[0033] like Figure 1 As shown, the electrical connector 100 of the present invention includes an insulating body 1, which houses multiple terminals and a grounding member 4. The multiple terminals are blanked and formed, and are arranged side by side in a horizontal direction. The multiple terminals include multiple differential signal terminal pairs S and multiple grounding terminals 3, with the differential signal terminal pairs S located between adjacent grounding terminals 3 in the horizontal direction.

[0034] like Figure 1 and Figure 6As shown, a plurality of first receiving grooves 10 and a plurality of second receiving grooves 11 are formed by recessing forward from the rear surface of the insulating body 1. The plurality of first receiving grooves 10 and the plurality of second receiving grooves 11 are arranged side by side in the left-right direction, and the plurality of first receiving grooves 10 respectively accommodate a plurality of differential signal terminal pairs S, and the plurality of second receiving grooves 11 respectively accommodate a plurality of grounding terminals 3. A partition wall 14, a first partition 15 and a second partition 16 are provided between two adjacent first receiving grooves 10 on the left and right sides. An extension portion 141 is formed by protruding from the left and right side surfaces of the partition wall 14, and a protrusion portion 151 is formed by protruding from the left and right side surfaces of the first partition 15. In other embodiments, the extension portion 141 may also be formed by protruding only from the left side surface or the right side surface of the partition wall 14, that is, the partition wall 14 may also be provided with only one extension portion 141; similarly, the first partition 15 may also be provided with only one protrusion portion 151. Multiple first grooves 12 and multiple second grooves 13 are formed recessed forward from the rear surface of the insulating body 1, and are arranged side by side in the left-right direction. In the vertical direction, the first groove 12 is located between the first barrier 15 and the second barrier 16; in the left-right direction, the first groove 12 is located between two adjacent first receiving grooves 10, and the first groove 12 connects to the two first receiving grooves 10 on its left and right sides; in the left-right direction, the second groove 13 is located between adjacent first receiving grooves 10 and second receiving grooves 11, and the second groove 13 connects to the first receiving grooves 10 and second receiving grooves 11 on its left and right sides. The insulating body 1 also includes multiple third grooves 17 recessed forward from the rear surface of the second barrier 16, and the third grooves 17 connect to the two first receiving grooves 10 on its left and right sides.

[0035] like Figure 4 and Figure 10 As shown, each differential signal terminal pair S includes two signal terminals 2. Each signal terminal 2 has a connecting portion 20, a mating portion 21 extending forward from the connecting portion 20, and a conductive portion 22 extending outward from the connecting portion 20 and out of the insulating body 1. Each connecting portion 20 has a first surface 201 and a second surface 202 disposed opposite each other in the left-right direction. Both the first surface 201 and the second surface 202 are planar. Each connecting portion 20 also has a first portion 203 adjacent to the mating portion 21 and a second portion 204 adjacent to the conductive portion 22. The first portion 203 has a first end 203a and a second end 203b. Specifically, the mating portion 21 extends forward from the first end 203a.

[0036] like Figure 5 、 Figures 8 to 10As shown, before the signal terminal 2 is installed in the first receiving groove 10, in the same differential signal terminal pair S, there is a fourth distance D4 between two adjacent second portions 204 along the left and right directions, the distance between two adjacent docking portions 21 is equal to the fourth distance D4, and the distance between two adjacent conductive portions 22 is also equal to the fourth distance D4. After the signal terminal 2 is installed in the first receiving groove 10, in the same differential signal terminal pair S, first, the partition wall 14 separates two adjacent docking portions 21, and the docking portion 21 and the extension portion 141 abut against each other in the left-right direction, so that a third distance D3 is provided between the two adjacent docking portions 21 in the left-right direction, and the third distance D3 is greater than the fourth distance D4; second, the second barrier 16 separates two adjacent first portions 203, and the third groove 17 and the first end 203a are arranged side by side in the left-right direction, so that the side of the first end 203a adjacent to the second barrier 16 in the left-right direction is exposed to the air, and a first distance D1 is provided between the two adjacent first ends 203a in the left-right direction, and the first distance D1 is less than the third distance D3; at the same time, along the left In the right direction, a fifth distance D5 is defined between the side of the first end 203a distal from the second barrier 16 and the inner wall of the first receiving groove 10. A distance W is defined between the side of the second end 203b distal from the second barrier 16 and the inner wall of the first receiving groove 10. This distance W is smaller than the fifth distance D5, allowing the side of the first end 203a distal from the second barrier 16 in the left-right direction to be exposed to the air. The first barrier 15 separates two adjacent second portions 204, and the protrusion 151 is positioned between and supports the two adjacent second portions 204, resulting in a second distance D2 between the two adjacent second portions 204. The second distance D2 is greater than the fourth distance D4, which is also greater than the first distance D1. Furthermore, in the vertical direction, the first groove 12 is closer to the docking portion 21 than the guide portion 22.

