Compared with prior art, in use, fixing the positive and negative anodes cover board of battery by the way of crimping, solve existing adopt
The problem of existing of high cost when being fixed with welding equipment.
Brief description of the drawings
Fig. 1 is that the utility model embodiment provides a kind of explosive view of circular batteries structure；
Fig. 2 is the partial enlarged view at A in Fig. 1.
Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining
The utility model, is not used to limit the utility model.
The utility model embodiment provides a kind of circular batteries structure, and as shown in Figs. 1-2, it includes shell 1, battery core 2, just
Polar cap plate 3, anode cover board 4 and pole plate 5, battery core 2 are arranged in shell 1, and pole plate 5 is arranged on the both ends of battery core 2 and leads to respectively
Cross cathode cover board 3 and anode cover board 4 is fixed；The both ends of shell 1 are respectively arranged with flange 6, and flange 6 is by the cathode at 2 both ends of battery core
Cover board 3, anode cover board 4 and 5 crimping of pole plate are fixed, and the shape and the shape of pole plate 5 at 2 both ends of battery core match, in this way, using pole
Plate 5 connects battery core 2, and connection mode is more firm, and the positive and negative anodes cover board of battery is fixed by the way of crimping, solves existing
The problem of existing of high cost when being fixed using welding equipment.
Further comprise gasket 7, gasket 7 is provided with two, respectively positioned at cathode cover board 3 and pole plate 5 and anode
Between cover board 4 and pole plate 5, further comprise felt pad 8, felt pad 8 is provided with two, is respectively sleeved at cathode cover board 3 and bears
On polar cap plate 4, in this way, realizing insulated enclosure with felt pad 8 and gasket 7, ensure that the shell of battery is not charged.
Liquid injection hole 9 is additionally provided with the pole of anode cover board 4, the explosionproof hole 10 for pressure release is provided with anode cover board 4,
In this way, carrying out fluid injection by liquid injection hole, when cell pressure is excessive the explosion-proof valve being welded at this can be made to pop.
Application method：In use, opening liquid injection hole in the position of pole, facilitate the fluid injection in production process to operate, simplify life
Production. art；Explosionproof hole is provided with cover board, when cell pressure is excessive the explosion-proof valve being welded at this can be made to pop, played
The effect of safeguard protection, the mode that crimping is fixed can reduce welding, reduce the cost of production, using double insulation with sealing,
Ensure that the leakproofness of battery is good.
Using the above scheme, compared with prior art, in use, fixing the positive and negative polar cap of battery by the way of crimping
Plate, solves the problems, such as existing of high cost during the existing fixation using welding equipment.
The above, is only the preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
It is subject to scope of the claims.
