Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example: A sealed leakage protection plug, see Figures 1-4 、 Figure 8-Figure 9 As shown, it includes an upper cover 1, a bottom cover 2, a bolt 201, a circuit board 3, a power cord 4, a start button 13, a sliding rod 14, a start component, a plug 20, a leakage test button 9 and a leakage test component. The upper cover 1 and the bottom cover 2 are both made of injection molding of insulating material. The upper cover 1 and the bottom cover 2 are connected by four bolts 201. A circuit board 3 is installed in the middle of the upper cover 1. A power cord 4 electrically connected to the circuit board 3 is provided between the right side of the upper cover 1 and the bottom cover 2. A start button 13 is slidingly provided on the upper cover 1. The bottom of the start button 13 is fixedly connected to the sliding rod 14 by welding. Two plugs 20 are passed through the bottom cover 2. A start component for connecting the plug 20 circuit is provided between the circuit board 3 and the bottom cover 2. A leakage test button 9 is slidingly provided in the middle of the upper cover 1. A leakage test component for disconnecting the plug 20 circuit is provided between the leakage test button 9 and the circuit board 3. It also includes a sealing cover 5, silicone 9 and the start button 13. A silicone sheet 6 and a fault indicator light 8 are installed on the inner side of the upper cover 1. A ring boss is provided on the start button 13. An annular groove is provided at the connection between the silicone sheet 6 and the button 13. The silicone sheet 6 is sleeved with the annular boss of the start button 13 through the annular groove to achieve sealing between the silicone sheet 6 and the start button 13, and the silicone sheet 6 is in contact with the bottom of the leakage test button 9. A sealing cover plate 5 for pressing the silicone sheet 6 is installed on the side of the silicone sheet 6 close to the circuit board 3. The silicone sheet 6 is pressed by the sealing cover plate 5 to form a seal between the upper cover 1 and the leakage test button 9 and the start button 13 to prevent moisture from entering the plug through the gap between the upper cover 1 and the leakage test button 9 and the start button 13, thereby achieving the purpose of waterproofing the plug. A fault indicator light 8 for displaying the status of the plug is installed on the circuit board 3. When the fault indicator light 8 continues to flash when the plug is powered off, it indicates that the self-test has failed. The fault indicator light 8 passes through the silicone sheet 6 and the upper cover 1.

[0032] See Figure 7 As shown, the leakage test assembly includes a metal sheet 11 and a first elastic member 12. A sliding groove 10 is provided on the sealing cover plate 5. The metal sheet 11 is slidingly provided in the sliding groove 10. The metal sheet 11 is located below the leakage test button 9. The leakage test button 9 slides downward to contact the circuit board 3 by squeezing the metal sheet 11 through the silicone sheet 6. The first elastic member 12 is connected between the metal sheet 11 and the sliding groove 10.

[0033] See Figure 1 、 Figure 8 and Figure 9 As shown, a rubber sleeve 7 is also included. The rubber sleeve 7 is provided on the silicone sheet 6. The rubber sleeve 7 wraps the fault indicator light 8. The rubber sleeve 7 is provided between the fault indicator light 8 and the upper cover 1, so that the rubber sleeve 7 fills the gap between the fault indicator light 8 and the upper cover 1 to achieve the purpose of waterproof sealing.

[0034] See Figure 4 As shown, a guide rod 23 is also included. A guide rod 23 is provided on both sides of the sliding rod 14. Two sliding grooves 10 corresponding to the guide rods 23 are provided on the circuit board 3. The guide rod 23 slides up and down along the sliding groove 10. When the sliding rod 14 slides, it is guided by the guide rod 23 and the sliding groove 10 to ensure that the sliding rod 14 always goes straight up and down, and prevents the sliding rod 14 from moving out of position when moving up and down.

