Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a terminal mating structure and a high-speed backplane connector assembly. Background Technology

[0002] In existing technologies, backplane connector assemblies are typically required to achieve high-speed signal transmission. A backplane connector assembly generally includes mating male and female connectors, each containing several terminal assemblies, and each terminal assembly includes several terminals. After the male and female connectors are plugged in, the terminals of the male and female connectors connect together, thus enabling signal transmission. If the connection between the terminals of the male and female connectors is poor, it will lead to unstable signal transmission or even a complete failure to transmit signals. However, in existing technologies, it is difficult to guarantee both an effective and stable connection between the terminals of the male and female connectors and to achieve high-speed signal transmission. Summary of the Invention

[0003] Based on this, the present invention provides a terminal mating structure, comprising: two mating terminals, each terminal comprising a lever arm, the lever arm comprising an abutting portion, a connecting segment, and an abutting segment arranged sequentially along its length direction; when the two terminals are mated, the abutting portion of each terminal abuts against the abutting segment of the mating terminal, and the connecting segments of the two terminals are arranged facing each other; one side surface of the connecting segments of the two terminals facing each other is constructed as a first mating surface; a second mating surface is formed on the first mating surface that is recessed inward relative to the first mating surface or coincides with the first mating surface; when the two terminals are mated, the second mating surfaces of the lever arms of the two terminals are arranged facing each other and the distance between them is greater than the distance between the first mating surfaces of the lever arms of the two terminals.

[0004] Furthermore, the first mating surfaces of the two terminal levers are parallel to each other, and the distance between the first mating surfaces of the two terminal levers is 0.1 to 0.5 mm.

[0005] Furthermore, the distance between the second mating surfaces of the two terminal lever arms is 0.3 to 1.5 mm.

[0006] Furthermore, the width of the second mating surface is smaller than the width of the abutting portion, and the width of the second mating surface is smaller than the width of the first mating surface.

[0007] Preferably, each lever arm has a second mating surface; the second mating surface is located on one side of the width direction of the first mating surface, or the second mating surface is located in the middle of the width direction of the first mating surface.

[0008] Furthermore, the lever arm also includes an inlet section, which is connected to the connecting section, and the connection between the two is bent to form the abutment portion.

[0009] Preferably, the length of the inlet segment is 0.5 to 0.95 mm.

[0010] Preferably, a reinforcing structure is provided at the connection between the inlet segment and the connecting segment, and the reinforcing structure extends inward toward the bend at the connection between the inlet segment and the connecting segment.

[0011] The present invention also provides a high-speed backplane connector assembly, comprising: a male connector and a female connector that cooperate with each other; wherein, the male connector and the female connector each include a plastic base and a plurality of terminal assemblies stacked and fixed within the plastic base, the terminal assemblies of the male connector and the terminal assemblies of the female connector are correspondingly fitted, each terminal assembly includes an insulating base and a plurality of terminals, the terminals of the terminal assemblies of the male connector and the terminals of the terminal assemblies of the female connector are correspondingly fitted to form the terminal fitting structure as described above, the plurality of terminals of each terminal assembly are fixedly spaced within the insulating base of the terminal assembly along the width direction of the terminals, and the lever arm of each terminal extends outside the insulating base, wherein the abutting portion is located at the free end of the lever arm, and the abutting section is located at the fixed end of the lever arm.

[0012] Furthermore, the multiple terminals are connected in sequence to form a terminal block by means of material strips. The terminal block is integrally formed with the insulating seat as an insert through in-mold injection molding. After integral forming, the material strip is located outside the insulating seat, and the insulating seat has cutting and positioning grooves that correspond one-to-one with the material strips.

[0013] Furthermore, the abutting section of the lever arm has abutting surface and non-abutting surface arranged opposite to each other, wherein the abutting surface is connected to the first mating surface, and the insulating base has a boss corresponding to the root of the abutting section of the lever arm, and each boss abuts against the non-abutting surface of the root of the corresponding abutting section of the lever arm.

[0014] Furthermore, the terminals are divided into grounding terminals and signal terminals, and the grounding terminals and signal terminals in each terminal assembly are alternately arranged. At least two hollowed-out portions are provided on the lever arm abutment section of each grounding terminal.

[0015] Preferably, each of the terminal assemblies further includes a shielding sheet, which is fixed to the insulating base and electrically connected to each of the grounding terminals.

