[0029] Embodiments of the connector of the present invention:

[0030] As shown in Figures 1, 2, 3, 4, and 9, the connector in this embodiment is a female connector 100, and the corresponding adapter connector is a male connector 200. The contact members of the male connector 200 are male pins 201, wherein the grounding contact members of the male connector 200 are male grounding pins, and the signal contact members of the male connector 200 are male signal pins. The female connector 100 includes a connector housing 1, a shielding member 3 disposed on the connector housing 1, and a plurality of terminal modules 2 mounted on the connector housing 1. The terminal modules 2 include an insulator and signal terminals 21 fixed to the insulator. The signal terminals 21 are arranged in pairs to form differential pairs. The signal terminals 21 have spring clip ends extending from the insulator, which constitute the mating ends. Shielding sheets 22 are provided on both sides of the insulator thickness direction of the terminal module 2.

[0031] The connector housing 1 comprises a U-shaped body, comprising a base plate 11 and two opposing side plates 12 disposed on either side of the base plate 11. Opposite sides of the two side plates 12 are provided with mounting slots for the corresponding insulators of the terminal module 2. Multiple rows of shielding cylinders 13 are arranged on the base plate 11 of the connector housing 1. Adjacent rows of shielding cylinders 13 are spaced in the direction b in Figure 3, which is the direction of the thickness of the insulators of the terminal module 2. Multiple shielding cylinders 13 are spaced apart within a row and are integrally formed with the U-shaped body of the connector housing 1. The two side plates 12 of the connector housing 1 are opposite to each other in the spacing direction of the shielding isolation tubes 13 in the same row, and the spacing direction of the shielding isolation tubes 13 in the same row is the direction a in Figure 3. Each terminal module 2 corresponds to a row of shielding isolation tubes 13, and each differential pair of the terminal module 2 corresponds to a shielding isolation tube 13. The plug-in ends of the two signal terminals 21 of the differential pair of the terminal module 2 extend into the same shielding isolation tube 13. A connecting wall is provided in the shielding isolation tube 13, and the plug-in ends of the two signal terminals 21 of the differential pair extend to both sides of the connecting wall respectively. The bottom plate 11 of the connector housing 1 is provided with signal through-holes corresponding to the inner cavity of the shielding isolation tube 13. Each shielding isolation tube 13 corresponds to two signal through-holes and the two signal through-holes are located on both sides of the connecting wall. When the male connector 200 and the female connector 100 are plugged in, the male signal pin passes through the signal through-hole on the bottom plate 11 to extend into the shielding isolation tube 13 and contact the plug-in end of the signal terminal 21. The shielding member 3 is disposed at the shielding isolation cylinder 13 and is used to surround and shield the plug-in ends of the signal terminals 21 in the shielding isolation cylinder 13 .

[0032] As shown in Figures 3, 4 and 5, the same row of shielding isolation tubes 13 corresponds to a shielding component 3. The shielding component 3 includes a first side plate 31 and a second side plate 32 arranged opposite to each other and a plurality of connecting tubes 33 arranged between the first side plate 31 and the second side plate 32. The first side plate 31 and the second side plate 32 constitute two shielding side walls, and the connecting tubes 33 constitute a shielding connector. Any two adjacent connecting tubes 33 and the first side plate 31 and the second side plate 32 form a shielding cavity. After the shielding component 3 is installed on the connector housing 1, each shielding isolation tube 13 is respectively located in the corresponding shielding cavity. The shielding isolation tubes 13 in the same row are respectively located in each shielding cavity of the same shielding component 3. By forming the shielding cavity, the first side plate 31, the second side plate 32 and the two adjacent connecting tubes 33 surround and shield the plug-in end of the signal terminal 21 in the shielding isolation tube 13.

