Further, the thin portion 442 is a groove structure, and the groove structure may be disposed as a shallow groove 442a structure on two opposite surfaces of the shielding plate 44, or a through groove structure penetrating through two opposite surfaces of the shielding plate 44. . When the shielding plate 44 is injection molded by the insulating material into the middle shielding module 413, the shallow groove 442a is filled with the insulating material. The thin portion 442 has a first surface 4421 facing rearward, a second surface 4422 facing forward, and two third surfaces 4423 located on both lateral sides. Referring to the eighth to ninth drawings, after the insulating material is cooled, a part of the insulating material forming the butting tongue 413' (ie, the middle shielding module 413) is formed as a convex portion 4133 located in the thin portion, the protruding portion The thin portion is filled, and the first surface 4421 is pressed forward, and the second surface 4422 is pressed back, so that the butt tongue 413' and the shielding plate 44 can be effectively fixed in the front and rear direction. The third surface 4423 is pressed against the projection in the lateral direction to stably fix the abutting tongue 413' and the shielding plate 44 in the lateral direction. When the thin section is a through-groove structure, the front edge 443 is connected to the main body of the shielding plate 44 through the neck 449. The other thin-shaped region 446 is a shallow groove structure disposed on two opposite surfaces of the shielding plate, which may also be used for filling the insulating material forming the abutting tongue. The groove structure disposed at the front end of the shielding plate 44 plays a major role in fixing the butt tongue, and in particular, the front end of the shielding plate is easily damaged by the impact of the docked plug connector, and the groove structure at the rear is For the auxiliary function.
