Abstract
The utility model discloses a power capacitor, which comprises a capacitor casing, a sealing ring and a binding post fixed on the capacitor casing. The binding post comprises a ceramic insulator. An annular positioning boss is arranged on the outer wall of the lower portion of the ceramic insulator. The capacitor casing is provided with a mounting sleeve. The sealing ring is sleeved on the outer wall of the insulator and arranged adjacently to the bottom wall of the annular positioning boss. The mounting sleeve comprises a pressing portion, a sleeving portion and an annular rolling portion. The pressing portion is used for pressing the sealing ring on the bottom wall of the annular positioning boss. The sleeving portion is sleeved on the outer circumferential wall of the annular positioning boss. The annular rolling portion is fastened with the top wall of the annular positioning boss in a rolling manner. The pressing portion is formed by rolling a pipe wall, and is in the shape of an annular boss with the V-shaped or U-shaped section inside a pipe and in the shape of an annular groove with the V-shaped or U-shaped section outside the pipe. The power capacitor has the advantages of few procedures 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, sealing ring and be fixed on the binding post on the capacitor casing; Said binding post comprises ceramic insulator, and said ceramic insulator bottom outer wall is provided with annular locating lug boss; Said capacitor casing is provided with mounting sleeve; Said sealing ring be set on the insulator outer wall and with the annular locating lug boss diapire in abutting connection with setting; Said mounting sleeve comprises and is used for being pressed on sealing ring compressed part on the annular locating lug boss diapire, being used to be set in the socket part on the annular locating lug boss periphery wall and snapping onto the roll extrusion ring portion on the annular locating lug boss roof through the roll extrusion mode; Said compressed part is to form through the roll extrusion tube wall, and it is the annular boss shape that cross sectional shape is V font or U font in the pipe inboard, and it is the annular groove shape that cross sectional shape is V font or U font in the pipe outside.
In the such scheme, said mounting sleeve and capacitor casing are integral pieces.
The utlity model has positive effect: in the power capacitor of (1) the utility model, directly punch forming goes out the mounting sleeve that fuses with capacitor casing on capacitor casing; Only need a roll extrusion; Also promptly only need snap onto mounting sleeve on the annular locating lug boss on the outer wall of insulator bottom through roll extrusion; Can be fixedly mounted on binding post on the capacitor casing, so the utility model product has less, the lower-cost advantage of operation.
