[0038] In the embodiments of this specification, a board bracket is used to protect the boards in the server. When the board is pushed into the board bracket from the insertion port, the first limiting arm bends outward from its initial position to ensure that the board is smoothly pushed in along the slide. When the board is pushed into the receiving cavity, the first limiting arm is no longer subjected to outward pressure and returns to its initial position to limit the board. When the board needs to be removed, applying force outward to the first limiting arm can release the limitation on the board, and then the board can be removed along the insertion port. This enables rapid insertion and removal of boards in servers with densely deployed components, improving the maintenance efficiency of boards in the server.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this specification, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0052] This application provides a board holder 100, such as Figure 1 As shown, it includes:

[0053] The main body 1 is arranged in the shape of a flat plate, and the size of the main body 1 is adapted to the board that needs to be placed in the board bracket 100;

[0054] Support edge 2 extends perpendicularly to both sides of the main body 1. The main body 1 and the support edge 2 form a receiving cavity 10 for accommodating the card. A slide 20 is formed on the support edge 2. The support edge 2 extends upward from both sides of the main body 1. The slide 20 formed on the support edge 2 corresponds to the receiving cavity 10. The slide 20 can provide support for the pushed-in card and limit the movement trajectory of the card pushed into the card holder 100.

[0055] The first limiting arm 3 is disposed on one side edge of the support edge 2. A plug-in port 11 is formed between the first limiting arms 3 on both sides of the support edge 2. The plug-in port 11 refers to the side of the board card being pushed into the board card bracket 100. It can be set according to actual needs.

[0056] The first limiting arm 3 bends outward from its initial position when subjected to outward pressure, and returns to its initial position when the outward pressure is removed.

[0057] The main body 1, supporting edge 2, and first limiting arm 3 can be integrally formed or separately formed by splicing or other methods. They can be made of materials with a certain degree of elasticity, such as plastic, and there are no restrictions on this. When outward pressure is applied to the first limiting arm 3, based on the elasticity between the first limiting arm 3 and the supporting edge 2, a certain degree of bending occurs from the initial position of the first limiting arm 3. This bending can elastically recover when the outward pressure is removed, that is, return to the initial position of the first limiting arm 3. The first limiting arms 3 correspond to the supporting edges 2 and are located on both sides of the main body 1, that is, there are two supporting edges 2 and two first limiting arms 3.

[0058] like Figure 2 As shown, when the board needs to be inserted into the board holder 100, the first limiting arm 3 can be abutted by the board to form outward pressure, or the operator can apply outward pressure, which forces the first limiting arm 3 to bend from its initial position, such as... Figure 2 As shown in section (A), the enlarged insertion port 11 allows the board to be pushed in more smoothly. When the board is pushed past the first limiting arm 3, the outward pressure applied to the first limiting arm 3 is released, and the first limiting arm 3 elastically returns to its initial position, i.e., returns to... Figure 2 As shown in section (B), the board is then electrically connected to the motherboard in the server. The board can be electrically connected to the motherboard through the board connector fixed in the board bracket 100, or it can be connected to the motherboard through a cable via the connector set on the board. The configuration can be set according to actual needs.

[0059] When the board is pushed into the receiving cavity 10 of the board holder 100, the edge of the first limiting arm 3 can abut against the board, thereby pushing the board into the slide 20 and finally confining it in the receiving cavity 10 of the board holder 100.

[0060] When it is necessary to remove a board from the board holder 100, an outward pressure can be applied to the first limiting arm 3 to bend it, thereby releasing the limitation of the first limiting arm 3 on the board, and then the board can be pushed out of the board holder 100. When the board is pushed out of the board holder 100, it returns to its initial position based on the elasticity of the first limiting arm 3.

[0061] By setting up the board bracket 100, the staff can first set up the board bracket 100 in the server, and then smoothly push the board in and take it out based on the first limiting arm 3. No additional devices such as screws or fixing posts are required during the process, making the insertion and removal of the board more convenient and improving the maintenance efficiency of the board in the server.

