Description

Technical Field

[0001] This application relates to the field of computing devices, and more particularly to a computing device. Background Technology

[0002] Internet service providers, enterprises, research institutions and other organizations generally have a large demand for computing. Therefore, it is necessary to build computing clusters that can support storage, computing and transmission needs. These computing clusters are also known as data centers, and they include at least one computing device.

[0003] With the rapid development of communication technology, computing devices are becoming increasingly integrated and thermally dense, leading to greater demands for heat dissipation. Traditional air-cooling combined with air conditioning is not only energy-intensive but also environmentally unfriendly, making it increasingly difficult to meet these requirements. In recent years, immersion liquid cooling technology has gradually been applied to the cooling and heat dissipation of computing devices as a new cooling process.

[0004] In related technologies, computing devices include a housing and electronic components housed within the housing. In scenarios where these electronic components need to connect to external devices, cables are required to pass through the housing. The housing contains a cooling medium that immerses the electronic components. Through the circulation and / or phase change of the cooling medium, the heat generated by the electronic components can be removed. However, due to the poor sealing of cables, the cooling medium may enter between the cable sheath and the cable core, causing leakage. This phenomenon is more pronounced under certain pressure conditions inside the housing, which greatly limits the application of immersion liquid cooling technology in computing device cooling.

[0005] Therefore, how to provide a solution to better overcome or alleviate the above-mentioned defects remains a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] This application provides a computing device in which the connecting cable for connecting to external devices is located on the outside of the computing device housing and passes through the housing wall by a solid transition connector to connect the connecting devices and connecting cable inside the housing. This can better avoid sealing problems caused by the connecting cable and thus improve the sealing performance of the computing device.

[0007] In a first aspect, embodiments of this application provide a computing device, which may specifically be a server, including a housing and a transition connector. Electronic devices are housed within the housing; these electronic devices can be of various types, such as memory, processor, network interface card (NIC), and switching module. NICs and switching modules, for example, require signal connections to external devices; these types of electronic devices can be referred to as connection devices. The housing forms the external frame of the computing device to protect the internal electronic devices. The housing wall has insertion holes. The transition connector is a solid structure, passing through the insertion holes and sealingly connected to them to achieve a seal between the outer wall of the transition connector and the inner wall of the insertion hole. The transition connector includes a first electrical connection portion located inside the housing, a second electrical connection portion located outside the housing, and a signal transmission portion electrically connected between the first and second electrical connection portions; wherein the first electrical connection portion is electrically connected to the connection device inside the housing, and the second electrical connection portion is electrically connected to the external device via a connecting cable to achieve signal transmission between the connection device and the external device.

[0008] Using the above-described solution, this embodiment places the connecting cable for external devices on the outside of the housing, and uses a transition connector to pass through the housing wall. The transition connector then connects the internal connecting devices to the external connecting cable. This perfectly avoids the sealing problems caused by the connecting cable. Furthermore, the transition connector itself is a solid structure; as long as the sealing design between the outer wall of the transition connector and the inner wall of the insertion hole is ensured, the transition connector itself will not introduce new sealing problems, thus significantly improving the sealing performance of the computing device. This facilitates the widespread application of immersion liquid cooling technology in computing device cooling scenarios.

[0009] Based on the first aspect, the present application also provides a first implementation of the first aspect: the housing is filled with a cooling medium, and the first electrical connection part and the connecting device are both immersed in the cooling medium to ensure cooling and heat dissipation at the connection between the first electrical connection part and the connecting device.

[0010] Based on the first aspect, this application also provides a second implementation of the first aspect: the computing device further includes a first sealing component, which can be disposed between the outer wall surface of the transition connector and the inner wall of the insertion hole, for realizing a sealed assembly between the transition connector and the insertion hole.

[0011] The first sealing components include adhesives, rubber rings, etc. Among them, adhesives not only achieve the sealing function, but also bond and fix the transition connectors, which can better ensure the reliability of the assembly of the transition connectors relative to the housing. This can largely avoid the situation where the transition connectors wobble relative to the housing during installation and use. The reduction of wobble itself is also conducive to ensuring the integrity of the sealing structure, which can further improve the reliability of the seal.

[0012] The first sealing component can be a single type of sealing element, or it can be a combination of multiple types of sealing elements, such as the combined use of adhesives and rubber rings.

