Description
Technical field
The present invention relates to a kind of ultracapacitor, relate in particular to a kind of ultracapacitor and use covering plate structure.
Background technology
Ultracapacitor (Electric double-layer capacitor) is the electrochemical energy storage element between ordinary capacitor and chemical cell that development in recent years is got up; Because it has the power density height, recycle advantages such as long and charging rate of life-span is fast, has broad application prospects in multiple fields such as mobile communication, electric tool, solar power generation, wind power generation, information technology and electric automobiles.
Ultracapacitor commonly used; The metal shell that comprises the sealing of an end opening and the other end; The blind end of this metal shell stretches out and is formed with pole; Be equiped with the outside fuse that is coated by insulating material in this metal shell inside, after fuse was positioned at metal shell inside, the covering plate structure that uses end face to be provided with pole sealed the openend of this metal shell and forms the ultracapacitor monomer.
Traditional covering plate structure comprises seal cover that metal material is processed and the pole plate that electrically connects with seal cover; Center position has extended to form pole in the outer face of said seal cover; Said pole plate one end face is with after capacitor core is connected, the other end through clamping be connected the inner face that is positioned at seal cover and link to each other; Though this connected mode is simple, because pole plate is to link to each other through snap fit with seal cover, in long-term the use; Owing to reasons such as vibrations; Pole plate be easy to being connected of seal cover to break away from or take place looseningly, cause the internal resistance of ultracapacitor to become big, shorten useful life.
For this reason; There is part manufacturer that the covering plate structure of this structure is improved; Promptly at first carry out laser welding or riveted joint at ultracapacitor housing and pole plate; Seal cover is being riveted or the mode of laser welding is carried out the fixing of covering plate structure then, thus in operating process technology complicacy comparatively, production efficiency is very low.And when covering plate structure links to each other with the metal shell openend; Be short-circuited for avoiding covering plate structure and metal shell to be conducted; Usually the periphery at sealing lid and pole plate is arranged with dead ring respectively, through modes such as laser welding or roll extrusion cover plate is fixed on this metal shell then; Though this mode can realize the sealing to metal shell, in covering plate structure and metal shell openend connection procedure, be positioned at seal cover and pole plate periphery dead ring because of be heated or stressed be easy to take place damaged; Cause seal cover or pole plate to contact with metal shell; Because the seal cover outer face is provided with pole, the metal shell blind end also is provided with pole, when seal cover contacts with metal shell; Directly cause positive and negative terminals to link to each other, and then produce short circuit; Or cause the ultracapacitor electrolyte inside to flow out from the insulating case fold owing to reasons such as technology encapsulation cause dead ring to produce fold, cause the ultracapacitor life-span to be reduced.Based on above existing technological deficiency, be necessary that to traditional ultracapacitor, particularly its covering plate structure improves.
Summary of the invention
To the problem that exists in the prior art, the object of the present invention is to provide a kind of ultracapacitor to use covering plate structure, when its pole plate was connected with seal cover, technology was simple, connected reliable.
Another object of the present invention is to provide a kind of ultracapacitor to use covering plate structure, it can effectively prevent the ultracapacitor leakage.
In order to realize the object of the invention, the invention provides a kind of ultracapacitor and use covering plate structure, comprising: seal cover, process by metal material; And metal polar plate, link to each other with seal cover.Seal cover comprises: body, body comprise outer face and inner face; And the metal body, outwards protrude formation from the outer face of body, be provided with cavity in the metal body, the metal body comprises outer face and inner face, the outer face sealing of metal body, the inner face of metal body opens wide and is connected with the inner face of seal cover.Metal polar plate comprises matrix, and matrix comprises the outer face; And pole, outwards protrude formation from the outer face of matrix.The matrix size of the size of the body of seal cover and metal polar plate is suitable; The cavity size of the size of pole and metal body is suitable; Pole is installed in the cavity of metal body and is connected with the metal body.
Preferably, the outer face of the body of seal cover is that the high periphery in middle part is low and be step-like step end face; Seal cover also can comprise: annular projection is arranged at the peripheral position of this step end face integratedly.
Compared with prior art, the present invention has following beneficial effect:
1) pole of the present invention is arranged on the metal polar plate; Be provided with the metal body at seal cover; Metal polar plate connects with seal cover through pole mutually; Because it is to realize linking to each other through being connected between pole and the metal body that metal polar plate and seal cover link to each other, thus easy to operate in connection procedure, the production efficiency height.
2) seal cover of the present invention is that the high periphery in middle part is low and be step-like step end face; The peripheral position of this step end face and with the annular projection that is provided with of step end face one; Above this annular projection, cover and closely press sealing ring; Because after sealing ring received the extruding of annular projection, the bottom of sealing ring and annular projection pressed together and closely cooperate, and have played good sealing function.When even dead ring plays fold adopting dead ring, because the squeezing action of sealing ring and annular projection can prevent the ultracapacitor leakage.
