In practice, servers typically have multiple PCBs. When setting up a server, upgrading it, or maintaining it, bolting the boards is time-consuming, labor-intensive, and inefficient, and no longer meets the needs for rapid assembly and disassembly of PCBs in certain business scenarios. Summary of the Invention
[0003] The embodiment of the present application provides an electronic device, which makes disassembly and assembly of a circuit board and a chassis more convenient and quick, saving time and effort.
[0004] An electronic device is proposed, comprising a chassis, a circuit board, a CPU, a support member, and a connector. The CPU is disposed on the circuit board, and the connector extends through the circuit board and is fixedly connected to the circuit board. The support member is detachably disposed within the chassis, and is provided with a first fixing portion adapted to mate with the connector. The connector is detachably connected to the first fixing portion. The connector secures the circuit board via a detachable connection between the support member and the chassis, eliminating the need for screwing. This simple and flexible operation saves time, particularly when a large number of circuit boards need to be secured to the chassis. This significantly reduces time costs and significantly improves work efficiency.
[0005] In one possible embodiment, multiple connectors are provided, the circuit board is provided with multiple through-holes, and multiple first fixing portions are provided. The multiple connectors pass through the multiple through-holes one by one and are connected to the multiple first fixing portions in a one-to-one correspondence. This one-to-one correspondence between the multiple connectors and the multiple first fixing portions can achieve rapid assembly and disassembly of the circuit board.
[0006] In one possible embodiment, each connector includes a welding portion disposed within the through-hole and secured thereto by welding; and a connecting portion located outside the through-hole, one end of which is connected to the welding portion and the other end of which is detachably connected to the first securing portion. The welding portion can be secured by welding within the through-hole, while the connecting portion is detachably connected to the first securing portion, making it more convenient to use.
[0007] In a possible implementation manner, the welding portion and the through hole are welded using a reflow process.
[0008] In one possible embodiment, the edge of the connecting portion has a flange; the connecting member is detachably connected to the first fixing portion via the flange. The flange provided on the connecting member can be locked in the first fixing portion, which can improve the stability of the suspended circuit board and prevent it from falling off.
[0009] In one possible embodiment, the first fixing portion is any one of a through hole, a groove, a quick-connect socket, an elastic buckle, and a protrusion. Any of these can be used as a connection method between the first fixing portion and the connecting portion, and the method can be selected based on actual needs.
[0010] In a possible implementation manner, the connecting portion is provided with an elastic sheet, and the connecting portion is elastically connected to the first fixing portion via the elastic sheet.
[0011] In a possible implementation, the connecting portion is a quick-connect connector, and the connecting portion is plugged into the first fixing portion via the quick-connect connector.
[0012] In one possible embodiment, a CPU bracket is further provided on the circuit board. The CPU bracket is used to support the CPU on the circuit board. The CPU bracket includes an upper CPU bracket and a lower CPU bracket, each located on either side of the circuit board. The CPU bracket is used to support the CPU on the circuit board. Using the CPU bracket as support in its location effectively improves the stability of the CPU and alleviates stress concentration near the CPU.
[0013] In one possible embodiment, the support member has at least one raised portion that abuts the CPU lower bracket. The support member uses the raised portion to abut the CPU lower bracket, and the support member can relieve stress near the CPU through the CPU lower bracket in contact with the support member, thereby improving the stability of the CPU.

[0019] For example, in electronic equipment, servers are used in certain business scenarios, such as server spare parts maintenance, production installation, or mass production of models. Production efficiency and time cost control requirements are very high. In this context, services such as server maintenance are required to save time and improve efficiency as much as possible. In the existing technology, the circuit board is usually fixed to the backing plate with screws, and the backing plate and the chassis are fixed with nails (see Figure 1 Although this solution achieves quick fixation between the liner and the chassis, the circuit board still needs to be installed on the liner, and the installation efficiency is not high.
[0020] Therefore, an embodiment of the present application proposes a fixing device for a circuit board of an electronic device, so as to make the assembly and disassembly of the circuit board more convenient, quick, and time-saving and labor-saving.
