In the embodiment illustrated in the invention, the octagonal cavity 220 is a regular octagonal cavity.

[0058] Please combine Figure 6As shown in the illustrated embodiment of the present invention, the first mounting pin 22a3, the second mounting pin 22a4, the third mounting pin 22b3, and the fourth mounting pin 22b4 are each provided with a fisheye hole, so that the first mounting pin 22a3, the second mounting pin 22a4, the third mounting pin 22b3, and the fourth mounting pin 22b4 all have a certain degree of elasticity. The first mounting pin 22a3, the second mounting pin 22a4, the third mounting pin 22b3, and the fourth mounting pin 22b4 are respectively used to press into the first mounting hole 3051, the second mounting hole 3052, the third mounting hole 3053, and the fourth mounting hole 3054 to achieve electrical connection with the circuit board 300. The first mounting pin 22a3, the second mounting pin 22a4, the third mounting pin 22b3, and the fourth mounting pin 22b4 are located on both sides of the first elastic abutment pin 2114 of the first conductive terminal 211 and the second elastic abutment pin 2124 of the second conductive terminal 212. When the first elastic abutment pin 2114 and the second elastic abutment pin 2124 elastically abut against the circuit board 300, the reliability of the contact between the first elastic abutment pin 2114 and the second elastic abutment pin 2124 and the circuit board 300 can be guaranteed.

[0059] The first extension portion 22a2 is provided with a first retaining hole 22a21 penetrating the first extension portion 22a2 along the second direction A2-A2. The second extension portion 22b2 is provided with a second retaining hole 22b21 penetrating the second extension portion 22b2 along the second direction A2-A2. Furthermore, the cylindrical portion 22d is also provided with a first mounting notch 22d1 and a second mounting notch 22d2, both of which penetrate the cylindrical portion 22d along the first direction A1-A1. In the embodiment illustrated in the present invention, both the first mounting notch 22d1 and the second mounting notch 22d2 are formed jointly by the first shielding shell 22a and the second shielding shell 22b.

[0060] In one embodiment of the present invention, the conductive element 23 is a metal block or an electroplated plastic block.

The conductive element 23 includes a head 231, an insertion portion 232 connected to the head 231, and a first insertion hole 233 and a second insertion hole 234 penetrating the head 231 and the insertion portion 232 along the first direction A1-A1. The insertion portion 232 is provided with a first mounting protrusion 2321 and a second mounting protrusion 2322 on both sides. The insertion portion 232 is at least partially inserted into the cavity 220, and the first mounting protrusion 2321 and the second mounting protrusion 2322 are respectively inserted into the first mounting notch 22d1 and the second mounting notch 22d2 to achieve positioning and limiting. Furthermore, the insertion portion 232 is also provided with a first latching protrusion 2323 and a second latching protrusion 2324, which are respectively fixed in the first retaining hole 22a21 and the second retaining hole 22b21. The head 231 protrudes from the shielding sleeve 22. The first insertion hole 233 communicates with the first accommodating space 2112b for the insertion of the first mating conductive terminal of the mating connector. The second insertion hole 234 communicates with the second accommodating space 2122b for the insertion of the second mating conductive terminal of the mating connector. In the embodiment illustrated in the present invention, the head 231 is octagonal and matches the shape of the shielding sleeve 22. The cross-sectional area of ​​the first insertion hole 233 and the cross-sectional area of ​​the second insertion hole 234 are both smaller than the cross-sectional area of ​​the cavity 220 of the cylindrical portion 622d.

[0061] In the embodiment illustrated in the present invention, both the first conductive terminal 211 and the second conductive terminal 212 are made of a relatively thin metal material to facilitate impedance adjustment.

[0062] When the electrical connector 100 mates with the mating connector, the first mating conductive terminal and the second mating conductive terminal of the mating connector pass through the first insertion hole 233 and the second insertion hole 234 respectively, so as to be inserted into the first accommodating space 2112b of the first conductive terminal 211 and the second accommodating space 621b22 of the second conductive terminal 212 respectively.

[0063] When the first connector 100 and the mating connector have just separated (de-mating), the first mating conductive terminal and the second mating conductive terminal will at least partially enter the conductive element 23. At this time, a first air gap is formed radially between the conductive element 23 and the first mating conductive terminal, and a first air gap is also formed radially between the conductive element 23 and the second mating conductive terminal. In other words, at this time, both the first and second mating conductive terminals are circumferentially surrounded by corresponding first air gaps. The first air gaps and the conductive element 23 form an impedance medium located on the outer periphery. Since the impedance of air is very high, the conductive element 23 is needed to prevent impedance abrupt changes in the first and second mating conductive terminals.
