An electric shock protection socket

Abstract

This application relates to an anti-electric shock socket, including a socket body and a panel. The panel has two socket holes, and the socket body has two metal clips. It also includes a vacuum assembly, a detection and control assembly, and two suction cups. The two suction cups are respectively disposed in the two socket holes. When a plug is inserted into a metal clip, the inner wall of the rear end of the suction cup adheres to the outer wall of the plug pins, and the front end of the suction cup surrounds the plug pins and abuts against the outer end face of the two-prong plug. The vacuum assembly is used to remove air from the suction cups, and the detection and control assembly is used to detect the vacuum level in the suction cups and control the energization of the metal clips. When the suction cups maintain a vacuum state, the two metal clips are energized; when the suction cups deflate, the two metal clips are de-energized. If a conductive object such as a nail or hairpin touches the plug pins through the gap between the socket and the plug, the vacuum of the suction cups will inevitably fail, and the metal clips will be de-energized, thereby improving the anti-electric shock effect of the socket.

Description

Technical Field

[0001] This invention relates to the field of sockets, and in particular to a socket designed to prevent electric shock. Background Technology

[0002] With the rapid development of the national economy, people's demand for and reliance on electrical appliances are increasing, leading to a surge in the use of household sockets. Sockets allow for the insertion of wires, facilitating connection to other circuits, and are closely related to people's lives. As people's safety awareness has improved, anti-electric shock sockets have appeared on the market to prevent children from inserting their fingers or metal objects into sockets and causing electric shock.

[0003] Anti-electric shock sockets typically have mechanical safety shutters inside the socket. However, this doesn't prevent children from using conductive metal objects like nails or hairpins to directly touch the plug's prongs through the gap between the socket and the plug when it's inserted, posing a risk of electric shock. Alternatively, adding a cover or shield to the outside of the socket can achieve the same effect, but this is inconvenient to use, and children might remove the cover out of curiosity, still posing a risk of electric shock. Summary of the Invention

[0004] To improve the protection against electric shock of the socket, this application provides an electric shock breaker.

[0005] The electric shock resistant socket provided in this application adopts the following technical solution: An anti-electric shock socket includes a socket body and a panel detachably connected to the socket body. The panel has two holes for inserting a two-prong plug. The socket body has two metal clips for holding the plug prongs inserted into the holes. It also includes a vacuum assembly, a detection and control assembly, and two suction cups. The two suction cups are respectively disposed in the two holes. The rear end of the suction cup near the metal clip matches the shape of the plug and is fixedly disposed in the hole. The front end of the suction cup away from the metal clip is flared. When the plug is inserted into the metal clip, the inner wall of the rear end of the suction cup fits against the outer wall of the plug prong, and the front end of the suction cup surrounds the plug prong and abuts against the outer end face of the two-prong plug. The vacuum pumping component is mounted on the panel and is used to extract air from the suction cup. The detection and control component is used to detect the vacuum level in the suction cup and control the power supply of the metal clips. When the suction cup is in a vacuum state, the detection and control component controls the two metal clips to be powered on; when the suction cup leaks air, the detection and control component controls the two metal clips to be de-powered.

[0006] By adopting the above technical solution, after the vacuum device evacuates the inside of the suction cup, the suction cup will adhere to the outer shell end face of the two-prong plug. At this time, the metal clips can be energized. Once a conductive metal object such as an iron nail or hairpin directly touches the plug's prongs through the gap between the socket and the plug, the vacuum of the suction cup will inevitably fail. At this time, the detection and control component will control the two metal clips to cut off the power, eliminating the risk of electric shock. This improves the socket's anti-electric shock effect.

