Abstract: A terminal having a stamping elastic sheet structure, including a mounting base (1) and an outer elastic sheet structure (2). An end of the outer elastic sheet structure (2) is connected to an end of the mounting base (1). The mounting base (1) and the outer elastic sheet structure (2) are formed separately, and the outer elastic sheet structure (2) is formed by stamping. The terminal having the stamping elastic sheet structure is formed by assembling a stamping elastic sheet and a mounting base that are separately machined and manufactured, instead of integral machining, so as to greatly reduce the cost of the terminal, reduce the machining time, ensure a sufficient contact between the elastic sheet and a conductive portion of a mating terminal, and meet the mechanical demand and the temperature rise requirement of a charging system.
