Description

A kind of aluminum hull of electrolytic capacitor
Technical field
The utility model is related to capacitor technology field, and in particular to a kind of aluminum hull of electrolytic capacitor.
Background technology
People are generally derived from their outward appearance to the first impression of article.For electronic component, we are first What is seen is exactly their encapsulation class;Electrolytic capacitor is made up of aluminum hull and capacitor core.Aluminum hull is the outer of electrolytic capacitor Shell, with protection capacitor core, isolation capacitor core and extraneous effect.The aluminum hull of capacitor of the prior art is by aluminium It is stamped to form, in order to prevent capacitor core from being contacted with aluminum hull, aluminum hull can be made to make the failures such as capacitor core short circuit, in aluminum hull Outer surface is each coated with one layer of dielectric film, and capacitor can generate heat under normal usage, the presence of insulating barrier, can cause nothing Method radiates, and making the service life of capacitor reduces, or even has the possibility of blast, and the life to consumer causes safely serious shadow Ring, capacitance core is manufactured and the enterprise of sale produces extremely bad influence.
It with polypropylene film is main medium that existing freezer compressor capacitor and many air conditioner capacitors with lead are Material, zinc-aluminium metal layer is as electrode roll around forming.Epoxy coating is put in a plastic housing and then irrigated to the core body of winding, To reach the purpose of sealing.Extraction electrode is lead, and lead two ends are directly welded at core body both ends of the surface, after core body is completed, Although there is epoxy to encapsulate between gilding layer, lead, shell, it is easy to produce gap, it is difficult to meet present capacitor use Environmental requirement.This electric capacity use time is slightly long, and the aqueous vapor in air will enter electric capacity along lead gap, cause capacitor Core metal layer oxidation, causes condenser capacity to decay, and loss becomes big.
Utility model content
The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of aluminium of electrolytic capacitor Shell, its simple structure, perfect heat-dissipating, good airproof performance, can increase the service life, good stability, it is safe and reliable, be easy to peace Fill and use.
In order to solve the problems existing in background technology, the utility model is to use following technical scheme:One kind electrolysis electricity The aluminum hull of container, it includes shell, cover plate;Described cover plate bottom is provided with explosion-proof covering board at described shell aperture;Institute The explosion-proof covering board stated is provided with corresponding connecting hole with described cover plate;Lead terminal is provided with described cover plate; Capacitor core is provided with described shell;Lead at the top of described capacitor core sequentially passes through Explosion-proof cap by connecting hole Plate, cover plate, extend to lead terminal outside;Sealing ring is provided with described connecting hole;Described sealing ring and connecting hole phase Connect;Fuse is provided with described lead, enclosure is may be contained within.
Further, it is provided with dielectric film between described shell and capacitor core outer surface;Described insulator film thickness It is 5-12mm.
Further, described lead terminal is spring-piece type lead terminal.
Further, described explosion-proof covering board thickness is 0.5-0.7mm.
When the utility model is operated, capacitor the inside is in layer made up of conductive film and insulating paper, in use Probably due to overcurrent, overvoltage etc. puncture, such capacitor will result in short circuit, be set between shell and capacitor core outer surface There is dielectric film, using this layer of dielectric film aluminum hull inner body wall can be prevented directly to be contacted with the negative and positive the two poles of the earth in capacitor core and make electricity Container produces short circuit, while being provided with fuse on lead, when soft fault occurs in capacitor, fuse will play protection Effect, accident is limited within minimum zone, reduces the explosion phenomenon that electric capacity causes by internal short-circuit, connecting hole interior sealing Circle, minimum is reduced to by the gap of lead and connecting hole contact surface, shell and the sealing property of cover plate is substantially strengthened.
The utility model beneficial effect:Its simple structure, perfect heat-dissipating, good airproof performance, can increase the service life, stabilization Property is good, safe and reliable, be easily installed and use.
Brief description of the drawings
Accompanying drawing described herein is further understood to of the present utility model for providing, and constitutes of the application Point, but do not constitute to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the utility model structural representation;
Description of reference numerals:1- shells;2- connecting holes;3- leads;4- lead terminals;5- sealing rings;6- cover plates;7- is explosion-proof Cover plate;8- fuses;9- capacitor cores;10- dielectric films.
Specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, illustrative examples therein with And explanation is only used for explaining the utility model, but it is not intended as to restriction of the present utility model.
As shown in figure 1, this specific embodiment uses following technical scheme:A kind of aluminum hull of electrolytic capacitor, it includes Shell 1, cover plate 6;The described bottom of cover plate 6 is provided with explosion-proof covering board 7 at the described opening of shell 1;Described explosion-proof covering board 7 With corresponding connecting hole 2 is provided with described cover plate 6;Lead terminal 4 is provided with described cover plate 6;Described is outer Capacitor core 9 is provided with shell 1;The lead 3 at the top of described capacitor core 9 by connecting hole 2 sequentially pass through explosion-proof covering board 7, Cover plate 6, extend to the outside of lead terminal 4;Sealing ring 5 is provided with described connecting hole 2;Described sealing ring 5 and connecting hole 2 It is matched;Fuse 8 is provided with described lead 3, be may be contained within inside shell 1.
Further, dielectric film 10 is provided between described shell 1 and the outer surface of capacitor core 9;Described dielectric film 10 thickness are 5-12MM.
Further, described lead terminal 4 is spring-piece type lead terminal.