[0016] Compared with the prior art, the beneficial features of the present invention are as follows: When the two terminals mate, the abutting portion of each terminal abuts against the abutting section of the mating terminal, resulting in a more reliable abutment and preventing the two mating terminals from disconnecting, thus ensuring a stable and effective connection between the two mating terminals. Moreover, when the two terminals mate, the second mating surfaces of the two terminal arms face each other, and the distance between them is greater than the distance between the first mating surfaces of the two terminal arms. This does not affect the effective abutment between the terminal arms and the mating terminal arms, ensuring a stable and effective connection between the two mating terminals, while also achieving a higher signal transmission speed. This avoids the situation where increasing the distance between the first mating surfaces of the two terminal arms to improve signal transmission speed would result in an inability to guarantee effective abutment between the two terminal arms.

Detailed Implementation

[0042] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0043] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0044] 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 in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0045] In this embodiment of the invention, the X, Y, and Z directions are perpendicular to each other.

[0046] Please refer to Figure 1 , Figures 3 to 19 ,and Figures 21 to 24The terminal mating structure of this invention includes a male terminal 1a and a female terminal 1b that mate with each other. Both the male terminal 1a and the female terminal 1b include a lever arm 101, which extends along the X direction. The lever arm 101 includes an abutment portion 1011, a connecting section 1012, and an abutment section 1013 arranged sequentially along its length. In use, the male terminal 1a and the female terminal 1b must be mated together. Figures 3 to 8As shown, to ensure a secure connection and prevent the male terminal 1a and female terminal 1b from disconnecting, when the male terminal 1a and female terminal 1b are inserted into place, the abutting portion 1011 of the male terminal 1a abuts against the abutting section 1013 of the female terminal 1b, and the abutting portion 1011 of the female terminal 1b abuts against the abutting section 1013 of the male terminal 1a. Furthermore, the connecting section 1012 of the male terminal 1a and the connecting section 1012 of the female terminal 1b face each other. The surface of the connecting section 1012 of the male terminal 1a and the connecting section 1012 of the female terminal 1b facing each other is constructed as the first mating surface 10121 of the lever arm 101 of the male terminal 1a, and the surface of the connecting section 1012 of the female terminal 1b and the connecting section 1012 of the male terminal 1a facing each other is constructed as the first mating surface 10121 of the lever arm 101 of the female terminal 1b. Because an excessively large gap between the first mating surface 10121 of the male terminal 1a lever arm 101 and the first mating surface 10121 of the female terminal 1b lever arm 101 would prevent effective contact between them, while an excessively small gap would fail to meet high-speed transmission requirements. Therefore, to address this issue, a second mating surface 10122 is formed on the first mating surface 10121 of the male terminal 1a lever arm 101, either recessed inwards from or overlapping with the first mating surface 10121 of the male terminal 1a lever arm 101. A second mating surface 10122 is formed on the first mating surface 10121 of the female terminal 1b lever arm 101. There is a first mating surface 10121 of the male terminal 1b lever arm 101 that is recessed into the female terminal 1b lever arm 101 or overlaps with the first mating surface 10121 of the female terminal 1b lever arm 101. When the male terminal 1a and the female terminal 1b are mated, the second mating surface 10122 of the male terminal 1a lever arm 101 and the second mating surface 10122 of the female terminal 1b lever arm 101 are arranged facing each other, and the distance between the second mating surface 10122 of the male terminal 1a lever arm 101 and the second mating surface 10122 of the female terminal 1b lever arm 101 is greater than the distance between the first mating surface 10121 of the male terminal 1a lever arm 101 and the first mating surface 10121 of the female terminal 1b lever arm 101. This does not affect the effective contact between the male terminal 1a lever arm 101 and the female terminal 1b lever arm 101, while also achieving a higher signal transmission speed.

[0047] In some preferred embodiments, to ensure that the abutting portion 1011 of the male terminal 1a can effectively abut against the abutting section 1013 of the female terminal 1b, and at the same time ensure that the abutting portion 1011 of the female terminal 1b can effectively abut against the abutting section 1013 of the male terminal 1a, the first mating surface 10121 of the lever arm 101 of the male terminal 1a and the first mating surface 10121 of the lever arm 101 of the female terminal 1b are parallel to each other, such as... Figures 4 to 8 As shown.

