The lower end of the seat body is provided with a junction box, and a plug is provided inside the junction box. The right end of the three-hole socket is provided with a two-hole socket, and a plug is installed below the three-hole socket. The inner surface of the two-hole socket is provided with insulating glue, and a plug is provided between the insulating glue. A panel is installed above the junction box, and a sealing plate is installed on the outside of the panel. The left and right ends of the lower side of the sealing plate are provided with buckle holes, and wire holes are installed between the buckle holes.

The smart switch waterproof socket is provided with an insulating glue with an elastic structure, which can wrap the plug iron sheet tightly when the plug is inserted, effectively preventing water from entering the socket.

[0004] In the process of realizing the above invention, the inventors found that there are at least the following problems in the prior art that have not been solved: the invention does not take into account that when the socket is overloaded, the wires will overheat, which may damage the device or even cause a fire; when the plug is unplugged, due to the first rotor, the plug is not easy to unplug, which is inconvenient to use.

[0005] Therefore, an intelligent switch socket is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide an intelligent switch socket, which can prevent debris from entering the socket through the linkage of two second sliders, prevent electric shock and protect personal safety. When the plug is pulled out, the button is pressed and the spring block will pop out to lift the plug, making it easy to pull out. When the socket is used for too long or the current is too large in a short time, the double-layer metal sheet is heated and bent to disconnect the circuit, protecting the device and the environment, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] An intelligent switch socket comprises a socket shell, wherein a device cavity is provided inside the socket shell, a device plate is fixedly installed on the top of the device cavity, horizontal plates are symmetrically fixedly installed on the two side walls of the device cavity, an electric socket is fixedly installed on the bottom of the device cavity, two conductive blocks are symmetrically provided on the upper surface of the electric socket, a jack is provided in the middle of the device plate, a protection mechanism for preventing accidental touch is provided in the middle of the device cavity, an elastic mechanism for facilitating pulling out the plug is provided on one side of the device plate, and a power-off mechanism for preventing the socket from overloading is provided on one side of the bottom of the device cavity.

[0009] Through the linkage of the two second sliders, foreign objects can be prevented from entering the socket, thereby preventing electric shock and protecting personal safety. When the plug is unplugged, press the button and the spring block will pop out to lift the plug, making it easier to unplug. When the socket is used for too long or the current is too large in a short time, the double-layer metal sheet will bend due to heat to disconnect the line, thereby protecting the device and the environment.

[0010] Preferably, the protection mechanism includes a fixed block fixedly mounted on the bottom wall of the device plate, a circular tube fixedly mounted in the middle of the fixed block, movement cavities symmetrically provided on both sides of the interior of the fixed block, rotating rods are rotatably installed in the middle of the two movement cavities, gear sleeves are provided at both ends of the two rotating rods, an active rod and a driven rod are slidably connected on both sides of the circular tube, the active rod and the driven rod both extend into the movement cavity, one end of the two active rods are fixedly connected to a rack, one end of the two driven rods are fixedly connected to the rack, the active rod and the driven rod are meshed with the rotating rod through the rack and the gear sleeve, one end of the two active rods are elastically connected to the inner wall of the fixed block through a third spring, a deep groove is provided on one side of the two cross plates, the inner walls of the two deep grooves are fixedly connected to a first spring, the other ends of the two first springs are fixedly connected to a first slider, a circular plate is fixedly mounted in the middle of the circular tube, the two outer surfaces of the circular plate are fixedly connected to a second spring, and the other ends of the two second springs are fixedly connected to a second slider.

