Figure 2 Shows Figure 1 A partial three-dimensional schematic diagram of the server in another viewing angle in the illustrated embodiment. Figure 3 Shows Figure 2 An exploded view of the expansion module separated from the mainboard in the embodiment shown.

[0047] In this embodiment, the server 1 includes a housing 10 and an electronic module 20.

[0049] The motherboard 21 has a carrying surface 211 and an electrical connector 212. In addition, the motherboard 21 may also have a plurality of electronic components 213, such as but not limited to capacitors, resistors, and another electrical connector smaller than the electrical connector 212. The electrical connector 212 and the electronic components 213 are both located on the carrying surface 211 of the motherboard 21, and the electronic components 213 are located around the electrical connector 212.

[0050] The guide seat 22 includes a seat body 221 and a plurality of guide structures 222. The seat body 221 is fixed to the bearing surface 211 of the motherboard 21 by screws or clamping, for example, and is located around the electrical connector 212 and surrounds the electrical connector 212. The seat body 221 has an opening 2211, a plurality of clearance holes 2212, a wire management structure 2213 and two card slots 2214. The opening 2211 reveals the electrical connector 212, and these clearance holes 2212 respectively accommodate these electronic components 213 of the motherboard 21. The wire management structure 2213 is located next to the opening 2211 and is used to organize cables (not shown). The purpose of the card slot 2214 will be described in detail in the subsequent paragraphs. These guide structures 222 protrude from the seat body 221 and are farther away from the bearing surface 211 of the motherboard 21 than the electrical connector 212. That is, the height H1 of the guide structures 222 relative to the bearing surface 211 of the motherboard 21 is greater than the height H2 of the electrical connector 212 relative to the bearing surface 211 of the motherboard 21 (please refer to Figure 7 ). Two of the guide structures 222 are located on one side of the long axis L of the electrical connector 212 and are opposite to each other, and the other two guide structures 222 are located on the other side of the long axis L of the electrical connector 212 and are opposite to each other. Each of these guide structures 222 has a guide slope 2221, and the purpose of the guide slope 2221 will be described in detail later.

[0051] It should be noted that the clearance hole 2212 and the wire management structure 2213 are optional structures. If there is no electronic component or cable at the place where the seat is placed, the clearance hole and the wire management structure can be omitted.

[0052] Next, please also refer to Figure 3 , 5 and Figure 6 . Figure 5 Shows Figure 1 A three-dimensional schematic diagram of a circuit board seat and a circuit board of an expansion assembly in the illustrated embodiment. Figure 6 Shows Figure 5 A schematic cross-sectional view of a circuit board seat and a circuit board of an expansion assembly in the illustrated embodiment.

[0053] The expansion component 23 is, for example but not limited to, a hard disk component. The expansion component 23 includes a circuit board seat 231, a circuit board 232, and at least one electronic device 233 (such as Figure 1 The circuit board seat 231 includes a carrying portion 2311 , two guiding portions 2312 , two hook portions 2313 , a partition portion 2314 and a connecting portion 2315 .

[0054] The bearing portion 2311 has an operating hole 23111. Two guide portions 2312 protrude from one side of the bearing portion 2311 and are separated from each other, and each of the two guide portions 2312 has a guide slope 23121. Two hook portions 2313 are connected to the bearing portion 2311 and are separated from each other. The two hook portions 2313 have the same structure, so the structure of only one of the hook portions 2313 is described in detail below. The hook portion 2313 includes an elastic arm 23131, a block 23132 and an operating handle 23133. The elastic arm 23131 has a first end 23131a and a second end 23131b opposite to each other. The first end 23131a of the elastic arm 23131 is connected to the bearing portion 2311. The operating handle 23133 has a first end 23133a and a second end 23133b opposite to each other. The first end 23133a of the block 23132 and the operating handle 23133 are respectively connected to different sides of the second end 23131b of the elastic arm 23131. The second end 23133b of the operating handle 23133 is farther away from the block 23132 than the first end 23131a of the elastic arm 23131. One end of the partition 2314 is detachably mounted on the supporting portion 2311 through the coupling portion 2315. The partition 2314 has a hook structure 23141 and a plurality of separation grooves 23142. The hook structure 23141 is located at one end of the partition 2314 away from the coupling portion 2315 and corresponds to the operating hole 23111 of the supporting portion 2311, and the separation grooves 23142 are located between the opposite ends of the partition 2314.

[0055] In this embodiment, the circuit board seat 231 is made by double injection molding, for example, the supporting portion 2311, the guiding portion 2312, the hook portion 2313 and the partition portion 2314 of the circuit board seat 231 are made of plastic material, and the connecting portion 2315 of the circuit board seat 231 is made of rubber material. In this way, the assembly process and the number of parts of the circuit board seat 231 can be reduced. It should be noted that the manufacturing method and material of the circuit board seat 231 are not used to limit the present invention, but can be adjusted according to needs.

