Description

Technical Field

[0001] The present invention relates to the technical field of network card modules, and in particular to a hot-plug network card module and a server. Background Art

[0002] At least one network card is required in the server to provide network connection and data transmission functions, as well as multiple functions such as data processing, load balancing, network management, network security, and virtualization support. PCIe module is a commonly used functional module for servers, usually consisting of a PCIe card, a function expansion card (riser card), and a bracket. The PCIe card can be a card with any function that complies with the PCIe specification.

[0003] The PCIe module in the related technology fixes the function expansion card on the outside of the bracket, and the PCIe card passes through the hole on the bracket to be plugged into the function expansion card, and only relies on simple plugging with the function expansion card to achieve fixation of the PCIe card. During frequent plugging and unplugging or use of the PCIe module, the connection between the PCIe card and the function expansion card can easily become loose due to external force or vibration, which may cause the PCIe card to accidentally fall off, seriously affecting the stability of the system and the security of the data. Summary of the invention

[0006] Beneficial effects: through the setting of the installation port, the network card can be set in the installation cavity and plugged into the function expansion card; through the setting of the baffle, the network card can be limited and fixed, thereby ensuring the stability of the network card installation; during the frequent plugging and unplugging or use of the hot-swappable network card module, the stability of the connection between the network card and the function expansion card is enhanced, which helps to enhance the stability of the system and the security of the data; since the function expansion card and the network card are both set in the installation cavity, during the plugging and unplugging of the hot-swappable network card module, the function expansion card and the network card can also be protected to avoid scratches and damage to the function expansion card or the network card.

[0007] In an optional embodiment, a connecting portion is protruded from one side of the second side wall of the installation cavity along the first direction, and the hinged end of the baffle is connected to the connecting portion; the second side wall is the side wall of the installation cavity along the second direction; the second direction is the length direction of the bracket; a pressing spring is provided on the baffle, and the pressing spring is protruded on the side of the hinged end close to the second side wall; a baffle is protruded from one side of the network card along the second direction, and in the first direction, the distance between the baffle and the baffle is greater than the distance between the network card and the baffle; when the connecting end of the baffle is connected to the first side wall, the baffle abuts against the pressing spring and the second side wall on both sides along the first direction respectively; and the pressing spring abuts against the network card on the side along the second direction.

[0008] Beneficial effect: through the setting of the card pressing spring piece and the baffle, when the baffle is closed, the two sides of the baffle along the first direction are respectively in contact with the card pressing spring piece and the second side wall, during the operation of the server or the process of plugging and unplugging the hot-swappable network card module, the stability of the network card installed in the installation cavity is ensured, and the vibration and slight displacement caused by system operation or manual operation are effectively resisted, which ensures that the network card can always be stably connected to the function expansion card; and because in the first direction, the distance between the baffle and the baffle is greater than the distance between the network card and the baffle, when the baffle is closed, the card pressing spring piece can be located in the gap between the baffle and the second side wall, making the structure inside the installation cavity more compact.

[0009] In an optional embodiment, a first limiting groove is provided on the blocking piece, and a spring claw is protruded from one side of the card pressing spring piece close to the blocking piece, and the spring claw is suitable for being clamped in the first limiting groove.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0059] Combine the following Figures 1 to 20 , describing an embodiment of the present invention.

[0060] According to an embodiment of the present invention, on the one hand, a hot-swappable network card module is provided, including a bracket 1, a function expansion card 2 and a network card 3; an installation cavity 101 is provided inside the bracket 1, a installation port is provided on the first side wall 102 of the installation cavity 101, and a baffle 103 is provided at the position where the installation port is located, the hinged end of the baffle 103 is hinged to the first side wall 102, and the connecting end is suitable for being detachably connected to the first side wall 102; the first side wall 102 is the side wall of the installation cavity 101 along the first direction; the first direction is the width direction of the bracket 1; the function expansion card 2 is arranged in the installation cavity 101, and is arranged opposite to the installation port along the first direction; the network card 3 is arranged in the installation cavity 101 through the installation port along the first direction, and is plugged and connected with the function expansion card 2.