[0007] Preferably, the vacuum assembly includes a first tube, a first spring, a pressing block, a partition, a mounting bracket, a first one-way valve, a second one-way valve, and a fixing block with an inner cavity. The fixing block is mounted on the mounting bracket, and the panel has a receiving groove for accommodating the vacuum assembly. The mounting bracket is fixed to the panel by bolts. The top end of the first tube is connected to the bottom end of the inner cavity, and the bottom end of the first tube branches into two tubes that are respectively connected to the front ends of the two suction cups. The partition is fixedly installed inside the inner cavity, dividing the inner cavity into a first cavity and a second cavity. The bottom ends of the first cavity and the second cavity are interconnected. The pressing block is slidably connected in the second cavity in the vertical direction, and the top end of the pressing block extends above the panel. The two ends of the first spring are respectively fixedly installed on the bottom wall of the second cavity and on the pressing block. The top end of the first tube is connected to the bottom end of the second cavity. The first one-way valve is installed at the top end of the first tube, allowing only the gas from the first tube to enter the second cavity. A connecting port is opened through the top end of the first cavity, and the second one-way valve is installed at the connecting port, allowing only the gas in the first cavity to enter the outside.

[0008] By adopting the above technical solution, after the user inserts the plug, one hand presses the plug firmly onto the suction cup, while the other hand continuously pulls the pressing block back and forth to evacuate the inner cavity. Since the inner cavity is connected to the suction cup through the first tube, a negative pressure will be formed inside the suction cup, thus firmly adhering to the outer shell end face of the two-prong plug.

[0009] Preferably, it also includes a venting assembly, which includes a second pipe and a plug. The second pipe is fixedly mounted on the mounting bracket. The bottom end of the second pipe is connected to the first pipe, and the top end of the second pipe passes through the mounting bracket and is connected to the outside. The plug is inserted into the top end of the second pipe.

[0010] By adopting the above technical solution, when it is necessary to unplug the plug, the user applies force to pull out the plug, and the air will enter the first tube from the second tube and then enter the suction cup. The suction cup will release air, making it easier to unplug the plug.

[0011] Preferably, the live component includes two conductive bases, and the socket body has an L-shaped mounting base inside. The mounting base has two mounting slots, and two metal clips are respectively disposed in the two mounting slots. The two conductive bases are respectively fixedly disposed on the mounting base. The conductive bases are located on the side of the metal clips away from the panel and are left with a certain distance from the metal clips. The conductive bases have terminals, and the back of the socket body has two clearance slots, with the ends of the two terminals respectively located in the two clearance slots.

[0012] By adopting the above technical solution, users can connect the neutral wire and the live wire to the two terminals respectively from the outside of the socket.

[0013] Preferably, the detection and control assembly includes a piston, a connecting rod, a second spring, an insulating strip, a third tube, and two conductive blocks. A first groove is formed on the back of the panel. The third tube is disposed inside the panel, with its two ends connected to the first tube and the first groove, respectively. The piston slides in the first groove parallel to the insertion and removal direction of the plug. The second spring is located in the first groove, with its two ends fixedly disposed on the bottom wall of the first groove and on the piston, respectively. One end of the connecting rod is fixedly disposed on the piston, and the other end of the connecting rod is fixedly connected to the insulating strip. The two conductive blocks are fixedly disposed at both ends of the insulating strip and abut against two conductive seats. The conductive blocks are located on the side of the metal clips away from the panel, and the conductive blocks and conductive seats are slidably connected to each other. The two conductive blocks are respectively facing the two metal clips. When the suction cup is in a vacuum state, the conductive block moves to abut against the corresponding metal clip; when the suction cup is deflated, the conductive block moves away from the corresponding metal clip.

[0014] By adopting the above technical solution, when the suction cup maintains a vacuum state, the internal and external air pressure of the piston drives the piston towards the first tube side. The piston, through the connecting rod and insulating strip, moves the two conductive blocks towards the metal clips side, causing the two conductive blocks to contact the two metal clips respectively, energizing the two metal clips. When the suction cup deflates, the second spring drives the piston to move away from the first tube side. The piston, through the connecting rod and insulating strip, moves the two conductive blocks away from the metal clips side, causing the conductive blocks to detach from the metal clips, de-energizing the two metal clips. Since the two conductive blocks are located on the side of the metal clips away from the panel... Preferably, the metal clip has a conductive protrusion on one end face near the conductive block, and the conductive block has a groove on one side facing the conductive protrusion that matches the conductive protrusion.

