Description

Capacitor with super capacity

The utility model belongs to the electronic devices and components field, particularly a kind of capacitor element of vast capacity.

In recent ten years; development along with the microcomputer application technology; various Artificial Intelligence Instruments, instrument are extensive use of single-chip microcomputer and dynamic and static memory is controlled and information storage; but in use; often because the unexpected power down of main power source, and cause program to lose, cause electronic installation to lose normal function; in order to protect unlikely the losing of dynamic and static memory internal information, on circuit, just need stand-by power supply of configuration.

Stand-by power supply is in the past usually selected battery; and common battery needs a voltage detection circuit and commutation circuit; during use not only change-over time long; and product structure complexity; cost improves; performance is also unreliable; if adopt rechargeable battery; not only price is higher; add charge protection during use again, and the number of times that discharges and recharges of rechargeable battery only has hundreds of time, just end useful life; if use the capacitor of a constant volume to discharge supply power; useful life can be longer, but existing aluminum capacitor volume is too big, and is very inconvenient during use; so it is gently little to be sought after developing a kind of volume; the novel energy storage unit that possesses capacitor and battery dual-use function simultaneously is as Artificial Intelligence Instrument; the stand-by power supply of instrument.

Early eighties, people utilize the interfacial electric double layer principle to make a kind of new electronic component, and its inside is to adopt elementary cell lamination packaged type structure, and it has the capacitor of vast capacity and the dual-use function of battery.With the capacitor with super capacity of living, its inner elementary cell is to adopt precious metal or graphite material to make collector electrode, material price is relatively more expensive, simultaneously, the graphite quality is crisp, only is suitable for manual operations, be not suitable for extensive explained hereafter, thereby the production prices height, the properties of product instability can't commercialization.In order to overcome above-mentioned defective, need develop a kind of parts industrial, cheap, stable performance that are fit to, as the elementary cell of vast capacity electric capacity.

Purpose of the present invention provides that a kind of dependable performance, cost are low, to be fit to what industrial with the capacitor with super capacity of rubber as inner elementary cell member.

The present invention relies on following technical proposals to realize, comprise in shell, contact conductor, the capacitor with super capacity that elementary cell constituted a kind of, each elementary cell is sealed ring and is formed the elementary cell box by accompanying in the middle of two conductive rubbers that are called collector electrode, two identical porous electrodes that are embedded with in the box by the boundary of one deck barrier film are constituted, according to the operating voltage requirement, one group of elementary cell is overlapped together, be encapsulated in formation integral capacitor in plastic sleeve and the metal shell.

One group of elementary cell can contain 8 to 8 elementary cells, and they closely overlap together, and is connected to electrode by graphite film and draws paper tinsel and draw.

Further specify embodiment below in conjunction with accompanying drawing.

Description of drawings:

Fig. 1 is one group of integral capacitor that the elementary cell encapsulation constitutes in the enclosure;

Fig. 2 is each elementary cell internal structure schematic diagram;

Among Fig. 1,1 is each elementary cell, and one group contains 6 to 7 elementary cells, and 2 draw paper tinsel in being, 3 is plastic sleeve, drawing, and 4 for having outer ring plate of drawing paper tinsel, covers above plastic sleeve, 5 is metal shell, the port flanging, and fastening inside components, 6 is outer packing plastic.Sidewall can be printed on the parameters of capacitor, and 7 is two-layer graphite film up and down.Play conduction.

Show the internal structure of each basic unit 1 among Fig. 2, wherein 11 is collector electrode, constitute by the sheet type conductive rubber, 12 for sealing ring, it is the garden ring plate shape of making by electro-insulating rubber, embedding is pressed in two collector electrodes, the component units box, 12 is two identical porous electrodes, it is made by absorbent charcoal material, accompany one deck plastic diaphragms sheet 14 in the middle of two porous electrodes as boundary, they together are inlaid in the unit box, constitute elementary cell one by one, and 6 to 7 elementary cells constitute one group, be encapsulated in plastic sleeve and the metal shell, constitute capacitor with super capacity.

The most significant advantage of this capacitor is, volume is little, capacity is big, in the use security good, fill Discharge life is long, can good desirable stand-by power supply as Artificial Intelligence Instrument, instrument.