[0013] Based on the first aspect, this application also provides a third implementation of the first aspect: the computing device further includes a flange and a second sealing component; the flange is disposed on the outer wall surface of the transition connector and fixed relative to the transition connector; the flange can be assembled to the housing, and the connection between the flange and the housing can be a screw connection, or of course, it can also be a welding, snap-fit, riveting or other connection methods, as long as the reliability of the connection can be guaranteed; the second sealing component is disposed between the flange and the housing to achieve the sealing performance between the flange and the housing, and the type of the second sealing component can refer to the aforementioned first sealing component.

[0014] Based on the third implementation of the first aspect, this application also provides a fourth implementation of the first aspect: the flange and the transition connector can be a separate structure, where the separate structure means that the two can be manufactured separately; the flange can be provided with a through hole, and the transition connector is sealed and inserted into the through hole.

[0015] The connection method between the flange and the transition connector can be varied, such as welding, bonding, screwing, riveting, or snap-fitting, as long as the reliability of the connection can be guaranteed. If the sealing performance between the transition connector and the through-hole cannot be guaranteed after the flange and transition connector are connected, sealing elements such as sealing rings, gaskets, sealing fillers, and adhesives can be configured to ensure the sealing between the transition connector and the flange. In fact, the aforementioned second sealing component can also be used to simultaneously achieve a seal between the flange and the transition connector.

[0016] The flange may also be provided with mounting holes. In practice, fasteners such as screws can be configured to pass through the mounting holes and fix the flange in place.

[0017] The flange can have two or more through holes. In this way, one flange can accommodate the installation of multiple transition connectors, reducing the number of flanges and simplifying installation.

[0018] Based on the first aspect, or any of the first to fourth embodiments of the first aspect, this application also provides a fifth embodiment of the first aspect: the transition connector is a circuit board.

[0019] The signal transmission section includes conductive metal laid on the surface of the circuit board and / or embedded in the circuit board. This includes three options: the signal transmission section includes only conductive metal laid on the surface of the circuit board; the signal transmission section includes only conductive metal embedded in the circuit board; and the signal transmission section includes conductive metal laid on the surface of the circuit board and embedded in the circuit board. The type of conductive metal is not limited here; generally, it can be copper.

[0020] The number of conductive metals is the same as the number of wire cores in the connecting cable, and the conductive metals are electrically connected to the corresponding wire cores in the connecting cable.

[0021] Based on the fifth implementation of the first aspect, this application also provides a sixth implementation of the first aspect: the circuit board is a flexible circuit board.

[0022] Flexible circuit boards possess a certain degree of flexibility and deformation capability, allowing them to better adapt to changes in the installation position of connecting cables. In practical applications, they offer greater adjustability, meeting the requirements of flexible assembly. In particular, they can adapt to and absorb connection tolerances with external devices, significantly improving connection convenience and consequently enhancing connection reliability and signal transmission stability. Furthermore, through their inherent flexibility, flexible circuit boards can effectively absorb vibrations and installation tension from computing equipment during actual use, mitigating the impact of vibrations or installation tension on the sealed assembly of the circuit board.

[0023] Based on the fifth embodiment of the first aspect, this application also provides a seventh embodiment of the first aspect: the circuit board can also be a rigid circuit board, and the connecting device connected to the circuit board is fixedly disposed in the housing; at this time, the computing device further includes a first flexible connector, which is electrically connected between the first electrical connection part and the connecting device.

[0024] The first flexible connector can be a flexible circuit board, cable, etc. Through the flexible transition of the first flexible connector, the defects caused by assembly errors and other factors that the first electrical connection and the connecting device cannot be accurately connected can be better adapted, and the connection reliability between the connecting device and the first electrical connection can be improved, thereby improving the stability of signal transmission.

[0025] Based on the fifth embodiment of the first aspect, this application also provides an eighth embodiment of the first aspect: the circuit board is a rigid circuit board, and the connecting device connected to the circuit board is equipped with a floating mechanism. Through this floating mechanism, the position of the connecting device inside the housing can be flexibly adjusted, thus ensuring accurate connection between the connecting device and the first electrical connection part, and improving the reliability of the connection and the stability of signal transmission.