[0037] like Figure 2 and Figure 3 As shown, each ground terminal 3 has a fixed portion 30 received in the second receiving slot 11. A latching arm 31 extends rearward from the fixed portion 30 out of the insulating body 1. The latching arm 31 is closer to the conductive portion 22 than to the mating portion 21 in the vertical direction. A gap P is defined between the latching arm 31 and the fixed portion 30 in the front-to-back direction. The latching arm 31 extends from one side of the fixed portion 30 in the front-to-back direction to form a latching portion 311.

[0038] The grounding member 4 comprises a main body 40, a plurality of slits 41 extending through the main body 40 in the front-to-back direction, and a plurality of recessed holes 42 extending forward from the rear surface of the main body 40. The slits 41 correspond to the engaging arms 31 and extend downward through the main body 40, respectively. The recessed holes 42 are located above the slits 41. During installation of the grounding member 4 on the insulating body 1, the main body 40 is inserted into the gap P from top to bottom, the engaging arms 31 are inserted into the slits 41 from bottom to top and pass through the slits 41 in the front-to-back direction, and the latch portions 311 are inserted into the recessed holes 42 in the front-to-back direction and contact the inner walls of the recessed holes 42.

[0039] In summary, the electrical connector 100 of the present invention has the following beneficial effects:

[0040] (1) In the same differential signal terminal pair S, a first distance D1 is provided between two adjacent first ends 203a in the left-right direction, and a second distance D2 is provided between two adjacent second portions 204, wherein the second distance D2 is greater than the fourth distance D4, and the second distance D2 is also greater than the first distance D1. Under the premise of ensuring that the distance between the two conductive portions 22 of the same differential signal terminal pair S in the left-right direction is equal to the prescribed distance between the two adjacent docking portions 21 in the docking element, thereby not affecting the conductive connection between the conductive portions 22 and the docking element, the distance between the two first ends 203a in the same differential signal terminal pair S in the left-right direction is reduced. According to the tight coupling principle, the mutual inductance between the two signal terminals 2 in the same differential signal terminal pair S is increased, while the self-inductance remains unchanged, thereby reducing the inductance outside the same differential signal terminal pair S, improving the anti-interference capability of the differential signal terminal pair S, and improving the high-frequency performance of the electrical connector 100. At the same time, by setting the connecting part 20 to have a first plate surface 201 and a second plate surface 202 arranged opposite to each other in the left and right directions, the first plate surface 201 and the second plate surface 202 are both flat, so that the connecting part 20 can be directly formed by blanking without bending, thereby simplifying the process of the signal terminal 2.

