[0021] The electrode tab 502 is disposed in the contact cavity 501a. The electrode tab 502 includes an upper contact portion 502a and a lower contact portion 502b. The left end of the upper contact portion 502a and the left end of the lower contact portion 502b are connected by a connecting portion 502c. The connecting portion 502c is provided with a second connecting hole 502d corresponding to the first connecting hole 501b.