[0011] When the plug is inserted into the device cavity from the two jacks, the first sliders on both sides of the device cavity are squeezed and then squeezed the first spring, and the two second sliders are also squeezed. The ends of the two active rods close to the sliders are round headed, and the sides of the two second sliders close to the active rods are arcuate. Therefore, the two second sliders can squeeze the active rods to move up at the same time, and the upward movement of the active rods drives the rotating rod to rotate through the gear meshing. The rotation of the rotating rod drives the driven rod to move up at the same time through the gear meshing. The upward movement of the driven rod will not hinder the movement of the two second sliders. Since the two second sliders move at the same time, the two second sliders can be squeezed smoothly at the same time. When only the second slider on one side is squeezed, the second slider on the other side is not squeezed, resulting in the active rod on the other side cannot move, and thus cannot drive the driven rod on one side to move. One end of the driven rod is a rectangular parallelepiped and cannot be squeezed up by the second slider, so that the second slider on the squeezed side is stuck, preventing debris from entering the device cavity and protecting the device. Due to the elastic force of the first spring and the elastic force of the second spring, when the plug enters, the plug is firmly clamped by the first slider and the second slider on both sides.

[0012] Preferably, the elastic mechanism includes a first slide groove provided on one side of the device plate, the bottom wall of the first slide groove is fixedly connected to a fourth spring, the other end of the fourth spring is fixedly connected to a slide plate, and the other end of the slide plate is fixedly connected to a pressing block, a second slide groove is provided on one side of the device plate, a circular groove for connecting the first slide groove and the second slide groove is provided inside the device plate, a clamping rod is fixedly connected to one side wall of the first slide groove, one end of the clamping rod is rotatably connected to a traction rod, one end of the traction rod is provided with a circular hole, the traction rod is slidably connected to the push rod through the clamping block, a fixing plate is fixedly installed at the middle of the circular groove, the other end of the push rod passes through the fixing plate and is fixedly connected to a sliding rod, one end of the sliding rod is provided with a clamping groove, the push rod is elastically connected to the fixing plate through a sixth spring, a fixing rod is fixedly installed at the bottom of the second slide groove, a fifth spring is sleeved on the outer edge of the fixing rod, one end of the fifth spring is fixedly connected to a spring block, one end of the spring block is provided with a spring groove, one end of the fixing rod extends into the spring groove, and a bayonet is fixedly connected to the side wall of the spring block.

[0013] When the plug is inserted into the jack, the plug will also press the spring block to move downward until the pin is stuck by one end of the slide rod. The spring block is elastically connected to the bottom wall of the second slide groove through the fifth spring. At this time, the fifth spring is in a compressed state. When you want to pick up the plug, press the button block, and the button block moves downward to drive the slide plate to move downward. The slide plate moves back and pushes the traction rod to rotate around the card rod. The rotation of the traction rod drives the push rod to move through the cooperation of the card block, and the movement of the push rod drives the slide bar to move. The movement of the slide bar makes the pin unstuck, and the spring block is pushed up by the elastic force of the fifth spring itself, and then the plug is lifted, which makes it convenient to pull out the plug. Under the elastic force of the fourth and sixth springs, the button block can reset itself after being pressed and the slide bar moves.

[0014] Preferably, the power-off mechanism includes a switch fixedly mounted on one side of the socket housing, one end of the switch is fixedly connected to a vertical rod, the outer edge of the vertical rod is sleeved with a seventh spring, one end of the vertical rod is fixedly connected to a conductive head, one side of the electric socket is fixedly connected to a first wire and a second wire, the other end of the first wire is fixedly connected to an inner wall of the socket housing, the inner wall of the socket housing is fixedly connected to a third wire, the other ends of the third wire and the second wire are both fixedly connected to an arc-shaped conductive sheet, the two arc-shaped conductive sheets are elastically connected to the conductive head, a double-layer metal sheet is fixedly mounted on the middle part of the vertical rod, the double-layer metal sheet is elastically connected to the switch through the seventh spring, both ends of the double-layer metal sheet are fixedly connected to heat-conducting sheets, and the other ends of the two heat-conducting sheets are in close contact with the second wire and the third wire.

