when charging is needed, the charging current carrier size and the electrode switching-on sequence are selected according to the charged carrier, taking an electric vehicle as an example: selecting the number of the assembled elastic contact fingers or the number of the sub mounting seats 15 according to the size of the charging current carrier required by the electric vehicle; according to the connection sequence of the inner electrode 11, the elastic contact fingers are selectively assembled in the radial direction and the axial direction of the annular mounting seat 1, and after the preparation work is finished; the plug electrode is inserted into the receptacle electrode 31 to make an electrical connection, and during mating, the plug PE electrode is first brought into contact with the receptacle electrode 31 to make ground protection, then the plug DC +/-electrode is brought into contact with the receptacle electrode 31, and finally the plug CP electrode is brought into contact with the receptacle electrode 31. After the pairing is finished, the CP electrode of the plug is electrified, when the CP electrode is detected to be in contact with the socket electrode 31, the DC +/-electrode of the plug is electrified to carry out power output, and if the CP electrode is detected not to be in contact with the socket electrode 31, the DC +/-electrode of the plug is not electrified, so that the electric vehicle is charged.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
