[0002] Electrical connectors (such as RJ45, USB, Display-Port, etc.) are widely used in various communication devices as a bridge for the transmission and connection of electronic signals. However, when transmitting high-frequency signals, electrical connectors will generate electromagnetic waves and crosstalk interference, thus affecting the stability of current and signal transmission. Therefore, most general electrical connectors will set convex bumps or bumps on the middle partition between the double-row terminals to overlap with the ground terminal and the shielding shell to avoid the above-mentioned problem.

[0003] However, when the distance between the conductive terminal and the middle partition and the shielding shell is far, the middle partition needs to be extended to overlap with the shielding shell, which is not only difficult to manufacture, but also easy to cause problems in the stability and strength of the overall structure.

[0060] The detailed description and technical contents of the present invention will be described as follows with reference to the drawings. However, the drawings are only for illustration purposes and are not intended to limit the present invention.

[0061] The present invention provides an electrical connector structure, please refer to Figures 1 to 5 As shown, it includes an insulating body 10 , a shielding shell 20 , a first terminal row 30 , a second terminal row 40 , a middle partition 50 , a first shielding sheet 60 and a second shielding sheet 70 .

[0062] In the present embodiment, the insulating body 10 is integrally formed by plastic injection molding, but the present invention is not limited thereto. For example, the insulating body 10 may also be made of other insulating materials. The insulating body 10 includes a base 11 and a tongue plate 12. The base 11 has a front end 111 and a rear end 112 opposite to each other, and a top 113 and a bottom 114 opposite to each other from top to bottom. The tongue plate 12 extends from the front end 111 of the base 11. The tongue plate 12 has a first end face 121 and a second end face 122 opposite to each other from top to bottom. In the present embodiment, the first end face 121 is located above the tongue plate 12, and the second end face 122 is located below the tongue plate 12, but in other embodiments, the opposite arrangement may also be used. The base 11 has a flat groove 115. The flat groove 115 is extended inward from the rear end 112 and is located in the tongue plate 12.

[0063] The shielding shell 20 is made of metal materials such as copper, brass, nickel, silver, steel, tin or alloys thereof, but the present invention is not limited to the above. The shielding shell 20 is sleeved on the outside of the insulating body 10. Specifically, the shielding shell 20 covers the upper side, lower side, left side and right side of the insulating body 10, thereby exposing the front and rear ends of the insulating body 10 for respectively providing a docking connector (not shown) for plugging and soldering the terminal pins to the circuit board (not shown). The shielding shell 20 has a plurality of solder pins 21 on the left and right sides of the bottom 114 that can be soldered to the circuit board.

[0064] The first terminal row 30 is inserted into the insulating body 10 from the rear end 112 of the base 11 and is disposed on the first end surface 121 of the tongue plate 12, but in other embodiments, it can also be disposed on the second end surface 122 of the tongue plate 12. The first terminal row 30 includes a plurality of first grounding terminals 31, a plurality of first power terminals, and a plurality of first signal terminals. Each of the first grounding terminals 31, each of the first power terminals, and each of the first signal terminals is made of a conductive material.

[0065] The second terminal row 40 is inserted into the insulating body 10 from the rear end 112 of the base 11 and is disposed on the second end surface 122 of the tongue plate 12, but in other embodiments, it can also be disposed on the first end surface 121 of the tongue plate 12. The second terminal row 40 includes a plurality of second grounding terminals 41, a plurality of second power terminals, and a plurality of second signal terminals. Each second grounding terminal 41, each second power terminal, and each second signal terminal are made of conductive material.

[0066] The middle partition 50 is made of metal materials such as copper, brass, nickel, silver, steel, tin or alloys thereof, but the present invention is not limited to the above. The middle partition 50 is accommodated inside the tongue plate 12 and is located between the first terminal row 30 and the second terminal row 40. Specifically, the middle partition 50 is inserted into the flat groove 115 from the rear end 112 of the base 11. In this way, electromagnetic shielding can be generated between the first terminal row 30 and the second terminal row 40, thereby avoiding signal interference between the first terminal row 30 and the second terminal row 40.

