Description
Technical field
The invention belongs to energy storage device technical field, be specifically related to a kind of ultracapacitor.
Background technology
Along with the popularization and application of automobile, cause the aggravation that petroleum-based energy consumes, motor vehicle exhaust emission simultaneously also increases day by day, causes serious pollution to the biological environment of the earth.Therefore find a kind of efficient, pollute little energy substitution petroleum-based energy and become very urgent and needs, this is also the reason greatly developed of power vehicle over the years.Ultracapacitor has the features such as energy density is large, transient current is large, memoryless benefit, long service life because of it, is widely used in electric automobile and military field.
Ultracapacitor comprises for splendid attire pole group and is welded on the housing of upper end open of upper and lower collector of group upper and lower end face, pole and the upper cover for the opening part that covers housing.Upper and lower collector is welded respectively in the group upper and lower end face, pole reeled in current ultracapacitor; Upper collector welds the link of similar lug, then the link of this similar lug is welded together by the mode and upper cover penetrating upper cover sidewall in outside; Next part fluid welds the link of similar lug, then by the link of this similar lug in outside by penetrating the mode of housing sidewall together with case weld.Take into account weld strength due to the mode penetrating welding and sealing is very difficult, very easily easily produce the bad problem of weld strength difference or electrolyte leakage, and not easily find, great impact is caused on the use of client's electrical appliance.
Therefore, at present in the urgent need to developing a kind of ultracapacitor, increasing pole group and being connected reliably with upper cover and housing, reducing risk of leakage, thus improve quality, the raising production yields of ultracapacitor.
Summary of the invention
The object of the invention is to the technical problem described in solving and provide one can ultracapacitor.
For realizing described object, the present invention adopts following technical scheme:
A kind of ultracapacitor, comprise pole group, the upper collector being welded on two end faces up and down of described pole group respectively and next part fluid, for being set with the housing of the both ends open up and down of the pole group with described upper collector and next part fluid from bottom and covering the upper cover of the described upper collector held on the housing, the external diameter of described upper collector is identical with the lower outer diameter of described upper cover, thus described upper collector can be alignd with upper cover coordinate.
Described upper collector is directly welded to connect at the matching part that aligns with described upper cover.
The bottom surface of described next part fluid sets firmly a pole, establishes one to make described pole can coordinate the perforate passed in the bottom of described housing.
Described pole comprises pole platform, and described pole platform sets firmly a terminal post.
The shape of described pole platform is identical with the shape of described housing bottom perforate.
Described terminal post can pass from described housing bottom perforate.
After described terminal post passes from described housing bottom perforate, described pole platform is concordant with the shell bottom surface of described housing.
Described pole platform taps into row with described housing at the concordant position straight in shell bottom surface and is welded to connect.
Ultracapacitor of the present invention due to the external diameter of upper collector identical with upper cover lower outer diameter, and cooperation of can aliging, therefore, collector can be made to weld at position of aliging with upper cover, thus eliminate other link, because the part of welding is not by upper cover sidewall, so weld strength can ensure, and sealing can not be affected.
In addition, because the terminal post of group bottom, pole can pass from perforate at the bottom of shell, and pole platform is concordant with shell baseplane at the bottom of shell, therefore, in flush position, pole platform and shell back welding can be connect, not pass through housing sidewall, can weld strength be ensured, and not affect sealing.
Therefore, the quality that the present invention can significantly improve ultracapacitor increases soldering reliability, reduces disclosure risk, is conducive to the yields improving production operation, applies aborning widely, be of great practical significance.

Embodiment
Below, in conjunction with example, substantive distinguishing features of the present invention and advantage are further described, but the present invention is not limited to listed embodiment.
Shown in Fig. 1-7, a kind of ultracapacitor, comprise pole group 5, be welded on the upper collector 1 of two end faces up and down of described pole group 5 and next part fluid 4 respectively, for being set with the housing 6 of the both ends open up and down of the pole group with described upper collector and next part fluid from bottom, and cover described housing 6 upper end described on the upper cover 7 of collector, the external diameter of described upper collector is identical with the lower outer diameter of described upper cover, thus described upper collector can be alignd with upper cover coordinate.
Wherein, collector is directly welded to connect at matching part 10 place of aliging with described upper cover on described, and without link transition, or do not utilize the sidewall of described housing to weld.
Described upper collector coordinates owing to can align with described upper cover, thus can directly collector on described be directly welded to connect at the matching part that aligns with described upper cover when welding, because described upper collector and upper cover welding position be not through upper cover sidewall, the basis ensureing weld strength avoids the leakage hidden danger penetrating and weld and bring, significantly improve the quality of ultracapacitor, improve production yields, be conducive to applying aborning widely, be of great practical significance.
As further improvement, the bottom surface of described next part fluid sets firmly a pole, the perforate 8 of establishing described pole can be coordinated in the bottom of described housing 6 to pass.
It should be noted that, the described pole shape set firmly in the bottom surface of described next part fluid can be circular or square, or other bodies, the hole shape offering perforate at the bottom of a shell at described housing bottom can be circular or square, or other shape, adapt with the shape of pole, described pole can be coordinated and pass.
Preferably, in the present invention, described pole comprises pole platform 2, described pole platform sets firmly a terminal post 3.
Wherein, the shape of described pole platform is identical with the shape of described housing bottom perforate 8, can be circular or square, or other geometry.
Concrete, after adopting the pole of this band pole platform, described terminal post 3 can pass from described housing bottom perforate 8.
Further, after described terminal post 3 passes from described housing bottom perforate 8, described pole platform 2 is concordant with the shell baseplane 9 of described housing 6.
Further, described pole platform 2 is directly welded to connect at concordant position 11, shell baseplane 9 place with described housing 6, and does not utilize the sidewall of described housing to weld.
It should be noted that, because described terminal post 3 housing is through the described bottom opening 8 bottom described housing 6, and described pole platform 2 is concordant with described housing 6 bottom surface, thus pole platform directly can be welded in flush position with housing bottom, and unnecessaryly to be welded by housing sidewall, therefore in concordant position, described pole platform 2 is welded to connect with described housing 6, thus welding can be made not pass through housing sidewall, ensureing on the basis that welding is strong, avoid the risk of leakage, improve production yields, be conducive to applying aborning widely, be of great practical significance.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
