The invention has the advantages that:
1, capacitor of the present invention is owing to adopting all-metal material encapsulating structure, improves the fail safe (as fire prevention) in capacitor use procedure
Have at the bottom of the shell of 2, capacitor casing of the present invention and form for injection moulding the hole that installed part inserted soon by plastics, this hole is the blind hole that Open Side Down, extends to form installed part fixed card slot towards periphery at the bottom of the hole in this hole.Form plastics by this hole and installed part fixed card slot energy fast injection molding and insert installed part soon, insert by these plastics the quick grafting installation that installed part can realize capacitor soon.
3, use the present invention, plastics are inserted installed part soon and are formed by injection moulding, avoid plastics and insert the installed part trouble of manually installing soon, improve production efficiency.And, this hole be wear in a kind of limiting holes object around hole axle to rotate shape, avoid plastics soon insert installed part install after rotation phenomenon.
4, the present invention can make the structure of capacitor compacter, effectively reduces height and the volume of capacitor.
5, capacitor Aluminum cover of the present invention is compared with existing aluminum safety cap, and material usage reduces greatly, thus reduces the manufacturing cost of product.