[0035] See Figure 10-12 As shown, an annular silicone sleeve 25 is also included. The silicone sheet 6 is provided with an annular silicone sleeve 25 for wrapping the start button 13. A groove is provided on the sealing cover plate 5. The silicone sheet 6 is located in the groove of the sealing cover plate 5. The groove of the sealing cover plate 5 wraps the annular silicone sleeve 25 of the silicone sheet 6, so that when the start button 13 is actuated, the silicone sheet 6 is deformed in the groove of the sealing cover plate 5 through the annular silicone sleeve 25, so that the silicone sheet 6 cooperates with the action of the start button 13. At the same time, the outer wall of the annular silicone sleeve 25 is tightly attached to the inner wall of the groove of the sealing cover plate 5, thereby achieving a sealing effect.

[0036] In order to prevent the start button 13 from being pushed down excessively, causing the deformation of the annular silicone sleeve 25 to exceed the tolerable range and cause damage, the sealing cover 5 is provided with a recessed cavity at the position of the start button 6 for accommodating the start button 6, and a limit block 26 is provided in the cavity for limiting the movable range of the annular silicone sleeve 25. The bottom surface of the annular silicone sleeve 25 is provided with a protrusion 27 abutting against the limit block 26. When the protrusion 27 abuts against the limit block 26, the start button 13 can be limited from being further pressed.

[0037] See Figure 5 and Figure 6 As shown, a contact piece is provided at one end of the plug 20 located on the upper part of the bottom cover 2. The plug 20 is electrically connected to the circuit board 3 through the contact piece and the starting component. The starting component controls the plug 20 to repeatedly connect the circuit with the circuit board 3 to avoid excessive wear of the plug 20.

[0038] See Figure 2-Figure 9 As shown, the structures and working principles of other components are prior art or similar to prior art, and may be slightly different in naming. They are not technical points to be improved by this solution. The following is a brief description of the functions, relative positions and working principles of the remaining components of this solution in the sealed leakage protection plug:

[0039] The starting assembly includes: a second elastic member 1401, a guide seat 15, a sliding plate 16, a third elastic member 17, a metal paddle 18, a push rod 19, an electromagnetic seat 21 and a pull rod 22. Two metal paddles 18 are connected to the side of the circuit board 3 close to the bottom cover 2. The second elastic member 1401 is sleeved on the sliding rod 14. The two ends of the second elastic member 1401 are respectively connected to the sliding rod 14 and the circuit board 3. A guide seat 15 is slidingly provided in the middle of the bottom cover 2. The guide seat 15 is located between the two inserts 20, and the sliding rod 14 passes through the guide seat 15. Both sides of the guide seat 15 are fixed. It is connected to a push rod 19, which slides upward to squeeze the two metal picks 18 to deform and contact the plug-in piece 20, thereby connecting the circuit between the plug-in piece 20 and the circuit board 3. A sliding plate 16 is provided in a horizontal sliding manner in the guide seat 15. A card slot is provided at the lower end of the sliding rod 14. The sliding rod 14 slides so that the card slot at the lower end is engaged with the sliding plate 16. A third elastic member 17 is connected between the sliding plate 16 and the guide seat 15. An electromagnetic seat 21 is installed on the side of the circuit board 3 close to the bottom cover 2. A pull rod 22 is slidably provided in the electromagnetic seat 21, and the pull rod 22 is engaged with the sliding plate 16.

[0040] When the plug needs to be used, the start button 13 is pressed down when the plug is activated. The start button 13 drives the sliding rod 14 to slide downward, and the sliding rod 14 squeezes the second elastic member 1401 to deform. The start sliding rod 14 slides downward to squeeze the sliding plate 16 to move to the right, and the sliding plate 16 compresses the third elastic member 17 to deform. When the slot on the start sliding rod 14 passes the sliding plate 16, the third elastic member 17 returns to its original state and drives the sliding plate 16 to engage with the slot 601. Then release the start button 13, and the second elastic member 1401 returns to its original state and drives the sliding rod 14 to slide upward an end distance. The start sliding rod 14 drives the guide seat 15 and the push rod 19 to slide upward through the sliding plate 16. At this time, the push rod 19 drives the metal paddle 18 to bend upward and contact the plug 20, thereby connecting the circuit between the plug 20 and the circuit board 3. When the circuit between the plug 20 and the circuit board 3 needs to be disconnected, press down. 14. The breaker body 10 is a circuit breaker body 11, which is a circuit breaker body 12.
