Description

Technical Field

[0001] The embodiments of the present application relate to the field of computers, and in particular, to a server expansion card mounting rack and a server. Background Art

[0002] The fastest bandwidth of the current PCIe card (peripheral component interconnect express, a high-speed serial computer expansion bus standard expansion card) is X16, with a total of 164 pins. The insertion force of each pair of pins is 1.15N, so the X16 card requires 94.3N. When assembling and operating a single card, you may not feel that the force is large, but when assembling and operating PCIe cards in large quantities, the staff will be time-consuming and laborious to plug and unplug for a long time, and it is very easy to get tired and injured. In addition, the demand for PCIe bandwidth is increasing, and double-row pin connectors have begun to appear, with a total of 428 pins. The plug-in force will increase significantly, making it more difficult to plug and unplug with one hand and plug and unplug in large quantities. Summary of the invention

[0003] The embodiments of the present application provide a server expansion card mounting rack and a server, so as to at least solve the problem of time-consuming and labor-intensive large-scale assembly and operation and maintenance of PCIe cards in the related art.

[0004] According to one aspect of the present application, a server expansion card mounting rack is provided, comprising: a tray, the tray having a plug-in end for plugging in an expansion card; a rotating rack, the rotating rack being rotatably connected to the tray, the rotating rack having a connecting end rotatably connected to the tray, a pushing end for abutting and pushing the expansion card, and an operating end for operation, the pushing end being located between the connecting end and the operating end, and the operating end pushing the expansion card to be plugged into the plug-in end when the rotating rack rotates.

[0005] Further, along the length direction of the rotating frame, the connecting end and the operating end are located at two ends of the rotating frame, and the pushing end is located in the middle area of ​​the rotating frame.

[0006] Furthermore, the rotating frame and the plug-in end are located on opposite sides of the tray.

[0007] Furthermore, a side of the rotating frame facing the plug-in end has a protrusion, and an end of the protrusion serves as a pushing end.

[0008] Furthermore, the server expansion card mounting frame also includes a sliding frame, which is movably arranged on the tray, and the sliding frame is drivingly connected to the rotating frame and moves driven by the rotating frame.

[0009] Furthermore, the sliding frame has a stopper on one side facing the plug-in end, and the stopper abuts against the expansion card. When the sliding frame moves away from the plug-in end driven by the rotating frame, the stopper drives the expansion card to disengage from the plug-in end.

[0010] Furthermore, the server expansion card mounting frame also includes a locking mechanism, which is connected to the rotating frame, and the sliding frame has a locking end. The locking mechanism and the locking end can be docked and detached. When the locking mechanism is docked with the locking end, the rotating frame drives the sliding frame to move. When the locking mechanism is separated from the locking end, the rotating frame rotates relative to the sliding frame.

[0011] Furthermore, the locking mechanism includes: a bracket, which is movably connected to the rotating frame along the length direction of the rotating frame, and the bracket has a locking hook portion, and the locking hook portion has a guiding inclined surface on the side facing the plug-in end. When the locking mechanism is docked with the locking end, the locking hook portion and the locking end are limitedly matched, and when the rotating frame rotates relative to the sliding frame and approaches the sliding frame, the locking end abuts against the guiding inclined surface, and the locking end pushes the locking hook portion to move and makes the locking hook portion pass the locking end; a reset member, which abuts against the locking hook portion and provides a reset force for the locking hook portion to move in a direction close to the locking end.

[0012] Furthermore, the locking mechanism has a rotating trajectory when driven by the rotating frame, and the locking end has a sliding trajectory when driven by the sliding frame. The rotating trajectory and the sliding trajectory are arranged to intersect each other. After the rotating frame drives the sliding frame to move a predetermined distance away from the plug-in end, the locking mechanism separates from the locking end, and the rotating frame idles relative to the sliding frame.

[0013] Furthermore, the tray has a plurality of limiting portions, which enclose a receiving area for receiving the expansion card, and the sliding frame is located in the receiving area.

