Of course, those skilled in the art will understand that the number of the first positioning blocks 405 and the second positioning blocks 406 can be flexibly adjusted as needed, and this will not be elaborated further in this invention.

[0043] In the embodiment illustrated in the present invention, a first terminal tail mounting groove 4071 is formed between two adjacent first protrusions 403. Each first positioning block 405 has a first positioning surface 4051 located at the rear end of the first terminal tail mounting groove 4071 and a top surface 4052 protruding upward from the first protrusion 403.

[0044] In the embodiment illustrated in the present invention, a first cable positioning groove 4072 is formed between two adjacent first positioning blocks 405, communicating with the first terminal tail mounting groove 4071. The first tail 313 of the first conductive terminal 31 is at least partially received in the corresponding first terminal tail mounting groove 4071 to achieve a certain degree of positioning.

[0045] In the embodiment illustrated in the present invention, the first protrusion 403 extends integrally with the base portion 40, and the first positioning block 405 extends integrally with the corresponding first protrusion 403. The first protrusion 403 and the first positioning block 405 connected together form a stepped shape.

[0046] Similarly, in the embodiment illustrated in the present invention, a second terminal tail mounting groove 4073 is formed between two adjacent second protrusions 404.

[0048] In the embodiment illustrated in the present invention, the second protrusion 404 extends integrally with the base portion 40, and the second positioning block 406 extends integrally with the corresponding second protrusion 404. The connected second protrusion 404 and the second positioning block 406 form a stepped shape.

[0049] Those skilled in the art will understand that, in other embodiments of the present invention, the base portion 40 may also be formed on the insulating body 1.

[0050] Referring to Figures 11 to 13, 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 invention, the plurality of first cables 512 partially pass through the first metal strip 511 to be fixed to the first metal strip 511. Of course, in other embodiments of the present invention, the first cables 512 may also be fixed to the first metal strip 511 in other ways.

[0051] The first cable 512 has 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. The first core wire 5121 of the first cable 512 is configured to be electrically connected (e.g., soldered) to the first tail portion 313 of the corresponding first conductive terminal 31.

[0052] In some embodiments of the present invention, the first cable 512 may also be provided with a first shielding layer located between the first insulating layer 5122 and the first insulating sheath 5123. In this case, the first shielding layers of all the first cables 512 can be connected into a whole by contacting the first shielding layer with the first metal strip 511, thereby improving the shielding effect.

[0053] In the embodiment illustrated in the present invention, the first metal strip 511 has a first abutting surface 5110. The first core wire 5121 protrudes forward from the first abutting surface 5110. The first cable module 51 is mounted on the base portion 40, and the first metal strip 511 is supported on the first surface 401 of the base portion 40. The first abutting surface 5110 of the first metal strip 511 abuts against the first positioning surface 4051 of the first positioning block 405 along the second direction A2-A2 (e.g., the front-to-back direction) to limit the first cable module 51 in the second direction A2-A2. The second direction A2-A2 is perpendicular to the first direction A1-A2. The first metal strip 511 is in contact with the metal shielding sheet 42.

[0054] In the embodiment illustrated in the present invention, the first abutting surface 5110 is always a vertical surface. By abutting the first abutting surface 5110 against the first positioning surface 4051, when the first cable module 51 is installed from back to front along the second direction A2-A2, the first positioning surface 4051 can position the first cable module 51, thereby avoiding the problem of the first cable module 51 not being properly installed in the second direction A2-A2. Additionally, by supporting the first metal strip 511 on the first surface 401 of the base portion 40, the first cable module 51 can also be positioned along the first direction A1-A1.

[0055] After the first cable module 51 is installed in place, the first cable 512 is at least partially housed in the first cable positioning groove 4072. In the embodiment illustrated in the present invention, 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 embodiment illustrated in the present invention, the height of the first positioning block 405 protruding upward from the first protrusion 403 needs to be reasonably set to ensure that: on the one hand, the height of the first positioning block 405 protruding upward from the first protrusion 403 can reliably block the first abutment surface 5110 of the first metal strip 511; on the other hand, it avoids the first positioning block 405 protruding upward from the first protrusion 403 too high, which would affect 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. When the height of the first positioning block 405 protruding upward from the first protrusion 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 causing failure.

