The invention discloses a power capacitor, comprising a capacitor shell and a terminal fixed on the capacitor shell. The terminal comprises a ceramic insulator and a metal connecting piece fixed on the outer wall of the lower part of the ceramic insulator; the outer wall of the lower part of the ceramic insulator is provided with an annular positioning boss; the capacitor shell is provided with a mounting base; the metal connecting piece is fixed on the mounting base in a welding manner; and the metal connecting piece is fixed on the annular positioning boss in a rolling manner. According to the power capacitor, the mounting base integrally connected with the capacitor shell can be punched and molded on the capacitor shell by welding for one time; and namely, the terminal can be fixedly mounted on the capacitor shell by welding the metal connecting piece arranged on the ceramic insulator on the mounting base. Therefore, the power capacitor has the advantages of less procedures and low cost.
Description
Technical field
The present invention relates to ceramic-type binding post structure design field, relate in particular to a kind of ceramic insulator for power capacitor.
Background technology
Existing high-voltage power capacitor comprises capacitor casing and is arranged on the ceramic insulator device on electric capacity housing; Described each ceramic insulator device comprises ceramic insulator body, be welded on the connector assembly at insulator top, be weldingly fixed on the fixed mounting of insulator bottom.This kind of ceramic insulator device, in the time manufacturing assembling, need to be fixed on metal fixed mounting on the outer wall of insulator body by welding manner; This kind of ceramic insulator device when mounted, first need on the metal shell of capacitor, stamp out the mounting interface of the tubulose matching with fixed mounting shape, and then the ceramic insulator with fixed mounting is inserted in mounting interface, and together with fixed mounting being welded and fixed with the mounting interface in capacitor casing with scolder.
The shortcoming of this traditional high-voltage power capacitor is: in the time making power capacitor, need to make described fixed mounting, in capacitor casing, stamp out two independent operations of mounting interface, in the time fixed mounting being installed on ceramic insulator body, need to once weld in addition, on the mounting interface that fixed mounting is fixed on to capacitor time, also need once to weld, cause its manufacturing procedure more, complex operation and cost are higher.
Summary of the invention
The object of this invention is to provide the power capacitor that a kind of manufacturing procedure is less, manufacturing cost is lower.
The technical scheme that realizes the object of the invention is: a kind of power capacitor, comprise capacitor casing and be fixed on the binding post in capacitor casing, described binding post comprises ceramic insulator and be fixed on the metal connecting piece on the outer wall of ceramic insulator bottom, and described ceramic insulator bottom outer wall is provided with annular locating lug boss; Described capacitor casing is provided with mount pad, and described metal connecting piece is fixed on metal connecting piece by welding manner; Its design feature is: also comprise sealing ring, described sealing ring is set on the outer wall of ceramic insulator bottom and in abutting connection with the setting of annular locating lug boss diapire; Described ceramic insulator external wall of upper portion is provided with ring-type roll extrusion snapping boss, and middle part outer wall is provided with full skirt, and bottom outer wall is provided with annular locating lug boss, and its roof is provided with hexagonal groove, and ceramic insulator is also provided with along self central shaft to the through hole running through; Described metal connecting piece is fixed in this annular locating lug boss by roll extrusion mode; Described metal connecting piece comprises for sealing ring being pressed on to compressed part on annular locating lug boss diapire, being set in the socket part on annular locating lug boss periphery wall and snapping onto the roll extrusion portion on annular locating lug boss roof by roll extrusion mode; On described mount pad and metal connecting piece, be equipped with welding plane; Described connector assembly comprises and is arranged in the Gask-O-Seal of insulator roof groove, the bolt with nut and double-screw bolt and roll extrusion sleeve pipe; Described roll extrusion sleeve pipe comprise bolt upper cap nut be pressed on lid nip on Gask-O-Seal, for being set in the cannula portion on ring-type roll extrusion snapping boss periphery wall and snapping onto the snapping ring on ring-type roll extrusion snapping boss diapire by roll extrusion mode.
The present invention has positive effect: in (1) power capacitor of the present invention, directly in capacitor casing, punch forming goes out the mount pad being connected with capacitor casing; Only need to once weld, also only the metal connecting piece on ceramic insulator need to be welded on mount pad, binding post can be fixedly mounted in capacitor casing, so product of the present invention has less, the lower-cost advantage of operation.
