Abstract
A dry-type capacitor sealing structure comprises an aluminium pot, an aluminium cover, a metal terminal and a rubber ring. The metal terminal is arranged on the top of the aluminium pot. The aluminium cover is on the aluminium pot. The metal terminal passes through the aluminium cover and the rubber ring and is arranged between the metal terminal and the aluminium cover. The aluminium cover is stamped on the aluminium pot, and the aluminium cover is in interference fit with the aluminium pot. According to the utility model, sealing performance of a dry-type capacitor can be effectively enhanced, and it is ensured that the metal terminal of the dry-type capacitor is insulated from the aluminium cover.
Description
Technical field
The utility model relates to a kind of hermetically-sealed construction, particularly relates to a kind of dry-type capacitor hermetically-sealed construction.
Background technology
Capacitor generally is divided into oil immersed type and dry power condenser.But oil immersed type is because polluting, large stability is not high will be eliminated gradually, take now dry-type capacitor as main, and it is mainly constructed by tank body, metallized polypropylene film coiling body, metal terminal etc. and forms.But its structure has a great difference, the different packaging structure of same components and parts also has a significant impact capacitor, existing dry-type capacitor only adopts one deck vinyl cover and aluminium pot to seal mostly, and the sealing that causes dry-type capacitor is poor, affects the useful life of dry-type capacitor.
Summary of the invention
The utility model purpose is to provide a kind of dry-type capacitor hermetically-sealed construction, and it can effectively strengthen the sealing property of dry-type capacitor, increases the service life, and guarantees that the metal terminal of dry-type capacitor and aluminium lid insulate mutually.
The utility model adopts following technical scheme:
A kind of dry-type capacitor hermetically-sealed construction, comprise aluminium pot, aluminium lid, metal terminal, rubber ring, metal terminal is arranged at described aluminium pot top, aluminium lid is on aluminium pot, metal terminal is through aluminium lid, rubber ring is located between metal terminal and aluminium lid, it is characterized in that: aluminium lid is stamped on aluminium pot and the two is interference fit.
Further, described rubber ring is T-shaped rubber ring.
The utility model beneficial effect compared with prior art is: safe and reliable, the dry-type capacitor sealing effectiveness is obvious, and the life-span is long.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of dry-type capacitor hermetically-sealed construction of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of dry-type capacitor hermetically-sealed construction, comprise aluminium pot (1), aluminium lid (2), metal terminal (3), rubber ring (4); Aluminium lid (2) is stamped into aluminium pot (1) above and the two is interference fit, seals; Metal terminal is arranged at the aluminium pot top, and metal terminal (3) is through aluminium lid (2), and rubber ring (4) is located between metal terminal (3) and aluminium lid (2), and rubber ring (4) plays the effect that aluminium lid (2) and metal terminal (3) are insulated mutually.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
