[0002] Type-C is a USB interface standard that is smaller than Type-A and Type-B. It can be used in both PCs (host devices) and external devices (slave devices, such as mobile phones). USB Type-C has four pairs of TX / RX breakout lines, two pairs of USB D+ / D-, one SBU pair, two CC lines, four VBUS lines, and four ground lines.

[0003] The main structure of the current Type-C connector includes an insulating body, a shielding shell, an upper row of terminals, a lower row of terminals and a middle clip; the shielding shell is covered on the outside of the insulating body, and the shielding shell is formed by stamping and riveting; the upper row of terminals, the lower row of terminals and the middle clip are all arranged on the insulating body, the upper row of terminals has an upper ground terminal and an upper power terminal, the lower row of terminals has a lower ground terminal and a lower power terminal, and the middle clip is located between the upper row of terminals and the lower row of terminals.

[0004] In existing technology, the shielding shell's riveted joints are typically riveted left and right, up and down, which can easily cause the upper and lower parts to separate, resulting in an unstable overall structure. Furthermore, the Type-C connector's center clip is typically a single piece with a large area covering all terminals, making it prone to short-circuiting with the power terminals. This results in poor stability and reliability. Therefore, improvements to the existing Type-C connector are necessary. Utility Model Content

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A stable sunken-plate Type-C connector comprises an insulating body, a shielding shell, an upper row of terminals, a lower row of terminals and a middle clip; the shielding shell is wrapped around the insulating body and formed by stamping and riveting; the upper row of terminals, the lower row of terminals and the middle clip are all arranged on the insulating body, the upper row of terminals has an upper grounding terminal and an upper power terminal, the lower row of terminals has a lower grounding terminal and a lower power terminal, and the middle clip is located between the upper row of terminals and the lower row of terminals; the riveted joints of the shielding shell are fixedly connected by spot welding to form multiple welding points, and the multiple welding points are spaced front to back and staggered left to right; the middle clips are two separately arranged on the left and right, each middle clip is respectively located between the corresponding upper grounding terminal and the corresponding lower grounding terminal, and each middle clip is separately arranged on the left and right with the corresponding upper power terminal and the corresponding lower power terminal.

[0008] As a preferred solution, the left and right sides of the shielding shell are punched and bent to extend front and rear fixing feet, which are arranged at intervals in front and back, and are bent outward at the upper and lower middle positions of the side of the shielding shell.

[0009] As a preferred solution, the front fixing legs and the rear fixing legs are both in an inverted L-shape, and the width of the front fixing legs is greater than that of the rear fixing legs.

[0010] As a preferred solution, a slot is provided in the middle of the bent connection of the front fixing foot. The slot is in an inverted L-shape and passes through the inner and outer sides of the front fixing foot. The slot can be used to accommodate solder paste to better fix the front fixing foot on the circuit board.

[0011] As a preferred solution, the insulating body includes an outer insulating part, an upper insulating part and a lower insulating part. The upper insulating part and the lower insulating part are assembled and fixed up and down and inlaid in the outer insulating part. The upper row of terminals are inlaid and fixed together with the upper insulating part, and the lower row of terminals and the middle clip are inlaid and fixed together with the lower insulating part.

At the same time, the middle clips are designed to be separated into two parts on the left and right, and each middle clip is staggered and separated from the corresponding power terminal to prevent short circuits, thereby effectively improving the stability and reliability of the product.

[0037] 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.

[0038] The insulating body 10 includes an outer insulating part 11, an upper insulating part 12 and a lower insulating part 13; the outer insulating part 11 includes a base 111 and a tongue plate 112 extending forward from the base 111, and the top of the base 111 is recessed with a rivet hole 101, and there are two rivet holes 101 spaced apart on the left and right; the upper insulating part 12 and the lower insulating part 13 are assembled and fixed up and down and fixed in the outer insulating part 11 by inlay molding; and the upper surface of the lower insulating part 13 is recessed with two positioning holes 102 arranged on the left and right, and the lower surface of the upper insulating part 12 extends with two positioning columns 103 arranged on the left and right, and the positioning columns 103 are inserted into the positioning holes 102 for positioning, with a simple structure and easy assembly.

