[0039] As shown in Figure 3 and 7 The lock assembly 201 comprises a lock block 210 for locking the socket 1 and the plug 2, the lock block 210 is rotatably provided with a rotating shaft 211 for rotating the lock block 210, the rotating shaft 211 is fixedly connected with a rotating shaft support block 214 at both ends for supporting the rotating shaft 211. The lock block 210 is fixedly connected with a spring 212 between the plug shell 204 for resetting the lock block 210 after pressing and unlocking, the lock block 210 is provided with an anti-skid pattern 213 for anti-skid. The socket shell 101 is provided with a lock 209 for locking with the lock block 210.

[0040] As shown in Figures 8-11 The shielding sleeve 3 is installed in the plug 2 for secondary electromagnetic shielding. The shielding sleeve 3 comprises a first shielding sleeve 301, the first shielding sleeve 301 is provided with a second shielding sleeve 302 on one side. The first shielding sleeve 310 is provided with a first connecting body 309, the first connecting body 309 is provided with a first connecting arm 305 to connect the connecting body 309 together, the first connecting body 309 is provided with a first limiting block 304 to limit the second connecting arm 303. The second shielding sleeve 302 is provided with a second connecting body 310, the second connecting body 310 is provided with a second connecting arm 303 for connecting the second connecting body 310.

[0041] As shown in Figures 8-11 The second shielding sleeve 302 is provided with a locking buckle 307 for fixing the shielding sleeve 3, the locking buckle 307 is provided with an unlocking block 308 for pulling out the locking buckle 307 from the locking groove 206 when disassembling the shielding sleeve 3, the unlocking block 308 is fixedly connected with one end of the first connecting arm 305.
