Positioning posts 13 extend downward from the bottoms of both left and right sides of the base 11 to facilitate positioning and installation with an external circuit board, making the installation more stable and reliable.

[0038] The shielding shell 20 is covered on the outside of the insulating body 10, and the tongue plate 12 is suspended in the shielding shell 20. Specifically, the shielding shell 20 includes an inner shell 21 and an outer shell 22. The inner shell 21 is a stretched shell and is located around the outer periphery of the tongue plate 12. The rear end of the inner shell 21 is sealed and connected to the front end of the base 11. The outer shell 22 is a stamped shell. The outer shell 22 includes an integrally formed covering portion 221 and a covering portion 222. The covering portion 221 completely covers the outer peripheral side of the inner shell 21, so that the structure is effectively enhanced. The left and right sides of the covering portion 221 are punched and bent to extend a first fixed foot 201. The covering portion 222 covers the base 11. The left and right sides of the covering portion 222 extend a second fixed foot 202.

[0039] In this embodiment, the first fixing leg 201 is L-shaped to facilitate soldering and securing to an external circuit board. The second fixing leg 202 extends vertically downward to facilitate insertion and soldering to the external circuit board. The inner housing 21 is concave on the outside and convex on the inside, forming bumps 211 on the upper and lower inner walls of the inner housing to enhance the insertion and removal force of the product. The covering portion 222 includes a top plate 2221 and a back plate 2222. The top plate 2221 integrally extends backward from the rear side of the covering portion 221 and covers the top of the base 11. The two ends of the top plate 2222 are bent downward to form two side plates 2223, which respectively cover the left and right side surfaces of the base 11. The back plate 2222 integrally extends downward from the rear side of the top plate 2221 and covers the rear side of the base 11. The left and right sides of the back plate 2222 are bent forward to form two connecting plates 2224, which are respectively fastened and fixed to the two side plates 2223. This simple structure better covers the base 11, thereby enhancing the overall structure of the product. The second fixing leg 202 extends downward from the side plate 2223. Furthermore, the connecting plate 2224 is provided with a buckle hole 203, and the outer side of the side plate 2223 is provided with a protruding buckle 204. The protruding buckle 204 engages with the buckle hole 203 to secure the structure, further strengthening the structure. Furthermore, the front opening of the inner shell 21 is formed with an annular flange 212. The annular flange 212 is located in front of the front end surface of the covering portion 221 to enhance the structural strength of the front opening of the shielding shell 20.

The plurality of second contact portions 41 are exposed on the lower surface of the tongue plate 12, and the plurality of second soldering portions 42 extend outside the base 11. The middle clip 50 is located between the upper row of terminals 30 and the lower row of terminals 40. In this embodiment, the plurality of first soldering portions 32 are arranged in a row and extend horizontally and rearwardly to facilitate soldering to an external circuit board. The plurality of second soldering portions 42 are arranged in two rows, both extending vertically downward. Both rows of second soldering portions 42 are located in front of the plurality of first soldering portions 32 and are offset left and right to facilitate soldering to an external circuit board.

[0041] During use, the first fixing foot 201, the second fixing foot 202, the multiple first welding parts 32 and the multiple second welding parts 42 are all dipped in solder paste, and then the positioning column 13 is used to position the product on the external circuit board. After positioning, the first fixing foot 201 and the multiple first welding parts 32 are respectively attached to the corresponding pads of the external circuit board, and the second fixing foot 202 and the multiple second welding parts 42 are respectively inserted into the corresponding solder holes of the external circuit board. Then, the product and the external circuit board are reflowed so that the first fixing foot 201, the second fixing foot 202, the multiple first welding parts 32 and the multiple second welding parts 42 are all welded to the external circuit board. The welding structure is very stable, and has high stability and reliability.

[0042] The design focus of this utility model is that the shielding shell in this product is composed of an inner shell and an outer shell. The inner shell is a stretched shell. At the same time, the covering part is used to completely cover the outer peripheral side of the inner shell, and the covering part is used to cover the base to achieve a double-layer structure, so as to effectively enhance the structural strength of the product and avoid deformation and damage.
