A conductive sheet 306 is fixedly connected to the side of the mounting hole 302 corresponding to the position of the conductive contact 303, a hot melt pin 304 is fixedly connected to the bottom end of the mounting hole 302, a fixing hole is opened at the bottom end of the conductive contact 303 corresponding to the position of the hot melt pin 304, the top of the hot melt pin 304 is fixedly connected to the bottom end of the fixing hole, during normal use, the conductive contact 303 contacts the conductive sheet 306 so that the connecting jack 305 is connected to the internal circuit of the power supply body 101, and at the same time, the hot melt pin 304 is inserted into the fixing hole at the bottom of the conductive contact 303 to fix the conductive contact 303, so that the compression springs 307 on both sides are in a compressed state, a short circuit occurs in the power supply mechanism 1, heat is generated to disconnect the hot melt pin 304, and the compression spring 307 pushes the conductive contact 303 to separate the conductive contact 303 from the conductive sheet 306, so that the power supply mechanism 1 is disconnected from the external electronic equipment to avoid damage.

[0026] A heat sink 103 is fixedly connected to the side of the power source body 101 . The heat sink 103 is made of aluminum alloy. The heat sink 103 increases the contact area between the power source body 101 and the air, thereby accelerating the heat dissipation of the power source mechanism 1 .

[0027] Among them, a slide groove 104 is opened on the side of the storage groove 102, and the dustproof mechanism 4 includes a first dustproof plate 401, and the side of the first dustproof plate 401 is movably connected to the side of the slide groove 104, and the side of the slide groove 104 is movably connected to the second dustproof plate 402. When not in use, the bottom end of the first dustproof plate 401 contacts the top end of the second dustproof plate 402 to block the storage groove 102 and prevent dust from entering the wiring structure 3 to cause poor contact. When in use, the first dustproof plate 401 is pushed upward along the slide groove 104 and the second dustproof plate 402 is pushed downward to facilitate connecting the power supply mechanism 1 to the circuit through the connecting jack 305.

[0028] Among them, a first mounting groove 105 is opened at the top of the slide groove 104, and the top of the first mounting groove 105 is fixedly connected with a first return spring 403, and the bottom end of the first return spring 403 is fixedly connected to the top of the first dustproof plate 401, and a second mounting groove 106 is opened at the bottom end of the slide groove 104, and the bottom end of the second mounting groove 106 is fixedly connected with a second return spring 404, and the top end of the second return spring 404 is fixedly connected to the bottom end of the second dustproof plate 402.

[0029] Among them, a sealing groove 405 is opened at the bottom end of the first dustproof plate 401, and a first arc angle 407 is opened at the bottom end of the sealing groove 405. The top of the second dustproof plate 402 is fixedly connected with a sealing block 406, and a second arc angle 408 is opened at the top of the sealing block 406. When the bottom end of the first dustproof plate 401 contacts the top end of the second dustproof plate 402, the first arc angle 407 and the second arc angle 408 facilitate the insertion of the sealing block 406 into the sealing groove 405, thereby avoiding the formation of a gap between the first dustproof plate 401 and the second dustproof plate 402.

[0030] The fire extinguishing mechanism 2 includes a mounting box 201, the bottom end of the mounting box 201 is fixedly connected to the top of the power supply body 101, a first through hole 202 is provided at the top of the mounting box 201, a pressure spring 207 is fixedly connected to the inner wall of the side of the mounting box 201, a bottom plate 205 is fixedly connected to the side of the pressure spring 207, a baffle 204 is fixedly connected to the side of the bottom plate 205, the top of the baffle 204 is movably connected to the inner wall of the top of the mounting box 201, a second through hole 203 is provided at the top of the baffle 204, and a heat expansion fire extinguishing agent is installed inside the mounting box 201. When the power supply mechanism 1 is operating normally, the pressure spring 207 pushes the bottom plate 205 so that the side of the baffle 204 is tightly attached to the inner wall of the side of the installation box 201 and the second through hole 203 is staggered with the first through hole 202, so as to avoid leakage of the thermal expansion fire extinguishing agent inside the installation box 201. When a short circuit occurs in the power supply mechanism 1, the temperature rises, so that the thermal expansion fire extinguishing agent inside the installation box 201 expands and increases the pressure on the bottom plate 205, so that the baffle 204 moves to the left, so that the second through hole 203 coincides with the first through hole 202, and the thermal expansion fire extinguishing agent inside the installation box 201 is sprayed out to cool down and extinguish the fire.

[0031] The inner wall of the bottom end of the installation box 201 is fixedly connected with a limiting plate 206 , which limits the bottom plate 205 to ensure that the second through hole 203 overlaps with the first through hole 202 when the bottom plate 205 contacts the limiting plate 206 .

[0032] The working principle of the utility model is as follows: when the power supply mechanism 1 is not in use, the pressure spring 207 pushes the bottom plate 205 so that the side of the baffle 204 is close to the side inner wall of the installation box 201 and the second through hole 203 is staggered with the first through hole 202 to avoid leakage of the heat expansion fire extinguishing agent inside the installation box 201, and the conductive contact 303 is in contact with the conductive sheet 306 so that the connecting jack 305 is connected to the internal circuit of the power supply body 101, and at the same time, the hot melt pin 304 is inserted into the fixing hole at the bottom of the conductive contact 303 to fix the conductive contact 303, and the second reset spring 404 pushes the second dustproof plate 402 upward, and the sealing block 406 is conveniently inserted into the sealing groove 405 through the first arc angle 407 and the second arc angle 408 to avoid the first dustproof plate 401 and the second dustproof plate 401. A gap appears between the dust plates 402 to prevent dust from entering the storage slot 102. It is necessary to push the first dust plate 401 upward along the slide slot 104 and push the second dust plate 402 downward to facilitate connecting the power supply mechanism 1 to the circuit through the connecting jack 305. When a short circuit occurs in the equipment and the temperature rises, the hot melt pin 304 is disconnected, and the compression spring 307 pushes the conductive contact 303 to separate the conductive contact 303 from the conductive sheet 306, so that the power supply mechanism 1 is disconnected from the external electronic device to avoid damage. At the same time, the expansion of the thermal expansion fire extinguishing agent inside the installation box 201 increases the pressure on the bottom plate 205, causing the baffle 204 to move to the left, thereby causing the second through hole 203 to overlap with the first through hole 202, and the thermal expansion fire extinguishing agent inside the installation box 201 is sprayed out to cool down and extinguish the fire.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
