Description

TECHNICAL FIELD

[0001] The present application relates to an electrical connector structure, and more particularly to an electrical connector structure which is easy to assemble and manufacture and is capable of stable high-frequency and high-speed transmission. BACKGROUND

[0002] Electrical connectors (such as RJ45, USB, Display-Port, etc.) are widely used in various communication devices as a bridge for electronic signal transmission and connection. However, when electrical connectors transmit high-frequency signals, electromagnetic waves and crosstalk interference are generated, which affects the stability of current and signal transmission. Therefore, most general electrical connectors are provided with protrusions or bumps on the partition plate between the double-row terminals to be lapped with the ground terminals and the shielding shell, thereby avoiding the above problems.

[0003] However, when the distance between the conductive terminals, the partition plate and the shielding shell is far, the partition plate needs to be elongated to be lapped with the shielding shell. This not only makes it difficult to produce and manufacture, but also easily causes problems in the stability and strength of the overall structure. In addition, most general partition plates are embedded in the tongue plate by using the embedded injection molding process. Therefore, once the product design is changed or the size is adjusted, the mold needs to be re-opened. This not only makes the production process complicated, but also increases the production cost.

[0004] Therefore, the present inventors have made great efforts to solve the above problems by means of careful research and the application of theories, which is the improvement goal of the present application. SUMMARY

[0005] The main purpose of the present application is to improve the electromagnetic wave and long-distance crosstalk interference, to improve the stability of high-frequency and high-speed transmission, and to make the electrical connector easy to assemble and manufacture and save production cost.

[0006] To achieve the above object, the present application provides an electric connector structure, which comprises an insulating body, a shielding shell, a first terminal array, a second terminal array, a partition plate, a first shielding sheet and a second shielding sheet. The insulating body comprises a base and a tongue plate. The base has a front end and a rear end. The tongue plate extends from the front end. The tongue plate has a first end face and a second end face. The shielding shell covers the insulating body. The first terminal array is inserted into the insulating body from the rear end and arranged on the first end face. The first terminal array comprises a plurality of first grounding terminals. The second terminal array is inserted into the insulating body from the rear end and arranged on the second end face. The second terminal array comprises a plurality of second grounding terminals. The partition plate is accommodated in the tongue plate and located between the first terminal array and the second terminal array. The first shielding sheet is inserted into the base and located between the first terminal array and the shielding shell. The first shielding sheet has a plurality of first terminal spring arms and at least one first shell spring arm. Each first terminal spring arm extends from the first shielding sheet to the first terminal array and is lapped on each first grounding terminal. The first shell spring arm extends from the first shielding sheet to the shielding shell and is lapped on the shielding shell. The second shielding sheet is inserted into the base and located between the second terminal array and the shielding shell. The second shielding sheet has a plurality of second terminal spring arms and at least one second shell spring arm. Each second terminal spring arm extends from the second shielding sheet to the second terminal array and is lapped on each second grounding terminal. The second shell spring arm extends from the second shielding sheet to the shielding shell and is lapped on the shielding shell.

[0007] In an embodiment of the present application, the first shielding sheet has a partition plate spring arm. The partition plate spring arm extends from the first shielding sheet to the partition plate and is lapped on the partition plate.

[0008] In an embodiment of the present application, the base has a first accommodating groove and at least one first positioning groove. The first shielding sheet has at least one first positioning sheet. The first shielding sheet is accommodated in the first accommodating groove. The first positioning sheet is inserted into the first positioning groove.

[0009] In an embodiment of the present application, the number of the first positioning grooves and the number of the first positioning sheets are both three. One first positioning groove and the other two first positioning grooves are located on opposite sides of the first accommodating groove. One first positioning sheet and the other two first positioning sheets are located on opposite sides of the first shielding sheet. Each first positioning sheet is inserted into each first positioning groove.

