[0088] Please refer to Figures 11 to 13 As shown, the first cable module 51 includes a first metal strip 511 and a plurality of first cables 512. In the illustrated embodiment of the present utility model, a part of the plurality of first cables 512 passes through the first metal strip 511 to be fixed on the first metal strip 511. Of course, in other embodiments of the present utility model, the first cables 512 can also be fixed to the first metal strip 511 by other means.

[0089] The first cable 512 is provided with a first core wire 5121, a first insulating layer 5122 wrapped around the first core wire 5121, and a first insulating sheath 5123 located outside the first insulating layer 5122.

[0090] In some embodiments of the present utility model, the first cable 512 may also be provided with a first shielding layer between the first insulating layer 5122 and the first insulating sheath 5123. At this time, by bringing the first shielding layer into contact with the first metal strip 511, the first shielding layers of all the first cables 512 can be connected into a whole, which is beneficial to improving the shielding effect.

[0091] In the illustrated embodiment of the present utility model, the first metal strip 511 is provided with a first abutting surface 5110.

The first cable module 51 is installed on the base portion 40, the first metal strip 511 is supported on the first surface 401 of the base portion 40, and the first abutting surface 5110 of the first metal strip 511 abuts against the first positioning surface 4051 of the first positioning block 405 in the second direction A2 - A2 (e.g., the front - back direction) to limit the first cable module 51 in the second direction A2 - A2.

[0092] In the illustrated embodiment of the present utility model, the first abutting surfaces 5110 are all vertical surfaces. By abutting the first abutting surfaces 5110 against the first positioning surfaces 4051, when the first cable module 51 is installed from back to front along the second direction A2-A2, the first positioning surfaces 4051 can position the first cable module 51, thereby avoiding the problem that the first cable module 51 is not properly installed in the second direction A2-A2.

In the illustrated embodiment of the present utility model, the first core wire 5121 of the first cable 512 is configured to be welded and fixed to the first tail portion 313 of the corresponding first conductive terminal 31. In the illustrated embodiment of the present utility model, the height by which the first positioning block 405 protrudes upward from the first rib 403 needs to be reasonably set to ensure that: on the one hand, the height by which the first positioning block 405 protrudes upward from the first rib 403 can reliably block the first abutting surface 5110 of the first metal strip 511; on the other hand, to avoid the first positioning block 405 affecting the welding of the first core wire 5121 of the first cable 512 to the first tail portion 313 of the first conductive terminal 31 due to the height by which it protrudes upward from the first rib 403 being too high. When the height by which the first positioning block 405 protrudes upward from the first rib 403 is too high, the welding torch is likely to touch the first positioning block 405, causing it to melt, affecting the appearance and easily resulting in failure.

[0094] Please refer to Figure 19 and Figure 20 As shown, in the illustrated embodiment of the present utility model, the center of the first core wire 5121 of the first cable 512 is located in the first horizontal plane M1, and the top surface 4052 of the first positioning block 405 is not higher than the first horizontal plane M1. Preferably, the top surface 4052 of the first positioning block 405 is slightly lower than the first horizontal plane M1.

[0100] The second cable module 52 includes a second metal strip 521 and a plurality of second cables 522. In the illustrated embodiment of the present utility model, a part of the plurality of second cables 522 passes through the second metal strip 521 and is fixed to the second metal strip 521. Of course, in other embodiments of the present utility model, the second cables 522 can also be fixed to the second metal strip 521 by other means.

[0101] The second cable 522 is provided with a second core wire 5221, a second insulating layer 5222 wrapped around the second core wire 5221, and a second insulating sheath 5223 located outside the second insulating layer 5222. The second core wire 5221 of the second cable 522 is configured to be electrically connected (e.g., welded) to the second tail 323 of the corresponding second conductive terminal 32.

[0102] In some embodiments of the present utility model, the second cable 522 may further be provided with a second shielding layer between the second insulating layer 5222 and the second insulating sheath 5223. At this time, by bringing the second shielding layer into contact with the second metal strip 521, the second shielding layers of all the second cables 522 can be connected into a whole, which is beneficial to improving the shielding effect.

[0103] In the illustrated embodiment of the present utility model, the second metal strip 521 is provided with a second abutting surface 5210. The second core wire 5221 protrudes forward from the second abutting surface 5210.

The second metal strip 521 is in contact with the metal shielding sheet 42.

[0104] In the illustrated embodiment of the present utility model, the second abutting surfaces 5210 are all vertical surfaces. By abutting the second abutting surface 5210 against the second positioning surface 4061, when the second cable module 52 is installed from back to front along the second direction A2-A2, the second positioning surface 4061 can position the second cable module 52, thus avoiding the problem that the second cable module 52 is not properly installed in the second direction A2-A2. In addition, by supporting the second metal strip 521 on the second surface 402 of the base portion 40, the second cable module 52 can also be positioned along the first direction A1-A1.

[0105] After the second cable module 52 is installed in place, at least a part of the second cable 522 is received in the second cable positioning groove 4074. In the illustrated embodiment of the present utility model, the second core wire 5221 of the second cable 522 is configured to be welded and fixed to the second tail 323 of the corresponding second conductive terminal 32. In the illustrated embodiment of the present utility model, the height by which the second positioning block 406 protrudes downward from the second rib 404 needs to be reasonably set to ensure that, on the one hand, the height by which the second positioning block 406 protrudes downward from the second rib 404 can reliably block the second abutting surface 5210 of the second metal strip 521; on the other hand, to prevent the second positioning block 406 from affecting the welding of the second core wire 5221 of the second cable 522 to the second tail 323 of the second conductive terminal 32 due to its excessive height of protruding downward from the second rib 404. When the height by which the second positioning block 406 protrudes downward from the second rib 404 is too high, the welding torch is likely to touch the second positioning block 406, causing it to melt, affecting the appearance and easily resulting in failure.

[0106] In the illustrated embodiment of the present utility model, the second positioning surfaces 4061 of all the second positioning blocks 406 are located in the same plane to jointly abut against the second abutting surface 5210 of the second metal strip 521, improving the structural strength.

[0107] In the illustrated embodiment of the present utility model, the second metal strip 521 includes a second top wall 5211 and a second bottom wall 5212 opposite to the second top wall 5211.

[0108] More specifically, in the illustrated embodiment of the present utility model, the second top wall 5211 includes a second extended top 5211a at the side end. The second bottom wall 5212 includes a second extended bottom 5212a at the side end. The second metal strip 521 includes a second front-end connecting portion 5213a connecting the front end of the first extended top 5111 and the front end of the second extended bottom 5212a. The second metal strip 521 further includes a second rear-end connecting portion 5214a connecting the rear end of the first extended top 5111 and the rear end of the second extended bottom 5212a. The second extended top 5211a, the second front-end connecting portion 5213a, the second extended bottom 5212a, and the second rear-end connecting portion 5214a enclose a frame shape to increase the structural strength. The second extended top 5211a is supported on the second surface 402 of the base portion 40.

[0109] In addition, the second top wall 5211 includes a second protrusion 5211b extending forward from the second extended top 5211a. The second protrusion 5211b protrudes forward beyond the second front-end connecting portion 5213a, and the second protrusion 5211b is supported on the second surface 402 of the base portion 40. The second metal strip 521 further includes a second extended tail 5215 extending backward and protruding beyond the second rear-end connecting portion 5214a.
