Abstract
The utility model discloses a capacitor housing. The capacitor housing includes a cylindrical housing and a cover plate; an opening portion of the housing is provided with an enlargement portion whose diameter is greater than that of the housing, the bottom of the housing is provided with a protruding column, and protruding blocks are disposed at the periphery of the protruding column; and the edge of the cover plate is provided with flanges bending downwards, an annular protruding strip is disposed at the lower surface of the cover plate close to the edges, and the cover plate is provided with a through hole. The capacitor housing can be mounted firmly and safely, a problem that a capacitor needs a small capacity and a big opening is solved, and materials are saved, the sealing effect is good, and the service life is long.
Description
Technical field
The utility model relates to a kind of capacitor, particularly a kind of capacitor case.
Background technology
The shell great majority of the capacitor on market are cylindrical shape, structure is single can not meet diversified needs, sometimes need bore large, but volume requirement is below little, so can only increase the volume of shell integral body, cause waste, capacitor comprises shell and capacitor core, existing capacitor core is all to be coordinated and be arranged in capacitor case by cutting ferrule, install inner core is easily rocked in the enclosure like this, not fastening, once cutting ferrule is loose, just affected the work of whole capacitor, and when existing cover plate is connected with capacitor casing, sealing effectiveness is bad, after using a period of time, easily there is the phenomenon that cover plate and housing come off in capacitor, cause capacitor to lose efficacy.
Summary of the invention
The purpose of this utility model is just to provide a kind of sound construction, saves material, good sealing effect, the capacitor case of long service life.
To achieve these goals, the technical solution adopted in the utility model is such: capacitor case of the present utility model, comprise columnar housing and cover plate, the peristome of described housing is provided with expansion section, and the diameter of expansion section is greater than the diameter of housing, and the inner bottom part of housing is provided with projection, projection surrounding is provided with projection, the edge of described cover plate is provided with the flange of downward bending, and cover plate lower surface is provided with annular raised line near edge, is provided with through hole on cover plate.
As preferably, described projection is truncated cone-shaped, and its upper diameter is less than lower diameter.
As preferably, one end of described projection is towards the center of housing bottom, and projection is inclined-plane near the end face of projection.
Compared with prior art, the utility model has the advantage of: the peristome at housing arranges expansion section, the capacity that has solved capacitor needs little, but the necessary large problem of opening, and saving material, housing bottom arranges projection and projection, makes capacitor core and projection and bump contact, make to install fastening and safety, cover plate edge arranges flange and raised line, has increased the contact area of cover plate and housing, makes bonding more firm between cover plate and housing, through hole is set on cover plate, facilitates the installation of explosion-proof plug.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, capacitor case of the present utility model, comprise columnar housing 1 and cover plate 3, the peristome of described housing 1 is provided with expansion section 2, the diameter of expansion section 2 is greater than the diameter of housing 1, the inner bottom part of housing 1 is provided with projection 4, projection 4 surroundings are provided with projection 5, the edge of described cover plate 3 is provided with the flange 6 of downward bending, cover plate 3 lower surfaces are provided with annular raised line 8 near edge, on cover plate 3, be provided with through hole 7, described projection 4 is truncated cone-shaped, its upper diameter is less than lower diameter, one end of described projection 5 is towards the center of housing 1 bottom, projection 5 is inclined-plane near the end face of projection 4.
Peristome at housing 1 arranges expansion section 2, the capacity that has solved capacitor need to be little, but the necessary large problem of opening, and save material, housing 1 bottom arranges projection 4 and projection 5, capacitor core is contacted with projection 5 with projection 4, make to install fastening and safety, cover plate 3 edges arrange flange 6 and raised line 8, increased the contact area of cover plate 3 with housing 1, make bonding more firm between cover plate 3 and housing 1, through hole 7 is set on cover plate 3, facilitate the installation of explosion-proof plug.
Claims (3)
1. a capacitor case, comprise columnar housing and cover plate, it is characterized in that: the peristome of described housing is provided with expansion section, the diameter of expansion section is greater than the diameter of housing, the inner bottom part of housing is provided with projection, and projection surrounding is provided with projection, and the edge of described cover plate is provided with the flange of downward bending, cover plate lower surface is provided with annular raised line near edge, is provided with through hole on cover plate.
2. capacitor case according to claim 1, is characterized in that: described projection is truncated cone-shaped, and its upper diameter is less than lower diameter.
