Shell, also includes that end face is provided with the plastic inner shell of opening, and described electrolyte contains in described battery core and described moulds
Between material inner shell, described plastic inner shell end face is provided with caulking gum.
Wherein, described shell is made up of drain pan and cap, and described drain pan and described cap are fastened and connected,
Described base side walls is provided with radiating block, is provided with identical described radiating block on described cap inner roof wall,
Described radiating block and the laminating of described inner shell outer wall.
Wherein, be circumferentially with draw-in groove at described drain pan end face, described cap diapire outer circumferentially arranged with institute
State the clamp of pocket matches.
Further, in the middle of described cap, it is provided with upwardly extending lobe, described lobe inner hollow,
Described upper conductor extends in described lobe through described plastic inner shell, described caulking gum.
Further, the length of described clamp is more than the degree of depth of described draw-in groove.
Further, described plastic inner shell end face and described card groove bottom level, the length etc. of described clamp
Thickness and the thickness sum of described caulking gum in described radiating block.
Wherein, it is metal material outside described drain pan and described shell.
This utility model has the advantage that and good effect is: this utility model sets between shell and inner shell
There is radiating block, inside battery heat quickly can be conducted outside metal shell, it is to avoid inside battery temperature
