Description

Technical Field

[0001] The invention belongs to the field of backplanes, and in particular relates to an orthogonal connector with a rotating structure. Background Art

[0002] In modern data communication transmission systems, transmission rates are getting higher and higher. High-speed interconnection systems are widely used in communication networks and data exchange systems. As the core bridge of data communication, high-speed backplane connectors have increasingly higher performance requirements. As equipment develops towards miniaturization and high density, space utilization is increasingly required. Connectors have various layout forms. Orthogonal connectors can achieve 90-degree rotation, which greatly improves space utilization in certain situations.

[0003] High-speed signal transmission in high-speed backplane connectors is mainly achieved through the use of male and female ends. The orthogonal method is mainly achieved by bending the female or male end. Due to the complex structure of the female end, bending has high requirements on spatial layout and process, which is difficult to achieve. The offset bending structure of the male end is not flexible enough, and the bending and misalignment of the signal path can easily lead to a decrease in signal quality transmission and damage the signal integrity (SI).

[0004] like Figure 1 The prior art shown is mainly achieved by offsetting and bending the male signal terminal, but this method causes a large misalignment between the fisheye surface and the pin surface. The high-speed signal suddenly changes in this path, resulting in large signal refraction and reflection, which affects the signal transmission quality and signal integrity. Summary of the Invention

[0005] In order to overcome the existing shortcomings, the purpose of the present invention is to propose an orthogonal connector that rotates the signal terminal around the Z axis so that the center line of the signal terminal and the center line of the ground terminal are offset by a certain distance in the X direction and the Y direction so that the male end meets the 90-degree or 270-degree orthogonal use requirements.

[0006] The object of the present invention is to achieve the following technical solution. According to the present invention, an orthogonal connector with a rotating structure includes a PCB board 3, and both sides of the PCB board 3 are provided with a mating portion and an inserting portion for use. The mating portions on both sides of the PCB board 3 are arranged orthogonally, and the mating portions are inserted into the PCB board 3 from both sides of the PCB board (3).

[0007] Furthermore, the plug-in portion includes a plurality of terminal modules installed in the insulator seat 11, each terminal module includes a mounting plate, a plurality of signal terminals 6 and a grounding terminal, the signal terminals 6 and the grounding terminals are arranged in a row and fixed by the mounting plate, and a signal terminal differential pair is arranged between two adjacent grounding terminals, and a signal terminal differential pair includes two signal terminals 6.

[0008] Furthermore, the signal terminal 6 includes a signal terminal crimping end and a signal terminal main body extending along the plug-in plane 15. The center line of the signal terminal main body does not coincide with the center line of the signal terminal crimping end. The two signal terminal crimping ends in a signal differential pair rotate in different directions around their corresponding signal terminal main body center lines 606 and offset.

[0009] Furthermore, the crimping ends of the two signal terminals in a signal differential pair are respectively located on two sides of the plug-in plane 15 .

[0010] Furthermore, the crimping end of the signal terminal is a fisheye structure, and a signal terminal fisheye 602 is provided on the fisheye structure. The two signal terminal fisheye lines 13 of a signal differential pair on a terminal module are perpendicular to the two signal terminal fisheye lines 13 of a signal differential pair on an adjacent terminal module, which is used to meet the requirements of the plug-in parts located on both sides of the PCB board 3 to achieve orthogonal connection along the longitudinal axis A.

[0011] Furthermore, the grounding terminal includes a grounding terminal main body extending along the plug-in plane 15 and a grounding terminal crimping part extending along the center line of the grounding terminal main body. The grounding terminal main body and the grounding terminal crimping part are connected through the grounding terminal connecting part, and the grounding terminal crimping end is also a fisheye structure.

[0012] Furthermore, the signal terminal crimping portion and the ground terminal crimping portion in the plug-in portion protrude from the mounting plate from the same side of the mounting plate, and are used to be plugged into and matched with the PCB board 3, and the signal terminal main body and the ground terminal main body protrude from the mounting plate from the other side of the mounting plate, and are used to be plugged into and matched with the corresponding plug-in portion.

