CONNECTION ASSEMBLY, BATTERY MODULE, BATTERY PACK, DEVICE, AND MANUFACTURING METHOD

An embodiment of this application provides a connecting assembly, a battery module, a battery pack, a device, and a manufacturing method. The connecting assembly includes an insulation board and a busbar. The insulation board includes a hollow portion, a first side, and a second side. The busbar includes a first busbar and a second busbar. The first busbar is disposed on the first side of the insulation board. The second busbar is disposed from the second side into the hollow portion of the insulation board. The battery module includes a battery cell and a module frame. The battery cell is accommodated in the module frame. The battery module further includes a connecting assembly. The connecting assembly is connected to an electrode lead of the battery cell by the busbar. The battery pack includes the battery module. A device using a battery cell as a power supply includes: a power source configured to provide a driving force for the device; and a battery module configured to provide electrical energy to the power source. This application mitigates the problem that the busbar is hardly shockproof and is likely to shake.
