Description
Technical field
The utility model relates to capacitor, especially a kind of high frequency tolerant, rapid heat dissipation, electrolytic capacitor with long service life.
Background technique
Capacitor is one of the electronic component largely used in electronic equipment, be widely used in blocking, coupling, bypass, filtering,
Resonant tank, energy conversion, control circuit etc..It needs to use various capacitors in electronic production, they are in electricity
It plays a different role respectively in road, the ability of existing capacitor high frequency tolerant is general, and service life is also shorter.
Utility model content
In order to solve the above technical problems, the purpose of the utility model is to provide a kind of high frequency tolerant, rapid heat dissipation, long service life
Electrolytic capacitor.
The technical solution adopted in the utility model is:
A kind of electrolytic capacitor, including winder and at least two pins, the winder by anode foils, Cathode Foil,
The first electrolytic paper in anode foils and the second electrolytic paper coiling and molding in Cathode Foil, the centre of the anode foils
Position cold riveting has positive chaff, and the middle position cold riveting of Cathode Foil has cathode chaff, the anode chaff and at least one pin
Connection, cathode chaff are connect at least one pin.
The utility model further includes insulation crust, and the winder is arranged inside insulation crust, is arranged on insulation crust
There is the through-hole stretched out for pin to outside.
The opening of the through-hole is provided with the rubber plug for sealing, and the rubber plug is around pin periphery.
Second electrolytic paper, anode foils width be smaller than the width of Cathode Foil, Cathode Foil is fitted in insulation crust
Portion.
One layer of protection layers of foil or guarantor are all covered at the cold riveting of the anode chaff and anode foils, cathode chaff and Cathode Foil
Protect paper layer.
The utility model has the beneficial effects that
The utility model carries out cold riveting in the middle position of anode foils and Cathode Foil, draws foil in the middle position of aluminium foil
Item, riveting point is cancelled out each other in the magnetic field that middle position can allow both sides different directions to be formed, so that induction reactance is reduced, such capacitor
Energy high frequency tolerant, the ability that ripple current is born in negative foil contact improve, and Cathode Foil contacts insulation crust, is conducive to radiate, simultaneously
Also service life is extended.
Detailed description of the invention
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is another structural schematic diagram of the utility model.

Specific embodiment
As shown in Figure 1-Figure 3, a kind of electrolytic capacitor, including winder 1 and at least two pins 2, the winder 1
By anode foils 11, Cathode Foil 12, the first electrolytic paper 13 in anode foils 11 and the in Cathode Foil 12 second electrolysis
14 coiling and molding of paper, the middle position cold riveting of the anode foils 11 have positive chaff 5, and the middle position cold riveting of Cathode Foil 12 has negative
Pole chaff 6, the anode chaff 5 are connect at least one pin 2, and cathode chaff 6 is connect, at least one pin 2 in aluminium foil
Middle position draw chaff, riveting point middle position can allow both sides different directions formed magnetic field cancel out each other, to subtract
Few induction reactance, such capacitor energy high frequency tolerant, the ability for bearing ripple current improves, while also extending service life.
The utility model further includes insulation crust 3, and the winder 1 is arranged inside insulation crust 3, on insulation crust 3
It is provided with the through-hole stretched out for pin 2 to outside.The opening of the through-hole is provided with the rubber plug 4 for sealing, 4 ring of rubber plug
It prevents from revealing to be sealed processing to insulation crust 3 around 2 periphery of pin.Wherein the insulation crust 3 is aluminum shell, convenient for dissipating
Heat.
Second electrolytic paper 14, anode foils 11 width be smaller than the width of Cathode Foil 12, Cathode Foil 12 is fitted in absolutely
Inside edge shell 3, in order to the insulation crust 3 that Cathode Foil 12 can be exposed and fitting is external, realize that heat is transmitted, by insulation crust
3 disperse extra heat to outside, reduce temperature when electrolytic capacitor work, in the present embodiment, the first electrolytic paper
13 and second electrolytic paper 14 equivalent width.
One layer of protection is all covered at the anode chaff 5 and the cold riveting of positive cathode foil 11, cathode chaff 6 and Cathode Foil 12
Layers of foil or protection paper layer make it be not easy to be wounded by high-frequency current at the cold riveting for protecting cathode chaff 6 and Cathode Foil 12
It falls.
The foregoing is merely the preferred embodiments of the utility model, the utility model is not limited to above-mentioned embodiment party
Formula, if with essentially identical means realize the utility model aim technical solution belong to the protection scope of the utility model it
It is interior.