[0010] In an embodiment of the present application, the base has a second accommodating groove and a second positioning groove. The second shielding sheet has a second positioning sheet. The second shielding sheet is accommodated in the second accommodating groove. The second positioning sheet is inserted into the second positioning groove.

[0011] In an embodiment of the present application, the second accommodating groove and the second positioning groove are in communication with each other and arranged adjacently. The base extends a barrier wall between the second accommodating groove and the second positioning groove. The barrier wall stops a side surface of the second positioning sheet.

[0012] In an embodiment of the present application, each second terminal spring arm and second positioning sheet are located on opposite sides of the second shielding sheet.

[0013] In an embodiment of the present application, the base has a flat groove extending inwardly from the rear end and located in the tongue plate, and the partition plate is inserted in the flat groove.

[0014] In an embodiment of the present application, the number of first housing spring arms is several, and each first housing spring arm is staggered with each first terminal spring arm.

[0015] In an embodiment of the present application, the number of second housing spring arms is several, and each second housing spring arm is staggered with each second terminal spring arm.

[0016] The electric connector structure of the present application effectively improves the interference of electromagnetic waves and far-end crosstalk, thereby improving the stability during high-frequency and high-speed transmission, by respectively lapping each first terminal spring arm and first housing spring arm of the first shielding sheet on each first grounding terminal and shielding housing, and respectively lapping each second terminal spring arm and second housing spring arm of the second shielding sheet on each second grounding terminal and shielding housing. In addition, the first terminal row, the first shielding sheet, the second terminal row, and the second shielding sheet can be assembled by inserting the rear end of the base, so that they do not need to be produced by embedding the outgoing process, thereby being easy to assemble and produce and saving production cost.

[0061] The present application provides an electrical connector structure, please refer to Figures 1 to 5 shown, which includes an insulating body 10, a shielding shell 20, a first terminal row 30, a second terminal row 40, a partition plate 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 application is not limited thereto. For example, the insulating body 10 can 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. The tongue plate 12 extends from the front end 111 of the base 11.

The base 11 has a flat groove 115. The flat groove 115 extends inwardly 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 application is not limited thereto. The shielding shell 20 is sleeved on the outside of the insulating body 10. Specifically, the shielding shell 20 covers the upper side, the lower side, the left side and the right side of the insulating body 10, so as to expose the front end and the rear end of the insulating body 10 for plugging of a mating connector (not shown) and soldering of terminal pins to a circuit board (not shown), respectively. The shielding shell 20 has a plurality of solder pins 21 capable of being soldered to the circuit board on the left and right sides of the bottom 114.

[0064] The first terminal row 30 is inserted into the insulating body 10 from the rear end 112 of the base 11 and arranged on the first end face 121 of the tongue plate 12, but in other embodiments, it can be arranged on the second end face 122 of the tongue plate 12.

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

[0066] The middle partition 50 is made of metal material such as copper, brass, nickel, silver, steel, tin or alloy thereof, but the present application is not limited thereto. The middle partition 50 is accommodated inside the tongue 12 and located between the first terminal row 30 and the second terminal row 40. Specifically, the middle partition 50 is inserted in the flat groove 115 from the rear end 112 of the base 11. By this way, electromagnetic shielding between the first terminal row 30 and the second terminal row 40 can be generated, so as to avoid signal interference between the first terminal row 30 and the second terminal row 40.

