Abstract
The utility model discloses a power capacitor, comprising a capacitor housing and a binding post fixed on the capacitor housing. The binding post comprises a ceramic insulator and a metal connecting piece fixed on an outer wall of a lower part of the ceramic insulator. The outer wall of a lower part of the ceramic insulator is provided with an annular positioning boss. The capacitor housing is provided with a fitting seat. The metal connecting piece is fixed on the metal connecting piece through welding. The metal connecting piece is fixed on the annular positioning boss through rolling. In the power capacitor, the fitting seat is connected to form a whole with the capacitor housing through direct punch forming on the capacitor housing. The binding post can be fixedly installed on the capacitor housing just through once welding and welding the metal connecting piece of the ceramic insulator on the fitting seat. So the power capacitor is advantaged by relatively less process and low cost.
Description
Technical field
The utility model relates to ceramic-type binding post structure-design technique field, relates in particular to a kind of ceramic insulator that is used for power capacitor.
Background technology
Existing high-voltage power capacitor comprises capacitor casing and is arranged on the ceramic insulator device on the electric capacity housing; Said each ceramic insulator device comprises the ceramic insulator body, be welded on the connector assembly at insulator top, be weldingly fixed on the fixed mounting of insulator bottom.This kind ceramic insulator device need be fixed on metal fixed mounting on the outer wall of insulator body when making assembling through welding manner; This kind ceramic insulator device when mounted; Need on the metal shell of capacitor, stamp out the mounting interface of the tubulose that matches with the fixed mounting shape earlier; And then insert ceramic insulator in the mounting interface, and the mounting interface of fixed mounting on capacitor casing is weldingly fixed on scolder with fixed mounting.
The shortcoming of this traditional high-voltage power capacitor is: when processing power capacitor; Need process said fixed mounting; On capacitor casing, stamp out two independent operations of mounting interface, when being installed to fixed mounting on the ceramic insulator body, need once welding in addition, also need once welding in the time of on the mounting interface that is fixed on fixed mounting in capacitor; Cause its manufacturing procedure more, complex operation and cost are higher.
The utility model content
The purpose of the utility model provides the power capacitor that a kind of manufacturing procedure is less, manufacturing cost is lower.
The technical scheme that realizes the utility model purpose is: a kind of power capacitor; Comprise capacitor casing and be fixed on the binding post on the capacitor casing; Said binding post comprises ceramic insulator and is fixed on the metal connecting piece on the outer wall of ceramic insulator bottom that said ceramic insulator bottom outer wall is provided with annular locating lug boss; Said capacitor casing is provided with mount pad, and said metal connecting piece is fixed on the metal connecting piece through welding manner; Said metal connecting piece is fixed on this annular locating lug boss through the roll extrusion mode.
In the such scheme, also comprise sealing ring, said 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; Said metal connecting piece comprises and is used for sealing ring is pressed on compressed part on the annular locating lug boss diapire, is set in the socket part on the annular locating lug boss periphery wall and snaps onto the roll extrusion portion on the annular locating lug boss roof through the roll extrusion mode.
In the such scheme, be equipped with the welding plane on said mount pad and the metal connecting piece.
The utlity model has positive effect: in the power capacitor of (1) the utility model, directly punch forming goes out the mount pad that fuses with capacitor casing on capacitor casing; Only need once welding, also promptly only need be welded on the metal connecting piece on the ceramic insulator on the mount pad, can be fixedly mounted on binding post on the capacitor casing, so the utility model product has less, the lower-cost advantage of operation.