[0021] Figure 2 This is a cross-sectional structural diagram of the connection relationship between a circuit board, a connector, and a support member proposed in an embodiment of the present application. Figure 2 As shown, the electronic device includes a chassis 3, a circuit board 2, a CPU, and a connector 1. The connector 1 includes a welding portion 5 and a connecting portion 4. The CPU is disposed on the circuit board 2. The connector 1 passes through the circuit board 2 and is fixedly connected to the circuit board 2. A first fixing portion adapted to the connector 1 is disposed on the bottom of the chassis 3, and the connector 1 is detachably connected to the first fixing portion. For example, the connector 1 can be a hanging nail, and the first fixing portion can be a through-hole. The hanging nail is fixedly connected to the chassis 3 through the through-hole. Optionally, a flange 8 can be provided on the edge of the connecting portion 4. The flange 8 has good stability at the connection with the through-hole, making it difficult for the connecting portion 4 to fall off from the through-hole.
[0022] For example, the connector 1 can also be connected to the first fixing portion by plugging, snapping, elastic connection, etc. to achieve quick disassembly, thereby improving assembly efficiency. For example, the connector 1 can be a quick-plug connector, and the first fixing portion is also configured as a matching quick-plug interface. The connector 1 and the first fixing portion are respectively the male and female ends of the quick-plug connector. The connector 1 and the first fixing portion can be directly plugged in or unplugged to achieve quick disassembly.
[0023] Exemplarily, a protrusion may be further provided on the connector 1. Accordingly, the first fixing portion is a groove. The connector 1 is fixed by the engagement between the protrusion and the groove. When disassembling, the protrusion can be separated from the groove to achieve quick disassembly.
[0024] For example, the connector 1 may be an elastic member. For example, the connector 1 is provided with an elastic sheet, and accordingly, the first fixing portion is provided with an elastic buckle that matches the elastic sheet. The connector 1 is elastically connected to the elastic buckle, thereby enabling quick disassembly of the connector 1 and the first fixing portion. Optionally, the elastic sheet and the elastic buckle are made of metal.
[0025] Exemplarily, the connector 1 can also be a rod-shaped component with a socket. Accordingly, the first fixing portion is set as a protrusion that matches it. The connector 1 is fixedly connected to the protrusion through the socket. When disassembling, the socket can be pulled out from the protrusion to achieve quick disassembly.
[0026] Optionally, there are multiple connectors 1, multiple through holes are provided on the circuit board 2, and multiple first fixing parts are provided. The multiple connectors 1 pass through the multiple through holes one by one and are connected to the multiple first fixing parts one by one. It should be noted that at the multiple through holes, the hanging nails do not contact the cables inside the circuit board 2.
[0027] Optionally, the connecting member 1 is made of carbon steel or stainless steel.
[0028] A detachable connection is adopted between the connector 1 and the chassis 3 to fix the circuit board 2, eliminating the need for the installation of a lining plate, reducing the cost of the entire machine and enabling quick disassembly. The operation is simple and flexible, especially when a large number of circuit boards 2 need to be fixed to the chassis 3. Multiple circuit boards 2 can share a chassis 3 bottom shell, saving assembly costs.
[0029] Figure 3 This is a cross-sectional view of the connection structure between a connector and a circuit board proposed in an embodiment of the present application. Figure 2 In one possible embodiment, the connector 1 includes a soldering portion 5 and a connecting portion 4, wherein the soldering portion 5 is disposed within the through-hole and is soldered and fixed thereto; the connecting portion 4 is located outside the through-hole, with one end connected to the soldering portion 5 and the other end movably connected to the first fixing portion. The soldering portion 5 may include a head 6 and a rod 7, wherein the rod 7 is disposed within the through-hole, and one surface of the head 6 is in uniform contact with the circuit board 2, thereby ensuring a more stable connection between the soldering portion 5 and the circuit board 2. For example, the soldering portion 5 and the through-hole may be soldered and fixed using a reflow soldering process.