[0013] A printed circuit board is provided for plugging and mating with an orthogonal connector with a rotating structure. The printed circuit board is provided with a signal terminal mounting hole 301 and a ground terminal mounting hole 302. The signal terminal mounting hole 301 is used to simultaneously accommodate the signal terminal crimping ends inserted from both sides of the printed circuit board 3, and the two signal terminal crimping ends are in contact and conduction within the same signal terminal mounting hole 301; the ground terminal mounting hole 302 is used to simultaneously accommodate the ground terminal crimping ends inserted from both sides of the printed circuit board 3, and the two ground terminal crimping ends are in contact and conduction within the same ground terminal mounting hole 302.

[0014] Furthermore, the signal terminal mounting holes 301 are combined into a hole pair for accommodating the crimping portion of a signal differential pair of signal terminals, and a hole axis is formed between the two signal terminal mounting holes 301 in a hole pair. The signal terminal mounting holes 301 are arranged in rows and columns, and the hole axis 305 in one column of mounting holes is perpendicular to the hole axis 306 on the adjacent column of mounting holes.

[0015] By means of the above technical solution, the advantages of the present invention are:

[0016] 1. The center line of the signal terminal body does not coincide with the center line of the signal terminal crimping end. The two signal terminal crimping ends in a signal differential pair are rotated in different directions around the center line of their corresponding signal terminal body and offset, which can meet the 90-degree or 270-degree orthogonal use requirements of the first orthogonal male end and the second orthogonal male end.

[0017] 2. The relative misalignment and rotation of the fisheye part of the signal terminal can reduce the refraction and reflection of the signal in the uneven section, reduce the high-frequency signal loss and improve the SI performance.

[0018] 3. The fisheye connection line of the two signal terminals of a signal differential pair on a terminal module is perpendicular to the fisheye connection line of the two signal terminals of a signal differential pair on an adjacent terminal module, so as to ensure that the first orthogonal male terminal and the second orthogonal male terminal located on both sides of the PCB board are orthogonally connected to the plug-in portion along the longitudinal axis A.

[0019] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the following preferred embodiments are specifically cited and described in detail with reference to the accompanying drawings.

[0040] See also Figures 2 to 13 An orthogonal connector with a rotating structure includes a first orthogonal male end 1, a first female end 2, a PCB board 3, a second orthogonal male end 4, and a second female end 5. The first female end 2 is used in conjunction with the first orthogonal male end 1 and is located on one side of the PCB board 3. The second female end 5 is used in conjunction with the second orthogonal male end 3 and is located on the other side of the PCB board 3. The first orthogonal male end 1 and the second orthogonal male end 4 are arranged orthogonally. The first orthogonal male end 1 and the second orthogonal male end 4 are plugged into the PCB board 3 and are in contact and communication with each other through the PCB board 3. An orthogonal connector with a rotating structure also includes a longitudinal axis A, which extends from the first orthogonal male end 1 through the second orthogonal male end 4. Optionally, the first orthogonal male end 1 and the second orthogonal male end 4 can be exactly the same as each other, and the first female end 2 and the second female end 5 can also be exactly the same as each other.

[0041] The first orthogonal male end 1 and the second orthogonal male end 4 are oriented generally in line with each other along the longitudinal axis A, and the first orthogonal male end 1 and the second orthogonal male end 4 are offset relative to each other by 90 degrees or 270 degrees about the longitudinal axis A to form an orthogonal connection therebetween. The first female end 2 and the second female end 5 are also offset relative to each other by 90 degrees or 270 degrees about the longitudinal axis A.

