Detailed Description

The following description of the embodiments refers to the accompanying drawings for illustrating the specific embodiments in which the invention may be practiced. The directional terms used in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., refer to the directions of the attached drawings. Accordingly, the directional terms used are used for explanation and understanding of the present invention, and are not used for limiting the present invention.

Referring to fig. 1, 2, 3 and 4, the high-speed backplane connector 1 of the present invention includes an insulating base 10, and a plurality of terminal modules 20 mounted in the insulating base 10 and arranged side by side from left to right.

As shown in fig. 3 and 4, the insulating base 10 has a mating side 101, a mounting side 102, and a plurality of rows of vertical walls 103 extending from the mounting side 102 to the mating side 101, and a row of terminal slots 104 is formed on each of two sides of at least one of the vertical walls 103 for fixing the corresponding terminal module 20.

As shown in fig. 5 and 6, each terminal module 20 at least includes an insulating support 21 and a row of signal terminals 30 fixed in the insulating support 21. In this embodiment, each terminal module 20 further includes a row of ground terminals 40, the row of ground terminals 40 are connected together by a ground plate 41 to form a one-piece structure, the ground plate 41 is fixed on one side of the insulating frame 21 for providing electromagnetic shielding and grounding performance, and the row of ground terminals 40 are spaced between the row of signal terminals 30 and are arranged in a row.

In the present embodiment, the interval setting means: 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 row of signal terminals 30 and the row of ground terminals 40 may be arranged at other intervals to achieve better signal transmission performance.

In more detail, in the present embodiment, the terminal rows of two adjacent terminal modules 20 are alternately arranged in two arrangements. For example, the terminal arrangement of one of the terminal modules 20 is GSSGSSGS, and the terminal arrangement of the other terminal module 20 is SGSSGSSG, which can further satisfy the requirement of high frequency signal transmission.

When mounting, the terminal module 20 is pushed forward from the mounting side 102 of the insulating base 10, so that the signal terminals 30 and the ground terminals 40 both extend along the corresponding terminal slots 104 to the mating side 101 of the insulating base 10, and the insulating bracket 21 is clipped in the insulating base 10 to ensure structural stability.

As shown in fig. 6, each signal terminal 30 includes an elastic abutting section 31, a mounting section 32, and an intermediate section 33 located between the elastic abutting section 31 and the mounting section 32. In the present embodiment, the elastic butt-joint section 31 and the mounting section 32 are respectively located at two opposite ends (front end and rear end) of the middle section 33. As shown in fig. 5 and 6, the signal terminal 30 and the insulating support 21 are integrated by injection molding, wherein the insulating support 21 has a vertical plate-like structure, the elastic abutting section 31 extends from a front edge of the insulating support 21, the mounting section 32 extends from a rear edge of the insulating support 21, and the middle section 33 is retained in the insulating support 21. In the present embodiment, the signal terminals 30 are substantially linear, while in other embodiments, the signal terminals 30 may be right-angled (i.e., L-shaped).

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

Referring to fig. 6, the flexible mating segment 31 of the signal terminal 30 of the high-speed backplane connector 1 of the present invention has a head portion 310, a root portion 311, and at least one branch 312 connecting the head portion 310 and the root portion 311. The branch 312 is substantially Z-shaped and has a short straight line segment 313, a long straight line segment 314, and a bending segment 315 connecting the short straight line segment 313 and the long straight line 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, with its short straight segment 313 connected to the root 311; or the following steps: the long straight section 314 of the branch 312 is connected to the root 311 and the long straight section 314 is coplanar with the root 311, with its short straight section 313 connected to the head 310.

It is emphasized that in the present invention, the branch 312 is Z-shaped, but not absolute Z-shaped, and includes near Z-shaped or near L-shaped. For example: when the short straight section 313 is coplanar with the root 311 or the head 310, an absolute Z-shape is formed; when the short straight line segment 313 is slightly inclined to form an included angle with the root 311 or the head 310, the short straight line segment 313, the long straight line segment 314 and the bending segment 315 form a shape close to a Z shape or a shape close to an L shape; alternatively, when the short straight section 313 is very short or very short and almost vanishing to approximate an L shape, these are all within the description of the Z shape of the present invention.

