Meanwhile, since the terminals of the docking connector 200 are in contact with the first contact portion 51 and the second contact portion 61, the electromagnetic field around the first contact portion 51 and the second contact portion 61 is denser and is subjected to more signal interference than the first connection portion 52 and the second connection portion 62, whereas the present embodiment relatively increases the distance between the first contact portion 51 and the second contact portion 61, and can reduce the signal interference between the first contact portion 51, the second contact portion 61 and the terminals of the docking connector 200.

Referring to fig. 5 and 6, the first shielding plate 7 and the second shielding plate 8 are separated from each other and are disposed with the plate surfaces facing each other, and a portion of the first shielding plate 7 and a portion of the second shielding plate 8 are located between the first contact portion 51 and the second contact portion 61. Therefore, the first shielding plate 7 and the second shielding plate 8 included in the insulating body 4 of the electrical connector 100 are located between the first terminal 5 and the second terminal 6, and crosstalk signals between the first terminal 5 and the second terminal 6 can be shielded twice by the first shielding plate 7 and the second shielding plate 8; meanwhile, compared with the first shielding sheet 7 and the second shielding sheet 8 which are in direct contact, when a current is induced in one of the shielding sheets by the electromagnetic field of the signal terminals S1 in the first row, the first shielding sheet 7 and the second shielding sheet 8 are separated from each other, and the air between the first shielding sheet 7 and the second shielding sheet 8 has weak signal conduction, so that the current can be prevented from being transmitted to the other shielding sheet to generate an interference signal affecting the signal terminals S2 in the second row, and the crosstalk interference between the signal terminals S1 in the first row and the signal terminals S2 in the second row can be reduced by the first shielding sheet 7 and the second shielding sheet 8 which are separated from each other; moreover, compared with the case of only one shielding plate, the first shielding plate 7 and the second shielding plate 8 which are separated from each other are arranged in the insulating body 4, so that the distance between the first terminal 5 and the corresponding shielding plate and the distance between the second terminal 6 and the corresponding shielding plate can be shortened, the gap between the signal terminal S1 in the first row and the gap between the signal terminal S2 in the second row and the corresponding shielding plate are smaller, external signals are not easy to enter the gaps to cause signal interference on the signal terminals, and meanwhile, the capacitive coupling between the signal terminals and the corresponding shielding plates can be increased, which is beneficial to reducing the impedance of the signal terminals, reducing the signal loss and facilitating the signal transmission of the electrical connector 100.

Referring to fig. 5 and 6, in the present embodiment, the first shielding plate 7 is provided with a first straight section 71, a second straight section 73 and a first inclined section 72, a first end and a second end of the first inclined section 72 are respectively connected to the first straight section 71 and the second straight section 73, the second shielding plate 8 is provided with a third straight section 81, a fourth straight section 83 and a second inclined section 82, a first end and a second end of the second inclined section 82 are respectively connected to the third straight section 81 and the fourth straight section 83, the first straight section 71 and the third straight section 81 are arranged in parallel in the tongue portion 41, and the second straight section 73 and the fourth straight section 83 are arranged in parallel in the base portion 42. The first and

second shielding plates

7, 8 are shaped to conform to the bent shape of the insulative housing 4, such that the first and

second shielding plates

7, 8 are disposed between the first and

second terminals

5, 6 and fixed to the insulative housing 4. The first shielding plate 7 and the second shielding plate 8 in this embodiment each have a plate body extending from a tongue portion 41 to the base portion 42, and the shielding area is large, so that crosstalk interference can be shielded to a greater extent for the signal terminals S1 in the first row and the signal terminals S2 in the second row, the shielding effect is more significant, and signal transmission of the electrical connector 100 is facilitated. Further, a first distance D1 exists between the first straight plate section 71 and the third straight plate section 81, a second distance D2 exists between the second straight plate section 73 and the fourth straight plate section 83, the first distance D1 is greater than the second distance D2, and a distance between a first end of the first inclined section 72 and a first end of the second inclined section 82 is not greater than a distance between a second end of the first inclined section 72 and a second end of the second inclined section 82, i.e., a third distance L3 shown in fig. 6 is not greater than a fourth distance L4. In the present embodiment, by setting the second distance D2 to be smaller than the first distance D1, the size of the base portion 42 along the second direction Z can be reduced, and the electrical connector 100 can be prevented from being too large in the second direction Z. Assuming that the first and second

