[0030] Electronic components in electronic devices are fixed on circuit boards. However, due to the different sizes of these components, the fixing positions of the circuit boards vary, resulting in one type of circuit board corresponding only to one type of electronic component. This leads to poor versatility of the circuit boards. Correspondingly, refer to... Figure 1 , Figure 2 and Figure 4 This application provides a circuit board component 1, which includes a circuit board 11 and an expansion board 12. The circuit board 11 includes a first data interface 111, and a first side and a second side disposed along a first direction A opposite to the first data interface 111. The first data interface 111 is located on the second side and is used to fix the first end of a first electronic device 2. A first receiving gap is formed between the first data interface 111 and the fixing mating part 112 disposed on the first side along the first direction A. The expansion board 12 includes a third side and a fourth side disposed along the first direction A, and a first expansion fixing part is disposed on the third side. 121, the first expansion fixing part 121 is used to cooperate with the fixing mating part 112 to fix the expansion plate 12 on the circuit board 11. A second expansion fixing part 122 is provided on the fourth side. There is a second receiving gap along the first direction A between the first data interface 111 and the second expansion fixing part 122. The second receiving gap is smaller than the first receiving gap. When the first receiving gap is used to accommodate the first electronic device 2, the first expansion fixing part 121 is used to fix the second end of the first electronic device 2. When the second receiving gap is used to accommodate the first electronic device 2, the second expansion fixing part 122 is used to fix the second end of the first electronic device 2.

[0031] In this embodiment, the circuit board 11 includes a first data interface 111, and a first side and a second side are disposed along a first direction A opposite to the first data interface 111. Here, the first direction A can be the length direction of the circuit board 11 or the width direction of the circuit board 11. This embodiment does not limit the specific direction A. In one possible implementation provided by this embodiment, the first direction A is the length direction of the circuit board 11.

[0032] In this embodiment of the application, the first data interface 111 is used to fix the first end of the first electronic device 2. Here, it means that while the first data interface 111 is fixed to the first end of the first electronic device 2, the first data interface 111 is connected to the first end of the first electronic device 2 for data connection. In other words, the data of the first electronic device 2 can be transmitted to the circuit board 11 through the first data interface 111, and the data on the circuit board 11 can also be transmitted to the first electronic device 2 through the first data interface 111.

[0033] In this embodiment of the application, the first data structure is used to fix the end of the first electronic device 2. The first electronic device 2 can be a solid state disk (SSD), also known as a solid state drive, which is a hard disk made of solid state electronic storage chip array. Of course, the first electronic device 2 can be other types of electronic devices, and this embodiment of the application does not limit this. In one possible implementation of this application embodiment, the first electronic device 2 can be an M.2 interface solid-state drive. Here, it should be explained that the M.2 interface is a new host interface solution that is compatible with multiple communication protocols, such as SATA, PCIe, USB, HSIC, UART, SMBus, etc. The M.2 interface is a new generation interface standard tailored for ultrabooks to replace the original mSATA interface. Whether it is the smaller size or the higher transmission performance, M.2 is far superior to mSATA. The first electronic device 2 can be an M.2 interface solid-state drive with a width of 22 mm and a length of 80 mm, abbreviated as M.22280. The first electronic device 2 can also be an M.2 interface solid-state drive with a width of 22 mm and a length of 110 mm, abbreviated as M.222110.

[0034] In this embodiment of the application, there is a first accommodating gap between the first data interface 111 and the fixed mating part 112 provided on the first side along the first direction A, and there is a second accommodating gap between the first data interface 111 and the second extended fixing part 122 along the first direction A. The second accommodating gap is smaller than the first accommodating gap. Here, if the circuit board 1 is applicable to solid-state drives of both M.22280 and M.222110 sizes, the size of the first accommodating gap along the first direction A can be 110 mm, and the size of the second accommodating gap along the first direction A can be 80 mm.

[0035] In this embodiment, the first extension fixing part 121 is used to cooperate with the fixing mating part 112 to fix the extension plate 12 onto the circuit board 11. Here, the first extension fixing part 121 can cooperate with the fixing mating part 112 via a threaded connection to thread-fix the extension plate 12 onto the circuit board 11; or it can cooperate via a snap-fit ​​connection to snap-fix the extension plate 12 onto the circuit board 11. This embodiment does not limit the specific method used. In one possible implementation provided by this embodiment, the first extension fixing part 121 cooperates with the fixing mating part 112 via a snap-fit ​​connection. For example, the fixing mating part 112 has a columnar protrusion, and the first extension fixing part 121 has a through hole, with the columnar protrusion extending into the through hole.

