Abstract
Description
Technical Field
[0001] The present application relates to the field of computer technology, for example, to a reinforced protection device. Background Art
[0002] In the current domestic reinforced server market, the power supply part of the server is usually equipped with protection devices, such as onboard fuses and onboard TVS, to ensure the stable operation of the equipment in various harsh environments.
[0003] However, since the equipment needs to undergo a series of rigorous tests and the stability of the mains power cannot be guaranteed, these protection devices are often damaged. Whether at the test site or the inspection site, once these protection devices are damaged, due to their on-board characteristics, non-professionals cannot replace them on site in time, and professional hardware engineers are required to use professional tools to operate. This not only affects the progress of the project, but may also cause the project to be delayed. What's more serious is that when the protection device of the equipment is damaged due to some unavoidable factors during actual operation, it may be necessary to return the equipment to the factory for repair, which undoubtedly increases the cost and time of maintenance.
[0004] Another problem is that when the protection device is damaged and the protection is activated, the staff cannot judge whether it has worked only through visual inspection or background monitoring. In order to determine the fault point, professionals are often required to disassemble the equipment for inspection, and they need to disassemble it to the board level to make an accurate judgment.
[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0034] The present disclosure aims to provide a reinforced equipment protection device, which can not only provide necessary protection when the equipment has overcurrent or overvoltage, but also meet strict environmental adaptability indicators such as vibration, impact, transportation drop and vibration. In addition, the device is designed to be easy to maintain and detect, ensuring that when the protection device is effective or damaged, the problem can be quickly discovered and solved, thereby greatly improving the reliability of the equipment and reducing maintenance costs.
[0035] Specifically, Figure 1 As shown, as an example, the present disclosure mainly consists of a first protective member 1, a second protective member 2, a first anti-falling screw 3, a second anti-falling screw 4, a first protective member reinforcement structure 5, a second protective member reinforcement structure 6, a first inspection point 7, a second inspection point 8, and a circuit board fixing structure 9:
[0036] Protection mechanism: The first protection component 1 and the second protection component 2 together constitute a two-level protection mechanism for the device. When the device encounters overcurrent or overvoltage, these protection components will exert their physical properties to provide protection for the entire device.
[0037] Reinforcement and stability: The first protection member 1 and the second protection member 2 are fastened to the circuit board fixing structure 9 by the first anti-drop screw 3 and the second anti-drop screw 4. This design not only ensures the stability of the protection device, but also meets the environmental adaptability indicators such as vibration and impact.
[0038] Easy-to-maintain design: When the first protective member 1 or the second protective member 2 is damaged, the damaged protective member can be easily replaced by simply removing the corresponding anti-drop screws. This design greatly simplifies the maintenance process and reduces maintenance costs.
[0039] Detectability design: The first checkpoint 7 and the second checkpoint 8 are designed as comprehensive current and voltage detection points. Through these detection points, the working status of the protection device can be monitored in real time. When abnormal data appears, the background system can quickly identify and issue an alarm, so as to discover and solve the problem in time.
[0040] As an example, the damage of the protection device can be determined by the current and voltage values of the current and voltage comprehensive detection points. The following steps can be followed:
[0041] 1. Set the reference value: For voltage and current, first of all, it is necessary to clarify the voltage and current range of the circuit where the protection device is located under normal working conditions. For example, in the case of a lithium battery protection board, the normal output voltage is usually between 2.5V and 4.3V, and the output current should be below 5A.
[0042] 2. Actual measurement: Use appropriate measuring tools (such as a multimeter) to measure the voltage and current in the circuit at the current and voltage integrated detection point. Make sure that the range and accuracy of the measuring tool are suitable for the circuit to be tested.
[0043] 3. Data comparison: Compare the actual measured voltage and current values with the reference values set in step 1. If the measured values are outside the normal range, this may indicate that the protection device is damaged or its performance has degraded.
[0044] 4. Troubleshooting: If abnormal voltage or current is found, first check whether the connection is good and eliminate external factors such as poor contact or open circuit.
