[0105] Specifically, please combine Figure 5As shown, the insulating body 1 extends along a first direction XX and a second direction YY, wherein the first direction XX is perpendicular to the second direction YY. The insulating body 1 includes a first sidewall 11 extending along the second direction YY, a second sidewall 12 extending along the second direction YY, a first endwall 13 connecting one end of the first sidewall 11 and one end of the second sidewall 12, a second endwall 14 connecting the other end of the first sidewall 11 and the other end of the second sidewall 12, and a mating space 10 formed at least by the first sidewall 11, the second sidewall 12, the first endwall 13, and the second endwall 14.

[0106] The plurality of cable conductive terminals 2 include a plurality of first cable conductive terminals 21 arranged in a first row L1 along the second direction YY and a plurality of second cable conductive terminals 22 arranged in a second row L2 along the second direction YY. The plurality of first cable conductive terminals 21 in the first row L1 and the plurality of second cable conductive terminals 22 in the second row L2 are arranged in two rows spaced apart along the first direction XX, and the plurality of first cable conductive terminals 21 in the first row L1 and the plurality of second cable conductive terminals 22 in the second row L2 are staggered in the first direction XX to reduce interference between adjacent conductive terminals. In one embodiment of the present invention, the plurality of first cable conductive terminals 21 in the first row L1 and the plurality of second cable conductive terminals 22 in the second row L2 are arranged in two parallel rows.

[0107] Specifically, please combine Figure 6 As shown, each of the first cable conductive terminals 21 includes a generally U-shaped first insertion portion 211 and a first mounting portion 212 extending from the first insertion portion 211.

In other words, the first mounting portions 212 of the plurality of first cable conductive terminals 21 and the second mounting portions 222 of the plurality of second cable conductive terminals 22 are approximately at the same height. This arrangement facilitates subsequent connection (e.g., welding) of the cable 3 to the first mounting portions 212 and the second mounting portions 222. "Flush" means that the surfaces of the first mounting portions 212 and the second mounting portions 222 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 the tolerance is within a reasonable range; or due to adaptive height adjustments to accommodate different cables. For example, in one embodiment of the present invention, the cable can be a cable with a specification between AWG 28 and AWG 40. Taking AWG 32 as an example, it is considered acceptable as long as its diameter is within a reasonable range. To accommodate the AWG 32 cable, the heights of the first mounting portion 212 and the second mounting portion 222 may need to be slightly adjusted. Since this adjustment is minor, the first mounting portion 212 and the second mounting portion 222 are still considered flush. In the embodiment illustrated in the present invention, the bending direction of the first mounting portion 212 is opposite to the bending direction of the second mounting portion 222. This configuration allows the first cable conductive terminal 21 and the second cable conductive terminal 22 to share components, thereby saving costs.

[0110] Please combine Figure 9 As shown, in the first embodiment of the present invention, both the first cable conductive terminal 21 and the second cable conductive terminal 22 are centrally symmetrical structures. That is, the center surface of the first insertion portion 211 of each first cable conductive terminal 21 is aligned with the center surface of the first mounting portion 212 of the first cable conductive terminal 21; the center surface of the second insertion portion 221 of each second cable conductive terminal 22 is aligned with the center surface of the second mounting portion 222 of the second cable conductive terminal 22.

[0111] The plurality of cables 3 includes a plurality of first cables 31 connected to the plurality of first mounting portions 212 and a plurality of second cables 32 connected to the plurality of second mounting portions 222. Please refer to Figures 7 to 10 As shown in the illustrated embodiment of the present invention, the plurality of first cables 31 are arranged at intervals along the second direction YY, and the plurality of second cables 32 are arranged at intervals along the second direction YY. A second cable 32 is provided between any two adjacent first cables 31, and a first cable 31 is provided between any two adjacent second cables 32. Although the lengths of the first cables 31 and the second cables 32 are different, since the plurality of first mounting portions 212 of the conductive terminals 21 of the plurality of first cables and the plurality of second mounting portions 222 of the conductive terminals 22 of the plurality of second cables are located at the same height, the first cables 31 and the second cables 32 can still be located at the same height after being arranged in a staggered manner. This arrangement is advantageous in reducing the overall height of the cable connector 100.

[0112] Please combine Figure 9 As shown in the illustrated embodiment of the present invention, the second cable 32 located between two adjacent first cables 31 is positioned exactly in the middle of the two first cables 31, and the first cable 31 located between two adjacent second cables 32 is positioned exactly in the middle of the two second cables 32. This arrangement ensures that all first cables 31 and all second cables 32 have a uniform spacing between them.

