In the embodiment of the present application, since the battery core 30 and the battery tabs 20 are located in the housing 10, and the battery tabs 20 are connected to the battery core 30, the battery tabs 20 have The bending portion 21 is bent in a direction away from the battery core 30 . Therefore, the battery core 30 may collide with the bending portion 21 . Since one end of the casing 10 is provided with a folded top seal 40, the top seal 40 has a folding portion 41, and there is a gap between the folding portion 41 and the casing 10. The first connecting member 50 is disposed in the gap, and the folding portion 41 and the casing 10 10 is fixedly connected through the first connecting member 50. Therefore, it is equivalent to arranging the first connecting member 50 to make the folding portion 41 and the housing 10 become a whole, which is beneficial to reducing the shaking of the top seal 40, thereby reducing the battery core roll.

The connecting parts 70 are spaced apart on the side away from the folding part 41 , and a boss 71 is embedded in a groove 62 .

When the number of bosses 71 and the number of grooves 62 are multiple, and the plurality of grooves 62 and the plurality of bosses 71 are spaced apart, at this time, when the second connecting member 70 rocks with the folding part 41 , multiple bosses 71 can make the circuit board 60 shake at the same time, that is, the pull or push force is transmitted to the circuit board 60 through the bosses 71, and the circuit board 60 also provides resistance to the folding part 41 through the bosses 71, thereby reducing the shaking of the folding part 41 . In addition, the plurality of bosses 71 are spaced apart, which can also allow different parts of the second connecting member 70 to transmit the pulling force or pushing force of the folding portion 41 , that is, the force transmission position of the second connecting member 70 is increased, which is beneficial to the second connecting member. 70 transmits force to the circuit board 60. In addition, by providing a plurality of bosses 71 and one boss 71 being embedded in the groove 62 on a circuit board 60 , the connection between the circuit board 60 and the second connecting member 70 can be made more secure.
