It is very short to reduce the impedance. In addition, the distance between the two second soldering portions 381, 384 located at the outermost ends of the optical fiber 5' is also enlarged. The second soldering portion 385 of the grounding terminal 33 is located in the middle and the grounding terminal 33 is The distance between the second soldering portion 385 and the second soldering portion 382 of the adjacent third pair of differential signal terminals 31 and the second soldering portion 383 of the fourth pair of differential signal terminals 32 is relatively large, thereby facilitating the accommodation of the optical fiber 5. In the present embodiment, the distance between the first soldering portions 283 and 284 of the first pair of differential signal terminals 23 and 24 and the second soldering portions 381 and 382 of the second pair of differential signal terminals 3 are The distance between the distance and the second soldering portions 383 and 384 of the third pair of differential signal terminals 32 are the same 'to ensure that the impedance of each group of differential signals is substantially the same. In addition, the first soldering portions 283, 284 of the first pair of differential signal terminals 23, 24 are contracted and arranged at an intermediate position of the circuit board 6, and the first pair of differential signal terminals 23, 24 are seen from the mating connector insertion direction B_B. The first soldering portions 283 and 284 are located between the second soldering portions 381 and 382 of the second pair of differential signal terminals 31 and the second soldering portions 383 and 381 of the third pair of differential signal terminals 32, in order to reduce the differential signal terminals. Crosstalk between pairs. Referring to FIG. 6 , the first and first soldering portions 28 , 38 are arranged in three rows parallel to each other, wherein the second soldering portion 38 is located in the first row farthest from the mating surface 7 , and the first soldering The portion 283 is located in the second row closest to the mating surface 71, and the remaining first splicing portions 281, 282, 284 are arranged in the third row in the middle. In addition, the corresponding first and second soldering portions 28, 38 occupy the widest pitch of the circuit board 6 from the back to the Hu, that is, between the two second soldering portions 381, 384 at the most ends of the first row. The spacing between the two first soldering portions 281, 282 at the most ends of the third row is the same; likewise, since the second row has only one first soldering portion 283, the two ends of the third row are the first two The spacing between the welds 28 282 is also greater than the width of the first weld 283 itself in the second row. The second abutting portion 35 protrudes beyond the second insulative housing 8 and is received in the terminal receiving groove 111. Since the boss 112 is higher than the second abutting portion 35, the protruding boss 112 can prevent the metal casing of the mating electrical connector from hitting the second abutting portion 35, thereby functioning as an antistatic. The bottom surface of the second insulative housing 8 is provided with a plurality of spaced-apart recesses 81 for providing sufficient deformation space for the first mating portion 25 of the first conductive terminal 2''. The C-C1 direction, the C2_C2 direction, the C3_C3 direction, the A1_A1 direction, and the A2 a2 7 201037905 directions are all parallel to each other and are perpendicular to the insertion direction B B of the connector. In the present embodiment, the second soldering portion 385 of the ground terminal 33 is also opposite to the insertion direction BB of the mating connector. Of course, in other embodiments, the second welded portion may also not follow the B-B direction. In the present embodiment, the insulative housing 9 of the socket electrical connector 100 includes a first insulative housing 1 and a second insulative housing 8 that are mutually assembled. Therefore, the corresponding tongue=91 of the insulative housing 9 also includes two parts, that is, The protruding portion n and the second insulating body 8 protrude from the base portion, and the tongue and groove 91 extends into the insertion interface 7 for mating with the mating connector. The first abutting portion 25 of the first conductive terminal 20 and the second abutting portion of the second conductive terminal 3' are both located on the same side of the tongue 91 (in the present embodiment, the lower side of the tongue 91) In other embodiments, the insulative housing 9 may also be provided in one piece. At this time, the V electrical terminal 2 may be mounted on the insulative housing 9 by assembly, correspondingly at this time, the tongue The plate 91 is also a one-piece type, and the tongue plate 91 can be mounted on the insulative housing 9 by being integrally formed or assembled with the insulative housing 9.
