Description
Technical field
The utility model belongs to the structure-design technique field of power capacitor, is specifically related to a kind of power capacitor housing.
Background technology
Present power capacitor, still the binding posts of ceramic insulator that use as main body more, main cause is that most power capacitor is for fear of the internal liquid seepage, need the whole comparatively strict sealing property that has, in addition, because power capacitor is compared with other High-Voltage Electrical Appliances mostly, price is comparatively cheap, in order to keep competitiveness, also have to use low-cost pottery as the binding post main body.
Described binding post 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 binding post need be fixed on metal fixed mounting on the outer wall of insulator body when making assembling by welding manner; During installation, 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 the ceramic insulator with fixed mounting inserted in the mounting interface, and the mounting interface of fixed mounting on capacitor casing is weldingly fixed on scolder.
The binding post that this pottery is made is because parts are more, and assembling one by one, thus cause its processing technology loaded down with trivial details, and waste product appears easily; Well known fact is simultaneously: pottery dodges poor-performing than great, frangible and anti-soil; So the structure of this traditional binding post is still needed improvement badly.
In addition, adopt the shortcoming of the high-voltage power capacitor that this traditional ceramics binding post makes to be: when making power capacitor, need make described fixed mounting, on capacitor casing, stamp out two independent operations of mounting interface, when fixed mounting being installed on the ceramic insulator body, need once welding in addition, also need once to weld in the time of on the mounting interface that fixed mounting is fixed on capacitor, cause its manufacturing procedure more, complex operation and cost are higher.
The utility model content
The purpose of this utility model provides the power capacitor housing that a kind of cost is lower and have good seal performance.
Realize that a kind of technical scheme of the present utility model is: a kind of power capacitor housing, it is characterized in that: the shell wall of described power capacitor is provided with by the formed metal installation base that is used to install and fix external binding post of direct punching press shell wall, and described metal installation base comprises and is used for the Plastic Division of fixedlying connected with described insulator body and is used for fixing installation installation portion in the external appliance; The top of described Plastic Division protrudes upward the vestibule that described installation portion surrounds.
In the such scheme, the basic configuration of described metal installation base is a tubulose; Its tube wall is an installation portion, and described Plastic Division comprises the male member that is arranged on the installation portion inwall.
In the such scheme, the top of described male member is provided with extends vertically upward and exceeds the tubulose fixed part that described installation portion surrounds vestibule.
In the such scheme, the distal edge wall two side ends of described tubulose fixed part is provided with the blocking teeth that forms by the punch forming mode.
In the such scheme, described blocking teeth is arranged with being interspersed in the form of a ring.
The good effect that the utlity model has:
(1) in the utility model, described metal installation base is the male member that is molded directly within on the capacitor casing, external binding post and metal installation base can be by injection mo(u)lding or the compression molding parts that becomes one, also be that described binding post and power capacitor housing can be by injection mo(u)lding or the compression molding parts that becomes one, compare with traditional wired post and power capacitor, save many parts and assembling procedure, effectively reduced manufacturing cost; In addition and since by by with the Plastic Division plastic packaging of metal installation base on insulator body, its sealing property also is guaranteed.This kind power capacitor no longer needs to process independent fixed mounting during fabrication, but the male member that directly punch forming and capacitor casing fuse on capacitor casing, so also no longer need to stamp out the operation of mounting interface; In addition, only need a plastic packaging, also promptly only need can be fixedly mounted on the fixed mounting plastic packaging on the capacitor casing to binding post on the insulator body, also no longer need traditional welding sequence, so the utility model product has the advantage that excellent sealing performance is comparatively simplified and had to processing technology.
