[0002] In the prior art, expansion cards are available in different lengths, such as 60mm, 80mm, 110mm, etc., and the same motherboard is usually fixed with a front-locking hexagonal nut to install expansion cards of different lengths. However, when an ultra-low connector is used, the expansion card is very close to the motherboard, so that the gap between the expansion card and the motherboard is too small to lock the nut, and the expansion card cannot be fixed. If it is fixed, the end of the expansion card away from the connector will be lifted. Summary of the invention

[0003] According to an embodiment of the utility model, an expansion card fixing mechanism is provided for fixing an expansion card on a mainboard, one end of the expansion card is connected to a connector, and includes:

[0006] A spacer, the spacer is placed in the communicating hole and abuts against the nut, the spacer is provided with a connecting hole, the connecting hole runs through both ends of the spacer, and the connecting hole is connected with the inner hole of the nut;

[0007] The screw is screwed into the spacer and the nut, the head of the screw abuts against the expansion card, and the screw fixes the expansion card.

[0008] Furthermore, the raising member is a hollow sleeve or a hollow stud.

[0009] Further, nuts are welded to the bottom surface of the main board.

[0010] The expansion card fixing mechanism according to the embodiment of the utility model can be applicable to expansion cards of different lengths and connectors of different connection heights, has wide applicability and simple structure.

[0011] It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the technology as claimed. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0016] First, combine Figures 1 to 3 The expansion card fixing mechanism according to the embodiment of the utility model is described, which is used to fix the expansion card on the mainboard and has a wide range of application scenarios.

[0017] like Figures 1 to 3 As shown, the expansion card fixing mechanism of the embodiment of the utility model, one end of the expansion card 1 is connected to the connector 2, and includes: a connecting hole 3, a nut 4, a spacer 5 and a screw 6.

[0018] Specifically, Figures 1 to 3 As shown, in this embodiment, the connecting hole 3 passes through the mainboard 7 and is opposite to the other end of the expansion card 1, that is, the position of the connecting hole 3 is set according to the length of the expansion card 1 to adapt to expansion cards 1 of different lengths; the nut 4 is fixed to the bottom surface of the mainboard 7, increasing the distance between the nut 4 and the expansion card 1, and better adapting to connectors 2 of different heights, the inner hole of the nut 4 is connected with the connecting hole 3; the padding member 5 is placed in the connecting hole 3 and abuts against the nut 4, the padding member 5 is provided with a connecting hole, the connecting hole passes through both ends of the padding member 5, the connecting hole is connected with the inner hole of the nut 4, the padding member 5 supports and pads the expansion card 1, and the padding member 5 is a hollow sleeve or a hollow stud; padding members 5 of different heights can be used according to the height of the connector 2, so that the heights of both ends of the expansion card 1 are consistent; the screw 6 is screwed into the padding member 5 and the nut 4, the head of the screw 6 abuts against the expansion card 1, the screw 6 fixes the expansion card 1, and the expansion card 1 can be easily installed or replaced by tightening or loosening the screw 6, thereby improving the user's convenience. By using the combination of the nut 4, the spacer 5 and the screw 6, it is possible to ensure that the connection between the expansion card 1 and the mainboard 7 is very firm, reduce the risk of loosening or disconnection, and improve the stability and reliability of the mechanism.

[0019] Furthermore, in this embodiment, the nut 4 is welded to the bottom surface of the main board 7, and the structure is more compact and stable.

[0020] Working principle: weld the nut 4 on the back of the motherboard 7, and see from the front that at least half of the space in the connecting hole 3 is not filled, then place the hollow sleeve in the connecting hole 3 to achieve positioning, then install the expansion card 1, and tighten the screw 6. This solves the problem that when the ultra-low connector 2 is selected, the expansion card 1 is very close to the motherboard 7, and the gap there is too small to be fixed by the conventional fixing method. One end of the expansion card 1 is connected to the connector 2, and the other end is fixed between the screw 6 and the spacer 5 by the screw 6, so that the expansion card 1 is fixed.

[0021] Above, refer to Figures 1 to 3 The expansion card fixing mechanism according to the embodiment of the utility model is described, which can be applicable to expansion cards of different lengths and connectors of different connection heights, has wide applicability and simple structure.

[0022] It should be noted that, in this specification, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprises..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0023] Although the content of the utility model has been described in detail through the above preferred embodiments, it should be appreciated that the above description should not be considered as a limitation of the utility model. After reading the above content, various modifications and substitutions of the utility model will be obvious to those skilled in the art.
