Description
Technical field
The present invention relates to electric capacity manufacturing technology field, refer in particular to a kind of bipolar aluminium electrolytic capacitor.
Background technology
Electric capacity 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.In electronic production, need to use various capacitors, they play a different role respectively in circuit.Similar to resistor, electric capacity is called in letter conventionally, by letter C, represents.As its name suggests, capacitor is exactly " container that stores electric charge ".Although capacitor is various in style, their basic structure and principle are identical.In the middle of the metal of two close proximity, by something solid, gas or liquid, separated, just formed capacitor.Two metals are called pole plate, and middle material is called medium.Capacitor be also divided into capacity fixing with volume-variable.But the electric capacity of fixed capacity commonly, the most common is electrochemical capacitor and ceramic disc capacitor.The basic role of capacitor is exactly charge and discharge, but substantially discharges and recharges by this many circuit phenomenons that effect extends out, and makes capacitor have all different purposes, for example: in electro-motor, with it, produce phase shift; In photoflash, with it, produce high-octane spark etc.And in electronic circuit, capacitor purposes of different nature is especially many, these many different purposes, although also there is completely different part, because its effect is all from charge and discharge.Existing electrochemical capacitor is to adopt the structure of one deck paper one deck paper tinsel to roll mostly, and its pin is also positive negative the two poles of the earth, adopts this structure, and electrolytic paper is easily breakdown; And the electrolytic paper, the aluminium foil that need while rolling are all longer, after making impedance large, useful life is short.
Summary of the invention
Object of the present invention is overcoming the deficiencies in the prior art, a kind of simple in structure, long service life is provided, is not easy the bipolar aluminium electrolytic capacitor that punctures, capacity is large, impedance is low.
For achieving the above object, technical scheme provided by the present invention is: a kind of bipolar aluminium electrolytic capacitor, described capacitor is by multilayer electrolytic paper and the mutual roll-forming of aluminium foil, described layer totally eight layers of electrolytic paper and the four layers of aluminium foil of rolling, described in roll laminated construction adopt outermost layer be one deck electrolytic paper, then one deck aluminium foil, more two-layer electrolytic paper, one deck aluminium foil, two-layer electrolytic paper, one deck aluminium foil, two-layer electrolytic paper, one deck aluminium foil, in the mode roll-forming of one deck electrolytic paper; Capacitance pole pin includes anodal pin a and anodal pin b, negative pole pin a and negative pole pin b, and wherein, anodal pin a and anodal pin b are riveted on respectively on the aluminium foil of outermost layer and inner one deck, and negative pole pin a and negative pole pin b are riveted on respectively on outer one deck and innermost layer aluminium foil.
The impregnation method of the capacitor of above-mentioned making is: first, the capacitor for the treatment of impregnation is put into impregnation cylinder in order, capacitor after putting into seals impregnation cylinder; Then impregnation cylinder is vacuumized, when vacuumizing, make moisture and air in capacitor be drawn out of; Open communicating valve, make the electrolyte suction impregnation cylinder in liquid storing barrel, close communicating valve; Apply malleation to the impregnation cylinder after vacuumizing, malleation value is 1.5MPa, and then pressurize carries out impregnation to capacitor, and the impregnation time is 40 ~ 120 minutes; Discharging impregnation cylinder pressure is normality, keeps 15 ~ 20 minutes; Again impregnation cylinder is vacuumized; Open communicating valve, make the electrolyte suction impregnation cylinder in liquid storing barrel, close communicating valve; Apply malleation to the impregnation cylinder after vacuumizing, malleation value is 1.3MPa, and then pressurize carries out impregnation to capacitor, and the impregnation time is 40 ~ 120 minutes; Discharging impregnation cylinder pressure is normality, keeps 10 ~ 15 minutes; Again impregnation cylinder is vacuumized; Open communicating valve, make the electrolyte suction impregnation cylinder in liquid storing barrel, close communicating valve; Apply malleation to the impregnation cylinder after vacuumizing, malleation value is 1.2MPa, and then pressurize carries out impregnation to capacitor, and the impregnation time is 40 ~ 120 minutes; Discharging impregnation cylinder pressure is normality, makes under the effect of pressure differential, to flow back to liquid storing barrel containing immersion liquid; Capacitor taking-up after impregnation is dried.
The electric capacity that this programme is made adopts double-deck electrolytic paper, can effectively prevent from puncturing, reduce electric capacity height; Manufacture the aluminium foil of use and the length of electrolytic paper and reduced by one times, impedance has also reduced by one times, greatly increases capacitance; Compare with existing electric capacity, this programme can adopt shorter electrolytic paper and aluminium foil to roll, and increases utilization rate of raw materials, saves manufacturing cost.
