[0036] It should be further understood that the term "and / or" as used in the present application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0037] This invention provides a PCIe card mounting device for use in a 1U chassis, enabling the chassis to accommodate as many PCIe cards as possible while allowing for quick removal and removal. Specific embodiments of the invention are described below.

[0038] like Figures 1-6 As shown, the PCIe card fixing device includes a riser module bracket 1, a sliding limiting structure 2, and a PCIe card connector 5 for fixing the PCIe card 100. The riser module bracket 1 includes a card support base plate 11, a first side limiting plate 12 and a second side limiting plate 13 disposed on adjacent sides of the card support base plate 11, and a third side limiting plate 15 disposed on the side opposite to the first side limiting plate 12. A locking structure 3 is provided at one end of the second side limiting plate 13 near the third side limiting plate 15. The locking structure 3 includes a locking groove 31, and a locking slot 311 is provided on the side wall of the locking groove 31; the sliding limiting structure 2 is provided with an elastic element 23 and a locking arm 221 that engages with the locking slot 311; in the unlocked state, the locking arm 221 engages with the locking slot 311, and the elastic element 23 is compressed; in the locked state, the locking arm 221 is released from engagement with the locking slot 311, and under the elastic force of the elastic element 23, the sliding limiting structure 2 limits and fixes the area where the PCIE card connector 5 is embedded in the locking groove 31.

[0039] The PCIe card 100 is generally rectangular in shape. The PCIe card connector 5 is located on one side of the width direction of the PCIe card 100. The PCIe card 100 and the PCIe card connector 5 are connected by screws or other means. After the PCIe card 100 and the PCIe card connector 5 are connected, they are installed as a whole on the Riser module bracket 11.

[0040] A Cable Riser card connector 4 for inserting a PCIe card 100 is fixedly connected to the inner side of the first side limiting plate 12. For example... Figure 6 As shown, from Figure 6It can be seen that when the PCIE card 100 and the PCIE card connecting piece 5 are installed as a whole on the Riser module support 1, the first side limiting plate 12 is located on one side of the PCIE card 100 in the length direction and limits the side. The second side limiting plate 13 is located on one side of the PCIE card 100 in the width direction and limits the side. The third side limiting plate 15 is located on the other side of the PCIE card 100 in the length direction, and the sliding limiting structure 2 is located between the third side limiting plate 15 and the other side of the PCIE card 100 in the length direction. In the locked state, the sliding limiting structure 2 is limited and fixed to the area where the PCIE card connecting piece 5 is embedded in the card slot 31 under the action of the elastic force, and the other side of the PCIE card 100 in the length direction is limited. If you want to unlock, apply a force to the sliding limiting structure 2 in the opposite direction of the elastic force, so that the clamping arm 221 is clamped with the card mouth 311, thereby giving the PCIE card 100 and the PCIE card connecting piece 5 space to be removed from the Riser module support 1.

[0041] The PCIE card 100 is fixed by the designed sliding limiting structure 2. By sliding the sliding limiting structure 2 to different positions, the PCIE card 100 can be locked or unlocked without using screws or other connecting pieces for fixation. The sliding limiting structure 2 does not occupy the space in the height direction of the 1U case 200, and can ensure that two PCIE cards 100 are installed in the height direction while achieving the effect of quick disassembly. In addition, the elastic element 23 is provided to elastically limit and fix the PCIE card 100 in the locked state. Only under the action of external force can the limiting state be released, and the structure is stable.

[0042] In some embodiments, as shown in Figure 3 、 4 , the adjacent positions of the first side limiting plate 12 and the second side limiting plate 13 are provided with an insertion opening 14, and at least part of the PCIE card connecting piece 5 is embedded in the insertion opening 14. The insertion opening 14 can limit the PCIE card connecting piece 5.

[0043] In an embodiment, as shown in Figure 4 、 5 , the PCIE card connecting piece 5 includes a vertical plate part 51 parallel to the width direction of the PCIE card 100, and a folding edge part 53 and an embedded part 52 provided at both ends of the vertical plate part 51. The folding edge part 53 constitutes the area where the PCIE card connecting piece 5 is embedded in the card slot 31, and the embedded part 52 constitutes the area where the PCIE card connecting piece 5 is embedded in the insertion opening 14. The length direction of the folding edge part 53 is perpendicular to the length direction of the vertical plate part 51, and the length direction of the embedded part 52 is parallel to the length direction of the vertical plate part 51.

[0044] When the PCIE card connector 5 is installed in the Riser module support 1, the upright plate part 51 of the PCIE card connector 5 is just close to the second side limiting plate 13, the embedded part 52 is placed in the insertion opening 14, and the folded edge part 53 is placed in the card slot 31.

[0045] Preferably, in order to facilitate manufacturing, the PCIE card connector 5 is made by one-piece forming process.

[0046] In an embodiment, as shown in Figure 2 , 3 , the sliding limiting structure 2 includes a card part 22 and a limiting part 21, the card part 22 is located in the card slot 31, the limiting part 21 is located outside the card slot 31, the card part 22 is provided with a clamping arm 221, and the limiting part 21 is provided with an elastic member 23.

