Background
Electrical connectors (e.g., RJ45, USB, display-Port …, etc.) are widely used in various communication devices as a bridge for transmitting and connecting electrical signals. However, when the electric connector transmits high-frequency signals, electromagnetic waves and crosstalk interference can be generated, so that the stability of current and signal transmission is affected, and therefore, a convex hull or a convex block is mostly arranged on a middle partition plate between two rows of terminals of the electric connector to overlap with a grounding terminal and a shielding shell, so that the problem of uncovering before generation is avoided.

The first shielding plate 60 is made of a metal material such as copper, brass, nickel, silver, steel, tin or alloys thereof, but the present utility model is not limited thereto. The first shielding piece 60 is inserted into the base 11 and is located between the first terminal block 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 may be inserted in the bottom 114 of the base 11 in other embodiments. The first shielding plate 60 has a plurality of first end spring arms 61 and at least one first housing spring arm 62. Each first end sub-arm 61 extends obliquely from the first shielding plate 60 toward the first terminal row 30 and elastically overlaps each first ground terminal 31 to form an electrical connection, that is, each first end sub-arm 61 in the present embodiment extends obliquely downward to the first terminal row 30 and elastically overlaps each first ground terminal 31.

In the present embodiment, the second shielding plate 70 is inserted in the bottom 114 of the base 11, that is, the second shielding plate 70 is located below the second terminal row 40, but may be inserted in the top 113 of the base 11 in other embodiments. The second shielding plate 70 has a plurality of second end spring arms 71 and at least one second housing spring arm 72. Each second end sub-arm 71 extends obliquely from the second shielding plate 70 toward the second terminal row 40 and elastically overlaps each second ground terminal 41 to form an electrical connection, that is, each second end sub-arm 71 extends obliquely upward to the second terminal row 40 and elastically overlaps each second ground terminal 41.

For further illustration, referring to fig. 3 and 5, the first shielding plate 60 has a partition spring arm 63. The spacer spring arm 63 extends obliquely from one side of the first shielding plate 60 toward the middle spacer 50 and elastically overlaps the middle spacer 50 to form an electrical connection, i.e., the spacer spring arm 63 extends obliquely downward and elastically overlaps the middle spacer 50 in the present embodiment. Therefore, the electromagnetic shielding generated by the middle partition 50 can be conducted to the circuit board through the partition spring arm 63, the first shielding sheet 60, the first housing spring arm 62, the shielding housing 20 and the soldering leg 21 in sequence, so that the stability in high-frequency and high-speed transmission is effectively improved.
Referring to fig. 2, 3, 6 and 8, the top 113 of the base 11 has a first accommodating groove 116 and at least one first positioning groove 117. The first shielding plate 60 has at least one first positioning plate 64 corresponding to the number of the first positioning grooves 117, and the first positioning plate 64 is bent and extended from the first shielding plate 60. The first shielding plate 60 is accommodated in the first accommodating groove 116, and the first positioning plate 64 is inserted into the first positioning groove 117. In the present embodiment, the number of the first positioning slots 117 and the number of the first positioning tabs 64 are three, but the present utility model is not limited thereto, for example, the number of the first positioning slots 117 and the number of the first positioning tabs 64 may be two or more. Specifically, one of the first positioning slots 117 and the other two first positioning slots 117 are respectively located at two opposite sides of the first accommodating slot 116, and one of the first positioning plates 64 and the other two first positioning plates 64 are respectively located at two opposite sides of the first shielding plate 60. Thereby, the first positioning pieces 64 are respectively inserted and positioned in the first positioning grooves 117, so that the first shielding piece 60 is fixed in the first accommodating groove 116.
Referring to fig. 2, 4, 7 and 9, the bottom 114 of the base 11 has a second accommodating groove 118 and at least one second positioning groove 119. The second shielding plate 70 has at least one second positioning plate 73 corresponding to the number of the second positioning grooves 119, and the second positioning plate 73 is bent and extended from the second shielding plate 70. The second shielding plate 70 is accommodated in the second accommodating groove 118, and the second positioning plate 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 pieces 73 are one, but the utility model is not limited thereto, for example, the number of the second positioning grooves 119 and the number of the second positioning pieces 73 may be more than two. Specifically, the second accommodating groove 118 and the second positioning groove 119 are mutually communicated and adjacently arranged, and the base 11 extends to form a retaining wall 110 between the second accommodating groove 118 and the second positioning groove 119. The retaining wall 110 is stopped on one side of the second positioning plate 73, so as to cover the front side, the rear side, the left side and the right side of the second positioning plate 73 together with the second positioning groove 119. In the present embodiment, the number of the retaining walls 110 is two and are disposed opposite to each other, as shown in fig. 4 and 7, so as to provide the best stopping effect for the second positioning plate 73.
Referring back to fig. 4, each of the second end sub-arm 71 and the second positioning piece 73 are located on opposite sides of the second shielding piece 70. Accordingly, since the second positioning piece 73 is limited between the retaining wall 110 and the second positioning groove 119, the second shielding piece 70 generates an upward pivoting torque force, so that the second shielding piece 70 is tightly attached to the second accommodating groove 118, and meanwhile, each second end sub-arm 71 is tightly attached to the corresponding second grounding terminal 41, so as to effectively ensure the overlap between each second end sub-arm 71 and each second grounding terminal 41, as shown in fig. 8 and 9.
Referring to fig. 2 to 4, fig. 6 and fig. 7 again, in the present embodiment, the number of the first housing elastic arms 62 and the number of the second housing elastic arms 72 are two, but the present utility model is not limited thereto, and only one first housing elastic arm 62 and one second housing elastic arm 72 are required to achieve the conducting effect, and two first housing elastic arms 62 and two second housing elastic arms 72 are respectively adopted in the present embodiment to achieve the best conducting effect in a limited space, so the number of the first housing elastic arms 62 and the number of the second housing elastic arms 72 may be more than two. The first housing arms 62 and the first end arms 61 are arranged to be staggered with each other. The second housing arms 72 and the second end arms 71 are arranged to be staggered with each other.
In the electric connector structure of the present utility model, the first end bullet arm 61 and the first housing bullet arm 62 of the first shielding sheet 60 are respectively and elastically overlapped with the first grounding terminal 31 and the shielding housing 20 to form electric connection, and the second end bullet arm 71 and the second housing bullet arm 72 of the second shielding sheet 70 are respectively and elastically overlapped with the second grounding terminal 41 and the shielding housing 20 to form electric connection, so that under the condition that the distances between the first terminal row 30, the second terminal row 40 and the middle partition 50 and the shielding housing 20 are far, the interference of electromagnetic waves and remote crosstalk is still effectively improved, and the stability during high-frequency and high-speed transmission is improved; in addition, the first terminal row 30, the first shielding plate 60, the middle partition plate 50, the second terminal row 40 and the second shielding plate 70 can be assembled by plugging the rear end 112 of the base 11, so that the manufacturing process is not required to be performed by the embedding and injection process, and the assembly production can be easily performed and the production cost can be saved.
In view of the foregoing, the present utility model has industrial applicability, novelty and advancement. Of course, the present utility model is capable of other and further embodiments, and its several details are capable of modification and variation in light of the present teachings, as will be apparent to those of skill in the art and of modification and variation in light of the teachings herein, but are intended to cover such modifications and variations within the scope of this utility model as defined by the appended claims.
