Abstract
A kind of solid capacitance core pack arrangement, positive pole riveting pin is identical with negative pole riveting needle construction, CP line, round bar part and flat part composition from top to bottom, when described positive pole aluminium foil, negative pole aluminium foil and electrolytic paper coaxially reel and form core bag, electrolytic paper top exceedes positive pole aluminium foil, negative pole Aluminium Foil Package wraps positive pole riveting pin and the whole flat part of negative pole riveting pin.The utility model electrolytic paper encases the junction of round bar part and flat part, like this in core bag formation process, because electrolytic paper has been filled electrolyte, electricity paper is close to round bar part and flat part, destroy the absorption of gas like this, avoid or reduce gas forming liquid and aluminium body to be separated, make the junction between round bar part and flat part change into better, surface alumina oxide film is deposited and is covered better.
Description
Technical field
The utility model relates to electronic devices and components, specifically, relates to a kind of solid capacitance.
Background technology
The good characteristic that the renewal product of solid capacitor operation conventional liquid electric capacity has it exclusive, structurally also continue to use the winding method of existing common liquid electric capacity, to rivet over respectively guide pin by cathode foil and anode foil, the interval of two-layered foil is with two electrolytic papers, the width of electrolytic paper is wider than two electrode foils, guarantee batching, to produce and in use procedure, two electrode foils can not contact, form the short circuit of product.Existing technology is the part that electrolytic paper exceeds electrode foil, and both sides are equal, this way, and equipment is ripe, and production operation is convenient, therefore no matter in liquid electric capacity or solid capacitor, has generally used this technology.
But there is inevitable problem in the solid capacitor product of pole low-leakage current, although reason is that guide pin changes into the aluminum lead making round bar part before making, change into round bar part and flat part after guide pin makes, but due in formation process, round bar part and flat part make draw in gentry's process define fresh by the aluminium surface changed into, in formation process, owing to producing gas, entering junction is together angle face, therefore gas is easily collected at this place, forming liquid and aluminium body can separate by the gas gathered, bad when causing junction physics and chemistry effect.After the core bag made with such guide pin, be also present in guide pin and change into same situation in core bag formation process, aluminium body and forming liquid separate in round bar part and flat part by the gas absorption of precipitation, make it to form good aluminium oxide rete.
In the manufacturing process of solid capacitor, because monomer and oxidant and aluminium have wettability.Because of a little at list
In body and oxidant impregnation process, oxidant and monomer can climb to the junction of round bar part and flat part, and form the path of conduction after polymerization, this will increase leakage current.
Utility model content
For solving above technical problem, the mode that the utility model adopts electrolytic paper different from the both sides allowance of cathode and anode paper tinsel.
Technical scheme is as follows:
A kind of solid capacitance core pack arrangement, be made up of positive pole aluminium foil, negative pole aluminium foil, electrolytic paper, positive pole riveting pin and negative pole riveting pin, its key is: described positive pole riveting pin is identical with negative pole riveting needle construction, CP line, round bar part and flat part composition from top to bottom, when described positive pole aluminium foil, negative pole aluminium foil and electrolytic paper coaxially reel and form core bag, electrolytic paper top exceedes positive pole aluminium foil, negative pole Aluminium Foil Package wraps positive pole riveting pin and the whole flat part of negative pole riveting pin.
Above-mentioned electrolytic paper top exceedes positive pole aluminium foil, the width of negative pole aluminium foil is a; Described electrolytic paper bottom exceedes positive pole aluminium foil, the width of negative pole aluminium foil is b, described a>b.Guarantee that the width of a at least can encase round bar part and flat part junction simultaneously.
Beneficial effect: the utility model electrolytic paper encases the junction of round bar part and flat part, like this in core bag formation process, because electrolytic paper has been filled electrolyte, electricity paper is close to round bar part and flat part, destroy the absorption of gas like this, avoid or reduce gas forming liquid and aluminium body to be separated, make the junction between round bar part and flat part change into better, surface alumina oxide film is deposited and is covered better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of positive and negative electrode riveting pin.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of solid capacitance core pack arrangement, be made up of positive pole aluminium foil 1, negative pole aluminium foil 2, electrolytic paper 3, positive pole riveting pin 4 and negative pole riveting pin 5, described positive pole riveting pin 4 is identical with negative pole riveting pin 5 structure, CP line, round bar part and flat part composition from top to bottom, when described positive pole aluminium foil 1, negative pole aluminium foil 2 and electrolytic paper 3 coaxially reel and form core bag, the whole flat part that electrolytic paper 3 top exceedes positive pole aluminium foil 1, negative pole aluminium foil 2 wraps positive pole riveting pin 4 and negative pole riveting pin 5.Described electrolytic paper 3 top exceedes positive pole aluminium foil 1, the width of negative pole aluminium foil 2 is a; Described electrolytic paper 3 bottom exceedes positive pole aluminium foil 1, the width of negative pole aluminium foil 2 is b, described a>b.Guarantee that the width of a at least can encase round bar part and flat part junction simultaneously.
Finally it should be noted that; foregoing description is only preferred embodiment of the present utility model; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite without prejudice to the utility model aim and claim; can make like multiple types and representing, such conversion all falls within protection range of the present utility model.
