The terminal 20 includes a first row of terminals 21 exposed on the first surface 121 of the docking tongue plate 12. The first row of terminals 21 includes a plurality of differential signal terminal pairs 20S and a plurality of grounding terminals 20G.

Each shielding part 31 is provided with an opening 33 and an insulating block 40 fixed in the opening 33. The insulating block 40 faces but does not abut against the contact part 20a of the differential signal terminal pair S, so as to achieve impedance adjustment.

[0022] As shown Figures 3 to 6 As shown, the first row of terminals 21 are fixed together by an insulating strip 50; the first grounding part 30 is assembled on one side of the first row of terminals 21, and its grounding part 32 is welded and fixed to the grounding terminal 20G, and then they are inserted into the insulating body 10 together. As shown Figure 6 As shown, the male connector 100 further includes a second grounding part 60, which is fixed to one side of the insulating strip 50 and extends out of the base part 11 of the insulating body 10. The second grounding part 60 includes a plurality of shielding parts 61 corresponding to the differential signal terminal pairs S one by one and a plurality of grounding parts 62 abutting against the grounding terminals G. The grounding parts 62 are welded and fixed to the grounding terminals 20G. The welding method of the grounding part 32 and the grounding part 62 can be laser welding. Therefore, the first row of terminals 21, the first grounding part 30, the second grounding part 60 and the insulating strip 50 form a terminal module 70 and are inserted into the insulating body 10 together. The first and second in the first and second grounding parts are only used to distinguish different grounding parts and there is no sequence. In some cases, only the first grounding part can be provided.

[0023] The base 11 of the insulating body 10 is provided with a receiving cavity 110 opening backward. The insulating strip 50 is inserted into the receiving cavity 110 and fixed to the receiving cavity 110 by a snap-fastening method. A plurality of snap protrusions 51 are provided on the surface of the insulating strip 50, and the base 11 is provided with a snap groove 111 communicating with the receiving cavity 110. The snap protrusions 51 are snapped into the snap groove 111, thereby fixing the terminal module 70 to the insulating body 10. The terminal 20 further includes a second row of terminals 22 exposed on the second surface 122 of the docking tongue plate 12. The second row of terminals 22 is inserted into the insulating body 10. The base 11 of the insulating body 10 is provided with a channel 112 for the first row of terminals 21 and the second row of terminals 22 to pass through. The channel 112 communicates with the first surface 121 and the second surface 122 of the docking tongue plate 12. The insulating body 10 includes an insulating base 13 and an insulating frame 14 assembled together. The insulating base 13 is provided with a base 11 and a docking tongue plate 12, and the insulating frame 14 is provided with a frame opening 141 for accommodating the base 11.

[0024] In the first grounding member 30 of this embodiment, refer Figure 2 As shown, at least a part of the first surface 121 of the docking tongue plate 12 is locally cut away between the differential signal terminal pairs S, so that except for the contact portion 20a of the insulating block 40 of the first grounding member 30 facing the differential signal terminal pairs S, other parts are exposed on the first surface 121.

[0025] Regarding the first grounding member 30, more specifically, refer Figures 7 to 9 As shown, the first grounding member 30 is provided with a shielding portion 31 and a plurality of grounding portions 32 abutting against the grounding terminal 20G. The adjacent shielding portions 31 are connected by a cross beam portion 34. The grounding portions 32 extend from the cross beam portion 34 and abut against the grounding terminal 20G. Each shielding portion 31 is provided with an opening 33 and an insulating block 40 fixed in the opening 33. The insulating block 40 is of an H-shaped structure, including a pair of insulating strips 41 facing the differential signal terminal pairs S and a cross strip 42 connecting the insulating strips 41. The pair of insulating strips 41 and the cross strip 42 are integrally injection-molded on the opening 33. Among them, the dielectric constant value of the insulating material of the insulating block 40 is lower than the dielectric constant value of the docking tongue plate 12, so as to achieve impedance adjustment.

[0026] Refer Figure 10 As shown, for the signal terminal 20S in another embodiment, the signal terminal 20S includes a contact portion 203. A thinned area 204 is provided on the surface of the contact portion 203 facing the docking tongue plate 12. The thinned area 204 does not penetrate the front end of the contact portion 203 to improve the impedance effect.

[0027] In summary, the above are only the preferred embodiments of the present invention, and the scope of the present invention should not be limited thereby. That is, all simple equivalent changes and modifications made according to the claims of the present invention and the content of the specification of the present invention should still fall within the scope covered by the patent of the present invention.
