Description

Technical Field

[0001] The utility model relates to the technical field of power supply equipment, and more specifically, it relates to a switch power supply housing. Background Art

[0002] A switch power supply is an electrical device of a modern control circuit, which can control the on-off time ratio of a switching tube and convert the standard voltage into a stable voltage or current required by the user through different forms of architectures. During use, the device needs to be protected by a housing.

[0003] Generally, most housings are composed of a housing body and a cover body. For common switch power supply housings, the assembly of the housing body and the cover body mostly works through multiple fixing screws to fix multiple points. However, during actual use, during the installation, debugging, and later maintenance of the device, it is often necessary to disassemble the housing body for maintenance. When disassembling the housing, it is necessary to remove all the multiple screws. The disassembly of the screws is relatively inconvenient, and it takes a lot of time to install and disassemble each screw. The operation is troublesome and the work efficiency is low. Moreover, most common housings are simple-structured housing bodies, which can only provide protection against impact, but do not have the ability to protect against external electromagnetic interference. When the switch power supply is working, if it is affected by external electromagnetic interference, it is easy to cause fluctuations in the power supply parameters and affect the working stability of the electrical device. In addition, in order to ensure the waterproof and rainproof ability of the limited housing body, the overall sealing performance of the housing body will become higher, resulting in a decrease in its heat dissipation performance, thereby affecting the service life of the switch power supply.
