[0040] Please see Figure 1 . Figure 1 This is a perspective view of the motherboard assembly 1 and circuit board 2 in one embodiment of this application.
[0041] Motherboard assembly 1 supports a circuit board 2, wherein the circuit board 2 is, for example, but not limited to, a PCIe expansion card. Motherboard assembly 1 includes a motherboard 10 and a mounting bracket 20. Motherboard 10 includes a substrate 11 and an electrical connector 12, the electrical connector 12 being disposed on the substrate 11 and used for insertion of the circuit board 2. Mounting bracket 20 includes at least one limiting bracket 21. Limiting bracket 21 includes a base 211 and a resilient limiting portion 212. Base 211 is disposed on substrate 11 and located on one side of electrical connector 12. Resilient limiting portion 212 is movably erected on base 211. Resilient limiting portion 212 includes a stop structure 2121, and the stop structure 2121 is used to stop the side of circuit board 2 away from electrical connector 12.
[0042] Next, please refer to Figure 2 and Figure 3 . Figure 2 for Figure 1 An exploded view of motherboard component 1 from one perspective. Figure 3 for Figure 1 An exploded view of motherboard component 1 from another perspective.
[0043] In one embodiment, the retaining bracket 21 is, for example, a one-piece molded part, and is made of, for example, plastic. In one embodiment, there are two retaining brackets 21, with the base 211 of one and the base 211 of the other located on opposite sides of the electrical connector 12. The two retaining brackets 21 have the same structure, so the following paragraphs will only describe the structure of one of the retaining brackets 21 in detail.
[0044] In one embodiment, the substrate 11 includes, for example, two first positioning structures 111 and two locking holes 112. The two first positioning structures 111 are, for example, positioning holes, and are respectively located on opposite sides of the electrical connector 12. The two locking holes 112 are also respectively located on opposite sides of the electrical connector 12, and are respectively located next to the two first positioning structures 111.
[0045] In one embodiment, the base 211 of the limiting frame 21 includes, for example, a second positioning structure 2111 and a through hole 2112, wherein the second positioning structure 2111 is, for example, a positioning post. The second positioning structures 2111 of the bases 211 of the two limiting frames 21 are respectively matched with the two first positioning structures 111 of the substrate 11. The two through holes 2112 are respectively aligned with the two locking holes 112 of the substrate 11.
[0046] In one embodiment, the motherboard assembly 1 may further include two locking fasteners 30. The two locking fasteners 30 pass through two through holes 2112 and are locked into two locking holes 112, thereby fixing the two limiting brackets 21 to the base plate 11 of the motherboard 10.
[0047] In the above embodiments, the combination of the two first positioning structures 111 and the two second positioning structures 2111 can help the two limiting frames 21 be positioned on the substrate 11 of the main board 10 before the two locking fasteners 30 fix the two limiting frames 21 to the substrate 11 of the main board 10, so that the through holes 2112 of the base 211 of the two limiting frames 21 are respectively aligned with the two locking holes 112 of the substrate 11 of the main board 10.
[0048] It should be noted that the two first positioning structures 111 and the two second positioning structures 2111 are optional structures and can be omitted. Furthermore, the locking hole 112 of the substrate 11, the through hole 2112 of the base 211 of the two limiting brackets 21 and the locking fastener 30 are optional structures and components and can be omitted. The two limiting brackets 21 can be fixed to the substrate 11 of the main board 10 in other ways, such as by welding or bonding.
[0049] In one embodiment, the limiting frame 21 may further include a fixing part 213 connected to the base 211, and an elastic limiting part 212 for detachably locking to the fixing part 213. In one embodiment, the elastic limiting part 212 includes an inclined section 2122, a vertical section 2123, and a horizontal section 2124 connected in sequence. The inclined section 2122 is connected to the base 211, the stop structure 2121 is located in the vertical section 2123, and the horizontal section 2124 is detachably locked to the fixing part 213. In one embodiment, the horizontal section 2124 of the elastic limiting part 212 includes a locking structure E, and the fixing part 213 includes a slot S. The locking structure E is detachably locked to the slot S of the fixing part 213.
[0050] Next, please refer to Figure 4 , Figure 4 for Figure 1 A side view of the limiting frame 21. In one embodiment, the upright section 2123 of the elastic limiting portion 212 of the limiting frame 21 includes a limiting groove P. The limiting groove P is closer to and extends toward the base 211 of the limiting frame 21 than the stop structure 2121, and is used to limit the circuit board 2. In one embodiment, the limiting groove P includes at least one wide segment P1 and one narrow segment P2 connected together, wherein the width D1 of the wide segment P1 is greater than the width D2 of the narrow segment P2. In one embodiment, the limiting groove P has two wide segments P1, and the narrow segment P2 is located between the two wide segments P1.
