Description

Technical Field

[0001] The utility model relates to the technical field of switching power supplies, and specifically relates to a switching power supply with a safety protection effect. Background Technique

[0002] A switching power supply is a high-frequency power conversion device, also known as a switching power supply or a switching converter, and is widely used in fields such as industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, and instrumentation.

[0003] When the existing switching power supply is in use, it is usually directly installed on the device or at the required position. Since the switching power supply is exposed externally, dust, pollutants, or rainwater are likely to enter the interior of the switching power supply, which may then lead to a decline in the performance of the switching power supply, malfunctions, or even damage.

[0004] In order to overcome the above defects, the prior art (Chinese patent with application number: 201920975531.0, application date: June 26, 2019) discloses a switching power supply with a protective shell. This switching power supply performs magnetic shielding on the switching power supply body through the steel magnetic shielding layer on the innermost side of the protective shell, shields the electric field generated by the switching power supply body through the copper electrostatic shielding layer in the middle layer of the protective shell, and utilizes the excellent heat conduction performance of copper to help the magnetic shielding layer dissipate heat quickly, thereby avoiding the situation where the switching power supply body cannot work properly due to excessive heat accumulation and high temperature inside the protective shell. The excellent insulation performance and heat conduction performance of the insulating heat-conducting plastic in the insulating layer are used to help the protective shell dissipate heat and avoid the occurrence of electric leakage and accidental electric shock.

[0005] Although the prior art can solve the protection of the switching power supply, since the switching power supply achieves the protection effect through the protective shell, the protective shell needs to be installed on the switching power supply with bolts. During the installation and disassembly process, tools such as screwdrivers or wrenches need to be used frequently. This not only increases the complexity of the operation, but also may cause the bolts to become loose or damaged due to improper operation, thereby affecting the stability of the protective shell, resulting in poor safety protection effect, and unable to quickly open the protective shell to repair or check the switching power supply, and at the same time unable to quickly install and disassemble the switching power supply.

[0006] Therefore, we have proposed a switching power supply with a safety protection effect, which can well solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1-7 , the present utility model provides the following technical solutions:

[0033] Embodiment 1: To solve the problem that when a switching power supply with a safety protection effect on the market is in use, although the switching power supply achieves the protection effect through a protective cover, the protective cover needs to be installed on the switching power supply with bolts, and tools such as screwdrivers or wrenches need to be frequently used during the installation and disassembly process. This not only increases the complexity of the operation but also may cause the bolts to loosen or be damaged due to improper operation, thereby affecting the stability of the protective cover and resulting in poor safety protection effect, and the protective cover cannot be quickly opened to repair or check the switching power supply. Reference can be made to Appendix Figure 1 -Appendix Figure 2 , Appendix Figure 4 and Appendix Figure 7 , including a switching power supply body 1, a protective shell 2, and a guide rail plate 3.
