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 portion 522 is received in the receiving groove 4142. The main body 61 is located around the first tail portion 422 and the second tail portion 522, that is, the first tail portion 422 and the second tail portion 522 are located in the opening 610 and do not contact the main body 61. The first tail portion 422 and the second tail portion 522 are both exposed on the assembly surface 4141.

In the embodiment of the present invention, the plurality of first conductive terminals 42 and the plurality of second conductive terminals 52 do not include terminals with a grounding function. The terminals with a grounding function (i.e., the grounding elastic arms 62) are all disposed on the shielding sheet 6.

Please refer to FIGS. 8 to 14 , the first tail portion 422 and the second tail portion 522 are interlaced and arranged in a row along the width direction of the insulating body 1. In the first tail portion 422 and the second tail portion 522 in this row, any two adjacent ones 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 grounding terminal occupies the width of the boss 414). With this arrangement, as the conductive terminals of electrical connectors are increasingly densely packed, the conductive terminals can be arranged more conveniently, reducing the risk of short circuits between the conductive terminals. In addition, this design can also simplify the design and manufacturing of the conductive terminals, reducing the increase in material costs and manufacturing costs caused by the continuous widening of the tail of the conductive terminal to both sides.

In one embodiment of the present invention, the first tail portion 422 is used to weld with the first signal cable 201, the second tail portion 522 is used to weld with the second signal cable 202, and the second wall portion 612 of the main body 61 is used to weld with the ground cable 203. The cable 200 includes the first signal cable 201, the second signal cable 202, and the ground cable 203.

The present invention avoids the problems such as poor contact caused by connecting the grounding terminals in series in the related art by providing an integrated shielding sheet 6, thereby ensuring grounding reliability. In addition, the shielding sheet 6 located between the aforementioned first terminal module 4 and the aforementioned second terminal module 5 greatly reduces the mutual interference of the signals between the upper and lower layers 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 422 and the second tail 522 in a single row, the connection with the cable can be completed by welding once, thereby reducing the difficulty of welding, improving the welding reliability and performance stability, and avoiding the accumulation of defects caused by multiple welding. In addition, based on the welding process adopted by this structure, it can be compatible with coaxial and twisted core wires at the same time, expanding the scope of application.

In addition, the first fixing portion 423 of the third terminal 42c includes a deflection portion 42c1 that crosses the first fixing portion 423 of the first terminal 42a and the first fixing portion 423 of the second terminal 42b, so that the arrangement sequence of the first tail portion 422 of the third terminal 42c, the first tail portion 422 of the first terminal 42a, and the first tail portion 422 of the second terminal 42b along the first direction A1 is different from the arrangement sequence 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.
