Description

Technical Field

[0001] This application relates to the field of server technology, and more particularly to connection devices and maintenance equipment. Background Technology

[0002] Currently, in modern server architectures, PCIe network interface cards (NICs) serve as core network components, undertaking crucial functions for data exchange and network connectivity. Their performance and maintainability directly impact the overall operational efficiency of the server. In traditional server designs, PCIe NICs are typically integrated inside the chassis. Maintenance operations such as debugging, logging, and firmware updates require soldering DuPont wires to the NIC's serial port using a soldering iron, followed by the use of appropriate maintenance tools.

[0003] However, the above-mentioned traditional maintenance methods have the following problems:

[0004] Problem 1: As a concentrated area of ​​high-density electronic equipment, server rooms typically contain a large number of exposed cables, metal racks, and precision circuits. Soldering irons, being high-temperature tools (operating temperatures typically reaching 300-400℃), can easily cause overheating and damage to components such as capacitors and resistors if their hot tips accidentally come into contact with them. Furthermore, server rooms often contain dust, fibers, and other impurities that can ignite under high temperatures, potentially leading to localized combustion. Accidental contact between the soldering tip and the metal rack could even generate sparks that ignite the insulation of surrounding cables, posing a significant fire safety hazard. More importantly, the internal circuitry of servers is constantly energized during operation. A moment's inattention during soldering could cause a short circuit due to DuPont wires accidentally touching live pins, potentially burning out the network card or motherboard and even causing electric shock.

[0005] Question 2: The spacing between the serial ports of the network card is small. If the amount of solder is not properly controlled during manual soldering, solder balls and solder bridges will remain between the pins. These residual solders may gradually oxidize and spread under the high temperature environment of long-term operation of the equipment, eventually leading to short circuits between adjacent pins, causing abnormal network card communication or even hardware failure.

[0006] Question 3: Manually soldered DuPont wires lack a mechanical fixing structure, relying solely on the strength of the connection between the solder joint and the conductor to maintain contact. Continuous vibrations from server fans in the server room, disturbances from air conditioning airflow, and even minor bumps during personnel inspections can all lead to fatigue fracture of the solder joint or wire detachment. More importantly, the DuPont wires themselves are relatively thin, resulting in a small contact area with the solder joint. During frequent plugging and unplugging of equipment for debugging, the solder joint is easily pulled away from the base of the network card pin, causing irreversible hardware damage. This unstable connection method often leads to frequent data packet loss and communication interruptions during serial port debugging, significantly increasing the time and cost of troubleshooting. Utility Model Content

[0007] This application provides a connection device and a maintenance equipment to at least solve the technical problems in the related art of server network cards, such as high maintenance difficulty, low maintenance efficiency, and security risks during maintenance.

[0008] This application provides a connection device, comprising: a mounting structure including a mounting portion for mounting a component to be maintained; a first electrical connection assembly for connecting the mounting portion and a server; and a second electrical connection assembly for connecting the component to be maintained and a maintenance device. The second electrical connection assembly includes a connection portion disposed on the mounting structure, the connection portion being located on one side of the component to be maintained. The connection portion is movably disposed and has a clearance position and a connection position. During the installation of the component to be maintained, the connection portion moves toward the side away from the component to the clearance position to avoid the component to be maintained. After the component to be maintained is installed in place, the connection portion moves toward the component to the connection position to establish an electrical connection with the component to be maintained.

[0009] This application also provides a maintenance device, which includes a connection device and a maintenance device. The maintenance device is electrically connected to the component to be maintained via the connection device, and the maintenance device is electrically connected to a server via the connection device; wherein, the connection device is the connection device described above.

[0010] When staff need to debug or maintain the PCIe network card, they can unplug the PCIe network card from the server and insert it into the installation unit. Then, the first electrical connection component connects the installation unit to the PCIe network card's insertion port on the server, and the second electrical connection component connects the PCIe network card to the maintenance device. This allows for debugging and maintenance of the PCIe network card from outside the server. Furthermore, to overcome the non-fixed connection of the PCIe network card's electrical connection port (network card serial port) (traditional soldering of DuPont wires ensures a reliable connection between the DuPont wires and the PCIe network card), this application employs an active motion connection for the connection part. Besides being able to move to a clearance position to avoid obstructing the installation process of the PCIe network card, more importantly, after the PCIe network card is installed, the connection part can actively move to contact and electrically connect with the fixedly installed PCIe network card, thus achieving a reliable connection. As can be seen, the connection device in this application makes the overall debugging and maintenance process of the component to be maintained (PCIe network card) completely free from soldering, requiring only simple plug-and-play connection operations. It is not only simple to operate and highly efficient, but also avoids the potential server damage and safety hazards caused by high-temperature soldering. Thus, it solves the technical problems of high maintenance difficulty, low maintenance efficiency and safety hazards in the maintenance process of server network cards in related technologies.