[0061] By setting the installation opening, the network card 3 can be set in the installation cavity 101 and plugged into the function expansion card 2. By setting the baffle 103, the network card 3 can be limited and fixed, thereby ensuring the stability of the installation of the network card 3. During the frequent plugging and unplugging or use of the hot-swappable network card module, the stability of the connection between the network card 3 and the function expansion card 2 is enhanced, which helps to enhance the stability of the system and the security of the data. Since the function expansion card 2 and the network card 3 are both set in the installation cavity 101, during the plugging and unplugging of the hot-swappable network card module, the function expansion card 2 and the network card 3 can also be protected to avoid scratches and damage to the function expansion card 2 or the network card 3.

[0062] In a specific implementation, the network card 3 is a PCIe card.

[0063] In a specific implementation, a standard PCIe slot is provided on one side of the function expansion card 2 close to the installation port, and the gold finger on the network card 3 is directly plugged and connected to the standard PCIe slot.

[0064] In a specific embodiment, each side wall of the installation cavity 101 is provided with a heat dissipation hole to ensure the heat dissipation effect of the network card 3. Preferably, the top of the installation cavity 101 is open, which ensures the fixing effect of the network card 3 and enhances the heat dissipation effect of the network card 3.

[0065] In a specific implementation, the size and shape of the network card 3 are single-width and double-width types. The double-width network card 3 is usually an intelligent network card 3, which provides significant advantages and enhanced functions in terms of hardware offloading capabilities, programmability, storage acceleration, security functions, high performance and low latency, and unloading workloads compared to the single-width network card 3. These functions make the double-width network card 3 particularly advantageous in data-intensive scenarios, virtualized environments, machine learning, cloud services and other fields. The hot-swappable network card module in the present invention can support the installation of both single-width network cards 3 and double-width network cards 3, and has a wide range of applications. Preferably, when installing a single-width network card 3, an L-shaped baffle 301 is provided in the installation cavity 101 to enhance the stability of the installation of the single-width network card 3.

[0067] By setting the card pressing spring piece 1031 and the baffle 301, when the baffle 103 is closed, the baffle 301 abuts against the card pressing spring piece 1031 and the second side wall 104 on both sides along the first direction respectively, during the operation of the server or the process of plugging and unplugging the hot-swappable network card module, the stability of the network card 3 installed in the installation cavity 101 is ensured, and the vibration and small displacement caused by system operation or manual operation are effectively resisted, which ensures that the network card 3 can always be stably connected to the function expansion card 2; and because in the first direction, the distance between the baffle 301 and the baffle 103 is greater than the distance between the network card 3 and the baffle 103, therefore, when the baffle 103 is closed, the card pressing spring piece 1031 can be located in the gap between the baffle 103 and the second side wall 104, so that the structure inside the installation cavity 101 is more compact.

[0068] Specifically, the card pressing spring 1031 is made of stainless steel.

[0069] In one embodiment, a first limiting groove 3011 is provided on the blocking piece 301 , and a spring claw 10311 is protruded from one side of the pressing spring piece 1031 close to the blocking piece 301 , and the spring claw 10311 is suitable for being clamped in the first limiting groove 3011 .

Specifically, the fixed shell is a plastic shell formed by injection molding.

