Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model and Advantageous Effects thereof are described in detail, but the utility model is not limited to this.
Embodiment 1
As shown in Figure 1 to Figure 3, the covering plate structure of a kind of aluminum-shell battery that the utility model provides, comprise cover board body 1, cover board body 1 is provided with negative pole rivet hole 2, be inserted with negative pole rivet 3 in negative pole rivet hole 2, be provided with sealing ring 4 between negative pole rivet 3 and negative pole rivet hole 2, the bottom of sealing ring 4 is provided with brace 5, the surrounding of brace 5 is provided with insulation spacer 6, and insulation spacer 6 is arranged on the lower surface of cover board body 1.Sealing ring 4 can isolate negative pole rivet 3 and cover board body 1, and can effectively prevent negative pole rivet 3 from contacting with cover board body 1 or aluminum hull, fail safe is good.Wherein, sealing ring 4 forms between negative pole rivet 3 and negative pole rivet hole 2 by the mode of injection moulding, and negative pole rivet 3 and sealing ring 4 tight fit, the lower end of negative pole rivet 3 is connected by spot welding with brace 5.In addition, by arranging one piece of insulation spacer 6 around the brace 5 be positioned at below negative pole rivet 3, thus make the negative electrode lug of battery core core in assembling process not easily encounter place beyond brace 5, thus effectively prevent short circuit, prevent battery core from exploding because of internal short-circuit, improve the security performance of battery core.
