Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a circuit board and a computing device. Background Art

[0002] At present, in computing devices such as servers based on Intel X86, for the installation of a processor (CPU), a corresponding base is usually set on the motherboard. The base can also be called a CPU socket. The CPU can be flexibly disassembled and assembled through the base structure. A supporting structure is set around the base on the motherboard. Since the CPU gold finger on the base is very fragile, when the motherboard is not installed with a CPU and a radiator, a cover plate is generally installed on the supporting structure, for example, the cover plate is buckled with the supporting structure to protect the gold finger of the CPU on the base.

[0003] However, in actual application scenarios such as transportation and storage of motherboards, the cover plate often falls off due to incomplete fastening between the cover plate and the support structure, which can easily damage and bend the CPU gold fingers on the base, resulting in the motherboard being scrapped. It can be seen that how to effectively prevent the cover plate from falling off and avoid damage to the base has become a technical problem that needs to be solved urgently. Utility Model Content

[0004] The embodiments of the present application provide a circuit board and a computing device, which can effectively detect the installation status of the cover plate, prevent the cover plate of the base from falling off, and avoid damage to the base.

[0005] In a first aspect, an embodiment of the present application provides a circuit board, the circuit board includes a base, a support structure, a power supply, an alarm module, a switch module and a cover plate, wherein:

[0006] The supporting structure is arranged around the base; the switch module is arranged on the supporting structure.

[0007] The first end of the alarm module is electrically connected to the first end of the power supply, the second end of the alarm module is electrically connected to the first end of the switch module, and the second end of the switch module is electrically connected to the second end of the power supply.

[0008] The switch module is used to control the alarm module to be connected to the power supply when the cover plate is not attached to the support structure, and to control the alarm module to be disconnected from the power supply when the cover plate is attached to the support structure.

[0009] The alarm module is used to output a first alarm signal when the alarm module is connected to the power supply, and the first alarm signal is used to indicate that the cover plate is not in contact with the support structure. It can be seen that the circuit board provided in the embodiment of the present application can effectively detect the installation status of the cover plate, and when the cover plate is not installed in place, a corresponding alarm signal is issued in time, thereby effectively preventing the cover plate of the base from falling off, avoiding damage to the base, and reducing the number of damaged circuit boards.

[0010] Optionally, the support structure includes at least two frames, wherein:

[0011] At least one switch module is disposed on each frame. In the embodiment of the present application, by disposing the switch module on the frame of the supporting structure, the switch module can effectively detect the installation state of the cover plate.

[0012] Optionally, the frame includes a connector, wherein:

[0013] The distance between the switch module and the connecting member on the frame is less than or equal to a preset first distance threshold.

[0014] The connector is used to make the cover plate fit with the support structure. In the embodiment of the present application, by placing the switch module on the frame close to the connector, the installation state of the cover plate can be accurately detected when the connector on the frame is connected to the cover plate.

[0015] Optionally, the frame is provided with through holes, wherein:

[0016] The switch module is arranged in the through hole, and the upper surface of the switch module is higher than the upper edge of the through hole. In the embodiment of the present application, by arranging a through hole on the frame, arranging the switch module in the through hole, and the upper surface of the switch module is higher than the upper edge of the through hole, the installation state of the cover plate can be accurately detected when the frame is connected to the cover plate.

[0017] Optionally, the circuit board further includes a heat dissipation device, wherein:

[0018] The switch module is also used to control the alarm module to connect to the power supply when the heat dissipation device is not attached to the support structure, and to control the alarm module to disconnect from the power supply when the heat dissipation device is attached to the support structure.

[0019] The alarm module is also used to output a second alarm signal when the alarm module is connected to the power supply, and the second alarm signal is used to indicate that the heat sink is not in contact with the support structure. It can be seen that in the embodiment of the present application, the circuit board can also perform installation detection on the heat sink of the CPU after installing the CPU, which can effectively detect the installation status of the heat sink, and when the heat sink is not installed in place, a corresponding alarm signal is issued in time, thereby effectively guiding the correct installation of the heat sink to ensure sufficient heat dissipation of the CPU.

[0032] In order to better understand the technical solutions provided by the embodiments of the present application, the relevant embodiments of the present application are described below.

[0033] The circuit board includes a CPU base and a supporting structure. The CPU base can also be called a CPU socket, and the CPU base includes gold fingers for installing the CPU.

