sheet between the bottom surface of inner ring and ceramic cartridge, described solder sheet has drawn from silver-bearing copper nickel solder.
Preferably, the external diameter bottom described inner ring is greater than the external diameter bottom sealing ring.
Preferably, the bottom surface of described inner ring is provided with several concentric annular grooves.
Preferably, the degree of depth of described annular groove is 0.5-1.5mm.
Preferably, the bottom surface of described sealing ring and inner ring are close together.
The utility model has the advantage of: this kind of sealing ring, structure is simple, easy to use, by increasing an inner ring, make this kind of sealing ring can adapt to the ceramic cartridge of different-diameter size, only need use different inner ring instead, saved cost, and inner ring is connected with sealing ring closely, good airproof performance, sound construction, described annular groove is conducive to fully to contact with inner ring after solder melts, and improve the fastness of connection, bottom surface and the inner ring of described sealing ring are close together, serve the effect supporting inner ring, inner ring is not fragile.
Accompanying drawing explanation
Fig. 1 be described in the utility model a kind of can directly and the structural representation of the sealing ring of crunch seal.
Fig. 2 be described in the utility model a kind of can the upward view of inner ring directly and in the sealing ring of crunch seal.
Wherein: 1-sealing ring, 2-ceramic cartridge, 3-solder sheet, 4-convex shoulder, 5-arc transition band, 6-inner ring, 7-annular groove.
