Inside the slots 142 are The inclined guiding surface 143 has a stopper 151 extending downward from the bottom surface 15 of the base 10 of the insulating body 1 . In this embodiment, a plurality of conductive terminals 2 are injection-molded with the insulating body 1, the terminal holding part (not shown) is fixed in the insulating body 1, and the contact part 21 is accommodated in the terminal receiving groove 111 (see FIG. 1 ). shown), and the pin portion 22 extends backward out of the insulating body 1 for soldering with the circuit board.

The shielding housing 3 includes a first housing 31 and a second housing 32. The first housing 31 includes a top wall 311 and first side walls 312 extending downward from both sides of the top wall 311. The first side wall 312 There are a pair of buckle parts 313 horizontally extending outward on both sides of its lower end edge. The buckle parts 313 are provided with buckle blocks 314 arranged oppositely. The first side wall 312 continues to extend forward from the lower part of its front edge and then vertically upwards A first buckling portion 315 is formed, and the first buckling portion 315 is provided with a blocking portion 316 extending vertically upwards. The blocking portion 316 is evenly spaced from the top wall 311 and the first side wall 312 to form a receiving space 317 , that is, the blocking portion 316 is suspended. The second housing 32 includes a bottom wall 321 and a second side wall 322 extending obliquely upwards from both sides of the bottom wall 321 respectively. The second side wall 322 has a wing 323 extending horizontally outward from the rear part of the second side wall 323. There are through holes, and the two ends of the wing 323 are provided with holding openings 324. The front end of the second side wall 322 extends upwards with a second holding portion 325, and a part of the second holding portion 325 is cut off near the upper part to form a In the opening 326 , the second locking portion 325 forms an L-shaped blocking portion 327 at the opening 326 , and the forming process of the blocking portion 327 will be described below.

First, the second housing 32 is assembled upwards from the bottom surface 15 of the base 10 of the insulating body 1 holding the conductive terminals 2, so that the abutting portion 328 extending from the rear end of the bottom wall 321 is against the rear end surface 13 of the insulating body 1, and then Assemble the first shell 31 downward from the top surface 14 of the base 10 of the insulating body 1, so that the buckle block 314 on the first shell 31 is correspondingly locked with the holding opening 324 on the second shell 32, so as to cover Covering the insulating body 1 (as shown in FIG. 2 ), and the buckle portion 313 and the wing portion 323 are correspondingly locked and then welded to the circuit board (not shown). At this time, the interference parts 152, 161 provided on the bottom surface 15 and the side surface 16 of the base 10 of the insulating body 1 interfere with the inner wall surface of the shielding case 3 and are fixed with the shielding case 3, and the top surface 14 and the bottom surface 15 of the base 10 of the insulating body 1 The extended stoppers 141, 151 respectively resist the notch 318 at the rear end of the top wall 311 of the first housing 31 and the rear end edge of the bottom wall 321 of the second housing 32, so as to prevent the insulating body 1 from excessively entering the shielding housing 3. The two ends of the buckling piece 319 between the two gaps 318 are held in the slot 142 by the guidance of the guide surface 143 (as shown in FIG. 2 ). 1 can prevent the insulating body 1 from moving backward and detaching from the shielding case 3 . In this way, after the first shell 31 and the second shell 32 are buckled correspondingly, the insulating body 1 holding the conductive terminal 2 can be stably held, and a receiving cavity 4 for a docking connector can be formed (see FIG. 1), the front end surface 12 of the insulating body 1 and the tongue plate 11 extend into the accommodating cavity 4 .

Then, the upper part of the second holding part 325 of the second casing 32 is bent inwardly from the opening 326 to be correspondingly accommodated in the receiving space 317. At this time, the blocking part 316 of the first holding part 315 is received in the opening 326. , one side of the stopper 316 is against the stopper 327, and the other side is against the inner wall surface of the second buckling part 325 (as shown in FIG. 1 ), so that the first housing 31 and the second housing 32 After buckling, a frame opening is formed at the opening of the receiving cavity 4 (as shown in FIG. 1 ), and the first buckling part 315 and the second buckling part 325 are located on the first sides of the first and second housings 31 and 32 respectively. The wall 312 and the second side wall 322 are adjacent to the frame opening. The firm buckling between the first buckling part 315 and the second buckling part 325 can prevent the frequent plugging and unplugging of the docking connector from causing relative movement and separation between the first and second housings 31 and 32, which can prevent the shielding The frame opening of the housing 3 is deformed to enhance the strength of the frame opening. In other embodiments, the positions of the first buckling part 315 and the second buckling part 325 can also be exchanged, that is, the first buckling part 315 is arranged on the second housing 32, and the second buckling part 325 is disposed at a corresponding position of the first housing 31 .