inclined segments

72 and 82 are arranged in parallel, if the second distance D2 is smaller than the first distance D1, the second end of the first inclined segment 72 will be caused to be closer to the second end of the second inclined segment 82, when there is a production error in the inclination angle of the first inclined section 72 or the second inclined section 82, the first shielding plate 7 and the second shielding plate 8 are easily brought into contact and conducted, therefore, the third distance L3 in this embodiment is not greater than the fourth distance L4, the second end of the first inclined section 72 and the second end of the second inclined section 82 can be relatively pulled apart, the risk of the second end of the first inclined section 72 contacting the second end of the second inclined section 82 due to an error in the inclination angle is reduced, and this embodiment can effectively ensure that the first shielding plate 7 and the second shielding plate 8 are isolated from each other.

Referring to fig. 5 and 6, and fig. 9 to 11, the first shielding plate 7 has a plurality of first openings 74 and a plurality of first abutting portions 76 respectively extending from edges of the plurality of first openings 74, and the second shielding plate 8 has a plurality of second openings 84 and a plurality of second abutting portions 86 respectively extending from edges of the plurality of second openings 84. The first abutting portion 76 abuts against the first connecting portion 52 of the ground terminal G1 of the first row, the second abutting portion 86 abuts against the second connecting portion 62 of the ground terminal G2 of the second row, the first opening 74 and the second opening 84 are completely staggered, the first shielding plate 7 blocks the second opening 84 in a direction perpendicular to the second opening 84, and the second shielding plate 8 blocks the first opening 74 in a direction perpendicular to the first opening 74. In the present invention, the first abutting portion 76 electrically connects the ground terminal G1 of the first row and the first shield plate 7 to form an integral ground structure, and the second abutting portion 86 electrically connects the ground terminal G2 of the second row and the second shield plate 8 to form an integral ground structure, thereby improving the high-frequency performance of the electrical connector 100. Further, the first opening 74 and the second opening 84 are completely staggered, the first shielding plate 7 shields the second opening 84, and the second shielding plate 8 shields the first opening 74, so that signal interference caused by the first opening 74 and the second opening 84 forming a through notch together can be avoided, and crosstalk interference between the signal terminals S1 in the first row and the signal terminals S2 in the second row can be reduced. In this embodiment, each of the first abutting portions 76 abuts against one end of the second connecting segment 523 connected to the first bending segment 522 of the corresponding one of the ground terminals G1 in the first row, and each of the second abutting portions 86 abuts against one end of the fourth connecting segment 623 connected to the second bending segment 622 of the corresponding one of the ground terminals G2 in the second row. Since the positions where the ground terminals are abutted are overlapped by the thickness of the first abutting portion 76 or the second abutting portion 86, and the impedance changes, the positions where the ground terminals in the two rows are abutted in the embodiment are respectively near the first bending section 522 and the second bending section 622, and are both near the positions where the ground terminals are bent and extended, so that the impedance changes of the ground terminals in the two rows can be consistent; and the first abutment 76 can provide a certain supporting force for the first bending section 522.

Further, referring to fig. 12 and 13, the ground terminals G1 of the first row block the first openings 74 along a direction perpendicular to the first openings 74, respectively, and the ground terminals G2 of the second row block the second openings 84 along a direction perpendicular to the second openings 84, respectively. Since the signal terminals S1 of the first row and the signal terminals S2 of the second row emit interference signals outwards to form an external interference attack, in this embodiment, the positions of the signal terminals S1 of the first row corresponding to the second opening 84 can still be shielded and isolated twice by the first shielding plate 7 and the ground terminals G2 of the second row, so that the interference attack emitted outwards is reduced; similarly, the position of the signal terminal S2 in the second row corresponding to the first opening 74 can still be shielded and isolated twice by the second shielding plate 8 and the ground terminal G1 in the first row, so as to reduce the interference attack emitted to the outside.