[0014] Furthermore, the limiting portion includes: a first limiting protrusion, the first limiting protrusion is located on the surface of the tray and protrudes toward the direction of the sliding frame, there are multiple first limiting protrusions, and the first limiting protrusions are arranged on the opposite sides of the sliding frame, and the expansion card is supported on the first limiting protrusions; a second limiting protrusion, the second limiting protrusion is located on the opposite sides of the accommodating area, and can abut against the side of the expansion card.

[0015] Furthermore, one of the sliding frame and the tray has an elastic protrusion, and the other of the sliding frame and the tray has a through hole. When the expansion card is plugged into the plug-in end, the elastic protrusion is aligned with the through hole, and the elastic protrusion extends into the through hole. When the rotating frame drives the sliding frame away from the plug-in end, the elastic protrusion exits the through hole.

[0016] Furthermore, the rotating frame has a spherical protrusion, and the tray has a through hole. When the rotating frame pushes the expansion card to be plugged into the plug-in end, the spherical protrusion is located in the through hole.

[0017] Furthermore, a side of the rotating frame facing the plug-in end has a protrusion, and an end of the protrusion serves as a pushing end. Along the length direction of the rotating frame, the connection end and the operating end are located at both ends of the rotating frame, and the protrusion is located in the middle area of ​​the rotating frame; the server expansion card installation frame also includes a sliding frame, which is movably arranged on the tray, and the sliding frame is drivingly connected to the rotating frame. When the rotating frame rotates, it drives the sliding frame to move along the plug-in direction of the expansion card. The side of the sliding frame facing the plug-in end has a bent stopper, and the stopper is located on the moving path of the expansion card. When the sliding frame moves in a direction away from the plug-in end under the drive of the rotating frame, the stopper drives the expansion card to disengage from the plug-in end; the server expansion card installation frame also includes a locking mechanism, and the locking mechanism has a hook-shaped locking hook portion. The sliding frame has a locking end, and the locking hook part and the locking end can be docked and detachably matched, so that the rotating frame drives the sliding frame to move or the rotating frame rotates relative to the sliding frame. The locking hook part has a rotating trajectory line under the drive of the rotating frame, and the locking end has a sliding trajectory line under the drive of the sliding frame, and the rotating trajectory line and the sliding trajectory line are arranged to intersect; when the rotating frame rotates in the direction close to the plug-in end, the locking hook part and the locking end are docked and matched, and the rotating frame drives the sliding frame to move in the direction close to the plug-in end; when the rotating frame rotates in the direction away from the plug-in end, the rotating frame drives the sliding frame to move in the direction away from the plug-in end through the locking hook part, and the sliding frame drives the expansion card to disengage from the plug-in end. After the sliding frame moves a predetermined distance, the locking hook part separates from the locking end, and the rotating frame rotates relative to the sliding frame.

[0018] According to another aspect of the present application, a server is provided, including an expansion card and the above-mentioned server expansion card mounting bracket, wherein the expansion card is detachably plugged into a plug-in end of the server expansion card mounting bracket.

[0019] The technical solution of the present application is provided with a rotating frame, and the rotating frame has three action points, namely a connecting end, a pushing end and an operating end, wherein the connecting end is an end connected to the tray, the pushing end is an end that pushes the expansion card to be plugged into the plug-in end, and the operating end is an end where the staff applies force. By arranging the pushing end between the connecting end and the operating end, the distance between the pushing end and the connecting end is made smaller than the distance between the operating end and the connecting end. In this way, the lever principle is utilized to make it easier for the staff to operate the operating end, and the force required to be applied can be greatly reduced during large-scale assembly and operation and maintenance, thereby reducing labor intensity and improving plug-in and unplug efficiency.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0038] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0039] In order to solve the problem of time-consuming and labor-intensive mass assembly and operation and maintenance of PCIe cards in the related art, an embodiment of the present application provides a server expansion card mounting rack and a server.

