Integrated busbar with buffer structure

The utility model relates to the technical field of power and energy storage battery assemblies, in particular to an integrated busbar with a buffer structure, which comprises a nickel sheet, an isolation frame, a busbar and a flexible circuit board, the busbar and the flexible circuit board are respectively arranged on the isolation frame, and the flexible circuit board is electrically connected with the busbar through the nickel sheet. The integrated busbar further comprises a mounting hole penetrating through the isolation frame and an elastic structure arranged on the isolation frame, and the free end of the elastic structure protrudes to the position below the mounting hole. The busbar cover is arranged above the mounting hole; the elastic structure and the isolation frame are made of insulating materials. The elastic structure is used for separating the busbar and the battery, so that the busbar and the battery can be conducted in sequence in the welding process, the problems that terminals of the busba
