Battery cover and battery assembly

Abstract

The cap assembly consists of a bare aluminum plate (1), battery terminal (2), compression block (3), upper plastic part (4) and sealing part (5). The battery terminal (2) sequentially passes through the through hole in the bare aluminum plate (1), the through hole in the upper plastic part (4) and the through hole in the compression block (3). The upper plastic part (4) is clamped between the bare aluminum plate (1) and the compression block (3). The sealing part (5) is fitted into the battery terminal (2), and the sealing part (5) includes the tubular part (51). The cutting ring (511) is arranged in a circle at the first end of the tubular part (51) along the axis of the tubular part (51), and the cutting ring (511) is positioned between the first end of the tubular part (51) and the pressing block (3). The stiffness of the cutting ring (511) is greater than the stiffness of the tubular part (51). The cutting ring (511) rests against the pressing block (3). The tubular part (51) is partially clamped between the battery terminal (2) and the inner wall of the through hole of the plastic part on (4), and partially clamped between the battery terminal (2) and the inner wall of the through hole of the bare aluminum plate (1). The useful solution also refers to the battery.
