MOUNTING BASE, BATTERY, AND ELECTRICAL DEVICE

The present application provides a mounting base, a battery and a power consuming device, which relate to the technical field of batteries. The mounting base is configured to be connected to an end plate and an output electrode, and an insulating member is provided on one side of the end plate and configured to insulate the end plate from a battery cell. The mounting base includes a main body provided with a flow guiding groove on the side facing the insulating member. The flow guiding groove is configured to prevent an electrical connection between the output electrode and the end plate by means of a liquid between the main body and the insulating member. The provision of the flow guiding groove on the main body increases the distance between the main body and the insulating member at the position where the flow guiding groove is provided, and a liquid film is not prone to being formed between this position and the insulating member, so that it is not likely to form a continuous liquid film between the main body and the insulating member, thereby effectively reducing the risk of electrical connection between the output electrode and the end plate by means of the liquid between the main body and the insulating member, which could otherwise cause failure of the insulation protection of the output electrode from the mounting base, the battery is less prone to short circuiting, and the safety of the battery is improved.
