Description

Technical Field

[0001] The utility model belongs to the technical field of driving power supplies, and in particular relates to a driving power supply which is convenient for installing a cover body. Background Art

[0002] A driver power supply is a power converter whose main function is to convert the input power (such as AC power, DC power, etc.) into the voltage and current required by specific equipment to ensure that these devices can work stably and safely. This type of power supply is often used to drive loads with high precision or high energy efficiency requirements, such as LED lighting, motors, display screens, electronic control systems, etc.

[0003] As for LED driver power supply, it is specially designed to match the power supply requirements of LED lamps, and usually outputs a constant current source to adapt to the change of LED forward voltage drop and ensure the brightness and life of LED. LED driver power supply not only converts voltage and current, but also has built-in safety functions such as overcurrent protection, overvoltage protection, short circuit protection, etc. to ensure the reliability of power supply and the performance of LED.

[0004] Screw fixing usually requires a specific screwdriver or tool, which may become a limiting factor in some emergency maintenance situations. If there are no suitable tools on site, it will affect efficiency and emergency handling capabilities. Frequent disassembly and assembly may cause the screws to strip, break or lose, which not only affects the sealing of the cover, but may also pose a threat to the long-term stable operation of the equipment. Therefore, we hope to design a drive power supply with a new structure to solve this problem. Utility Model Content