[0042] The orthogonal male terminal includes a plurality of plug-in planes 15, a plurality of signal terminals 6, a ground terminal and an insulator seat 11. The signal terminals 6 and the ground terminal are arranged in the insulator seat 11. The signal terminal 6 includes a signal terminal body 603, a signal terminal connecting portion 605 and a signal terminal fisheye portion 601. The plane formed by the center line 606 of the signal terminal body and the center line of the ground terminal body is the plug-in plane 15. The signal terminal body 603 extends along the plug-in plane 15. The signal terminal fisheye portion 601 is a crimping portion. The signal terminal fisheye portion 60 1 is provided with a signal terminal fisheye 602; a signal terminal connecting portion 605 is located below the terminal main body 603, and the signal terminal fisheye portion 601 is located below the signal terminal connecting portion 605. The signal terminal connecting portion 605 is used to connect the terminal main body 603 and the signal terminal fisheye portion 601; signal terminal limiting portions 604 protruding from the connecting portion 605 are also provided on both sides of the bottom of the signal terminal connecting portion 605. The signal terminal connecting portion 605, the signal terminal fisheye portion 601 and the signal terminal connecting portion 605 are integrally provided.

[0043] like Figure 2 and Figure 5 As shown, the centerline 606 of the signal terminal body and the centerline 607 of the signal terminal fisheye do not coincide with each other. An XYZ coordinate system is established. The signal terminal connection portion 605 rotates around the centerline 606 of the signal terminal body by a certain angle. Under the action of the signal terminal connection portion 605, the signal terminal fisheye portion 601 also rotates around the centerline 606 of the signal terminal body. After the rotation, the position of the signal terminal fisheye portion 601 also changes. That is, the signal terminal fisheye portion 601 is offset by a certain distance in the X and Y directions. The signal terminal connection portion 605 and the signal terminal fisheye portion 601 are relatively misaligned. The relative misalignment and rotation of the signal terminal connection portion 605 and the signal terminal fisheye portion 601 can reduce the refraction and reflection of the signal in the uneven section, reduce the high-frequency signal loss, and improve the SI performance. Please refer to Figure 5 Two adjacent signal terminals 6 form a signal differential pair. The two signal terminal fisheye portions 601 in a differential pair rotate in different directions around the center line 606 of the corresponding signal terminal body portion. That is, the positions of the two signal terminal fisheye portions 601 in a signal differential pair change differently after rotation, resulting in misalignment. One signal terminal fisheye portion 601 in a differential pair is offset toward one side of the plugging plane 15, and the other signal terminal fisheye portion 601 is offset toward the other side of the plugging plane 15. That is, the two signal terminal fisheye portions 601 in a differential pair are located on both sides of the plugging plane 15. In addition, the two signal terminal fisheye portions 601 in a signal differential pair are closer to each other after rotation, which can increase coupling. Please refer to Figure 2 and Figure 3The grounding terminal includes a first grounding terminal 7 and a second grounding terminal 8, wherein the first grounding terminal 7 includes a first grounding terminal main body 703 extending along the plug-in plane 15, a first grounding terminal connecting portion 705 extending along the center line 708 of the first grounding terminal main body, and a first grounding terminal fisheye portion 701. The first grounding terminal fisheye portion 701 is a crimping portion, and a first grounding terminal fisheye 704 is provided on the first grounding terminal fisheye portion 701. The first grounding terminal connecting portion 705 is located below the first grounding terminal main body 703, and the first grounding terminal fisheye portion 701 is located below the first grounding terminal connecting portion 705. The first grounding terminal main body 703, the first grounding terminal connecting portion 705, and the first grounding terminal fisheye portion 701 are integrally arranged. In addition, a first grounding terminal limiting portion 702 is also provided on one side of the bottom of the first grounding terminal connecting portion 705. Please refer to Figure 2 The first grounding terminal body 703 and the first grounding terminal eye 701 are located in the same plane, but the centerline 708 of the first grounding terminal body and the centerline 709 of the first grounding terminal eye do not overlap. The second grounding terminal 8 includes a second grounding terminal body 803 extending along the insertion plane 15, a second grounding terminal connection portion 805, and a second grounding terminal eye 802. The second grounding terminal connection portion 805 is connected to the second grounding terminal body 803 at one end and to the second grounding terminal eye 802 at the other end. Each second grounding terminal eye 802 is provided with a second grounding terminal eye 804. The second grounding terminal connection portion 805 and the second grounding terminal eye 802 are integrally provided and located in the same plane. A second grounding terminal stopper 801 is also provided on the bottom side of the second grounding terminal connection portion 805. In this embodiment, two second grounding terminal eye 802 are provided. In other embodiments of the present invention, the number of second grounding terminal eye 802 can be adjusted based on usage needs.

