An auto-aligning and connecting structure used to connect and align an electronic device and an accessory, wherein a plurality of first magnetic bodies are disposed on a first surface of the electrical device and a plurality of second magnetic bodies are disposed on a second surface of the accessory. The magnetic pole of the first magnetic bodies and the second magnetic bodies are appropriately arranged so the first magnetic bodies and the second magnetic bodies can attract each other when the first surface and the second surface approach each other. Then, the electronic device and the accessories are connected to each other when the first surface and the second surface connect.