[0026] The floating mechanism includes several positioning posts, and the connecting device is provided with several positioning holes. Each positioning post is inserted into a corresponding positioning hole, and at least some of the positioning posts are equipped with a first elastic part and a second elastic part, which are located on opposite sides of the connecting device along the axial direction of the positioning posts. Through the elastic deformation of the first and second elastic parts, the connecting device can move in the axial direction of the positioning posts, thereby achieving the technical purpose of adjusting the installation position of the connecting device along the axial direction of the positioning posts. The two elastic parts can be springs, bellows, or other forms of elastic elements, as long as they can achieve the function of elastic deformation.

[0027] In each positioning hole, at least some positioning holes and corresponding positioning posts have radial floating clearances. The connecting device can also be positioned in a plane perpendicular to the axial direction of the positioning post, so that the connecting device has more positioning adjustment directions and can better adapt to situations where direct connection is not possible due to assembly errors between the connecting device and the rigid circuit board.

[0028] In the connector and the rigid circuit board, one can be equipped with an alignment sleeve, and the other with an alignment shaft, which can be inserted into the alignment sleeve. In this way, the reaction force generated by the floating mechanism on the connector can be absorbed by the alignment shaft and the alignment sleeve, which can prevent the force from acting directly on the connection position between the connector and the first electrical connection part. This reduces the stress at the connection position between the connector and the first electrical connection part, and is more conducive to ensuring the reliability of the connection and the stability of signal transmission.

[0029] Based on the first aspect, or based on any one of the first to eighth embodiments of the first aspect, this application also provides a ninth embodiment of the first aspect: the first electrical connection part is provided with gold fingers, and the connecting device connected to the transition connector is provided with a connecting socket. The first electrical connection part is inserted into the connecting socket to ensure convenient installation; the second electrical connection part is provided with solder pads for connecting to the connecting cable. The second electrical connection part is located on the outside of the housing, with a large operating space, which facilitates soldering operations and improves the connection reliability between the second electrical connection part and the connecting cable. It can also greatly reduce the possibility of damage to the connection between the second electrical connection part and the connecting cable caused by human factors. Attached Figure Description

[0048] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] With the rapid development of communication technology, internet service providers, enterprises, research institutions, and others have generally begun to build data centers (also known as computing clusters) to support storage, computing, and transmission functions, in order to meet their data usage needs. The structure of a data center can be diverse.

[0050] Please refer to Figure 1 and Figure 2 , Figure 1 This is a structural diagram of one specific implementation of a data center. Figure 2 This is a structural diagram of a specific implementation of a chassis and its internal computing devices.

[0051] like Figure 1 As shown, in one exemplary embodiment, the data center 100 may include a server room 101 and at least one server rack 201. The server room 101 provides an isolated environment for the data center 100, isolating the server rack 201 from the outside world. It can be a permanent dwelling, a temporary tent, prefab house, or other temporary housing, or a container or cargo container that provides storage space. In specific applications, at least one side wall of the server room 101 may be provided with an entrance / exit door to facilitate the entry and exit of staff. The specific structural form, opening and closing method, and opening and closing control strategy of the entrance / exit door are not limited here, as long as the technical effect of allowing staff to enter and exit the data center 100 is achieved.

[0052] In some implementations, the data center 100 is also equipped with an air-cooled circulation system (not shown in the figure), which uses at least one air conditioning unit or fan unit to ventilate and cool the interior of the computer room 101 in order to ensure the internal environment of the computer room 101.

[0053] Combination Figure 2 The chassis 201 houses a computing device 202, which may be a server or similar device. The chassis 201 may contain mounting components for mounting and securing the computing device 202 within it. This embodiment of the invention does not limit the structural form of the mounting components, as long as they ensure reliable fixation of the computing device 202 within the chassis 201. For example, the mounting components may be a support plate installed on the inner wall of the chassis 201, and the computing device 202 may be fixed to the support plate using bolts or similar connectors.

[0054] In some embodiments, there can be multiple computing devices 202, and each computing device 202 can be distributed in different locations within the chassis 201. For example, the computing devices 202 can be distributed layer by layer inside the chassis 201. This embodiment can be found in [reference needed]. Figure 2 .

[0055] The chassis 201 may be equipped with a door 201a. When the door 201a is open, the interior of the chassis 201 can be exposed to facilitate the installation, inspection, replacement, and maintenance of the various computing devices 202. The number of doors 201a is not limited, and this is related to the structure and size of the computing devices 202. The opening and closing methods of the doors 201a include, but are not limited to, rotating opening and closing, sliding opening and closing, and retracting opening and closing. The locking devices required for the doors 201a can refer to existing technologies and are not limited here.