[0040] like Figures 1 to 15 A server expansion card installation rack shown in the figure includes a tray 10 and a rotating frame 20, the tray 10 has a plug-in end 11 for plugging in an expansion card 50; the rotating frame 20 is rotatably connected to the tray 10, and the rotating frame 20 has a connecting end 21 rotatably connected to the tray 10, a pushing end 22 for abutting and pushing the expansion card 50, and an operating end 23 for operation, the pushing end 22 is located between the connecting end 21 and the operating end 23, and when the rotating frame 20 rotates, the operating end 23 pushes the expansion card 50 to be plugged into the plug-in end 11.

[0041] In this embodiment, a rotating frame 20 is provided, and the rotating frame 20 has three action points, namely a connecting end 21, a pushing end 22 and an operating end 23, wherein the connecting end 21 is an end connected to the tray 10, the pushing end 22 is an end that pushes the expansion card 50 to be plugged into the plug-in end 11, and the operating end 23 is an end where the staff applies force. By arranging the pushing end 22 between the connecting end 21 and the operating end 23, the distance between the pushing end 22 and the connecting end 21 is smaller than the distance between the operating end 23 and the connecting end 21. In this way, the lever principle is used to make it easier for the staff to operate the operating end 23, and the force required to be applied can be greatly reduced during large-scale assembly and operation and maintenance, thereby reducing labor intensity and improving plug-in and unplug efficiency.

[0042] like Figure 5 As shown, according to the calculation based on the moment balance, it can be obtained that F1*L1=F2*L2. Since the force arm L1 of the operating end 23 is larger than the force arm L2 of the pushing end 22, the force F1 required to be applied by the operating end 23 is smaller than the force F2 required to be applied by the pushing end 22. In this way, the force required to be applied by the staff is smaller than the force required to insert the expansion card 50 into the plug-in end 11, thereby achieving the functional effect of labor-saving card insertion.

[0043] In this embodiment, along the length direction of the rotating frame 20, the connecting end 21 and the operating end 23 are located at both ends of the rotating frame 20, and the pushing end 22 is located in the middle area of ​​the rotating frame 20. In other words, the two ends of the rotating frame 20 are the connecting end 21 and the operating end 23, respectively, and the pushing end 22 is located in the middle position, so that the distance between the operating end 23 and the connecting end 21 can be as long as possible, which is conducive to reducing the force that the staff needs to apply and improving the labor-saving effect.

[0044] In this embodiment, the rotating frame 20 and the plug-in end 11 are located on opposite sides of the tray 10. In this way, the push end 22 of the rotating frame 20 can better act on the side of the expansion card 50 away from the plug-in end 11, so that the force of the push end 22 on the expansion card 50 is basically all used to push the expansion card 50 into the plug-in end 11, thereby improving the effect of applying force to insert the card. Of course, the specific setting position of the rotating frame 20 can also be adjusted as needed, as long as it can ensure that the push end 22 can drive the expansion card 50 to be plugged into the plug-in end 11 when acting on the expansion card 50.

[0045] like Figures 1 to 6As shown, in this embodiment, considering that the rotating frame 20 is arranged in a rotating manner, and the side of the expansion card 50 is a plane, the side of the rotating frame 20 and the side of the expansion card 50 are not parallel, but have a certain angle, so in this embodiment, a protrusion is provided on the side of the rotating frame 20 facing the plug-in end 11, and the protrusion protrudes a distance toward the plug-in end 11, and the end of the protrusion serves as a pushing end 22, so that the end of the protrusion can stably abut against the side of the expansion card 50 when the rotating frame 20 rotates, thereby pushing the expansion card 50 to be plugged into the plug-in end 11. The protruding distance of the protrusion can be long, so that the protrusion has priority over the abutment between the side of the rotating frame 20 and the expansion card 50, avoiding the abutment between the side of the rotating frame 20 and the corner of the expansion card 50, resulting in the displacement of the expansion card 50. Preferably, the contact position between the protrusion and the expansion card 50 is approximately located at the middle position of the side of the expansion card 50, so that the pushing force of the protrusion on the expansion card 50 can make the expansion card 50 keep its own state close to the plug end 11 until it is inserted into the plug end 11.