[0036] In this embodiment, when the first accommodating gap is used to accommodate the first electronic device 2, the first extended fixing part 121 is used to fix it to the second end of the first electronic device 2. Here, the fixing method of the first extended fixing part 121 to the second end of the first electronic device 2 can be threaded fixing, snap-fit ​​fixing, or adhesive fixing. This embodiment does not limit the method. In one possible implementation provided by this embodiment, the fixing method of the first extended fixing part 121 to the second end of the first electronic device 2 is threaded fixing.

[0037] In this embodiment, when the second accommodating gap is used to accommodate the first electronic device 2, the second extended fixing part 122 is used to fix it to the second end of the first electronic device 2. Here, the fixing method of the second extended fixing part 122 to the second end of the first electronic device 2 can be threaded fixing, snap-fit ​​fixing, or adhesive fixing. This embodiment does not limit the method. In one possible implementation provided by this embodiment, the second extended fixing part 122 is fixed to the second end of the first electronic device 2 by threaded fixing.

[0038] In this embodiment of the application, a plurality of first data interfaces 111 and a plurality of expansion boards 12 can be correspondingly arranged on the circuit board 11 along the second direction B. Thus, the circuit board 11 can have a plurality of first accommodating gaps and a plurality of second accommodating gaps to accommodate a plurality of first electronic devices 2. Here, the second direction B is perpendicular to the first direction A. If the first direction A is the length direction of the circuit board 11, then the second direction B is the width direction of the circuit board 11.

[0039] The circuit board component 1 provided in this application embodiment adds an expansion board 12 to the circuit board 11. The first expansion fixing part 121 of the expansion board 12 is used to cooperate with the fixing mating part 112 of the circuit board 11 to fix the expansion fixing board on the circuit board 11, so that the expansion board 12 and the circuit board 11 are integrated. In this way, there is a first accommodating gap along the first direction A between the first data interface 111 on the circuit board 11 and the fixing mating part 112 provided on the first side, and there is a second accommodating gap along the first direction A between the first data interface 111 and the second expansion fixing part 122. The second accommodating gap is smaller than the first accommodating gap. When the first accommodating gap is used to accommodate the first electronic device 2, the first expansion fixing part 121 is used to fix the second end of the first electronic device 2. When the second accommodating gap is used to accommodate the first electronic device 2, the second expansion fixing part 122 is used to fix the second end of the first electronic device 2. Thus, the circuit board component 1 can be applied to at least two different sizes of the first electronic device 2 along the first direction A, and the versatility of the circuit board component 1 is enhanced.

[0040] Compared to related technologies where a circuit board 11 corresponds to only one size of electronic device, the circuit board 1 provided in this application embodiment, due to the addition of an expansion board 12 on the basis of the circuit board 11, makes the circuit board 1 applicable to at least two different sizes of the first electronic device 2 along the first direction A, thereby enhancing the versatility of the circuit board 1.

[0041] Reference Figure 5 and Figure 6This application provides a circuit board component 1, in which a first extended fixing part 121 and a second extended fixing part 122 have a first height, which is higher than the fixed height at which the first electronic device 2 is fixed to the circuit board 11.

[0042] In this embodiment, the first extended fixing part 121 and the second extended fixing part 122 have a first height, which is higher than the fixed height of the first electronic device 2 fixed to the circuit board 11. At this time, the first extended fixing part 121 and the second extended fixing part 122 can form a boss along the height direction C. The first extended fixing part 121 and the second extended fixing part 122 can also be a lifting rod. Of course, the first extended fixing part 121 and the second extended fixing part 122 can also be presented in other ways. The first extended fixing part 121 and the second extended fixing part 122 have a first height, which is higher than the fixed height of the first electronic device 2 fixed to the circuit board 11.

[0043] The circuit board component 1 provided in this application embodiment has a first extended fixing part 121 and a second extended fixing part 122 with a first height. The first height is higher than the fixed height of the first electronic device 2 fixed to the circuit board 11. In this way, when the second end of the first electronic device 2 is fixed with the first extended fixing part 121, the difficulty of the first extended fixing part 121 and the fixed mating part 112 is reduced.

[0044] Reference Figure 4 , Figure 5 and Figure 6 This application provides a circuit board component 1. A first extended fixing part 121 has a first boss 1211 formed along its height direction C and away from the circuit board 11. A second extended fixing part 122 has a second boss 1221 formed along its height direction C and away from the circuit board 11. The first boss 1211 or the second boss 1221 is used to be threadedly fixed to the second end of the first electronic device 2.