[0113] To better locate the first cable 31 and the second cable 32, please refer to... Figure 4 as well as Figure 7As shown, the cable connector 100 further includes a first cable positioning block 61 and a second cable positioning block 62.

Those skilled in the art will understand that the first cable positioning block 61 and / or the second cable positioning block 62 can be integrally formed with the insulating body 1; or the first cable positioning block 61 and / or the second cable positioning block 62 can also be assembled and fixed with the insulating body 1. Of course, in other embodiments, the second cable positioning block 62 can also be provided with a plurality of third positioning grooves (not shown) for positioning the plurality of second cables 32 to improve the positioning accuracy of the second cables 32. The first cable positioning block 61 and the second cable positioning block 62 are collectively referred to as positioning blocks, and the first positioning groove 611, the second positioning groove 621 and the third positioning groove are collectively referred to as positioning grooves.

[0114] In the embodiment illustrated in the present invention, the upper surface of the positioning block is higher than the first mounting portion 212 and the second mounting portion 222. With this configuration, the positioning groove can better ensure the welding position of the first cable 31 to the first mounting portion 212 and the welding position of the second cable 32 to the second mounting portion 222 while positioning the first cable 31 and / or the second cable 32, thereby improving the welding quality.

[0116] Similarly, each second cable 32 is a coaxial cable, comprising a second core 321, a second insulating layer 332 wrapped around the second core 321, a second insulating braid 323 wrapped around the second insulating layer 322, and a second insulating sheath 324 sleeved on the second insulating braid 323. The second core 321 is used to weld and fix to the second mounting portion 222 of the conductive terminal 22 of the second cable.

[0117] Please combine Figure 3 as well as Figure 4 As shown in the illustrated embodiment of the present invention, the grounding housing 4 is a one-piece structure made of metal sheet. The grounding housing 4 includes an isolation piece 40 extending along the second direction YY and located in the first direction XX between the first cable conductive terminals 21 of the first row L1 and the second cable conductive terminals 22 of the second row L2; a first grounding portion 41 fixed to the first end wall 13; a second grounding portion 42 fixed to the second end wall 14; a first grounding connecting piece 43 connecting the first grounding portion 41 and the second grounding portion 42; and a second grounding connecting piece 44 connecting the first grounding portion 41 and the second grounding portion 42 and parallel to the first grounding connecting piece 43.

The isolation piece 40 is vertically disposed between a plurality of first cable conductive terminals 21 of the first row L1 and a plurality of second cable conductive terminals 22 of the second row L2. In the illustrated embodiment of the present invention, the insulating plate 40 is formed by bending the first grounding connection plate 43. The first grounding connection plate 43, the second grounding connection plate 44, the insulating plate 40, the first grounding portion 41, and the second grounding portion 42 are a one-piece structure. Please refer to... Figure 1 As shown, the isolation plate 40 is located in the docking space 10, which divides the docking space 10 into a first docking space 101 located on one side of the isolation plate 40 and a second docking space 102 located on the other side of the isolation plate 40. The first docking space 101 is used to accommodate the first island portion 71 of the board-end connector 200, and the second docking space 102 is used to accommodate the second island portion 72 of the board-end connector 200.

The grounding housing 4 includes an isolation member 49, which includes the isolation plate 40 and the first grounding connection piece 43.

[0118] To further improve the grounding shielding effect, in the embodiment illustrated in the present invention, the first insulating braided mesh 313 of the first cable 31 is in contact with the first grounding connecting piece 43, and the second insulating braided mesh 323 of the second cable 32 is in contact with the second grounding connecting piece 44.

Of course, in other embodiments, the first insulating braided mesh 313 of the first cable 31 overlaps with the first grounding connecting piece 43, and the second insulating braided mesh 323 of the second cable 32 overlaps with the second grounding connecting piece 44. In addition, to prevent the welding gap between the first grounding connection piece 43 and the second grounding connection piece 44 and the first insulating braided mesh 313 and the second insulating braided mesh 323 from being too large due to their contact with the first insulating skin 314 and the second insulating skin 324, the first grounding connection piece 43 and / or the second grounding connection piece 44 may be provided with a clearance portion (not shown) that is offset away from the first insulating skin 314 and / or the second insulating skin 324.

[0119] Please combine Figure 2 as well as Figure 4 As shown, the metal cover 5 is mounted on the insulating body 1 and fixed to the grounding housing 4 to improve the grounding shielding effect. The metal cover 5 includes a perforated groove 50, in which the first insulating braided mesh 313 of the first cable 31 and the second insulating braided mesh 323 of the second cable 32 are at least partially exposed. This arrangement facilitates the inspection of welding quality through the perforated groove 50 and provides welding space when repair welding is required.