[0062] Optionally, the first limiting arm 3, such as Figure 3 As shown, it includes:

[0063] The elastic connecting part 30 is connected to the supporting edge 2, and the connection can be achieved by plugging or integral molding;

[0064] The first limiting part 31 is connected to the elastic connecting part 30 and extends away from the main body 1. This extension can refer to extending outward from the main body 1 along the direction of the supporting edge 2, that is, the supporting edge 2, the elastic connecting part 30, and the first limiting part 31 extend in a straight line. A limiting channel 32 corresponding to the slide 20 is formed in the first limiting part 31. The middle section of the limiting channel 32 is closer to the middle of the main body 1 than the two ends of the limiting channel 32.

[0065] Since the first limiting part 31 extends outward along the support edge 2, the limiting channel 32 formed in the middle of the first limiting part 31 can be understood as extending along the setting direction of the first limiting part 31. In the first limiting part 31, the upper wall 31A and the lower wall 31B are protruding, and the limiting channel 32 is formed between the upper wall 31A and the lower wall 31B. The limiting channel 32 is used to limit the height of the board in the vertical direction when it is pushed in, so as to prevent the board from detaching from the board bracket 100 during the pushing process.

[0066] The limiting channel 32 is strip-shaped, with its middle section and two ends referring to the middle and two ends relative to its extension direction. To allow the board to be smoothly pushed into the board holder 100 in some cases, the board needs to be pushed more smoothly into the front end of the limiting channel 32. As the board is pushed in, it needs to abut against the middle section of the limiting channel 32 to achieve bending of the first limiting arm 3. After the board is pushed into the board holder 100, the rear end of the limiting channel 32 needs to limit the board. Therefore, the front and rear ends of the limiting channel 32 need to have larger dimensions, while the middle section of the limiting channel 32 has a smaller dimension. This dimension refers to the dimension between the limiting channels 32 in the first limiting arms 3 on both sides; that is, the dimension between the middle sections of the first limiting arms 3 on both sides is smaller than the dimensions of the front and rear ends of the first limiting arms 3 on both sides. The middle part of the main body 1 refers to the centerline in the length direction, which can be understood as the extension direction of the support edge 2.

[0067] With the aforementioned limiting channel 32, due to the increased space, an abutment wall 32A can be formed between the middle section and the rear section to limit the board pushed into the board bracket 100.

[0068] Specifically, such as Figure 4 As shown, the limiting channel 32 is formed in sequence with a limiting segment 32B, an abutting segment 32C and a receiving segment 32D in the direction away from the main body 1. The abutting segment 32C is closer to the middle of the main body 1 than the receiving segment 32D, and the limiting segment 32B is farther away from the middle of the main body 1 than the receiving segment 32C.

[0069] In other words, the size between the abutting sections 32C of the limiting channels 32 on both sides is the smallest, the size between the receiving sections 32D of the limiting channels 32 on both sides is larger than the size between the abutting sections 32C of the limiting channels 32 on both sides, and the size between the limiting sections 32B of the limiting channels 32 on both sides is not smaller than the size between the receiving sections 32D of the limiting channels 32 on both sides, thereby ensuring that the board is smoothly pushed in along the limiting channels 32, pushing the bending of the first limiting arm 3 outward and engaging the board pushed into the receiving cavity 10.

[0070] Optionally, the first limiting arm 3, such as Figure 5 As shown, it also includes:

[0071] The guide portion 33 protrudes from the limiting section 32B and has a guide surface 33A facing the limiting channel 32.

[0072] The guide portion 33 forms a limiting channel 32, and the protrusion forms a partial obscuring of the limiting channel 32 so that the plate in the limiting channel 32 can be guided to a more suitable position so that it can smoothly enter the slide 20 of the support edge 2 during subsequent pushing.

[0073] The guide portion 33 can be configured as a ramped protrusion, referred to as guide surface 33A, which faces the limiting channel 32. When the plate abuts against guide surface 33A, it moves towards either the lower wall 31B or the upper wall 31A due to the slope of guide surface 33A. The configuration of the guide portion 33 and guide surface 33A can be customized according to actual needs, allowing for unrestricted movement towards either the lower wall 31B or the upper wall 31A.