[0045] 5. If the external connection is normal, it may be necessary to further check the protection device itself, such as checking for obvious physical damage or signs of burning.
[0046] 6. Professional testing: If the initial inspection fails to identify the problem, more professional testing may be required, such as using advanced equipment such as an oscilloscope to perform waveform analysis on the circuit, or sending the protection device to a professional organization for detailed fault diagnosis.
[0047] 7. Replacement verification: If you suspect that the protection device is damaged, you can try to replace the original device with a new, known good protection device, and then measure the voltage and current values again to verify whether the problem is with the protection device.
[0048] 8. Record and Analysis: Record all measurement data and troubleshooting process to facilitate subsequent analysis and experience summary. If the protection device is indeed damaged, the cause of the damage should be analyzed to avoid similar situations from happening again.
[0049] As another example, when the equipment is powered off, to determine the damage of the protection device by measuring the electrical values of the reserved monitoring points, you can follow the steps below:
[0050] Prepare tools: First, prepare the required measuring tools, such as a multimeter. Make sure the multimeter has sufficient battery power or is connected to a stable external power source.
[0051] 1. Select the appropriate measurement range, usually voltage or resistance, depending on the type of reserved monitoring points and expected measurement values.
[0052] 2. Safety measures: Before taking any measurements, ensure that the equipment is completely powered off and take necessary safety measures, such as wearing insulating gloves and using insulating pads.
[0053] 3. Check and confirm that all power-related connections have been disconnected to avoid accidental electric shock.
[0054] 4. Measure electrical values: Connect the test leads of the multimeter to the two ends of the reserved monitoring points. If you are measuring voltage, make sure the multimeter is set to the voltage measurement position; if you are measuring resistance, make sure the power supply is completely disconnected and set the multimeter to the resistance measurement position.
[0055] 5. Record the measured electrical values, such as voltage or resistance.
[0056] 6. Determine the status of the protection device: Compare the measured electrical value with the specification parameters of the protection device. For example, for a fuse or circuit breaker, you can measure the resistance value at both ends. If the resistance value is close to zero, it may indicate that the protection device is damaged (short circuit); if the resistance value is infinite, it may indicate that the protection device is disconnected (open circuit).
[0057] 7. For other types of protection devices, such as thermal relays, overload relays, etc., it is necessary to judge based on their working principles and characteristics. For example, a thermal relay usually has a temperature-sensitive element that automatically disconnects the circuit when the temperature exceeds the set value. Therefore, its working status can be judged by measuring the resistance value of its temperature-sensitive element.
[0058] 8. Further diagnosis: If the preliminary measurement results show that the protection device may be damaged, further diagnosis can be performed. For example, use an oscilloscope to observe the waveform changes in the circuit, or use a current clamp to measure the current value in the circuit.
[0059] 9. Based on further diagnostic results, confirm the damage of the protection device and formulate a corresponding repair or replacement plan.
[0060] The present invention realizes stable operation, easy maintenance and rapid fault detection of equipment in harsh environments through innovative structural design and detectability design, which not only improves the reliability of the equipment, but also greatly reduces the subsequent maintenance cost and time cost.
[0061] In addition, it has the following advantages:
[0062] 1. Meet environmental adaptability and reinforcement indicators: This disclosure uses anti-drop screws for fastening to ensure the stability of the protection device in harsh environments. The protection device itself is designed to meet the reinforcement indicators and can withstand various mechanical stresses.
[0063] 2. Easy to maintain: Use conventional screws for fastening, which is convenient for on-site maintenance.
[0064] When the protective device is damaged, it can be quickly replaced with simple tools without the need for professional personnel.
[0065] 3. Detectability: Design comprehensive current and voltage detection points to monitor the working status of protection devices in real time. In addition, when the equipment is powered off, the damage of the protection device can be determined by measuring the electrical values of the reserved monitoring points.
[0066] 4. The working status of the protection device can be identified through the background system without disassembling the structural parts.