[0039] The shielding shell 20 is wrapped around the insulating body 10 and is formed by stamping and riveting. The riveted joints of the shielding shell 20 are fixedly connected by spot welding to form a plurality of weld points 21. The plurality of weld points 21 are spaced apart front to back and staggered left to right, making the shielding shell 20 structurally stable. In this embodiment, the left and right sides of the shielding shell 20 are punched and bent to extend front and rear fixing legs 22 and 23. The front and rear fixing legs 22 and 23 are spaced apart front to back, and both are bent outward from the upper and lower middle positions of the side of the shielding shell 20 to achieve sunken plate installation on the circuit board 60. Furthermore, the front and rear fixing legs 22 and 23 are both in an inverted L-shape, with the width of the front fixing leg 22 being greater than the width of the rear fixing leg 23. This provides a simple structure, good strength, and easy installation. Furthermore, a slot 201 is defined in the middle of the bent connection of the front fixing leg 22. The slot 201 is in an inverted L-shape and extends through the inner and outer sides of the front fixing leg 22. The slot 201 can be used to accommodate solder paste to better secure the front fixing leg 22 to the circuit board 60. Furthermore, a rivet tab 24 extends downward from the top edge of the rear side of the shielding shell 20. Two rivet tabs 24 are provided on the left and right sides, and are riveted to the two rivet holes 101, respectively.

[0040] The upper row of terminals 30, the lower row of terminals 40, and the middle clip 50 are all disposed on the insulating body 10. The upper row of terminals 30 includes an upper grounding terminal 31 and an upper power terminal 32, while the lower row of terminals 40 includes a lower grounding terminal 41 and a lower power terminal 42. In this embodiment, the upper row of terminals 30 and the lower row of terminals 40 each have 8 pins, thus forming a 16-pin structure that meets the requirements of use. Furthermore, the upper grounding terminal 31, the upper power terminal 32, the lower grounding terminal 41, and the lower power terminal 42 are all arranged in two symmetrical positions. Furthermore, the soldering portions 301 of the upper row of terminals 30 and the soldering portions 401 of the lower row of terminals 40 are arranged in a row and extend horizontally backward outside the base 111 to facilitate SMT soldering and fixing to the circuit board 60. Furthermore, the upper row of terminals 30 are fixed to the upper insulating member 12 by insert molding, while the lower row of terminals 40 are fixed to the lower insulating member 13 by insert molding, resulting in a simple structure and easy assembly.

[0041] The middle clip 50 is located between the upper row of terminals 30 and the lower row of terminals 40. Two middle clips 50 are disposed separately on the left and right sides, with each middle clip 50 located between a corresponding upper grounding terminal 31 and a corresponding lower grounding terminal 41. Each middle clip 50 is staggered and separated from a corresponding upper power terminal 32 and a corresponding lower power terminal 42. In this embodiment, the middle clip 50 is fixed to the lower insulating member 13 by an inlay molding, making assembly easy. Furthermore, the upper and lower surfaces of the middle clip 50 are formed with a front through-hole 51 and a rear through-hole 52. The front through-hole 51 and the rear through-hole 52 are arranged front to back and are both embedded in the insulating body 10, so that the middle clip 50 and the insulating body 10 are firmly and reliably connected.

[0042] The assembly process of this embodiment is described in detail as follows:

[0043] First, the upper row of terminals 30, the lower row of terminals 40 and the middle clip 50 are stamped out, and the shielding shell 20 is prepared. Next, the upper row of terminals 30 are placed in the first injection mold, and the lower row of terminals 40 and the middle clip 50 are placed in the second injection mold to injection-mold the upper insulating part 12 and the lower insulating part 13 respectively. Then, the upper insulating part 12 and the lower insulating part 13 are combined and fixed together and placed in the third injection mold to injection-mold the outer insulating part 11. Finally, the shielding shell 20 covers the insulating body 10.

[0044] The design focus of the utility model is that multiple welding points are formed by spot welding the riveted joints of the shielding shell to effectively avoid the phenomenon of upper and lower misalignment and separation at the riveted joints, thereby making the overall structure of the product more stable. At the same time, the middle clip is designed to be separated into two parts on the left and right, and each middle clip is staggered and separated from the corresponding power terminal to prevent short circuits, thereby effectively improving the stability and reliability of the product.

[0045] 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.