[0034] Since the CPU gold fingers on the base are very fragile, a cover plate is generally installed on the support structure when the CPU and the heat sink are not installed on the motherboard. For example, the cover plate can be buckled with the support structure, specifically by pressing and buckling the holes at the four corners of the cover plate with the support structure on the motherboard to protect the gold fingers of the CPU on the base.

[0035] However, in actual application scenarios such as transportation and storage of motherboards, it is found that when the cover installer presses hard to fasten the cover and the support structure, there is no intuitive feedback to the installer whether the cover is installed in place. As a result, whether the cover is installed in place depends entirely on whether the installer presses accurately, which can easily cause the cover to be merely placed on the support structure and not fastened to the support structure. In the case that the cover and the support structure are not fastened tightly, the motherboard will cause irreversible damage to the CPU gold finger during transportation or handling. Typical damage is that the CPU gold finger is damaged and bent, and the motherboard needs to be returned to the factory for repair, or even cannot be repaired, resulting in the motherboard being scrapped.

[0036] It can be seen that the current motherboard design can easily cause the CPU gold fingers on the base to be damaged and bent, or even the motherboard to be scrapped.

[0037] In response to the above problems, an embodiment of the present application provides a circuit board and a computing device, which can effectively prevent the cover of the CPU base from falling off and avoid damage to the base.

[0038] See also Figure 1 , is a schematic diagram of the structure of a circuit board provided in an embodiment of the present application. The circuit board 11 includes a base 101, a support structure 102, a power supply 103, an alarm module 104, a switch module 105 and a cover 106, wherein:

[0039] The support structure 102 is disposed around the base 101 . The switch module 105 is disposed on the support structure 102 .

[0040] In one embodiment, the support structure 102 may be annular with a gap, and the base 101 is located in an inner area of ​​the annular pattern formed by the support structure 102 .

[0041] In one embodiment, the switch module 105 may be disposed on the upper surface of the support structure 102 .

[0042] In one embodiment, the number of the switch module 105 may be one or more. Figure 1 Take two switch modules 105 as an example.

[0043] A first end of the alarm module 104 is electrically connected to a first end of the power supply 103 , and a second end of the alarm module 104 is electrically connected to a first end of the switch module 105 . A second end of the switch module 105 is electrically connected to a second end of the power supply 103 .

[0044] In one embodiment, the power supply 103 may be a battery module on the circuit board 11, such as a button battery. The battery module may be electrically connected to the power conversion module on the circuit board 11, and when the circuit board 11 is not powered on, the battery module supplies power to the alarm module 104. When the circuit board 11 is powered on, the power supply (e.g., 5V or 3.3V) output by the power conversion module supplies power to the alarm module 104. The first end of the power supply 103 may be a positive end, and the second end of the power supply 103 may be a negative end.

[0045] The switch module 105 is used to control the alarm module 104 to be connected to the power supply 103 when the cover plate 106 is not in contact with the support structure 102 .

[0046] The switch module 105 is also used to control the alarm module 104 to be disconnected from the power supply 103 when the cover plate 106 is attached to the support structure 102 .

[0047] The switch module 105 is used to control the connection or disconnection between the alarm module 104 and the power supply 103 .

[0048] In one embodiment, when the cover plate 106 is not attached to the support structure 102 (that is, the cover plate 106 is not installed in place), the switch module 105 controls the alarm module 104 to be connected to the power supply 103, so that the alarm module 104 can output the first alarm signal. When the cover plate 106 is attached to the support structure 102 (that is, the cover plate 106 is installed in place), the switch module 105 controls the alarm module 104 to be disconnected from the power supply 103, so that the alarm module 104 does not output the first alarm signal.

[0049] The alarm module 104 is used to output a first alarm signal when the alarm module 104 is connected to the power supply 103 , and the first alarm signal is used to indicate that the cover plate 106 and the support structure 102 are not in contact with each other.

[0050] The alarm module 104 is further configured to not output the first alarm signal when the alarm module 104 is disconnected from the power supply 103 .

[0051] In one embodiment, when the alarm module 104 is connected to the power supply 103, it outputs a first alarm signal to indicate that the cover plate 106 is not attached to the support structure 102, so that the personnel can be notified to attach the cover plate 106 to the support structure 102 in time. When the alarm module 104 is disconnected from the power supply 103, since there is no power supply, the first alarm signal will not be output, which means that the cover plate 106 is attached to the support structure 102 (that is, the cover plate 106 is installed in place).

[0052] In one embodiment, the base 101 includes a processor CPU socket, and the CPU socket can be used to install a CPU.