[0030] The edge of the connecting portion 4 may be provided with a flange 8. The flange 8 provided at the connecting portion 4 can be clamped in the first fixing hole when in use, so that the suspended circuit board 2 is more stable and not easy to fall off.
[0031] The first fixing portion can be a strip-shaped hole with an opening at one end. Such a strip-shaped hole with an opening is more convenient and quick to connect with the connecting portion 4 with the flange 8.
[0032] Exemplarily, the connector 1 can be a quick-connect connector, and the first fixing part is also a quick-connect connector that matches it. The connector 1 and the first fixing part are respectively the male and female heads of the quick-connect connector. The connector 1 and the first fixing part can be directly plugged in or unplugged to achieve quick disassembly. The connector 1 can also be provided with a protrusion. Accordingly, the first fixing part is a card slot. The connector 1 is fixed by the engagement of the protrusion and the card slot. When disassembling, the protrusion is separated from the card slot to achieve quick disassembly. The connector 1 can also be an elastic part. Exemplarily, the connector 1 is provided with an elastic sheet. Accordingly, the first fixing part is an elastic buckle. The connector 1 is elastically connected between the elastic sheet and the first fixing part to achieve quick disassembly of the connector 1 and the first fixing part. The elastic sheet and the elastic buckle can be made of metal material.
[0033] Figure 4 This is a cross-sectional view of a support structure of a support member and a CPU proposed in an embodiment of the present application. Figure 4 As shown, the circuit board 2 is also provided with a CPU bracket for supporting the CPU on the circuit board 2. The CPU bracket includes an upper CPU bracket 9 and a lower CPU bracket 12, which are located on either side of the circuit board 2. The CPU bracket is used to support the CPU on the circuit board 2. Using the CPU bracket as a support in its location can effectively improve the stability of the CPU and solve problems such as stress concentration near the CPU.
[0034] The support member 10 has at least one raised portion 11, which abuts against the CPU lower bracket 12. This contact between the raised portion 11 and the CPU lower bracket 12 improves the stability of the CPU. Furthermore, the raised portion 11 can also be used to support important components at their corresponding locations.
[0035] Since the back of the circuit board 2 is in a suspended or partially suspended state, for the important CPU, the raised portion 11 of the support member 10 is used as support at the suspended position, which can effectively solve the stability of the CPU on the circuit board 2 and solve the problems of stress concentration near the CPU.
[0036] Figure 5 This is a cross-sectional structural diagram of another connection relationship between a circuit board, a connector, and a support member proposed in an embodiment of the present application. Figure 5The support member 10 is detachably disposed within the chassis 3. Furthermore, the support member 10 can be fixed to the chassis 3 shell by screws, or connected by plugging, snapping, elastic connection, or other methods as described above. As long as the support member 10 and the chassis 3 can be fixed, no specific restrictions are imposed on the method of fixing the support member 10 to the chassis 3. The support member 10 has at least one raised portion 11 that abuts against the CPU lower bracket 12 on the circuit board 2 to support the CPU on the circuit board 2; the connector 1 passes through the circuit board 2 and is fixedly connected to the circuit board 2; the support member 10 is provided with a second fixing portion that matches the connector 1, and the connector 1 is detachably connected to the second fixing portion to fix the circuit board 2 to the support member 10.
[0037] In one possible embodiment, multiple second fixing portions may be included, wherein the second fixing portions are directly disposed on the chassis 3. The electronic device may also include multiple connectors 1, which may be connected to the multiple second fixing portions by plugging, snapping, or elastic connection. For example, the connector 1 may be a peg, an elastic member, a quick-connect connector, a rod-shaped component with a socket, etc., and the corresponding second fixing portion may be a through hole, an elastic snap, a quick-connect interface, a protrusion, or other structures.
[0038] A server is provided, comprising at least one electronic device as described above. In the server, a circuit board 2 can be quickly disassembled and assembled. Multiple circuit boards 2 can also share a single chassis 3, saving server installation space and costs.