[0044] See also Figures 7 to 10 The signal terminals 6 and the ground terminals are punched in a row, and then the signal terminals 6 and the ground terminals are punched in a row and then injection molded into wafers. The wafers include waferA9 and waferB10. WaferA9 and waferB10 have similar structures and components, except that there is a certain misalignment between the signal terminals 6 on waferA9 and waferB10. Figure 10 As shown, each wafer includes plastic 12, multiple signal terminals 6, and ground terminals. When processing the wafer, multiple signal terminals 6 and ground terminals are injection molded together using an integral injection molding method to form a wafer, and the signal terminals 6 and ground terminals are distributed in the plastic 12; the signal terminal fisheye portion 602 and the signal terminal body portion 603 protrude from the plastic 12, and the ground terminal fisheye portion and the ground terminal body portion also protrude from the plastic 12. Figure 9As shown, one end of the terminals in a row on each wafer is a first ground terminal 7, the other end is a second ground terminal 8, and multiple second ground terminals 8 and signal terminals 6 are arranged in the middle. Two adjacent signal terminals 3 form a differential pair, and the differential pair is arranged between the two ground terminals.

[0045] like Figure 7 As shown in FIG8 , a plurality of waferA9 and waferB10 are arranged in parallel in the insulator seat 11 to form a connector. The waferA9 and waferB10 in the insulator seat 11 are arranged in an alternating manner. Figure 8b As shown, the upper ends of the two side walls of the insulator seat 11 are correspondingly provided with multiple grooves. The ends of the plastic 12 on the wafer enter the grooves and form an interference fit with the grooves, thereby fixing the wafer in the insulator seat 11. After wafer A9 and wafer B10 are installed in the insulator seat 11, the signal terminal fisheye portion 602 and the ground terminal fisheye portion on wafer A9 and wafer B10 protrude from the insulator seat 11 for insertion into the PCB board 3. Figure 8c and Figure 11 , viewed from the mating end with the female end, the signal terminal body 603 and the ground terminal body are located on the same horizontal line and are mated with the corresponding female end.

[0046] See also Figure 8a The fisheye connection line 13 between the two signal terminals in a differential pair on waferA9 is perpendicular to the fisheye connection line 13 between the two signal terminals in a differential pair on the adjacent waferB10. Figure 5 The top view of the plug-in plane 15 coincides with the ground terminal fisheye connection 14. The two signal terminal fisheye connections 13 in a differential pair are at a 45-degree angle to the ground terminal fisheye connection 14 and the direction perpendicular to the ground terminal fisheye connection 14, which can meet the 90-degree or 270-degree orthogonal use requirements of the first orthogonal male terminal 1 and the second orthogonal male terminal 4.