[0046] In the present embodiment, the server expansion card installation frame also includes a sliding frame 30, which is movably arranged on the tray 10, and the sliding frame 30 is drivingly connected to the rotating frame 20, and moves under the drive of the rotating frame 20. There is no direct connection between the sliding frame 30 and the expansion card 50 of the present embodiment. Since the process of plugging in the expansion card 50 only requires the protrusion on the rotating frame 20 to push, the sliding frame 30 does not need to play a role in the process of plugging in the expansion card 50. Since the protrusion can only play a role in pushing the expansion card 50, it cannot pull the expansion card 50 to move in the opposite direction. Therefore, the protrusion of the rotating frame 20 mainly plays a role in pushing the card. If it is only necessary to save effort when plugging in the expansion card 50, the sliding frame 30 can be omitted. However, the present embodiment not only saves effort when inserting the card, but also saves effort when pulling it out. Therefore, the sliding frame 30 is provided in the present embodiment. Fig.10 , Fig.12 and Fig.13 As shown, the sliding frame 30 of the present embodiment has a stop portion 31 on the side facing the plug-in end 11. The stop portion 31 of the present embodiment is formed by bending a section of the surface of the sliding frame 30 toward the direction of the expansion card 50. In this way, the stop portion 31 and the sliding frame 30 are an integrated structure, and the stop portion 31 is located on the movement path of the expansion card 50. The stop portion 31 can abut against the side of the expansion card 50 facing the plug-in end 11. In this way, when the expansion card 50 needs to be pulled out, the rotating frame 20 rotates in the opposite direction and drives the sliding frame 30 to move in the direction away from the plug-in end 11. At this time, the stop portion 31 abuts against the expansion card 50. With the movement of the sliding frame 30, the stop portion 31 can drive the expansion card 50 to move in the direction away from the plug-in end 11, thereby making the expansion card 50 disengaged from the plug-in end 11, thereby achieving the effect of pulling out.

[0047] like Figure 4 As shown, when removing, the calculation based on the moment balance can obtain F1*L1=F2*L2. Since L1 is larger than L2, the force F1 is smaller than the force F2, thereby achieving a labor-saving effect. In this way, through the cooperation between the rotating frame 20 and the sliding frame 30, the expansion card 50 is affected by the rotating frame 20 and the sliding frame 30 during the two processes of inserting and removing the expansion card 50, respectively. The design of the rotating frame 20 reduces the force that the staff needs to apply at the operating end 23, thereby achieving a labor-saving effect in the entire process of inserting and removing the expansion card 50.

[0048] Preferably, in order to ensure that the force applied by the sliding frame 30 to the expansion card 50 is balanced when pulling out, the present embodiment is provided with a plurality of stop portions 31, and the stop portions 31 are arranged in parallel and at intervals along the side of the expansion card 50, so that the stop portions 31 can respectively abut against different positions of the same side of the expansion card 50, thereby applying force to the entire side of the expansion card 50, ensuring uniform force on the expansion card 50 and ensuring the pulling out effect.

