An outer socket 9 shaped like a Chinese character 'pin' is arranged on the end face of one end of the socket shell 1; the socket sleeve 2 is provided with a triangle inner socket 10 corresponding to the triangle outer socket 9; the conductive clip 6 corresponds to the bottom socket position of the triangular inner socket 10.

The other end of the socket shell 1 is provided with an electric wire 11, and a live wire and a zero wire in the electric wire 11 are respectively connected with the tail ends of the two conductive clamping pieces 6.

And a grounding contact piece is arranged in the top socket of the triangular inner socket 10 and is connected with a grounding wire of the electric wire 11.

The socket at the upper end of the inner socket is internally provided with a grounding contact piece, and the grounding contact piece is connected with a grounding wire in the wire.

The plug is provided with a lock hole matched with the lock tongue.

The utility model discloses a locking process: the three-phase plug is inserted into the delta-shaped outer socket and the delta-shaped inner socket in sequence and then enters the inside of the socket sleeve.
