Technical Field
[0001] This utility model relates to the field of connection structures, and more particularly to a server expansion card connection structure. Background Technology
[0002] In the server industry, riser cards typically connect to the server motherboard's motherboard slots via their gold fingers. Since these slots are in fixed positions, the PCIe resources allocated by the CPU to them are also fixed, resulting in limited flexibility in PCIe configuration.
[0003] Traditional servers connect riser cards by simply inserting the gold fingers of the card into the motherboard's gold finger slot. This is limited by the server's physical structure and restricts its scalability for various applications. Therefore, this paper proposes a server expansion card connection structure. Utility Model Content

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0023] Please see Figures 1-4 As shown, the purpose of this embodiment is to provide a server expansion card connection structure, including a sleeve 1, a rotating groove 11 on the side wall of the sleeve 1, a rotating shaft a12 rotatably mounted in the rotating groove 11, a mounting groove a13 penetrating the side wall of the rotating shaft a12, a high-speed cable 2 fixedly mounted in the mounting groove a13, a gold finger connector 21 fixedly mounted on one side of the high-speed cable 2, a high-speed connector a211 fixedly mounted on the other side of the high-speed cable 2, and a high-speed connector b23 fixedly mounted at one end of the high-speed cable 2. A mounting plate a3 is fixedly mounted on one side of the high-speed connector b23, a mounting groove b31 is opened on the side wall of the mounting plate a3, and several clamping mechanisms are fixedly mounted on the side wall of the mounting groove b31. By rotating the rotating shaft a12, the gold finger connector 21 and the high-speed connector a211 are switched according to the motherboard connector, and the clamping mechanisms improve the stability of the expansion card connection.
[0024] A number of branch lines 22 are fixedly installed at one end of the high-speed cable 2, and a high-speed connector b23 is fixedly installed at one end of the branch line 22. The high-speed connector b23 on different branch lines 22 is used to connect different expansion cards.
[0025] The sleeve 1 has a threaded hole 111 through which a connecting rotating groove 11 is opened. A bolt is installed in the threaded hole 111. Tightening the bolt in the threaded hole 111 tightens the side wall of the rotating shaft a12 to fix the position of the rotating shaft a12.
[0026] Rotating shaft a12 has rotating shaft b121 fixedly installed at both ends. One end of rotating shaft b121 passes through sleeve 1 and is exposed to the outside. Rotating sleeve 1 exposed to the outside is used to switch the interface.
[0027] A through hole with a connecting mounting groove b31 is provided at the center of the side wall of the mounting plate a3, and the high-speed connector b23 is fixedly installed in the through hole.
[0028] The clamping mechanism includes a spring 32. One end of the spring 32 is fixedly installed on the side wall of the mounting slot b31, and the other end of the spring 32 is fixedly installed on the mounting plate b33. Pushing the mounting plate b33 compresses the spring 32, and the spring 32 has elastic force. When the expansion card is placed into the mounting slot b31, the spring 32 pushes the mounting plate b33 to clamp the expansion card under the action of elastic force, preventing the expansion card from being installed unstablely.
[0029] In practical use, when multiple expansion cards need to be connected, the rotating shaft a12 is rotated to adjust the interface according to the motherboard interface. The bolt in the threaded hole 111 is tightened to press against the side wall of the rotating shaft a12 to fix the interface position. Several branch lines 22 are fixedly installed at one end of the high-speed cable 2, and a high-speed connector b23 is fixedly installed at one end of the branch line 22 for connecting different expansion cards. The mounting plate b33 is pushed to compress the spring 32. The spring 32 has elasticity. After the expansion card is placed in the mounting slot b31, the spring 32 pushes the mounting plate b33 to clamp the expansion card to fix the position of the expansion card and prevent the expansion card from being installed unstablely.