[0049] like Figures 4 to 6 As shown, in the present embodiment, considering that the rotating frame 20 is arranged in a rotating manner, and the sliding frame 30 is arranged in a moving manner, when the rotating frame 20 drives the sliding frame 30 to move a certain distance, a jamming situation may occur between the two, so that the rotating frame 20 cannot continue to rotate, and the opening range of the rotating frame 20 is affected, so that the rotating frame 20 cannot rotate at an obtuse angle and cannot be fully opened, which affects the convenience of installing and removing the expansion card 50. Based on this, the server expansion card installation frame of the present embodiment further includes a locking mechanism 40, which is connected to the rotating frame 20. Accordingly, the sliding frame 30 has a locking end 32, and the locking mechanism 40 and the locking end 32 can be docked and can be The locking mechanism 40 and the locking end 32 are engaged with each other, so that the rotating frame 20 drives the sliding frame 30 to move through the cooperation between the locking mechanism 40 and the locking end 32, thereby realizing the extraction of the expansion card 50. When the sliding frame 30 does not need to continue to move after the expansion card 50 is extracted and the rotating frame 20 needs to continue to rotate to be fully opened, the locking mechanism 40 and the locking end 32 are separated, so that the rotating frame 20 idles relative to the sliding frame 30, and the rotation of the rotating frame 20 no longer drives the sliding frame 30 to move, so that the rotating frame 20 can be conveniently opened at a larger angle, thereby facilitating the extraction and insertion of the expansion card 50.

[0050] like Figure 6As shown, the locking mechanism 40 of this embodiment includes a bracket 41 and a reset member 42. The bracket 41 is movably connected to the rotating frame 20 along the length direction of the rotating frame 20. The bracket 41 has a locking hook portion 411, so that the bracket 41 can achieve docking and separation with the locking end 32 by moving or avoiding the locking end 32 during the rotation process. The locking hook portion 411 of this embodiment extends along the length direction of the rotating frame 20. A convex column is provided on the sliding frame 30 as the locking end 32. The convex column can be located in the locking hook area of ​​the locking hook portion 411, so that the convex column abuts against the side wall of the locking hook area. At this time, the locking mechanism 40 and the locking end 32 are in a docking and matching state. The locking hook portion 411 and the locking end 32 are limitedly matched, so that when the rotating frame 20 rotates, the locking hook portion 411 hooks the convex column to drive the sliding frame 30 to move. Since the convex column has a certain activity space in the locking hook area, the convex column will not be stuck when the rotating frame 20 rotates, so that the movement of the sliding frame 30 is smoother. The reset member 42 of this embodiment is a spring that abuts against the lock hook portion 411 , thereby providing a reset force for the lock hook portion 411 to move toward the locking end 32 , so that the lock hook portion 411 can automatically dock with the locking end 32 .

[0051] like Figure 7 and Figure 8 As shown, in this embodiment, a guide slope is provided on the side of the lock hook portion 411 facing the plug-in end 11, that is, the outer side of the lock hook portion 411 away from the lock hook area. The guide slope is an inclined surface. In this way, when the boss is located outside the lock hook area, if the boss needs to be located in the lock hook area to achieve docking, it is only necessary to rotate the rotating frame 20. The rotating frame 20 rotates relative to the sliding frame 30 and approaches the sliding frame 30. The lock hook portion 411 gradually approaches the boss until the boss abuts against the guide slope. Then, the rotating frame 20 continues to rotate, and the boss is squeezed and matched with the guide slope. Since the guide slope is inclined, the extrusion of the boss causes the bracket 41 to The lock hook portion 411 moves in a direction away from the protruding column relative to the movement of the rotating frame 20. As the rotating frame 20 continues to rotate, the lock hook portion 411 gradually moves away from the protruding column until the protruding column passes over the lock hook portion 411. At this time, the lock hook portion 411 moves in a direction close to the protruding column under the action of the reset member 42, so that the protruding column extends into the lock hook area. At this time, the lock hook portion 411 passes over the locking end 32 to achieve docking between the two. In this way, it is only necessary to rotate the rotating frame 20 to automatically switch the lock hook portion 411 and the locking end 32 to the docking state, thereby achieving automatic docking. This process does not require manual operation by personnel, thereby improving convenience of use.