[0048] In some preferred embodiments, to ensure that the abutting portion 1011 of the male terminal 1a can effectively abut with the abutting section 1013 of the female terminal 1b, and simultaneously ensure that the abutting portion 1011 of the female terminal 1b can effectively abut with the abutting section 1013 of the male terminal 1a, and to ensure that the male terminal 1a and the female terminal 1b can be easily inserted into place without damaging the lever arm 101 during insertion, the distance D1 between the first mating surface 10121 of the lever arm 101 of the male terminal 1a and the first mating surface 10121 of the lever arm 101 of the female terminal 1b is 0.1 to 0.5 mm. When the distance between the first mating surface 10121 of the lever arm 101 of the male terminal 1a and the first mating surface 10121 of the lever arm 101 of the female terminal 1b is less than 0.1 mm, it is difficult to insert the male terminal 1a and the female terminal 1b together, and the lever arm 101 may be damaged during the insertion process. When the distance between the first mating surface 10121 of the male terminal 1a lever arm 101 and the first mating surface 10121 of the female terminal 1b lever arm 101 is greater than 0.5mm, it may result in the inability to guarantee that the male terminal 1a lever arm 101 and the female terminal 1b lever arm 101 can effectively abut, and there is a possibility that the male terminal 1a lever arm 101 and the female terminal 1b lever arm 101 will be disconnected or have abnormal contact.

[0049] In some preferred embodiments, the distance D2 between the second mating surface 10122 of the male terminal 1a lever arm 101 and the second mating surface 10122 of the female terminal 1b lever arm 101 is 0.3 to 1.5 mm, which can at least meet the requirements of high-speed 56G transmission.

[0050] In some preferred embodiments, to avoid an excessive difference in strength between the lever arm 101 of the male terminal 1a and the lever arm 101 of the female terminal 1b, please refer to... Figure 5 and Figure 6 The second mating surface 10122 of the male terminal 1a lever arm 101 is recessed inward relative to the first mating surface 10121 of the male terminal 1a lever arm 101, and the second mating surface 10122 of the female terminal 1b lever arm 101 is recessed inward relative to the first mating surface 10121 of the female terminal 1b lever arm 101.

[0051] More preferably, to further avoid an excessive difference in strength between the lever arm 101 of the male terminal 1a and the lever arm 101 of the female terminal 1b, please refer to... Figure 5 and Figure 6 The distance D3 between the second mating surface 10122 of the male terminal 1a lever arm 101 and the first mating surface 10121 of the male terminal 1a lever arm 101 is equal to the distance D4 between the second mating surface 10122 of the female terminal 1b lever arm 101 and the first mating surface 10121 of the female terminal 1b lever arm 101. Accordingly, in order to at least meet the requirements of high-speed 56G transmission, the distance D3 between the second mating surface 10122 of the male terminal 1a lever arm 101 and the first mating surface 10121 of the male terminal 1a lever arm 101 is 0.1 to 0.5 mm, the distance D4 between the second mating surface 10122 of the female terminal 1b lever arm 101 and the first mating surface 10121 of the female terminal 1b lever arm 101 is 0.1 to 0.5 mm, and the distance D2 between the second mating surface 10122 of the male terminal 1a lever arm 101 and the second mating surface 10122 of the female terminal 1b lever arm 101 is 0.3 to 1.5 mm.

[0052] In other preferred embodiments, for ease of manufacture and structural simplification, please refer to... Figure 7 and Figure 8 In the mating male terminal 1a and female terminal 1b, only the second mating surface 10122 of one terminal arm 101 is recessed inward relative to the first mating surface 10121 of the terminal arm 101. The second mating surface 10122 of the other terminal arm 101 coincides with the first mating surface 10121 of the terminal arm 101.

[0053] In some specific implementation methods, such as Figure 7 As shown, the second mating surface 10122 of the female terminal 1b lever arm 101 is recessed inward relative to the first mating surface 10121 of the female terminal 1b lever arm 101. The second mating surface 10122 of the male terminal 1a lever arm 101 coincides with the first mating surface 10121 of the male terminal 1a lever arm 101, that is, the distance D3 between the second mating surface 10122 and the first mating surface 10121 of the male terminal 1a lever arm 101 is 0. Accordingly, in order to at least meet the requirements of high-speed 56G transmission, the distance D4 between the second mating surface 10122 of the female terminal 1b lever arm 101 and the first mating surface 10121 of the female terminal 1b lever arm 101 is 0.2 to 1.0 mm, and the distance D2 between the second mating surface 10122 of the male terminal 1a lever arm 101 and the second mating surface 10122 of the female terminal 1b lever arm 101 is 0.3 to 1.5 mm.