[0015] The switch can be used to check whether the socket has electricity. When the switch is pressed, the switch drives the vertical rod to move, and the vertical rod moves with the conductive head inserted into the middle of the second wire and the third wire. Since the arc-shaped conductive sheet has a certain elasticity, the arc-shaped conductive sheets on both sides will clamp the conductive head, so that the arc-shaped conductive sheet and the conductive head can be in close contact and then energized. The vertical rod will also move with the heat conductive sheet, so that the heat conductive sheet is in close contact with the second wire and the third wire. When the socket works for too long or does not work properly, causing the current flowing through the wire to suddenly increase, the wire will heat up, which will accelerate the aging of the wire and damage the device. The heat generated by the heating of the second wire and the third wire will pass through the socket. The heat is transferred to the double-layer metal sheet through the thermal conductive sheet. The materials of the active layer of the double-layer metal sheet mainly include manganese-nickel-copper alloy, nickel-chromium-iron alloy, nickel-manganese-iron alloy and nickel, and the material of the passive layer is mainly nickel-iron alloy with a nickel content of 30-45%. The active layer of the double-layer metal sheet has a higher expansion coefficient, and the passive layer has a lower expansion coefficient. Since the expansion coefficients between the two layers are not uniform, the double-layer metal sheet is deformed. Because the second and third wires are rigid materials, under the reaction force of the second and third wires, the double-layer metal sheet bends and drives the vertical rod to move, so that the conductive head is separated from the arc-shaped conductive sheets on both sides, thereby achieving the purpose of disconnecting the circuit and protecting the device.

[0016] Preferably, the material of the heat conducting sheet is AIN ceramic.

[0017] AlN ceramic aluminum nitride is a covalent bond compound and a ceramic material with excellent comprehensive performance. Its thermal conductivity is 8 to 10 times that of Al2O3, and its price is much lower than that of cubic boron nitride. The required sintering aid does not have the toxicity of beryllium oxide (BeO). Due to a series of excellent properties such as high thermal conductivity, strong heat resistance, low dielectric constant and loss, and linear expansion coefficient matching Si, AlN is regarded as the most promising new generation of excellent insulating heat dissipation substrate materials.

[0018] Preferably, a liquid box is fixedly installed inside the movement cavity, the liquid box contains magnetorheological fluid, and the rotating rod passes through the liquid box.

[0019] When the socket leaks electricity, it will generate strong electromagnetic induction lines. At this time, the magnetorheological fluid inside the liquid box will change from liquid to solid, the rotating rod will not be able to rotate, and the plug will not be able to be inserted into the socket.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The two second sliders are linked and can only move when they are squeezed at the same time. If only one of them is squeezed, it will not move, which prevents foreign debris from entering and can also protect the safety of children.

[0022] 2. Press the button, the spring block moves upward, and then lifts the plug, making it easier to pull out the plug. Under the elastic force of the fourth spring and the sixth spring, the button can reset itself after being pressed and the slide rod moves.

[0023] 3. When the socket works for too long or does not work properly, causing the current flowing through the wire to suddenly increase, the wire will heat up, causing the wire to age faster and causing damage to the device. The heat generated by the second and third wires will transfer the heat to the double-layer metal sheet through the heat conductive sheet. The double-layer metal sheet will deform due to heat and drive the vertical rod to move, causing the conductive head to separate from the arc-shaped conductive sheets on both sides, thereby achieving the purpose of disconnecting the circuit and protecting the device.

[0024] 4. When the socket leaks electricity, it will generate strong electromagnetic induction lines. At this time, the magnetorheological fluid inside the liquid box will change from liquid to solid, the rotating rod will not be able to rotate, and the plug will not be able to be inserted into the socket.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] See also Figures 1 to 7 The present invention provides an intelligent switch socket, and the technical solution is as follows.

