Abstract
The present utility model discloses an insulation shell body of a capacitor. The shell body comprises an aluminum cylindrical shell and a plastic cover plate, the aluminum cylindrical shell is molded with the plastic cover plate to form an integrated structure, a positioning column is arranged on the middle of the inner bottom surface of the aluminum cylindrical shell, the inner bottom surface of the aluminum cylindrical shell is also provided with a plurality of horizontal bosses, the horizontal bosses are uniformly arranged around the positioning column, and an insulation diaphragm is wrapped on the outer wall of the aluminum cylindrical shell. The shell body is simple in design, the shell cover is plastic and is not conductive, the positioning column and the bosses are arranged inside the shell body, capacitor elements can be prevented from being directly contacted with the shell body, and safety is increased.
Description
Technical field
The utility model relates to the shell of capacitor, mainly is a kind of insulation shell of capacitor.
Background technology
The shell of capacitor must guarantee insulation, prevents because of the effect of leakage personal safety, and the housing of existing capacitor and cap mainly all are to adopt aluminum material; The two conducts electricity easily; To draw wiring on the cap simultaneously, not notice during operation and will be arrived that insulation effect is poor by electricity.
The utility model content
The utility model technical problem to be solved provides a kind of insulation shell of capacitor, and its simplicity of design changes cap into plastic material; There is not conductivity; And be provided with reference column and boss in the housing, avoided capacitor element to contact, increased fail safe with the direct of housing.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of insulation shell of capacitor; Include the aluminum cylindrical shell, plastic cover plate, described aluminum cylindrical shell and the plastic cover plate injection mo(u)lding structure that fuses; Be provided with reference column in the middle of the said aluminum cylindrical shell inner bottom surface; Aluminum cylindrical shell inner bottom surface also is provided with a plurality of horizontal ledge, and described a plurality of horizontal ledge are evenly arranged around guide pile one circle, are coated with one deck insulation diaphragm on the outer wall of said aluminum cylindrical shell.
Have manyly to wire hole on the described plastic cover plate, in the wire hole position bursting diaphragm is installed on the inwall of plastic cover plate, there is perforate the corresponding wire hole of bursting diaphragm position.
The utility model has the advantages that:
The utility model simplicity of design changes cap into plastic material, does not have conductivity, and is provided with reference column and boss in the housing, has avoided the capacitor element to contact with the direct of housing, has increased fail safe, and insulation effect is good.
Description of drawings
Fig. 1 is the structural representation of the utility model.
