The motherboard has multiple interfaces. For example, the interface can be M.2&x16 interface. When using the motherboard for product testing, for example, the product can be a memory, and the product needs to be frequently inserted into the interface or unplugged from the interface.

In order to ensure that the product can be removed and plugged in smoothly, the motherboard generally needs to be fixed. In this regard, in the related art, a single-layer rack is provided. The single-layer rack is placed on the desktop, and the motherboard is fixed on the single-layer rack, thereby achieving the fixation of the motherboard.

When conducting product testing, it is generally necessary to use multiple motherboards at the same time to meet testing needs. Therefore, it is necessary to set up multiple single-layer racks at the same time, and fix a motherboard on one rack to meet the fixing needs of each motherboard. However, since multiple single-layer racks are placed side by side, space will be wasted in the horizontal direction.

Based on this, as shown in FIG. 1 , some embodiments of the present disclosure provide a host assembly 1 , which includes a superimposed mainboard fixing device 11 and a mainboard 12 . The mainboard 12 is fixed on the superimposed mainboard fixing device 11 . In this way, the superimposed motherboard fixing device 11 can fix the motherboard 12 to ensure the stability of the motherboard 12 and ensure that the product can be inserted into the interface smoothly or pulled out from the interface.

It can be understood that the above-mentioned stacked mainboard fixing device 11 can be placed on the ground or on a desktop, and the disclosure does not specifically limit this.

The bearing member 111 includes a fixing plate 1111 and a support portion 1112 connected to the bottom surface of the fixing plate 1111 . A main board 12 is connected to the top surface of the plate 1111; along the thickness direction of the fixed plate 1111 (the X direction in Figure 1), a plurality of bearing members 111 are arranged in sequence.

It can be understood that, as shown in FIG. 1 , the fixing plate 1111 has a top surface T and a bottom surface B arranged oppositely, wherein the top surface T of the fixing plate 1111 is a surface used to connect to the main board 12 , and the bottom surface B of the fixing plate 1111 It is the surface for connecting the support part 1112.

In some examples, multiple motherboards 12 are provided, and one motherboard 12 is connected to one fixed plate 1111 .

For example, the multiple motherboards 12 may be of different types, or may be the same.

For example, the dimensions of the multiple mainboards 12 may be different. For example, when the mainboard 12 has a rectangular parallelepiped structure, the length, width and height of different mainboards 12 are not equal.

Alternatively, the dimensions of the multiple motherboards 12 may be the same.

For example, the number of fixing boards 1111 and the main board 12 may be equal.

Alternatively, the number of the fixed plates 1111 and the main board 12 may also be unequal. Some of the plurality of fixed plates 1111 have the main board 12 fixed on them, while other parts do not have the main board 12 fixed on them. Specific settings can be made according to needs.

In some examples, 2, 3, 4 or 5 of the above-mentioned bearing members 111 may be provided. The present disclosure does not specifically limit the number of bearing members 111 .

For example, as shown in Figure 1, three of the above-mentioned bearing members 111 are provided, that is, three motherboards 12 can be fixed at the same time. This can not only meet the basic testing requirements for the product, but also avoid excessive height of the superimposed motherboard fixing device 11.

Of course, two adjacent bearing members 111 may also contact each other. For example, among two adjacent bearing members 111 , the support portion 1112 of the upper bearing member 111 is in contact with the fixing plate 1111 of the lower bearing member 111 . This can save the space of the stacked motherboard fixing device 11 in the X direction.

In some examples, the above-mentioned fixed plate 1111 may be a square plate, a circular plate or an irregularly shaped plate.

The support portion 1112 on the bearing member 111 can provide support for the fixed plate 1111, and the main board 12 can be fixed on the fixed plate 1111 to achieve stable placement of the main board 12.

Since there are multiple carriers 111 , and the fixing plate 1111 on each carrier 111 can fix one mainboard 12 , multiple mainboards 12 can be fixed at the same time.

In addition, since the plurality of bearing members 111 are arranged sequentially along the X direction, the horizontal space occupied by the plurality of bearing members 111 is consistent with the horizontal space occupied by one bearing member 111, so space in the horizontal direction can be saved.

In addition, the main board 12 is exposed to the outside. Therefore, when conducting product testing, compared with using a closed host to test the product in some related technologies, when using the motherboard 12 to conduct product testing, there is no constraint of a closed host shell, which is more convenient. In addition, the motherboard 12 is smaller in size than a closed host, which can further save space.

In this case, for example, both support sub-boards A1 are connected to the fixing plate 1111 through screws. For example, a supporting sub-board A1 is connected to the fixing plate 1111 through a screw.

Among them, the two supporting sub-boards A1 and the connecting sub-boards A2 can be integrally formed, which can increase the connection strength between them and avoid secondary processing.

Alternatively, the two support sub-boards A1 and the connection sub-board A2 can also have a separate structure. The support sub-board A1 and the connection sub-board A2 can be processed separately, and then the connection sub-board A2 and the support sub-board can be connected by welding or other suitable methods. A1 is connected together.

In other examples, the support portion 1112 and the fixing plate 1111 can also be detachably connected together by snapping.

In other embodiments, the support part 1112 and the fixing plate 1111 can also be formed into an integral structure, which can avoid secondary processing and later assembly, and can also improve the overall structural strength of the support part 1112 and the fixing plate 1111.
