[0025] Embodiment: As Figures 1-5As shown in the figure, a new type of rechargeable battery includes a housing 1 with an assembly space inside and a charging interface 10 at the bottom. Inside the housing 1, there are a contact member 11, a battery cell 12 with a first electrode 121 at one end and a second electrode 122 at the other end, and a circuit board 13 electrically connected to the charging interface, which are assembled in sequence from top to bottom. The contact member 11 is electrically connected to the first electrode 121 and the circuit board 13 is electrically connected to the second electrode 122. The contact member 11 is at least partially exposed outside the housing 1 through a through hole 100 at the top of the housing 1. It also includes a conductive wire 14 with one end connected to the first electrode 121 and the other end connected to the circuit board 13. A relief groove 140 corresponding to the conductive wire 14 is provided on the inner wall of the housing 1, and at least part of the conductive wire 14 is placed in the relief groove 140. The relief groove 140 is recessed inward from the inner wall of the housing 1, and the height of the relief groove is greater than the sum of the heights of the circuit board and the battery cell. The structure of this application can prevent the conductive wire from being pressed by the battery cell or being subjected to unnecessary physical stress, reducing problems such as breakage or deformation caused by stress concentration, thereby protecting the integrity of the conductive wire to a certain extent and extending its service life.
[0026] Among them, the conductive wire 14 includes a connecting portion 141 placed in the relief groove 140. One end of the connecting portion 141 is electrically connected to the circuit board 13. The conductive wire 14 includes a contact portion 142 electrically connected to the first electrode 121. One end of the connecting portion 141 far from the connection with the circuit board 13 is connected to one side of the contact portion 142.
