[0030] The socket assembly 200 includes a socket 201, a plug 101 and a clamping slot 204. The inner side of the socket 201 is provided with a plugging slot 202, and the top of the plugging slot 202 is provided with a clamping slot 204. The plug 101 is plugged into the plugging slot 202, and the elastic clamping plate 103 is frictionally connected with the clamping slot 204.

[0031] The outer side of the socket assembly 200 is covered with a shielding assembly 300, and the shielding assembly 300 includes a shielding tube 301, and the shielding tube 301 is slidably connected to the socket 201, and the shielding tube 301 is a three-layer structure with copper plates wrapped by aluminum plates on both sides of the outer layer.

[0032] The shielding assembly 300 further includes a connecting ring 302, a wrapping sleeve 303, an elastic rope 304 and a connecting rod 305. The connecting ring 302 is provided at one end of the shielding cylinder 301. Two elastic ropes 304 and two connecting rods 305 form an annular structure. The elastic rope 304 is made of elastic material, and the elastic material includes a rubber band. Both ends of each connecting rod 305 are respectively connected to the end of an elastic rope 304. One end of the wrapping sleeve 303 away from the connecting ring 302 is connected to one side of the annular structure.

[0033] The wrapping sleeve 303 is a rubber membrane with cross-woven metal wires installed inside. The metal wires are made of copper and can shield electromagnetic.

[0034] The bottom end of the plug 101 is provided with a pin 102, and the inner bottom wall of the plug 101 is provided with a pin 203, and the pin 203 is movably attached to the pin 102;

By controlling the connecting rods 307 on both sides of the shielding assembly 300, the elastic rope 304 and the connecting rod 305 are pulled to form a ring structure through the socket 201 and arrive at the plug 101. After placement, the elasticity of the elastic rope 304 causes the opening of the wrapping sleeve 303 to shrink and close the opening of the shielding tube 301.