[0037] A smart switch socket includes a socket shell 1, a device cavity 2 is opened inside the socket shell 1, a device plate 9 is fixedly installed on the top of the device cavity 2, horizontal plates 4 are symmetrically fixedly installed on the two side walls of the device cavity 2, an electric socket 7 is fixedly installed on the bottom of the device cavity 2, two conductive blocks 8 are symmetrically arranged on the upper surface of the electric socket 7, a jack 3 is opened in the middle of the device plate 9, a protection mechanism for preventing accidental touch is arranged in the middle of the device cavity 2, an elastic mechanism for facilitating pulling out the plug is arranged on one side of the device plate 9, and a power-off mechanism for preventing the socket from overloading is arranged on one side of the bottom of the device cavity 2.

[0038] Through the linkage of the two second sliders 11, foreign objects can be prevented from entering the socket, thereby preventing electric shock and protecting personal safety. When the plug is unplugged, the button 19 is pressed, and the spring block 23 will pop out to lift the plug, making it easy to unplug. When the socket is used for too long or the current is too large in a short time, the double-layer metal sheet 45 is bent by heat to disconnect the circuit, thereby protecting the device and the environment.

[0039] As an embodiment of the present invention, refer to Figure 2 , Figure 3 and Figure 4The protection mechanism includes a fixed block 10 fixedly mounted on the bottom wall of the device plate 9, a round tube 13 is fixedly mounted in the middle of the fixed block 10, and movement chambers 48 are symmetrically opened on both sides of the interior of the fixed block 10. Rotating rods 17 are rotatably mounted in the middle of the two movement chambers 48, and gear sleeves 14 are provided at both ends of the two rotating rods 17. Active rods 15 and driven rods 16 are slidably connected on both sides of the round tube 13. The active rods 15 and driven rods 16 extend into the movement chamber 48, and one end of the two active rods 15 is fixedly connected to a rack, and one end of the two driven rods 16 is fixedly connected to a gear sleeve. The active rod 15 and the driven rod 16 are meshed with the rotating rod 17 through the rack and the gear sleeve 14. One end of the two active rods 15 is elastically connected to the inner wall of the fixed block 10 through the third spring 18. A deep groove 49 is opened on one side of the two cross plates 4. The inner walls of the two deep grooves 49 are fixedly connected with the first springs 5. The other ends of the two first springs 5 ​​are fixedly connected with the first slider 6. A circular plate 50 is fixedly installed in the middle of the circular tube 13. The two outer surfaces of the circular plate 50 are fixedly connected with the second springs 12. The other ends of the two second springs 12 are fixedly connected with the second slider 11.

[0040] When the plug is inserted into the device cavity 2 from the two jacks 3, the first sliders 6 on both sides of the device cavity 2 are squeezed and then squeeze the first spring 5, and the two second sliders 11 are also squeezed. The ends of the two active rods 15 close to the second sliders 11 are rounded, and the sides of the two second sliders 11 close to the active rod 15 are arc-shaped. Therefore, when the two second sliders 11 squeeze the active rod 15, the contact point is a point, and the second slider 11 exerts an upward force on the active rod 15 to make the active rod 15 move up. The upward movement of the active rod 15 drives the rotating rod 17 to rotate through the gear meshing. The rotation of the rotating rod 17 drives the driven rod 16 to move up through the gear meshing at the same time, and the upward movement of the driven rod 16 will not hinder the two second sliders The movement of the block 11, since the two second sliders 11 move at the same time, the two second sliders 11 can be squeezed smoothly at the same time. When only the second slider 11 on one side is squeezed, since the second slider 11 on the other side is not squeezed, the active rod 15 on the other side cannot move, and thus cannot drive the driven rod 16 on one side to move. One end of the driven rod 16 is in the shape of a rectangular parallelepiped and cannot be squeezed and moved up by the second slider 11, so that the second slider 11 on the squeezed side is stuck, preventing debris from entering the device cavity 2 and protecting the device. Due to the elastic force of the first spring 5 and the elastic force of the second spring 12, when the plug enters, the plug is firmly clamped by the first slider 6 and the second slider 11 on both sides.

