When the wire-to-board connector 100 is assembled, the mounting holes 13 are aligned with the mounting holes 205 to allow the fasteners 300 to pass through. The positioning posts 14 are inserted into the positioning holes 206 to position the wire-to-board connector 100 on the circuit board 200. In the embodiment illustrated in the present invention, the first terminal module 21 is mounted from the first surface 11 into the first receiving opening 15, and the second terminal module 22 is mounted from the first surface 11 into the second receiving opening 16. The partition wall 17 is provided with a plurality of cable positioning grooves 171 for positioning the plurality of first cables 41.

[0055] Please combine Figure 7 As shown, the first terminal module 21 includes a first insulating block 211 and a plurality of first conductive terminals 212 fixed to the first insulating block 211. In the embodiment illustrated in the present invention, the plurality of first conductive terminals 212 are embedded in the first insulating block 211. Of course, those skilled in the art will understand that the plurality of first conductive terminals 212 can also be fixed to the first insulating block 211 by other means (e.g., assembly).

[0056] The plurality of first conductive terminals 212 are arranged at intervals along a first direction A1-A1 (e.g., left-right direction). Each first conductive terminal 212 includes a first elastic mating portion 2121, and at least a portion of the first conductive terminals 212 includes a first cable connection portion 2122. Please refer to... Figure 9 As shown by the dotted lines in the upper middle part, in the embodiment illustrated in the present invention, each first conductive terminal 212 is axially symmetrical. For example, the center line of the first elastic mating portion 2121 is aligned with the center line of the first cable connection portion 2122. The first elastic mating portion 2121 extends cantileveredly beyond the first insulating block 211. The first elastic mating portion 2121 extends downward beyond the first surface 11 to abut against the plurality of first metal conductive sheets 2031. Please refer to... Figure 7As shown in the illustrated embodiment of the present invention, the first elastic mating portions 2121 of the plurality of first conductive terminals 212 are arranged in a first row L1, and the first cable connecting portions 2122 of the plurality of first conductive terminals 212 are arranged in a second row L2. The first cable connecting portions 2122 of the plurality of first conductive terminals 212 are disposed on the first insulating block 211 to facilitate connection with the first cable 41.

[0057] In the illustrated embodiment of the present invention, the plurality of first conductive terminals 212 include a plurality of first signal terminals S1, a plurality of second signal terminals S2, and a plurality of first ground terminals G1, wherein adjacent first signal terminals S1 and second signal terminals S2 form a first differential pair DP1, and a first ground terminal G1 is provided on each of the adjacent sides of the first differential pair DP1. In the illustrated embodiment of the present invention, the first ground terminal G1 is provided with two forked first elastic mating portions 2121. This arrangement ensures that, at the positions corresponding to the first elastic mating portions 2121 of the first signal terminals S1 and S2, the width of the two first elastic mating portions 2121 of the first ground terminal G1 is generally not less than (i.e., greater than or equal to, the same below) the width of the first elastic mating portion 2121 of the first signal terminal S1, and the width of the two first elastic mating portions 2121 of the first ground terminal G1 is generally not less than the width of the first elastic mating portion 2121 of the second signal terminal S2, thereby providing a better shielding effect. In the embodiment illustrated in the present invention, both the first signal terminal S1 and the second signal terminal S2 have the first cable connection portion 2122, while the first grounding terminal G1 does not have the first cable connection portion 2122.

[0058] Please combine Figure 5 as well as Figure 6As shown in the illustrated embodiment of the present invention, the first terminal module 21 further includes a first metal sheet 213 and a first insulating strip 214 formed on the first metal sheet 213, wherein the plurality of first grounding terminals G1 are integrally formed with the first metal sheet 213 (e.g., stamped). The plurality of first grounding terminals G1 are connected together with the first metal sheet 213 to increase the grounding area. The first metal sheet 213 includes a first base 2131 and a first grounding portion 2132 that is bent upward and protrudes from both sides of the first base 2131. Correspondingly, the insulating body 1 is also provided with a plurality of first slots 18. In the illustrated embodiment of the present invention, the plurality of first slots 18 are a plurality of through holes penetrating the mating surface 12 and the first surface 11. In the illustrated embodiment of the present invention, the shape of the through holes is rectangular; of course, in other embodiments, the through holes can also be other shapes, which will not be described in detail here. The first grounding portion 2132 is exposed from the first slot 18 to the mating surface 12 of the insulating body 1 to contact the outer metal shell 5.

[0059] The second terminal module 22 includes a second insulating block 221 and a plurality of second conductive terminals 222 fixed to the second insulating block 221. In the embodiment illustrated in the present invention, the plurality of second conductive terminals 222 are embedded in the second insulating block 221. Of course, those skilled in the art will understand that the plurality of second conductive terminals 222 can also be fixed to the second insulating block 221 by other means (e.g., assembly). In another embodiment of the present invention, the insulating body 1 can also be fixed to the first terminal module 21 and the second terminal module 22 by secondary molding.

