Abstract
The utility model relates to a capacitor lower positioning sleeve produced by a waste electrical polypropylene film. The bottom of the lower positioning sleeve is a circular chassis. A plurality of upwardly-protruded reinforcement ribs are disposed on the top of the chassis. An annular wall in cooperation with the inner wall of the housing of a capacitor is arranged on the periphery of the chassis. The lower positioning sleeve is produced by a waste electrical polypropylene film. An upwardly-protruded circular positioning column is arranged on the center of the chassis. The external diameter of the positioning columns is not more than the internal diameter of a mandrel through hole on the center of a capacitor core set. A side-directional opening groove in which an insulated wire connected with the metal spraying surface of the capacitor core set is disposed on the sidewall of the positioning column. The capacitor core set can be accurately positioned in the center of the housing, and achieves a good insulating property, increases qualified rate of capacitor products by 20 percent, and achieves high quality consistency.
Description
Technical field
The utility model relates to positioning sleeve under a kind of capacitor, positioning sleeve under the capacitor that specifically the useless electrician's polypropylene film of a kind of use is produced.
Background technology
Alternating current motor generally adopts cylindrical capacitor core group with metalizing polypropylene thin film capacitor, and this core group is vertical placement in the enclosure, and its upper end is typically provided with lower positioning sleeve, to prevent that capacitor core group from rolling.This lower positioning sleeve bottom is circular base plate, and upper end, chassis is provided with several reinforcements that raise up to gain in strength, and chassis surrounding has the annular wall coordinating with capacitor case inwall.Such as, provided to Anhui Tongfeng Electronic Co. Ltd. by applicant, be exactly so a kind of structure for the production of the lower positioning sleeve of CBB65 type capacitor.Capacitor is in the time of assembling, due to gapped between capacitor core group and the annular wall of lower positioning sleeve surrounding, inevitably there is in the enclosure the inclination of certain angle in capacitor core group, interval between metal spraying face and shell is reduced, cause capacitor the two poles of the earth to shell decreasing insulating, thereby the qualification rate of capacitor product is declined.
Summary of the invention
The purpose of this utility model is to provide positioning sleeve under the capacitor that the useless electrician's polypropylene film of a kind of use produces, and can accurately locate capacitor core group, improves capacitor product qualification rate.
The utility model is achieved in that described lower positioning sleeve bottom is circular base plate, upper end, chassis is provided with several reinforcements that raise up, chassis surrounding has the annular wall coordinating with capacitor case inwall, described lower positioning sleeve is made with useless electrician's polypropylene film, in the middle of chassis, be provided with the reference column of projection upward, the external diameter of reference column is not more than the internal diameter of the middle plug through hole of capacitor core group, and reference column sidewall is provided with the lateral openings groove passing through for the insulated conductor that connects capacitor core group metal spraying face.
In the time that capacitor is assembled, first the lateral openings groove of lower positioning sleeve reference column is aimed to the insulated conductor of the connection capacitor core group metal spraying face in plug intermediate throughholes, again reference column is embedded completely in the middle through hole of plug, thereby core group is positioned in the middle of lower positioning sleeve between two parties.Because the annular wall of lower positioning sleeve surrounding is mated with shell inner cavity, thereby core group is accurately positioned at the centre of shell, makes between metal spraying face and shell interval even, and insulation property improve, thereby can improve the qualification rate of capacitor product.
Above-mentioned reference column suitable length is 8～12mm, can ensure that reference column has sufficient length to embed in plug intermediate throughholes, makes plug can not depart from lower positioning sleeve.
In order to facilitate insulated conductor to enter the lateral openings groove on reference column sidewall, the lateral openings well width that a preferred version of the present utility model is reference column expands flare shape gradually to openend.
The utility model by arranging the reference column embedding in plug in the middle of lower positioning sleeve, and core group can accurately be positioned at the centre of shell, good insulation preformance, and the qualification rate of capacitor product can improve 20%, and quality conformance is high.In addition, lower positioning sleeve is made with useless electrician's polypropylene film, can recycle useless electrician's polypropylene film material, cost-saving.

Fig. 2 is the vertical view of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, under the utility model, positioning sleeve is made with useless electrician's polypropylene film.Lower positioning sleeve bottom is circular base plate 2,2 upper ends, chassis are provided with several reinforcements that raise up 3, chassis 2 surroundings have the annular wall 1 coordinating with capacitor case inwall, in the middle of 2 upper ends, chassis, be provided with the reference column 4 of projection upward, the external diameter of reference column 4 is not more than the internal diameter of the middle plug through hole of capacitor core group, reference column 4 in the time of assembling is easily embedded in the middle through hole of plug, and reference column 4 upper ends are provided with outer conical surface 5, and during with ease of assembly, reference column 4 embeds in the middle through hole of plug.Reference column 4 sidewalls are provided with the lateral openings groove 6 passing through for the insulated conductor that connects capacitor core group metal spraying face.
Consider that reference column 4 has sufficient length to embed in the through hole of plug, make capacitor core group can not depart from lower positioning sleeve, reference column 4 length are that 8～12mm is more suitable.
In order to facilitate insulated conductor to enter the lateral openings groove 6 on reference column 4 sidewalls, the width of lateral openings groove 6 expands flare shape gradually to openend.
Above-mentioned reference column 4 passes through Shooting Technique global formation with lower positioning sleeve body.