[0045] In this embodiment, the first extended fixing part 121 has a first boss 1211 formed along its height direction C and away from the circuit board 11, and the second extended fixing part 122 has a second boss 1221 formed along its height direction C and away from the circuit board 11. Here, it should be explained that the height of the first boss 1211 along its height direction C is the first height, and the height of the second extended fixing part 122 along its height direction C should also be the first height. In other words, the height of the first boss 1211 along its height direction is the same as the height of the second extended fixing part 122 along its height direction C.

[0046] In this embodiment, the first extended fixing part 121 has a plurality of first protrusions 1211 formed along its height direction C and away from the circuit board 11. The plurality of first protrusions 1211 are distributed along the second direction B. Here, the second direction B is perpendicular to the first direction A. For example, the first direction A is the length direction of the circuit board 11 and the second direction B is the width direction of the circuit board 11. When the first extended fixing part 121 is used to fix the second end of the first electronic device 2, the plurality of first protrusions 1211 can all be used to thread-fix the second end of the first electronic device 2. In this way, the fixing reliability of the first extended fixing part 121 to the second end of the first electronic device 2 can be improved.

[0047] In this embodiment, the second extended fixing part 122 has a plurality of second protrusions 1221 formed along its height direction C and away from the circuit board 11. The plurality of second protrusions 1221 are distributed along the second direction B, where the second direction B is perpendicular to the first direction A. For example, the first direction A is the length direction of the circuit board 11 and the second direction B is the width direction of the circuit board 11. When the second extended fixing part 122 is used to fix the second end of the first electronic device 2, the plurality of second protrusions 1221 can all be used to thread-fix the second end of the first electronic device 2. In this way, the fixing reliability of the second extended fixing part 122 to the second end of the first electronic device 2 can be improved.

[0048] The circuit board component 1 provided in this application embodiment has a first boss 1211 formed in the first extended fixing part 121 along its height direction C and away from the circuit board 11, and a second protrusion formed in the second extended fixing part 122 along its height direction C and away from the circuit board 11. The first boss 1211 or the second boss 1221 is used to be threadedly fixed to the second end of the first electronic device 2. This has the technical effect of simple structure and easy implementation.

[0049] Reference Figure 4 , Figure 5 and Figure 6This application provides a circuit board component 1. A first boss 1211 has a first threaded hole 12111 along the height direction C of the first extended fixing portion 121. The circuit board component 1 also includes a first threaded connector 13, which includes a first connecting portion and a first limiting portion. Along the radial direction of the first threaded hole 12111, the size of the first limiting portion is larger than the size of the first connecting portion. A second boss 1221 has a second threaded hole 12211 along the height direction C of the second extended fixing portion 122. The circuit board component 1 also includes a second threaded connector 14, which includes a second connecting portion and a second limiting portion. Along the radial direction of the second threaded hole 12211, the size of the second limiting portion is larger than the size of the second connecting portion. When the first boss 1211 and the first electronic device 2... When both ends are fixed, the first part of the first connecting part extends into the first threaded hole 12111 and is fixed to the first boss 1211. The second part of the first connecting part is used to abut against the second end of the first electronic device 2. The first limiting part is used to abut against and limit the second end of the first electronic device 2 along the axial direction of the first threaded hole 12111 and away from the circuit board 11. When the second boss 1221 is used to fix the second end of the first electronic device 2, the first part of the second connecting part extends into the second threaded hole 12211 and is fixed to the second boss 1221. The outer contour of the second part of the second connecting part is used to abut against the second end of the first electronic device 2. The second limiting part is used to abut against and limit the second end of the first electronic device 2 along the axial direction of the second threaded hole 12211 and away from the circuit board 11.

[0050] In this embodiment, the first boss 1211 has a first threaded hole 12111 along the height direction C of the first extended fixing part 121. Here, the first threaded hole 12111 can be formed by directly opening the first boss 1211 along the height direction C of the first extended fixing part 121. Of course, the first threaded hole 12111 can also be formed by first opening a first through hole in the first boss 1211 along the height direction C of the first extended fixing part 121, and then embedding a first threaded nut in the first through hole. This embodiment does not limit this.

[0051] In this embodiment, the second boss 1221 has a second threaded hole 12211 along the height direction C of the second extended fixing part 122. Here, the second threaded hole 12211 can be formed by directly opening the second boss 1221 along the height direction C of the second extended fixing part 122. Of course, the second threaded hole 12211 can also be formed by opening a second through hole 122111 on the second boss 1221 along the height direction C of the second extended part, and embedding a second threaded nut 122112 in the second through hole 122111. This embodiment does not limit this.
