Background Art

[0002] As technology advances, the demand for faster data rates is increasing. High-density, high-speed backplane connectors have created a new industry situation and become a benchmark for signal integrity. Large data centers of some large commercial groups have benefited greatly from this.

[0003] Nowadays, it is necessary to increase the transmission rate of the connector to 25Gbps~56Gbps. However, in the traditional design, since the male connector usually adopts a straight male terminal and the female connector adopts an elastic female terminal, when the two are matched with each other, it is easy to leave residual roots due to the straight design of the male terminal. Especially when the high-frequency signal rises to 18GHz, the resonance phenomenon caused by the residual roots will be more obvious, thereby affecting the high-speed and high-frequency signal transmission performance.

[0004] Therefore, it is necessary to provide a high-speed backplane connector and connector system with safer and more reliable signal transmission, and excellent signal transmission quality, so as to meet the high-speed requirements of high-speed communication systems. Summary of the invention

[0005] The main purpose of the present invention is to provide a high-speed backplane connector, whose signal terminals adopt a Z-shaped branch structure, have reliable electrical contact, and can meet the requirements of high-density and high-speed signal transmission.

[0006] Another object of the present invention is to provide a connector system, in which the signal terminals of the male and female connectors both adopt a Z-shaped branching structure, have reliable electrical contact, and can meet the requirements of high-density and high-speed signal transmission.

[0007] Other purposes and advantages of the present invention can be further understood from the technical features disclosed in the present invention.

[0008] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: A high-speed backplane connector includes an insulating base, and a plurality of terminal modules installed in the insulating base and arranged in parallel.

[0009] In one embodiment, the elastic butt joint section has two parallel Z-shaped branches, and the two parallel Z-shaped branches are staggered due to the position change of the short straight line segment and the long straight line segment.

[0010] In one embodiment, the elastic docking section has two parallel Z-shaped branches; the long straight line segment of one branch is connected to the head, and the short straight line segment of one branch is connected to the root; the long straight line segment of the other branch is connected to the root, and the short straight line segment of the other branch is connected to the head.

[0011] In one embodiment, each terminal module also includes a row of ground terminals, which are spaced between the row of signal terminals; wherein the signal terminals (S) and the ground terminals (G) in the same row are arranged in the manner of GSSGSSGS and / or SGSSGSSG, and the signal terminals (S) and the ground terminals (G) in two adjacent rows are arranged alternately in these two manners.

[0013] In one embodiment, the row of grounding terminals in the terminal module are connected together via a grounding plate, and the grounding plate is fixed to one side of the insulating bracket.

[0014] To achieve the above-mentioned purpose, the present invention also adopts the following technical solution: A connector system includes: a female connector and a male connector. The female connector includes a plurality of terminal modules arranged in parallel, each terminal module includes a row of female signal terminals; each female signal terminal includes an elastic docking section, an installation section, and an intermediate section located between the elastic docking section and the installation section;

[0015] The male connector includes a plurality of terminal modules arranged in parallel, each terminal module includes a row of male signal terminals; each male signal terminal includes an elastic docking section, an installation section, and an intermediate section located between the elastic docking section and the installation section. The elastic docking sections of the female signal terminal and the male signal terminal each have a head, a root, and at least one branch connecting the head and the root; wherein the branch is Z-shaped, having a short straight line section, a long straight line section, and a bending section connecting the short straight line section and the long straight line section. When the male signal terminal and the female signal terminal are mated with each other, the head of the male signal terminal abuts against the root of the female signal terminal, the head of the female signal terminal abuts against the root of the male signal terminal, and at the same time, the long straight line section of the branch of the male signal terminal forms an electrical contact with the long straight line section of the branch of the female signal terminal.

[0016] In one embodiment, the male signal terminal and the branch of the female signal terminal are complementary; when the long straight segment of the branch of the female signal terminal is connected to the root of the female signal terminal, the corresponding long straight segment of the branch of the male signal terminal is connected to the head of the male signal terminal.

[0017] In one embodiment, the elastic docking sections of the female signal terminal and the male signal terminal each have two parallel Z-shaped branches; the two parallel Z-shaped branches of the female signal terminal are complementary to the two parallel Z-shaped branches of the male signal terminal.

[0052] The following embodiments are described with reference to the attached drawings to illustrate specific embodiments of the present invention. Directional terms mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but are not used to limit the present invention.

[0053] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the high-speed backplane connector 1 of the present invention includes an insulating base 10 and a plurality of terminal modules 20 installed in the insulating base 10 and arranged in parallel from left to right.

