The elastic metal sheets 208 span the electromagnet 204, and the electromagnet 204 is elastic and can be magnetically attracted;

[0033] A copper busbar 209 also extends from the ceramic column 207, and a connection terminal 210 is installed on the copper busbar 209;

[0034] A metal column is disposed at the center of the ceramic column 207 , and the elastic metal sheet 208 and the copper busbar 209 are both connected to the metal column.

[0035] Through the above technical scheme, a support frame 201 is arranged inside the power module body 1, and an extension wing 202 is arranged on the side of the support frame 201, and the positive and negative poles or the neutral and live wires of the power module body 1 are connected through the terminal 203 on the terminal 203, so that the electromagnet 204 is powered by the power module body 1, so that the magnetic suction head 205 generates magnetic adsorption and the elastic metal sheet 208 is deformed downward and contacts the conductive electrode 206 to achieve conductivity, and the current is output to the electrical equipment through the copper bus 209 and the terminal 210. When the power is turned on, the magnetic suction head 205 generates magnetic adsorption and the elastic metal sheet 208 is slowly deformed downward. When the power module body 1 is suddenly powered off, the magnetic suction head 205 changes its surface and loses its magnetism, so that the elastic metal sheet 208 slowly rebounds, thereby avoiding the suddenness of power supply and power off, achieving the effect of protecting the electrical equipment, and having a longer service life than electrical components such as capacitors.

[0036] Specifically, the support frame 201 is insulated as a whole and is made of high temperature resistant plastic.

[0037] Through the above technical solution, the support frame 201 is set as an insulator, thereby effectively improving the safety of the equipment.

[0038] Specifically, the magnetic head 205 protrudes from the top of the electromagnet 204 , and the magnetic head 205 occupies more than half of the top surface area of ​​the electromagnet 204 .

[0039] Through the above technical solution, the magnetic head 205 is protruded from the top of the electromagnet 204, so that the magnetic head 205 and the elastic metal sheet 208 can be closer, so that the magnetic head 205 can be more easily adsorbed to the elastic metal sheet 208, and the area of ​​the magnetic head 205 is set, so as to increase the magnetic attraction area.

[0040] Specifically, the conductive electrodes 206 are all made of metal iron, and the top of the conductive electrode 206 exceeds the top of the magnetic suction head 205 .

[0041] Through the above technical solution, the conductive electrode 206 is made of metal copper, so that when the conductive electrode 206 contacts the elastic metal sheet 208, the conductivity can be uniform, and the preparation cost of the device can be reduced;

[0046] Through the above technical solution, the connection terminal 210 is arranged to protrude from one end of the power module body 1, so that it can be directly connected to the electrical equipment without arranging a connection component at the end of the power module body 1 for wiring.

[0047] Specifically, the outer surface of the power module body 1 is fixedly connected with heat dissipation fins 3 , and the heat dissipation fins 3 are a plurality of thin sheets.

[0048] Through the above technical solution, heat dissipation fins 3 are provided on the outer surface of the power module body 1 , the purpose of which is to improve the heat dissipation effect of the power module body 1 .

[0049] When in use, by setting a support frame 201 inside the power module body 1, and setting an extension wing 202 on the side of the support frame 201, the positive and negative poles or the neutral and live wires of the power module body 1 are connected through the terminal 203 on the terminal 203, so that the electromagnet 204 is powered by the power module body 1, so that the magnetic suction head 205 generates magnetic adsorption and the elastic metal sheet 208 is deformed downward and contacts the conductive electrode 206 to achieve conductivity, and the current is output to the electrical equipment through the copper bus 209 and the terminal 210. When the power is turned on, the magnetic suction head 205 generates magnetic adsorption and the elastic metal sheet 208 is slowly deformed downward. When the power module body 1 is suddenly powered off, the magnetic suction head 205 loses its magnetism and the elastic metal sheet 208 slowly rebounds, thereby avoiding the suddenness of power supply and power off, achieving the effect of protecting the electrical equipment, and having a longer service life than electrical components such as capacitors;

[0050] By setting the top of the conductive electrode 206 to be higher than the top of the magnetic head 205, after the magnetic head 205 is energized to generate magnetism, the elastic metal sheet 208 and the magnetic head 205 will not contact each other due to the obstruction of the conductive electrode 206, thereby avoiding the problem of the elastic metal sheet 208 conducting current to the magnetic head 205 and causing the electromagnet 204 to short-circuit, thereby achieving the effect of protecting the electromagnet 204.
