Technical field
The present invention relates to a kind of capacitor element, also relate to a kind of capacitor that utilizes this sub-prime to make, particularly a kind of film capacitor that utilizes this sub-prime to make.
Background technology
Capacitor is a kind of device of stored charge, realizes dynamic charge and discharge, and it is widely used in the middle of hyundai electronics, the electric equipment, and capacitor of the prior art has three drawbacks: the one, a little less than the shock resistance current capacity, when overload, damage easily; The 2nd, device work is in a single day breakdown, causes easily fire; The 3rd, the sub-prime of capacitor is very thin, and it is firm that external electrode is not easy to weld, and affects capacitor stability, causes easily damaging under impulse current.Some capacitors also adopt the aqueous chemical electrolyte, and its corrosivity is very strong, and fail safe is not high, also cause easily simultaneously environmental pollution.
Therefore, be necessary to provide a kind of sub-prime of easy welding electrode, to strengthen the welding performance of capacitor; Simultaneously, also be necessary to provide a kind of strong capacitor of ability of resistance to shock loads.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, and the film capacitor that a kind of capacitor element is provided and utilizes this sub-prime to make.
The technical solution used in the present invention is such:
A kind of capacitor element, comprise the electrode layer matrix, surface at described electrode layer matrix scribbles metal shielding, be used for improving the welding conductive performance of capacitor element, the position that is used for the welding extraction pole at the edge of described electrode layer matrix is provided with the margo layer of processing through thickening, the position that namely need to weld extraction pole at the sub-prime edge thickeies processing, to reach the purpose that makes things convenient for the welding between extraction pole and the sub-prime.Described electrode layer matrix is selected aluminium alloy material.
A kind of film capacitor, comprise a pair of aforesaid sub-prime, insulating medium layer, extraction pole, shell, fill between the described sub-prime and form described insulating medium layer, the margo layer of described a pair of sub-prime is drawn respectively described extraction pole, sub-prime, insulating medium layer and extraction pole are filled thing and are encapsulated in the shell, each sub-prime is drawn respectively two extraction poles, under the simple prerequisite of technique, has further improved the ability of capacitor shock resistance electric current.
Select epoxy resin for the filler that encapsulates described sub-prime, insulating medium layer and extraction pole in the shell.The epoxy resin can is safe and reliable, makes capacitor nontoxic without leaking, and is beneficial to environmental protection.Simultaneously, can also prevent the breakdown or overheated fire that causes of electric capacity, its shell inner stuffing is selected the environmental protection flame retardant material, is reduced under the abnormal conditions and brings safety problem because of the damage of capacitor.Be mainly used in refrigerator, air-conditioning, alternating current motor, water pump, generator, household electrical appliance, industrial electronics etc.
Described insulating medium layer is polypropylene film; The edge of described extraction pole and described sub-prime is by being welded to connect; The material of described shell is the environmental protection flame retardant material, more preferably ABS (acrylonitrile-butadiene-styrene copolymer) or PBT(polybutylene terephthalate (PBT)).
In sum, owing to adopted technique scheme, the invention has the beneficial effects as follows:
1, this product is that four pin pins are drawn, both ends of the surface are respectively drawn two pin pins, disperse the end face electric current during work, than single lead-out wire or leading foot pin have more good stability, shock-resistant electric current, the large current capacity of overload is strong, loss is little, insulation resistance is high, the nominal operation life-span is long, self-healing performance is excellent.
2, the can of built-in environmental protection flame retardant epoxy resin is safe and reliable, and capacitor is nontoxic without leaking and fluent material, is beneficial to the characteristics such as environmental protection.
