Abstract
Description
Technical Field
[0001] This utility model relates to the field of switching power supply technology, specifically a switching power supply with an insulating structure. Background Technology
[0002] Switching power supplies, also known as switching power supplies or switching converters, are high-frequency power conversion devices. Their function is to convert a voltage at a certain level into the voltage or current required by the user through different architectures. Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment and other fields. At present, the connection between the plug and the power supply is mostly direct connection, which is easy to be dislodged by external force during use.
[0003] Existing switching power supplies use direct connection during use, which can easily lead to leakage. The insulation protection measures on the switching power supply are inadequate, and the insulation protection is not effective when the power switch is started.
[0004] Therefore, those skilled in the art have provided a switching power supply with an insulating structure to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide a switching power supply with an insulating structure to solve the problems mentioned in the background art, such as the ease with which leakage occurs, poor insulation protection measures in switching power supplies, ineffective insulation protection during power switch startup, and poor insulation effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A switching power supply with an insulating structure includes: a switching power supply, an insulating frame mounted on the bottom of the switching power supply, a switch lever mounted on the front surface of the switching power supply, an insulating rubber pad frame provided on the outer side of the switch lever, a knob movably mounted on one side of the switch lever, and a lever connected to one side of the knob's surface, a ceramic core installed inside the knob, and a ceramic rod integrally connected to the surface of the ceramic core, and an oil-impregnated layer provided inside the switch lever, with a metal rod installed inside the oil-impregnated layer.
[0008] As a further improvement in this invention, the inner wall of the insulating frame is provided with an insulating pad for insulation.
[0009] As a further improvement in this invention, the knob is rotatably connected to the switching power supply, and the knob is fixed to the ceramic core by screws.
[0010] As a further improvement in this invention, the external structural dimensions of the ceramic rod match the internal structural dimensions of the cantilever rod, and the ceramic rod is fixedly inserted into the interior of the cantilever rod.
[0011] As a further improvement in this invention, a heat dissipation hole is provided on the left side of the knob for heat dissipation.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The knob is located on one side of the switch lever. A lever is connected to the surface of the knob. By rotating the knob, the lever can lift the switch lever, thereby turning on the power switch. This avoids the operator's hands from directly contacting the power switch, preventing leakage and providing insulation.
[0014] 2. A ceramic core is installed inside the knob. The ceramic core is connected to the ceramic rod, and the ceramic rod is connected to the lever. The ceramic is used to achieve insulation, thereby increasing the insulation effect of the knob and preventing leakage when using the knob.
[0015] 3. An oil-immersed layer is installed inside the switch lever. The insulation of the oil-immersed layer can increase the insulation of the switch lever and prevent electric shock accidents caused by accidental contact with the switch lever. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 This utility model embodiment provides a switching power supply with an insulating structure, including: a switching power supply 1, an insulating frame 2 installed at the bottom of the switching power supply 1, and an insulating pad 8 for insulation provided on the inner wall of the insulating frame 2.
[0023] Specifically, an insulating frame 2 is provided on the outside of the switching power supply 1 to protect the switching power supply 1. An insulating pad 8 is provided on the inner wall of the insulating frame 2. The insulating pad 8 is made of rubber material and can achieve the insulation effect.
[0024] A switch lever 3 is mounted on the front surface of the switching power supply 1. An insulating rubber pad frame 4 is provided on the outside of the switch lever 3. A knob 5 is movably mounted on one side of the switch lever 3, and a lever 6 is connected to one side of the knob 5. A ceramic core 9 is installed inside the knob 5, and a ceramic rod 10 is integrally connected to the surface of the ceramic core 9. An oil-impregnated layer 11 is provided inside the switch lever 3, and a metal rod 12 is installed inside the oil-impregnated layer 11. The knob 5 and the switching power supply 1 are rotatably connected, and the knob 5 is fixed to the ceramic core 9 by screws. The external structural dimensions of the ceramic rod 10 match the internal structural dimensions of the lever 6, and the ceramic rod 10 is fixedly inserted inside the lever 6. A heat dissipation hole 7 is provided on the left side of the knob 5 for heat dissipation.
[0025] Specifically, during use, the switch lever 3 is in the off state when it is down and in the on state when it is up. Rotating the knob 5 causes the lever 6 on the surface of the knob 5 to lift the switch lever 3 upward, thereby turning on the power supply 1. After the switch lever 3 is turned up, the lever 6 scrapes past the outside of the switch lever 3. When turning off the power supply 1, rotating the knob 5 clockwise downward will cause the lever 6 to move the switch lever 3 downward, thereby turning off the power supply 1 and shutting off the power.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
