[0048] The male connector 200 includes a male housing 201 and a male signal terminal 202 and a male grounding terminal 203 mounted on the male housing 201. The male signal terminal 202 constitutes a signal contact of the adapter connector, and the male grounding terminal 203 constitutes a grounding contact of the adapter connector.

The male grounding terminal 203 is a U-shaped grounding terminal. The male grounding terminal 203 has a U-shaped body located in the male housing 201 and a fisheye end extending out of the male housing 201. The U-shaped body of the male grounding terminal 203 includes two side walls opposite to each other in the front and back and a connecting wall connecting the two side walls. The two side walls opposite to each other in the front and back of the U-shaped body and the connecting wall form a groove. The plug-in end of the male signal terminal 202 is located in the groove. Each differential pair of the male connector 200 corresponds to a male grounding terminal 203, and the plug-in end of the same differential pair is in the same groove. The male signal terminals 202 and the male grounding terminals 203 are arranged in rows, and multiple rows are arranged in the left and right direction corresponding to the terminal module 102. The male signal terminals 202 in the same row are arranged at intervals in the front and back direction. Correspondingly, the male grounding terminals 203 in the same row are arranged at intervals in the front and back direction.

[0049] like Figure 1-9 As shown, the terminal module 102 of the female connector 100 includes an insulator 1, a first shielding sheet 2, a second shielding sheet 3, and a female signal terminal 4 disposed on the insulator 1.

The female signal terminal 4 has a contact end 41 extending downward from the insulator 1 and a fisheye end extending upward from the insulator 1. The contact end 41 is a spring arm structure and is used to contact the male signal terminal 202 of the male connector 200.

[0050] The first shielding sheet 2 and the second shielding sheet 3 are respectively arranged on both sides of the thickness direction of the insulator 1. The first shielding sheet 2 includes a first main body 20 and a plug-in portion, the plug-in portion includes a plurality of contact springs 21, the contact springs 21 are suspended downward based on the first main body 20, and the contact springs 21 are provided with a grounding contact arm 22 and an interconnection contact arm, the grounding contact arm 22 is used to contact the male grounding terminal 203 of the male connector 200, and the interconnection contact arm is used to contact the second shielding sheet 3 of the adjacent terminal module 102. The second shielding sheet 3 includes a second main body 30 and a plug-in area shielding portion 31, the plug-in area shielding portion 31 is a sheet body integrally connected to the second main body 30, the plug-in area shielding portion 31 extends to one side of the contact end 41 of the female signal terminal 4 in the left-right direction, the plug-in area shielding portion 31 of the second shielding sheet 3 is opposite to the contact end 41 in the thickness direction of the insulator 1, the thickness direction of the insulator 1 is the left-right direction, and the plug-in area shielding portion 31 can shield the contact ends 41 of each differential pair of the terminal module 102 on one side. After each terminal module 102 is installed on the female end housing 101, the interconnected contact arm on the contact spring 21 of one of the terminal modules 102 of the adjacent two terminal modules 102 forms contact with the corresponding side of the plug-in area shielding portion 31 of the second shielding sheet 3 of the other terminal module 102, so that the shielding sheets of each terminal module 102 can form a common ground. The second shielding sheet 3 can be used to shield the contact ends 41 of the differential pairs of the terminal modules 102 in the left and right directions, which is beneficial to form a surrounding shield for the contact ends 41 and improve the shielding effect.

[0051] The contact springs 21 on the first shielding sheet 2 are arranged at intervals along the front-to-back direction, and the space between two adjacent contact springs 21 can avoid the contact end 41 of the female signal terminal 4. In the front-to-back direction, there are contact springs 21 on both sides of each differential pair of the terminal module 102, wherein the structure of the frontmost contact spring and the rearmost contact spring is different from the structure of the contact spring between the two, and a grounding contact arm 22 and an interconnection contact arm are respectively provided on the frontmost contact spring and the rearmost contact spring, and two grounding contact arms 22 and two interconnection contact arms are respectively provided on the contact spring between the frontmost contact spring and the rearmost contact spring, and each contact spring between the frontmost contact spring and the rearmost contact spring is respectively located between two adjacent signal terminal pairs, and the interconnection contact arms on the frontmost contact spring and the rearmost contact spring are third interconnection contact arms 25, and the two interconnection contact arms on the contact spring 21 located between two adjacent signal terminal pairs are respectively the first interconnection contact arm 23 and the second interconnection contact arm 24.

