[0033] Specifically, as Figure 6 shown, a through hole 6 is provided on the protective cover 501. The diameter of the through hole 6 is greater than the diameter of the cable 4. A spring groove 7 is provided on the through hole 6. A second spring 8 is provided in the spring groove 7. The other end of the second spring 8 is provided with a pressing plate 9.

[0037] When in use, first, the cable 4 is connected to the terminal block 3 and laid flat on the operating panel 2. Then, when the protective cover 501 is moved onto the operating panel 2, the terminal block 3 and the cable 4 can be covered inside the protective cover 501, which can effectively prevent electric shock accidents caused by accidental touch. At this time, the positioning block 502 on the protective cover 501 can enter the positioning groove 503 and squeeze the sliding rod 505, and then the first spring 509 is squeezed through the connecting plate 508 on the sliding rod 505, so that the first spring 509 is compressed in the fixing groove 507.

When the protective cover 501 needs to be opened, the sliding rod 505 needs to be pulled outward to disengage the sliding rod 505 from the limiting groove 506, so that the protective cover 501 can move upward, and then the through hole 6 can allow the cable 4 to pass through, avoiding the protective cover 501 from affecting the installation of the cable 4, and then when the cable 4 passes through the through hole 6 When the protective cover 501 is moved, the protective cover 501 can drive the limiting rod 13 to move in the limiting fixing groove 12, so that the protective cover 501 can be moved by the cooperation of the limiting rod 13 and the limiting fixing groove 12. The movement is more stable. When the protective cover 501 moves to the top of the limiting fixing groove 12, the limiting rod 13 can enter the transverse groove 14, and then the limiting rod 13 is fixed in the transverse groove 14, so as to fix the protective cover 501. Then, a tapered portion 16 is set at one end of the sliding rod 505, which can facilitate the positioning block 502 to squeeze the sliding rod 505, and facilitate the sliding rod 505 and the tapered portion 16 to enter the limiting groove 506. Then, the handle 19 can provide a fulcrum for the staff, so that the staff can move the protective cover 501 conveniently.

[0038] Specifically, Figure 4 As shown, an air inlet 10 is provided on the switching power supply body 1 , and a fan 11 is provided on the air inlet 10 . The fan 11 is fixed to the switching power supply body 1 by bolts.

[0039] Specifically, Figure 1 As shown, the switching power supply body 1 is provided with long heat dissipation holes 15 , and the number of the long heat dissipation holes 15 is several and they are evenly arranged on the switching power supply body 1 .

[0040] Specifically, Figure 4 As shown, the switching power supply body 1 is provided with extension plates 17 , the number of the extension plates 17 is four and they are symmetrically arranged, and the extension plates 17 are provided with fixing holes 18 .

[0041] When in use, the fan 11 can discharge the outside cold air into the inside of the switching power supply body 1, and then conduct heat exchange with the inside of the switching power supply body 1, and then discharge the heat through the long strip heat dissipation holes 15 to keep the temperature inside the switching power supply body 1 from being too high. Then, the combined use of the extension plate 17 and the fixing holes 18 can facilitate the fixing of the switching power supply body 1.

[0042] By adopting the above technical solution, it solves the problem of an existing switching power supply where the wiring connectors are exposed outside, ignoring the potential safety hazards that may be brought by accidental touch operations. Especially in public places such as homes, schools, and hospitals, children, the elderly, or people who are not familiar with electronic devices may touch the switching power supply out of curiosity or by mistake, resulting in electric shock accidents or other safety risks.

[0043] Working principle: When the present application is in use, first, the cable 4 is connected to the terminal block 3 and then laid flat on the operating panel 2. Then, when the protective cover 501 is moved onto the operating panel 2, the terminal block 3 and the cable 4 can be covered inside the protective cover 501, which can effectively prevent electric shock accidents caused by accidental touch. At this time, the positioning block 502 on the protective cover 501 can enter the positioning groove 503 and squeeze the sliding rod 505, and then the first spring 509 is squeezed through the connecting plate 508 on the sliding rod 505, so that the first spring 509 is compressed in the fixing groove 507. When the sliding rod 505 contacts the limiting groove 506, the first spring 50 9 restores its deformation, allowing the sliding rod 505 to enter the limiting groove 506, thereby fixing the positioning block 502 to prevent the protective cover 501 from being accidentally opened. When the protective cover 501 needs to be opened, the sliding rod 505 needs to be pulled outward to disengage the sliding rod 505 from the limiting groove 506, so that the protective cover 501 can move upward, and then the through hole 6 can allow the cable 4 to pass through, preventing the protective cover 501 from affecting the installation of the cable 4. Then, when the cable 4 passes through the through hole 6, the cable 4 can squeeze the squeezing plate 9, thereby causing the squeezing plate 9 to squeeze the second spring 8, so that the second spring 8 is compressed inside the spring groove 7, and the second spring 8 is compressed through the first spring groove 7. The force of the second spring 8 to restore the deformation acts in the opposite direction on the extrusion plate 9, so that the extrusion plate 9 fixes the cable 4, further increasing the stability of the cable 4. When the protective cover 501 needs to move, the protective cover 501 can drive the limit rod 13 to move in the limit fixing groove 12, so that the movement of the protective cover 501 is more stable through the cooperation of the limit rod 13 and the limit fixing groove 12. When the protective cover 501 moves to the top of the limit fixing groove 12, the limit rod 13 can enter the transverse groove 14, and then the limit rod 13 is fixed in the transverse groove 14, thereby fixing the protective cover 501, and then the sliding rod 50 5 is provided with a tapered portion 16, which can facilitate the positioning block 502 to squeeze the sliding rod 505, and facilitate the sliding rod 505 and the tapered portion 16 to enter the limiting groove 506, and then the handle 19 can provide a fulcrum for the staff to move the protective cover 501, and then the fan 11 can discharge the cold air from the outside into the interior of the switching power supply body 1, and then exchange heat with the interior of the switching power supply body 1, and then discharge the heat through the long heat dissipation hole 15, so as to keep the temperature inside the switching power supply body 1 not too high, and then the extension plate 17 and the fixing hole 18 are used in combination to facilitate the fixing of the switching power supply body 1.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