[0056] In other embodiments, the number of computing devices 202 may be one. In this embodiment, the computing device 202 can be placed independently, such as a server, in which case the aforementioned chassis 201 may not be included.

[0057] The computing device 202 includes a housing. The external structure of the housing is typically a cuboid, but it can also take other structural forms, such as a cylinder, depending on the specific application environment. The housing encapsulates at least one electronic device for at least one function, such as data storage, transmission, or computation. These electronic devices can be connected via cables to facilitate signal transmission. Simultaneously, some electronic devices, such as network interface cards (NICs) and switching modules, need to transmit signals to external devices, such as switching modules, located outside the housing. Traditionally, this is achieved by using cables that can pass through the housing walls to connect the internal electronic devices to the external devices. Taking the connection between a NIC and an external switching module as an example, the signals transmitted via the cable are high-speed signals, such as Ethernet signals or PCIe (Peripheral Component Interconnect Express) signals.

[0058] Electronic devices generate heat during operation, especially high-power-density devices, which produce significant amounts of heat. If this heat is not dissipated in time, the internal temperature of the computing device 202 will become too high, seriously affecting the normal operation of various electronic components; in severe cases, it may even cause accidents such as fires and explosions. Therefore, heat dissipation for electronic devices is essential.

[0059] In recent years, immersion liquid cooling technology has been increasingly used in computing devices 202, gradually becoming a relatively mainstream cooling process. Specifically, it involves filling the casing with a coolant to absorb heat generated by electronic components through the circulation and / or phase change of the coolant. Compared to the traditional air-cooling + air conditioning method, immersion liquid cooling offers numerous technological advantages, including environmental friendliness and low energy consumption. However, this process places high demands on the sealing of the computing device 202 to prevent coolant leakage during use.

[0060] Please refer to Figure 3 , Figure 3 This is a structural diagram of one specific implementation of a cable.

[0061] As mentioned earlier, for electronic devices that need to connect to external devices, cables can be used to pass through walls to establish a signal connection between the internal electronic devices and the external devices. The structure of cable 3 is roughly as follows: Figure 3As shown, it generally includes an outer sheath 31 and a wire core 32. The outer sheath 31 covers the wire core 32, and the wire core 32 has a portion extending out of the outer sheath 31, which can form the connection end of the wire core 32 with other components. In some embodiments, a dedicated connector 33 can also be configured. The connector 33 can be connected to the wire core 32 and is used for connection with other components; the structure of the connector 33 can be varied. Figure 3 The rectangle shown is just an example; it can also be in various structural forms such as ring, U-shape, and L-shape, depending on the specific way the connector 33 is fixed to other components.

[0062] In the above structure, a gap 34 exists inside the cable 3. This gap 34 can exist between the outer sheath 31 and the wire core 32; or, in embodiments with multiple wire cores 32, the gap 34 can also exist between each wire core 32. Furthermore, in practice, due to environmental limitations or installation tension, the cable 3 may be bent, which can easily cause wrinkles in the outer sheath 31, and in severe cases, even cracks; especially in outer sheaths 31 containing shielding layers made of aluminum foil, copper foil, etc. Thus, when the cable 3 passes through the shell wall of the computing device 202, the cooling medium inside the shell may leak out from the gap 34 or the crack, causing cooling medium leakage. This not only affects the cooling efficiency but also impacts the environment surrounding the computing device 202. This phenomenon is more pronounced in two-phase cooling scenarios with a certain pressure.

[0063] Therefore, this application provides a computing device in which cables connected to external devices are placed on the outside of the housing and pass through the housing wall by adding a solid transition connector. The transition connector then connects the internal electronic components to the external cables. The solid transition connector does not have the gaps found in cables 3, thus perfectly avoiding the sealing problems caused by cables. This ensures better cooling efficiency and protects the environment around the computing device 202, facilitating the widespread application of immersion liquid cooling technology in computing device cooling scenarios.

[0064] It should be noted that the aforementioned solid structure refers to a seamless structure, meaning the transition connector itself has no gaps. Therefore, there is no possibility of coolant leakage from the transition connector. Specifically, if the transition connector is formed using only one material, its structure is dense and gapless, such as a solid metal pillar or a rigid circuit board. Alternatively, if the transition connector is formed by combining components of multiple materials, based on specific manufacturing processes (such as one-piece injection molding or exposure curing), the components can be tightly connected without gaps.

