BATTERY TOP COVER AND BATTERY

Abstract

A battery top cover and a battery are provided. The battery top cover includes at least one cover plate and a conduction assembly. The cover plate has a mounting hole extending in a direction the thickness of the cover plate from an inner to an outer side, and a first positioning portion is provided on the outer side of the cover plate. The conduction assembly includes a terminal, a pressure plate, and a first seal. The terminal includes a terminal body and an internal connection portion. The terminal body is inserted into the mounting hole, and the internal connection portion is fixedly arranged on the inner side of the terminal body. The internal connection portion is configured to have a larger cross-section than the terminal body. The pressure plate is fixedly arranged on the outer side of the terminal body.The first seal is arranged between the pressure plate and the cover plate to separate them. The first seal has a first through hole extending in the direction of the seal's thickness, from an inner to an outer side, and the terminal body passes through this first through hole. A first positioning groove is provided on the inner side of the first seal, which is configured to cooperate with the first positioning element to firmly compress the first seal onto the cover plate via the pressure plate.
