[0039] Please refer to Figures 1 to 5 As shown, it shows the specific structure of a preferred embodiment of the present invention, including an insulating body 10, a shielding shell 20, an upper row of terminals 30, a lower row of terminals 40 and a middle clip 50.

[0040] The insulating body 10 includes a base 11 and a tongue plate 12 extending forward from the base 11. In this embodiment, the insulating body 10 is composed of an upper insulating member 101, a lower insulating member 102, and an outer insulating member 103. The upper and lower insulating members 101 and 102 are stacked and fixed together and are both embedded and fixed within the outer insulating member 103. Furthermore, the front side of the base 11 is provided with two retaining grooves 111, one on each side. The rear side of the base 11 is provided with two retaining grooves 112, one on each side.

[0041] The shielding shell 20 is wrapped around the insulating body 10, and the tongue plate 12 is suspended within the shielding shell 20. In this embodiment, the shielding shell 20 is an iron shell formed by stamping. A front fixing leg 21 and a rear fixing leg 22 extend downward from both the left and right sides of the shielding shell 20. The front fixing leg 21 and the rear fixing leg 22 are arranged in a front-to-back arrangement to facilitate mounting and fixing to an external circuit board. The top of the shielding shell 20 is punched to form a spring clip 23, which extends inwardly into the shielding shell 20. Two spring clips 23 are provided on the left and right sides to increase insertion and removal force. Furthermore, the bottom of the shielding shell 20 is concave on the outside and convex on the inside, and a protrusion 24 is formed on the inner wall of the shielding shell 20. Two protrusions 24 are provided on the left and right sides to further enhance insertion and removal force. In addition, the top rear side of the shielding shell 20 is punched out to form a limiting portion 25 and a snap-fit piece 26. The limiting portion 25 is inserted into the limiting groove 111 from front to back to prevent the shielding shell 20 from moving backward relative to the insulating body 10. The snap-fit piece 26 is bent downward and snap-fitted into the snap-fit groove 112 to prevent the shielding shell 20 from moving forward relative to the insulating body 10, thereby ensuring a stable installation.

[0042] The upper row of terminals 30 is disposed on the insulating body 10 and includes an upper grounding terminal 301. The upper row of terminals 30 has a plurality of first contact portions 31 and a plurality of first welding portions 32. The plurality of first contact portions 31 are exposed on the upper surface of the tongue plate 12, and the plurality of first welding portions 32 extend outside the base 11. In this embodiment, the upper row of terminals 30 and the upper insulating member 101 are fixed together by insert molding, and the two upper grounding terminals 301 are symmetrically arranged on the left and right.

[0043] The lower row of terminals 40 is mounted on the insulating body 10 and includes a lower grounding terminal 401. The lower row of terminals 40 has multiple second contact portions 41 and multiple second soldering portions 42. The multiple second contact portions 41 are exposed on the lower surface of the tongue plate 12, while the multiple second soldering portions 42 extend outside the base 11. In this embodiment, the lower row of terminals 40 are fixedly joined to the lower insulating member 102 by insert molding. Two lower grounding terminals 401 are symmetrically arranged. The multiple first soldering portions 32 and the multiple second soldering portions 42 are arranged in a row and extend horizontally rearwardly from the bottom of the base 11 to facilitate soldering to an external circuit board.

[0044] The middle clip 50 is disposed on the insulating body 10, and is located between the upper row of terminals 30 and the lower row of terminals 40. A bump 51 is protruded from the middle clip 50. The middle clip 50 is fixed to the lower insulating member 102 by inlay molding. The bump 51 is in contact with and electrically connected to the upper grounding terminal 301 and / or the lower grounding terminal 401. In this embodiment, the middle clip 50 is made of a steel sheet. One surface of the middle clip 50 is concave and the other surface is convex to form the bump 51, which makes the connection with the insulating body 10 more stable. In addition, the bump 51 is formed by stamping, which is easy to manufacture. There are two bumps 51 symmetrically arranged on the left and right. The two bumps 51 are in contact with and electrically connected to the bottom surfaces of the two upper grounding terminals 301, respectively, making the contact connection more stable and reliable, and achieving a better anti-static effect. The front side of the middle clip 50 is provided with two first notches 52 and a second notch 53. The two first notches 52 are symmetrically arranged on the left and right sides. The second notch 53 is located between the two first notches 52. The width of the second notch 53 is greater than the width of the first notch 52. The second notch 53 and the two first notches 52 are all buried in the insulating body 10 to avoid the corresponding terminals and ensure that the middle clip 50 is firmly combined with the insulating body 10. The left and right sides of the front end of the middle clip 50 are provided with first slots 54. The two first slots 54 are buried in the insulating body 10, ensuring that the middle clip 50 is firmly combined with the insulating body 10. In addition, the middle part of the middle clip 50 is provided with a second slot 55. The second slot 55 extends horizontally and is buried in the insulating body 10, ensuring that the middle clip 50 is firmly combined with the insulating body 10. In addition, third slots 56 are formed on both left and right sides of the rear end of the middle clip 50 . The two third slots 56 are embedded in the insulating body 10 , so that the middle clip 50 and the insulating body 10 are firmly combined.

[0045] The assembly process of this embodiment is described in detail as follows:

[0046] First, the lower row of terminals 40 and the middle clip 50 are placed in an injection mold to form the lower insulating part 102, and the upper row of terminals 30 are placed in another injection mold to form the upper insulating part 101. Then, the upper insulating part 101 and the lower insulating part 102 are overlapped and placed together in another injection mold to form the outer insulating part 103. Finally, the shielding shell 20 is fitted and covered on the insulating body 10.

[0047] The design focus of the utility model is that a convex bump is provided on the middle clip, and the convex bump is used to contact and conduct with the upper grounding terminal and / or the lower grounding terminal, so that the middle clip is grounded, effectively avoiding the generation of static electricity, thereby making the overall anti-static effect of the product better and meeting the needs of use.

[0048] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
