the charging plug is configured to be connected to a charging pile through a charging wire to serve as a charging plug, the charging plug can be inserted into a charging slot, a mounting groove is formed in the front end face of the charging plug, an inserting column is arranged in the middle of the bottom surface of the mounting groove, the extending direction of the inserting column corresponds to the depth of the mounting groove, an inner plug is arranged at the front end of the inserting column and is used for being in contact fit with an N-end contact at the bottom of the mounting groove for charging,

the rear end of the inserting column adjacent to the bottom of the mounting groove is fixedly provided with a fixed hinge seat, the annular array on the fixed hinge seat is provided with three outer plugs which are in hinge fit with the fixed hinge seat, the outer plugs are rod-shaped, the outer ends of the outer plugs are provided with alternating current contacts which are respectively contacted with the contact pieces to realize charging,

sliding fit has the articulated seat of sliding on inserting the post, be equipped with sharp coil spring between articulated seat of sliding and the articulated seat of fixed, the spring cup joints on inserting the post, the spring has the elastic force that makes the articulated seat of sliding push away from the articulated seat of fixed, insert the post and can insert the configuration inslot, the articulated seat of sliding can not insert the configuration inslot, the articulated seat of sliding can slide around its length direction along inserting the post, annular array has three rather than articulated complex regulation pole on the articulated seat of sliding, the outer end of adjusting the pole articulates the middle part at the outer plug, it is equipped with the mouth of stepping down that is used for making outer plug to run through to correspond outer plug position on the lateral wall of mounting groove, adjust the articulated part of pole and outer plug and can wear out from stepping down the mouth and expose the outside at charging plug.

2. The leakproof charging port for the electric vehicle as claimed in claim 1, wherein the bottom of the disposition slot is disposed with a CC contact and/or a C contact.

3. The electric vehicle leakage-proof charging port according to claim 1, wherein a CC hole and/or a CP hole are integrally formed at a front end of the inner plug.

4. The electric leakage preventing charging port for the electric vehicle as claimed in claim 1, wherein the mounting groove is a cylindrical groove.

5. The electric leakage preventing charging port of the electric vehicle as claimed in claim 1, wherein the annular array on the fixed hinge base has three first U-shaped hinge plates, the outer plug is hinged on the first U-shaped hinge plates, and the outer end of the outer plug is respectively provided with three connection contacts of L1, L2 and L3 for ac power;

the annular array on the sliding hinge seat is provided with three second U-shaped hinge plates, and the adjusting rod is hinged to the second U-shaped hinge plates.

6. The electric vehicle leakage-proof charging port according to claim 1, wherein when the charging plug is in a standby state, the spring pushes the sliding hinge seat away from the fixed hinge seat, and the outer plug is located in the mounting groove;

when the charging plug is inserted into the charging slot and the inserting column is inserted into the bottom of the configuration slot, the front end face of the pushing column is matched with the sliding hinge seat to enable the sliding hinge seat to be close to the fixed hinge seat, and at the moment, the outer plug penetrates through the position-giving opening and the strip-shaped socket in sequence and contacts the contact piece.