[0056] Referring to Figures 19 and 20, in the illustrated embodiment of the present invention, the center of the first core wire 5121 of the first cable 512 is located within 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.

[0057] In the embodiment illustrated in the present invention, the first positioning surfaces 4051 of all the first positioning blocks 405 are located in the same plane so as to abut against the first contact surface 5110 of the first metal strip 511, thereby improving the structural strength.

[0058] Referring to Figures 8 and 11 to 13, in the illustrated embodiment of the present invention, the first metal strip 511 includes a first top wall 5111, a first bottom wall 5112 opposite to the first top wall 5111, a first front end wall 5113 connecting the first top wall 5111 and the first bottom wall 5112, and a first rear end wall 5114 connecting the first top wall 5111 and the first bottom wall 5112. In the illustrated embodiment of the present invention, the first abutment surface 5110 is provided on the first front end wall 5113, and the first bottom wall 5112 is supported on the first surface 401 of the base portion 40.

[0059] More specifically, in the embodiment illustrated in the present invention, the first top wall 5111 includes a first extended top 5111a located at a side end. The first bottom wall 5112 includes a first extended bottom 5112a located at a side end. The first metal strip 511 includes a first front end connecting portion 5113a connecting the front end of the first extended top 5111a and the front end of the first extended bottom 5112a. The first metal strip 511 also includes a first rear end connecting portion 5114a connecting the rear end of the first extended top 5111a and the rear end of the first extended bottom 5112a. The first extended top 5111a, the first front end connecting portion 5113a, the first extended bottom 5112a, and the first rear end connecting portion 5114a form a frame shape to increase structural strength. The first extended bottom 5112a is supported on the first surface 401 of the base portion 40.

[0060] Additionally, the first bottom wall 5112 includes a first protrusion 5112b extending forward from the first extended bottom 5112a. The first protrusion 5112b protrudes forward from the first front end connecting portion 5113a and is supported on the first surface 401 of the base portion 40. The first metal strip 511 also includes a first extended tail 5115 extending rearward from the first rear end connecting portion 5114a. The first extended tail 5115 is configured to contact the first extension 423 of the metal shielding sheet 42. Preferably, the first extended tail 5115 is welded and fixed to the first extension 423 of the metal shielding sheet 42.

[0061] In one embodiment of the present invention, the left and right sides of the first metal strip 511 are symmetrically arranged, and the structure of the other side is described above. The present invention will not repeat the description.

[0062] The second cable module 52 includes a second metal strip 521 and a plurality of second cables 522. In the embodiment illustrated in the present invention, the plurality of second cables 522 partially pass through the second metal strip 521 to be fixed to the second metal strip 521. Of course, in other embodiments of the present invention, the second cables 522 may also be fixed to the second metal strip 521 in other ways.

[0063] The second cable 522 has 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., soldered) to the second tail portion 323 of the corresponding second conductive terminal 32.

[0064] In some embodiments of the present invention, the second cable 522 may also be provided with a second shielding layer located between the second insulating layer 5222 and the second insulating sheath 5223. In this case, the second shielding layers of all the second cables 522 can be connected into a whole by contacting the second shielding layer with the second metal strip 521, thereby improving the shielding effect.

[0065] In the embodiment illustrated in the present invention, the second metal strip 521 is provided with a second abutment surface 5210. The second core wire 5221 protrudes forward from the second abutment surface 5210. The second cable module 52 is mounted on the base portion 40, and the second metal strip 521 is supported on the second surface 402 of the base portion 40. The second abutment surface 5210 of the second metal strip 521 abuts against the second positioning surface 4061 of the second positioning block 406 along the second direction A2-A2 (e.g., the front-to-back direction) to limit the second cable module 52 in the second direction A2-A2. The second metal strip 521 is in contact with the metal shielding sheet 42.

