Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to an installation device for an adapter card and a server. Background Art

[0002] The server's adapter card plays an important role in transferring multiple external cards (such as network cards, RAID cards, GPUs and other key components). The entire link of "external card - adapter card - adapter card" uses gold fingers as the transfer carrier for connecting power, signals and data. Taking PCIE4.0 as an example, the width of the gold finger is 0.7mm, and the distance between two adjacent gold fingers is only 1mm. At the same time, there may be a large tolerance between the length of the slot on the adapter card and the length of the gold finger. The precise alignment of the gold fingers on the board and the PCIE slot can effectively ensure the transmission of power, signals and data. If the gold fingers and the slots are misaligned, resulting in a short circuit between adjacent gold fingers, the system may not be able to recognize the board, or there may be problems with speed reduction and bandwidth reduction. In severe cases, the power supply may be short-circuited, the board may be burned, and even serious burn-in accidents may occur. In addition, as contact metal parts, gold fingers usually encounter surface oxidation, resulting in poor contact.

[0003] In the prior art, most adapter cards are usually manually inserted and removed by fitting the gold fingers on the board into the corresponding slots. Secondary insertion and removal also requires manual direct insertion and removal. Due to different pressing forces during manual operation, the installation depths of the gold fingers at different positions are inconsistent, which causes the insertion misalignment between the gold fingers and the slots. In addition, during the secondary insertion and removal process, the manual operation requires manually pulling out the adapter card upwards and then pressing it downwards to achieve secondary insertion and removal of the adapter card. The operation is extremely inconvenient, and the operating efficiency and quality cannot be guaranteed. Summary of the invention

The disk structure 42 has an arc-shaped guide groove 421. In the direction from the slot opening to the slot bottom of the arc-shaped guide groove 421, the center distance between the arc-shaped guide groove 421 and the pivot shaft 43 is gradually reduced; when the lever assembly 40 rotates in a preset direction to allow the positioning column 121 to slide from the slot opening to the slot bottom, the carrier bracket 20 slides toward one side of the mainboard 1 so that the plug-in structure 31 of the adapter card 30 is plugged and matched with the plug-in slot structure 101 on the mainboard 1; when the lever assembly 40 rotates in a direction opposite to the preset direction to allow the positioning column 121 to withdraw from the slot bottom to the slot opening, the carrier bracket 20 slides away from the side of the mainboard 1 so that the plug-in structure 31 of the adapter card 30 withdraws from the plug-in slot structure 101.

[0040] By applying the technical solution of the present invention, there is provided an installation device for an adapter card, comprising a positioning bracket 10, a carrier bracket 20 and a lever assembly 40, wherein the positioning bracket 10 is used to be connected to the mainboard 1 of the server, and a positioning column 121 is protrudingly provided on the side surface of the positioning bracket 10; the carrier bracket 20 is slidably connected to the positioning bracket 10, and the carrier bracket 20 has an avoidance slide groove 2321 for avoiding the positioning column 121, and the carrier bracket 20 also has a accommodating area 211 and a accommodating space 100 connected to the accommodating area 211, wherein the accommodating area 211 is used to accommodate the adapter card 30, and the accommodating space 100 is connected to the avoidance slide groove 2321, so that the positioning column 121 passes through the avoidance slide groove 2321 and extends into the accommodating space 100; the lever assembly 40 comprises a rod body 41 and a The disk structure 42; the disk structure 42 is located in the accommodating space 100 and is pivotally connected to the carrier bracket 20 through a pivot shaft 43.

In the direction from the notch of the arc-shaped guide groove 421 to the bottom of the groove, the center distance between the arc-shaped guide groove 421 and the pivot shaft 43 is gradually reduced; when the lever assembly 40 rotates in a preset direction to allow the positioning column 121 to slide from the notch to the bottom of the groove, the carrier bracket 20 slides toward one side of the mainboard 1 so that the plug-in structure 31 of the adapter card 30 is plugged and matched with the plug-in slot structure 101 on the mainboard 1; when the lever assembly 40 rotates in a direction opposite to the preset direction to allow the positioning column 121 to withdraw from the bottom of the groove to the notch, the carrier bracket 20 slides away from the side of the mainboard 1 so that the plug-in structure 31 of the adapter card 30 withdraws from the plug-in slot structure 101.

[0041] By rotating the lever assembly 40 along a preset direction, the positioning column 121 on the positioning column 121 moves from the slot to the direction of sliding into the bottom of the slot.
