Wherein, the butt joint part 11 is formed with a plurality of terminal slots 113 and a plurality of shielding slots 114 penetrating from the front end surface 111 to the rear end surface 112 (for example, along the width direction W), the number of the plurality of terminal slots 113 is twice that of the plurality of shielding slots 114 in the embodiment; the plurality of terminal grooves 113 are arranged substantially in a matrix, the plurality of shield grooves 114 are also arranged substantially in a matrix, and the plurality of terminal grooves 113 and the plurality of shield grooves 114 are arranged so as to be staggered with each other along the longitudinal direction L.
The extension plate 12 is an elongated structure parallel to the length direction L, and the extension plate 12 is formed by extending from the top edge of the rear end surface 112 of the abutting portion 11 along the width direction W. A plurality of fitting grooves 121 are formed in the extension plate 12 in a recessed manner from the end edge thereof, and the fitting grooves 121 are arranged in the longitudinal direction L; the extension plate 12 is formed with a plurality of through holes 122 adjacent to the plurality of fitting grooves 121, respectively, and the plurality of through holes 122 are also arranged along the longitudinal direction L.
The part of each guide post 13 protrudes from the front end surface 111 of the docking portion 11, and the arrangement position of the guide post 13 at the top edge of the docking portion 11 is different from the arrangement position of the guide post 13 at the bottom edge of the docking portion 11.
As shown in fig. 2 and 3, the N first conductive modules 2 and the M second conductive modules 3 are inserted into the docking portion 11 of the housing 1 and arranged in a row along the arrangement direction L, and the plurality of guide posts 13 are divided into N + M groups in this embodiment to correspond to the first conductive module 2 and the second conductive module 3, respectively (as shown in fig. 2, two guide posts 13 disposed on the right side of the top edge of the docking portion 11 and two guide posts 13 disposed on the right side of the bottom edge of the docking portion 11 are a group and correspond to one first conductive module 2, and two guide posts 13 disposed on the left side of the top edge of the docking portion 11 and two guide posts 13 disposed on the left side of the bottom edge of the docking portion 11 are a group and correspond to the second conductive module 3). The first conductive module 2 includes a plurality of first transmission sheets 2a stacked along the arrangement direction L, and the outlines of the plurality of first transmission sheets 2a are substantially aligned with each other along the arrangement direction L.

In addition, the names of the elements "first" and "second" in the present embodiment are for convenience of description, and are not limited in order or structure. For example, the "first" transmission piece 2a may also be named as a transmission piece, and the transmission piece of the present embodiment may also be used alone (e.g., sold) or in other connectors, and the invention is not limited thereto.

Accordingly, the electrical connector 100 of the present embodiment preferably has no shielding member (e.g., the first shielding member 23 and the second shielding member 33 are not disposed) on the two outer end surfaces of the N first conductive modules 2 and the M second conductive modules 3 away from each other in the arrangement direction L, but the invention is not limited thereto.
As shown in fig. 4A to fig. 6, since the plurality of first transmission plates 2a of the present embodiment have the same structure, for the convenience of understanding, only the structure of a single first transmission plate 2a will be described below, but the present invention is not limited thereto. For example, in other embodiments not shown in the present disclosure, a part of the N first conductive modules 2a may include a first shielding element 23, and the other part of the first conductive modules 2a is not provided with the first shielding element 23.
The first transmission plate 2a includes a first insulating frame 21, a plurality of first signal terminals 22 fixed to the first insulating frame 21, and the first shield 23 mounted to the first insulating frame 21. In the present embodiment, the plurality of first signal terminals 22 are a plurality of pairs of differential signal terminals and are fixed to the first insulating frame 21 by insert injection molding, and the first shielding member 23 is mounted to the first insulating frame 21 by snap-fitting, but the present invention is not limited thereto.
The first insulating frame 21 is a sheet-shaped structure substantially perpendicular to the arrangement direction L, and the first insulating frame 21 includes a first front end 211 and a first rear end 212 that are elongated and located on opposite sides (e.g., left and right sides in fig. 4A), and a first bottom end 213 and a first top end 214 that are elongated and located on opposite sides (e.g., upper and lower sides in fig. 4A). The length direction of the first front end portion 211 is substantially perpendicular to the length direction of the first bottom end portion 213, the length direction of the first rear end portion 212 is substantially perpendicular to the length direction of the first top end portion 214, and the length direction of the first front end portion 211 is substantially parallel to the length direction of the first rear end portion 212, but the invention is not limited thereto.
Further, the first rear end 212 has a first groove 2121 formed therein for receiving the partial cross beam 4. The first bottom end 213 is formed with a plurality of limiting structures 2131, and each limiting structure 2131 of the present embodiment is a limiting channel 2131 substantially parallel to the arrangement direction L. The width of the upper half part of each limiting channel 2131 is larger than that of the lower half part. Furthermore, the first top end portion 214 is formed with a first engaging column 2141 for being inserted into one of the engaging grooves 121 of the housing 1.
Each of the first signal terminals 22 includes a first middle section 221, a first contact section 222 extending from one end of the first middle section 221 (e.g., the right end of the first middle section 221 in fig. 5), and a first mounting section 223 extending from the other end of the first middle section 221 (e.g., the lower end of the first middle section 221 in fig. 5). The first intermediate sections 221 of the first signal terminals 22 are fixed in the first insulating frame 21, the first contact sections 222 extend out of the first front end 211 and are arranged in a row along the height direction H, and the first mounting sections 223 extend out of the first bottom end 213 and are arranged in a row along the width direction W.
Furthermore, a part of each of the first middle sections 221 is exposed outside the first insulating frame 21, and the width of each of the first middle sections 221 is greater than that of the first middle section 221 embedded in the first insulating frame 21, but the invention is not limited thereto. For example, in other embodiments not shown in the present invention, the first middle section 221 may be completely embedded in the first insulating frame 21, and the width of each portion is the same.
The first shielding element 23 includes a first sheet 231 substantially perpendicular to the arrangement direction L, a plurality of first contact portions 232 extending from (a front edge of) the first sheet 231, a plurality of first mounting portions 233 and an offset mounting portion 234 extending from (a bottom edge of) the first sheet 231, and a first abutting portion 235 extending from (a top edge of) the first sheet 231. The first sheet 231 is fixed outside the first insulating frame 21, the first contact portions 232 extend out of the first front end portion 211 and are arranged in a row along the height direction H, and a part of each first mounting portion 233 and the offset mounting portion 234 extend out of the first bottom end portion 213.

