Description
Technical field
The invention belongs to the energy storage field of electrical components, relate to a kind of ultracapacitor.
Background technology
Ultracapacitor (Electric double-layer capacitor) is the electrochemical energy storage element between conventional general capacitor and battery that development in recent years is got up; Because it has the power density height, recycles the advantage that the life-span is long and charging rate is fast, has broad application prospects in multiple fields such as mobile communication, solar power generation, wind power generation, information technology and electric automobiles.
Ultracapacitor commonly used comprises metal shell, fuse and the cover plate of an end opening and other end sealing, and wherein the blind end of metal shell stretches out and is formed with pole, is equiped with the outside fuse that is coated by insulating material in metal shell inside; After fuse is positioned in the metal shell, use the openend of this metal shell of cover closure; The end of cover plate is provided with pole, is connected with pole plate in the fuse end near the metal shell blind end, and this pole plate is in order to electrically to contact with the blind end pole of metal shell.For preventing in use; Cause pole plate and the generation of metal shell blind end pole to break away from because of fuse produces to rock in metal shell, generally adopting the mode of laser welding or ultrasonic bonding to make fuse when contacting, be able to fix near metal shell blind end position with the metal shell maintenance is electrical through pole plate.
The ultracapacitor of this structure; Though pole plate is fixed on the metal shell; But because it is after fuse is installed in metal shell inside, to implement the pole plate welding; The welding position of pole plate in metal shell is difficult to confirm, and when welding, welding procedure, operation are all comparatively complicated; After welding finishes; If the welding quality of pole plate in metal shell is bad; After using after a while, fuse will produce in metal shell and rock, at this moment; The pole of pole plate that links to each other with fuse and metal shell blind end breaks away from, and causes ultracapacitor generation loose contact or makes whole ultracapacitor product rejection.
Therefore, based on above existing technological deficiency, be necessary traditional supercapacitor structures is improved.
Summary of the invention
To such an extent as to there is the complex process operating difficulties in the present invention, is prone to the problem that problems of welded quality causes pole plate to separate with metal shell blind end pole with the fixed form of metal shell welding for the fuse that solves traditional ultracapacitor, and proposes a kind of ultracapacitor.
The present invention realizes through following scheme:
Above-mentioned ultracapacitor comprises metal shell, cover plate and is contained in the fuse in the said metal shell, and said metal shell has the openend and the blind end of the other end relatively, and blind end stretches out and is formed with pole; Said fuse is provided with the pole plate that electrically contacts with said metal shell at the end near said metal shell blind end; Said pole offers tapped through hole downwards along self axis normal; Said pole plate is provided with the double-screw bolt that is complementary with said tapped through hole, and said pole plate screws in through this double-screw bolt in the tapped through hole of said pole and links to each other with pole.
Described ultracapacitor, wherein: the end of said tapped through hole is provided with in order to seal the sealing device of this tapped through hole.
Described ultracapacitor, wherein: said sealing device is to irritate the silica gel that is located in the said tapped through hole.
Described ultracapacitor, wherein: said sealing device is the bolt structure that is arranged with bonded washer; The said bolt structure that is arranged with bonded washer comprises screw and the bonded washer that is made up of plastic cement inner ring and metal outer ring; Said plastic cement inner ring is positioned at inboard, metal outer ring and is combined as a whole the aperture of said plastic cement inner ring and said screw interference fit with said metal outer ring.
Beneficial effect:
1, the present invention is through being provided with tapped through hole on the pole of metal shell blind end, and the pole plate setting of fuse and the double-screw bolt that tapped through hole is complementary screw in the tapped through hole by double-screw bolt is corresponding, can realize that fuse is connected with the assembling of metal shell; This connected mode is quick and easy and relatively more firm; Overcome that welding position in the prior art should not be confirmed, welding operation comparatively difficulty and cause problems of welded quality, the pole of pole plate and metal shell blind end breaks away from the use of having avoided causing because of problems of welded quality;
2, to irritate the sealing means establish silica gel simple for the end of tapped through hole of the present invention, good sealing effect, and cost is lower;
3, the end seal of tapped through hole of the present invention adopts the bolt structure be arranged with bonded washer, can be in use, meet the air pressure inside of this ultracapacitor when excessive; Guaranteeing under the conditions such as humidity and temperature environment; Rotary screw makes screw separate with tapped through hole or produces the gap, can discharge the inner air pressure of this ultracapacitor; Avoiding the generation of phenomenons such as ultracapacitor drum shell, sudden and violent valve, thereby make be able to prolong the useful life of ultracapacitor.
So ultracapacitor of the present invention has convenient, the firm advantage of fuse and metal shell assembling, and is simple to operate, product quality is able to guarantee, overcome fuse and rocked and influence the shortcoming that pole plate separates with metal shell blind end pole.