[0067] The first shielding sheet 60 is made of metal material such as copper, brass, nickel, silver, steel, tin or alloy thereof, but the present application is not limited thereto. The first shielding sheet 60 is inserted in the base 11 and 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 portion 113 of the base 11, i.e. the first shielding sheet 60 is located above the first terminal row 30, but in other embodiments, it can be inserted in the bottom portion 114 of the base 11. The first shielding sheet 60 has a plurality of first terminal spring arms 61 and at least one first shell spring arm 62. Each first terminal spring arm 61 is inclinedly extended from the first shielding sheet 60 towards the first terminal row 30 and elastically lapped on each first ground terminal 31 to form electrical connection, i.e. each first terminal spring arm 61 in the present embodiment is inclinedly extended downwards to the first terminal row 30 and elastically lapped on each first ground terminal 31. The first shell spring arm 62 is inclinedly extended from the first shielding sheet 60 towards the shielding shell 20 and elastically lapped on the shielding shell 20 to form electrical connection, i.e. the first shell spring arm 62 in the present embodiment is inclinedly extended upwards and elastically lapped on the inner wall of the top portion 113 of the shielding shell 20.

[0068] The second shielding sheet 70 is made of metal material such as copper, brass, nickel, silver, steel, tin or alloy thereof, but the present application is not limited thereto. The second shielding sheet 70 is inserted in the base 11 and 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 portion 114 of the base 11, i.e. the second shielding sheet 70 is located below the second terminal row 40, but in other embodiments, it can be inserted in the top portion 113 of the base 11. The second shielding sheet 70 has a plurality of second terminal spring arms 71 and at least one second shell spring arm 72. Each second terminal spring arm 71 is inclinedly extended from the second shielding sheet 70 towards the second terminal row 40 and elastically lapped on each second ground terminal 41 to form electrical connection, i.e. each second terminal spring arm 71 in the present embodiment is inclinedly extended upwards to the second terminal row 40 and elastically lapped on each second ground terminal 41. The second shell spring arm 72 is inclinedly extended from the second shielding sheet 70 towards the shielding shell 20 and elastically lapped on the shielding shell 20 to form electrical connection, i.e. the second shell spring arm 72 in the present embodiment is inclinedly extended downwards and elastically lapped on the inner wall of the bottom portion 114 of the shielding shell 20.

[0069] As described above, each first grounding terminal 31 of the first terminal block 30 is connected via each first end spring arm 61 of the first shielding plate 60, and is connected to the shielding shell 20 via the first outer shell spring arm 62 of the first shielding plate 60; while each second grounding terminal 41 of the second terminal block 40 is connected via each second end spring arm 71 of the second shielding plate 70, and is connected to the shielding shell 20 via the second outer shell spring arm 72 of the second shielding plate 70. In this way, the electromagnetic waves and crosstalk interference generated by the first terminal block 30 and the second terminal block 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 remote crosstalk during transmission, and simultaneously improving the stability during high-frequency and high-speed transmission.

[0070] For further explanation, please refer to Figure 3 and Figure 5 As shown, the first shielding sheet 60 has a partition spring arm 63. The partition spring 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, in this embodiment, the partition spring arm 63 extends downward and elastically overlaps the middle partition 50. In this way, the electromagnetic shielding generated by the middle partition 50 can also be conducted to the circuit board in sequence through the partition spring arm 63, the first shielding sheet 60, the first outer shell spring arm 62, the shielding outer shell 20, and the solder pad 21, thereby effectively improving the stability during high-frequency and high-speed transmission.

[0071] Please see 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 plate 60 has at least one first positioning piece 64 corresponding to the number of first positioning grooves 117, and the first positioning piece 64 extends out from the first shielding plate 60 by bending. The first shielding plate 60 is received in the first receiving groove 116, and the first positioning piece 64 is inserted and positioned in the first positioning groove 117. In this embodiment, the number of first positioning grooves 117 and the number of first positioning pieces 64 are both three, but the present invention is not limited thereto. For example, the number of first positioning grooves 117 and the number of first positioning pieces 64 can also be two or more. Specifically, one first positioning groove 117 and the other two first positioning grooves 117 are respectively located on opposite sides of the first receiving groove 116, and one first positioning piece 64 and the other two first positioning pieces 64 are respectively located on opposite sides of the first shielding plate 60. In this way, each first positioning piece 64 is respectively inserted into each first positioning groove 117, thereby fixing the first shielding piece 60 in the first receiving groove 116.