It should also be noted that "the long straight line portion 314 is coplanar with the head portion 310" means that most of the structures of the two are in the same plane. Of course, depending on the electrical design requirements, there may be a small portion of the structure out of the plane of the two. For example: an arc-shaped contact portion 3100 is formed on the header 310 to protrude outward, thereby facilitating elastic mating with a mating connector.

In the first embodiment shown in fig. 6, the elastic mating segment 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 arranged in a staggered manner by changing the positions of the short straight segment 313 and the long straight segment 314. In detail, a long straight line portion 314 of one branch 312 is connected to the head portion 310, and a short straight line portion 313 thereof is connected to the root portion 311; the long straight segment 314 of the other branch 312 is connected to the root 311 and its short straight segment 313 is connected to the head 310. Through the design, the two Z-shaped branches 312 are arranged in a staggered manner, so that a good supporting effect can be formed for the elastic butt joint section 31, and the long straight line section 314 can be used for prolonging the electrical contact surface with the butt joint terminal, so that the stub is reduced.

In the preferred embodiment, the resilient mating segment 31 of the signal terminal 30 of the present invention has two branches 312. It should be noted that the number of branches 312 may also be varied to meet different structural design requirements.

In the first embodiment, as shown in fig. 6, the elastic butting sections 31 of the adjacent two signal terminals 30(30-1 and 30-2) adopt the same structure. In the second embodiment, as shown in fig. 9, the elastic butt-joint sections 31a of the two adjacent signal terminals 30a (30a-1 and 30a-2) adopt a symmetrical structure, and the effect of reducing stub can also be achieved.

As shown in fig. 5 and 6, each ground terminal 40 includes a resilient mating end 401 and a fixed end 402, and the resilient mating end 401 and the fixed end 402 of each row of ground terminals 40 are connected by the ground plate 41. In this embodiment, the elastic mating end 401 and the fixed end 402 are respectively located at two opposite edges of the ground plate 41. The ground terminal 40 is mounted to one side of the insulating holder 21 through the ground plate 41 or integrated with the insulating holder 21 by injection molding. Wherein the resilient mating end 401 extends from the front edge of the insulating support 21, the fixed end 402 extends from the rear edge of the insulating support 21, and the ground plate 41 is retained on the insulating support 21. Similarly, the fixed end 402 of the ground terminal 40 has a fish-eye structure for being inserted into the corresponding through hole of the circuit board.

In the first embodiment, the width of the resilient mating end 401 of each ground terminal 40 is substantially greater than the width of the resilient mating segment 31 of each signal terminal 30. Of course, in other embodiments, the width of the ground terminal 40 may be adjusted according to the electrical requirement.

As shown in fig. 12 and 13, in the first embodiment, the high-speed backplane connector 1 according to the present invention is a female connector 1, and the signal terminals 30 thereof are female signal terminals 30, which can be matched with the signal terminals (male signal terminals 80) of another high-speed backplane connector (male connector 8) to form a connector system 100, so as to connect two circuit boards (a motherboard and a daughter board, not shown) to realize high-speed signal transmission.

As shown in fig. 7, the terminal module 81 of the male end connector 8 has substantially the same structure as the terminal module 20 of the female end connector 1.

For example: the resilient mating segment 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 resilient mating section 800 of the male signal terminal 80 has two Z-shaped branches 812 juxtaposed to correspond to the two branches 312 of the female connector 1. The resilient mating segment 800 of the male signal terminal 80 is structurally symmetrical to the resilient mating segment 31 of the corresponding female signal terminal 30, so as to form a complementary structure when mated.

In more detail, in the first embodiment, the male terminal signal terminal 80 is different from the female terminal signal terminal 30 in that: the two

branches

812, 312 are complementary to each other to achieve interworking. That is, 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 configuration when mated with each other. In detail, the long straight line 314 of one branch 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 314 is coplanar with the root 311, and the long straight line 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 814 is coplanar with the head 810. Of course, the long straight line 314 of the other branch 312 of one of the female signal terminals 30 is connected to the head portion 310 of the female signal terminal 30 and the long straight line 314 is coplanar with the head portion 310, and the long straight line 814 of the corresponding branch 812 of the corresponding male signal terminal 80 is connected to the root portion 811 of the male signal terminal 80 and the long straight line 814 is coplanar with the root portion 811.