[0065] For details, please refer to Figure 4 and Figure 5 , Figure 4 A simplified structural diagram of one specific embodiment of the computing device provided in this application. Figure 5 for Figure 4 A partial enlarged view of the intermediate transition connector and connecting cable, with the length of the connecting cable appropriately extended.

[0066] like Figure 4 As shown, the computing device 202 includes a housing 1, electronic components 2, cables, and transition connectors 4. The housing 1 forms the external frame of the computing device 202 and protects the internal components. The housing 1 has insertion holes (not shown in the figure), and the transition connectors 4 are sealed and inserted into these holes to achieve a sealed connection where the transition connectors 4 pass through the housing 1. The electronic components 2 can be housed within the housing 1; the type and number of electronic components 2 are not limited here. For ease of description, electronic components 2 that need to be connected to external devices can be referred to as connecting devices. It is understood that all electronic components 2 within the housing 1 can be connecting devices, or only some electronic components 2 can be connecting devices. The number of cables is one or more, with at least one used for connecting to external devices. For ease of description, the cable connecting to the external device can be referred to as connecting cable 3a, and this connecting cable 3a is located outside the housing 1. The transition connector 4 has a first electrical connection part and a second electrical connection part, wherein the first electrical connection part is located inside the housing 1 and is used to connect to the connecting device, and the second electrical connection part is located outside the housing 1 and is used to connect to the connecting cable 3a; the transition connector 4 also includes a signal transmission part, which is electrically connected between the first electrical connection part and the second electrical connection part and is used to realize signal transmission between the first electrical connection part and the second electrical connection part.

[0067] Using the above structure, in this embodiment, the transition connector 4 is sealed and inserted into the plug hole, and the connecting cable 3a is entirely placed on the outside of the housing 1. Thus, regardless of whether there are gaps or breaks in the connecting cable 3a, the sealing performance of the housing 1 will not be affected. Simultaneously, the transition connector 4 is a solid structure, without gaps, and will not introduce new sealing problems. This ensures a reliable seal for the computing device 202, thereby reducing coolant leakage, ensuring effective cooling, and protecting the environment around the computing device 202. This allows for better promotion and application of immersion cooling technology in the computing device field.

[0068] All cables 3 in the computing device 202 can be connecting cables 3a. Alternatively, some cables 3 can be used to connect the various electronic devices 2 inside the computing device 202 to realize the transmission of data signals inside the computing device 202. These cables 3 can be called internal cables (not shown in the figure). Since the internal cables are located inside the housing 1, they will not affect the sealing performance of the housing 1.

[0069] Here, the embodiments of this application do not limit the specific structural form of the first electrical connection part and the second electrical connection part. In practical applications, those skilled in the art can set it according to actual needs, as long as the reliability of the connection can be met. For example, both the first electrical connection part and the second electrical connection part can be provided with gold fingers 41 (the number is not limited, and the specific number depends on the actual needs); or, both the first electrical connection part and the second electrical connection part can be provided with pads 42 (the number is not limited, and the specific number depends on the actual needs); or, in the first electrical connection part and the second electrical connection part, one can be provided with gold fingers 41 and the other can be provided with pads 42, which is also feasible. As a preferred embodiment, the first electrical connection part can be provided with gold fingers 41. In this case, a connector can be configured on the connecting device. The connector has a connection socket, and the first electrical connection part can be directly plugged into the connection socket of the connector 91, which can improve the convenience of connection. The second electrical connection part can be provided with solder pads 42. The second electrical connection part is located on the outside of the housing 1, with a large operating space, which can facilitate soldering operations and improve the connection reliability between the second electrical connection part and the connecting cable 3a. It can also greatly reduce the possibility of damage to the connection between the second electrical connection part and the connecting cable 3a by human factors.

[0070] The housing 1 can contain a cooling medium that can immerse the electronic device 2, absorbing the heat dissipated by the device 2 through thermal conduction. This cooling medium can be a liquid or a two-phase medium; the specific type is not limited here. The housing 1 has a cooling medium inlet 12 and an outlet 13 on its wall for circulating the cooling medium. A pump and pipes are typically installed outside the housing 1 to facilitate the injection, circulation, and discharge of the cooling medium; the specific structure and distribution of these components are not explicitly defined here.