[0033] As shown in Figures 3, 5, 6 and 7, the first side plate 31 and the second side plate 32 are both flat plates. The first side plate 31 and the second side plate 32 are opposite to each other in the direction b in Figure 3. The connecting tube 33 is generally a rectangular tube. The connecting tubes 33 of the same shielding member 3 are spaced apart in the direction a in Figure 3. The connecting tube 33 passes through in the direction c in Figure 3. The connecting tube 33 is formed by bending the plate. The opposite side walls of the connecting tube 33 are respectively attached to the first side plate 31 and the second side plate 32 and welded to fix. The other opposite side walls are perpendicular to the side plates and constitute separating side walls. The sidewalls of the connecting tube 33 that are fixed to the side panels constitute fixed sidewalls. The two fixed sidewalls oppose each other in the direction b in Figure 3 , while the two separating sidewalls oppose each other in the direction a in Figure 3 . A first spring claw 331 is provided on the fixed sidewall fixed to the first side panel 31, and a second spring claw 332 is provided on the fixed sidewall fixed to the second side panel 32. The first and second spring claws 331, 332 are formed through blanking and bending on the corresponding sidewalls. Both the first and second spring claws 331, 332 on the same connecting tube 33 are bent toward the interior of the tube. The corresponding side panels can cover the gaps left by the spring claws on the fixed sidewalls to ensure shielding. The spring claws bend inwardly toward the connecting tube 33. Both the first and second spring claws 331, 332 are cantilever structures, extending in the direction c in Figure 3 , with the first and second spring claws 331, 332 extending in opposite directions.

[0034] As shown in Figures 1, 3, 4, 5, 6 and 8, the connecting cylinders 33 of the shielding member 3 are located on both sides of the shielding isolation cylinder 13 in the spacing direction of each shielding isolation cylinder 13 in the same row. The connector housing 1 is provided with grounding through-holes 14 corresponding to the connecting cylinders 33 of each shielding member 3. The male end grounding pin of the male connector 200 passes through the grounding through-hole 14 to extend into the connecting cylinder 33. The male end grounding pin is in conductive contact with the first spring claw 331 and the second spring claw 332. The root of the first spring claw 331 is close to the grounding through-hole 14 and extends in the direction away from the grounding through-hole 14. The root of the second spring claw 332 is away from the grounding through-hole The first and second spring claws 331, 332 are provided with an inwardly curved portion at the ends away from the roots, and the curved portion constitutes a grounding contact portion. When the male grounding pin is inserted into the connecting cylinder 33, it first contacts the grounding contact portion of the second spring claw 332, and then contacts both the first and second spring claws 331, 332. In this way, two contacts are formed in the extension direction of the center line of the connecting cylinder 33. The extension direction of the center line of the connecting cylinder 33 is the direction c in Figure 3, which is also the plug-in direction of the connector. The short pile of the male grounding pin can be eliminated by the two contacts, thereby improving the transmission performance.

[0035] After the shielding member 3 is installed on the connector housing 1, the first side plate 31 and the second side plate 32 of the shielding member 3 are opposite in the spacing direction between the two adjacent rows of shielding isolation tubes 13. The first side plate 31 and the second side plate 32 are respectively tightly fitted with the two side walls of the shielding isolation tubes 13 in the spacing direction between the two adjacent rows of shielding isolation tubes 13, so that the shielding member 3 is securely installed. The two adjacent shielding members 3 are in conductive contact. The first side plate 31 of one of the two adjacent shielding members 3 is in contact with the second side plate 32 of the other shielding member 3. The first side plates 31 and the second side plates 32 of the two adjacent shielding members 3 are installed in the gap between the two adjacent rows of shielding isolation tubes 13. The shielding members 3 are electrically connected to each other, thereby improving the shielding effect.

[0036] As shown in Figures 1, 2 and 8, a notch is provided on the edge of the shielding sheet 22 of the terminal module 2 near the plug-in end of the signal terminal 21. This notch is not shown in the figure. After the terminal module 2 is installed on the connector housing 1, the edge of the partition side wall of the connecting cylinder 33 facing the terminal module 2 is snapped into the notch on the edge of the shielding sheet 22 of the terminal module 2 for conductive contact. The corresponding edge of the connecting cylinder 33 constitutes a contact portion that is in conductive contact with the shielding sheet 22.

[0037] In other embodiments, only one row of shielding isolation cylinders may be provided on the connector housing, with one row having two shielding isolation cylinders. Accordingly, there are three shielding connectors on the shielding component, and the shielding component has two shielding cavities.

[0038] In other implementations, the shielding connector may also be a connecting plate.

[0039] In other implementations, the shielding member may also be an integrally formed frame structure, the shielding connector is a partition wall, and the shielding side wall is integrally connected to the partition wall.

[0040] In other embodiments, the grounding contact portion may be provided at only one location on a connecting tube.

[0041] In other implementations, the ground contact portion may also be an arched protrusion on the side wall of the connecting tube.

[0042] In other embodiments, the side plates of the shielding member may also abut against the shielding sheet of the terminal module to achieve conductive contact.

[0043] In other embodiments, the directions of the first spring claw and the second spring claw may also be consistent, and the contact parts of the two spring claws with the male ground pin may be staggered.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