[0054] In some specific implementation methods, such as Figure 8 As shown, the second mating surface 10122 of the male terminal 1a lever arm 101 is recessed inward relative to the first mating surface 10121 of the male terminal 1a lever arm 101. The second mating surface 10122 of the female terminal 1b lever arm 101 coincides with the first mating surface 10121 of the female terminal 1b lever arm 101, that is, the distance D4 between the second mating surface 10122 of the female terminal 1b lever arm 101 and the first mating surface 10121 of the female terminal 1b lever arm 101 is 0. Accordingly, in order to at least meet the requirements of high-speed 56G transmission, the distance D3 between the second mating surface 10122 of the male terminal 1a lever arm 101 and the first mating surface 10121 of the male terminal 1a lever arm 101 is 0.2 to 1.0 mm, and the distance D2 between the second mating surface 10122 of the male terminal 1a lever arm 101 and the second mating surface 10122 of the female terminal 1b lever arm 101 is 0.3 to 1.5 mm.

[0055] In other embodiments, the distance D3 between the second mating surface 10122 of the male terminal 1a arm 101 and the first mating surface 10121 of the male terminal 1a arm 101 is not equal to the distance D4 between the second mating surface 10122 of the female terminal 1b arm 101 and the first mating surface 10121 of the female terminal 1b arm 101, and the distance D3 between the second mating surface 10122 of the male terminal 1a arm 101 and the first mating surface 10121 of the male terminal 1a arm 101 is greater than 0, and the distance D4 between the second mating surface 10122 of the female terminal 1b arm 101 and the first mating surface 10121 of the female terminal 1b arm 101 is greater than 0. Accordingly, in order to at least meet the requirements of high-speed 56G transmission, the distance D2 between the second mating surface 10122 of the male terminal 1a arm 101 and the second mating surface 10122 of the female terminal 1b arm 101 is 0.3 to 1.5 mm.

[0056] In some preferred embodiments, please refer to Figures 3 to 19 , Figures 21 to 24 To avoid affecting the strength of lever arm 101, when the second mating surface 10122 of lever arm 101 is recessed inward relative to the first mating surface 10121 of lever arm 101, a convex 10123 is provided on lever arm 101. The convex 10123 has a concave surface and a convex surface that are arranged opposite to each other. The convex surface protrudes outward relative to lever arm 101, and the concave surface is recessed inward relative to lever arm 101. The concave surface of the convex 10123 is the second mating surface 10122.

[0057] In other embodiments, when the second mating surface 10122 of the lever arm 101 is recessed inward relative to the first mating surface 10121 of the lever arm 101, only a portion of the upper region of the first mating surface 10121 of the lever arm 101 is thinned along the Y direction to form the second mating surface 10122. That is, only the second mating surface 10122 is recessed inward relative to the first mating surface 10121 of the lever arm 101, and the aforementioned convex bulge 10123 is not formed.

[0058] In some preferred embodiments, please refer to Figure 3 , Figures 9 to 13 , Figures 16 to 17 , Figure 19 ,and Figures 21 to 24 To prevent the abutment portion 1011 from falling into the second mating surface 10122 during insertion and affecting the connection, the width W2 of the second mating surface 10122 is smaller than the width W3 of the abutment portion 1011, that is, the length of the second mating surface 10122 in the Z direction is smaller than the length of the abutment portion 1011 in the Z direction. Correspondingly, when the second mating surface 10122 is the concave surface of the convex hull 10123, if the recess of the convex hull 10123 has a chamfered structure 10124, then the width W2 of the second mating surface 10122 should include the width of the chamfered structure 10124. Figure 17 As shown.

[0059] In some preferred embodiments, please refer to Figure 3 , Figures 9 to 13 , Figures 16 to 17 , Figure 19 ,and Figures 21 to 24 To avoid excessively affecting the strength of the influence arm 101, the width W2 of the second mating surface 10122 is smaller than the width W1 of the first mating surface 10121, that is, the length of the second mating surface 10122 in the Z direction is smaller than the length of the first mating surface 10121 in the Z direction. Correspondingly, when the second mating surface 10122 is the concave surface of the convex hull 10123, if the concave area of ​​the convex hull 10123 has a chamfered structure 10124, then the width W2 of the second mating surface 10122 should include the width of the chamfered structure 10124. Figure 17 As shown.

[0060] In some preferred embodiments, to simplify the structure, each lever arm 101 has a second mating surface 10122. In a specific embodiment, please refer to... Figure 1 , Figures 9 to 15 , Figure 19 , Figure 21 ,and Figures 23 to 24The second mating surface 10122 is located on one side of the first mating surface 10121 in the width direction, that is, in the Z direction, the second mating surface 10122 is located on one side of the first mating surface 10121. In another specific embodiment, please refer to... Figures 3 to 8 , Figures 16 to 18 ,and Figure 22 The second mating surface 10122 is located in the middle of the width direction of the first mating surface 10121, that is, in the Z direction, the second mating surface 10122 is located in the middle of the first mating surface 10121.

