[0025] The protective box assembly 2 includes a protective frame 21, and the plug body 1 is located inside the protective frame 21. The opening and closing assembly 3 includes a fixed plate assembly 31 and a slide rail 32. The slide rail 32 is fixedly connected to the right side of the protective frame 21. Two baffles 33 are slidably connected between the slide rails 32, and the two baffles 33 can open and close. The fixed plate assembly 31 is fixed to the outside of the wire 11. Push rods 34 are rotatably connected to the front and back of the fixed plate assembly 31. The other ends of the two push rods 34 are rotatably connected to one side of the two baffles 33 respectively. A return spring 35 is provided between the fixed plate assembly 31 and the protective frame 21, and the return spring 35 is sleeved on the outside of the wire 11. Sealing gaskets 38 are pasted on the opposite sides of the two baffles 33. Two L-shaped hanging rods 36 are fixedly connected to the right side of the fixed plate assembly 31. A stop block 37 for cooperating with the L-shaped hanging rod 36 is fixedly connected to the right side of the two baffles 33. The stop block 37 is a right trapezoid with its inclined surface facing the L-shaped hanging rod 36.

[0026] An opening and closing component 3 is provided at the opening of the protective frame 21. When using the plug, the protective frame 21 is pushed to extend the plug body 1 for plugging and charging. After use, the plug body 1 automatically retracts into the protective frame 21, and the protective frame 21 is sealed as a whole by two baffles 33, thereby effectively avoiding the risk of water ingress and improving the practicality of the device.

[0027] The second embodiment differs from the first embodiment in that the fixing plate assembly 31 includes an upper pressure plate 311 and a lower pressure plate 312. An arc-shaped groove is provided on the opposite side of the upper pressure plate 311 and the lower pressure plate 312.