[0041] As an embodiment of the present invention, refer to Figure 3 , Figure 5 , Figure 6 and Figure 7The elastic mechanism includes a first slide groove 20 opened on one side of the device plate 9, a fourth spring 21 is fixedly connected to the bottom wall of the first slide groove 20, a slide plate 22 is fixedly connected to the other end of the fourth spring 21, and a pressing block 19 is fixedly connected to the other end of the slide plate 22. A second slide groove 26 is opened on one side of the device plate 9, and a circular groove 31 for connecting the first slide groove 20 and the second slide groove 26 is opened inside the device plate 9. A clamping rod 29 is fixedly connected to one side wall of the first slide groove 20, and one end of the clamping rod 29 is rotatably connected to a traction rod 27. A circular hole 51 is opened at one end of the traction rod 27, and the traction rod 27 passes through the clamping block 28. A fixing plate 32 is fixedly installed in the middle of the circular groove 31 and is slidably connected to the push rod 30. The other end of the push rod 30 passes through the fixing plate 32 and is fixedly connected to the sliding rod 34. A locking groove 35 is provided at one end of the sliding rod 34. The push rod 30 is elastically connected to the fixing plate 32 through the sixth spring 33. A fixing rod 25 is fixedly installed at the bottom of the second sliding groove 26. A fifth spring 24 is sleeved on the outer edge of the fixing rod 25. One end of the fifth spring 24 is fixedly connected to the spring block 23. A spring groove 52 is provided at one end of the spring block 23. One end of the fixing rod 25 extends into the spring groove 52. A bayonet pin 36 is fixedly connected to the side wall of the spring block 23.

[0042] When the plug is inserted into the jack 3, the plug will also press the spring block 23 to move downward until the latch pin 36 is stuck by one end of the slide bar 34. The spring block 23 is elastically connected to the bottom wall of the second slide slot 26 through the fifth spring 24. At this time, the fifth spring 24 is in a compressed state. When you want to pick up the plug, press the button 19, and the button block 19 moves downward to drive the slide plate 22 to move downward. The slide plate 22 moves back and pushes the traction rod 27 to rotate around the latch rod 29. The rotation of the traction rod 27 drives the push rod 30 to move through the cooperation of the latch block 28. The movement of the push rod 30 drives the slide bar 34 to move. The movement of the slide bar 34 makes the latch pin 36 not stuck. The elastic force of the fifth spring 24 itself pushes the spring block 23 to move upward, and then lifts the plug to facilitate the plug to be pulled out. Under the elastic force of the fourth spring 21 and the sixth spring 33, the button block 19 can reset itself after being pressed and the slide bar 34 moves.

[0043] As an embodiment of the present invention, refer to Figure 3The power-off mechanism includes a switch 44 fixedly mounted on one side of the socket housing 1, one end of the switch 44 is fixedly connected to a vertical rod 46, the outer edge of the vertical rod 46 is sleeved with a seventh spring 43, one end of the vertical rod 46 is fixedly connected to a conductive head 41, one side of the electric socket 7 is fixedly connected to a first wire 37 and a second wire 38, the other end of the first wire 37 is fixedly connected to the inner wall of the socket housing 1, the inner wall of the socket housing 1 is fixedly connected to a third wire 39, the other ends of the third wire 39 and the second wire 38 are fixedly connected to an arc-shaped conductive sheet 40, the two arc-shaped conductive sheets 40 are elastically connected to the conductive head 41, a double-layer metal sheet 45 is fixedly mounted in the middle of the vertical rod 46, the double-layer metal sheet 45 is elastically connected to the switch 44 through the seventh spring 43, both ends of the double-layer metal sheet 45 are fixedly connected to heat-conducting sheets 42, and the other ends of the two heat-conducting sheets 42 are in close contact with the second wire 38 and the third wire 39.

