[0002] Polymer lithium - ion batteries are often applied to the mobile phone industry. They can have a relatively high power while having a small volume. However, when they are applied to other fields, it is not necessary to require them to be completely hidden in the device. When arranging and connecting polymer lithium - ion batteries, a direct attachment method is used to connect multiple batteries together and then they are wound and fixed with tape or the like to form a battery block. When multiple polymer lithium - ion batteries are connected in series, the disassembly and installation of the polymer lithium - ion battery pack and its outer shell are not convenient, and it is not convenient for personnel to electrically connect multiple power plugs when electrically connecting multiple polymer lithium - ion battery packs.

It is characterized in that a connection bracket is arranged on one side of the shell, and it also includes a plurality of T - shaped blocks and guide rails. A T - shaped groove is arranged inside the guide rail, and the T - shaped blocks on different shells are clamped with the T - shaped groove, so that a modular structure can be formed between multiple shells.

[0005] Further technical solution, the T - shaped blocks are arranged on the top and the rear side of the shell, and the guide rails are arranged on the bottom of the shell and the front side of the connection bracket.

[0006] Further technical solution, the T - shaped blocks and guide rails on the upper and lower sides of the shell are arranged oppositely.

[0007] Further technical solution, the guide rails and T - shaped blocks on the front and rear sides of the shell are arranged oppositely.

[0008] Further technical solution, a plurality of ventilation holes are arranged on the upper and lower sides of the shell.

[0009] Further technical solution, a perforation is arranged on the connection bracket, and sliding grooves are arranged on the front and rear sides of the perforation.

[0010] Further technical solution, it also includes a power plug. Two electric connection lines are arranged on one side of the power plug, and the electric connection lines are electrically connected with the polymer lithium - ion battery pack.

[0011] A further technical solution is that the power plug is snapped into the chute.

[0012] The beneficial effects of the present utility model are as follows:

[0013] First, by placing the polymer lithium-ion battery pack inside the housing, the ventilation holes play a role in heat dissipation.

[0014] Second, after placing the polymer lithium-ion battery pack inside the housing, multiple housings are spliced together to form a modular setting, which facilitates the disassembly and installation of the housing and the polymer lithium-ion battery pack.

[0015] Third, a connection bracket, a perforation, and a chute are provided to facilitate the plug-in installation of the power plug. Since the position of the power plug is limited and snapped, it is more convenient for personnel to electrically connect multiple power plugs when electrically connecting multiple polymer lithium-ion battery packs.
