[0040] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] It should be noted that the definitions of "front, back, left, right, up, and down" in this application are all based on... Figure 1 For the sake of accuracy, among which Figure 1 In the diagram, the X direction is the front-back direction, the Y direction is perpendicular to the X direction, the Y direction is the left-right direction, the Z direction is perpendicular to both the X and Y directions, and the Z direction is the up-down direction.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0043] refer to Figure 1 As shown, Figure 1 The present application provides a high-speed connector 1, which is a male connector for connecting and mating with a female connector, including a plurality of terminal groups 10, a fixed housing 11, and a fixed metal frame 12 for fixing the plurality of terminal groups 10.

[0044] refer to Figure 2 As shown, the plurality of terminal groups 10 include a plurality of first terminal groups 10a and a plurality of second terminal groups 10b arranged in a staggered manner along the left and right direction. Both the first terminal groups 10a and the second terminal groups 10b include a plurality of conductive terminals arranged in a vertical direction and an insulating plate 300a / 300b formed and wrapped around the plurality of conductive terminals.

[0045] The conductive terminals include ground terminals 100a / 100b and signal terminals 200a / 200b arranged in the up-down direction. In the same terminal group, the ground terminals 100a / 100b are arranged at intervals, and the signal terminals 200a / 200b are arranged between two ground terminals 100a / 100b. Adjacent two signal terminals 200a / 200b form a signal pair.

[0046] Further, the first terminal group 10a and the second terminal group 10b each further include an additional signal terminal 210a / 210b. In adjacent two terminal groups, the additional signal terminal 210a of the first terminal group 10a is arranged as the last one in the up-down direction (i.e. the first one from bottom to top in all terminals), and the additional signal terminal 210b of the second terminal group 10b is arranged as the first one in the up-down direction. That is, the conductive terminals of the first terminal group 10a are arranged as ground terminal 100a, signal terminal 200a, signal terminal 200a, …, signal terminal 200a, signal terminal 200a, ground terminal 100a, additional signal terminal 210a in the up-down direction, and the conductive terminals of the adjacent second terminal group 10b are arranged as additional signal terminal 210b, ground terminal 100b, signal terminal 200b, signal terminal 200b, …, signal terminal 200b, signal terminal 200b, ground terminal 100b.

[0047] Reference Figures 3 to 9 As shown in the figure, the ground terminals 100a / 100b and the signal terminals 200a / 200b are held in the insulating plate 300a / 300b, and each include a holding section 102 embedded in the insulating plate 300a / 300b, a contact section 103 extending forward from one end of the holding section 102 to the front end of the insulating plate 300a / 300b, and a terminal leg 104 extending downward from the other end of the holding section 102 to the lower end of the insulating plate 300a / 300b. The contact section 103 is used for contact connection with the terminals of the female connector to realize the passage.

[0048] The insulating plate 300a / 300b includes a first surface 301 and a second surface 302 arranged oppositely, and a conductive shielding sheet 400a / 400b is arranged on the first surface 301. The conductive shielding sheet 400a / 400b is provided with a protrusion 401 facing the second surface 302, and the protrusion 401 is connected with the ground terminal 100a / 100b through the insulating plate 300a / 300b.

[0049] In the first terminal group 10a and the second terminal group 10b, a plurality of first springs 1021 are provided on the retaining section 102 of the grounding terminal 100a / 100b, and the first springs 1021 are bent toward the protrusion 401 of the conductive shielding plate 400a / 400b; in the second terminal group 10b, in the top-to-bottom direction, a second spring 1022 is also provided on the grounding terminal 100b, and the second spring is bent toward the protrusion 401 of the conductive shielding plate 400b.

[0050] A second opening 305 is provided on the insulating plate 300a / 300b at the position corresponding to the first spring 1021 and the second spring 1022. The first spring 1021 is connected to the protrusion 401 of the conductive shielding plate 400a / 400b through the second opening 305 to achieve a common ground. The second spring 1022 is bent toward the protrusion 401 of the conductive shielding plate 400a / 400b and connected to achieve a common ground, which has a better shielding effect and improves signal crosstalk.

[0051] Further reference Figure 5 and Figure 10 As shown, since an additional signal terminal 210a is provided below the bottommost ground terminal 100a in the first terminal group 10a, and referring to... Figure 6 and Figure 11 As shown, however, no terminal is provided below the bottommost ground terminal 100b in the second terminal group 10b. This causes the retaining section 102 of the bottommost ground terminal 100b in the second terminal group 10b to be closer to the lower end of the high-speed connector 1 in the vertical direction and closer to the mating end of the high-speed connector 1 in the front-back direction compared to the bottommost ground terminal 100a in the first terminal group 10a. This results in the extended space of the retaining section 102 of the bottommost ground terminal 100a in the first terminal group 10a being greater than that of the bottommost ground terminal 100b in the second terminal group 10b. Therefore, the extension directions of the first spring 1021 and the second spring 1022 on the retaining section 102 of the bottommost ground terminals 100a / 100b in the first terminal group 10a and the second terminal group 10b are different. Preferably, the first spring 1021 on the retaining section 102 of the bottommost grounding terminal 100a in the first terminal group 10a extends along the front-back direction when viewed from the side, and the second spring 1022 on the retaining section 102 of the bottommost grounding terminal 100b in the second terminal group 10b extends along the vertical direction when viewed from the side, thereby making reasonable use of product space.

The insulating plate 300a / 300b is provided with a positioning column 303 at the position corresponding to the positioning hole 402 of the conductive shielding sheet 400a / 400b. The conductive shielding sheet 400a / 400b is fixed on the first surface 301 of the insulating plate 300a / 300b through the cooperation of the positioning column 303 and the positioning hole 402.

[0053] Referring to Figure 3 , Figure 4 and Figure 8 As shown in the drawings, the first terminal group 10a and the second terminal group 10b further include a grounding sheet 500, the grounding sheet 500 is arranged on the second surface 302 of the insulating plate 300a / 300b and located at one end of the contact section 103.
