Each charging positive terminal 22/25 and each charging negative terminal 23/24 are provided at the bottommost portion of the charging terminal 26.
The charging terminal 26 may be shaped as a cylinder, and the receiving groove 12 has a circular cross-section, and the cross-sectional area of the receiving groove 12 is larger than that of the cylinder.
Referring to fig. 2, when the cross section of the receiving groove 12 is circular, the positive charging ring 14 and the negative charging ring 13 are concentrically disposed with the center of the bottom wall as the center of the center, and the positive charging ring 14 is located inside the negative charging ring 13.
The receiving groove 12 may be a receiving groove having a cross-sectional area that gradually decreases in a direction from an opening portion thereof toward the bottom wall, that is, the receiving groove 12 has an inverted cone shape, see fig. 1 and 3.