[0051] Next, the process of assembling circuit board 2 onto motherboard assembly 1 will be described below. Figures 5 to 6 The process of assembling circuit board 2 onto motherboard assembly 1 is illustrated.
[0052] First, such as Figure 5 As shown, first, the elastic limiting parts 212 of the two limiting brackets 21 are in the released position. At this time, the two elastic limiting parts 212 elastically deform, and the locking structure E of the horizontal section 2124 of the two elastic limiting parts 212 is respectively locked into the slots S of the two fixing parts 213. Then, the circuit board 2 is vertically inserted into the electrical connector 12 of the main board 10.
[0053] Next, as Figure 6 As shown, the locking structures E of the horizontal segments 2124 of the two elastic limiting parts 212 are respectively released from the slots S of the two fixing parts 213, so that the two elastic limiting parts 212 spring back and move from the released position to the stop position. At this time, the stop structures 2121 of the two elastic limiting parts 212 stop the two opposite corners of the circuit board 2 away from the electrical connector 12. In this way, the assembly of the circuit board 2 onto the motherboard assembly 1 is completed.
[0054] In the above embodiments, the base 211 of at least one limiting bracket 21 is disposed on the substrate 11 and located on one side of the electrical connector 12. The elastic limiting part 212 of the limiting bracket 21 is movably erected on the base 211, and the stop structure 2121 of the elastic limiting part 212 is used to stop the circuit board 2 from the side away from the electrical connector 12. This allows the fixed bracket 20 to be fixedly and vertically inserted into the circuit board 2 of the motherboard 10, so as to ensure that the vertical circuit board 2 can still be properly inserted into the electrical connector 12 of the motherboard 10 even if it is subjected to external force.
[0055] In the above embodiment, by means of the bases 211 of the two limiting brackets 21 being located on opposite sides of the electrical connector 12, and the stop structures 2121 of the two elastic limiting parts 212 stopping the circuit board 2 on the opposite two corners away from the electrical connector 12, the fixing bracket 20 can more stably fix the circuit board 2 that is vertically inserted into the motherboard 10.
[0056] It should be noted that the number of limit brackets 21 is not limited to two. If one limit bracket 21 is sufficient to stabilize the circuit board 2, the number of limit brackets 21 can be adjusted to one.
[0057] In the above embodiment, the circuit board 2 can be limited by the narrow section P2 of the limiting groove P of the two limiting brackets 21 to prevent the circuit board 2 from shaking.
[0058] It should be noted that the limiting grooves P of the two limiting frames 21 are optional structures, and may be omitted in other embodiments.
[0059] When it is necessary to separate the circuit board 2 from the motherboard 10, the elastic limiting portions 212 of the two limiting brackets 21 are in the released position (e.g., Figure 5 As shown, this allows the stop structures 2121 of the two elastic limiting parts 212 to separate from the side of the circuit board 2 away from the electrical connector 12. At this time, the circuit board 2 can be directly separated from the electrical connector 12 without being stopped by the stop structures 2121.
[0060] It should be noted that the fixing part 213 of the limiting frame 21 is an optional structure and can be omitted in other embodiments. Correspondingly, the locking structure E of the elastic limiting part 212 of the limiting frame 21 can be omitted. Thus, when assembling or disassembling the circuit board 2, the elastic limiting part 212 of the limiting frame 21 must be held in the released position by hand.
[0061] Furthermore, the structure of the elastic limiting part 212 of the aforementioned limiting frame 21 is merely exemplary and can be adjusted as needed.
[0062] According to the fixed bracket and motherboard assembly disclosed in the above embodiments, the base of the limiting bracket is disposed on the substrate and located on one side of the electrical connector. The elastic limiting part of the limiting bracket is movably erected on the base, and the stop structure of the elastic limiting part is used to stop the circuit board from being disposed on the side away from the electrical connector. This allows the fixed bracket to be fixedly and vertically inserted into the circuit board of the motherboard, ensuring that the vertical circuit board can still be properly inserted into the electrical connector of the motherboard even if it is subjected to external force.
[0063] In one embodiment of this application, the fixed bracket and motherboard assembly of this application can be disposed in a server, which can be used for artificial intelligence (AI) computing, edge computing, or as a 5G server, cloud server or vehicle networking server.
[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
