Inventor thinks that it can be any one above-mentioned situation that seepage occurs, or the result that two or more situations acts on simultaneously arbitrarily.
Research based on above, the utility model people has proposed a kind of more simply to construct the structure that solves seepage, even if make when pole is subject to the external force perpendicular to its bearing of trend, between sealing resin and pole, be difficult for producing relative motion, realize excellent sealing.
The post sealing structure body of the storage battery that the utility model provides, comprising:

Described pole has a distolateral portion of terminal that possesses the structure that can be electrically connected to outside that is formed at described pole, and another shape distolateral and cross section the base portion different from described portion of terminal that is formed at described pole, described cross section and described first direction quadrature;
Described pole by described seal cavity around periphery on be formed with at least one projection or groove;
For described projection or groove, by described projection or groove, the size on described first direction is made as P, and by described projection or groove, the size in the second direction of the outer peripheral face quadrature with described pole is made as T, and ratio P/T is less than or equal to 0.8.
The storage battery that the utility model provides, comprising: above-mentioned post sealing structure body.
The stand-by power supply that the utility model provides, comprising: above-mentioned storage battery.
As can be seen from the above technical solutions, the utility model embodiment has the following advantages:
In the utility model embodiment, by groove or projection are set on pole, when pole is subject to small shaking occurs perpendicular to the external force of its bearing of trend, although weaken to some extent at the outer peripheral face of pole and the butt power between sealing resin, yet, because pole is subject to the external force perpendicular to its bearing of trend, at groove or high spot, particularly groove or projection bight, can form on the contrary the region that butt power strengthens, therefore, acid solution is difficult for revealing between pole and sealing resin, has realized excellent sealing.