[0052] like Fig.11 As shown, in this embodiment, the lock hook portion 411 of the locking mechanism 40 has a rotation trajectory when driven by the rotating frame 20, that is, Fig.11The locking end 32 has a sliding trajectory under the drive of the sliding frame 30, ie Fig.11 The longitudinal straight line passing through the locking end 32 is arranged to intersect with the rotating track line and the sliding track line. In this way, since the two track lines intersect, when the lock hook part 411 is driven by the rotating frame 20 to rotate in the direction away from the plug-in end 11, it can drive the sliding frame 30 to move through the locking end 32. When the rotating frame 20 drives the sliding frame 30 to move a predetermined distance in the direction away from the plug-in end 11, since the rotating frame 20 is in a rotating form and the side of the lock hook part 411 facing the locking end 32 is an open structure, the protrusion can be disengaged from the open side of the lock hook part 411, so that the lock hook part 411 is separated from the locking end 32. Then, when the rotating frame 20 continues to rotate, the rotating frame 20 idles relative to the sliding frame 30, and the rotating frame 20 can be rotated to be fully opened to facilitate the loading and removal of the expansion card 50. Fig. 9 shown.

[0053] Based on the above, when the rotating frame 20 rotates in the direction away from the plug-in end 11, the lock hook portion 411 and the locking end 32 will automatically separate. Therefore, when the rotating portion rotates in the direction close to the plug-in end 11, the lock hook portion 411 will also automatically dock with the locking end 32, and the locking end 32 does not necessarily need to contact the guide bevel. The reason why the guide slope is provided in the present embodiment is that when the expansion card 50 is loaded, the force with which the staff loads the expansion card 50 is uncertain. During the loading process, the expansion card 50 may abut against the stopper 31, causing the expansion card 50 to push the sliding frame 30 to move a certain distance into the tray 10. At this time, when the rotating frame 20 rotates in the direction close to the plug-in end 11, the position of the sliding frame 30 changes, so that the locking hook portion 411 and the locking end 32 can no longer dock in the reverse process of the withdrawal. At this time, the locking end 32 will abut against the guide slope, causing the locking hook portion 411 to move along the length direction of the rotating frame 20, thereby achieving the re-docking and cooperation between the locking hook portion 411 and the rotating frame 20. When the staff does not push the sliding seat to move when loading the expansion card 50, when the rotating frame 20 rotates in the direction close to the plug-in end 11, the locking end 32 will not abut against the guiding inclined surface, and the locking end 32 can directly pass over the locking hook portion 411 until the side of the rotating frame 20 abuts against the locking end 32, so that the locking end 32 extends into the locking hook area to achieve re-docking between the locking hook portion 411 and the locking end 32. Through the above-mentioned setting, when loading the expansion card 50, the staff does not need to consider the loading force, but only needs to load the expansion card 50 into the tray 10, and the subsequent rotating frame 20 and the sliding frame 30 can achieve automatic docking and matching through the setting of the locking mechanism 40 and the locking end 32.

[0054] In this embodiment, a plurality of slide grooves are provided on the bracket 41, and a cylinder is correspondingly provided on the rotating frame 20. The cylinder is located in the slide groove, so that the bracket 41 can slide along the length direction of the rotating frame 20 through the cooperation of the slide groove and the cylinder.

[0055] like Figure 2 As shown, in this embodiment, the tray 10 has a plurality of limiting portions 12, and the limiting portions 12 enclose an accommodation area for accommodating the expansion card 50, and the sliding frame 30 is located in the accommodation area. The setting of the limiting portions 12 can further limit the movement range of the expansion card 50, so that the expansion card 50 can only be inserted into the plug-in end 11 in a predetermined direction, avoiding the expansion card 50 from being offset, etc., and ensuring stable and reliable insertion.