[0120] In the first embodiment illustrated in the present invention, the first cable conductive terminal 21, the second cable conductive terminal 22, and the grounding housing 4 are embedded in the insulating body 1 to improve the overall structural strength. The second grounding connection piece 44 protrudes from the insulating body 1 to facilitate welding with the second insulating braid 323 of the second cable 32 and to the metal cover 5.

[0121] Figures 14 to 16A second embodiment of the cable connector 100 of the present invention is disclosed, wherein the main difference between the cable connector 100 in the second embodiment and the cable connector 100 in the first embodiment lies in the bending direction of the first mounting portion 212 of the first cable conductive terminal 21 and the second mounting portion 222 of the second cable conductive terminal 22. Specifically, in the second embodiment of the cable connector 100 of the present invention, the bending direction of the first mounting portion 212 is the same as the bending direction of the second mounting portion 222.

[0122] Figures 23 to 30 A third embodiment of the cable connector 100 of the present invention is disclosed, wherein the main difference between the cable connector 100 in the third embodiment and the cable connector 100 in the first embodiment lies in the shape of the first cable conductive terminal 21 and the second cable conductive terminal 22. Specifically, please refer to... Figure 26 as well as Figure 29 As shown, in a third embodiment of the cable connector 100 of the present invention, the plurality of first cable conductive terminals 21 include a plurality of first signal terminals S1 and a plurality of second signal terminals S2, wherein adjacent first signal terminals S1 and second signal terminals S2 form a first differential pair DP1 (Differential Pair). The plurality of second cable conductive terminals 22 include a plurality of third signal terminals S3 and a plurality of fourth signal terminals S4, wherein adjacent third signal terminals S3 and fourth signal terminals S4 form a second differential pair DP2 (Differential Pair). The first differential pair DP1 and the second differential pair DP2 are staggered in the first direction XX.

[0123] The first insertion portion 211 of the first cable conductive terminal 21 is U-shaped. The first cable conductive terminal 21 includes a first deflection portion 213 connecting the first insertion portion 211 and the first mounting portion 212, such that the center plane of the first insertion portion 211 and the center plane of the first mounting portion 212 are misaligned. In the first differential pair DP1, the first deflection portion 213 of the first signal terminal S1 is deflected away from the second signal terminal S2, and the first deflection portion 213 of the second signal terminal S2 is deflected away from the first signal terminal S1. This configuration ensures that the distance between the first mounting portion 212 of the first signal terminal S1 and the first mounting portion 212 of the second signal terminal S2 along the second direction YY is greater than the distance between the first insertion portion 211 of the first signal terminal S1 and the first insertion portion 211 of the second signal terminal S2 along the second direction YY.

[0124] Please combine Figure 26As shown in the illustrated embodiment of the present invention, a first cable 31 corresponding to the second differential pair DP2 has its center line located at the exact center of the second differential pair DP2. Similarly, a second cable 32 corresponding to the first differential pair DP1 has its center line located at the exact center of the second differential pair DP1.

[0125] Similarly, the second insertion portion 221 of the second cable conductive terminal 22 is U-shaped. The second cable conductive terminal 22 includes a second oblique portion 223 connecting the second insertion portion 221 and the second mounting portion 222, such that the center plane of the second insertion portion 221 and the center plane of the second mounting portion 222 are misaligned. In the second differential pair DP2, the second oblique portion 223 of the third signal terminal S3 is obliquely directed away from the fourth signal terminal S4, and the second oblique portion 223 of the fourth signal terminal S4 is obliquely directed away from the third signal terminal S3. This arrangement ensures that the distance between the second mounting portion 222 of the third signal terminal S3 and the second mounting portion 222 of the fourth signal terminal S4 along the second direction YY is greater than the distance between the second insertion portion 221 of the third signal terminal S3 and the second insertion portion 221 of the fourth signal terminal S4 along the second direction YY.

[0126] Please combine Figures 23 to 30 As shown, in the third embodiment of the cable connector 100 of the present invention, by providing the first cable conductive terminal 21 and the second cable conductive terminal 22 as described above, the distance between the plug-in portions can be shortened and the distance between the differential pairs can be increased, thereby improving the integrity of the differential pairs when transmitting high-frequency signals.

