Therefore, the battery of the embodiment of the utility model occupies smaller space of the electronic equipment, and is convenient and quick to assemble.

In one possible implementation, the connection part 130 and the positioning part 120 are respectively located at opposite ends of the housing body 110 in the second direction.

In this way, the positions of the positioning portion 120 and the connecting portion 130 along the second direction are not only staggered, which is favorable for the positioning portion 120 and the connecting portion 130 to fully utilize the space of the electronic device in the second direction, but also the positioning portion 120 and the connecting portion 130 are respectively located at two opposite ends of the housing body 110 along the second direction, so that the positioning portion 120 and the connecting portion 130 can be symmetrically arranged along the diagonal line of the housing body 110, and are arranged between the two ends of the housing body 110 along the second direction relative to the positioning portion 120 and the connecting portion 130, the positioning portion 120 is arranged at one end of the housing body 110 along the second direction, and the connecting portion 130 is arranged at the other end of the housing body 110 along the second direction, so that a larger avoiding space is formed between the positioning portion 120 and the inner wall of the electronic device and between the connecting portion 130 and the inner wall of the electronic device, thereby facilitating the arrangement and installation of other electronic components.
