[0002] In existing server architectures, high-density connectors are used to connect different electronic components, especially when establishing electrical connections between the motherboard and expansion cards, memory modules, etc. These connectors typically have a large number of terminals, enabling them to carry high-speed data transmission and current.

[0003] However, existing high-density connectors require operators to apply significant force to insert and remove them. This not only increases the difficulty of operation for workers, but also causes the PCB board around the high-density connector to bend and deform during frequent insertion and removal. Utility Model Content

[0004] This application provides a high-density connector and a server having the same, to at least solve the problem in the related art that the insertion and removal of high-density connectors increases the labor intensity of workers.

[0005] This application provides a high-density connector, including: a first connecting terminal; a second connecting terminal disposed opposite to the first connecting terminal; and a connecting assembly, wherein the first connecting terminal is connected to the second connecting terminal through the connecting assembly, the connecting assembly including a fastener and a mating recess, wherein at least a portion of the fastener extends into the mating recess and is threadedly connected to the mating recess.

[0006] Furthermore, there is one connecting component located in the middle of the first connecting terminal and / or the second connecting terminal; or, there are multiple connecting components, which are spaced apart along the length and / or width of the high-density connector.

[0007] Furthermore, the high-density connector also includes a mating component, which includes: a first mating part disposed on the first connecting terminal; and a second mating part disposed on the second connecting terminal; wherein, one of the first mating part and the second mating part is a protrusion, and the other of the first mating part and the second mating part is a first limiting recess, and the protrusion extends into the first limiting recess and is limited and mated with the first limiting recess.

[0008] Furthermore, the first mating part is a protrusion, and the fastener passes through the protrusion; the second mating part is a first limiting recess, and the first limiting recess communicates with the mating recess.

[0009] Furthermore, the protrusion has a second limiting recess, and a limiting protrusion is provided on the outer peripheral surface of the fastener. The limiting protrusion extends into the second limiting recess and engages with the second limiting recess to limit the fastener axially.

[0010] Further, the first connecting terminal includes: a first plate body; a first terminal portion, with the protrusion and the first terminal portion spaced apart on the plate surface of the first plate body; wherein, the protrusion includes a second plate body and a surrounding plate, the second plate body is disposed opposite to the first plate body, and the second plate body is connected to the first plate body through the surrounding plate; at least a portion of the first plate body, the surrounding plate, and the second plate body surround to form a second limiting recess, the second plate body has a first through hole, and at least a portion of the fastener passes through the first through hole and is threadedly connected to the mating recess.

[0011] Furthermore, the first plate has a second through hole communicating with the second limiting recess, and the fastener includes: a column, with a limiting protrusion disposed on the outer surface of the column; wherein, the first end of the column passes through the second through hole, and the second end of the column passes through the first through hole and is threadedly connected to the mating recess.

[0012] Furthermore, the second connecting terminal includes: a third plate; a connecting platform; and a second terminal portion, wherein the connecting platform and the second terminal portion are spaced apart on the plate surface of the third plate; wherein the height of the connecting platform is lower than the height of the second terminal portion, so that a first limiting recess is formed between the connecting platform and the second terminal portion; the mating recess extends from the platform surface of the connecting platform toward the third plate.

[0013] Furthermore, the mating recess is an internally threaded hole; and / or, the connecting platform has an annular hole surrounding the mating recess.

[0014] This application also provides a server, including the aforementioned high-density connector.

[0015] By applying the technical solution of this application, the threaded connection between the fastener and the mating recess transforms the large insertion and extraction force originally required in the linear direction into the torque needed to rotate the fastener. This effectively reduces the force required to connect and disconnect high-density connectors, significantly improving operational convenience and efficiency, and solving the problem of increased labor intensity for workers during the insertion and extraction of high-density connectors in related technologies. Specifically, when connecting the first and second connecting terminals, the fastener is aligned with the mating recess, and by screwing in the fastener, the first and second connecting terminals gradually engage to achieve electrical connection. Because the screwing-in process of the fastener provides a uniform and stable force, the required insertion force is significantly reduced compared to the traditional direct insertion and extraction method. When separating the first and second connecting terminals, the fastener is unscrewed, and the first and second connecting terminals can separate due to their own structural characteristics or slight external force, again saving extraction force. Simultaneously, because the above process reduces insertion and extraction force, it also reduces the risk of accidental damage to the circuit boards or other electronic components surrounding the high-density connector during insertion or extraction, helping to extend the service life of electronic equipment and improve system reliability.

