Description

Technical Field

[0001] The present invention belongs to the field of electronic technology, and particularly relates to a copper bus protection structure and method. Background Art

[0002] Currently, while the performance of servers and PC products is getting higher and higher, the power consumption of servers and PCs is also increasing. Therefore, the motherboard needs to be able to withstand a greater power supply. The area and width of the power lines on the motherboard need to be larger and larger. However, due to the limited inner space of the motherboard and the fact that the power layer generally runs on the inner layer of the PCB board, many current designs adopt the method of running copper buses on the surface of the motherboard PCB to increase the area and width of the power lines.

[0003] However, this design method brings great risks. Since the power supply runs on the copper bus, the current passing through is very large. Compared with the inner layer of the PCB board, the copper bus is completely exposed directly to the air. Moreover, the server is powered on all year round, almost 365 * 24 hours. The copper bus is always in a working state, and the heat of the copper bus is relatively high. After long-term operation, it is easy for the anti-corrosion paint on the surface of the copper bus to be slowly corroded by heat, or there are other corrosive gases in the air, such as sulfur-containing gases, which will also corrode the copper bus. Currently, the corrosion resistance of copper buses is generally only tested with neutral salt spray (sodium chloride salt solution), and the tolerance time is generally about 48 hours, and the temperature generally does not exceed 35 °C, which is completely inconsistent with the actual working environment of the copper bus. The actual working environment of the copper bus is much harsher in terms of working time, working temperature, or the content of corrosive gases in the air.

[0004] When the copper bus is not corroded normally, the resistance value is relatively small, generally several mΩ. At 20 °C, the resistivity of copper is 0.0185 ohms / mm2 / m, that is, the resistance of a copper wire with a cross-sectional area of 1 square millimeter and a length of 1 meter is 0.0185 ohms. Generally, the copper buses used on servers are 20 to 30 centimeters long.

[0005] Once the copper bus is corroded, the resistance value will increase by many times, such as reaching 1000 times or a higher level. Coupled with the large current passing through the copper bus, generally 100A to several hundred A. According to the formula W = I2R, assuming the current is 100A and the resistance value is 5mΩ, the power before corrosion is 50W, and after corrosion, the power soars directly to 50000W. While the total power of a normal server's power supply is only about 1000W, this will directly cause the temperature of the copper bus to rise sharply. Since the PCB is generally below the copper bus, it will directly burn the PCB, and in severe cases, it will even cause a fire. Currently, there is no good solution to this problem.

[0006] There are many shapes of copper bars, such as straight-shaped and L-shaped. The basic shapes are relatively simple. In current copper bar designs, an insulating plastic is often added to the bottom of the copper bar to slightly lift the copper bar. There are some small components below the copper bar. When installing the copper bar, it may touch these small components, causing physical damage. Additionally, if the copper bar leaks copper due to corrosion or impact, it will lead to a short circuit.

[0007] In addition, since the copper bar needs to carry power signals, there is significant electromagnetic radiation relative to the high-speed signals on the main board. Therefore, it is necessary to avoid some high-speed signal areas. However, the copper bar is relatively long and not easy to avoid, so the problem of electromagnetic radiation still occurs.

Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0054] It should be noted that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. In the description of the present invention, "a plurality" or "several" means more than two, unless otherwise specifically defined.

[0055] Embodiment 1

[0056] The embodiment of the present invention provides a copper bar protection structure, as Figure 1As shown, the copper busbar protection structure includes a detection device 1, several columns 11, several crossbars 3, several bottom plates 4, and a bracket 6. The copper busbar 2 includes several horizontal copper busbars 2 and vertical copper busbars 2.

[0057] The several bottom plates 4 are arranged within the copper busbar 2 and are used to divide the copper busbar 2 into several horizontal copper busbars 2; the several columns 11 are arranged at the ports of the copper busbar 2 and are used to fix the copper busbar 2.

[0058] The several crossbars 3 are arranged at the lower sidewalls close to the corresponding bottom plates 4, and each horizontal copper busbar 2 is connected to the vertical copper busbar 2 through the corresponding crossbar 3.