[0067] The first shielding sheet 60 is made of a metal material such as copper, brass, nickel, silver, steel, tin or an alloy thereof, but the present invention is not limited to the above. The first shielding sheet 60 is inserted in the base 11 and is located between the first terminal row 30 and the shielding shell 20. In the present embodiment, the first shielding sheet 60 is inserted in the top 113 of the base 11, that is, the first shielding sheet 60 is located above the first terminal row 30, but in other embodiments, it can also be inserted in the bottom 114 of the base 11. The first shielding sheet 60 has a plurality of first end elastic arms 61 and at least one first shell elastic arm 62. Each first end elastic arm 61 extends obliquely from the first shielding sheet 60 toward the first terminal row 30 and elastically overlaps each first grounding terminal 31 to form an electrical connection, that is, each first end elastic arm 61 in the present embodiment extends obliquely downward to the first terminal row 30 and elastically overlaps each first grounding terminal 31. The first shell elastic arm 62 extends obliquely from the first shielding sheet 60 toward the shielding shell 20 and elastically overlaps the shielding shell 20 to form an electrical connection. That is, the first shell elastic arm 62 in this embodiment extends obliquely upward and elastically overlaps the inner wall of the top 113 of the shielding shell 20.

[0068] The second shielding sheet 70 is made of a metal material such as copper, brass, nickel, silver, steel, tin or an alloy thereof, but the present invention is not limited to the above. The second shielding sheet 70 is inserted in the base 11 and is located between the second terminal row 40 and the shielding shell 20. In the present embodiment, the second shielding sheet 70 is inserted in the bottom 114 of the base 11, that is, the second shielding sheet 70 is located below the second terminal row 40, but in other embodiments, it can also be inserted in the top 113 of the base 11. The second shielding sheet 70 has a plurality of second terminal elastic arms 71 and at least one second shell elastic arm 72. Each second terminal elastic arm 71 extends obliquely from the second shielding sheet 70 toward the second terminal row 40 and elastically overlaps each second grounding terminal 41 to form an electrical connection, that is, each second terminal elastic arm 71 in the present embodiment extends obliquely upward to the second terminal row 40 and elastically overlaps each second grounding terminal 41. The second shell elastic arm 72 extends obliquely from the second shielding sheet 70 toward the shielding shell 20 and elastically overlaps the shielding shell 20 to form an electrical connection. That is, the second shell elastic arm 72 in this embodiment extends obliquely downward and elastically overlaps the inner wall of the bottom 114 of the shielding shell 20.

[0069] As can be seen from the above, each first grounding terminal 31 of the first terminal row 30 is overlapped through each first terminal elastic arm 61 of the first shielding sheet 60, and is overlapped with the shielding shell 20 through the first shell elastic arm 62 of the first shielding sheet 60; and each second grounding terminal 41 of the second terminal row 40 is overlapped through each second terminal elastic arm 71 of the second shielding sheet 70, and is overlapped with the shielding shell 20 through the second shell elastic arm 72 of the second shielding sheet 70. In this way, the electromagnetic waves and crosstalk interference generated by the first terminal row 30 and the second terminal row 40 can be conducted to the solder pins 21 of the shielding shell 20 and the circuit board, thereby effectively improving the interference of electromagnetic waves and long-range crosstalk during transmission, and at the same time can improve the stability during high-frequency and high-speed transmission.

[0070] For further instructions, see Figure 3 and Figure 5 As shown, the first shielding sheet 60 has a partition elastic arm 63. The partition elastic arm 63 extends obliquely from one side of the first shielding sheet 60 toward the middle partition 50 and elastically overlaps the middle partition 50 to form an electrical connection, that is, the partition elastic arm 63 in this embodiment extends obliquely downward and elastically overlaps the middle partition 50. In this way, the electromagnetic shielding generated by the middle partition 50 can also be transmitted to the circuit board through the partition elastic arm 63, the first shielding sheet 60, the first shell elastic arm 62, the shielding shell 20 and the solder pin 21 in sequence, thereby effectively improving the stability during high-frequency and high-speed transmission.

