At least part of the locking pieces 22 is located in the mating space 101, and is used to abut against the plug connector 200 inserted into the mating space 101. By arranging the locking pieces 22 on the first metal shell 2, not only the holding force of the locking pieces 22 is enhanced, so that the connection between the socket connector 100 and the plug connector 200 is more stable, but also the grounding shielding performance of the socket connector 100 is improved.

[0049] The plug connector 200 includes an insulating body 210, a second conductive terminal module 220 fixed in the insulating body 210, and an outer shell 230 covering the outside of the insulating body 210. When the plug connector 200 is mated with the socket connector 100, at least part of the insulating body 210, the second conductive terminal module 220, and at least part of the outer shell 230 are inserted into the mating space 101, and two locking pieces 22 are respectively abutted against the outer shell 230 in the width direction WW, so as to improve the holding force of the locking pieces 22 and also improve the shielding and grounding effect of the plug connector 200.

[0050] Please refer to Figure 4 , Figures 8 to 10 The main body 21 also has a thickness direction TT perpendicular to both the length direction and the width direction WW. The main body 21 has two first edges 211 arranged opposite to each other in the width direction WW. Preferably, the two first edges 211 extend along the docking direction M, and the two first edges 211 are parallel to each other. The main body 21 also includes two second edges 213 arranged opposite to each other in the length direction. The two second edges extend along the width direction WW, and the two second edges 213 are parallel to each other.

The first side 2121, the second side 2122, and the extension line of the first edge 211 form a triangular structure, and the locking piece 22 is disposed on the first side 2121, so that when the plug connector 200 enters the mating space 101, the outer shell 230 can abut against the locking piece 22, thereby improving the shielding and grounding performance. Preferably, the angle between the first side 2121 and the extension line of the first edge 211 is an acute angle.

When the first metal shell 2 covers the bottom of the insulating seat 1, the two first edges 211 of the first metal shell 2 fit with the bottom of the two side walls 112 of the insulating seat 1, so as to provide better support for the locking piece 22, thereby improving the holding force of the locking piece 22 and preventing the locking piece 22 from being deformed. At the same time, when the plug connector 200 is docked with the socket connector 100, the two locking pieces 22 are in contact with the outer shell 230 in the width direction WW at the same time, so that the central axis of the plug connector 200 can be close to the central axis of the socket connector 100 to avoid poor docking between the plug connector 200 and the socket connector 100.
