The second wall portion 612, the third wall portion 613 and the fourth wall portion 614 are further provided with a fixing tab 617 for assembling and fixing the shielding sheet 6 to the first insulating block 41. Preferably, the fixing tab 617 is provided with a plurality of barbs to improve the fixing effect with the first insulating block 41.

[0068] The plurality of grounding elastic arms 62 include first grounding elastic arms 621 arranged in the same row (e.g. the lower row) as the first elastic arms 421 and second grounding elastic arms 622 arranged in the same row (e.g. the upper row) as the second elastic arms 521. In the illustrated embodiment of the present application, the first grounding elastic arms 621 and the second grounding elastic arms 622 are arranged along the width direction of the insulating body 1, and the first grounding elastic arms 621 and the second grounding elastic arms 622 are arranged in different directions (see the arrow). Figure 13 The first grounding elastic arms 621 include first abutting portions 6211 extending into the docking slot 110, and the second grounding elastic arms 622 include second abutting portions 6221 extending into the docking slot 110.

[0069] The first insulating block 41 and the second insulating block 51 are provided with a buckling structure to clamp at least part of the main body 61 between the first insulating block 41 and the second insulating block 51. In the embodiment of the present application, the buckling structure includes but is not limited to the positioning column 413 and the positioning hole 513.

[0070] The terminal module 2 of the present application is assembled as follows: firstly, the first conductive terminal 42 is embedded in the first insulating block 41 to form the first terminal module 4; the second conductive terminal 52 is embedded in the second insulating block 51 to form the second terminal module 5; secondly, the shielding sheet 6 is installed on the first terminal module 4. At this time, the mounting hole 613 of the main body 61 is sleeved on the positioning column 413. At this time, the opening 610 is sleeved on the boss 416. Finally, the first terminal module 4 and the second terminal module 5 are assembled together to form a whole. At this time, the main body 61 is located between the first insulating block 41 and the second insulating block 51 in the thickness direction of the insulating body 1. The second tail 522 is accommodated in the accommodation groove 4142. The main body 61 is located in the periphery of the first tail 422 and the second tail 522, that is, the first tail 422 and the second tail 522 are located in the opening 610 and do not contact the main body 61. The first tail 422 and the second tail 522 are both exposed on the assembly surface 4141.

[0071] In the embodiment of the present application, neither the first conductive terminal 42 nor the second conductive terminal 52 includes a terminal with grounding function. The terminals with grounding function (i.e. the grounding elastic arm 62) are all arranged on the shielding sheet 6.

[0072] Please refer to Figures 8 to 14As shown, the first tail portion 422 and the second tail portion 522 are arranged in the width direction of the insulating body 1 and arranged in a row. In the first tail portion 422 and the second tail portion 522 in the row, any two adjacent tail portions are two first tail portions 422, or two second tail portions 522, or one first tail portion 422 and one second tail portion 522. In other words, only the first tail portion 422 of the first conductive terminal 42 and the second tail portion 522 of the second conductive terminal 52 occupy the width of the boss 414 (i.e. no other ground terminals occupy the width of the boss 414). In this way, under the development trend of more and more dense conductive terminals of the electrical connector, the conductive terminals can be arranged more easily, and the risk of short circuit between the conductive terminals is reduced. In addition, this design can also simplify the design and manufacture of the conductive terminals, and reduce the increase of material cost and manufacturing cost due to the continuous widening of the tail portions of the conductive terminals to both sides.

[0073] In an embodiment of the present application, the first tail portion 422 is used to be welded with the first signal cable 201, the second tail portion 522 is used to be welded with the second signal cable 202, and the second wall portion 612 of the main body portion 61 is used to be welded with the ground cable 203. The cable 200 includes the first signal cable 201, the second signal cable 202, and the ground cable 203.

[0074] The present application avoids the poor contact problem caused by connecting each ground terminal in series in the related art, and ensures the reliability of grounding. In addition, the shielding sheet 6 located between the first terminal module 4 and the second terminal module 5 greatly reduces the mutual interference of the upper and lower signals of the first conductive terminal 42 and the second conductive terminal 52 during data transmission, which is beneficial to high-frequency and high-fidelity transmission between signals. By arranging the first tail portion 422 and the second tail portion 522 in a single row, the connection with the cable can be completed by one welding, thereby reducing the welding difficulty, improving the welding reliability and performance stability, and avoiding the accumulation of multiple welding defects. In addition, based on the welding process used in this structure, coaxial and twisted pair wires can be simultaneously compatible, thereby expanding the application range.

[0075] In addition, the first fixed part 423 of the third terminal 42c includes a deflection part 42c1 across the first fixed part 423 of the first terminal 42a and the first fixed part 423 of the second terminal 42b, so that the arrangement order of the first tail part 422 of the third terminal 42c, the first tail part 422 of the first terminal 42a and the first tail part 422 of the second terminal 42b along the first direction A1 is different from the arrangement order of the first elastic arm 421 of the first terminal 42a, the first elastic arm 421 of the second terminal 42b and the first elastic arm 421 of the third terminal 42c along the first direction A1, thereby optimizing the arrangement of the first terminal 42a, the second terminal 42b and the third terminal 42c.