[0056] The circuit board 232 is fixed on the supporting portion 2311 of the circuit board seat 231, and the hook structure 23141 of the partition portion 2314 of the circuit board seat 231 passes through the circuit board 232 and is fixed to the circuit board 232. The operation hole 23111 of the supporting portion 2311 allows the user to use a tool or finger to pull the hook structure 23141 to release the hook structure 23141 from the circuit board 232.

[0057] The circuit board 232 has a plug-in portion 2321, a plurality of slots 2322, and a plurality of light-emitting elements 2323. The plug-in portion 2321 of the circuit board 232 is, for example, a gold finger. The plug-in portion 2321 of the circuit board 232 and the guide portion 2312 of the circuit board seat 231 both protrude from the same side of the carrier portion 2311, and the length L1 of the plug-in portion 2321 protruding from the carrier portion 2311 is less than the length L2 of the guide portion 2312 protruding from the carrier portion 2311 (please refer to the embodiment of the present invention). Figure 7 ). The slots 2322 are for inserting electronic devices 233, wherein the electronic devices 233 are, for example, hard disks. The light-emitting elements 2323 are used, for example, to display the status of the electronic devices 233, such as the operating status of the electronic devices 233. The light-emitting elements 2323 are respectively located in the partition grooves 23142 of the partition portion 2314 of the circuit board seat 231, so that the light emitted by the light-emitting elements 2323 does not interfere with each other.

[0058] It should be noted that the circuit board 232 is not limited to having the light emitting member 2323. In other embodiments, the circuit board may not have a light emitting member. In such a configuration, the partitioning portion and the combining portion of the circuit board seat may be omitted.

[0059] Next, the process of plugging the circuit board 232 of the expansion assembly 23 into the electrical connector 212 of the motherboard 21 will be described in detail below. Figures 7 to 10 , Figures 7 to 10 Shows Figure 3 The process of assembling the expansion component to the motherboard in the embodiment shown.

[0060] like Figure 7 and Figure 8 As shown, in the process of plugging the circuit board 232 of the expansion component 23 toward the electrical connector 212 of the mainboard 21, the expansion component 23 may be offset along the long axis L (such as direction A) and the short axis S (such as direction B) of the electrical connector 212, so that the expansion component 23 is not plugged in a manner that is directly facing the electrical connector 212 of the mainboard 21.

[0061] like Fig. 9 and Fig.10As shown, although the expansion assembly 23 is offset relative to the electrical connector 212, during the process of plugging the circuit board 232 of the expansion assembly 23 into the electrical connector 212 of the motherboard 21, the guide portion 2312 of the circuit board seat 231 is guided by the guide slope 2221 of the guide structure 222 of the guide seat 22 and moves in the opposite direction of direction B (such as direction D), and the guide slope 23121 of the guide portion 2312 of the circuit board seat 231 is abutted by the seat body 221 and moves in the opposite direction of direction A (such as direction C), thereby guiding the circuit board 232 to the electrical connector 212, so that the plug-in portion 2321 of the circuit board 232 is accurately inserted into the electrical connector 212. At this time, the block 23132 of the hook portion 2313 of the circuit board 232 is inserted into the slot 2214 of the seat body 221 of the guide seat 22, so as to prevent the circuit board 232 from being detached from the electrical connector 212 of the motherboard 21. In this way, the operation of plugging the circuit board 232 of the expansion component 23 into the electrical connector 212 of the mainboard 21 is completed.

[0062] When the expansion assembly 23 is to be disassembled, the operating handle 23133 of the hook portion 2313 of the circuit board seat 231 can be pressed to drive the elastic arm 23131, so that the block 23132 is separated from the slot 2214 of the seat body 221 of the guide seat 22. In this way, the expansion assembly 23 can be pulled upward from the main board 21.

[0063] In the present embodiment, the seat body 221 of the guide seat 22 is disposed around the electrical connector 212 of the motherboard 21, the guide seat 22 has a guide structure 222 protruding from the seat body 221, and the circuit board seat 231 includes a guide portion 2312. In the process of plugging the circuit board 232 of the expansion component 23 into the electrical connector 212 of the motherboard 21, the circuit board seat 231 of the expansion component 23 is guided by the guide inclined surface 2221 of the guide structure 222 of the guide seat 22, and the guide inclined surface 23121 of the guide portion 2312 of the circuit board seat 231 is abutted by the seat body 221, so as to correct the deviation of the expansion component 23 in multiple directions (such as the deviation on the short axis S and the long axis L of the electrical connector 212 of the motherboard 21), so as to guide the circuit board 232 to the electrical connector 212, so that the circuit board 232 can be plugged into the electrical connector 212 in a correct path. In this way, the chance of the expansion component 23 colliding with the electrical connector 212 and the surrounding electronic components 213 can be reduced, thereby preventing the motherboard 21 from being damaged during the insertion of the circuit board 232 of the expansion component 23 .

