When the pins of the plug shell are connected to the external socket, the cable shell can be turned according to the actual use environment, so that the wires connected to the cable shell are in a position that is easy to accommodate and pass through, thereby greatly increasing the convenience of using the plug.
[0023] Furthermore, the conductive component 8 includes an insulating base 81 and a plurality of conductive spring sheets 82 elastically deformably connected to the insulating base 81, the plurality of conductive spring sheets 82 are arranged at intervals along the circumference, the connecting shaft 4 is inserted between the plurality of conductive spring sheets 82, the conductive part 6 includes a first conductive part 61, a second conductive part 62 and a third conductive part 63, the plurality of conductive spring sheets 82 are respectively and one by one in contact with the first conductive part 61, the second conductive part 62 and the third conductive part 63, and a limiting ring 83 is provided in the mounting groove 7 to drive the conductive spring sheet 82 to press against the conductive part 6.
[0024] Specifically, the first conductive part, the second conductive part and the third conductive part on the connecting shaft are respectively electrically connected to the corresponding pins through wires. When the connecting shaft and the cable housing rotate and cooperate, the connecting shaft is located between the plurality of conductive springs, and the first conductive part, the second conductive part and the third conductive part on the connecting shaft are respectively in contact with the plurality of conductive springs to achieve electrical connection between the two, and the plurality of conductive springs are respectively electrically connected to the live wire, the neutral wire and the ground wire of the power supply cable one by one, and then the conductive springs are fixed and limited by a limiting ring, so that the conductive springs remain tightly against the conductive part, so as to effectively avoid power outages caused by poor contact and affect normal use.
[0025] Furthermore, the connecting shaft 4 has an annular cavity 64, and a plurality of ribs 65 are evenly distributed along the circumference of the annular cavity 64, and the annular cavity 64 is divided into a plurality of wiring areas by the plurality of ribs 65. The first conductive part 61, the second conductive part 62 and the third conductive part 63 correspond to the plurality of wiring areas respectively, and are electrically connected to different pins 3 through wires. A plurality of openings 66 connected to the annular cavity 64 are provided at intervals along the axial direction on the peripheral side of the connecting shaft 4, and the first conductive part 61, the second conductive part 62 and the third conductive part 63 are arranged in the plurality of openings 66 in a one-to-one correspondence.
[0026] Furthermore, the limit ring 83 is connected to the mounting groove 7 by threads, and a plurality of conductive springs 82 are located at the inner ring of the limit ring 83.
