[0047] First, the button battery 3 is placed between the clamping end 122 of the first electrode column 12 and the second clamping end 222 of the second electrode column 22. Then, by rotating the female connector body 11 and the male connector body 21, the step ring 211 is extended into the cavity and matched with the female connector body 11, so that the first magnetic body 13 and the second magnetic body 23 fasten the male connector 2 and the female connector 1 by magnetic connection, and limit the position by the base 212, so that the first electrode column 12 and the second electrode column 22 clamp the button battery 3.
