description The utility model discloses a metal-shell crystal vacuum encapsulation apparatus, which is composed of parts such as an upper electrode, a lower electrode, a vacuum box, a high and a low vacuum valves, a deflation valve, a vacuum valve, a vacuum gauge connection pipe, a dynamic seal ring, etc. The encapsulation of a welded crystal under the vacuum state can be realized. Consequently, the goal of improving long term frequency stability of the crystal can be achieved. Moreover, the utility model has the advantages of simple structure, easy fabrication, low cost, convenient operation, etc., and is an ideal encapsulation apparatus for improving frequency stability of the metal-shell crystal.
