Abstract
The utility model discloses a sealing structure of a lithium battery pole post, relating to a battery pole post seal and aiming at providing the sealing structure of the lithium battery pole post with reliable sealing performance. The utility model has the technical scheme that the sealing structure comprises a pole post and a sealing cushion, a cylinder at the lower part of the pole post is arranged in a bottom hole of a battery shell groove, the sealing cushion is arranged between the cylinder of the pole post and the bottom hole wall of the battery shell groove, and sealant is arranged in an annular cavity between the groove wall of a battery shell and a step cylinder at the upper part of the cylinder of the pole post; and a horizontal hole is arranged in a square pole post body which is arranged above the step cylinder, a bolt penetrates through a gasket, a battery connecting piece and the horizontal hole of the square pole post body, and a screw cap is arranged on a bolt arranged at the other side of the square pole post body. The sealing structure has the advantage of reliable sealing performance compared with the prior art and can be used for a lithium battery.
Description
Technical field:
The utility model relates to the hermetically-sealed construction of a kind of battery electrode column sealing, particularly a kind of lithium ion battery pole.
Background technology:
Lithium battery develops to the high-power direction of high-energy, but the post sealing structure of the dynamic lithium battery that uses has two scarce limits at present, the one, what make pole and brace is connected closely that structure is that vertical nut is set on the pole, when tightening, can drive pole rotates, sealing meeting between pole and the housing is destroyed, and the 2nd, only be provided with a sealing gasket between pole and the housing, sealing reliability is relatively poor.
Summary of the invention:
The purpose of this utility model provides the hermetically-sealed construction of the reliable lithium ion battery pole of a kind of sealing property.The technical solution of the utility model is, comprise pole and sealing gasket, it is characterized in that: the cylinder of pole bottom places the bottom outlet of battery container groove, sealing gasket places between the bottom outlet wall of the cylinder of pole and battery container groove, is provided with fluid sealant in the annular chamber between the step cylinder on the cylinder top of the cell wall of battery container and pole; Be provided with lateral aperture in the square pole body above step is cylindrical, bolt is through in the lateral aperture of pad, cell connector and square pole body, is provided with nut on the bolt of the opposite side of square pole body.The utility model has the reliable advantage of sealing compared with the prior art.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, the lower cylindrical body of pole 2 places the hole of the bottom land of battery container 1, the cross section is that I-shaped sealing gasket 3 places between above-mentioned pole and the bottom land hole, filling epoxy resin forms sealant layer 4 in the annular chamber between the cell wall of the step cylinder of pole and I-shaped sealing gasket and battery container, for the ease of distinguishing, the red epoxy resin of filling in the groove of positive terminal, filling blue color circle epoxy resins in the groove of negative terminal, this sealing means can effectively prevent to reveal in the battery use, has improved the sealing property of battery.The stepped cylinder top of pole is square pole, is provided with the hole of level on this square pole body, and bolt 5 is through in the hole of pad, cell connector 6 and above-mentioned pole, with nut cell connector is closely contacted with the pole body.This fastening means can not cause pole to rotate, thereby has avoided owing to the rotation of pole sealing being damaged.
Claims (1)
