Abstract
The utility model relates to a locating sealing ring for a vacuum arc-extinguishing chamber, which is a brazing locating device for the vacuum arc-extinguishing chamber and is mainly to solve the problems of low production efficiency, poor locating precision, unreliability, low yield, difficulty in guarantee of quality, incapability in adaptation to the requirements of batch production of a traditional vacuum arc-extinguishing chamber. The locating sealing ring for the vacuum arc-extinguishing chamber consists of a dynamic and static end cover, a sealing ring, a solder sheet and a porcelain cylinder and is mainly characterized in that the dynamic and static end cover and the sealing ring are located through inner and outer steps, and the locating between the porcelain cylinder and the solder sheet is guaranteed by the sealing ring, so that the locating between the porcelain cylinder and the solder sheet, the sealing ring and the dynamic and static end cover is accurately and effectively guaranteed. The locating sealing ring is simpler in operation and more accurate and reliable in locating, the production efficiencyis greatly improved, and the requirements of batch production of the vacuum arc-extinguishing chamber are effectively guaranteed.
Description
Technical field
The utility model belongs to electron tube process structure design field, relates to a kind of soldered into position device of vacuum interrupter, is that a kind of vacuum interrupter that is specially adapted to improves yields, and production method is simpler, locate more reliably sealing ring.
Background technology
As everyone knows, the production of vacuum interrupter is to use soldering processes that porcelain cylinder, the sound end cap of unlike material are welded.Its structure is comprised of sound end cap, sealing ring, solder sheet, porcelain cylinder, and sound end cap and sealing ring are by inside and outside step location, and solder sheet can be crossed scolder and fasten on sealing ring, then observes the positioning accuracy that guarantees sealing ring and porcelain cylinder by the operative employee.The drawback of this structure is: vacuum interrupter production efficiency is low, positioning accuracy is poor and unreliable, and yields is lower, is difficult to ensure the quality of products.Therefore, the sealing ring of traditional vacuum interrupter can not adapt to the vacuum interrupter batch production, ensures the requirement of assembly precision, the situation that causes vacuum interrupter to be scrapped often can occur being partially welded.At present, need seek a kind of simpler, more reliable new method for producing, to reach the production purpose of simple to operate, easy control, precise and high efficiency.
Summary of the invention
The purpose of this utility model is exactly the existing problem and shortage part of sealing ring of now using for vacuum interrupter, and the location sealing ring of a kind of control simple to operate, easy, precise and high efficiency is provided, this sealing ring can guarantee the location between porcelain cylinder and sealing ring, the sound end cap accurately and effectively.
Technical solution of the present utility model is: a kind of vacuum interrupter improves production yields, the soldered into position position device of simpler, the easy control of production method, precise and high efficiency.New sealing ring positioner is comprised of sound end cap, sealing ring, solder sheet, porcelain cylinder, its principal character is: sound end cap and sealing ring are by the step location of sealing ring, sealing ring guarantees the location between porcelain cylinder and the solder sheet, thereby guarantees accurately and effectively the location between porcelain cylinder and solder sheet, sealing ring, the sound end cap.Operate simpler, the location more accurately and reliably, production efficiency improves greatly, has effectively guaranteed the needs of vacuum interrupter batch production.
The beneficial effects of the utility model are: operate simpler, the location more accurately and reliably, production efficiency improves greatly, reduces the use amount of scolder, has saved manufacturing cost, and has effectively guaranteed the needs of vacuum interrupter batch production.