[0026] 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.

[0027] Embodiments of this application provide a connection device and a maintenance device, wherein both the server and the heat dissipation module include the connection device described below. The connection device is described in detail below in conjunction with its structure and function.

[0028] like Figures 1 to 6As shown, the connection device includes a mounting structure 10, a first electrical connection assembly 20, and a second electrical connection assembly 30. The mounting structure 10 includes a mounting portion 11 for mounting the component 1 to be maintained. The first electrical connection assembly 20 connects the mounting portion 11 and the server. The second electrical connection assembly 30 connects the component 1 to be maintained and the maintenance device. The second electrical connection assembly 30 includes a connection portion 31 disposed on the mounting structure 10, located on one side of the component 1 to be maintained. The connection portion 31 is movably disposed and has a clearance position and a connection position. During the installation of the component 1 to be maintained, the connection portion 31 moves to the clearance position away from the component 1 to avoid it. After the component 1 to be maintained is installed in place, the connection portion 31 moves towards the component 1 to the connection position to establish an electrical connection with it.

[0029] When staff need to debug or maintain the PCIe network card (PCIe network card), they can unplug the PCIe network card from the server and insert it into the installation unit 11. Then, they can operate the first electrical connection component 20 to electrically connect the installation unit 11 to the PCIe network card insertion port of the server, and then operate the second electrical connection component 30 to electrically connect the PCIe network card to the maintenance device. This allows the PCIe network card to be debugged and maintained from outside the server. Meanwhile, to overcome the non-fixed connection of the electrical connection port (network card serial port) of the component to be maintained 1 (PCIe network card) (traditional soldering of DuPont wires can ensure a reliable connection between the DuPont wires and the PCIe network card), the connecting part 31 in this embodiment adopts an active motion connection. Besides the fact that the connecting part 31 can move to a clearance position to avoid the installation process of the component to be maintained 1 (PCIe network card), more importantly, after the component to be maintained 1 (PCIe network card) is installed, the connecting part 31 can actively move to contact and electrically connect with the fixedly installed component to be maintained 1 (PCIe network card), thereby achieving a reliable connection. It can be seen that the connection device in this embodiment makes the overall debugging and maintenance process of the component to be maintained 1 (PCIe network card) completely solder-free, requiring only simple plug-and-play connection operations. This is not only simple to operate and highly efficient, but also avoids the potential server damage and safety hazards caused by high-temperature soldering, thus solving the technical problems of high maintenance difficulty, low maintenance efficiency, and safety hazards in the maintenance process of server network cards in related technologies.

[0030] In this embodiment, the component to be maintained, 1, is a PCIe network card.

[0031] In this embodiment, the second electrical connection assembly 30 further includes a first electrical connector 36, which has a connecting portion 31.

[0032] In this embodiment, the mounting part 11 is a slot structure, that is, the component to be maintained 1 is inserted and fixed on the mounting part 11.

[0033] like Figure 1 , Figure 5 and Figure 6 As shown, the second electrical connection assembly 30 also includes an elastic portion 32, which is connected to the connecting portion 31 to drive the connecting portion 31 to move. Specifically, when the component to be maintained 1 abuts against the connecting portion 31, causing the elastic portion 32 to elastically deform, the connecting portion 31 moves away from the component to be maintained 1; when the elastic portion 32 returns to its elastic deformation, it drives the connecting portion 31 to extend into the connecting recess 101 of the component to be maintained 1. This arrangement simplifies the structure for realizing the movement of the connecting portion 31, making it easier to manufacture and implement, thereby reducing the manufacturing cost of the second electrical connection assembly 30.

[0034] Optionally, the elastic part 32 is a spring.

[0035] In this embodiment, the connecting recess 101 is the serial port of the PCIe network card.

