[0025] like Figure 1 and 2 As shown, this utility model embodiment provides a pluggable battery pack, including a circuit board 200, two cylindrical batteries 100, a first insulating pad 300 and a second insulating pad 400.

[0026] Two cylindrical batteries 100 are spaced apart along their axial direction. A first insulating pad 300 is disposed between the two cylindrical batteries 100 and is bonded to the two cylindrical batteries 100 with adhesive. That is, the two cylindrical batteries 100 are fixed together by the first insulating pad 300 to facilitate subsequent assembly operations. Furthermore, a second insulating pad 400 is adhered to the opposite ends of the two cylindrical batteries 100 to prevent damage to the opposite ends of the two cylindrical batteries 100 and to improve service life.

[0027] Both ends of the cylindrical battery 100 are provided with tabs 110, one being the negative terminal and the other the positive terminal. Furthermore, the circuit board 200 is attached to the outside of the cylindrical battery 100 and extends along the axial direction of the cylindrical battery 100. Specifically, the circuit board 200 is attached to the outside of the cylindrical battery 100 with adhesive to fix the circuit board 200 and the cylindrical battery 100. It should be noted that the width of the circuit board 200 is smaller than the diameter of the cylindrical battery 100 to reduce the space occupied.

[0028] The circuit board 200 is provided with a series structure, and the tabs 110 on the opposite ends of the two cylindrical batteries 100 are electrically connected to the series structure, so that the two cylindrical batteries 100 are connected in series, that is, one of the tabs 110 on the opposite ends of the two cylindrical batteries 100 is a positive electrode and the other is a negative electrode.

[0029] Two first connection terminals 210 are provided on the side of the circuit board 200 away from the cylindrical battery 100. The two first connection terminals 210 correspond to and are electrically connected to the tabs 110 on the opposite ends of the two cylindrical batteries 100. Specifically, the tabs 110 on the opposite ends of the two cylindrical batteries 100 are bent at 90° and soldered to the corresponding first connection terminals 210.

[0030] One end of the circuit board 200 is exposed relative to the cylindrical battery 100, forming a plug-in end 220. Two external connection terminals 221 are provided on the side of the plug-in end 220 away from the cylindrical battery 100, which are arranged along the width direction of the circuit board 200. Two first connection terminals 210 are electrically connected to the two external connection terminals 221 respectively. Specifically, the first connection terminals 210 are electrically connected to the external connection terminals 221 through a power line. Furthermore, the plug-in end 220 is used to insert into the power socket on the electronic device. The socket is provided with elastic terminals corresponding to the external connection terminals 221. During assembly, the plug-in end 220 is inserted into the power socket, and the external connection terminals 221 will be electrically connected to the elastic terminals. Assembly is convenient and quick, which is conducive to new employees getting started quickly, and can effectively improve assembly efficiency and save costs.

[0031] In one embodiment, a first through hole 222 is provided on the plug-in end 220. The tab 110 on the opposite end of the cylindrical battery 100 near the plug-in end 220 passes through the first through hole 222 and is soldered to the corresponding first connection terminal 210. Further, the series structure includes a second through hole 230 and a second connection terminal 240. The second through hole 230 is opened in the middle of the circuit board 200. The two second connection terminals 240 are symmetrically arranged on both sides of the second through hole 230 and are electrically connected. Specifically, the two second connection terminals 240 are electrically connected through copper foil provided on the circuit board 200.

[0032] The tabs 110 on the opposite ends of the two cylindrical batteries 100 pass through the second through hole 230 and are welded to the corresponding second connecting terminals 240 respectively. The first through hole 222 corresponds to the first insulating pad 300. Both the first through hole 222 and the second through hole 230 are strip-shaped, and the length of both is greater than the width of the tab 110, so that the corresponding tabs 110 can pass through the first through hole 222 and the second through hole 230 respectively, improving the convenience of operation.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