[0066] In the embodiment illustrated in the present invention, the second abutment surface 5210 is always a vertical surface. By abutting the second abutment 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, thereby avoiding the problem of the second cable module 52 not being properly installed in the second direction A2-A2. Additionally, 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.

[0067] After the second cable module 52 is installed, the second cable 522 is at least partially housed in the second cable positioning groove 4074. In the illustrated embodiment of the present invention, the second core wire 5221 of the second cable 522 is configured to be welded and fixed to the second tail portion 323 of the corresponding second conductive terminal 32. In the illustrated embodiment of the present invention, the height of the second positioning block 406 protruding downward from the second protrusion 404 needs to be reasonably set to ensure that: on the one hand, the height of the second positioning block 406 protruding downward from the second protrusion 404 can reliably block the second abutment surface 5210 of the second metal strip 521; on the other hand, it avoids the second positioning block 406 protruding downward from the second protrusion 404 too much, which would affect the welding of the second core wire 5221 of the second cable 522 to the second tail portion 323 of the second conductive terminal 32. When the height of the second positioning block 406 protruding downward from the second protrusion 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 causing failure.

[0068] In the embodiment illustrated in the present invention, the second positioning surfaces 4061 of all the second positioning blocks 406 are located in the same plane so as to abut against the second contact surface 5210 of the second metal strip 521, thereby improving the structural strength.

[0069] In the illustrated embodiment of the present invention, the second metal strip 521 includes a second top wall 5211 and a second bottom wall 5212 opposite to the second top wall 5211. In the illustrated embodiment of the present invention, the second abutment surface 5210 is provided on the second top wall 5211, and the second bottom wall 5212 is supported on the second surface 402 of the base portion 40.

[0070] More specifically, in the embodiment illustrated in the present invention, the second top wall 5211 includes a second extended top 5211a located at a side end. The second bottom wall 5212 includes a second extended bottom 5212a located at a side end. The second metal strip 521 includes a second front end connecting portion 5213a connecting the front end of the first extended top 5111a and the front end of the second extended bottom 5212a. The second metal strip 521 also includes a second rear end connecting portion 5214a connecting the rear end of the first extended top 5111a 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 form a frame shape to increase structural strength. The second extended top 5211a is supported on the second surface 402 of the base portion 40.

[0071] Additionally, the second top wall 5211 includes a second protrusion 5211b extending forward from the second extended top 5211a. The second protrusion 5211b protrudes forward from the second front end connecting portion 5213a and is supported on the second surface 402 of the base portion 40. The second metal strip 521 also includes a second extended tail 5215 extending rearward from the second rear end connecting portion 5214a. The second extended tail 5215 is configured to contact the first extension 423 of the metal shielding sheet 42. Preferably, the second extended tail 5215 is welded and fixed to the first extension 423 of the metal shielding sheet 42.

[0072] In one embodiment of the present invention, the left and right sides of the second metal strip 521 are symmetrically arranged, and the structure of the other side is described above. The present invention will not repeat the description.

[0073] The cable connector 100 of the present invention has a base portion 40, the base portion 40 having a first positioning block 405, the first positioning block 405 having a first positioning surface 4051 located at the rear end of the first terminal tail mounting groove 4071. A first cable module 51 is mounted on the base portion 40. A first metal strip 511 is supported on the first surface 401 of the base portion 40 to position the first cable module 51 in the first direction A1-A1. The first abutting surface 5110 of the first metal strip 511 abuts against the first positioning surface 4051 of the first positioning block 405 along the second direction A2-A2 to limit the first cable module 51 in the second direction A2-A2, thereby improving the process yield.

[0074] The positioning of the second cable module 52 when it is installed on the base 40 is similar to that of the first cable module 51, and will not be described again in this invention.
