TAB LIMITING SHEET, TOP COVER ASSEMBLY, AND BATTERY

A tab limiting sheet (1), a top cover assembly (3), and a battery are provided. The tab limiting sheet (1) includes a first mounting part (11), a connecting assembly (12), and a second mounting part (16). The connecting assembly (12) includes an elastic element (121) and a first support element (122). The elastic element (121) is connected between the first mounting part (11) and the second mounting part (16). The first support element (122) includes a first supporting part (1221) connected with the first mounting part (11) and the second mounting part (16) connected with the second mounting part (16). When the elastic element (121) is in a natural state, the first supporting part (1221) and the second supporting part (1222) are spaced. When the elastic element (121) is squeezed to a maximum deformation state, the first supporting part (1221) is tight.