[0052] The contact spring 21 located between two adjacent signal terminal pairs has a proximal portion close to the root and a distal portion away from the root. The distal portion is provided with two grounding contact arms 22 in parallel. The two grounding contact arms 22 are respectively in contact with the two male grounding terminals 203 of the male connector 200. The two adjacent grounding contact arms 22 located on both sides of the same differential pair on the two adjacent contact springs 21 are used to contact the same male grounding terminal 203. On the same contact spring 21, the first interconnecting contact arm 23 is located between the two grounding contact arms 22, and the second interconnecting contact arm 24 is arranged on the proximal portion of the contact spring 21. The first interconnecting contact arm 23 and the second interconnecting contact arm 24 are spaced apart along the cantilever direction of the contact spring 21. Both the interconnecting contact arm and the grounding contact arm 22 are cantilever structures. The interconnecting contact arm and the grounding contact arm 22 are formed by blanking and bending. The bending directions of the interconnecting contact arm and the grounding contact arm 22 are opposite. Figure 5 The grounding contact arm 22 of the middle terminal module 102 is bent toward its second shielding sheet 3, and the interconnection contact arm is bent away from its second shielding sheet 3 and toward the second shielding sheet of another terminal module. The first interconnection contact arm 23 and the second interconnection contact arm 24 can both form shielding contact conduction with the corresponding second shielding sheet, which is conducive to reliable shielding.

[0053] The overhang length of the first interconnection contact arm 23 is greater than the overhang length of the second interconnection contact arm 24, and the width of the grounding contact arm 22 is greater than the width of the interconnection contact arm. Figure 3 The a direction in the figure. The abutment between the grounding contact arm 22 and the male grounding terminal 203 is more responsible for the interconnection and transmission. The abutment between the interconnection contact arm and the second shielding sheet 3 of the other terminal module 102 is used to provide an anti-crosstalk shielding reference point. Therefore, the width of the grounding contact arm 22 is greater than that of the interconnection contact arm. The first interconnection contact arm 23 is at the end of the contact spring 21, and has a more obvious effect on the insertion and extraction force of the product during the insertion and extraction process. Therefore, the length of the first interconnection contact arm 23 is greater than the length of the second interconnection contact arm 24.

[0054] The shielding portion 31 of the plug-in area of ​​the second shielding sheet 3 is provided with a conductive contact portion for contacting the male grounding terminal 203 of the male connector 200. The conductive contact portion includes two conductive spring arms 32. The conductive spring arms 32 are cantilever structures. The cantilever directions of each conductive spring arm 32 are consistent, and the cantilever direction of the conductive spring arm 32 is consistent with the insertion direction of the male grounding terminal 203. The conductive spring arm 32 is bent toward the side where the contact end 41 of the differential pair is located. When the male connector 200 and the female connector 100 are plugged in, the male grounding terminal 203 slides and overlaps along the cantilever direction of the conductive spring arm 32, and there is no risk of hitting the pin during the plugging process. The two conductive spring arms 32 of the same conductive contact portion are staggered front and back to stagger the plugging and unplugging force peaks, so that the overall plugging and unplugging process is smoother.

The first body 20 is provided with a fisheye at one end away from the plug-in portion, and the second body 30 is provided with a fisheye at one end away from the plug-in area shielding portion 31. The conductive buckle plate 103 is provided with avoidance holes for avoiding the fisheye ends of the differential pairs of the terminal module 102 and through holes for the fisheye parts on the shielding sheet to pass through. The conductive buckle plate 103 is in conductive contact with both the first shielding sheet 2 and the second shielding sheet 3.

[0056] After each terminal module 102 is mounted on the female housing 101, Fig. 9 The interconnecting contact arm on the contact spring sheet 21 of one of the two adjacent terminal modules 102 forms contact with the corresponding side of the plug-in area shielding portion 31 of the second shielding sheet 3 of the other terminal module 102. After the male connector 200 and the female connector 100 are plugged in, the plug-in end of the male signal terminal 202 extends to one side of the contact end 41 of the female signal terminal 4 and forms a conductive contact. The U-shaped body of the male grounding terminal 203 extends between the first shielding sheet 2 and the second shielding sheet 3. The top surfaces of the front and rear opposite side walls of the U-shaped body of the male grounding terminal 203 abut against the grounding contact arm 22, and the connecting wall connecting the two side walls of the U-shaped body abuts against the conductive spring arm 32.

[0057] In other implementations, the ground contact arm and the interconnection contact arm may also be independently provided, and both the ground contact arm and the interconnection contact arm are cantilevers based on the first body. In this case, only one interconnection contact arm may be provided.

[0058] In other implementations, only one interconnection contact arm may be provided on the same contact spring, or three interconnection contact arms may be provided if space permits.

[0059] In other implementations, the lengths of the interconnected contact arms on the same contact spring may also be the same.

[0060] In other implementations, the conductive contact portion may also be a raised protrusion.
