Abstract: A power battery pack (100) is provided. The power battery pack (100) includes a case (10), a high-voltage connector (30) and a limiting frame (40) disposed in the case (10). The high-voltage connector (30) includes a base (31). A first surface (3101) of the base (31) faces to the top wall of the case (10). The limiting frame (40) is attached to the sidewall of the case (10). The limiting frame (40) is at least connected to a second surface (3102) of the base (31) to limit the base (31). By adding a limiting frame (40) inside the case (10), the limiting frame (40) limits the high-voltage connector (30) in the direction of the high-voltage connector (30) acted by the external force, thereby avoiding the loosening of the connection between the high-voltage connector (30) and other devices due to shaking.

Abstract: Provided is a top cover structure. The top cover structure includes a top cover and a pole assembly. The top cover includes a body and an outer protrusion portion. The outer protrusion portion is ringed at the edge of the body and protrudes in a direction facing away from a cell. An end of the outer protrusion portion is provided with a welding portion. The welding portion is welded to a housing of a battery. The body is formed with an assembly hole. The pole assembly is configured to seal the assembly hole. The welding portion is disposed away from the battery cell, that is, the distance between the welding portion and the internal component of the battery is increased. In this manner, it is possible to prevent welding heat from being transferred to the inside of the battery, thereby avoiding damage to the internal component. Thus, the sealing property between the top cover structure and the housing is ensured, and at the same time, the quality of the battery is ensured. A battery is also provided. The battery includes a housing and the preceding top cover structure. The housing includes a port portion. An end of the port portion is welded to a welding portion along a circumference of the welding portion.
