[0101] The elastic element 313 is connected between the movable part 312 and the mounting part 314, that is, one end (e.g., the bottom end) of the elastic element 313 is connected to the movable part 312, and the other end (e.g., the top end) of the elastic element 313 is connected to the mounting part 314.

In some embodiments of the present invention, the metal shielding plate 37 is welded and fixed to the extension portion 362. When the metal shielding plate 37 covers the extension portion 362, the metal shielding plate 37 and the extension portion 362 together form a 360° surrounding shielding structure, which is beneficial to further improve the shielding effect.

[0115] The metal shielding surround 36 is configured to be at least partially inserted into the receiving space 201 of the support frame assembly 100, and the metal shielding surround 36 abuts against the first abutting spring arm 21212 and the second abutting spring arm 22212 of the support frame assembly 100 to increase the insertion and extraction force and improve the shielding effect.
