The docking shielding shell 21 is disposed on a docking colloid 22, and the plugging shielding shell 31 is disposed on a plugging colloid 32.
The docking colloid 22 is provided with a plurality of docking terminals 221, and the plugging colloid 32 is provided with a plurality of plugging terminals 321 correspondingly combined with the docking terminals 221.
The docking shielding case 21 has a plurality of docking housing coupling portions 213, the docking colloid 22 has a plurality of docking colloid coupling portions 222 coupled to the docking housing coupling portions 213, and the docking housing coupling portions 213 are connected to the docking shielding portions 211.