[0056] like Fig.13 As shown, optionally, the limiting portion 12 of this embodiment includes a first limiting protrusion 121 and a second limiting protrusion 122. The first limiting protrusion 121 of this embodiment is located on the surface of the tray 10 and protrudes toward the direction of the sliding frame 30. The expansion card 50 is supported on the first limiting protrusion 121, so that the first limiting protrusion 121 is located below the expansion card 50, which plays the effect of supporting the expansion card 50 and limiting the expansion card 50 to move downward. At the same time, the first limiting protrusion 121 of this embodiment is provided in plurality, and the first limiting protrusion 121 is provided on both opposite sides of the sliding frame 30. The sliding frame 30 is located between the first limiting portion 12, and the height of the sliding frame 30 is lower than the first limiting protrusion 121, so that the first limiting protrusion 121 can play the role of supporting and limiting, and can also separate the expansion card 50 and the sliding frame 30, so as to prevent the expansion card 50 from being affected by other factors of the sliding frame 30. At the same time, since the first limiting protrusion 121 has a certain height, there is space between the sliding frame 30 and the tray 10 to set a sliding structure such as a guide rail, so that the sliding frame 30 can slide smoothly relative to the tray 10.

[0057] The second limiting protrusions 122 are located on two opposite sides of the accommodating area and can abut against the side of the expansion card 50. In this embodiment, there are also multiple second limiting protrusions 122, and second limiting protrusions 122 are respectively provided on the left and right opposite sides of the expansion card 50, wherein the second limiting protrusions 122 on one side can be realized by setting an IO retaining wall, and the second limiting protrusions 122 on the other side can be provided with a bending section that bends upward on the sliding seat, and the heights of the bending section and the IO retaining wall are both higher than the first limiting protrusion 121, so that the bending section and the IO retaining wall can play a limiting and stopping role on the left and right sides of the expansion card 50, and realize the functions of limiting, positioning, guiding, etc. of the expansion card 50 in multiple directions. Of course, the specific structural form of the limiting portion 12 can also be adjusted as needed, for example, a baffle and other structures can be set to achieve the limiting of the expansion card 50.

[0058] like Fig.13 As shown, in this embodiment, one of the sliding frame 30 and the tray 10 has an elastic protrusion 33, and the other of the sliding frame 30 and the tray 10 has a through hole. In this embodiment, the sliding frame 30 is provided with an elastic protrusion 33, and the elastic protrusion 33 has a long connecting arm, so that the elastic protrusion 33 can undergo a certain deformation, and the surface of the elastic protrusion 33 is hemispherical, and the tray 10 is provided with a through hole. When the expansion card 50 is not plugged in, the elastic protrusion 33 is misaligned with the through hole, and the elastic protrusion 33 abuts against the surface of the tray 10. When the expansion card 50 is plugged into the plug-in end 11, the elastic protrusion 33 is aligned with the through hole, and the elastic protrusion 33 extends into the through hole, thereby providing the staff with an operating feel, so that the staff can sense that the expansion card 50 is plugged in, and no further force is required. At the same time, when the expansion card 50 is loaded, the elastic protrusion 33 can also transmit a resistance to the staff, so that the staff can be intuitively reminded to load in place and rotate the rotating frame 20.

[0059] It should be noted that the cooperation between the elastic protrusion 33 and the through hole only provides an operational feel, and does not hinder the movement of the sliding frame 30 relative to the tray 10. When the rotating frame 20 drives the sliding frame 30 away from the plug-in end 11, the elastic protrusion 33 can easily withdraw from the through hole.

[0060] like Fig.15 As shown, in this embodiment, the operating end 23 of the rotating frame 20 has a spherical center protrusion 24, and the tray 10 has a through hole. When the rotating frame 20 pushes the expansion card 50 to be plugged into the plug-in end 11, the spherical center protrusion 24 is located in the through hole. When the spherical center protrusion 24 is inserted into the through hole of the tray 10, the center of the ball may be recessed inward into the entity, pass through the through hole of the tray 10, and then bounce out, thereby forming a structural form without screw fixation, and the structure is simpler.

[0061] It should be noted that, the multiple in the above embodiments refers to at least two.