[0031] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] To address the issue that the insertion and removal of high-density connectors in related technologies increases the labor intensity of workers, this application provides a high-density connector and a server having the same.

[0033] like Figures 1 to 6As shown, this application provides a high-density connector, including a first connecting terminal 10, a second connecting terminal 20, and a connecting assembly 30. The second connecting terminal 20 is disposed opposite to the first connecting terminal 10. The first connecting terminal 10 is connected to the second connecting terminal 20 via the connecting assembly 30. The connecting assembly 30 includes a fastener 31 and a mating recess 32. At least a portion of the fastener 31 extends into the mating recess 32 and is threadedly connected to the mating recess 32.

[0034] By applying the technical solution of this embodiment, the threaded connection between the fastener 31 and the mating recess 32 transforms the large insertion and extraction force originally required in the linear direction into the torque required to rotate the fastener 31. This effectively reduces the force required to connect and disconnect high-density connectors, significantly improving operational convenience and efficiency, and solving the problem of increased labor intensity for workers when inserting and removing high-density connectors in related technologies. Specifically, when connecting the first connecting terminal 10 and the second connecting terminal 20, the fastener 31 is aligned with the mating recess 32, and the first connecting terminal 10 and the second connecting terminal 20 are gradually engaged by screwing in the fastener 31 to achieve electrical connection. Since the screwing process of the fastener 31 provides a uniform and stable force, the required insertion force is significantly reduced compared to the traditional direct insertion and extraction method. When separating the first connecting terminal 10 and the second connecting terminal 20, the fastener 31 is unscrewed, and the first connecting terminal 10 and the second connecting terminal 20 can be separated by their own structural characteristics or under slight external force, thus saving extraction force as well. At the same time, since the above process reduces the insertion and extraction force, it also reduces the risk of accidental damage to the circuit boards or other electronic components around the high-density connector during insertion or extraction, which helps to extend the service life of electronic devices and improve the reliability of the system.

[0035] Optionally, the connecting component 30 is a single component located in the middle of the first connecting terminal 10 and / or the second connecting terminal 20; alternatively, there are multiple connecting components 30, spaced apart along the length and / or width of the high-density connector. This ensures a uniform distribution of connection force when the connecting component 30 is located in the middle, preventing connection instability or physical damage caused by excessive local stress. This balanced force distribution is particularly important for high-density connectors due to their complex internal structure and dense contact points. Furthermore, using multiple connecting components 30 spaced apart along the length and / or width of the high-density connector significantly enhances the overall structural stability of the connector, reducing deformation or bending that may occur due to single-point connections, and ensuring the geometric accuracy and electrical performance of the connecting terminals during use. In addition, the above arrangement allows for greater flexibility in selecting the number of connecting components 30 to meet different usage requirements and operating conditions, and also improves the processing flexibility for operators.

[0036] In this embodiment, the connecting component 30 is a single component located in the middle of the first connecting terminal 10 and the second connecting terminal 20. This centrally located connecting component 30 not only makes it easier for the operator to control the alignment and connection of the high-density connector, but also simplifies the manufacturing process and reduces production costs.

[0037] like Figures 2 to 6 As shown, the high-density connector also includes a mating assembly, which includes a first mating portion 40 and a second mating portion 50. The first mating portion 40 is disposed on the first connecting terminal 10, and the second mating portion 50 is disposed on the second connecting terminal 20. One of the first mating portion 40 and the second mating portion 50 is a protrusion, and the other is a first limiting recess. The protrusion extends into the first limiting recess and engages with it for limiting.