[0044] The switch 44 can be used to check whether the socket has electricity. When the switch 44 is pressed, the switch 44 drives the vertical rod 46 to move. The vertical rod 46 moves with the conductive head 41 and inserts it between the second wire 38 and the third wire 39. Since the arc-shaped conductive sheet 40 has a certain elasticity, the arc-shaped conductive sheets 40 on both sides will clamp the conductive head 41, so that the arc-shaped conductive sheet 40 and the conductive head 41 can be in close contact and then energized. The vertical rod 46 will also move with the heat conductive sheet 42, so that the heat conductive sheet 42 is in close contact with the second wire 38 and the third wire 39. When the socket works for too long or does not work properly, causing the current flowing through the wire to suddenly increase, the wire will heat up, which will accelerate the aging of the wire and damage the device, causing the second wire 38 and the third wire 39 to be damaged. The heat generated by the heat is transferred to the double-layer metal sheet 45 through the heat conductive sheet 42. The materials of the active layer of the double-layer metal sheet 45 mainly include manganese-nickel-copper alloy, nickel-chromium-iron alloy, nickel-manganese-iron alloy and nickel, and the material of the passive layer is mainly nickel-iron alloy with a nickel content of 30-45%. The active layer expansion coefficient of the double-layer metal sheet 45 is relatively high, and the passive layer expansion coefficient is relatively low. Since the expansion coefficients between the two layers are not uniform, the double-layer metal sheet 45 is deformed. Since the second wire 38 and the third wire 39 are made of rigid materials, under the reaction force of the second wire 38 and the third wire 39, the double-layer metal sheet 45 bends and drives the vertical rod 46 to move, so that the conductive head 41 is separated from the arc-shaped conductive sheets 40 on both sides, thereby achieving the purpose of disconnecting the circuit and protecting the device.

[0045] As an embodiment of the present invention, refer to Figure 3 The material of the heat conducting sheet 42 is AIN ceramic.

[0046] AlN ceramic aluminum nitride is a covalent bond compound and a ceramic material with excellent comprehensive performance. Its thermal conductivity is 8 to 10 times that of Al2O3, and its price is much lower than that of cubic boron nitride. The required sintering aid does not have the toxicity of beryllium oxide (BeO). Due to a series of excellent properties such as high thermal conductivity, strong heat resistance, low dielectric constant and loss, and linear expansion coefficient matching with Si, AlN is regarded as the most promising new generation of excellent insulating heat dissipation substrate materials.

[0047] As an embodiment of the present invention, refer to Figure 2 A liquid box 47 is fixedly installed at the lower end of the fixed block 10 . The liquid box 47 contains magnetorheological fluid, and the rotating rod 17 passes through the liquid box 47 .

[0048] When the socket leaks electricity, it will generate strong electromagnetic induction lines, and the magnetorheological fluid inside the liquid box 47 will change from liquid to solid, the rotating rod 17 will not be able to rotate, and the plug will not be able to be inserted into the socket 3.

