Abstract
The utility model discloses a large capacity battery electrode extraction device. The battery pole column anti-rotation clamping plate is arranged under the battery cover, the anti-rotation hole is formed in the anti-rotation clamping plate, one section of the battery pole column is embedded in the anti-rotation hole in the anti-rotation clamping plate, and a sealing device is arranged between the battery pole column hole in the battery pole column and the battery cover and the anti-rotation hole in the anti-rotation clamping plate. The extraction device can effectively prevent the rotation of the battery pole when the battery is used, and simultaneously effectively solves the sealing problem, thereby greatly improving the safety of the battery.
Description
Technical field
The utility model belongs to high capacity cell electrode ejector, is specifically related to the high capacity cell electrode ejector of a kind of battery electrode column anti-rotation and sealing.
Background technology
The battery electrode ejector of the present square column type battery of high-capacity lithium-ion comprises establishes the pole hole on the battery cover, battery electrode column passes the pole hole, connects insulating pad and clamp nut on the battery electrode column.There are the following problems for this device: sealing ring adopts " O " shape sealing ring, and this sealing ring compresses the back distortion, causes sealing effectiveness bad; Battery electrode column easily rotates, and causes potential safety hazard for the use of battery.
Summary of the invention
The purpose of this utility model is to provide a kind of high capacity cell electrode ejector, to address the above problem.
The technical solution of the utility model is: high capacity cell electrode ejector comprises battery cover, establish the pole hole on the battery cover, battery electrode column passes the pole hole, connect insulating pad and clamp nut on the battery electrode column, battery cover has the anti-rotation clamp, establish battery electrode column anti-rotation hole on the anti-rotation clamp, in one section anti-rotation hole that is embedded on the anti-rotation clamp of battery electrode column, establish sealing device between the pole hole on battery electrode column and the battery cover, the anti-rotation hole on the anti-rotation clamp.
When this ejector can prevent effectively that battery from using, the rotation of battery electrode column had solved sealing problem, the fail safe that has improved battery greatly simultaneously again effectively.