[0015] By adopting the above technical solution, when the suction cup is kept in a vacuum state, the conductive block moves to abut against the corresponding metal clip. At this time, the conductive protrusion will abut against the inner wall of the groove, which can increase the contact area between the conductive block and the clip and improve the electrical conduction performance.

[0016] The main technical effects of this invention are reflected in the following aspects: 1. After the vacuum device of this invention evacuates the inside of the suction cup, the suction cup will adhere to the outer end face of the two-prong plug. At this time, the metal clips can be energized. If a conductive metal object such as an iron nail or hairpin is used to directly contact the plug prongs through the gap between the socket and the plug, the vacuum of the suction cup will inevitably fail. At this time, the detection and control component controls the two metal clips to cut off the power, eliminating the risk of electric shock. This improves the anti-electric shock effect of the socket. 2. After the plug is inserted, the user of this invention presses the plug firmly onto the suction cup with one hand and pulls the pressing block back and forth with the other hand to evacuate the inner cavity. Since the inner cavity is connected to the suction cup through the first tube, a negative pressure will be formed inside the suction cup, thus firmly adhering to the outer shell end face of the two-prong plug.

[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0026] This application discloses an anti-electric shock socket.

[0027] Reference Figure 1 and Figure 2 An anti-electric shock socket according to this embodiment includes a socket body 1 and a panel 2 detachably connected to the socket body 1. The panel 2 has two socket holes 21 for inserting a two-prong plug 6. The socket body 1 has two metal clips 11 inside, which are used to hold the plug pins 61 inserted into the socket holes 21. It also includes a vacuum assembly 3, a detection and control assembly 7 and two suction cups 5. The two suction cups 5 are respectively disposed in the two socket holes 21. The rear end of the suction cup 5 near the metal clip 11 matches the shape of the plug and is fixedly disposed in the socket hole 21. The front end of the suction cup 5 away from the metal clip 11 is flared. When the plug is inserted into the metal clip 11, the inner wall of the rear end of the suction cup 5 is attached to the outer wall of the plug pin 61, and the front end of the suction cup 5 surrounds the plug pin 61 and abuts against the outer end face of the two-prong plug 6.

[0028] Reference Figures 2-4 The vacuum assembly 3 is installed on the panel 2 and is used to extract air from the suction cup 5. The detection and control assembly 7 is used to detect the vacuum level in the suction cup 5 and control the power supply of the metal clips 11. When the suction cup 5 is in a vacuum state, the detection and control assembly 7 controls the two metal clips 11 to be powered on; when the suction cup 5 leaks air, the detection and control assembly 7 controls the two metal clips 11 to be de-powered.

[0029] Reference Figures 2-4After the vacuum device evacuates the inside of the suction cup 5, the suction cup 5 will adhere to the outer end face of the two-prong plug 6. At this time, the metal clip 11 can be energized. If a conductive metal object such as an iron nail or hairpin is used to directly contact the plug pin 61 through the gap between the socket and the plug, the vacuum of the suction cup 5 will inevitably fail. At this time, the detection and control component 7 controls the two metal clips 11 to cut off the power, so there is no risk of electric shock. This improves the anti-electric shock effect of the socket.

[0030] Reference Figures 2-4 The vacuum assembly 3 includes a first tube 31, a first spring 32, a pressing block 33, a partition 35, a mounting bracket 36, a first one-way valve 37, a second one-way valve 38, and a fixing block 39 with an inner cavity. The fixing block 39 is mounted on the mounting bracket 36. The panel 2 has a receiving groove 22 for accommodating the vacuum assembly 3. The mounting bracket 36 is fixed to the panel 2 by bolts.

[0031] Reference Figures 2-4 The top end of the first tube 31 is connected to the bottom end of the inner cavity, and the bottom end of the first tube 31 branches into two tubes that are respectively connected to the front ends of the two suction cups 5.