[0092] In one embodiment, a limiting column 1101 is provided on the connecting plate 11, and a fixing hole 1201 is provided on the fixing bracket 12. The limiting column 1101 is suitable for passing through the fixing hole 1201, and has a sliding position that slides with the fixing hole 1201, and a snap-fit ​​position that snaps with the fixing hole 1201; a first connecting hole 1102 is also provided on the connecting plate 11 of the chassis 5, and the first connecting hole 1102 is spaced apart from the limiting column 1101; the fixing bracket 12 is also provided with a second connecting hole and a telescopic The plunger 13, the second connecting hole and the fixing hole 1201 are arranged at intervals; the telescopic plunger 13 corresponds to the position where the second connecting hole is located, and the telescopic plunger 13 has a fixed position that passes through the second connecting hole and the first connecting hole 1102 in sequence, and a separated position that is separated from the second connecting hole; when the limiting column 1101 is in the sliding position, the telescopic plunger 13 is in the separated position; when the limiting column 1101 is in the clamping position, the telescopic plunger 13 is in the fixed position.

[0093] By setting the limiting column 1101 and the fixing hole 1201, accurate positioning between the fixed bracket 12 and the connecting plate 11 is achieved; because when the limiting column 1101 is in the sliding position, the telescopic plunger 13 is in the separation position, which helps to achieve sliding cooperation between the limiting column 1101 and the fixing hole 1201; when the limiting column 1101 is in the clamping position, the telescopic plunger 13 is in the fixed position, and through cooperation with the telescopic column, it is ensured that the limiting column 1101 can always be in the clamping position, which can prevent the fixed bracket 12 from shifting and ensure the stability of the installation of the fixed bracket 12; and through the setting of the telescopic plunger 13, tool-free disassembly and assembly between the fixed bracket 12 and the connecting plate 11 is achieved, thereby improving the efficiency of installation and disassembly of the fixed bracket 12.

[0097] Specifically, the fixing hole 1201 includes a sliding channel and a limiting channel arranged in sequence along the second direction; towards the side close to the limiting channel, the distance between the two side walls of the sliding channel arranged oppositely along the first direction gradually decreases; when the limiting column 1101 is in the sliding position, the limiting column 1101 is inserted into the sliding channel and slides with the sliding channel; when the limiting column 1101 is in the clamping position, the limiting column 1101 is inserted into the limiting channel and clamps with the limiting channel. Since the distance between the two side walls of the sliding channel arranged oppositely along the first direction gradually decreases towards the side close to the limiting channel, a gradually shrinking space structure is formed, so the moving path of the limiting column 1101 can be limited, the limiting column 1101 plays a guiding role, ensures the accuracy of its movement direction, and helps the limiting column 1101 slide to the position where the limiting channel is located.

[0099] Since the fixed body 1301 is located on the side of the fixed bracket 12 away from the connecting plate 11, it is ensured that when the telescopic plunger 13 is in the fixed position, the fixed bracket 12 can be tightly abutted against the connecting plate 11, saving installation space; and since the outer diameter of the limiting section 13021 is larger than the diameter of the third connecting hole, it can be ensured that the limiting end can always be located on the side of the fixed body 1301 away from the fixed bracket 12; through the setting of the fixed body 1301, the elastic member and the telescopic rod 1302 can be connected and fixed; through the cooperation of the telescopic rod 1302 and the elastic member, it is helpful to achieve tool-free disassembly and assembly between the fixed bracket 12 and the connecting plate 11 through the telescopic plunger 13.

[0100] In a specific embodiment, when no external force is applied to the telescopic rod 1302, the fixed section 13022 protrudes from the fixed bracket 12; when the fixed bracket 12 needs to be installed, the limit column 1101 is inserted into the sliding channel and slides with the sliding channel. At this time, under the abutment of the connecting plate 11, the telescopic plunger 13 moves to the side away from the connecting plate 11 until the limit column 1101 slides to the clamping position, and the telescopic plunger 13 slides to the first connecting hole 1102. When the fixing bracket 12 needs to be disassembled, the limiting section 13021 is pulled toward the side away from the fixing bracket 12, and the fixing section 13022 is separated from the first connecting hole 1102 under the drive of the limiting section 13021, and then the limiting column 1101 is moved to the sliding channel of the fixing hole 1201, and then the fixing bracket 12 can be disassembled.