[0054] like Figure 3 , Figure 4 As shown, the insulating base 10 has a docking side 101, a mounting side 102, and a plurality of vertical walls 103 extending from the mounting side 102 to the docking side 101, and a row of terminal grooves 104 are formed on both sides of at least one of the vertical walls 103 to fix the corresponding terminal module 20.

[0055] like Figure 5 , Figure 6 As shown, each terminal module 20 includes at least one insulating support 21 and a row of signal terminals 30 fixed in the insulating support 21. In this embodiment, each terminal module 20 also includes a row of grounding terminals 40, which are connected together by a grounding plate 41 to form a one-piece structure. The grounding plate 41 is fixed to one side of the insulating support 21 to provide electromagnetic shielding and grounding performance, and the row of grounding terminals 40 is spaced between the row of signal terminals 30 and arranged in a row.

[0056] In this embodiment, the so-called interval arrangement means that in the same column, the signal terminals 30 (S) and the ground terminals 40 (G) are arranged in the manner of GSSGSSGS and / or SGSSGSSG. Of course, in other embodiments, the signal terminals 30 in the column and the ground terminals 40 in the column can also be arranged in other intervals to achieve better signal transmission performance.

[0057] In more detail, in this embodiment, the terminal rows of two adjacent terminal modules 20 are arranged alternately in two arrangements. For example, the terminal arrangement of one terminal module 20 is GSSGSSGS, while the terminal arrangement of the other terminal module 20 is SGSSGSSG. This alternating arrangement can further meet the high-frequency signal transmission requirements.

[0058] During installation, the terminal module 20 is pushed forward from the installation side 102 of the insulating base 10, so that the signal terminal 30 and the ground terminal 40 extend along the corresponding terminal groove 104 toward the docking side 101 of the insulating base 10, and the insulating bracket 21 is fixed in the insulating base 10 to ensure the stability of the structure.

[0059] like Figure 6 As shown, each signal terminal 30 includes an elastic docking section 31, a mounting section 32, and a middle section 33 located between the elastic docking section 31 and the mounting section 32. In this embodiment, the elastic docking section 31 and the mounting section 32 are located at opposite ends (front end and rear end) of the middle section 33. Figure 5 , Figure 6As shown, the signal terminal 30 is integrated with the insulating bracket 21 by injection molding, wherein the insulating bracket 21 is a vertical plate-shaped structure, the elastic docking section 31 extends from the front edge of the insulating bracket 21, the mounting section 32 extends from the rear edge of the insulating bracket 21, and the middle section 33 is retained in the insulating bracket 21. In this embodiment, the signal terminal 30 is substantially linear, while in other embodiments, the signal terminal 30 may be right-angled (i.e., L-shaped).

[0060] The signal terminals 30 of the high-speed backplane connector 1 of the present invention will be further described below.

[0061] Please refer to Figure 6 As shown, the elastic docking section 31 of the signal terminal 30 of the high-speed backplane connector 1 of the present invention has a head 310, a root 311, and at least one branch 312 connecting the head 310 and the root 311. The branch 312 is generally Z-shaped, and has a short straight segment 313, a long straight segment 314, and a bent segment 315 connecting the short straight segment 313 and the long straight segment 314. In one embodiment, the long straight segment 314 of the branch 312 is connected to the head 310 and the long straight segment 314 is coplanar with the head 310, and the short straight segment 313 is connected to the root 311; or: the long straight segment 314 of the branch 312 is connected to the root 311 and the long straight segment 314 is coplanar with the root 311, and the short straight segment 313 is connected to the head 310.

[0062] It should be emphasized that in the present invention, the so-called branch 312 is in a Z shape, but not an absolute Z shape, and it also includes a situation close to a Z shape or approximate to an L shape. For example: when the short straight line segment 313 is coplanar with the root 311 or the head 310, an absolute Z shape is formed; and when the short straight line segment 313 is slightly inclined and forms an angle with the root 311 or the head 310, the short straight line segment 313, the long straight line segment 314 and the bent segment 315 form a shape close to a Z shape or a shape close to an L shape; or when the short straight line segment 313 is very short or extremely short and almost disappears and is close to an L shape, these all fall within the description scope of the Z shape of the present invention.

[0063] It should also be noted that "the long straight line segment 314 and the head 310 are coplanar" means that most of the structures of the two are in the same plane. Of course, according to the electrical design requirements, there will be a small part of the structure that is out of the plane where the two are located. For example: an arc-shaped contact portion 3100 is formed on the head 310, which protrudes outward to facilitate elastic docking with the docking connector.