[0127] Figures 31 to 37 Another embodiment of the connector assembly of the present invention is disclosed, wherein the board-end connector 200 does not have an isolation terminal 83. Figures 31 to 37A fourth embodiment of the cable connector 100 of the present invention is disclosed, wherein the main difference between the cable connector 100 in the fourth embodiment and the cable connector 100 in the third embodiment lies in the structure of the grounding housing 4. Specifically, in the fourth embodiment of the cable connector 100 of the present invention, the grounding housing 4 includes at least one first grounding terminal G1 and at least one second grounding terminal G2 integrally extending from the grounding housing 4. The first grounding terminal G1 is located in the first row L1 and is located beside the first differential pair DP1, and the second grounding terminal G2 is located in the second row L2 and is located beside the second differential pair DP2. The width of the first grounding terminal G1 and / or the second grounding terminal G2 along the second direction YY can be respectively set to be the same as the width of the signal terminal. In the embodiment illustrated in the present invention, the pitch between any two adjacent terminals of the first grounding terminal G1, the first signal terminal S1, and the second signal terminal S2 is equal; the pitch between any two adjacent terminals of the second grounding terminal G2, the third signal terminal S3, and the fourth signal terminal S4 is also equal.

[0128] Please combine Figures 38 to 40 As shown, in the fourth embodiment of the cable connector 100 of the present invention, the widths of the first grounding terminal G1 and / or the second grounding terminal G2 along the second direction YY can be respectively set to be greater than the width of the signal terminal. For example, the width of the first grounding terminal G1 along the second direction YY is greater than or equal to twice the width of the first signal terminal S1, and the width of the first grounding terminal G1 along the second direction YY is greater than or equal to twice the width of the second signal terminal S2. The width of the second grounding terminal G2 along the second direction YY is greater than or equal to twice the width of the third signal terminal S3, and the width of the second grounding terminal G2 along the second direction YY is greater than or equal to twice the width of the fourth signal terminal S4. With this configuration, by appropriately increasing the widths of the first grounding terminal G1 and the second grounding terminal G2, the signal terminals can be better shielded, thereby improving the signal transmission quality.

[0129] Please combine Figures 35 to 37As shown in the illustrated embodiment of the present invention, there are multiple first grounding terminals G1, and two first grounding terminals G1 are provided between two adjacent first differential pairs DP1, forming a first grounding terminal group GP1. Similarly, there are multiple second grounding terminals G2, and two second grounding terminals G2 are provided between two adjacent second differential pairs DP2, forming a second grounding terminal group GP2. The first grounding terminal group GP1 and the first differential pairs DP1 are arranged alternately, and the second grounding terminal group GP2 and the second differential pairs DP2 are arranged alternately.

[0130] Each of the first grounding terminal groups GP1 includes a first base 45, a first branch 461 connected to the first base 45, and a second branch 462 connected to the first base 45, wherein the two first grounding terminals G1 in the first grounding terminal group GP1 are respectively connected to the first branch 461 and the second branch 462.

[0131] Similarly, each of the second grounding terminal groups GP2 includes a second base 47, a third branch 481 connected to the second base 47, and a fourth branch 482 connected to the second base 47, wherein the two second grounding terminals G2 in the second grounding terminal group GP2 are respectively connected to the third branch 481 and the fourth branch 482.

[0132] Furthermore, those skilled in the art will understand that the at least one first grounding terminal G1 is a plurality of terminals, and only one first grounding terminal G1 is provided between two adjacent first differential pairs DP1; the at least one second grounding terminal G2 is a plurality of terminals, and only one second grounding terminal G2 is provided between two adjacent second differential pairs DP2.

[0133] Figures 41 to 44 The fifth embodiment of the cable connector 100 of the present invention is disclosed. The cable connector 100 in the fifth embodiment differs from the cable connector 100 in the fourth embodiment in the structure of the first signal terminal S1, the second signal terminal S2, the third signal terminal S3 and the fourth signal terminal S4, as well as the arrangement of the first cable 31 and the second cable 32.

[0134] Specifically, the first cable conductive terminals 21 are all centrally symmetrical, that is, the center surface of the first insertion portion 211 of the first cable conductive terminal 21 is aligned with the center surface of the first mounting portion 212 of the first cable conductive terminal 21; the center surface of the second insertion portion 221 of the second cable conductive terminal 22 is aligned with the center surface of the second mounting portion 222 of the second cable conductive terminal 22. This arrangement can reduce or even avoid the misalignment of the first mounting portion 212 of the first cable conductive terminal 21 relative to the first insertion portion 211 of the first cable conductive terminal 21; it can also reduce or even avoid the misalignment of the second mounting portion 222 of the second cable conductive terminal 22 relative to the second insertion portion 221 of the second cable conductive terminal 22, thereby helping to reduce the manufacturing difficulty of the cable conductive terminals.