[0072] Please continue reading. Figure 2、 Figure 4 、 Figure 7 and Figure 9 As shown in Figure 4 and Figure 7 , the bottom 114 of the base 11 has a second accommodating groove 118 and at least one second positioning groove 119. The second shielding sheet 70 has at least one second positioning sheet 73 corresponding to the number of the second positioning grooves 119, and the second positioning sheet 73 is bent and extended from the second shielding sheet 70. The second shielding sheet 70 is accommodated in the second accommodating groove 118, and the second positioning sheet 73 is inserted and positioned in the second positioning groove 119. In the embodiment, the number of the second positioning grooves 119 and the number of the second positioning sheets 73 are both one, but the present application is not limited thereto, for example, the number of the second positioning grooves 119 and the number of the second positioning sheets 73 can also be more than two. Specifically, the second accommodating groove 118 and the second positioning groove 119 are arranged adjacent to each other and the base 11 extends a barrier wall 110 between the second accommodating groove 118 and the second positioning groove 119. The barrier wall 110 is stopped on one side of the second positioning sheet 73, thereby wrapping the front side, the back side, the left side and the right side of the second positioning sheet 73 together with the second positioning groove 119. In the embodiment, the number of the barrier walls 110 is two and they are arranged opposite to each other, as shown in Figure 4 and Figure 7 , so as to achieve the best stopping effect on the second positioning sheet 73.

[0073] Referring back to Figure 4 , each second terminal spring arm 71 and the second positioning sheet 73 are located on opposite sides of the second shielding sheet 70. Accordingly, since the second positioning sheet 73 is limited between the barrier wall 110 and the second positioning groove 119, a torsion force for upward pivoting of the second shielding sheet 70 is generated, so that the second shielding sheet 70 is tightly attached in the second accommodating groove 118, and each second terminal spring arm 71 is tightly attached to the corresponding second ground terminal 41, thereby effectively ensuring the overlap between each second terminal spring arm 71 and each second ground terminal 41, as shown in Figure 8 and Figure 9 .

[0074] Referring back to Figures 2 to 4 and Figure 6 , Figure 7 , in the embodiment, the number of the first housing spring arms 62 and the number of the second housing spring arms 72 are both two, but the present application is not limited thereto, and only one of the first housing spring arms 62 and the second housing spring arms 72 is needed to achieve the conduction effect, and two are used in the embodiment to achieve the best conduction effect in limited space, so the number of the first housing spring arms 62 and the number of the second housing spring arms 72 can also be more than two. Each first housing spring arm 62 and each first terminal spring arm 61 are arranged staggered with each other. Each second housing spring arm 72 and each second terminal spring arm 71 are arranged staggered with each other.

[0075] The electric connector structure of the present application forms electric connection by respectively elastically lapping each first terminal spring arm 61 of the first shielding sheet 60 and each first housing spring arm 62 on each first ground terminal 31 and the shielding housing 20, and forms electric connection by respectively elastically lapping each second terminal spring arm 71 of the second shielding sheet 70 and each second housing spring arm 72 on each second ground terminal 41 and the shielding housing 20, so that the electromagnetic wave and the remote crosstalk interference is effectively improved in the case that the distance between the first terminal row 30, the second terminal row 40, the partition plate 50 and the shielding housing 20 is far, and the stability during high frequency and high speed transmission is improved. In addition, the first terminal row 30, the first shielding sheet 60, the partition plate 50, the second terminal row 40 and the second shielding sheet 70 can be inserted and assembled from the rear end 112 of the base 11, so that the production and manufacturing is not needed by embedding and injection process, and the production and assembly is easy and the production cost is saved.

[0076] In summary, the present application has industrial applicability, novelty and progress. Of course, the present application can have other various embodiments, and those skilled in the art can evolve various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application. However, these corresponding changes and modifications should belong to the protection scope of the present application.