[0053] In one embodiment, the circuit board 11 includes a mainboard of a computing device such as a server.

[0054] In the embodiment of the present application, by setting a switch module and an alarm module on the circuit board, when the cover plate of the base is not installed in place, the switch module automatically controls the alarm module to connect to the power supply, so that the alarm module outputs a corresponding alarm signal, and can timely and effectively notify relevant personnel to reinstall the cover plate so that the cover plate fits the supporting structure of the circuit board, and when the cover plate of the base is installed in place, the switch module automatically controls the alarm module to disconnect from the power supply, so that the alarm module does not output a corresponding alarm signal. It can be seen that the circuit board provided in the embodiment of the present application can effectively detect the installation status of the cover plate, and when the cover plate is not installed in place, timely send out a corresponding alarm signal, thereby effectively preventing the cover plate of the base from falling off, avoiding damage to the base, and reducing the number of damaged circuit boards.

[0055] In one embodiment, see Figure 2 , the support structure 102 includes at least two frames 1021, wherein:

[0056] At least one switch module 105 is disposed on each frame 1021 .

[0057] Specifically, the switch module 105 can be arranged on the upper surface of the frame 1021, and the frame 1021 can be used to carry the cover plate 106. When installing the cover plate 106, the installer presses the cover plate 106 to make the cover plate 106 fit with the frame 1021, and the pressure on the switch module 105 can change the switch state of the switch module 105 to the first state. The switch module 105 can disconnect the alarm module 104 from the power supply 103 in the first state.

[0058] In addition, if the installer uses an incorrect installation method or uses less force, resulting in the cover plate 106 not fitting with the frame 1021, the switch module 105 is in the second state because the pressure on the switch module 105 is small. The switch module 105 can connect the alarm module 104 to the power supply 103 in the second state.

[0059] In the embodiment of the present application, by arranging the switch module on the frame of the supporting structure, the switch module can effectively detect the installation status of the cover plate.

[0060] In one embodiment, see Figure 2 , the frame 1021 includes a connecting piece 1022, wherein:

[0061] The distance between the switch module 105 and the connecting member 1022 on the frame 1021 is less than or equal to a preset first distance threshold.

[0062] The connecting member 1022 is used to make the cover plate 106 fit closely with the supporting structure 102 .

[0063] Specifically, the connector 1022 of the frame 1021 can be used to connect the cover plate 106, so that the cover plate 106 fits the support structure 102. In addition, the switch module 105 can be positioned on the frame 1021 close to the connector 1022, for example, the distance between the switch module 105 and the connector 1022 on the frame 1021 is less than or equal to a preset first distance threshold, so as to ensure that the switch module 105 can accurately detect the installation state of the cover plate.

[0064] In one embodiment, the connector 1022 may be a snap-fit ​​assembly, which is used to snap the cover plate 106 and the support structure 102 together.

[0065] In the embodiment of the present application, by placing the switch module on the frame close to the connecting piece, the installation state of the cover plate can be accurately detected when the connecting piece on the frame is connected to the cover plate.

[0066] In one embodiment, see Figure 3 , the frame 1021 is provided with a through hole 1023, wherein:

[0067] The switch module 105 is disposed in the through hole 1023 , and the upper surface of the switch module 105 is higher than the upper edge of the through hole 1023 .

[0068] Specifically, the number of through holes 1023 on each frame 1021 can be set according to the number of switch modules 105 on the frame 1021. For example, if one switch module 105 is set on each frame 1021, then one through hole 1023 is correspondingly set on each frame 1021.

[0069] The switch module 105 is disposed in the through hole 1023. In order to detect the installation state of the cover plate, the upper surface of the switch module 105 can be higher than the upper edge of the through hole 1023, so that pressure can be applied to the switch module 105 when the cover plate 106 is installed.

[0070] In the embodiment of the present application, a through hole is provided on the frame, a switch module is provided in the through hole, and the upper surface of the switch module is higher than the upper edge of the through hole, so that the installation status of the cover plate can be accurately detected when the frame is connected to the cover plate.

[0071] In one embodiment, the switch module 105 and the alarm module 104 and the power supply 103 may be electrically connected by wires (i.e., flying wires) or by printed circuit board (PCB) wiring, which is not limited in the embodiment of the present application.

[0072] In one embodiment, when the switch module 105 is disposed in the through hole 1023, a printed circuit board (PCB) wiring is used to electrically connect the switch module 105 with the alarm module 104 and the power supply 103. When the switch module 105 is disposed on the upper surface of the frame 1021, a wire is used to electrically connect the switch module 105 with the alarm module 104 and the power supply 103.

