[0002] In data centers, high-performance computing, and cloud computing, server internal space is limited, but hardware requirements are constantly increasing. Traditional PC Ie slot layouts may not be able to accommodate all expansion card requirements, so expansion solutions such as Riser cards are needed to add additional slots.

[0003] As PCIe bus speeds increase, signal attenuation and integrity issues become increasingly prominent. Traditional PCB traces produce significant insertion loss during high-speed signal transmission, impacting signal quality. Therefore, new transmission media and connection methods are needed to address these issues. To address attenuation issues in high-speed signal transmission, such as PCIe 5.0, using high-speed cables as the transmission medium is an effective solution.

[0004] When multiple expansion cards are connected to a riser card, problems such as cable clutter and excessive dust may occur. Therefore, a riser card is provided that integrates a high-speed cable and a PCIe CEM connector. Utility Model Content

[0029] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0030] See also Figures 1-8As shown, the purpose of this embodiment is to provide a riser card that integrates a high-speed cable and a PCIe CEM connector, including a riser card body 2 and a fixed frame 1 for fixing the riser card body 2. The fixed frame 1 is rotatably provided with a flip cover 3 for dust prevention. The flip cover 3 and the fixed frame 1 together form a space for accommodating the riser card body 2, which can play a dust-proof role. The riser card body 2 includes at least a PCIe CEM connection slot 22 and a high-speed cable slot 23. The high-speed cable slot 23 is fixedly provided with a wiring harness on both sides to avoid confusion. The riser card body 2 is also clamped with a partition 4.

[0031] The fixing frame 1 is a U-shaped structure with one side longer than the other. The riser card body 2 is mounted on the longer side wall and arranged parallel to the side wall. The fixing frame 1 is used to mount the riser card body 2. The upper and lower ends of the side walls are fixedly provided with fixing bars 11. The sides of the two fixing bars 11 that are close to each other are respectively provided with square grooves 111 along their own length directions. The ends of the square grooves 111 are open to facilitate the insertion of the riser card body 2.

[0032] Furthermore, in order to ensure that riser card body 2 is stably inserted into square slot 111 , elastic rubber strips may be provided at the upper and lower ends of riser card body 2 .

[0033] A groove 13 is formed on the top of the fixed frame 1 , and a rotating shaft is rotatably provided in the groove 13 . The rotating shaft is fixedly mounted on one end of the flip cover 3 , and the flip cover 3 rotates in the groove 13 along the axis of the rotating shaft.

[0034] Limiting grooves 12 are provided on both sides of the fixing frame 1 , and blocks are fixedly provided on both sides of the flip cover 3 , and the blocks are snap-fitted into the limiting grooves 12 .

[0035] When riser card body 2 needs to be plugged into fixed frame 1, flip cover 3 is opened so that the user can see the position of square slot 111 more clearly, thereby ensuring the accuracy of the plugging process. After the plugging is completed, the square block of flip cover 3 is snap-fitted into limit slot 12, thereby fixing flip cover 3 to fixed frame 1, preventing dust, debris or other potential damaging factors from contacting the slot and riser card body 2, helping to keep the slot clean and intact, and ensuring that riser card body 2 can work stably and reliably.

[0036] The riser card body 2 is fixedly provided with a plurality of expansion slots 21, and expansion cards are inserted into the expansion slots 21. When an expansion card is inserted into the end of the expansion slot 21, the socket of the expansion slot 21 is blocked by a bolt provided on one side of the expansion slot 21, thereby fixing the position of the expansion card.

[0037] Two recessed blocks 24 are provided between adjacent expansion slots 21. Recessed blocks 24 are also symmetrically provided on the side walls of the fixed frame 1 opposite to the riser card body 2. Recessed blocks 24 are mounting blocks protruding from the surface of the riser card body 2. The surface away from the riser card body 2 is recessed to form a sliding groove with an open end. The same partition 4 is slidably engaged with the recessed blocks 24 at corresponding positions on the two side walls of the fixed frame 1. The partition 4 can separate adjacent expansion slots 21, providing independent space for each expansion slot 21 and the expansion card installed therein, which helps to avoid physical interference between different hardware and ensure that each hardware can work properly.

[0038] There are two through slots 31 in the flip cover 3. When the partition 4 does not need to be snapped onto the recessed block 24, the partition 4 is inserted into the through slots 31. The through slots 31 in the flip cover 3 provide a convenient storage location for the partition 4. When the user needs to replace or adjust the partition, it can be easily taken out from the through slots without having to search for it inside the server, which saves storage space. A number of heat dissipation holes are provided through the flip cover 3 and the partition 4. When the partition 4 is inserted into the through slots 31 for storage, the heat dissipation holes of the flip cover 3 and the partition 4 are aligned up and down. The design of the heat dissipation holes can effectively circulate air to prevent internal overheating and damage to components.

[0039] The cable harness portion includes a connecting block 231 fixedly set on the riser card body 2, and the connecting block 231 is located on both sides of the high-speed cable slot 23. A connecting rod 232 is fixedly set on the connecting block 231, and an arc block 233 is fixedly set at one end of the connecting rod 232. The arc block 233 is semi-circular in shape. Cables are placed between the arc blocks 233 so that the cables can be neatly arranged along their arc surfaces, which helps to reduce entanglement and confusion between cables and makes cable management easier. Fixed blocks 234 are fixedly set at both ends of the arc block 233, and the fixed blocks 234 are fixedly connected by screws.

[0040] Space inside a server chassis is often very limited. By making the side where the mounting frame 1 and riser card 2 meet longer than the opposite side, the vertical and horizontal space within the chassis can be more effectively utilized, allowing more hardware devices to be installed within the limited space. This also helps simplify the wiring within the server. By properly planning the wiring paths, cable crossover and interference can be reduced, improving the neatness and maintainability of the wiring.

[0041] When the present invention is used, the high-speed cable is plugged and fixed in the high-speed cable slot 23, the PCIe CEM is plugged and fixed in the PCIe CEM connection slot 22, and the expansion card is plugged and fixed in the expansion slot 21. Then, the fixing block 234 is fixedly connected by screws, thereby fixing the cables between the arc blocks 233 to prevent entanglement. The flip cover 3 is opened, the riser card body 2 is plugged and set in the square groove 111, the partition 4 is taken out from the through groove 31, and then the partition is snap-fitted and set on the concave block 24. Then, the flip cover 3 is closed, and the square block is snap-fitted and set in the limit groove 12, thereby fixing the flip cover 3 on the fixed frame 1, and finally, the fixed frame 1 is fixedly mounted on the chassis.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
