Description

A non-standard daughter card fixing device

technical field

The utility model relates to the field of computer systems, in particular to a fixing device for a non-standard daughter card.

Background technique

In a 1U chassis, non-standard sub-cards cannot share a standard back plate, so when fixing such sub-cards, it is often chosen to open screw holes on the motherboard for fixing. Different subcards have different requirements for screw holes, and this method of opening screw holes on the motherboard lacks versatility. And opening screw holes on the main board will occupy the PCB space of the main board. Therefore, the technology of installing non-standard daughter cards in a 1U chassis needs to be further developed or improved.

Utility model content

The utility model aims at the problems existing in the prior art, and provides a non-standard daughter card fixing device with a simple structure.

The non-standard sub-card fixing device disclosed by the utility model is suitable for the fixed installation of non-standard sub-cards in a 1U chassis, and the technical solution adopted to solve the technical problem is as follows: including fixing shrapnel, PCIE card slot, screw, sub-card And its heat sink, wherein the upper end of the fixed spring has a screw hole and the lower end is provided with a hook, the side of the PCIE card slot is formed with a buckle, the heat sink is set on the sub-card, and the upper end of the fixed spring is fixed on the heat sink by screws. Realize the fixing of the fixed shrapnel on the sub-card, and at the same time, the hook at the lower end of the fixed shrapnel catches the buckle at the side of the PCIE card slot, and fixes the lower end of the fixed shrapnel on the PCIE card slot, so that the sub-card can be firmly installed on the motherboard.

The non-standard sub-card fixing device disclosed by the utility model has the beneficial effect that: use the device to fix non-standard sub-cards in a 1U chassis, avoid opening holes on the main board, reduce the impact on the main board, and save the main board PCB at the same time Space, and simple structure, easy disassembly and assembly, with strong versatility and practicability.

Detailed ways

The fixing device for the non-standard daughter card disclosed in the present utility model will be described in further detail below in conjunction with the accompanying drawings.

The subcard fixing device described in the utility model is proposed in view of defects such as the need for screw holes on the main board in the installation of non-standard subcards in a 1U chassis, and the method has poor versatility and occupies the PCB space of the main board. The use state of the fixing device is shown in Figure 1, including a fixing elastic piece 1, a PCIE card slot 2, a screw 3, a sub-card 4 and its heat sink 5, wherein the upper end of the fixing elastic piece is provided with a screw hole and the lower end is provided with a hook 6, and the PCIE Buckle 7 is formed on the side of the card slot, heat sink 5 is set on daughter card 4, and the upper end of the fixed spring is fixed on heat sink 5 by screw 3, that is, fixed spring 1 is fixed to daughter card 4 through heat sink 5, At the same time, the hook 6 at the lower end of the fixed shrapnel blocks the buckle 7 at the side of the PCIE card slot, and the lower end of the fixed shrapnel is fixed on the PCIE card slot, so that the sub-card 4 can be firmly installed on the motherboard 8 .

To use the daughter card fixing device, firstly insert the daughter card with heat sink into the PCIE card slot, then match the screw holes on the upper end of the fixing shrapnel with the mounting holes on the heat sink, and use screws to fasten the fixing shrapnel on the On the heat sink, the fixed shrapnel can be fixed on the daughter card, and at the same time, the hook at the lower end of the fixed shrapnel catches the buckle on the side of the PCIE card slot to play a fixing role. The fixing device is easy to disassemble and assemble when in use, no need to disassemble and assemble screws, just use the lower end of the fixing shrapnel to move the hook out of the side buckle of the PCIE card slot to remove the sub-card. Using the fixing device to install the sub-card has strong versatility, so that the sub-card can be adapted to various main boards; holes are avoided on the main board, the impact on the main board is reduced, and the PCB space of the main board is also saved.

Except technical characterictic described in the utility model, be the known technology of those skilled in the art.
