The fixing plate 321 is fixed to the upper surface of the base portion 311, and the fixing plate 321 is further provided with a bump 3211 to be in contact with the socket shielding case 33 surrounding the socket insulating body 31, thereby forming a ground loop. The elastic arm 322 extends forward from the frame portion 323 to surround the step portion 313. As shown in the eighth to ninth drawings, when the mated plug connector 400 is inserted, the elastic arm 322 is in contact with the inner surface of the front end 411 of the plug shielding case 41 of the plug connector 400, thereby preventing electromagnetic interference, Protection against radio frequency interference. The plug shielding case 41 protrudes forward from the plug insulating body 415, and the front end 411 of the plug shielding case 41 is sandwiched between the socket grounding member 32 and the socket shielding case 33. The socket grounding member 32 further includes a hook portion 324 that is secured within the fixed slot 314 of the base portion 311, as shown in the sixth figure. Shown from the fifth to seventh figures As shown in the assembly process of the socket grounding member 32, the socket grounding member 32 is assembled into the socket insulating body 31 in the front-rear direction, and the butting tongue 312 passes through the middle of the frame portion 323. First, the hook portion 324 is first inserted and fixed in the fixing slit 314. The fixing plate 321 passes over the upper surface of the base portion 311, and then pushes the frame portion 323 backward until the frame portion 323 abuts against the front end surface of the base portion 311, at which time the fixing plate 321 is also completely attached to the upper surface of the base portion 311, and the fixing plate The inner hook edge 3212 of the rear end of the 321 is hooked on the rear end surface of the base portion 311 (the ninth diagram is clearly shown), thereby stably fixing the fixing plate 321 to the base portion 311.

11 to 11 are a modified structure of a plug connector. The internal circuit board 42 in the plug connector 400a has a grounding strip 421 which is exposed on the front end surface of the inner circuit board 42 and can be latched. The rear edge of the member 43 is in contact to complete the electrical connection. During the docking process, the head hook structure of the locking member 43 is engaged with the side edge latching notch of the shielding plate 37 of the socket connector in the sixth figure, and the shielding plate 37 has the circuit board pin 372, thereby forming Ground loop.

The twelfth to thirteenth drawings show the structure of the plug connector 400b of the fourth embodiment, which includes the plug insulating body 44, the plug grounding member 45, and the plug shielding case 46. The plug insulating body 44 is provided with a docking slot, and the plug terminals are arranged in the docking slot. The plug grounding member 45 has an annular structure, which is fixed on the outer side of the front end of the plug insulating body 44.