[0038] In this embodiment, the first mating part 40 is a protrusion, and the fastener 31 passes through the protrusion; the second mating part 50 is a first limiting recess, which communicates with the mating recess 32. Thus, the mating of the protrusion and the first limiting recess provides precise positioning for the two connecting terminals during insertion and removal, ensuring alignment of the two connecting terminals during connection, thereby improving the accuracy and reliability of the connection and reducing connection failures or poor contact caused by misalignment or misfitting. Simultaneously, the specific shape of the protrusion and the first limiting recess serves as a foolproof feature, preventing operators from mistakenly inserting the connector in the wrong direction or misaligned, reducing equipment damage or functional failure caused by human error, and further ensuring the safe operation of electronic equipment.

[0039] Specifically, since the first mating part 40 is a protrusion and the second mating part 50 is a first limiting recess, the operator can determine which is the first connecting terminal 10 and which is the second connecting terminal 20 based on the shape of the first mating part 40 and the second mating part 50, ensuring that the first connecting terminal 10 is located above the second connecting terminal 20, thereby playing a foolproof role.

[0040] In other embodiments not shown in the accompanying drawings, the first mating part is a first limiting recess, and the second mating part is a protrusion that extends into the first limiting recess and engages with it.

[0041] like Figure 3As shown, the protrusion has a second limiting recess 41, and a limiting protrusion 311 is provided on the outer peripheral surface of the fastener 31. The limiting protrusion 311 extends into the second limiting recess 41 and engages with it to limit the fastener 31 axially. Thus, by providing a limiting protrusion 311 on the outer peripheral surface of the fastener 31 to engage with the second limiting recess 41 on the protrusion, the fastener 31 can be effectively prevented from accidentally loosening or shifting under axial force, ensuring the continuity and stability of the connection.

[0042] Optionally, the limiting protrusion 311 can be arc-shaped or annular. This design allows for greater flexibility in the shape selection of the limiting protrusion 311 to meet different usage requirements and working conditions, and also improves the processing flexibility of the operator.

[0043] In this embodiment, the limiting protrusion 311 is annular.

[0044] like Figures 2 to 4 As shown, the first connecting terminal 10 includes a first plate 11 and a first terminal portion 12, with a protrusion and the first terminal portion 12 spaced apart on the surface of the first plate 11. The protrusion includes a second plate 42 and a surrounding plate 43. The second plate 42 is disposed opposite to the first plate 11 and connected to the first plate 11 via the surrounding plate 43. At least a portion of the first plate 11, the surrounding plate 43, and the second plate 42 form a second limiting recess 41. The second plate 42 has a first through hole 421, through which at least a portion of the fastener 31 passes and is threadedly connected to the mating recess 32. Thus, the combination of the second plate 42, the surrounding plate 43, and the first plate 11 forms a stable frame structure surrounding the fastener 31. This not only increases the mechanical strength of the connection area but also improves the structural stability of the entire high-density connector, effectively preventing loosening or damage to the connection due to external forces during use.

[0045] In this embodiment, the first plate 11 and the second plate 42 are arranged parallel to each other. The second limiting recess 41 cooperates with the limiting protrusion 311 on the fastener 31 to provide precise axial limiting during the rotation of the fastener 31, ensuring accurate positioning of the fastener 31 during operation and avoiding connection problems caused by fastener 31 positional misalignment or wobbling. Thus, through the above design of the first connecting terminal 10, not only is the mechanical strength and electrical performance of the high-density connector significantly enhanced, but the assembly process is also simplified and maintenance efficiency is improved.

[0046] In this embodiment, the surrounding plate 43 is an annular plate.

[0047] like Figure 2 and Figure 3As shown, the first plate 11 has a second through hole 111 communicating with the second limiting recess 41. The fastener 31 includes a column, and the limiting protrusion 311 is disposed on the outer surface of the column. The first end of the column passes through the second through hole 111, and the second end of the column passes through the first through hole 421 and is threadedly connected to the mating recess 32. Thus, both ends of the column respectively mate with the first plate 11 and the second plate 42. Through the threaded connection of the fastener 31, a stable mechanical connection is formed between the first connecting terminal 10 and the second connecting terminal 20, significantly enhancing the structural strength of the high-density connector. Even under high vibration or high stress environments, the stability and reliability of the high-density connector can be maintained.