[0071] See also Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, the top 113 of the base 11 has a first receiving groove 116 and at least one first positioning groove 117. The first shielding sheet 60 has at least one first positioning piece 64 corresponding to the number of the first positioning grooves 117, and the first positioning piece 64 is bent and extended from the first shielding sheet 60. The first shielding sheet 60 is accommodated in the first receiving groove 116, and the first positioning piece 64 is inserted and set in the first positioning groove 117. In this embodiment, the number of the first positioning grooves 117 and the number of the first positioning pieces 64 are both three, but the present invention is not limited thereto, for example, the number of the first positioning grooves 117 and the number of the first positioning pieces 64 can also be two or more than four. Specifically, one of the first positioning grooves 117 and the other two first positioning grooves 117 are respectively located on opposite sides of the first receiving groove 116, and one of the first positioning pieces 64 and the other two first positioning pieces 64 are respectively located on opposite sides of the first shielding sheet 60. Thus, each first positioning piece 64 is inserted and positioned in each first positioning groove 117 , so that the first shielding piece 60 is fixed in the first receiving groove 116 .

[0072] Please read next Figure 2, Figure 4 , Figure 7 and Fig. 9 As shown, the bottom 114 of the base 11 has a second receiving groove 118 and at least one second positioning groove 119. The second shielding sheet 70 has at least one second positioning piece 73 corresponding to the number of the second positioning grooves 119, and the second positioning piece 73 is bent and extended from the second shielding sheet 70. The second shielding sheet 70 is accommodated in the second receiving groove 118, and the second positioning piece 73 is inserted and set in the second positioning groove 119. In this embodiment, the number of the second positioning grooves 119 and the number of the second positioning pieces 73 are both one, but the present invention is not limited to this. For example, the number of the second positioning grooves 119 and the number of the second positioning pieces 73 can also be more than two. Specifically, the second receiving groove 118 and the second positioning groove 119 are interconnected and arranged adjacent to each other, and the base 11 extends a retaining wall 110 between the second receiving groove 118 and the second positioning groove 119. The retaining wall 110 is stopped at one side of the second positioning piece 73, so as to cover the front side, rear side, left side and right side of the second positioning piece 73 together with the second positioning groove 119. In this embodiment, the number of retaining walls 110 is two and they are arranged opposite to each other. Figure 4 and Figure 7 As shown, the second positioning piece 73 is optimally stopped.

[0073] See also Figure 4 As shown, each second end bullet arm 71 and the second positioning piece 73 are respectively located on opposite sides of the second shielding piece 70. Accordingly, since the second positioning piece 73 is restricted between the retaining wall 110 and the second positioning groove 119, the second shielding piece 70 will generate a torque force to pivot upward, so that the second shielding piece 70 is closely attached to the second receiving groove 118, and at the same time, each second end bullet arm 71 is closely attached to the corresponding second grounding terminal 41, so as to effectively ensure the overlap between each second end bullet arm 71 and each second grounding terminal 41, as shown in FIG. Figure 8 and Fig. 9 shown.

[0074] See also Figures 2 to 4 and Figure 6 , Figure 7 As shown, in this embodiment, the number of the first shell elastic arms 62 and the number of the second shell elastic arms 72 are both two, but the present invention is not limited thereto. Only one first shell elastic arm 62 and one second shell elastic arm 72 are needed to achieve the conduction effect. Two are used in this embodiment to achieve the best conduction effect in a limited space. Therefore, the number of the first shell elastic arms 62 and the number of the second shell elastic arms 72 can also be more than two. Each first shell elastic arm 62 and each first end elastic arm 61 are staggered. Each second shell elastic arm 72 and each second end elastic arm 71 are staggered.

[0075] The electrical connector structure of the present invention forms an electrical connection by elastically overlapping each first end elastic arm 61 and the first shell elastic arm 62 of the first shielding sheet 60 with each first grounding terminal 31 and the shielding shell 20, and elastically overlapping each second end elastic arm 71 and the second shell elastic arm 72 of the second shielding sheet 70 with each second grounding terminal 41 and the shielding shell 20, so that when the first terminal row 30, the second terminal row 40 and the middle partition plate 50 are far away from the shielding shell 20, the interference of electromagnetic waves and long-range crosstalk is still effectively improved to enhance the stability during high-frequency and high-speed transmission; in addition, the first terminal row 30, the first shielding sheet 60, the middle partition plate 50, the second terminal row 40 and the second shielding sheet 70 can all be plugged and assembled by the rear end 112 of the base 11, so there is no need to produce them through an embedded injection molding process, so that they can be easily assembled and produced and save production costs.

[0076] In summary, the present invention has industrial applicability, novelty and progress. Of course, the present invention may have other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may evolve various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations shall all fall within the scope of protection of the patent applied for by the present invention.