[0047] In the embodiment, the card part 22 and the limiting part 21 are one-piece structure, of course, in other embodiments, they are separate structure. The elastic member 23 is a spring.

[0048] In an embodiment, as shown in Figure 2 , one end of the clamping arm 221 is fixedly connected to the card part 22, the other end is in a suspended state, and the end of the other end is provided with a hook-shaped part 2211 for hooking the card opening 311.

[0049] The clamping arm 221 is made of elastic material, such as plastic material. When the hook-shaped part 2211 of the clamping arm 221 is clamped into the card opening 311, the hook-shaped part 2211 abuts against the upper edge of the card opening 311, and when the clamping relationship between the two is to be released, the hook-shaped part 2211 can be pressed downward by force. Because the clamping arm 221 has a certain elasticity, the clamping fit is more firm.

[0050] In an embodiment, as shown in Figure 5 , the limiting part 21 is provided with a positioning groove 211, the side surface of the positioning groove 211 is provided with a positioning protrusion 2111, one end of the elastic member 23 is sleeved on the positioning protrusion 2111, and the other end abuts against the third side limiting plate 15.

[0051] Part of the elastic member 23 is located in the positioning groove 211, and part of the elastic member 23 is stretched out of the positioning groove 211 and abuts against the third side limiting plate 15. When the hook-shaped part 2211 of the clamping arm 221 is clamped with the card opening 311, the elastic member 23 is in a compressed state at this time. When the hook-shaped part 2211 of the clamping arm 221 is not clamped with the card opening 311, the elastic member 23 returns to the initial stretched state under the action of the restoring force. In the stretched state, it is a limiting and fixed state of the PCIE card connector 5 and the PCIE card 100, so that the stability and reliability of the limiting and fixing are improved.

[0052] In some embodiments, the limiting part 21 is further provided with a guide hole arranged along the moving direction of the sliding limiting structure 2, and the guide hole is provided with a guide connecting piece fixedly connected with the clamping support bottom plate 11.

[0053] Through the cooperation of the guide connecting piece and the guide hole, the sliding limiting structure 2 is guided in movement, and the deviation of the moving direction of the sliding limiting structure 2 is avoided.

[0054] In the embodiment, the guide hole is in the shape of an oblong. The guide connecting piece is composed of a screw rod and a screw cap, and of course other forms of guide connecting pieces can also be adopted.

[0055] In the embodiment, since the third side limiting plate 15 is low in height, in order to prevent the sliding limiting structure 2 from being separated from the clamping support bottom plate 11 at the third side limiting plate 15, a partition plate designed in the case 200 is further used for blocking. Of course, in other embodiments, the height of the third side limiting plate 15 can be appropriately increased to avoid the sliding limiting structure 2 from being separated.

[0056] As shown in Figure 7 、 8 , Figure 7 、 8 , a state schematic view of the PCIE card fixing device in which the PCIE card 100 is installed is shown, Figure 7 and Figure 8 three installation positions are designed side by side, each installation position can stack two PCIE cards 100, and the three installation positions can stack six PCIE cards 100 in total, which meets the requirement of stacking more PCIE cards 100. In the prior art, due to the design of the fixing device, only one PCIE card 100 can be stacked in one installation position.

[0057] The embodiment of the application further provides a PCIE card 100 installation method, which comprises the following steps:

[0058] S10, fixing the PCIE card 100 on the PCIE card connecting piece 5;

[0059] S20, adjusting the sliding limiting structure 2 to an unlocked state;

[0060] S30, installing the PCIE card connecting piece 5 on which the PCIE card 100 is fixed on the Riser module support 1, connecting the PCIE card 100 to the Cable Riser card connector 4, and placing the folded edge part 53 of the PCIE card connecting piece 5 in the card slot 31;

[0061] S40, adjusting the sliding limiting structure 2 to a locked state to limit and fix the PCIE card connecting piece 5.

[0062] Specifically, after the PCIE card 100 is fixed on the PCIE card connector 5 by screws or other connectors, an installation whole is formed, then the sliding limiting structure 2 is adjusted to the unlocked state, i.e. the clamping of the clamping arm 221 and the clamping hole 311, and then the installation whole is placed on the clamping support bottom plate 11 of the Riser module support 1, when the folded edge part 53 and the embedded part 52 of the PCIE card connector 5 are placed in position, the PCIE card 100 is connected to the Cable Riser card connector 4, and then the sliding limiting structure 2 is adjusted to the locked state, i.e. the clamping of the clamping arm 221 and the clamping hole 311 is not formed, in this state, the sliding limiting structure 2 limits and fixes the PCIE card 100 and the folded edge part 53 of the PCIE card 100 under the elastic force of the elastic member 23.

[0063] As shown in Figure 7 , 8 When the PCIE card 100 and the PCIE card connector 5 are installed and fixed as a whole, the entire installed PCIE card fixing device is inserted into the corresponding installation position of the case 200, and is fixed by screws.

[0064] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