[0059] The detection device 1 is arranged above the column 11 and is used to detect the current and resistance of the copper busbar 2; the bracket 6 is arranged at the bottom of the copper busbar 2 and is used to keep the copper busbar 2 away from the circuit board.

[0060] Wherein, the width value of the upper side of the bracket 6 is greater than that of the lower side.

[0061] Specifically, the copper busbar 2 is divided into multiple horizontal blocks from top to bottom. The specific number of horizontal blocks is related to the height of the copper busbar 2. Here, it is at least divided into 3 blocks. Since the height of the main board is not very high, it is generally recommended to be divided into 3 to 7 blocks. One column 11 is added to each end of the copper busbar 2 to fix each block of the copper busbar 2 on the column 11, and each horizontal copper busbar 2 is connected to the vertical copper busbar 2 on the column 11 through a crossbar 3.

[0062] At the same time, a bracket 6 with a wider upper side and a slender bottom is added at the bottom of the copper busbar 2 to lift the copper busbar 2 and prevent the bottom of the copper busbar 2 from directly contacting the circuit board PCB, which can solve the problems of heat dissipation of the copper busbar 2 or short - circuit burning of the PCB. And at the bottom of the slender part of the bracket 6, that is, close to the PCB, a temperature sensing wire 7 is buried in the middle, and the temperature sensing wire 7 can detect the temperature of the copper busbar 2.

[0063] Here, a multi-functional detection device 1 is added on top of the copper busbar 2. The detection device 1 is usually located on top of the copper busbar 2 and has several main functions. Function 1: The device has a battery inside and can be regularly charged from the copper busbar 2 to support the device's year-round operation. Function 2: The device can lift the crossbar 3 connecting the horizontal and vertical copper busbars 2, thereby disconnecting the individual horizontal copper busbars 2 and disconnecting the connection of the copper busbar 2 in case of abnormal temperature. Function 3: After lifting the crossbar 3, it can detect the resistance value of each horizontal copper busbar 2 and compare to see if it is qualified. Function 4: The device can slide down from the vertical slide rail 5 of the column 11 to cover the individual horizontal copper busbar 2. The device has a lamp inside that emits light (light that can be reflected back, such as ultraviolet and infrared light). The device shines the light on the copper busbar 2. The detection device 1 has a light receiver inside. Since the surface of the copper busbar 2 is smooth and painted, it has a fixed light reflectivity. In this way, the light receiver will receive the fixed reflected light. Once the copper busbar 2 rusts or oxidizes, the light cannot be reflected back or the reflection is insufficient, indicating that this area of the copper busbar 2 has oxidized or rusted.

[0064] In this embodiment, as Figure 2 shown, the crossbar 3 includes a rectangular structure and a hook-shaped structure. The rectangular structure includes a number of shafts 12 away from the hook-shaped structure. The hook-shaped structure includes a first notch A and a second notch B.

[0065] The rectangular structure abuts against the hook-shaped structure. The shaft 12 is used to connect the crossbar 3 to the copper busbar 2 close to the shaft 12.

[0066] The hook-shaped structure is used to connect the copper busbar 2 close to the hook-shaped structure. The first notch A is provided on the lower side of the hook-shaped structure, and the second notch B is provided on the upper side of the hook-shaped structure.

[0067] The copper busbar 2 further includes a number of copper busbar fixing nails. The copper busbar fixing nails are provided on the lower side close to the first notch A and are used to engage with the first notch A of the hook-shaped structure. The bottom plate 4 includes a number of bottom plate fixing nails, which are used to engage with the second notch B of the hook-shaped structure after the crossbar 3 rotates.

[0068] The number of copper busbar fixing nails and the number of bottom plate fixing nails are connected to the detection device 1.

[0069] Specifically, here the copper bar 2 is divided into three horizontal blocks. The number of horizontal blocks is not necessarily fixed, but they need to be evenly separated. One column 11 is added to each end of the copper bar 2. The column 11 includes two support feet 9 to fix each copper bar 2 on the column 11. Then each horizontal copper bar 2 is connected to the vertical copper bar 2 on the column 11 through a cross bar 3, as shown in Figure 2 The cross bar 3. There is a protruding hook-shaped structure on the left side of the cross bar 3 connected to the copper bar 2 on the left side. The hook-shaped structure includes a first notch A and a second notch B. In the middle of the right side of the rectangular structure of the cross bar 3 is a shaft 12. The shaft 12 is used to connect the cross bar 3 and the copper bar 2 on the right side. The cross bar 3 can also rotate along this shaft 12.