[0060] The plurality of second conductive terminals 222 are arranged at intervals along a first direction A1-A1 (e.g., left-right direction). Each second conductive terminal 222 includes a second elastic mating portion 2221, and at least a portion of the second conductive terminal 222 includes a second cable connection portion 2222. Please refer to... Figure 9As shown by the dashed lines in the lower middle part, in the embodiment illustrated in the present invention, each second conductive terminal 222 is axially symmetrical. For example, the center line of the second elastic mating portion 2221 is aligned with the center line of the second cable connection portion 2222. The second elastic mating portion 2221 extends cantileveredly out of the second insulating block 221. The second elastic mating portion 2221 extends downward out of the first surface 11 to abut against the plurality of second metal conductive sheets 2032. In the embodiment illustrated in the present invention, the second elastic mating portions 2221 of the plurality of second conductive terminals 222 are arranged in a third row L3, and the second cable connection portions 2222 of the plurality of second conductive terminals 222 are arranged in a fourth row L4. The first row L1, the second row L2, the third row L3, and the fourth row L4 are parallel to each other. The first elastic mating portion 2121, the first cable connection portion 2122, the second elastic mating portion 2221, and the second cable connection portion 2222 are arranged sequentially along a second direction A2-A2 perpendicular to the first direction A1-A1. The first cable connection portions 2122 of the plurality of first conductive terminals 212 are flush with the second cable connection portions 2222 of the plurality of second conductive terminals 222. "Flush" means that the surfaces of the first cable connection portions 2122 and the second cable connection portions 2222 on the same side are approximately at the same height, but slight height adjustments are permissible, such as due to manufacturing process tolerances, as long as these tolerances are within a reasonable range; or due to adaptive height adjustments to accommodate different cables. For example, in one embodiment of the invention, the cable can be a cable with a specification between AWG 28 and AWG 40. Taking AWG 32 cable as an example, it is considered acceptable as long as its diameter is within a reasonable range. To accommodate this AWG 32 cable, the heights of the first cable connection portions 2122 and the second cable connection portions 2222 may need to be slightly adjusted. Because this adjustment is small, the first cable connection portions 2122 and the second cable connection portions 2222 are still considered flush. The second cable connection portion 2222 of the plurality of second conductive terminals 222 is disposed on the second insulating block 221 so as to be connected to the second cable 42.

[0061] Please combine Figure 7As shown in the illustrated embodiment of the present invention, the plurality of second conductive terminals 222 include a plurality of third signal terminals S3, a plurality of fourth signal terminals S4, and a plurality of second ground terminals G2. Adjacent third signal terminals S3 and fourth signal terminals S4 form a second differential pair DP2, and a second ground terminal G2 is provided on each of the adjacent sides of the second differential pair DP2. In the illustrated embodiment of the present invention, the second ground terminal G2 has two forked second elastic mating portions 2221. This arrangement ensures that, at the positions corresponding to the second elastic mating portions 2221 of the third signal terminals S3 and the fourth signal terminals S4, the width of the two second elastic mating portions 2221 of the second ground terminal G2 is generally not less than the width of the second elastic mating portion 2221 of the third signal terminals S3, and the width of the two second elastic mating portions 2221 of the second ground terminal G2 is generally not less than the width of the second elastic mating portion 2221 of the fourth signal terminals S4, thereby providing a better shielding effect.

[0062] Please combine Figure 5 as well as Figure 6 As shown in the illustrated embodiment of the present invention, the second terminal module 22 further includes a second metal sheet 223 and a second insulating strip 224 formed on the second metal sheet 223, wherein the plurality of second grounding terminals G2 are integrally formed with the second metal sheet 223 (e.g., stamped). The plurality of second grounding terminals G2 are connected together with the second metal sheet 223 to increase the grounding area. The second metal sheet 223 includes a second base 2231 and second grounding portions 2232 that are bent upward and protruding from both sides of the second base 2231. Correspondingly, the insulating body 1 is also provided with a plurality of second slots 19. In the illustrated embodiment of the present invention, the plurality of second slots 19 are a plurality of openings penetrating the mating surface 12 and the first surface 11. In the illustrated embodiment of the present invention, the openings extend rearward through the rear end face of the insulating body 1; of course, in other embodiments, the second slots 19 may also be configured with a shape and structure similar to the first slots 18, which will not be described in detail here. The second grounding portion 2232 is exposed from the second slot 19 onto the mating surface 12 of the insulating body 1 to contact the outer metal housing 5. In the embodiment illustrated in the present invention, both the first grounding portion 2132 and the second grounding portion 2232 are provided with an arc-shaped notch on the outer side to facilitate better fixation to the outer metal housing 5 by welding or other means.

[0063] In the embodiment illustrated in the present invention, the first terminal module 21 and the second terminal module 22 are identical, thereby enabling the sharing of parts and reducing costs.

[0064] Please combine Figure 8 as well as Figure 9 As shown in the illustrated embodiment of the present invention, the second cable 42 located between two adjacent first cables 41 is positioned exactly in the middle of these two first cables 41; the first cable 41 located between two adjacent second cables 42 is positioned exactly in the middle of these two second cables 42. This arrangement ensures that all first cables 41 and all second cables 42 have the same spacing relative to each other.

[0066] Similarly, each second cable 42 is a coaxial cable, comprising a second core 421, a second insulating layer 422 wrapped around the second core 421, a second shielding layer 423 wrapped around the second insulating layer 422, and a second insulating sheath (not shown) sleeved on the second shielding layer 423. The second core 421 is used to connect (e.g., weld) to the second cable connection portion 2222 of the conductive terminal 222 of the second cable. The second shielding layer 423 is connected to the second metal sheet 223. Preferably, the second shielding layer 423 is welded to the second metal sheet 223.

[0067] In the embodiment illustrated in the present invention, although the lengths of the plurality of first cables 41 and the plurality of second cables 42 are different, the plurality of first cables 41 and the plurality of second cables 42 are all located on the same layer. The first cable connection portions 2122 of the plurality of first conductive terminals 212 and the second cable connection portions 2222 of the plurality of second conductive terminals 222 are staggered along the second direction A2-A2 to improve the convenience of arrangement and facilitate connection with the corresponding cables.
