Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of display card assembly, and particularly to a display card PCIE quick release structure. BACKGROUND

[0002] PCIe (Peripheral Component Interconnect Express) is a high-speed serial expansion bus standard, introduced by PCI-SIG (PCI Special Interest Group) in 2003, aiming to replace the traditional PCI and AGP bus, and become the main connection interface between modern computer hardware. PCIe adopts a point-to-point full-duplex communication architecture, providing extremely high bandwidth through flexible lane design, and its speed gradually increases with the evolution of the standard, such as PCIe 3.0, 4.0, and 5.0, which support transmission rates of 8, 16, and 32 GT / s per lane, respectively, and are widely used in devices such as graphics cards, NVMe solid-state disks, network cards, etc. In terms of physical structure, PCIe slots are located on the motherboard and come in different sizes (such as x1, x4, x8, x16), with varying lengths and bandwidths to match different device requirements; its design includes a gold finger interface, a fixed buckle, and a baffle screw hole, etc., to ensure the stability of the device in the slot and the reliability of signal transmission. When installing, align the gold finger and insert it evenly into the slot, fix the baffle screw, and it is complete. When disassembling, you need to loosen the screw first, then release the device by prying the buckle at the tail of the slot, and finally gently pull out the device. Due to its high performance and compatibility, PCIe has become the core technology for connecting computer hardware, widely used in high-performance computing, storage, and network fields.
