Abstract
The utility model discloses a capacitor plastic shell, and belongs to the technical field of capacitors. The capacitor plastic shell comprises a shell and a core body. The internal wall of the shell is provided with first fixed ribs. The surfaces of the first fixed ribs are contacted with the core body. There are at least two first fixed ribs. The internal side of the bottom part of the shell is provided with second fixed ribs. Three first fixed ribs are symmetrically arranged relative to the center of the circle of the core body. The upper surface of each first fixed rib has an internal concave arc shape. The core body can be greatly centered and positioned by the first and second fixed ribs, and material pouring for sealing of the core body is more uniform with complete encapsulation. Besides, the structure is simple, operation is easy and cost is low.
Description
Technical field
The utility model relates to a kind of capacitor, is specifically related to a kind of plastic capacitor shell.
Background technology
Capacitor is one of a large amount of electronic components that use in electronic equipment, is widely used in every aspects such as straight, coupling, bypass, filtering, resonant tank, power conversion, control circuits.
Plastic casing is to be widely used in manufacturing in various capacitors, owing to adopting the capacitor of plastic casing mostly to adopt epoxy resin perfusion capacitor core body.Reliable and stable for ensureing capacitor, its core body should obtain as far as possible relatively evenly epoxy layer around and cover, and must ensure the center of electric capacity core body at shell diameter.
In Chinese Patent Application No.: disclose a kind of capacitor in 200620077218, it includes shell, core body, it is characterized in that: be provided with the strong point on the inner surface of shell.By the strong point is set, position to core body and angle are fixed well, simultaneously because the existence of the strong point, make the inner bottom surface of core body and shell have a free space, in whole filling process, sealing fluid or consolidation liquid can fully fill up this free space, avoid the generation of bubble, made production engineering easy, be conducive to improve the production efficiency of product.But this technical scheme can not be fixed between two parties to core body, can not seal core body completely, locating effect is undesirable.
In Chinese Patent Application No.: disclose a kind of engineering plastic housing capacitor in 200920172331, include slot type housing, core body, weld tabs, slot type housing intracavity bottom has positioning bar, described slot type inner walls weld tabs installation place has location notch, described weld tabs outside is connected with elasticity angle, and described elasticity angle supports in described location notch, and described core body, weld tabs are cured as one by epoxy resin and slot type housing inner chamber.This technical scheme can not be fixed between two parties to core body, can not seal core body completely, and locating effect is undesirable.
In Chinese Patent Application No.: disclose a kind of plastic casing with core location bolt in 201220493320, include plastic capacitor shell, be provided with the cylindrical pilot pin corresponding with the mandrel through hole internal diameter of capacitor core body in described plastic capacitor shell interior bottom portion center.Described cylindrical pilot pin is together injection molded with plastic capacitor shell.This technical scheme has ensured capacitor assembling placed in the middle and vertical in plastic casing, simple in structure, reasonable in design, and low cost of manufacture is easy to assembly, practical.But this technical scheme necessarily requires have mandrel through hole just can position on core body, therefore this technical scheme scope of application is little, can not satisfy the demand.
Utility model content
For the problems referred to above, the utility model provide a kind of effective to core location, can seal completely and plastic capacitor shell simple in structure core body.
In order to address the above problem, the technical scheme that the utility model provides is:
A kind of plastic capacitor shell, comprises shell, core body, and the inwall of described shell is provided with the first fixing muscle, and the surface of the described first fixing muscle contacts with described core body, and the quantity of the described first fixing muscle is at least 2.By the first fixing muscle, core body is located between two parties, pouring material can be completely, uniformly core body is sealed.
Preferably, the inner side of described outer casing bottom is provided with the second fixing muscle.Outer casing bottom is also provided with the second fixing muscle, can better position core body, more completely, evenly core body is sealed.
Preferably, the described first fixing relative core body of the muscle center of circle is symmetrically arranged with 3.
Preferably, the surface of the described first fixing muscle is indent arc.The surface of the first fixing muscle is that indent arc can better contact with core body, better effects if.
Compared with prior art, the beneficial effects of the utility model are:
First, second fixing muscle of the present utility model can be good at core body to locate between two parties, more even when pouring material seals core body, seals completely; And simple in structure, easy operating, cost is low.
Brief description of the drawings
Fig. 1 is the utility model vertical view;
Fig. 2 is that the utility model A-A is to schematic diagram.
In figure: 1, shell, 2, first fix muscle, and 3, second fix muscle.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
In conjunction with Fig. 1, Fig. 2, a kind of plastic capacitor shell of the utility model, comprise shell 1, core body, the surface that the inwall of shell 1 is provided with the first fixing muscle 2, the first fixing muscle 2 contacts with core body, and the first fixing muscle 2 relative core body centers of circle are symmetrically arranged with 3, the inner side of shell 1 bottom is provided with the second fixing muscle 3, the surface of the first fixing muscle 2 is indent arc, can better contact better effects if with core body.By first, second fixing muscle, core body is located between two parties, pouring material can be completely, uniformly core body is sealed.
More than show and described general principle of the present utility model, 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 in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