[0049] Working principle: when the plug is inserted into the device cavity 2 from the two sockets 3, the first sliders 6 on both sides of the device cavity 2 are squeezed and then squeeze the first spring 5, and the two second sliders 11 will also be squeezed. The ends of the two active rods 15 close to the second sliders 11 are rounded, and the sides of the two second sliders 11 close to the active rod 15 are arc-shaped. Therefore, when the two second sliders 11 squeeze the active rod 15, the contact point is a point. The second slider 11 exerts an upward force on the active rod 15 to make the active rod 15 move up. The upward movement of the active rod 15 drives the rotating rod 17 to rotate through the gear meshing. The rotation of the rotating rod 17 drives the driven rod 16 to move up through the gear meshing at the same time. The upward movement of the driven rod 16 will not hinder the movement of the two second sliders 11. The second sliders 11 move simultaneously, so that the two second sliders 11 can be squeezed smoothly at the same time. When only the second slider 11 on one side is squeezed, since the second slider 11 on the other side is not squeezed, the active rod 15 on the other side cannot move, and thus cannot drive the driven rod 16 on one side to move. One end of the driven rod 16 is in a rectangular shape and cannot be squeezed and moved upward by the second slider 11, so that the second slider 11 on the squeezed side is stuck, preventing debris from entering the device cavity 2 and protecting the device. Due to the elastic force of the first spring 5 and the elastic force of the second spring 12, when the plug enters, the plug is firmly clamped by the first slider 6 and the second slider 11 on both sides. When the plug is inserted into the socket 3, the plug will also press the spring block 23 downward to move downward. The fifth spring 24 is in a state of compression at this time. When the plug is to be lifted, the push block 19 is pressed, and the push block 19 moves downward to drive the slide plate 22 downward. The slide plate 22 moves back and pushes the traction rod 27 to rotate around the clamping rod 29. The rotation of the traction rod 27 drives the push rod 30 to move through the cooperation of the clamping block 28. The movement of the push rod 30 drives the slide bar 34 to move. The movement of the slide bar 34 makes the pin 36 unstuck. The elastic force of the fifth spring 24 pushes the spring block 23 upward, and then lifts the plug to facilitate the removal of the plug. Under the elastic force of the fourth spring 21 and the sixth spring 33, the push block 19 is pressed and the slide bar 3 4 can be reset automatically after moving, and the switch 44 can be used to check whether the socket is powered. When the switch 44 is pressed, the switch 44 drives the vertical rod 46 to move, and the vertical rod 46 moves with the conductive head 41 inserted between the second wire 38 and the third wire 39. Since the arc-shaped conductive sheet 40 has a certain elasticity, the arc-shaped conductive sheets 40 on both sides will clamp the conductive head 41, so that the arc-shaped conductive sheet 40 and the conductive head 41 can be in close contact and then energized. The vertical rod 46 will also move with the heat conductive sheet 42, so that the heat conductive sheet 42 is in close contact with the second wire 38 and the third wire 39. When the socket works for too long or does not work properly, causing the current flowing through the wire to suddenly increase, the wire will heat up, which will accelerate the aging of the wire and damage the device.The heat generated by the second wire 38 and the third wire 39 is transferred to the double-layer metal sheet 45 through the heat conductive sheet 42. The materials of the active layer of the double-layer metal sheet 45 mainly include manganese-nickel-copper alloy, nickel-chromium-iron alloy, nickel-manganese-iron alloy and nickel, and the material of the passive layer is mainly nickel-iron alloy with a nickel content of 30-45%. The active layer expansion coefficient of the double-layer metal sheet 45 is relatively high, and the passive layer expansion coefficient is relatively low. Since the expansion coefficients between the two layers are not uniform, the double-layer metal sheet 45 is deformed. Because the second wire 38 and the third wire 39 are rigid materials, under the reaction force of the second wire 38 and the third wire 39, the double-layer metal sheet 45 bends downward and drives the vertical rod 46 to move, so that the conductive head 41 is separated from the arc-shaped conductive sheets 40 on both sides, thereby achieving the purpose of disconnecting the circuit and protecting the device. AlN ceramic aluminum nitride is a covalent bond compound and is a ceramic material with excellent comprehensive properties. Its thermal conductivity is 8 to 10 times that of Al2O3, and its price is much lower than that of cubic boron nitride. The required sintering aid does not have the toxicity of beryllium oxide (BeO). Due to a series of excellent properties such as high thermal conductivity, extremely strong heat resistance, low dielectric constant and loss, and linear expansion coefficient matching Si, AlN is regarded as the most promising new generation of excellent insulating heat dissipation substrate material. When the socket leaks electricity, the socket leakage will generate strong electromagnetic induction lines. At this time, the magnetorheological fluid inside the liquid box 47 will change from liquid to solid, the rotating rod 17 will not be able to rotate, and the plug will not be able to be inserted into the socket 3.
