Of course, in other embodiments of the present application, the second protruding portions 632 can also abut the second shielding layer 523 of the second cable 52 to further improve the grounding shielding effect while fixing the second cable 52.

[0149] The second shielding cover plate 64 is mounted on the second receiving groove 1214 to cover the second through hole 1217, thereby improving the shielding effect.

[0150] In the illustrated embodiment of the present application, the first electrical connector 100 further comprises a second grounding cable 54 in contact with the second shielding cover plate 64.

[0151] In assembling the first electrical connector 100, first, the first insulating fixing block 21 is fixed in the first filling groove 1123 and the second insulating fixing block 22 is fixed in the second filling groove 1223.

[0152] Then, the first terminal module 31a and the second terminal module 32a are mounted in the corresponding first terminal module mounting slot 113 and second terminal module mounting slot 123 from back to front along the first direction A1-A1. At this time, the first fixing block 331 and the second fixing block 332 are clamped in the corresponding first terminal module mounting slot 113, so that the first fixed part 311 of the first conductive terminal 31 is arranged in the first terminal module mounting slot 113 to avoid short circuit caused by contact with the first conductive shell 11.

The second contact arm 320 of the third signal terminal S3 at least partially extends into the third slot 221 of the second insulating fixing block 22. The second contact arm 320 of the fourth signal terminal S4 at least partially extends into the fourth slot 222 of the second insulating fixing block 22. At this time, the first tail part 313 of the first conductive terminal 31 is exposed backward in the first mounting slot 1116, and the second tail part 323 of the second conductive terminal 32 is exposed backward in the second mounting slot 1216.

[0153] Then, the first cable 51 and the second cable 52 are inserted into the corresponding first mounting slot 1116 and second mounting slot 1216 from back to front along the first direction A1-A1; or the first cable 51 and the second cable 52 are arranged in the corresponding first mounting slot 1116 and second mounting slot 1216 along the second direction A2-A2. The first core 511 of the first cable 51 is in contact with the first tail part 313 of the first conductive terminal 31, and the second core 521 of the second cable 52 is in contact with the second tail part 323 of the second conductive terminal 32.

Preferably, in an embodiment of the present application, the first core 511 of the first cable 51 is welded and fixed with the first tail 313 of the first conductive terminal 31, and the second core 521 of the second cable 52 is welded and fixed with the second tail 323 of the second conductive terminal 32.

[0155] In order to better implement welding, in an embodiment of the present application, a first clamp (not shown) extends into the first mounting recess 1110 to support the first cable 51, and a second clamp (not shown) is inserted into the first through hole 1117 along the second direction A2-A2 and abuts against the first tail 313 of the first conductive terminal 31. At this time, the first tail 313 of the first conductive terminal 31 and the first core 511 of the first cable 51 are clamped between the first clamp and the second clamp, thereby improving the contact reliability of the first tail 313 of the first conductive terminal 31 and the first core 511 of the first cable 51 and improving the welding yield.

[0156] Similarly, in order to better implement welding, in an embodiment of the present application, a third clamp (not shown) extends into the second mounting recess 1210 to support the second cable 52, and a fourth clamp (not shown) is inserted into the second through hole 1217 along the second direction A2-A2 and abuts against the second tail 323 of the second conductive terminal 32. At this time, the second tail 323 of the second conductive terminal 32 and the second core 521 of the second cable 52 are clamped between the third clamp and the fourth clamp, thereby improving the contact reliability of the second tail 323 of the second conductive terminal 32 and the second core 521 of the second cable 52 and improving the welding yield.

[0157] After welding is completed, the first clamp, the second clamp, the third clamp, and the fourth clamp are removed.

[0158] Then, the first shielding sheet 61 and the first shielding cover plate 62 are installed on the first conductive shell 11, and the second shielding sheet 63 and the second shielding cover plate 64 are installed on the second conductive shell 12. The first shielding sheet 61 replaces the first clamp to fill the position of the first clamp when the first cable 51 is welded with the first conductive terminal 31, avoiding the influence of losing abutment of the first cable 51 due to the removal of the first clamp. The first shielding cover plate 62 is accommodated in the first accommodation groove 1114 to shield the first through hole 1117, improving the shielding effect.

[0159] Similarly, the second shielding sheet 63 replaces the third clamp to fill the position of the third clamp when the second cable 52 is welded with the second conductive terminal 32, avoiding the influence of losing abutment of the second cable 52 due to the removal of the third clamp. The second shielding cover plate 64 is accommodated in the second accommodation groove 1214 to shield the second through hole 1217, improving the shielding effect.

[0160] Then, the first grounding sheet 41 and the second grounding sheet 42 are respectively installed on the first conductive shell 11 and the second conductive shell 12.

[0161] Then, the first conductive shell 11 and the second conductive shell 12 are attached together; the first base 111 and the second base 121 correspond to each other in up and down; the first protruding part 112 and the second protruding part 122 correspond to each other in up and down.

In the second direction A2-A2, the first shielding sheet 61 and the second shielding sheet 63 are located between the plurality of first conductive terminals 31 and the plurality of second conductive terminals 32 to reduce the crosstalk between the first conductive terminals 31 and the second conductive terminals 32. In addition, in order to further increase the bonding force of the first conductive shell 11 and the second conductive shell 12, the first conductive shell 11 and the second conductive shell 12 are welded at the joint position. For example, please refer to Figure 9As shown, the first conductive shell 11 is provided with a first solder groove 11a recessed upward at the joint position, and the second conductive shell 12 is provided with a second solder groove 12a recessed downward at the joint position. The first solder groove 11a and the second solder groove 12a at the corresponding positions are connected, thereby facilitating the filling of solder in the first solder groove 11a and the second solder groove 12a, and achieving the soldering fixation of the first conductive shell 11 and the second conductive shell 12. After the fixation of the first conductive shell 11 and the second conductive shell 12, the first receiving slot 101 for accommodating the first docking module 300 is formed between the first protruding part 112 and the second protruding part 122.

[0205] Similarly, the second mounting cavity 50a21 provided by the shielding housing 500 for mounting the second electrical connector 200 is much larger than the space occupied by the second electrical connector 200 itself.