[0073] In one embodiment, the distance between the alarm module 104 and the base 101 on the circuit board 11 is less than or equal to a preset second distance threshold.

[0074] Specifically, in order to distinguish the alarm module 104 from other indication modules (such as indicator lights) that may be configured on the circuit board, the alarm module 104 can be as close as possible to the base 101. For example, the distance between the alarm module 104 and the base 101 on the circuit board 11 is less than or equal to the preset second distance threshold.

[0075] In the embodiment of the present application, by placing the alarm module on the circuit board close to the base, the alarm signal output by the alarm module can intuitively and accurately indicate the installation status of the cover.

[0076] In one embodiment, the switch module 105 includes a micro normally closed push button switch. The micro normally closed push button switch can reduce the space occupied by the switch module on the circuit board as much as possible, which is conducive to the miniaturization design of the circuit board.

[0077] In one embodiment, the alarm module 104 includes one or both of a sound signal output device and a light signal output device.

[0078] Specifically, the sound signal output device may include a buzzer. The light signal output device may include an indicator light (e.g., an LED light). When the alarm module 104 is connected to the power supply 103, if the alarm module 104 is a sound signal output device, the alarm signal (e.g., the first alarm signal) output by the alarm module 104 is a sound signal (e.g., the sound emitted by a buzzer). If the alarm module 104 is a light signal output device, the alarm signal (e.g., the first alarm signal) output by the alarm module 104 is a light signal (e.g., the light emitted by an LED light).

[0079] In addition, if the alarm module 104 includes both a sound signal output device and a light signal output device, the alarm signal (such as the first alarm signal) output by the alarm module 104 includes both a sound signal (such as the sound emitted by a buzzer) and a light signal (such as the light emitted by an LED lamp). The simultaneous issuance of alarm signals by sound and light signals can more accurately indicate the circuit board on which the cover is not installed. For example, when the number of circuit boards in a batch is large, the sound and light signals can be used to quickly and accurately locate the corresponding circuit board, thereby timely adjusting the installation status of the cover on the circuit board so that the cover fits the support structure.

[0080] In one embodiment, see Figure 4 , is a schematic diagram of a circuit structure for detecting cover plate installation provided in an embodiment of the present application.

[0081] Specifically, when the cover plate 106 is not in contact with the support structure 102, the switch of the switch module 105 is connected to point B. At this time, corresponding to the second state described above, the alarm module 104 is connected to the power supply 103, and the alarm module 104 outputs a first alarm signal. After receiving the alarm signal, the relevant personnel can adjust the installation state of the cover plate 106, for example, by pressing the cover plate 106 hard, so that the cover plate 106 is in contact with the support structure 102. The installation effect can be as follows: Figure 5 At this time, the switch of the switch module 105 is connected to point A, which corresponds to the aforementioned first state, the alarm module 104 is disconnected from the power supply 103, and the alarm module 104 does not output an alarm signal.

[0082] It can be seen that the circuit for detecting the installation of the cover provided in the embodiment of the present application can effectively detect the installation status of the cover and promptly issue an alarm signal when the cover is not installed properly, thereby effectively preventing the cover of the base from falling off, avoiding damage to the base, and reducing the number of damaged circuit boards.

[0083] In one embodiment, after the cover 106 is removed and the CPU is installed on the base 101, it is usually necessary to install a heat sink for the CPU on the support structure 102. At this time, the circuit board can detect the installation status of the heat sink in the same way.

[0084] Specifically, the switch module 105 is also used to control the alarm module 104 to connect with the power supply 103 when the heat dissipation device is not attached to the support structure 102. When the heat dissipation device is attached to the support structure 102, the alarm module 104 is controlled to disconnect with the power supply 103.

[0085] The alarm module 104 is also used to output a second alarm signal when the alarm module 104 is connected to the power supply 103, and the second alarm signal is used to indicate that the heat dissipation device is not attached to the support structure 102. When the alarm module 104 is disconnected from the power supply 103, the second alarm signal is not output.

[0086] It can be seen that in the embodiment of the present application, the circuit board can also perform installation detection on the heat sink of the CPU after the CPU is installed, so as to effectively detect the installation status of the heat sink and promptly issue a corresponding alarm signal when the heat sink is not installed properly, thereby effectively guiding the correct installation of the heat sink to ensure sufficient heat dissipation of the CPU.

[0088] Among them, the computing device may include a server.
