Description
Technical Field
[0001] The utility model relates to the technical field of power module power supplies, and more specifically to a moisture-proof isolation power module power supply. Background Art
[0002] A power module is a device that converts input power into a specific output power, which is used to provide the required power supply for electronic equipment. It is usually composed of multiple functional modules, which can be interconnected, exchanged and used in combination to meet the power supply requirements of different devices or systems. There are many types of power modules, including linear voltage regulated power modules, switching power modules, DC-DC converters, AC power modules, and isolated power modules. Their working principles are roughly the same, which is to convert and adjust the input voltage through a series of conversions and adjustments to output a stable voltage that meets the requirements of the equipment. These modules usually have functions such as voltage conversion, current regulation, overvoltage protection, and overcurrent protection, which can effectively manage and protect the power system.
[0003] The shortcomings of existing power modules:
[0004] First, during the assembly process of the existing power module power supply, long strips of seams will remain between the protective shells to facilitate future inspection and maintenance by the staff. However, such seams will leave space for the intrusion of air. There is moisture in the air and moisture is very easy to adhere to the surface of the equipment. Over time, the wires and solder joints will produce oxidation reactions after being exposed to moisture, resulting in unstable operation or even failure of the power module.
[0005] Second, the existing power module generates a large amount of heat. In order to reduce the temperature of the equipment, cold air is generally blown inward to achieve the purpose of cooling. However, when the air humidity is high, the humid air may form condensation water inside the power module during the cooling process, especially in the parts of the module with lower temperature. These condensation water may cause circuit short circuit. Utility Model Content

[0013] Furthermore, the limit block is made of rubber material, and the length of the sealing block is the same as the length of the inner surface of the first protective shell.
[0014] Technical effects and advantages of the utility model:
[0015] 1. According to the utility model, after the inspection is completed and the first protective shell and the second protective shell are installed, the knob is rotated to make the threaded rod start to rotate. After the threaded rod rotates, the first moving block moves on the threaded rod through the threaded hole. At this time, the driving rod moves along the direction of movement of the moving block. At this time, the driving rod begins to expand outward, which makes the sealing block contact with the inner surfaces of the first protective shell and the second protective shell. Through the setting of the auxiliary rod and the moving hole, the sealing block can remain in the same position during the movement and also provides stability for the movement of the sealing block. At this time, the limit block is connected with the first connecting groove and the second connecting groove, which can prevent the gap between the first protective shell and the second protective shell from being enlarged, which is beneficial to prevent water vapor from entering the power module, thereby extending the service life of the power module and protecting the stability and reliability of the entire system.
[0016] 2. In order to allow more moisture to enter the power module through the air vents, the utility model places activated carbon in the placement groove. The activated carbon can absorb and filter moisture in the air through its characteristics, and the air vents are directly opposite to the filter holes for rapid filtration. When the humidity in the power module is high, the monitor 304 starts to emit a signal to the alarm light to warn the staff, which can remind the staff to replace the activated carbon and check whether the equipment components are damaged. By preventing water vapor from entering, the occurrence of such faults can be reduced, thereby reducing maintenance costs and ensuring the performance, reliability and safety of the power module.
