Abstract
The utility model discloses an electrolytic capacitor, which comprises an aluminum shell, a capacitor core, an electrolyte and a sealing rubber plug. The rubber plug is arranged at the opening of the aluminum shell. The capacitor core is composed of an anode positive foil, an electrolytic paper, and a cathode negative foil. The electrolyte is filled between the aluminum shell and the capacitor core. The electrolytic capacitor is better in insulating effect, reasonable in structure, good in sealing performance and long in service life. The leakage current of the electrolytic capacitor is 0.005*C*V per minute and the electrolytic capacitor is enabled to work at the temperature of 125 DEG C for a long time. Meanwhile, the loss of the electrolytic capacitor is 5% at the frequency of 120Hz.
Description
Technical field
The utility model relates to capacitor technology field, particularly relates to a kind of electrolytic capacitor.
Background technology
Along with the development of electronics industry, the technical performance of electronic product and production technology level all, improving, make the environment for use of capacitor more and more harsher.The serviceability temperature environment that general manufacturing works can guarantee is up to 105 degree.With respect to using under the application electricity-saving lamp of this product and electric ballast hot environment, there is very large defect.This electric capacity is practically applicable to small size, platypelloid type driving power and other control boards.Traditional processing technology and material adapted are made flattening product both at home and abroad at present, product electrical property standard is that leakage current is less than 0.04*C*V (per minute), loss is 25% (120HZ) the highest withstand voltage 450VDC that accomplishes, heatproof 105 degree, the heat problem that solves capacitor is also the problem that capacitor industry need to solve for a long time.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of electrolytic capacitor, to solve the existing problem of prior art.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of electrolytic capacitor, comprises aluminum hull, capacitor core, electrolyte and seal rubber plug; Described plug is arranged on the opening part of described aluminum hull, described capacitor core is comprised of the negative paper tinsel of the positive paper tinsel of anode, electrolytic paper and negative electrode, between described aluminum hull and capacitor core, be filled with electrolyte, described electrolyte is non-aqueous eletrolyte, and described electrolytic paper comprises outer electrolytic paper middle level electrolytic paper and internal layer electrolytic paper.
Optionally, described seal rubber plug is high leakproofness butyl rubber.
The utlity model has the advantages such as insulation effect is good, rational in infrastructure, good airproof performance, long service life.Leakage current reaches 0.005*C*V (per minute), and product ceiling voltage reaches 500VDC, can long-term work at 125 ° of temperature, and loss is 5% (120HZ).
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the utility model provides a kind of electrolytic capacitor, comprises aluminum hull 9, capacitor core 8, electrolyte and seal rubber plug 6; Described seal rubber plug 6 is high leakproofness butyl rubber, and sealing plug 6 is arranged on the opening part of aluminum hull 9.Between aluminum hull 9 and capacitor core 8, be filled with electrolyte (not shown in FIG.), the non-aqueous eletrolyte of the preferred high conductivity of this electrolyte, high flash over voltage.Capacitor core 8 is comprised of the positive paper tinsel 4 of anode, electrolytic paper, the negative paper tinsel 2 of negative electrode.On the positive paper tinsel 4 of its Anodic, riveted joint has positive wire 5, and on the negative paper tinsel 2 of negative electrode, riveted joint has negative wire 7, and this positive wire 5, negative wire 7 go between for high pressure changes into high-purity.Electrolytic paper comprises outer electrolytic paper 1, middle level electrolytic paper 10 and internal layer electrolytic paper 3, and its outer electrolytic paper 1, middle level electrolytic paper 10 and internal layer electrolytic paper 3 are selected high density and the strong double-face layered paper of absorbability.
The utility model electrolytic capacitor leakage current reaches 0.005*C*V (per minute), and product ceiling voltage reaches 500VDC, can long-term work at 125 ° of temperature, and loss is 5% (120HZ).
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
