The present invention relates to a cell busbar fastening structure of a serial connection device for a battery module. The present invention comprises a base (10), a cover (20), a cell busbar (30) and a substrate (40). The base forms a busbar seating end (11) and a base side coupling end (16). The cover forms a cover side coupling end (26) coupled to a busbar pushing unit (21) and the base side coupling end. The busbar seating end seats at a fixing piece (31) of the cell busbar. A first and a second connecting pieces (36,37) penetrate a base penetration slit (15) of the base and protrudes out of the base in both ends of the fixing piece. A substrate seating unit (10") is formed along the center in the longitudinal direction of the base and makes the substrate seat thereon. A position guide protrusion (13) is formed at one end in the longitudinal direction of the busbar seating end, and a hooking hole (13') is formed at an end in the contrary direction. A movement preventing protrusion (34) being guided by the position guide protrusion is formed at one end of the fixing piece of the cell busbar, and a base hooking protrusion (33) being hooked at the hooking hole is formed at the other end of the fixing piece. The present invention has an advantage in fixing the cell busbar solidly at the busbar seating end. |
