Abstract
An insulation sleeve effectively preventing electrical breakdown generated between film capacitor pole-shells belongs to the technical field of capacitors, and the insulation sleeve comprises a sealed aluminium case, an upper positioning sleeve, a lower positioning sleeve, and an explosion-proof cover plate, the upper positioning sleeve and the lower positioning sleeve are arranged in the aluminium case, the upper positioning sleeve and the lower positioning sleeve are combined in a sleeve shape, a top of the upper positioning sleeve is provided with the explosion-proof cover plate, a positioning column is arranged below the upper positioning sleeve, and the positioning column inserts a core rod. The upper and lower positioning sleeve with specific requirements are arranged inside the sealed aluminium case, and a capacitor core and the capacitor case are completed isolated by the upper and lower positioning sleeve with the specific requirements; the positioning column below the upper positioning sleeve inserts the core rod to fix the core, and very good positioning effect is reached; and the insulation sleeve of the utility model can completely replace existing and normal positioning sleeves, problem of massive waste products caused by electrical breakdown between the pole-shells in products testing is greatly reduced, and obviously reducing effect of making cost of capacitors is obtained.
Description
Technical field
The utility model relates to the capacitor technology field, is specifically related to a kind of insulating case that effectively prevents from occuring between the film capacitor utmost point shell electrical breakdown.
Background technology
Existing film capacitor comprises an aluminium shell and cover plate, up and down positioning sleeve is installed in the aluminium shell inside of sealing mouth, comprise up and down thin-film capacitor core and impregnating agent between the positioning sleeve, upper positioning sleeve top is the cover plate with explosion-proof block, lead-out wire on the capacitor body passes positioning sleeve and is connected with explosion-proof block base copper paillon foil, in the middle of the structure of whole capacitor, positioning sleeve plays insulation and the positioning action between fuse and the aluminum capacitor case up and down.
But upper and lower positioning sleeve has certain defective to the insulating effect of product in the existing product, thereby the qualification rate when having dragged down capacitor fabrication causes a certain amount of loss for capacitor manufacturing enterprise.The semi-finished product fuse of winding is after metal spraying, surface treatment procedure, about the peripheral residual a certain amount of width 1mm of two end faces of fuse, the metal spraying ash that is uneven in length, the shock effect that these residual metal spraying ashes are produced by external force in the operation processes such as fuse assembling, sealing comes off, and causes fuse and shell to be short-circuited in the test process that dispatches from the factory to cause that utmost point shell is withstand voltage can not to be passed through.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of low cost, can effectively prevents between the film capacitor utmost point shell electrical breakdown occuring the alternating current motor of improving product technical performance film capacitor insulating case.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of insulating case that effectively prevents from occuring between the film capacitor utmost point shell electrical breakdown, comprise aluminium shell, upper positioning sleeve, lower positioning sleeve and the explosion-proof covering board of sealing mouth, positioning sleeve and lower positioning sleeve are installed in the described aluminium shell, described upper positioning sleeve top is provided with explosion-proof covering board, the below is provided with reference column, and described reference column is inserted in the plug.
Described upper positioning sleeve and lower positioning sleeve are combined into sleeve-shaped.
The beneficial effects of the utility model are: the up and down positioning sleeve of special requirement is installed in the aluminium shell inside of sealing mouth, and by means of the up and down positioning sleeve of this special requirement, capacitor body and capacitor case are completely cut off fully to come; And the reference column of upper positioning sleeve below inserts plug, and fixedly fuse reaches good locating effect.The utility model can substitute existing conventional positioning sleeve fully, because occuring to puncture the problem that causes a large amount of waste products between the utmost point shell, also the capacitor manufacturing cost is had significant reducing effect when greatly reducing product test.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: the 1-aluminium shell; The upper positioning sleeve of 2-; Positioning sleeve under the 3-; The 4-explosion-proof covering board; The 5-reference column; The 6-plug.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of insulating case that effectively prevents from occuring between the film capacitor utmost point shell electrical breakdown, comprise aluminium shell 1, upper positioning sleeve 2, lower positioning sleeve 3 and the explosion-proof covering board 4 of sealing mouth, positioning sleeve 2 and lower positioning sleeve 3 are installed in the aluminium shell 1, upper positioning sleeve 2 is combined into sleeve-shaped with lower positioning sleeve 3, upper positioning sleeve 2 tops are provided with explosion-proof covering board 4, the below is provided with reference column 5, and reference column 5 is inserted in the plug 6.The fuse lead-in wire is drawn by upper positioning sleeve 2 edge groove parts, and this structure reaches good insulation effect so that capacitor body is complete and aluminium shell 1 is isolated; The reference column 5 of upper positioning sleeve 2 belows inserts plug 6, and fixedly fuse reaches good locating effect.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
