Battery top cover and battery

Abstract

The useful solution proposes a battery cover mechanism for the power battery and the power battery. The power battery cover mechanism includes a cover plate (1), battery terminals (2), and a plastic part on top (3). The cover plate (1) is equipped with two battery terminal holes (11) spaced apart, and two battery terminals (2) pass through the two corresponding battery terminal holes (11). The battery terminal groove (21) is created along the circumference on the outer wall of the battery terminal (2), and the groove (210) is pressed at the bottom of the battery terminal groove (21). The two plastic parts (3) are fitted onto the two corresponding battery terminals (2). The plastic part (3) extends into the battery terminal groove (21), the inner wall of the plastic part (3) is in contact with the groove (210), and the bottom of the plastic part (3) is in contact with the cover plate (1).