[0070] Normally, the first notch A is buckled on the fixing nail of the lower copper bar 2. The cross bar 3 can rotate. When the cross bar 3 is lifted, the second notch B is buckled with the fixing nail of the upper copper bar 2. In this way, the copper bars 2 on the left and right sides are disconnected at this time. In addition, both the copper bar fixing nail and the bottom plate 4 fixing nail can be connected to the detection device 1 through the inside of the column 11 for normal current detection and resistance value detection after the horizontal copper bar 2 is disconnected.

[0071] Lift the cross bar 3 connecting the horizontal and vertical copper bars 2, so as to disconnect the single horizontal block copper bar 2. The connection of the copper bar 2 can be disconnected when the temperature is abnormal. In addition, after lifting the connected cross bar 3, the resistance value of each horizontal copper bar 2 can be detected, and the detected resistance value of the horizontal copper bar 2 is compared with the normal resistance value to see if there is any problem.

[0072] In this embodiment, the copper bar protection structure further includes a slide rail 5. The inner side of the detection device 1 includes multiple regions, and each region includes several light-emitting lamps and a reflected light induction region.

[0073] The slide rail 5 is arranged between the detection device 1 and the bracket 6, on the single side close to the vertical copper bar 2.

[0074] The slide rail 5 is used for when performing reflection detection on the surface of the copper bar 2, the detection device 1 moves vertically along the slide rail 5 to perform reflection detection on the surface of each horizontal copper bar 2.

[0075] Specifically, the detection device 1 can slide up and down through the slide rail 5 to detect the copper bar 2 at different heights.

[0076] The inner side of the detection device 1 is divided into multiple regions, and each region includes multiple light-emitting lamps. Except for these lamps, other regions are reflected light induction regions.

[0077] When it is necessary to perform reflection detection on the copper bar 2, the detection device 1 moves along the slide rail 5 to cover a single horizontal copper bar 2 and emit light onto the copper bar 2. Since the surface of the copper bar 2 is smooth and painted, it has a fixed light reflectivity, so the reflection light sensing area will receive the fixed reflected light. When the copper bar 2 rusts or oxidizes, the light cannot be reflected back or the reflection is insufficient, indicating that the copper bar 2 in this area has oxidized or rusted.

[0078] In this embodiment, the column 11 further includes a plurality of support feet 9, and the support feet 9 are arranged at the bottom of the column 11; the vertical copper bar 2 includes pins 10, and the pins 10 are arranged at the bottom of the vertical copper bar 2, and the pins 10 are connected to the circuit board.

[0079] In this embodiment, the copper bar protection structure further includes a temperature sensing wire 7, and the temperature sensing wire 7 is arranged at the bottom of the lower side part of the bracket 6. The upper side wall of the temperature sensing wire 7 is connected to the copper bar 2 through a heat-conducting metal material 15 for detecting the temperature of the copper bar 2. One end of the temperature sensing wire 7 is connected to the circuit board; the detection device 1 includes a signal wire 8, and the signal wire 8 is arranged on one side of the slide rail 5, and one end of the signal wire 8 is connected to the circuit board.

[0080] Specifically, the signal wire 8 of the detection device 1 and the temperature sensing wire 7 are connected to the PCB together, thereby realizing the signal interconnection of the BMC chip, the temperature sensing wire 7 and the detection device 1.

[0081] In this embodiment, as Figure 3 shown, the bracket 6 includes a hollow cavity 17, and the hollow cavity 17 is filled with plastic, and a metal layer structure 16 is covered on the outer side of the bracket 6.

[0082] Specifically, the bracket 6 includes a hollow cavity 17. The wider part on the upper side of the bracket 6 is mainly filled with high-temperature resistant plastic, and the part from the middle of the bottom of the copper bar 2 to the temperature sensing wire 7 is made of a heat-conducting metal material 15, which can transfer the heat of the copper bar 2. At the same time, the outer side of the entire upper-wide and lower-thin bracket 6 is covered with a thin metal layer structure 16, which can play a shielding effect to prevent electromagnetic interference problems.