[0036] In this embodiment, when the connecting part 31 moves to the connecting position, the elastic part 32 is in a compressed state to press the connecting part 31 against the inner wall of the connecting recess 101. In this way, by pressing the connecting part 31 against the inner wall of the connecting recess 101 by the elastic part 32, the electrical connection stability between the connecting part 31 and the component to be maintained 1 can be further improved, so as to avoid the loss of contact between the two and the resulting reduction in maintenance and debugging efficiency.

[0037] In this embodiment, the connecting part 31 is a conical metal part, the conical end of which is used to extend into the connecting recess 101, and the elastic part 32 is connected to the bottom surface of the connecting part 31. In this way, the inclined outer surface of the connecting part 31 can play a guiding role in the process of the connecting part 31 extending into the connecting recess 101, reducing the difficulty of the connecting part 31 extending into the connecting recess 101.

[0038] It is understandable that by connecting the tip and pressing it with the elastic part 32, the electrical connection stability between the connecting part 31 and the part to be maintained 1 can be maximized.

[0039] In this embodiment, the bottom diameter of the connecting portion 31 is larger than the diameter of the connecting recess 101 to prevent the connecting portion 31 from being completely inserted into the connecting recess 101.

[0040] like Figure 1 , Figure 5 and Figure 6As shown, the second electrical connection assembly 30 also includes a magnetic suction part 33, which is used to magnetically engage with the mounting structure 10. When the magnetic suction part 33 is magnetically engaged with the mounting structure 10, the connection part 31 is fixed; when the magnetic suction part 33 is separated from the mounting structure 10, the connection part 31 is movably disposed relative to the mounting structure 10. In this way, by using the magnetic attraction of the magnetic suction part 33 to fix the connection part 31, thereby ensuring that it can be aligned with the connection recess 101 of the component to be maintained after installation, subsequent connection can be achieved. Simultaneously, the operator can forcefully pull off the magnetic suction part 33 and re-engage it after adjusting its position, so that the setting position of the connection part 31 can be adapted to components 1 of different specifications and sizes (where the position of the connection recess 101 is different), thereby improving the versatility of the connection device.

[0041] In this embodiment, the magnetic attraction part 33 is a cylindrical magnet structure, the elastic part 32 is disposed on the upper surface of the magnetic attraction part 33, and the connecting part 31 is disposed on the elastic part 32 to form the first electrical connector 36.

[0042] It is understandable that the elastic part 32 can not only provide elastic force to the connecting part 31 in the extending direction of the magnetic part 33, but also provide a certain deformation range in the radial direction of the magnetic part 33, so as to reduce the magnetic position accuracy requirement of the magnetic part 33, and ensure that the connecting part 31 can extend into the connecting recess 101 and realize electrical connection.

[0043] like Figures 1 to 4 As shown, the mounting structure 10 also includes a base portion 12 and a support portion 13, with the mounting portion 11 disposed on the base portion 12. The support portion 13 is disposed on the base portion 12 and is located on one side of the mounting portion 11. The support portion 13 magnetically engages with the magnetic attraction portion 33. Thus, this arrangement provides support and a magnetic foundation for the magnetic attraction portion 33 through the support portion 13; furthermore, it simplifies the structure of the mounting structure 10, making it easier to manufacture and implement.

[0044] In this embodiment, both the base portion 12 and the support portion 13 are plate-shaped structures. The base portion 12 is placed horizontally, while the support portion 13 is vertically mounted on the base portion 12.

[0045] In this embodiment, both the base portion 12 and the support portion 13 are made of stainless steel plates, and the outer surface is coated with an insulating layer to eliminate the risk of electric shock, while also facilitating magnetic attraction of the magnetic part 33.

[0046] In this embodiment, after the component to be maintained 1 is installed, there is a gap L1 between the component to be maintained 1 and the support part 13, the connecting recess 101 has a depth L2, and the first electrical connector 36 has a length L3, where L3 > (L1 + L2), to ensure that the first electrical connector 36 can make close contact with the inner wall of the connecting recess 101 (generating a clamping force) after it extends into the connecting recess 101.

[0047] It should be noted that the structure of the installation structure 10 is not limited to this, and the staff can adjust the structure of the installation structure 10 according to the actual structure and usage requirements.

