Abstract
An electrode leading-out sealing structure comprises a casing cover, wherein an electrode pillar hole is formed on the casing cover; an electrode pillar passes through the electrode pillar hole; and a sealing element is arranged between the electrode pillar and the electrode pillar hole. The electrode leading-out sealing structure is characterized in that an upper staking electrode pillar and a lower staking electrode pillar which are both cylindrical are arranged at both ends of the electrode pillar in the length direction; a conical electrode pillar with a gradually larger cross section extends from one end of the upper staking electrode pillar to one end of the lower staking electrode pillar; a polygonal fastening member extends outwards in the transverse direction between the lower staking electrode pillar and the conical electrode pillar; and the electrode pillar hole is provided with a polygonous positioning groove and a conical hole of which the shapes are respectively matched with the appearances of the polygonal fastening member and the conical electrode pillar.
Description
Technical field
The electrode that the utility model relates in the caps such as storage battery, large-scale capacitor device is drawn hermetically-sealed construction.
Background technology
In Chinese patent CN200820031646.6, disclose a kind of battery electrode and drawn hermetically-sealed construction, it comprises cap, pass pole and the seal washer between described cap and described pole that the pole hole is provided with on the described cap and be placed on the pole, at the seal washer of cap between brace.It is characterized in that: described pole coning, afterbody is square.Pole hole on the described cap cooperates with the pole outer rim, and along the pole outer wall, extends to described brace side.To certain position, be square.Square and the insulating washer of pole afterbody is wherein fastening.This method can effectively prevent to leak and simplify than initial anti-leakage structure.But also there is following shortcoming in it: the complex structure of described electrode column sealing plug, and its square-section can only process with planer, and difficulty of processing is big; Moulding in the pole hole of anti-rotation is of a specified duration service time, and its sealing effectiveness will variation, and the structure of its side's taper can make the easy seepage of electrolyte.
Summary of the invention
The battery electrode that technical problem to be solved in the utility model provides a kind of easy processing, can play fine antiseep effect is drawn hermetically-sealed construction.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is that a kind of electrode is drawn hermetically-sealed construction, and it comprises cap, offers the pole hole on described cap, in described pole hole, be equipped with pole, between described pole and described pole hole, be provided with seal; It is characterized in that described pole along the length two ends for having columniform riveting pole and the following riveting pole gone up, extend the conical pole that a cross section amplifies gradually from described downward riveting pole one end of riveting pole one end of going up, between described riveting pole down and described conical pole, laterally extend outward a polygonal retention means; Described pole hole has polygonal detent and round taper hole, and the polygonal retention means of its shape and described pole and conical pole profile are complementary.
Described polygonal retention means be triangle, quadrangle or pentagon other can not do shape in relative rotation can make its detent that embeds described pole hole the time.
The hollow shape seal that is coated on described pole periphery wall that its profile of described seal is and described pole hole profile is complementary.
It has conical pole pole of the present utility model, and this taper shape pole can well press together with the pole hole, further seals by inclined-plane extruding and seal, and its significant sealing affection can prevent that liquid from permeating away from inside battery; Secondly, this pole is not owing to have other transverse concave grooves or corner angle, and its processing is simple, saves cost of manufacture.

Embodiment
At the utility model, now lift a preferred embodiment and be elaborated in conjunction with graphic:
Storage battery shell and cover 2 offers the pole hole 21 that is complementary with pole 1 profile on cap 2, offer the detent that profile and cubic angle type retention means 13 profiles are complementary at pole hole 21 1 ends;
During assembling, seal 3 applyings are put in the pole hole 21, advance in the sealing part 3 pole 1 is nested then, make the conical pole periphery wall of pole 1 and the whole squeeze sealing members 3 in lower surface of cubic dihedral, and make pole 1 by in the nested fully pole hole 21 of advancing cap 2, squeeze sealing member 3 backs.The cubic dihedral retention means of pole sticks in the detent in pole hole 21, and it can avoid relatively rotating between pole 1 and cap.After assembling, reaching down at last riveting pole respectively, riveting pole riveted joint electrode extraction pole forms electrode.By conical pole periphery wall on the pole and cubic dihedral lower surface large tracts of land squeeze sealing member, realized the effect of large tracts of land sealing, and owing to each some extruding dynamics of conical pole periphery wall and seal is consistent, it does not seal the dead angle, there is not the long-time space that causes down of using of the inconsistent caused seal of Sealing Stress to occur yet, therefore, it has good antiseep effect.
Electrode of the present utility model is drawn hermetically-sealed construction and is not only applicable to storage battery, is applicable to that also the electrode of large-scale capacitor device is drawn hermetically-sealed construction.
Claims (3)
1. an electrode is drawn hermetically-sealed construction, and it comprises cap, offers the pole hole on described cap, is equipped with pole in described pole hole, is provided with seal between described pole and described pole hole; It is characterized in that described pole along the length two ends for having columniform riveting pole and the following riveting pole gone up, extend the conical pole that a cross section amplifies gradually from described downward riveting pole one end of riveting pole one end of going up, between described riveting pole down and described conical pole, laterally extend outward a polygonal retention means; Described pole hole has polygonal detent and round taper hole, and the polygonal retention means of its shape and described pole and conical pole profile are complementary.
2. electrode according to claim 1 is drawn hermetically-sealed construction, it is characterized in that the hollow shape seal that is coated on described pole periphery wall that its profile of described seal is and described pole hole profile is complementary.