[0064] It should be noted that the guiding structure 222 of the guiding seat 22 is not limited to guiding the offset of the expansion component 23 on the short axis S of the electrical connector 212 of the main board 21 with the guiding inclined surface 2221, and the guiding portion 2312 of the circuit board seat 231 is not limited to guiding the offset of the expansion component 23 on the long axis L of the electrical connector 212 of the main board 21 with the guiding inclined surface 23121. In other embodiments, the guiding structure of the guiding seat and the guiding portion of the circuit board can guide the circuit board seat with an arc surface.

[0065] On the other hand, by configuring the guide structure 222 of the guide seat 22 to be farther away from the bearing surface 211 of the motherboard 21 than the electrical connector 212 of the motherboard 21, and the length L1 of the plug-in portion 2321 of the circuit board 232 protruding from the bearing portion 2311 of the circuit board seat 231 to be less than the length L2 of the guide portion 2312 protruding from the bearing portion 2311, it is possible to ensure that the guide portion 2312 of the circuit board seat 231 of the expansion component 23 first abuts against the guide structure 222 before the circuit board 232 contacts the electrical connector 212 of the motherboard 21, so that the guide structure 222 guides the circuit board 232 to the correct plug-in path, thereby further reducing the chance of the expansion component 23 colliding with the electrical connector 212 and the electronic components around it.

[0066] It should be noted that the guide structure 222 of the guide seat 22 is not limited to being farther from the bearing surface 211 of the motherboard 21 than the electrical connector 212 of the motherboard 21, and the length L1 of the plug-in portion 2321 of the circuit board 232 protruding from the bearing portion 2311 of the circuit board seat 231 is not limited to being less than the length L2 of the guide portion 2312 protruding from the bearing portion 2311. In other embodiments, the guide structure of the guide seat may be flush with the electrical connector of the motherboard, and the plug-in portion of the circuit board may be flush with the guide portion of the circuit board seat.

[0067] It should be noted that the number of the guiding structures 222 of the guiding seat 22 and the guiding portions 2312 of the circuit board seat 231 is not intended to limit the present invention, but can be increased or decreased according to needs.

[0068] In this embodiment, the circuit board 232 is fixed to the motherboard 21 by the hook portion 2313 of the circuit board holder 231 being fixed in the slot 2214, rather than by the anti-tripping mechanism of the electrical connector 212 integrated into the motherboard 21. Therefore, when the electrical connector 212 of the motherboard 21 is damaged, only the electrical connector 212 needs to be replaced, and the process and parts required for replacing the anti-tripping mechanism are omitted.

[0069] On the other hand, the hook portion 2313 of the circuit board seat 231 is an optional structure. In other embodiments, the circuit board seat may not have a hook portion, and the seat body of the guide seat may correspondingly not have a slot. In such a configuration, the expansion component and the motherboard can be fixed only by the friction between the circuit board plugged into the electrical connector.

[0070] According to the electronic module and server provided by the above-mentioned embodiment, the guide seat body is arranged around the electrical connector of the motherboard, the guide seat has a guide structure protruding from the seat body, and the circuit board seat includes a guide portion. In the process of plugging the circuit board of the expansion assembly into the electrical connector of the motherboard, the circuit board seat of the expansion assembly is guided by the guide slope of the guide structure of the guide seat, and the guide slope of the guide portion of the circuit board seat is abutted by the seat body, so as to correct the deviation of the expansion assembly in multiple directions (such as the deviation on the short axis and long axis of the electrical connector of the motherboard), so as to guide the circuit board to the electrical connector, so that the circuit board can be plugged into the electrical connector in a correct path. In this way, the chance of the expansion assembly colliding with the electrical connector and the electronic components around it can be reduced, so as to prevent the motherboard from being damaged during the process of plugging the circuit board of the expansion assembly.

[0071] Furthermore, in addition to the guiding structure of the guide seat to correct the offset of the expansion component on the short axis of the electrical connector of the motherboard, the guiding portion of the circuit board seat also corrects the offset of the expansion component on the long axis of the electrical connector of the motherboard. Therefore, the guiding structure of the guide seat and the guiding portion of the circuit board seat can provide multi-directional offset correction for the expansion component, which can further reduce the chance of the expansion component colliding with the electrical connector and the electronic components around it.

[0072] In addition, by configuring the guide structure of the guide seat to be farther away from the bearing surface of the motherboard than the electrical connector of the motherboard, and the length of the plug-in portion of the circuit board protruding from the bearing portion of the circuit board seat to be shorter than the length of the guide portion protruding from the bearing portion, it is possible to ensure that the guide portion of the circuit board seat of the expansion component first abuts against the guide structure before the circuit board contacts the electrical connector of the motherboard, so that the guide structure guides the circuit board to the correct plug-in path, thereby further reducing the chance of the expansion component colliding with the electrical connector and the electronic components around it.

[0073] In this embodiment, the server of the present invention can be used for artificial intelligence (AI) computing, edge computing, and can also be used as a 5G server, a cloud server, or an Internet of Vehicles server.

[0074] Although the present invention is disclosed as above with the aforementioned preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the patent protection scope of the present invention shall be determined by the scope of the claims attached to this specification.
