Description

Technical Field

[0001] This utility model relates to the field of switching power supplies, and in particular to a switching power supply with low standby power consumption. Background Technology

[0002] A switch-mode power supply (SMPS), also known as a switching power supply or switching converter, is a high-frequency power conversion device and a type of power supply. Its function is to convert a voltage at a certain level into the voltage or current required by the user through different structural forms. The input of a switching power supply is mostly AC power (such as mains power) or DC power, while the output is mostly devices that require DC power, such as personal computers. The switching power supply performs the voltage and current conversion between these two sources.

[0003] Existing switching power supplies inevitably experience internal component damage after prolonged use. This requires users to open the power supply casing for repair. However, the complex installation structure of some switching power supply casings makes it difficult for users to quickly open them for repair, thus affecting their work efficiency. Therefore, we propose a low standby power consumption switching power supply to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a low standby power consumption switching power supply to solve the problems mentioned in the background art.

[0007] Preferably, each of the two No. 1 blocks has a groove on one side that matches the No. 2 block, and the outer sides of the two No. 2 blocks are slidably connected to the inner side of the corresponding groove. Each of the two No. 2 rollers has a No. 4 block fixedly connected to one side, and each of the two protective shells has an elongated hole on one side that matches the No. 4 block. The outer sides of the two No. 4 blocks are slidably connected to the inner side of the corresponding elongated hole.

[0008] Preferably, each of the two protective shells has a handwheel on its outer side, a screw is fixedly connected to the inner side of each of the two handwheels, and the outer side of each of the two screws is threadedly connected to the inner side of the corresponding No. 4 block. Each of the two protective shells has a No. 5 block fixedly connected to its top, and a fixing post is threadedly connected to the inner side of each of the two No. 5 blocks. Each of the two handwheels has multiple insertion holes adapted to the fixing posts on its top, and the outer side of each of the two fixing posts is movably inserted into the inner side of the corresponding insertion holes.

[0009] Preferably, a filter screen is threadedly connected to the top of the switching power supply body via a fastening bolt.

[0010] Preferably, a display screen is fixedly connected to one side of the switching power supply body, and multiple wire harness blocks are fixedly connected to the inner wall of one side of the switching power supply body.

[0011] Preferably, each of the two protective shells is fixedly connected to a connecting frame on one side, and the inner sides of the two connecting frames are rotatably connected to the outer sides of the corresponding screws.

[0012] In this utility model, a low standby power consumption switching power supply is provided by closely arranging the first and second components inside the switching power supply body and using wire harnesses to constrain the internal circuit distribution of the device. This optimizes the internal circuit layout of the device, thereby reducing standby power consumption. When the user needs to open the device to repair the internal components.

[0013] In this utility model, a low standby power consumption switching power supply is described. By loosening the fixing post and turning the handwheel, the screw starts to rotate. Then, block number four begins to move vertically. As block number four moves, roller number two starts to drive connecting rod number two to rotate. Subsequently, connecting rod number one also starts to rotate, causing block number two to also start to move vertically. This causes block number one to disengage from the slot. At this point, the user can directly remove the outer casing and begin component repair work.

[0014] This utility model has a reasonable structural design. Through the cooperation between the handwheel, screw, block number one and connecting rod number two, the outer shell can be easily fixed together with the device, so that the user can quickly disassemble the outer shell when the device needs to be opened, which further improves the user's work efficiency.