[0048] In this embodiment, the second end of the column is an externally threaded section, which passes through the first through hole 421 and is threadedly connected to the mating recess 32. Workers can tighten the fastener 31 by operating the first end of the column, thus reducing the difficulty of operation.

[0049] Specifically, the extension direction of the column is perpendicular to the first plate 11. The first connecting terminal 10 is tightened onto the second connecting terminal 20 by screwing the fastener 31 downward along the extension direction of the fastener 31.

[0050] Optionally, the end face of the first end of the column is flush with the first plate 11; or, the height of the end face of the first end of the column is lower than the height of the plate surface of the first plate 11. In this way, the above arrangement can avoid movement or structural interference between the column and other components inside the server.

[0051] like Figure 5 and Figure 6 As shown, the second connecting terminal 20 includes a third plate 21, a connecting platform 22, and a second terminal portion 23. The connecting platform 22 and the second terminal portion 23 are spaced apart on the surface of the third plate 21. The height of the connecting platform 22 is lower than the height of the second terminal portion 23, so that a first limiting recess is formed between the connecting platform 22 and the second terminal portion 23. A mating recess 32 extends from the platform surface of the connecting platform 22 toward the third plate 21. This height difference between the connecting platform 22 and the second terminal portion 23 forms the first limiting recess, which can mate with a protrusion on the first connecting terminal 10, providing precise alignment and limiting functions. This ensures that the first connecting terminal 10 and the second connecting terminal 20 can accurately align during the connection process, reducing connection failures or poor contact caused by inaccurate alignment. Simultaneously, the above configuration simplifies the structure of the second connecting terminal 20, making it easier to manufacture and implement, and reducing the manufacturing cost and difficulty of the second connecting terminal 20.

[0052] In this embodiment, the platform of the connecting platform 22 is arranged parallel to the third plate 21, so that the first limiting recess and the mating recess 32 are located on both sides of the platform.

[0053] Optionally, the mating recess 32 is an internally threaded hole; and / or, the connecting platform 22 has an annular hole 221, which surrounds the mating recess 32. In this way, the internally threaded hole, serving as the mating recess 32, forms a threaded connection with the externally threaded section on the fastener 31, providing a stable and reliable mechanical connection. The threaded connection can withstand a large load, preventing loosening or detachment due to vibration or external force during the connection process. Simultaneously, the aforementioned arrangement of the annular hole 221 can relieve stress in the mating recess 32, preventing stress concentration at the connection point between the fastener 31 and the mating recess 32, which could affect the structural strength of the connecting assembly 30.

[0054] In this embodiment, the mating recess 32 is an internally threaded hole, and the connecting platform 22 has an annular hole 221, which is arranged around the mating recess 32.

[0055] Alternatively, fastener 31 may be a screw or bolt.

[0056] This application also provides a server (not shown) including the high-density connector described above.

[0057] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0058] By using a threaded connection between the fastener and the mating recess, the large insertion and extraction force that would normally be applied in a straight line is transformed into the torque required to rotate the fastener. This effectively reduces the force required to connect and disconnect high-density connectors, significantly improving operational convenience and efficiency, and solving the problem of increased labor intensity for workers during the insertion and removal of high-density connectors in related technologies. Specifically, when connecting the first and second connecting terminals, the fastener is aligned with the mating recess, and by screwing in the fastener, the first and second connecting terminals gradually engage to achieve electrical connection. Because the screwing-in process provides a uniform and stable force, the required insertion force is significantly reduced compared to traditional direct insertion and removal methods. When separating the first and second connecting terminals, the fastener is unscrewed, and the first and second connecting terminals can separate due to their own structural characteristics or slight external force, again saving extraction force. Simultaneously, because the above process reduces insertion and extraction force, it also reduces the risk of accidental damage to the circuit boards or other electronic components surrounding the high-density connector during insertion or removal, helping to extend the service life of electronic equipment and improve system reliability.

[0059] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
