The high-speed connector a12 is a SlimSAS or MCIO output interface. The cable 3 slides in the shrinking slots 322 and the connecting slots 324 to control the length of the cable 3 outside the shrinking slot 322. Each CPU 11 leads out 48 sets of PCIe 4.0 high-speed links. Every 8 sets of PCIe high-speed links use one SlimSAS or MCIO high-speed connector a12 as the output port on the motherboard side.

[0028] A high-speed connector b21 is fixedly mounted on the side wall of the RISER card 2. Several slots 22 are formed on the upper surface of the RISER card 2. These slots 22 are used to create various high-speed resource topologies. The RISER card 2 can be designed in various forms such as PCIe CEM SLOT single-slot, dual-slot, and triple-slot configurations. The motherboard 1 is connected to various RISER cards 2 using high-speed flexible cables 3. This eliminates the limitations of the RISER card 2's fixed position, quantity, and type caused by the rigid interconnection between the gold fingers and the motherboard. Within the same 2U server chassis, various high-speed resource topologies can be created. A total of four single-slot RISER cards 2 are connected to eight SlimSAS high-speed connectors a12 on the motherboard 1 via flexible cables 3, enabling the server to accommodate four full-speed RISER cards. Two full-length, double-width GPU cards and one dual-slot RISE card are connected to the 12 SlimSAS high-speed connectors a12 on the motherboard 1 via flexible cables 3, enabling the server to accommodate 6 full-length, single-width GPU cards and 2 PCIe standard cards. Alternatively, two triple-slot RISE cards and two dual-slot RISE cards are connected to the 12 SlimSAS high-speed connectors a12 on the motherboard 1 via flexible cables 3, enabling the server to accommodate 8 half-length, single-width GPU cards and 2 PCIe standard cards.

Cable 3 interconnects motherboard 1 and RISER card 2, allowing RISER card 2 to be flexibly arranged in the chassis.

[0030] At least one limiting shaft a34 is slidably installed within the shrinkage groove 322. A connecting block 341 is fixedly installed at one end of the limiting shaft a34. A threaded hole 342 is formed through the connecting block 341 on the side near the edge of the shrinkage block 32. A bolt is threaded into the threaded hole 342. A clamping block a344 ​​is fixedly installed on the side wall of the limiting shaft a34 near one end edge. A clamping block b345 is fixedly installed on the side wall of the clamping block a344 ​​near the upper edge. The clamping block b345 has an arc-shaped structure and is located directly above the limiting shaft a34. This design can better... Secure the cable 3 to the limiting shaft a34; a cable release groove is reserved between the clamping block b345 and the limiting shaft a34, the cable 3 passes through the cable release groove and the cable release groove provides a limit for the cable 3, the limiting shaft b36 is slidably installed in the connecting groove 324, the limiting shaft b36 has the same structure as the limiting shaft a34, the limiting shaft a34 and the limiting shaft b36 are slid to push the cable 3 to slide, so as to adjust the length of the cable 3. When the cable 3 is adjusted to the specified length, the bolt in the threaded hole 342 is tightened to press against the side wall of the shrink block 32 to fix the position of the limiting shaft a34, thereby fixing the cable 3.

[0031] A cable feeding groove is reserved between the clamping block b345 and the limiting shaft a34. The cable 3 passes through the cable feeding groove and is limited by the cable feeding groove. The limiting shaft b36 is slidably installed in the connecting groove 324. The limiting shaft b36 has the same structure as the limiting shaft a34.

[0032] A mounting plate 33 is fixedly installed on one side of the shrink block 32. Several sliding grooves 331 are opened through the side wall of the mounting plate 33, and the sliding grooves 331 are vertically aligned with the shrink groove 322. A limiting block a343 is fixedly installed on one side of the limiting shaft a34. The limiting block a343 is slidably engaged in the sliding groove 331. A limiting groove 323 communicating with the sliding groove 331 is opened near one edge of the connecting groove 324.

The limiting shaft a34 slides along the sliding groove 331 through the limiting block a343, and the limiting shaft b36 slides along the limiting groove 323 through the limiting block b361. When the length of the cable 3 needs to be increased, the spring 351 pulls the limiting shaft b36 to slide upward. Here, the spring 351 can effectively control the movement path of the limiting shaft b36 and help it to quickly reset. When the specified length is reached, the bolt in the threaded hole 342 is tightened to press against the side wall of the shrink block 32 to fix the position of the limiting shaft b36.

[0035] In practical use, the connector 31 on one side of the cable 3 is fixedly installed on the high-speed connector b21 on the RISER card 2, and the connector 31 on the other side of the cable 3 is fixedly installed in the high-speed connector a12 on the motherboard 1. When it is necessary to adjust the length of the cable 3 in the shrinkage groove 322, the sliding limit shaft a34 and the limit shaft b36 push the cable 3 to slide, so as to adjust the length of the cable 3 outside the shrinkage groove 322. When the cable 3 is adjusted to the specified position, the bolt in the threaded hole 342 is tightened to press against the side wall of the shrinkage block 32 to fix the position of the limit shaft a34. When it is necessary to increase the length of the cable 3, the spring 351 pulls the limit shaft b36 to slide upward to increase the length of the cable 3.