[0061] In summary, during the insertion process of male terminal 1a and female terminal 1b, a portion of the contact portion 1011 of both parties can always pass over the first mating surface 10121 of the corresponding terminal, and there will be no pin jamming phenomenon with the concave surface (i.e., the recess, the second mating surface 10122) formed by the protrusion 10123, thus ensuring the smooth insertion process of male terminal 1a and female terminal 1b.

[0062] In other embodiments, each lever arm 101 may also have at least two second mating surfaces 10122. The second mating surfaces 10122 are arranged at intervals along the X direction, at intervals along the Y direction, or in other forms, as long as the high-speed transmission requirements are met. The second mating surfaces 10122 of the male terminal 1a lever arm 101 and the corresponding female terminal 1b lever arm 101 are provided in a one-to-one correspondence. The distance between the second mating surface 10122 on the same lever arm 101 and the first mating surface 10121 of the same lever arm 101 may be different or the same, as long as the distance D2 between the second mating surface 10122 of the male terminal 1a lever arm 101 and the corresponding second mating surfaces 10122 on the corresponding female terminal 1b lever arm 101 can ensure that the high-speed transmission requirements are met.

[0063] In some preferred embodiments, please refer to Figures 3 to 19 ,and Figures 21 to 24 To facilitate insertion, lever arm 101 also includes an inlet section 1014, which is connected to connecting section 1012. The connection between inlet section 1014 and connecting section 1012 is bent to form a contact portion 1013. The contact portion 1013 makes the contact between male terminal 1a lever arm 101 and female terminal 1b lever arm 101 more secure.

[0064] In some preferred embodiments, please refer to Figure 14 To prevent pin failure while ensuring easy insertion and assembly of male terminal 1a and female terminal 1b, the length L of the guide section 1014 is 0.5–0.95 mm. When the length L of the guide section 1014 is less than 0.5 mm, pin failure is likely. When the length L of the guide section 1014 is greater than 0.95 mm, insertion and assembly are difficult.

The abutting surface 10131 is connected to the first mating surface 10121 and is used to abut and engage with the abutting portion 1011 of the female terminal 1b. The male terminal insulating base 2a has a boss 202 corresponding to the root of the abutting section 1013 of the lever arm 101 of the male terminal 1a. Each boss 202 abuts against the non-abutting surface 10132 of the root of the abutting section 1013 of the corresponding male terminal 1a lever arm 101. That is, the boss 202 abuts against the side of the male terminal 1a lever arm 101 away from the abutting female terminal 1b. After the male terminal 1a and the female terminal 1b are inserted, the boss 202 can act as a fulcrum to support the corresponding male terminal 1a lever arm 101, avoiding fatigue of the male terminal 1a after the male terminal 1a and the female terminal 1b are inserted. In the female terminal assembly, the abutting section 1013 of the lever arm 101 has an abutting surface 10131 and a non-abutting surface 10132 that are arranged opposite to each other. The abutment surface 10131 is connected to the first mating surface 10121, and the abutment surface 10131 is used to abut and engage with the abutment portion 1011 of the male terminal 1a. The female end insulating base 2b has a boss 202 corresponding to the root of the abutment section 1013 of the lever arm 101 of the female end terminal 1b. Each boss 202 abuts against the non-abutment surface 10132 of the root of the abutment section 1013 of the corresponding female end terminal 1b lever arm 101. That is, the boss 202 abuts against the side of the female end terminal 1b lever arm 101 away from the abutting male end terminal 1a. After the male end terminal 1a and the female end terminal 1b are inserted, the boss 202 can act as a fulcrum to support the corresponding female end terminal 1b lever arm 101, avoiding fatigue of the female end terminal 1b after the male end terminal 1a and the female end terminal 1b are inserted.

When the male terminal assembly and the female terminal assembly are mated, the cutouts 10133 not only facilitate the elastic deformation of the grounding terminal 10 and make it easier to insert, but also enable the connector to meet the requirements of high-speed 60G transmission.

[0072] In some specific embodiments, the cutout 10133 is an elongated hole extending along the X direction, i.e., along the length of the lever arm 101. In other embodiments, the cutout 10133 can also be other forms of cutout structure, such as uniformly distributed holes, etc., as long as the connector can meet the requirements of high-speed 60G transmission, the effect of this embodiment can be achieved.