[0048] like Figures 1 to 4 As shown, the first electrical connection assembly 20 includes an electrical connection structure 21 and a first flexible conductive element 22. The electrical connection structure 21 is used for electrical connection with the server. The electrical connection structure 21 is electrically connected to the mounting part 11 through the first flexible conductive element 22. In this way, the flexible deformation of the first flexible conductive element 22 can adapt to the narrow space inside the server, thereby reducing the difficulty of electrical connection for the staff.

[0049] In this embodiment, the electrical connection structure 21 is a PCIe header for insertion into the PCIe slot of the server to achieve electrical connection.

[0050] In this embodiment, the first flexible conductive element 22 is a wire.

[0051] like Figures 1 to 4 As shown, the second electrical connection assembly 30 also includes a second electrical connector 34 and a second flexible conductive member 35. The second electrical connector 34 is disposed on the mounting structure 10 and is used for electrical connection with the maintenance device. The connection portion 31 is electrically connected to the second electrical connector 34 through the second flexible conductive member 35. In this way, the flexible deformation of the second flexible conductive member 35 can adapt to the narrow space of the server room, thereby reducing the difficulty of electrical connection for staff.

[0052] In this embodiment, the second electrical connector 34 is a connector.

[0053] In this embodiment, the second flexible conductive element 35 is a wire.

[0054] like Figures 1 to 4 As shown, the connecting device also includes a heat dissipation structure 40, which is mounted on the mounting structure 10. The heat dissipation structure 40 includes fan blades that are rotatably mounted to dissipate heat from the component 1 to be maintained. Thus, the above arrangement allows the heat dissipation structure 40 to cool the component 1 to be maintained during the debugging and maintenance process, preventing overheating and damage, thereby improving the safety of debugging and maintaining the component 1.

[0055] In this embodiment, the heat dissipation structure 40 is a fan structure.

[0056] like Figures 1 to 6 As shown, the first electrical connection assembly 20 further includes an elastic portion 32 and a magnetic suction portion 33. The elastic portion 32 is disposed on the magnetic suction portion 33, and the connecting portion 31 is disposed on the elastic portion 32. The elastic portion 32 drives the connecting portion 31 to move. When the component to be maintained 1 abuts against the connecting portion 31, causing the elastic portion 32 to undergo elastic deformation, the connecting portion 31 moves toward the side away from the component to be maintained 1. When the elastic portion 32 recovers its elastic deformation to drive the connecting portion 31 to move to the connection position, the elastic portion 32 is in a compressed state to press the connecting portion 31 tightly against the connecting recess 1. On the inner wall of 01; the magnetic part 33 is used to magnetically engage with the mounting structure 10, so as to fix the connecting part 31 when the magnetic part 33 and the mounting structure 10 are magnetically engaged; so as to allow the connecting part 31 to be movably disposed relative to the mounting structure 10 when the magnetic part 33 and the mounting structure 10 are separated; the first electrical connection assembly 20 also includes an electrical connection structure 21 and a first flexible conductive element 22, the electrical connection structure 21 is used to make an electrical connection with the server; the electrical connection structure 21 is electrically connected to the mounting part 11 through the first flexible conductive element 22. The second electrical connection assembly 30 also includes a second electrical connector 34 and a second flexible conductive element 35, the second electrical connector 34 is disposed on the mounting structure 10, the second electrical connector 34 is used to make an electrical connection with the maintenance device; the first electrical connector 36 is electrically connected to the second electrical connector 34 through the second flexible conductive element 35.

[0057] The usage process of the connection device in this embodiment is as follows:

[0058] In use, insert the PCIe network card into the mounting part 11, open the heat dissipation structure 40, adjust the magnetic position of the first electrical connector 36 according to the specifications of the component to be maintained 1, so that the first electrical connector 36 is basically aligned with the connection recess 101, and then the connection part 31 extends into the connection recess 101 under the action of the elastic part 32 to achieve a reliable electrical connection. Then connect the second electrical connector 34 to the maintenance device. With the server powered off, insert the electrical connection structure 21 into the corresponding slot inside the server. Finally, turn on the server to perform PCIe network card debugging, firmware flashing and other related operations.

[0059] This application also provides a maintenance device, which includes a connection device and a maintenance device. The maintenance device is electrically connected to the component 1 to be maintained via the connection device, and the maintenance device is electrically connected to the server via the connection device. The connection device is the connection device described above.

[0060] It should be noted that "multiple" in the above embodiments refers to at least two.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely 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 various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