[0041] (2) Since the first distance D1 is smaller than the second distance D2, according to the formula C = εS / d (C is the capacitance, ε is the dielectric constant of the transmission medium), as the distance d decreases, the capacitance C increases, and the formula It can be seen that the impedance Z of the first end 203a is reduced; by setting the third groove 17 to connect the two first receiving grooves 10 located on the left and right sides thereof, the third groove 17 and the first end 203a are arranged side by side in the left and right directions, and there is a fifth distance D5 between the side of the first end 203a away from the second partition 16 and the inner wall of the first receiving groove 10 in the left and right directions, and there is a spacing W between the side of the second end 203b away from the second partition 16 and the inner wall of the first receiving groove 10, and the spacing W is smaller than the fifth distance D5, so that the left and right sides of the first end 203a are exposed to the air, that is, the first receiving groove 10 where the first end 203a is located is filled with more air, the dielectric constant of air is smaller than the dielectric constant of plastic, the capacitance C is reduced, and the impedance Z is increased, thereby matching the impedance of the first end 203a and improving the high-frequency performance.

[0042] (3) In the same differential signal terminal pair S, by setting the extension portion 141 and the docking portion 21 to abut against each other in the left-right direction, a third distance D3 is provided between the two docking portions 21 of the two signal terminals 2 in the left-right direction, the third distance D3 is greater than the fourth distance D4, and the first distance D1 is less than the third distance D3, so that the distance between the two docking portions 21 in the same differential signal terminal pair S in the left-right direction is equal to the specified distance between the two adjacent corresponding parts in another docking element, thereby not affecting the electrical conduction between the docking portion 21 and the other docking element. According to the tight coupling principle, the mutual inductance between the two signal terminals 2 in the same differential signal terminal pair S is increased, the self-inductance remains unchanged, the inductance outside the same differential signal terminal pair S is reduced, the anti-interference ability of the differential signal terminal pair S is improved, and the high-frequency performance of the electrical connector 100 is improved.

[0043] (4) According to the formula C = εS / d (C is the capacitance, ε is the dielectric constant of the transmission medium) and the formula It can be seen that since the first distance D1 is smaller than the second distance D2, the distance d decreases and the capacitance C increases, resulting in a decrease in the impedance Z of the first part 203. By arranging multiple first grooves 12 and multiple second grooves 13 side by side in the left-right direction, the first groove 12 is closer to the docking part 21 than the guiding part 22 in the up-down direction. The first groove 12 is located between two adjacent first receiving grooves 10 in the left-right direction, and the first groove 12 connects the two first receiving grooves 10 on its left and right sides; the second groove 13 is located between the adjacent first receiving grooves 10 and the second receiving grooves 11 in the left-right direction, and the second groove 13 connects the first receiving grooves 10 and the second receiving grooves 11 on its left and right sides, that is, the first plate surface 201 and the second plate surface 202 corresponding to the first part 203 are partially exposed to the air. Since the dielectric constant of air is smaller than the dielectric constant of plastic, the capacitance C decreases, which increases the impedance Z of the first part 203, thereby matching the impedance of the first part 203.

[0044] (5) First, by setting the main body 40 to be installed into the gap P from top to bottom, and the clamping arm 31 to be installed into the slit 41 from bottom to top and pass through the slit 41 in the front-to-back direction, the main body 40 is limited between the clamping arm 31 and the fixing part 30 in the front-to-back direction, thereby limiting the displacement of the grounding member 4 in the front-to-back direction. At the same time, the assembly of the clamping arm 31 and the slit 41 further limits the displacement of the grounding member 4 in the left-to-right direction. Furthermore, by setting a plurality of recessed holes 42 respectively located above the plurality of slits 41, and the buckle part 311 is installed into the recessed holes 42 in the front-to-back direction and contacts the inner wall of the recessed holes 42, while limiting the displacement of the grounding member 4 in the up-down direction, the grounding return path is increased, making it difficult for the grounding member 4 to be displaced in the up-down, front-to-back and left-to-right directions, thereby improving the stability of the grounding member 4. Secondly, since the second distance D2 is greater than the first distance D1, the distance between the second portions 204 of the signal terminals 2 between two adjacent differential signal terminal pairs S is closer, resulting in greater crosstalk. By arranging the clamping arm 31 closer to the conductive portion 22 than the docking portion 21 along the up and down directions, the shielding area between the second portions 204 of the signal terminals 2 between two adjacent differential signal terminal pairs S is increased, thereby reducing crosstalk.
