In the embodiment illustrated in this utility model, the docking module 300 is a docking circuit board, which includes a plurality of docking conductive sheets 301 located on its upper and lower surfaces.

[0051] Please refer to Figure 2 and Figure 5 As shown, the electrical connector 100 includes an insulating body 1 and a terminal module disposed within the insulating body 1. The insulating body 1 has a storage space 10 and a mating interface 10a. The terminal module is at least partially disposed in the storage space 10, and the mating interface 10a is used for insertion of the mating module 300.

[0052] In some implementation methods, please refer to Figure 2 and Figure 3As shown, the terminal module includes a first terminal module 2, a second terminal module 3, a third terminal module 4, and a fourth terminal module 5.

The first terminals 21 have a bent structure. The first plastic parts 22 are disposed at the bends of the first terminals 21, thereby reducing the impedance at the bends of the first terminals 21. The first terminals 21 are fixed to the first insulating blocks 25 and the second insulating blocks 26. Please refer to... Figure 15 As shown, the first insulating block 25 has a first opening 250, and the first grounding plate 23 is disposed within the first opening 250. The second insulating block 26 has a second opening 260, and the second grounding plate 24 is disposed within the second opening 260.

The first body 211 has a bent structure, and the first plastic part 22 is disposed at the bend of the first body 211. Since the dielectric constant of air is less than that of plastic, the placement of the first plastic part 22 at the bend of the first body 211 can increase the dielectric constant at the bend, thereby reducing the impedance at the bend of the first body 211 and helping to reduce current loss. Accordingly, in the design process, the width of the bend of the first body 211 can be appropriately reduced to increase the spacing between the bends of adjacent first terminals 21, reducing crosstalk. The first elastic arm 212 is configured to be in contact with the docking conductive sheet 301 on the upper surface of the docking module 300. The first tail 213 is configured to be connected to the welding sheet 202 of the first row L1.

The first signal terminal S1 and the second signal terminal S2 form a differential pair signal terminal, which is located between the first ground terminal G1 and the second ground terminal G2. Since the first plastic part 22 is provided at the bend of the first body 211, the width of the first bend portion 2113 of the first signal terminal S1 and the first bend portion 2113 of the second signal terminal S2 can be appropriately reduced during the design process, thereby increasing the distance between the first bend portion 2113 of the first signal terminal S1 and the first bend portion 2113 of the second signal terminal S2 and reducing crosstalk between the first signal terminal S1 and the second signal terminal S2.

[0058] In some implementation methods, please refer to Figure 8 and Figure 9 As shown, one end of the first plastic part 22 is connected to the first grounding plate 23, and the other end of the first plastic part 22 is connected to the second grounding plate 24, thereby stabilizing the first plastic part 22 at the bend of the first body 211.

[0061] Please refer to Figure 21 and Figure 22 As shown, the first plastic part 22 includes a first surface 221, a second surface 222 connected to one end of the first surface 221, a first side surface 223 connected to the other end of the first surface 221, a second side surface 224 connected to the other end of the second surface 222, and a third surface 225 connecting the first side surface 223 and the second side surface 224.

The third surface 225 is an arc-shaped surface, and the surface of the first bent portion 2113 opposite to the third surface 225 is also an arc-shaped surface.

[0062] Please refer to Figure 14 and Figure 22 As shown, the first plastic part 22 is provided with a first protrusion 2251 extending outward from the third surface 225, and the first protrusion 2251 abuts against the first bending portion 2113. The first bending portion 2113 supports the first plastic part 22, thereby improving the assembly stability of the first plastic part 22.

[0063] In some implementation methods, please refer to Figure 13 and Figure 14 As shown, the first plastic part 22 is provided with a plurality of first protrusions 2251, and the first bent portion 2113 of the first grounding terminal G1 and the first bent portion 2113 of the second grounding terminal G2 abut against the corresponding first protrusions 2251. A first gap 2200 exists between the first plastic part 22 and the first bent portion 2113 of the first signal terminal S1 and the first bent portion 2113 of the second signal terminal S2. The size of the first gap 2200 can be adjusted according to actual needs. The smaller the value of the first gap 2200, the smaller the width of the first bent portion 2113 can be set. Of course, when designing the width of the first bent portion 2113, its structural stability and structural strength must also be comprehensively considered.