[0071] In practical applications, the cooling medium can immerse the first electrical connection and the connecting device.

[0072] The sealing assembly of the transition connector 4 can take various forms, as long as it can meet the technical requirements of the sealing assembly.

[0073] Please refer to Figure 6 and Figure 7 , Figure 6This is a schematic diagram of the structure when the transition connector 4 is connected to the housing 1 using adhesive. Figure 7 for Figure 6 The variation scheme.

[0074] like Figure 6 and Figure 7 As shown, in the first embodiment provided in this application, the transition connector 4 can be sealed and assembled to the housing 1 by an adhesive 5. The adhesive 5 can be used to fill the gap between the outer wall of the transition connector 4 and the inner wall of the insertion hole 11. This embodiment can be found in [reference needed]. Figure 6 Alternatively, the adhesive 5 can also be disposed on the inner side of the housing 1, as can be seen in this embodiment. Figure 7 Of course, the adhesive 5 can also be disposed on the outside of the housing 1.

[0075] The type of adhesive 5 is not limited here. As a requirement for use, adhesive 5 should not be corrosive to the transition joint 4, and adhesive 5 should have a certain degree of corrosion resistance to the cooling medium.

[0076] The adhesive 5 can seal the gap between the outer wall of the transition connector 4 and the inner wall of the insertion hole 11, thus acting as a first sealing component to achieve a seal and effectively prevent leakage of the cooling medium inside the housing 1. Furthermore, the adhesive 5 can also bond and fix the transition connector 4, ensuring the reliability of the assembly of the transition connector 4 relative to the housing 1. This significantly reduces the likelihood of the transition connector 4 shaking relative to the housing 1 during installation and use. Reduced shaking also helps maintain the integrity of the sealing structure, thereby improving the reliability of the seal.

[0077] Similar to the method of configuring adhesive 5, the transition connector 4 can also be assembled to the housing 1 by welding, thus achieving a sealed assembly of the transition connector 4 relative to the housing 1. In this case, the first sealing component is solder.

[0078] Please refer to Figure 8 , Figure 8 This is a schematic diagram of the structure when the transition connector 4 is connected to the housing 1 using a sealing ring 6.

[0079] like Figure 8 As shown, this application embodiment also provides a second implementation of the first sealing component. The first sealing component can be a sealing ring 6, which can be disposed between the outer wall surface of the transition connector 4 and the inner wall of the insertion hole 11 to seal the gap between them. Simultaneously, the sealing ring 6 and the transition connector 4 can form a tight fit to create a certain interference fit, thereby ensuring a high degree of reliability in the assembly of the transition connector 4 relative to the housing 1.

[0080] The sealing ring 6 can be a rubber ring, etc., and there can be one or more. When there are multiple sealing rings 6, they can be arranged at axial intervals along the insertion hole 11. Figure 8 In the scheme shown, there can be two sealing rings 6.

[0081] During assembly, a groove can be provided on the inner wall of the insertion hole 11 for the installation and positioning of the sealing ring 6. Alternatively, a groove can be provided on the outer wall of the transition connector 4, which is also feasible.

[0082] It should be noted that the first sealing component is not necessarily a single type of component. For example, the adhesive 5, sealing ring 6, and solder mentioned above can all form a seal when used alone. Therefore, they can also form a seal when used in combination. In other words, the first sealing component can also include more types of sealing components, such as the sealing ring 6 and adhesive 5 used in combination, to further improve the sealing performance.

[0083] Please refer to Figures 9-12 , Figure 9 This is a schematic diagram of the structure when the transition connector 4 is connected to the housing 1 using the flange part 7. Figure 10 for Figure 9 The deformation scheme, Figure 11 for Figure 10 The deformation scheme, Figure 12 This is a structural schematic diagram of one specific embodiment of the flange part 7.

[0084] like Figure 9 As shown, in the third embodiment provided in this application, the computing device 202 may further include a flange 7 and a second sealing component 8. The flange 7 may be located on the outer wall of the transition connector 4, and the transition connector 4 may be assembled and connected to the housing 1 through the flange 7. The second sealing component 8 may be disposed between the flange 7 and the housing 1 to ensure the sealing performance between the flange 7 and the housing 1. The type of the second sealing component 8 may be the same as that of the first sealing component.

