The at least two second resistive load terminals 41 are used to connect resistive loads to optimize signal crosstalk between the third terminal group 13 and the fourth terminal group 14.
[0050] Furthermore, the third signal terminal 131, the third ground terminal 132, the fourth signal terminal 141, the fourth ground terminal 142, and the second resistive load terminal 41 have essentially the same structure. Each terminal includes a second upright section 1201 extending vertically, a second contact section 1202 integrally connected to the upper end of the second upright section 1201, and a second mating section 1203 integrally connected to the lower end of the second upright section 1201.

[0051] Furthermore, the left cavity wall 1013 and the right cavity wall 1014 are recessed to form a second mounting groove 103 that opens rearward and communicates with the docking cavity 101 in the left-right direction.

Furthermore, the front surface of one of the second insulating blocks 1002 is in close contact with the rear surface of the insulating block 22 of the grounding structure 2.
[0052] Please refer to the reference. Figure 7 and Figure 8 As shown, the front surfaces of the second upright sections 1201 of the third grounding terminal 132 and the fourth grounding terminal 142 are exposed on the surface of the second insulating block 1002. The connector of this application also includes a shorting member 5, which is formed by bending a metal plate. The shorting member 5 shorts the front surfaces of the second upright sections 1201 of the third grounding terminal 132 and the fourth grounding terminal 142. When the second terminal module 200 and the grounding structure 2 are both assembled and fixed into the insulating body 10, the shorting member 5 is located between the second insulating block 1002 and the insulating block 22 of the grounding structure 2. The shorting member 5 can reduce mutual interference between the first terminal block and the second terminal block, improve the shielding effect, and thus improve the signal transmission rate. In a more preferred embodiment, at least two of the first resistive load terminals 31 and at least two of the second resistive load terminals 41 are arranged at intervals corresponding to each other.
[0053] The functional definitions of the terminals of the connector in this application are shown in Table 1 below:
[0054]
[0055] This embodiment reduces mutual interference between adjacent signal terminals by providing grounding terminals on both sides of each signal terminal, thereby enabling the transmission of radio frequency signals. Each terminal group can transmit one set of signals, and multiple terminal groups can be arranged as needed to achieve the transmission of multiple sets of signals. Furthermore, the grounding structure 2 and the shorting piece 5 can isolate adjacent terminal groups from each other, further improving the shielding effect and reducing electromagnetic interference. More importantly, the connector of this application adds a first resistive load terminal 31 and a second resistive load terminal 41, which can further improve the crosstalk problem by connecting resistive loads.