When the male signal terminal 80 is mated with the female signal terminal 30, the head 810 of the male signal terminal 80 abuts against the root 311 or the long straight line 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 line 814 of the male signal terminal 80.

For example, as shown in fig. 8, which shows an interworking schematic diagram of the male signal terminal 80 and the female signal terminal 30, when the male signal terminal 80 is interacted with the female signal terminal 30, the head 810 of the male signal terminal 80 abuts against the root 311 of the female signal terminal 30, the head 310 of the female signal terminal 30 abuts against the root 811 of the male signal terminal 80, and meanwhile, the long straight line segments 814 of the two branches 812 of the male signal terminal 80 abut against the long straight line segments 314 of the two corresponding 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 line segments 314 of the two branches 312, the invention can reduce the occurrence of stub and avoid generating resonance in high-speed signal transmission, thereby optimizing the signal quality.

For another example, fig. 9 is another schematic diagram 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 line 314 of one of the branches 312 of the female signal terminal 30, and the head 310 of the female signal terminal 30 abuts against the long straight line 814 of one of the branches 812 of the male signal terminal 80. Similarly, when the male terminal 80 and the female terminal 30 are in the mated state, the occurrence of stub can be reduced.

As shown in fig. 10, in the second embodiment, the

signal terminals

80a and 30a of the male and female connectors 8a and 1a of the connector system of the present invention also have a double Z-shaped branch structure. The second embodiment differs from the first embodiment described above in that: the elastic abutting sections 31a of the two adjacent signal terminals 30a in the second embodiment have a symmetrical structure, and the difference between the second embodiment and the first embodiment will be described by taking a female-end signal terminal as an example. In detail, in the two adjacent female signal terminals 30a (30a-1, 30a-2) of the female connector 1a, the long straight line segment 314a of one branch 312a of one female signal terminal 30a-1 is adjacent to the long straight line segment 314a of one branch 312a of the other female signal terminal 30a-2, and the long straight line segment 314a of the other branch 312a of one female signal terminal 30a-1 and the long straight line segment 314a of the other branch 312a of the other female signal terminal 30a-2 are arranged at the farthest sides of the two female signal terminals 30a, so as to form 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 terminals 80a and the branches 312a of the female signal terminals 30a are complementary structures to facilitate mating.

As shown in fig. 11, in the third embodiment, the

signal terminals

80b and 30b of the male and female connectors of the connector system of the present invention also have a double Z-shaped branch structure.

The third embodiment shown in fig. 11 differs from the first embodiment shown in fig. 7 to 9 in that: the male signal terminal 80b and the female signal terminal 30b have the same structure of the elastic mating sections 800b and 31 b.

For example: the long straight line 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 line segment 314b is coplanar with the head 310b, while the long straight line 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 line segment 814b is coplanar with the head 810 b.

When the male signal terminal 80b is mated with the female signal terminal 30b, the head 810b of the male signal terminal 80b abuts against the long straight line 314b of the female signal terminal 30b, and the head 310b of the female signal terminal 30b abuts against the long straight line 814b of the male signal terminal 80 b.

Referring to fig. 14 and 15, a graph showing insertion loss and return loss simulation curves of the connector system (the embodiment shown in fig. 8) of the present invention at different signal frequencies is shown. As can be seen from fig. 14, the insertion loss value of the connector system is minus 0.43dB when the frequency reaches 15 GHz; the insertion loss value of the connector system is minus 3dB when the frequency reaches 28 GHz. As can be seen from FIG. 15, the return loss value is minus 21.99dB when the frequency reaches 15 GHz; the return loss value of the frequency reaching 20.5GHz is minus 9.9 dB. From these indicators, it can be verified that the present invention can indeed achieve satisfactory high-speed performance at high frequency signals through the structure of the Z-shaped branch 312.

In summary, the high-speed backplane connector 1 and the connector system 100 according to the present invention can be applied to high-density and high-speed (25Gbps to 56Gbps) transmission environments by improving the butt joint structure of the signal terminals and adopting the Z-branch structure, so as to meet the requirements of high-density and high-speed signal transmission.