[0074] Optionally, a guide groove 21 is also formed on the support edge 2. The first end 21A of the guide groove 21 is connected to the slide rail 20, and the second end 21B of the guide groove 21 faces the insertion port 11 and is larger in size than the first end 21A of the guide groove 21.

[0075] The guide groove 21 is roughly trapezoidal, with a smaller top edge and a larger bottom edge. One side of the top edge is connected to the slide rail 20, and one side of the bottom edge is close to the insertion / removal port 11. When the board is pushed to the edge of the slide rail 20 through the limiting channel 32, the side of the guide groove 21 can guide the board into the slide rail 20, so that it can be further pushed into the receiving cavity 10, thereby improving the reliability of blind insertion of the board.

[0076] Optionally, the board holder 100, such as Figure 1 As shown, it also includes:

[0077] The second limiting arm 4 is formed on the edge of the main body 1 and corresponds to the insertion port 11;

[0078] The second limiting arm 4 includes:

[0079] Extension 40 is connected to the main body 1;

[0080] The second limiting part 41 is raised from the extension part 40 toward the insertion port 11.

[0081] The second limiting arm 4 is curved and has a certain slope. When the board is pushed in from the insertion port 11, the second limiting arm 4 located below the insertion port 11 can provide some support for the board and prevent the board from falling and being damaged.

[0082] When the board is removed from the board holder 100, the second limiting part 41 of the second limiting arm 4 can act as a stop to prevent the board from slipping out of the board holder 100 and causing damage.

[0083] Since the second limiting arm 4 can also have a certain degree of elasticity, the height of its second limiting part 41 can also be set to partially cover the plug-in port 11. The deformation of the extension part 40 causes the board to bend downward when it is pushed in, so that the second limiting part 41 avoids the plug-in port 11.

[0084] Correspondingly, this application also provides a board module 200, such as Figure 6 As shown, it includes:

[0085] The module tray 201 can be formed of materials such as metal or plastic. The module tray 201 is plate-shaped and its arrangement is similar to that of the board bracket 100.

[0086] The board bracket 100 of any of the above-mentioned items is fixed to the module tray 201. The board bracket 100 can be fixed by means of hooks and buckles, gourd holes and mushroom heads or screws and screw holes.

[0087] The board 202 is inserted into the board bracket 100 through the insertion port 11 and is accommodated in the receiving cavity 10 of the board bracket 100.

[0088] The board module 200 can be installed in a server. During installation, the module tray 201 is first fixed to the server's chassis or the server's motherboard. Then, the board bracket 100 that has not been pushed into the board 202 or the board bracket 100 that has been pushed into the board 202 is connected to the module tray 201 to install the board module 200.

[0089] It should be noted that the assembly process of the board module 200 may differ depending on the connection method between the board bracket 100 and the module tray 201. For example, if the board bracket 100 and the module tray 201 are fixed with screws and screw holes, the board bracket 100 and the module tray 201 must be connected first, and then the board 202 must be pushed in. This is because the screws and screw holes are located on the underside of the board 202; if the board 202 is pushed into the board bracket 100 beforehand, the connection between the board bracket 100 and the module tray 201 will not be possible. If hooks and clips or gourd holes and mushroom heads are used, the board 202 can be pushed into the board bracket 100 first, and then the board bracket 100 and the module tray 201 can be connected. The specific method can be set according to actual needs and is not limited.

[0090] The method of pushing the board 202 into the board bracket 100 and the method of removing the board 202 from the board bracket 100 are the same as those described above, and will not be described again.

[0091] Optional, board module 200, such as Figure 6 As shown, it also includes:

[0092] The board connector 203 is located on the side of the board bracket 100 away from the plug-in port 11 and is electrically connected to the board 202.

[0093] The board 202 can have gold fingers 202A formed on it. The connection between the board 202 and the motherboard of the server can be achieved through the board connector 203. That is, the board connector 203 is provided with pins corresponding to the gold fingers 202A. These pins are led out through the cable of the board connector 203 and plugged into the motherboard.