[0085] exist Figure 9 In one embodiment, the side of the housing 1 facing the flange 7 has a groove for installing the second seal 8, and the flange 7 is located on the outside of the housing 1. Figure 10 In one embodiment, the flange portion 7 has a groove on the side facing the housing 1 for installing the second seal 8, and the flange portion 7 is located on the outside of the housing 1. Alternatively, the flange portion 7 may be located on the inside of the housing 1.

[0086] The flange 7 and the transition connector 4 can be a one-piece structure, in which case there is no sealing problem between the flange 7 and the transition connector 4.

[0087] Alternatively, the flange 7 and the transition connector 4 can also be separately manufactured, separate structures, combined Figure 12 The flange 7 may be provided with a through hole 71, and the transition connector 4 may be sealed and inserted into the through hole 71. The transition connector 4 and the flange 7 can be sealed and assembled in various ways, such as bonding, welding, or sealing ring sealing. Taking sealing ring sealing as an example, the flange 7 can first be installed on the transition connector 4 by means of snap-fit ​​or screw connection, and then the gap between the outer wall of the transition connector 4 and the inner wall of the through hole 71 can be sealed with the sealing ring; in fact, the sealing ring can be the aforementioned second sealing component 8, that is, the second sealing component 8 can realize the sealing assembly between the flange 7 and the housing 1, and also realize the sealing assembly between the flange 7 and the transition connector 4.

[0088] The flange portion 7 and the transition connector 4 can have a one-to-one correspondence, in which case one flange portion 7 can correspond to the installation of one transition connector 4. Alternatively, the flange portion 7 and the transition connector 4 can also have a one-to-many relationship, in which case one flange portion 7 can correspond to the installation of multiple transition connectors 4. In this embodiment, the flange portion 7 can be provided with two or more through holes 71 for the installation and fixing of multiple transition connectors 4; combined with Figure 11 , Figure 11 A flange 7 is shown with two through holes 71, both of which can be used to insert transition connectors 4, thereby enabling the installation of the two transition connectors 4.

[0089] like Figure 12 As shown, the flange 7 can be provided with multiple mounting holes 72. In specific implementation, fasteners such as screws can be used to pass through the mounting holes 72 to fix them to the housing 1.

[0090] In this embodiment, the transition connector 4 can specifically be a flexible printed circuit board (FPC). The flexible printed circuit board has flexible deformation capabilities, which can better adapt to changes in the installation position of the connecting cable 3a. In actual use, it can have greater adjustability and meet the needs of flexible assembly. In particular, it can adapt to and absorb connection tolerances with external devices, which can significantly improve the convenience of connection, thereby enhancing the reliability of the connection and the stability of signal transmission.

[0091] Furthermore, the flexible circuit board, through its own flexible deformation, can effectively absorb the vibration and installation tension of the computing device 202 during actual use, thereby reducing the impact of vibration or installation tension on the sealing assembly of the transition connector 4.

[0092] In fact, the aforementioned transition connector 4 can also be a rigid circuit board.

[0093] Please refer to Figures 13-15 , Figure 13 A schematic diagram showing the structure in which the rigid circuit board is connected to the connecting device through the first flexible connector when the transition connector is a rigid circuit board; Figure 14 A schematic diagram of the structure of the rigid circuit board and the connecting device when the transition connector is a rigid circuit board; Figure 15 This is a diagram showing the connection structure between the floating mechanism and the connecting devices.

[0094] In some implementations, such as Figure 13 As shown, the connecting device can be fixedly installed inside the housing 1. In this case, if the transition connector 4 is a rigid circuit board, the computing device 202 can also be equipped with a first flexible connector 9. The first flexible connector 9 can specifically be a flexible circuit board, cable, etc., used for connecting the first electrical connection part of the connecting device and the rigid circuit board. Through the flexible transition of the first flexible connector 9, the defects caused by assembly errors and other factors that prevent the first electrical connection part and the connecting device from accurately aligning can be better adapted, and the connection reliability between the connecting device and the first electrical connection part can be improved, thereby improving the stability of signal transmission.

[0095] The connection method between the first flexible connector 9 and the first electrical connection part is not limited here, but is specifically related to the structural configuration of the first electrical connection part. Figure 13 In one embodiment, the first electrical connection part may be equipped with a gold finger 41. At this time, the first flexible connector 9 may be equipped with a connector 91. The connector 91 has a connection socket, and the first electrical connection part may be inserted into the connection socket of the connector 91.