The first mounting portions 233 are respectively limited by the limiting structures 2131 of the first insulating frame 21. Accordingly, each first mounting portion 233 of the first shielding element 23 can be limited by the limiting structure 2131, so as to obtain a supporting force, and the first mounting portion 233 is not easily deformed by an external force.
Further, each first mounting portion 233 includes a planar section 2331 bent substantially perpendicular to a first rotation direction from the first sheet 231 and an inserting section 2332 bent substantially perpendicular to a second rotation direction from the planar section 2331, and the first rotation direction (e.g., counterclockwise with the width direction W as the rotation axis in fig. 5) is opposite to the second rotation direction (e.g., clockwise with the width direction W as the rotation axis in fig. 5). In each limiting structure 2131 and the first mounting portion 233 limited by the limiting structure, the planar segment 2331 is fixed in the limiting channel 2131 (for example, the planar segment 2331 is embedded in the upper half of the limiting channel 2131), and the plug-in segment 2332 extends out of the limiting channel 2131.
As shown in fig. 7 to 9, since the plurality of second transmission pieces 3a of the present embodiment have substantially the same structure (only the outermost second transmission piece 3a does not include the second shielding member 33 and thus is different from the other second transmission pieces 3a), for the convenience of understanding, only the structure of a single second transmission piece 3a including the second shielding member 33 will be described below, but the present invention is not limited thereto. For example, in other embodiments not shown in the present disclosure, each of the M second conductive modules 3a may include a second shielding element 33.

The second insulating frame 31 is a sheet-shaped structure substantially perpendicular to the arrangement direction L, and the second insulating frame 31 includes a second front end 311 and a second rear end 312 that are elongated and located at opposite sides (e.g., left and right sides in fig. 7), and a second bottom end 313 and a second top end 314 that are elongated and located at opposite sides (e.g., upper and lower sides in fig. 7). The length direction of the second front end 311 is substantially perpendicular to the length direction of the second bottom end 313, the length direction of the second rear end 312 is substantially perpendicular to the length direction of the second top end 314, and the length direction of the second front end 311 is substantially parallel to the length direction of the second rear end 312, but the invention is not limited thereto.
Further, the second rear end 312 is formed with a second groove 3121 for receiving the partial cross beam 4. The second top end 314 is formed with a second engagement post 3141 for being inserted into one of the engagement grooves 121 of the housing 1.
Each second signal terminal 32 includes a second middle section 321, a second contact section 322 extending from one end of the second middle section 321 (e.g., the right end of the second middle section 321 in fig. 8), and a second mounting section 323 extending from the other end of the second middle section 321 (e.g., the lower end of the second middle section 321 in fig. 8). The second intermediate sections 321 of the second signal terminals 32 are fixed in the first insulating frame 21, the second contact sections 322 extend out of the second front end 311 and are arranged in a row along the height direction H, and the second mounting sections 323 extend out of the second bottom end 313 and are arranged in a row along the width direction W.
Further, each of the second middle segments 321 is completely embedded in the second insulating frame 31, and the widths of the portions are the same, but the invention is not limited thereto. For example, in other embodiments not shown in the present invention, the second middle section 321 may be partially exposed outside the second insulating frame 31, and the width of the second middle section 321 is larger than the second middle section 321 embedded in the second insulating frame 31.

The second mounting portions 333 and the second mounting sections 323 are aligned in a row in the width direction W. In more detail, each second mounting portion 333 is formed by bending the second plate 331 substantially perpendicularly along a third rotation direction (e.g., clockwise with respect to the height direction H in fig. 8), such that the wide surface of the second mounting portion 333 is not located on the same plane as the wide surface of the second mounting section 323.