[0083] It is understandable that a bracket 6 with a wide upper side and a slender bottom is added to the bottom of the copper bar 2. The bracket 6 holds up the copper bar 2 to prevent the bottom of the copper bar 2 from directly contacting the PCB, solving the problems of heat dissipation of the copper bar 2 or short - circuit burning of the PCB. A temperature sensing wire 7 is buried on the lower side (close to the PCB) of the slender part at the bottom of the bracket 6. The temperature sensing wire 7 can detect the temperature of the copper bar 2. The hollow cavity 17 with a wide upper side of the bracket 6 is mainly filled with high - temperature resistant plastic. The part from the middle of the bottom of the copper bar 2 to the temperature sensing wire 7 is made of metal material to transfer the heat of the copper bar 2. The outer side of the whole bracket 6 with a wide upper side and a slender bottom is covered with a thin metal layer structure 16. The covering of the metal layer structure 16 can play a shielding role to prevent electromagnetic interference problems.

[0084] In addition, the copper bar protection structure is not fixed and can be adjusted and changed, as long as it can realize the functions of temperature measurement, resistance value detection of the copper bar 2, reflectance detection of the copper bar 2, and disconnection of the copper bar 2.

[0085] The beneficial effects brought by the technical solution disclosed in the embodiments of the present invention are:

[0086] The technical solution of the present invention can prevent the corrosion and short - circuit of the copper bar, ensure the normal function of the copper bar, and thus improve the customer satisfaction of the product.

[0087] The technical solution disclosed in the embodiments of the present invention can solve the problems of copper bar corrosion and short - circuit. Through a multi - functional detection device, the resistance value of the copper bar and the reflectance of the copper bar surface are periodically detected to ensure that the copper bar can be quickly detected after being corroded. In addition, according to the problems of the detected copper bar, by setting different temperature thresholds, when the temperature threshold is exceeded, various methods such as alarm, shutting down the server, or disconnecting the copper bar can be used to protect the copper bar, motherboard, server, or host. This ensures the normal function of the copper bar, thereby improving the quality of the server and the whole machine, and at the same time improving customer satisfaction.

[0088] Embodiment Two

[0089] The present invention provides a copper bar protection method, as Figure 4 shown. The copper bar protection method can be applied to a server. The method includes:

[0090] Step S1, detecting the copper bar through a detection device and protecting the copper bar according to the detection result; detecting the copper bar through a temperature sensing wire and protecting the copper bar according to the detection result.

[0091] Step S1 further includes:

[0092] Step S11, obtaining the current value of the copper bar through the detection device;

[0093] When the current value of the copper busbar is less than the first threshold, the resistance value of each horizontal copper busbar is detected according to the first period;

[0094] The resistance value of a single horizontal copper busbar is obtained through the detection device;

[0095] When the resistance value of the horizontal copper busbar is greater than the second threshold, an alarm prompt is sent to the baseboard management controller, and at the same time, feedback is given to the user; when the user does not handle the alarm prompt, the resistance value of each horizontal copper busbar is detected according to the second period, and the alarm prompt is continuously sent to the baseboard management controller;

[0096] The area where the single horizontal copper busbar does not reflect light or reflects insufficient light is obtained through the detection device;

[0097] When the area where the horizontal copper busbar does not reflect light or reflects insufficient light is greater than the third threshold, an alarm prompt is sent to the baseboard management controller; when the copper busbar is dusty, the dust is wiped off; when the user does not handle the alarm prompt, the reflection detection of each horizontal copper busbar is performed according to the third period;

[0098] When the resistance value of the horizontal copper busbar is greater than the second threshold and the area where the horizontal copper busbar does not reflect light or reflects insufficient light is greater than the third threshold, the resistance value and the reflection area of each horizontal copper busbar are detected according to the fourth period, and the alarm prompt is continuously sent to the baseboard management controller;

[0099] When the service life of the server is greater than the fourth threshold, the resistance value of each horizontal copper busbar is detected according to the fifth period, and the reflection area of each horizontal copper busbar is detected according to the sixth period.

