[0002] A switching power supply is a power supply that uses modern power electronics technology to control the time ratio of the switch on and off to maintain a stable output voltage. A switching power supply is generally composed of a pulse width modulation (PWM) control IC and a MOSFET. With the development and innovation of power electronics technology, switching power supply technology is also constantly innovating. At present, switching power supplies are widely used in almost all electronic devices due to their small size, light weight and high efficiency. They are an indispensable power supply method for the rapid development of today's electronic information industry.

[0003] When using an existing LED switching power supply, it is usually connected to the line through a wiring port. However, the existing LED switching power supply cannot protect the wiring terminal, resulting in the wiring terminal being exposed to the outside. There are great safety hazards when using it, and the line connected to the wiring terminal is not reinforced, which can easily cause the connected line to fall off, thereby affecting the normal use of the switching power supply and affecting work efficiency. Utility Model Content

A semi-potted self-heating LED switching power supply is proposed.

[0010] Preferably, a plurality of ventilation holes are formed through the top of the power source body, and a plurality of through holes are formed through the surface of the protective cover.

[0011] Preferably, the rubber pressing plate corresponds to the wiring seat, and the through hole corresponds to the wiring seat.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, a protective cover, a spring and a rubber pressing plate are provided. When in use, the hinge can drive the protective cover to rotate and close the protective cover, thereby protecting the wiring seat to prevent dust and dirt from damaging the wiring seat, thereby extending its service life and reducing safety risks.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Example 1

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a semi-potted self-heating LED switching power supply, comprising a power supply body 1, two hinges 12 are arranged on the top of the power supply body 1, one end of the hinge 12 is connected to a protective cover plate 13, a plurality of brackets 16 are arranged on the inner side of the protective cover plate 13, a telescopic rod 17 is fixedly connected to the bottom of the bracket 16, a spring 18 is sleeved on the outer side of the telescopic rod 17, and a rubber pressing plate 19 is connected to the bottom of the telescopic rod 17.

[0024] In this embodiment, the hinge 12 can drive the protective cover 13 to rotate and close the protective cover 13, thereby protecting the terminal block 15 and preventing dust and dirt from damaging the terminal block 15, thereby extending its service life and reducing safety risks. The bracket 16 can be used to fix the telescopic rod 17 above the line interface 20. Through the telescopic characteristics of the telescopic rod 17 and the spring 18, the rubber pressure plate 19 can be squeezed to fit the outside of the line connected to the line interface 20, thereby fixing the line to prevent it from falling off, thereby improving the overall stability of the device and improving work efficiency.

[0027] In this embodiment, the micro motor 8 can be fixed by the fixing plate 7 to maintain its stable operation. The micro motor 8 drives the rotating shaft 9 to operate, and then the rotating shaft 9 drives the fan blades 10 to rotate to generate fresh air. The fresh air flows on the inside of the air duct 6 and enters the power supply body 1 through the air inlet 5 to dissipate heat and cool the internal structure of the power supply body 1, thereby maintaining the stable operation of the switching power supply, reducing the burden on electronic components, extending the service life of the switching power supply, and effectively improving the heat dissipation and cooling performance of the switching power supply. The high-temperature airflow generated by the internal operation of the power supply body 1 can be discharged through the vent 2 to maintain the basic heat dissipation and ventilation of the power supply body 1. The normal ventilation and air exchange inside the air duct 6 can be guaranteed through the air inlet 11, thereby maintaining the stable operation of the micro motor 8 and extending its service life. The circuit board 3 and the capacitor 4 are both basic components of the LED switching power supply, which are prior arts and will not be described in detail below.

[0028] The working principle of this embodiment is as follows: when in use, first prepare the lines to be connected, then connect the lines to the line interfaces 20 in turn, after the connection is completed, move the protective cover 13 so that the hinge 12 is forced to drive the protective cover 13 to rotate, and the line is clamped in the through hole 14, and at the same time, the telescopic rod 17 and the spring 18 apply pressure downward to make the rubber pressing plate 19 fit the outside of the connecting line to completely fix the line, and then start the power supply body 1 and put it into use. Finally, when the power supply body 1 runs for a long time and generates high temperature, start the micro motor 8, and the micro motor 8 drives the rotating shaft 9 to rotate, and then the rotating shaft 9 drives the fan blades 10 to rotate to generate fresh air. The fresh air flows from the inner side of the air duct 6 to one end thereof, and enters the inside of the power supply body 1 from the air inlet 5, and cools and dissipates the electronic components such as the circuit board 3 and the capacitor 4 inside the power supply body 1. The high-temperature hot air rises until it is discharged from the inside of the power supply body 1 from the vent 2, thereby completing the use of the LED switching power supply.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
