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. The live wire plug and the zero line plug of the three-phase plug are respectively inserted into the corresponding conductive clamping pieces, and the grounding plug is inserted into the top socket at the upper end and is connected with the grounding contact piece. When the live wire plug and the zero wire plug are inserted into the conductive clamping pieces (the clamping grooves formed by the conductive clamping piece grooves), the two conductive pieces of the conductive clamping pieces can be extruded to move outwards, and the conductive clamping pieces are clamped with the lock tongues on the conductive clamping pieces under the action of self-existing extrusion force, so that the self-locking of the plug is realized.
