摘要： The present application provides a bracket and a cell contact system assembly. The bracket includes a bracket body, an elastic member and a position-limiting member. A fixed end of the elastic member and a fixed end of the position-limiting member are assembled on the bracket body. The position-limiting member, the elastic member and the bracket body enclose to define a position-limiting space. An end of the elastic member away from the fixed end of the elastic member is a free end. An end of the position-limiting member away from the fixed end of the position-limiting member is a position-limiting end. A guiding opening defined between the free end of the elastic member and the position-limiting end of the position-limiting member is communicated with the position-limiting space. The guiding opening has a size being adjusted by changing a degree of deformation of the free end of the elastic member.

摘要： 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.
