A kind of capacitance shell, comprise housing, the center of the upper surface of described housing bottom is provided with the muscle one of annular, and the both sides, front and back of the muscle one of described housing bottom upper surface are respectively equipped with muscle two and muscle three, and the left and right sides of the muscle one of described housing bottom upper surface is respectively equipped with muscle four and muscle five; The bottom level of described hull outside wall is provided with claw, and the bottom lower surface of described housing is connected with screw rod;

The bottom of described housing is provided with mounting panel, described mounting panel is cuboid structure, the upper surface of described mounting panel has the groove suitable with described housing bottom shape, in the sidewall of described groove, be provided with the draw-in groove suitable with described claw, the center of described groove has the counterbore suitable with described screw rod, described counterbore greatly upside down, the edge between the upper and lower surface of described mounting panel has through hole.

Preferably, described muscle two is parallel to each other with muscle three, and is rectangular strip structure.

Preferably, described muscle four is located along the same line with muscle five, and is rectangular strip structure.

Preferably, the top of described draw-in groove is provided with back-off.

Preferably, described claw is provided with four, and it is located at respectively the center at described hull outside wall four sides; Described draw-in groove is provided with four, and it is suitable with described four claws respectively.

Preferably, described through hole is provided with four, and it is located at respectively the inner side in described mounting panel upper surface four bights.

By technique scheme, a kind of capacitance shell the utility model proposes, by muscle one, muscle two, muscle three, muscle four and muscle five are set, makes capacitance inner core can better be fixed in electric capacity housing; By mounting panel is set, make the heavier capacitor of weight become easily fastening.