[0094] When the board 202 is pushed into the board bracket 100, the gold fingers 201A and the board connector 203 are aligned through the limiting channel 32 and the slide 20, thereby connecting the motherboard to the board 202 through the board connector 203.

[0095] The board connector 203 can be fixed to the board bracket 100 by snap-fit ​​or screw-fit, without limitation.

[0096] Optional, such as Figure 1 As shown, a support column 12 is also formed on the main body 1 of the board bracket 100. The support column 12 can be integrally formed with the board bracket 100, or it can be fixed to the main body 1 by means of adhesive or the like.

[0097] The support column 12 is located below the board connector 203.

[0098] Since a certain downward (i.e., toward the board bracket 100) external force needs to be applied to the board connector 203 when it is fixed to the board bracket 100, and since the board connector 203 is strip-shaped, the downward external force may cause the board connector 203 to deform, thereby reducing the reliability of the subsequent board 202 being pushed into the board connector 203. Therefore, setting a support column 12 below the board connector 203 to support the board connector 203 can reduce the possibility of deformation caused when installing the board connector 203 and improve the reliability of the connection between the board 202 and the board connector 203.

[0099] Optionally, the board holder 100, such as Figure 1 , 7 As shown, it also includes:

[0100] A fixed spring arm 5 is formed on the edge of the main body 1 of the board bracket 100, corresponding to the plug-in port 11. A gourd hole 50 is formed on the fixed spring arm 5. The setting direction of the gourd hole 50 can be set according to actual needs. For example, the small hole in the gourd hole 50 is close to the main body 1, and the large hole in the gourd hole 50 is far away from the main body 1, or the opposite position can be set. The setting of the gourd hole 50 is based on the installation direction of the board bracket 100 and the module tray 201.

[0101] A snap-fit ​​groove 13 is formed on the side of the main body 1 away from the insertion port 11;

[0102] The module tray 201 has a mushroom head 204 and a snap-fit ​​protrusion 205. The mushroom head 204 cooperates with the gourd hole 50, and the snap-fit ​​protrusion 205 cooperates with the snap-fit ​​groove 13.

[0103] Both the gourd hole 50 and the snap-fit ​​groove 13 can be formed with a slope in the direction of installation. This slope can provide a downward thrust to the board bracket 100 when the mushroom head 204 and the snap-fit ​​protrusion 205 cooperate with the gourd hole 50 and the snap-fit ​​groove 13, so as to ensure that the board bracket 100 can be firmly fixed on the module tray 201. Through the cooperation between the mushroom head 204 and the gourd hole 50 and the cooperation between the snap-fit ​​protrusion 205 and the snap-fit ​​groove 13, on the one hand, the connection between the board bracket 100 and the module tray 201 can be made more efficient, and on the other hand, the electrical connection between the board 202 and the board connector 203 can be realized and then the board bracket 100 containing the board 202 and the module tray 201 can be connected as a whole, reducing the installation operation in the server and simplifying the installation process of the board module 200.

[0104] Correspondingly, this application also provides a server 300, such as Figure 8 As shown, it includes:

[0105] Motherboard 301; and

[0106] The board module 200 of any of the above, wherein the board 202 in the board module 200 is electrically connected to the motherboard 301.

[0107] In the embodiments of this specification, a board bracket is used to protect the boards in the server. When the board is pushed into the board bracket from the insertion port, the first limiting arm bends outward from its initial position to ensure that the board is smoothly pushed in along the slide. When the board is pushed into the receiving cavity, the first limiting arm is no longer subjected to outward pressure and returns to its initial position to limit the board. When the board needs to be removed, applying force outward to the first limiting arm can release the limitation on the board, and then the board can be removed along the insertion port. This enables rapid insertion and removal of boards in servers with densely deployed components, improving the maintenance efficiency of boards in the server.

[0108] This board module 200 can be used to implement functions such as storage expansion and computing expansion. It can be configured according to actual needs, and there are no restrictions on it.

[0109] Other embodiments of this specification will readily occur to those skilled in the art upon consideration of the specification and practice of the invention claimed herein.