[0064] exist Figure 6In the first embodiment shown, the elastic docking section 31 of the signal terminal 30 of the high-speed backplane connector 1 of the present invention has two parallel Z-shaped branches 312, and the two Z-shaped branches 312 are staggered by the position change of the short straight section 313 and the long straight section 314. In detail, the long straight section 314 of one branch 312 is connected to the head 310, and the short straight section 313 is connected to the root 311; the long straight section 314 of the other branch 312 is connected to the root 311, and the short straight section 313 is connected to the head 310. Through this design, the two Z-shaped branches 312 are staggered, which can not only form a good support for the elastic docking section 31, but also use the long straight section 314 to extend the electrical contact surface with the docking terminal, thereby reducing the residual root.

[0065] In a preferred embodiment, the elastic butting section 31 of the signal terminal 30 of the present invention has two branches 312. However, it should be noted that the number of the branches 312 can also be changed to meet different structural design requirements.

[0066] In the first embodiment, if Figure 6 As shown, the elastic butting sections 31 of two adjacent signal terminals 30 (30-1 and 30-2) adopt the same structure. Fig. 9 As shown, the elastic butt joint sections 31a of two adjacent signal terminals 30a (30a-1 and 30a-2) adopt a symmetrical structure, which can also achieve the effect of reducing residual roots.

[0067] like Figure 5 , Figure 6 As shown, each grounding terminal 40 includes an elastic mating end 401 and a fixed end 402, and the elastic mating end 401 and the fixed end 402 of each row of grounding terminals 40 are connected through the grounding plate 41. In this embodiment, the elastic mating end 401 and the fixed end 402 are respectively located at two opposite edges of the grounding plate 41. The grounding terminal 40 is installed to one side of the insulating bracket 21 through the grounding plate 41, or is combined with the insulating bracket 21 as a whole by injection molding. The elastic mating end 401 extends from the front edge of the insulating bracket 21, the fixed end 402 extends from the rear edge of the insulating bracket 21, and the grounding plate 41 is retained on the insulating bracket 21. Similarly, the fixed end 402 of the grounding terminal 40 also has a fisheye structure to be firmly inserted into the corresponding circuit board through hole.

[0068] In the first embodiment, the width of the elastic mating end 401 of each ground terminal 40 is substantially greater than the width of the elastic docking section 31 of each signal terminal 30. Of course, in other embodiments, the width of the ground terminal 40 can also be adjusted according to electrical requirements.

[0069] like Fig.12 , Fig.13 As shown, in the first embodiment, the high-speed backplane connector 1 of the present invention is a female connector 1, and its signal terminal 30 is a female signal terminal 30, which can cooperate with the signal terminal (male signal terminal 80) of another high-speed backplane connector (male connector 8) to form a connector system 100, thereby connecting two circuit boards (motherboard and daughterboard, not shown) to achieve high-speed signal transmission.

[0070] like Figure 7 As shown, the structure of the terminal module 81 of the male connector 8 is basically the same as that of the terminal module 20 of the female connector 1 .

[0071] For example, the elastic docking section 800 of the male signal terminal 80 also has a head 810, a root 811, and at least one Z-shaped branch 812 connecting the head 810 and the root 811. In the first embodiment, the elastic docking section 800 of the male signal terminal 80 has two parallel Z-shaped branches 812 to correspond to the two branches 312 of the female connector 1. The elastic docking section 800 of the male signal terminal 80 is symmetrical with the elastic docking section 31 of the corresponding female signal terminal 30, so that a complementary structure can be formed when mated.

[0072] In more detail, in the first embodiment, the difference between the male signal terminal 80 and the female signal terminal 30 is that the branches 812 and 312 of the two are complementary to each other to achieve mutual matching. That is to say, the two parallel Z-shaped branches 312 of the female signal terminal 30 and the two parallel Z-shaped branches 812 of the male signal terminal 80 are complementary in structure when they are matched. In detail, the long straight line segment 314 of one of the branches 312 of one of the female signal terminals 30 is connected to the root 311 of the female signal terminal 30 and the long straight line segment 314 is coplanar with the root 311, then the long straight line segment 814 of the corresponding branch 812 of the corresponding male signal terminal 80 is connected to the head 810 of the male signal terminal 80 and the long straight line segment 814 is coplanar with the head 810. Of course, if the long straight line segment 314 of the other branch 312 of one of the female signal terminals 30 is connected to the head 310 of the female signal terminal 30 and the long straight line segment 314 is coplanar with the head 310, then the long straight line segment 814 of the corresponding branch 812 of the corresponding male signal terminal 80 is connected to the root 811 of the male signal terminal 80 and the long straight line segment 814 is coplanar with the root 811.

[0073] When the male signal terminal 80 and the female signal terminal 30 are mated with each other, the head 810 of the male signal terminal 80 abuts against the root 311 or the long straight segment 314 of the female signal terminal 30 , and the head 310 of the female signal terminal 30 abuts against the root 811 or the long straight segment 814 of the male signal terminal 80 .