[0135] Please combine Figures 41 to 44 As shown, the widths of the first grounding terminal G1 and / or the second grounding terminal G2 along the second direction YY can be set to be greater than the width of the signal terminal. For example, the width of the first grounding terminal G1 along the second direction YY is greater than or equal to twice the width of the first signal terminal S1, and the width of the first grounding terminal G1 along the second direction YY is greater than or equal to twice the width of the second signal terminal S2. The width of the second grounding terminal G2 along the second direction YY is greater than or equal to twice the width of the third signal terminal S3, and the width of the second grounding terminal G2 along the second direction YY is greater than or equal to twice the width of the fourth signal terminal S4. With this configuration, by appropriately increasing the widths of the first grounding terminal G1 and the second grounding terminal G2, better shielding of the signal terminals can be achieved, thereby improving signal transmission quality.

[0136] The width occupied by the first differential pair DP1 of the first cable conductive terminal 21 along the second direction YY is approximately the same as the width occupied by the second ground terminal G2 corresponding to the first differential pair DP1 along the second direction YY. With this configuration, when the first cable 31 is connected to the first differential pair DP1, the first cable 31 can fully utilize the width of the second ground terminal G2, thereby avoiding interference between the first cable 31 and the adjacent second cable 32. In other words, please refer to... Figures 41 to 44As shown, in the fifth embodiment of the cable connector 100 of the present invention, two first cables 31 connected to the first differential pair DP1 constitute a first group, and two second cables 32 connected to the second differential pair DP2 constitute a second group, wherein the first cables 31 of the first group and the second cables 32 of the second group are arranged alternately along the second direction YY. In the fourth embodiment of the cable connector 100 of the present invention, the grounding housing 4 does not have an integrally formed isolation plate 40; instead, the grounding housing 4 is provided with at least one first grounding terminal G1 and at least one second grounding terminal G2. By providing the first grounding terminal G1 on at least one side of the first differential pair DP1 on the first row L1, the integrity of the first differential pair DP1 when transmitting high-frequency signals is improved; by providing the second grounding terminal G2 on at least one side of the second differential pair DP2 on the second row L2, the integrity of the second differential pair DP2 when transmitting high-frequency signals is improved.

[0137] Those skilled in the art can understand. Figure 32 as well as Figure 33 The board-end connector 200 mentioned above can also be configured as follows: Figure 21 as well as Figure 22 The isolation terminals 83 shown can form good protection by connecting the isolation terminals 83 to the ground plate (not shown) of the circuit board 300, and further improve the integrity of the first differential pair DP1 and the second differential pair DP2 when transmitting high-frequency signals.

[0138] When the cable connector 100 mates with the board connector 200, the first island portion 71 and the second island portion 72 of the board connector 200 are received in the mating space 10 of the cable connector 100. The first insertion portion 211 of the cable connector 100 contacts the first mating portion 811 of the board connector 200, and the second insertion portion 221 of the cable connector 100 contacts the second mating portion 821 of the board connector 200. When the cable connector 100 in the first to third embodiments mates with the board connector 200, the first island portion 71 of the board connector 200 is received in the first mating space 101 of the cable connector 100, the second island portion 72 of the board connector 200 is received in the second mating space 102 of the cable connector 100, and the spacer plate 40 of the cable connector 100 is inserted into the slot 73 of the board connector 200. The isolation plate 40 is inserted into the slot 8331 of the isolation terminal 83 to contact the abutment portion 833 of the isolation terminal 83.

[0139] Compared to existing technologies, the present invention improves the arrangement of the first cable conductive terminals 21 and the second cable conductive terminals 22 in the first row L1 and the second row L2 in the first direction XX by staggering the arrangement of the first mounting portions 212 of the first cable conductive terminals 21 and the second mounting portions 222 of the second cable conductive terminals 22 in the first direction XX, and by making the first mounting portions 212 of the first cable conductive terminals 21 and the second mounting portions 222 of the second cable conductive terminals 22 flush. This facilitates connection with the first cable 31 and the second cable 32. In addition, by providing an isolator 49 or a first grounding terminal G1 / second grounding terminal G2 located between the first cable conductive terminals 21 in the first row L1 and the second cable conductive terminals 22 in the second row L2, the cable conductive terminals 2 can be better shielded, crosstalk can be reduced, and signal integrity can be improved.

[0140] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on those skilled in the art. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present invention.
