Abstract
The utility model discloses a metallized film capacitor which comprises a casing (1) and a capacitor core (2) positioned inside the casing (1). The metallized film capacitor is characterized in that a seal cover (3) is arranged at the upper end of the casing (1), an epoxy resin coating (4) is covered on the seal cover (3), the seal cover and the casing (1) together form a sealed body, castor oil (6) is injected between the capacitor core (2) and the casing (1) inside the sealed body, the lower part of a lead terminal (5) passes through the epoxy resin coating (4) and the seal cover (3) and is electrically connected with the capacitor core (2). The utility model has the advantages of low production cost and less environmental burden.
Description
Technical field
The utility model relates to capacitor, especially the sealing device of capacitor.
Background technology
Known its epoxy resin by housing, chipware, lead-in wire, embedding of metallic film capacitor that has leading-out end line is formed.This capacitor is widely used in the startup and the operation of the less relatively one-way motors of electrical power such as air conditioner, electric fan, ventilating fan.This capacitor system adopts thickened metalized polypropylene film in zinc-aluminium edge or net-like metallic safety polypropylene film through coiling, typing, operations such as end face metal spraying make the capacitor chipware, and an end of lead-out wire welded mutually with the two ends of chipware respectively, it is inserted in the housing, be fed into epoxy resin, treat that its curing makes existing product.There is following shortcoming in above-mentioned capacitor: 1. must remaining space in the housing all be filled with epoxy resin owing to this method, thereby it is too much to expend resin, because epoxy resin costs an arm and a leg, therefore increases the capacitor fabrication cost; 2. form owing to fire-retardant epoxy resin mainly is difficult for degradable material by some, thereby too much the meeting of use increases environmental burden.
The utility model content
The purpose of this utility model is exactly to solve the metallic film capacitor epoxy resin have leading-out end line to seal fuse, use the production cost height, the problem of increase environmental burden.
The technical solution adopted in the utility model is: a kind of metallic film capacitor, it comprises shell and is positioned at the capacitor body of shell, the upper end that it is characterized in that described shell is provided with capping, be coated with epoxy resin layer in the capping, constitute seal jointly with shell, between capacitor body in the seal and the shell is castor oil, and the leading-out terminal bottom passes epoxy resin layer and capping is electrically connected with capacitor body.
Adopt technique scheme, owing to use castor oil in the seal, and the price of castor oil is lower, therefore greatly reduces cost; Castor oil can not produce environment and pollute simultaneously, therefore can not bring pressure to environmental protection.

Fig. 1 is the utility model structural representation.
Among the figure, 1, shell, 2, capacitor body, 3, capping, 4, epoxy resin layer, 5, leading-out terminal, 6, castor oil.
Embodiment
A kind of metallic film capacitor of the utility model, as shown in Figure 1, it comprises shell 1 and the capacitor body 2 that is positioned at shell 1, and the upper end of described shell 1 is provided with capping 3, and the top of shell 1 is provided with the boss that cooperates with capping 3, and capping 3 is squeezed on the boss.Being coated with epoxy resin layer 4 in the capping 3, with shell 1 common formation seal, is castor oil 6 between capacitor body 2 in the seal and the shell 1, and leading-out terminal 5 bottoms pass epoxy resin layer 4 and capping 3 is electrically connected with capacitor body 2.
Claims (1)
