The insulating body1includes a plurality of limiting blocks adjacent to the mating surface10and a plurality of terminal limiting slots of which each is located between two adjacent limiting blocks. The insulating body1further includes a plurality of relief slots adjacent to the mating surface10. The relief slots are in communication with corresponding terminal limiting slots in the first direction D1-D1. In the illustrated embodiment of the present disclosure, both a bottom of the top wall11and a top of the bottom wall12are provided with the plurality of limiting blocks.

Referring toFIGS.5,7and9, the plurality of terminal modules include a first terminal module21, a second terminal module22, a third terminal module23and a fourth terminal module24. The first terminal module21and the second terminal module22are arranged opposite to each other along a vertical direction. The third terminal module23and the fourth terminal module24are arranged opposite to each other along the vertical direction. The structures of the first terminal module21, the second terminal module22, the third terminal module23, and the fourth terminal module24are similar.

The first terminal module21includes a plurality of first conductive terminals211, a first fixing block212for fixing the first conductive terminals211, and a first ground connection piece213. In the illustrated embodiment of the present disclosure, the plurality of first conductive terminals211are insert-molded in the first fixing block212, so that the first terminal module21is formed as a whole, thereby facilitating assembly. As shown inFIGS.10and11, the plurality of first conductive terminals211include a plurality of differential signal terminal pairs DP, a plurality of first ground terminals G1 and a plurality of second ground terminals G2. Each differential signal terminal pair DP includes a first signal terminal S1 and a second signal terminal S2 which are disposed adjacent to each other.

The first ground connection piece213connects the first ground terminals G1 and the second ground terminals G2 so as to increase the grounding area and improve the grounding effect. In the illustrated embodiment of the present disclosure, a width of any one of the first ground terminals G1 and the second ground terminals G2 is larger than that of the first signal terminal S1 and the second signal terminal S2, thereby improving the shielding effect.

Each first conductive terminal211includes a first elastic mating portion2111protruding into the mating slot101, a first end portion2112extending from the first elastic mating portion2111, and a first mounting portion2113for being mounted to the circuit board.

The second relief slots127and corresponding second terminal limiting slots125are in communication with each other in the first direction D1-D1. The relief slots (for example, the first relief slot126and the second relief slot127) have a function of adjusting impedance of the electrical connector100. If the relief slot is not provided, the impedance of the electrical connector100is low. After the relief slot is set, the impedance of the electrical connector100is relatively high, which can improve the insertion loss resonance at the same time.

The limiting protrusions include a first protrusion1211provided on the first limiting block121, a second protrusion1221and a fourth protrusion1222provided on the second limiting block122, and a third protrusion1231provided on the third limiting block123.

The second protrusion1221protrudes toward the first protrusion1211in the second direction D2-D2. The third protrusion1231protrudes toward the fourth protrusion1222in the second direction D2-D2. The fourth protrusion1222protrudes toward the third protrusion1231in the second direction D2-D2. In other words, the first protrusion1211and the second protrusion1221protrude toward each other in the second direction D2-D2. The third protrusion1231and the fourth protrusion1222protrude toward each other in the second direction D2-D2. The first end portion2112of the first signal terminal S1 is restricted between the first protrusion1211and the second protrusion1221so as to prevent the first end portion2112of the first signal terminal S1 from being deviated from side to side. In other words, opposite lateral sides of the first end portion2112of the first signal terminal S1 are restricted by the first protrusion1211and the second protrusion1221, respectively. A gap between the first protrusion1211and the first end portion2112of the first signal terminal S1 along the second direction D2-D2 is X1, where 0.04 mm≤X1≤0.1 mm. A gap between the second protrusion1221and the first end portion2112of the first signal terminal S1 along the second direction D2-D2 is X2, where 0.04 mm≤X2≤0.1 mm. This arrangement is beneficial to improve the alignment of the first signal terminal S1. In an embodiment of the present disclosure, X1=0.05 mm, and X2=0.05 mm. The first end portion2112of the second signal terminal S2 is restricted between the third protrusion1231and the fourth protrusion1222so as to prevent the first end portion2112of the second signal terminal S2 from being deviated from side to side.

A gap between the fourth protrusion1222and the first end portion2112of the second signal terminal S2 along the second direction D2-D2 is X4, where 0.04 mm≤X4≤0.1 mm. This arrangement is beneficial to improve the alignment of the second signal terminal S2. In an embodiment of the present disclosure, X3=0.05 mm, and X4=0.05 mm.

Referring toFIG.11, in an embodiment of the present disclosure, the first side surface121aand the second side surface122aare parallel to each other.

A distance between the third side surface123aand the fourth side surface122bis greater than a width of the first end portion2112of the second signal terminal S2. In the illustrated embodiment of the present disclosure, the opposite lateral sides of the first end portion2112of the first signal terminal S1 are separated from the first side surface121aand the second side surface122aby a certain distance, respectively. The opposite lateral sides of the first end portion2112of the second signal terminal S2 are separated from the third side surface123aand the fourth side surface122bby a certain distance, respectively. With this arrangement, when the first signal terminal S1 needs to be deformed, the first end portion2112of the first signal terminal S1 can move unimpeded in the first relief slot126. When the second signal terminal S2 needs to be deformed, the first end portion2112of the second signal terminal S2 can move unimpeded in the second relief slot127. With this design of the present disclosure, since protruding areas of the first protrusion1211and the second protrusion1221, as well as protruding areas of the third protrusion1231and the fourth protrusion1222are relatively small, the risk of scratches of the first signal terminal S1 and the second signal terminal S2 when moving with respect to the insulating body1is reduced, and the reliability of the electrical connector100is improved. By providing the first relief slot126and the second relief slot127, the risk of scratches of the first signal terminal S1 and the second signal terminal S2 when moving with respect to the insulating body1is further reduced. At the same time, the first relief slot126and the second relief slot127can also have a positive impact on maintaining signal integrity when the first signal terminal S1 and the second signal terminal S2 are transmitting signals.

Besides, the farther away from the first end surface2112aof the first signal terminal S1 in the first direction D1-D1, the greater the distance. The minimum distance between the third side surface123aand the fourth side surface122bis greater than the width of the first end portion2112of the second signal terminal S2. Besides, the farther away from the first end surface2112aof the second signal terminal S2 in the first direction D1-D1, the greater the distance. In the illustrated embodiment of the present disclosure, opposite lateral sides of the first end portion2112of the first signal terminal S1 are separated from the first side surface121aand the second side surface122aby a certain distance, respectively. Opposite lateral sides of the first end portion2112of the second signal terminal S2 are separated from the third side surface123aand the fourth side surface122bby a certain distance, respectively.