[0096] In other implementations, such as Figure 14 and Figure 15 As shown, when the transition connector 4 is a rigid circuit board, a floating mechanism 2a can also be configured for the connector. Through the floating mechanism 2a, the position of the connector inside the housing 1 can be flexibly adjusted. This can also ensure the accurate connection between the connector and the first electrical connection part, and improve the reliability of the connection and the stability of signal transmission.

[0097] In detail, the connecting device may be provided with positioning holes 21, and the floating mechanism 2a may include positioning posts 2a-1. The number of positioning posts 2a-1 and positioning holes 21 may be consistent and they are assembled in a one-to-one correspondence. The floating mechanism 2 may also include a first elastic part 2a-2 and a second elastic part 2a-3, combined with... Figure 15The positioning post 2a-1 has a head, a first elastic part 2a-2 can be located between the connecting device and the head, and a second elastic part 2a-3 can be located between the housing 1 and the connecting device, thereby enabling the connecting device to float along the axial direction of the positioning post 2a-1. In each positioning post 2a-1, only some positioning posts 2a-1 may be equipped with the aforementioned first elastic part 2a-2 and second elastic part 2a-3, or all positioning posts 2a-1 may be equipped with the aforementioned first elastic part 2a-2 and second elastic part 2a-3.

[0098] The first elastic part 2a-2 and the second elastic component 2a-3 can be springs, or various forms of elastic elements such as bellows, elastic bodies made of elastic materials, as long as they can achieve the above-mentioned technical effects.

[0099] Furthermore, at least some of the positioning holes 21 may have a radial floating gap between them and the corresponding positioning post 2a-1. This allows the connecting device to be positioned in a plane perpendicular to the axial direction of the positioning post 2a-1, providing it with more position adjustment directions and better adapting to situations where direct connection is impossible due to assembly errors between the connecting device and the rigid circuit board.

[0100] Please continue to refer to this. Figure 14 In the connecting device and the rigid circuit board, one can be provided with an alignment sleeve 22, and the other can be provided with an alignment shaft 43, which can be inserted into the alignment sleeve 22. In this way, the reaction force generated by the floating mechanism 2a on the connecting device can be absorbed by the alignment shaft 43 and the alignment sleeve 22, which can prevent the force from acting directly on the connection position between the connecting device and the first electrical connection part 41, thereby reducing the force at the connection position between the connecting device and the first electrical connection part 41, which is more conducive to ensuring the reliability of the connection and the stability of signal transmission.

[0101] Taking the first electrical connection part with a gold finger 41 and the connecting device with a connector 91 as an example, the scheme of using the alignment sleeve 22 and the alignment shaft 43 for alignment and insertion can reduce the force on the first electrical connection part and the connector 91 at the insertion point, which is beneficial to protect the gold finger 41 and the connecting device 91, and can also extend the service life of both.

[0102] Because the connector is designed to float, the connector and other fixed devices or connection points inside the housing 11 can be connected using a second flexible connector 23 to accommodate the floating design of the connector. The second flexible connector 23 can specifically be a cable, a flexible circuit board, etc.

[0103] In practical applications, the signals transmitted between the computing device 202 and external devices may be high-speed signals. In this case, the connecting cable 3a is required to handle high-speed signals. Specifically, the differential pair rate of the connecting cable 3a can be 56 Gps or higher. Furthermore, the length of the connecting cable 3a can be relatively long. This allows for a very large transmission path ratio between the connecting cable 3a and the transition connector 4 in the signal transmission path between the connecting device and the external device, thereby reducing the losses caused by the introduction of the transition connector 4.

[0104] The signal transmission section of the circuit board can be made of conductive metal, such as copper. The conductive metal can be laid on the surface of the circuit board or embedded inside it. In this embodiment, the latter option is chosen to reduce the impact of the cooling medium on high-speed signal transmission within the conductive metal.

[0105] The number of conductive metals and the number of wire cores in the connecting cable 3a can be the same, and they can be electrically connected one-to-one to achieve signal transmission.

[0106] The structure of the transition connector 4 is not limited to the plate shape shown in the attached figure. It can also be a cylindrical shape or other structural forms. The specific form needs to be determined based on the actual application requirements.

[0107] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