[0047] See also Figure 13The PCB 3 is provided with multiple signal terminal mounting holes 301 and ground terminal mounting holes 302. Each signal terminal mounting hole 301 can accommodate two signal terminal fisheye portions 601 inserted into the hole from either side of the PCB 3, and each ground terminal mounting hole 302 can accommodate two ground terminal fisheye portions inserted into the hole from either side of the PCB 3. The signal terminal mounting holes 301 and the ground terminal mounting holes 302 correspond to the signal terminals 6 and the ground terminals within the orthogonal male terminal. In this embodiment, the signal terminal mounting holes 301 and the ground terminal mounting holes 302 are through holes. In other embodiments of the present invention, they may also be other types of holes, such as blind holes. Signal terminal mounting holes 301 and ground terminal mounting holes 302 are arranged in rows and columns. Adjacent signal terminal mounting holes 301 in each column form a wafer differential pair hole pair, which is used to insert the fisheye portion of the signal terminal differential pair. A hole axis is formed between the two signal terminal mounting holes 301 in the wafer differential pair hole pair. The wafer differential pair hole pair includes wafer A hole pair 303 and wafer B hole pair 304. A wafer A hole axis 305 is formed between the two signal terminal mounting holes 301 in wafer A hole pair, and a wafer B hole axis 306 is formed between the two signal terminal mounting holes 301 in wafer B hole pair. The angle β formed between the hole axis 305 in one column of mounting holes and the hole axis 306 in the adjacent column is 90 degrees, meaning that the wafer A hole axis 305 is perpendicular to the wafer B hole axis 306.

[0048] See also Figure 6 and Figure 13 The second orthogonal male terminal 4 is arranged at a 90-degree or 270-degree angle to the first orthogonal male terminal 1. After the orthogonality is achieved, the second orthogonal male terminal 4 and the portion of the signal terminals 6 in the first orthogonal male terminal 1 are inserted into the same signal terminal mounting hole 301. The second orthogonal male terminal 4 and the portion of the grounding terminals in the first orthogonal male terminal 1 are inserted into the same grounding terminal mounting hole 302. The specific process of inserting the first orthogonal male terminal 1 and the portion of the second orthogonal male terminal 4 into the same hole position of the printed circuit board 3 from both sides is as follows. Figure 14Taking a signal differential pair on the first orthogonal male terminal 1 and a corresponding signal differential pair on the second orthogonal male terminal 4 as an example, the signal terminal fisheye portion 602 of the signal differential pair on the first orthogonal male terminal 1 is inserted into the signal terminal mounting holes 301 of the wafer differential pair hole pair from one side of the PCB board 3. Because the two signal terminal fisheye connection lines 13 of the signal differential pair on one wafer are perpendicular to the two signal terminal fisheye connection lines 13 of the signal differential pair on the adjacent wafer, the orthogonality requirement of the first orthogonal male terminal 1 and the second orthogonal male terminal 4 can be met. Therefore, when the second orthogonal male terminal 4, which is orthogonal to the first orthogonal male terminal 1, is inserted into the PCB board 3 from the other side of the PCB board 3, the signal terminal fisheye portions 602 of the signal differential pair corresponding to the signal differential pair on the first orthogonal male terminal 1 are inserted into the same two signal terminal mounting holes 301 from the other side of the PCB board 3. The signal terminal fisheye portions 602 inserted into the same signal terminal mounting holes 301 make contact and conduction. Similarly, the grounding terminal fisheye portion on the first orthogonal male terminal 1 is inserted into the grounding terminal mounting hole 302 from one side of the PCB board 3, and the grounding terminal fisheye portion on the second orthogonal male terminal 4 is inserted into the same grounding terminal mounting hole 302 from the other side of the PCB board 3. The grounding terminal fisheye portions located in the same grounding terminal mounting hole 302 come into contact, thereby establishing electrical conduction between the two grounding terminals. The contact between the signal terminals and the ground terminals establishes connectivity between the orthogonal second orthogonal male terminal 4 and the first orthogonal male terminal 1, allowing signals to be transmitted from the first female terminal 2 and the first orthogonal male terminal 1 to the second orthogonal male terminal 4 and the second female terminal 5, or vice versa.

[0049] The above is only a preferred embodiment of the present invention. Any simple modification, equivalent change and modification made to the above embodiment by any technician familiar with this profession based on the technical essence of the present invention without departing from the scope of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