[0100] Specifically, since the detection device is connected to the entire copper busbar, the current of the entire copper busbar can be detected. The entire copper busbar has a rated current value (i.e., the current value that can be tolerated during normal operation), and the copper busbar does not always operate at full load (dynamically adjusted according to the actual operation of the server). Therefore, when the copper busbar operates at less than 30% of the rated current, the crossbar of one of the horizontal copper busbars is lifted, the resistance value of the horizontal copper busbar is detected, and then this horizontal copper busbar is restored, and the resistance value detection work of all horizontal copper busbars is completed in turn. Since the detection requires disconnecting the corresponding crossbar, this detection does not need to be too frequent, and it can be performed about once every 5 - 7 days (the first period).

[0101] When the resistance value of a single horizontal copper bar exceeds 30% (for example, if the original resistance value of a single horizontal copper bar is 10 mΩ, exceeding 30% means exceeding 13 mΩ), an alarm will be sent to the BMC chip at this time, and then feedback to the user. It is necessary to stop the machine and open the cover for inspection. If the user does not handle this abnormality, the detection period will be halved, and it will be detected once every 3 days (the second cycle), and the alarm will continue.

[0102] Here, for the reflection detection of the copper bar, since it is not necessary to disconnect the horizontal copper bar, it can be detected once every 3 days (the second cycle). Once it is detected that there is no reflected light or the amount of reflected light is insufficient, the area of this type of copper bar will be recorded. If the area of this type of copper bar exceeds 10% of the total area of a single horizontal copper bar, an alarm will also be sent to the BMC chip, and it is necessary to stop the machine and open the cover for inspection; if there is a problem of dust on the copper bar, it can return to normal after wiping off the dust. If the user does not handle this abnormality, the reflection detection period of the copper bar will be changed to be detected once every 2 days (the third cycle).

[0103] If the resistance value of a single horizontal copper bar exceeds 30% and the area of the copper bar without reflected light exceeds 10% of the total area of the horizontal copper bar at the same time, the detection period will be changed to be detected once a day (the fourth cycle), and an alarm will continue to be sent to the BMC.

[0104] If the server has been used for more than 5 years and the PC product has been used for more than 3 years, the corresponding periods of all routine detections will be halved, and the detection periods after abnormalities will also be halved to ensure the safety of the copper bar during long-term use.

[0105] Among them, the first threshold is 30% of the rated current, the second threshold is 30% of the original resistance value of a single horizontal copper bar; the third threshold is 10% of the total area of a single horizontal copper bar, the fourth threshold is 5 years, the fifth cycle is once every 3 days; the sixth cycle is once every 1.5 days.

[0106] Step S12, obtain the temperature value of the copper bar through the temperature sensing wire;

[0107] When the temperature value of the copper bar is greater than the fifth threshold and the time when the temperature value of the copper bar is greater than the fifth threshold is greater than the sixth threshold, an alarm prompt will be sent to the baseboard management controller and the detection device; when the temperature value of the copper bar is greater than the seventh threshold and the time when the temperature value of the copper bar is greater than the seventh threshold is greater than the eighth threshold, the server will be shut down through the baseboard management controller, and at the same time, the copper bar will be disconnected through the detection device.

[0108] Specifically, when the temperature of the copper bar exceeds 100°C and the time for which the temperature exceeds 100°C is more than 10 seconds (the normal operating temperature of the copper bar is less than or equal to 100°C), a corresponding signal is sent to the BMC chip and the multifunctional detection device at the top of the copper bar for alarm. When the temperature of the copper bar exceeds 300°C and the time for which the temperature exceeds 300°C is more than 3 seconds (here, 300°C is close to the ignition temperature), the BMC is notified to directly shut down the server, and at the same time, feedback is given to the multifunctional detection device at the top of the copper bar to disconnect the copper bar, reducing the losses caused by fire.

[0109] Among them, the fifth threshold is 100°C, and the sixth threshold is 10 seconds; the seventh threshold is 300°C, and the eighth threshold is 3 seconds.