[0074] For example, Figure 8 As shown, it shows a schematic diagram of one of the mutual matching of the male signal terminal 80 and the female signal terminal 30. When the male signal terminal 80 and the female signal terminal 30 are mutually matched, the head 810 of the male signal terminal 80 abuts against the root 311 of the female signal terminal 30, and the head 310 of the female signal terminal 30 abuts against the root 811 of the male signal terminal 80. At the same time, the long straight segments 814 of the two branches 812 of the male signal terminal 80 will be attached to the corresponding long straight segments 314 of the two branches 312 of the female signal terminal 30 to form electrical contact; through the contact between the head 310 and the root 311, and the contact between the long straight segments 314 of the two branches 312, the present invention can reduce the occurrence of residual roots, avoid resonance in high-speed signal transmission, and thus optimize signal quality.

[0075] For example, Fig. 9 2 is another schematic diagram of the mutual mating of the male signal terminal 80 and the female signal terminal 30. The head 810 of the male signal terminal 80 abuts against the long straight section 314 of one branch 312 of the female signal terminal 30, and the head 310 of the female signal terminal 30 abuts against the long straight section 814 of one branch 812 of the male signal terminal 80. Similarly, when the male signal terminal 80 and the female signal terminal 30 are in the mating state, the occurrence of residual roots can also be reduced.

[0076] like Fig.10As shown, in the second embodiment, the signal terminals 80a, 30a of the male connector 8a and the female connector 1a of the connector system of the present invention also adopt a double Z-shaped branch structure. The difference between the second embodiment and the first embodiment is that the elastic butt joint sections 31a of the two adjacent signal terminals 30a in the second embodiment adopt a symmetrical structure. Here, the female signal terminal is taken as an example to illustrate the difference between the second embodiment and the first embodiment. In detail, in the two adjacent female signal terminals 30a (30a-1, 30a-2) of the female connector 1a, the long straight section 314a of one branch 312a of one female signal terminal 30a-1 is adjacent to the long straight section 314a of one branch 312a of the other female signal terminal 30a-2, and the long straight section 314a of the other branch 312a of one female signal terminal 30a-1 and the long straight section 314a of the other branch 312a of the other female signal terminal 30a-2 are arranged at the farthest side of the two female signal terminals 30a, thereby forming a symmetrical structure. Similarly, the branches 812a of the two adjacent male signal terminals 80a of the male connector 8a are also symmetrical, and the branches 812a of the male signal terminal 80a and the branches 312a of the female signal terminal 30a are complementary structures to facilitate docking and mutual mating.

[0077] like Fig.11 As shown, in the third embodiment, the signal terminals 80b, 30b of the male connector and the female connector of the connector system of the present invention also adopt a double Z-shaped branch structure.

[0078] Fig.11 The third embodiment shown is Figures 7 to 9 The difference of the first embodiment shown is that the elastic abutting sections 800b and 31b of the male signal terminal 80b and the female signal terminal 30b have the same structure.

[0079] For example, the long straight segment 314b of one of the branches 312b of the female signal terminal 30b is connected to the head 310b of the female signal terminal 30b and the long straight segment 314b is coplanar with the head 310b, and the long straight segment 814b of the corresponding branch 812b of the corresponding male signal terminal 80b is also connected to the head 810b of the male signal terminal 80b and the long straight segment 814b is coplanar with the head 810b.

[0080] When the male signal terminal 80b and the female signal terminal 30b are mated, the head 810b of the male signal terminal 80b contacts the long straight section 314b of the female signal terminal 30b, and the head 310b of the female signal terminal 30b contacts the long straight section 814b of the male signal terminal 80b.

[0081] Please refer to Fig.14 , Fig.15 As shown, the connector system of the present invention ( Figure 8 Insertion loss and return loss simulation curves at different signal frequencies (see the embodiment shown in FIG. Fig.14 It can be seen that when the frequency reaches 15GHz, the insertion loss of the connector system is only about -0.43dB; when the frequency reaches 28GHz, the insertion loss of the connector system is -3dB. Fig.15 It can be seen that the return loss value is negative 21.99dB when the frequency reaches 15GHz, and the return loss value is negative 9.9dB when the frequency reaches 20.5GHz. These indicators can verify that the present invention can indeed achieve satisfactory high-speed performance under high-frequency signals through the Z-shaped branch 312 structure.

[0082] In summary, the high-speed backplane connector 1 and connector system 100 of the present invention improve the docking structure of the signal terminals and adopt a Z-shaped branching structure, which can be suitable for high-density and high-speed (25Gbps~56Gbps) transmission environment and meet the requirements of high-density and high-speed signal transmission.
