[0043] The covering area of ​​the sealing plate 203 is larger than the cross-sectional area of ​​the pressure relief hole 201;

[0044] The size setting of the above components can ensure that the sealing plate 203 completely covers the pressure relief hole 201;

[0045] The housing protection assembly also includes a wiring hole 102 and a switching wire 103;

[0046] A wiring hole 102 is formed through the right side of the housing 101, and a switching wire 103 is fixedly connected to the left side of the housing 101;

[0048] The housing protection assembly also includes a rectangular frame 104;

[0049] A rectangular frame 104 is fixedly installed on the inner wall of the housing 101. There are two rectangular frames 104 in total. A conductive block 105 is fixedly connected between the rectangular frames 104. The side area of ​​the rectangular frame 104 is larger than the side area of ​​the conductive block 105.

[0050] The rectangular frame 104 can prevent the conductive block 105 from being directly connected to the inner wall of the housing 101, thereby providing a guarantee for heat dissipation;

[0051] Working principle: When the temperature inside the housing 101 rises, the butterfly screw 206 is removed from the first threaded hole 204 and the second threaded hole 205, and then the sealing plate 203 is rotated to expose the pressure relief hole 201, so that the heat inside the housing 101 is discharged through the pressure relief hole 201;

[0059] The setting of the slide bar 306 can assist the clamping plate 303 to slide up and down;

[0060] Working principle: insert the power cord into the wiring hole 102 and connect the conductive block 105 at the same time. At this time, the power cord is located between the first receiving plate 301 and the clamping plate 303. Then, rotate the threaded rod 305 at the threaded adjustment hole 304. At this time, the bottom end of the threaded rod 305 moves to the top of the clamping plate 303 until the power cord is clamped and fixed.

[0061] This step can realize the plugging of power cords with different diameters, thereby improving the applicability of the power adapter.
