[0056] In summary, the electrical connector 100 of the present invention has the following beneficial effects:

[0057] (1) Each signal block 14S is located in a corresponding signal receiving groove 13S. The signal block 14S abuts against the rear side of the signal main body 21S. The signal block 14S increases the dielectric constant near the signal main body 21S, thereby increasing the capacitance near the signal main body 21S, so that the impedance of the signal main body 21S is relatively small. The signal block 14S extends upward into between the two signal branches 221S, increases the dielectric constant near the two signal branches 221S, thereby increasing the capacitance near the two signal branches 221S, and reduces the impedance of the two signal branches 221S, so that the impedance of the signal main body 21S and the signal branch 221S are matched. Compared with the case where the signal block 14S does not extend forward into between the two signal branches 221S, the signal block 14S extends forward into between the two signal branches 221S, which can increase the capacitance near the two signal branches 221S more, reduce the impedance of the two signal upper branches more, and make the signal end The impedance of the sub-2S is more matched; each grounding block 14G is correspondingly located in a grounding receiving groove 13G, and the grounding block 14G is against the rear side of the grounding main body 21G. In the left and right directions, since the grounding terminal 2G is located between two adjacent signal terminals 2S, the grounding block 14G is also located between the two signal terminals 2S. Under the premise that the signal terminal 2S and the grounding terminal 2G have the same contour and the signal receiving groove 13S and the grounding receiving groove 13G have the same structure, the volume of the grounding block 14G is smaller than the volume of the signal block 14S, so that the dielectric constant near the grounding terminal 2G is smaller, and the capacitance is proportional to the size of the dielectric constant. Therefore, the capacitance between the two adjacent signal terminals 2S located on both sides of the grounding terminal 2G is reduced, that is, the mutual capacitance between the two adjacent signal terminals 2S is reduced, and the crosstalk of the electrical connector 100 is proportional to the size of the mutual capacitance between the two adjacent signal terminals 2S. Therefore, the crosstalk of the electrical connector 100 is reduced, thereby improving SI performance.

[0058] (2) The signal support block 16S extends forward into between the two signal branches 221S, increasing the capacitance near the two signal branches 221S, reducing the impedance of the two signal branches 221S, thereby matching the impedance of the signal terminal 2S. Compared with the case where the signal support block 16S does not extend forward into between the two signal branches 221S, the signal support block 16S extends forward into between the two signal branches 221S, which can increase the capacitance near the two signal branches 221S more, reducing the impedance of the two signal branches more, thereby matching the impedance of the signal terminal 2S more. Since the ground terminal 2G is located between two adjacent signal terminals 2S, the ground support block 16G is also Located between the two signal terminals 2S, under the premise that the signal terminal 2S and the ground terminal 2G have the same profile and the signal receiving groove 13S and the ground receiving groove 13G have the same structure, the volume of the ground support block 16G is smaller than the volume of the signal support block 16S, so that the dielectric constant near the ground terminal 2G is smaller, and the capacitance is proportional to the size of the dielectric constant. Therefore, the capacitance between the two adjacent signal terminals 2S located on both sides of the ground terminal 2G is reduced, that is, the mutual capacitance between the two adjacent signal terminals 2S is reduced, and the crosstalk of the electrical connector 100 is proportional to the size of the mutual capacitance between the two adjacent signal terminals 2S. Therefore, the crosstalk of the electrical connector 100 is reduced, thereby improving the SI performance.

[0059] (3) On the premise that the signal terminal 2S and the ground terminal 2G have the same profile and the signal receiving groove 13S and the ground receiving groove 13G have the same structure, each signal receiving groove 13S is provided with two protrusions 15S, and each ground receiving groove 13G is provided with two recesses 15G. When the first docking element 200 presses the signal elastic portion 22S downward to the final position, when viewed from top to bottom, the protrusion 15S and the signal elastic portion 22S partially overlap, thereby increasing the capacitance near the signal terminal 2S and reducing the impedance of the signal terminal 2S, thereby matching the impedance of the signal terminal 2S; in the left and right directions, the two recessed portions 15G are respectively located on the left and right sides of the ground terminal 2G, which can reduce the dielectric constant near the ground terminal 2G, and the capacitance is proportional to the size of the dielectric constant, so that the capacitance between the two adjacent signal terminals 2S located on both sides of the ground terminal 2G is reduced, that is, the mutual capacitance between the two adjacent signal terminals 2S is reduced, and the crosstalk of the electrical connector 100 is proportional to the size of the mutual capacitance between the two adjacent signal terminals 2S, so the crosstalk of the electrical connector 100 is reduced, thereby improving the SI performance.

[0060] The above detailed description is only an explanation of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this creation are included in the patent scope of this creation.