[0032] Reference Figures 2-4 A partition 35 is fixedly installed inside the inner cavity, dividing the inner cavity into a first cavity 391 and a second cavity 392. The bottom ends of the first cavity 391 and the second cavity 392 are connected to each other. A pressing block 33 is slidably connected in the second cavity 392 in the vertical direction. The top end of the pressing block 33 extends above the panel 2. The two ends of the first spring 32 are fixedly installed on the bottom wall of the second cavity 392 and the pressing block 33, respectively. The top end of the first tube 31 is connected to the bottom end of the second cavity 392. A first one-way valve 37 is installed at the top end of the first tube 31. The first one-way valve 37 only allows gas from the first tube 31 to enter the second cavity 392. A connecting port is opened through the top end of the first cavity 391. A second one-way valve 38 is installed at the connecting port. The second one-way valve 38 only allows gas from the first cavity 391 to enter the outside.

[0033] Reference Figures 2-4 After the user inserts the plug, one hand presses the plug firmly onto the suction cup 5, while the other hand pulls the pressing block 33 back and forth to evacuate the inner cavity. Since the inner cavity is connected to the suction cup 5 through the first tube 31, a negative pressure will be formed inside the suction cup 5, thus firmly adhering to the outer shell end face of the two-prong plug 6.

[0034] Reference Figures 2-4 It also includes a venting assembly 4, which includes a second pipe 41 and a plug 4234. The second pipe 41 is fixedly mounted on the mounting bracket 36. The bottom end of the second pipe 41 is connected to the first pipe 31, and the top end of the second pipe 41 passes through the mounting bracket 36 to communicate with the outside. The plug 4234 is inserted into the top end of the second pipe 41. The plug 4234 is provided with a pull ring 421 for manual force application.

[0035] Reference Figures 2-4 When it is necessary to unplug the plug, the user applies force to pull the plug 4234 on the pull ring 421. Air will enter the first tube 31 from the second tube 41 and then into the suction cup 5. The suction cup 5 will deflate, making it easier to unplug the plug.

[0036] Reference Figure 5 and Figure 6 The live assembly includes two conductive bases 8. The socket body 1 has an L-shaped mounting base 12 inside. The mounting base 12 has two mounting slots 121. Two metal clips 11 are respectively disposed in the two mounting slots 121. The two conductive bases 8 are respectively fixedly disposed on the mounting base 12. The conductive base 8 is located on the side of the metal clips 11 away from the panel 2 and a certain distance is left between them. The conductive base 8 has a wiring terminal 81. The back of the socket body 1 has two clearance slots 13. The ends of the two wiring terminals 81 are respectively located in the two clearance slots 13.

[0037] Reference Figure 5 and Figure 6 Users can connect the neutral wire and the live wire to the two terminals 81 from the outside of the socket body 1.

[0038] Reference Figure 4 , Figure 5 and Figure 7 The detection control component 7 includes a piston 71, a connecting rod 72, a second spring 73, an insulating strip 74, a third tube 75, and two conductive blocks 76. A first groove 23 is provided on the back of the panel 2. The third tube 75 is disposed in the panel 2, and its two ends are respectively connected to the first tube 31 and the first groove 23. The piston 71 slides in the first groove 23 parallel to the insertion and removal direction of the plug. The second spring 73 is located in the first groove 23, and its two ends are respectively fixedly disposed on the bottom wall of the first groove 23 and on the piston 71. One end of the connecting rod 72 is fixedly disposed on the piston 71, and the other end of the connecting rod 72 is fixedly connected to the insulating strip 74. The two conductive blocks 76 are respectively fixedly disposed on the two ends of the insulating strip 74. The two conductive blocks 76 abut against the two conductive seats 8, and the conductive blocks 76 and the conductive seats 8 are slidably connected to each other. The two conductive blocks 76 are respectively facing the two metal clips 11.

[0039] Reference Figure 5 When the suction cup 5 is in a vacuum state, the conductive block 76 moves to abut against the corresponding metal clip 11; when the suction cup 5 is deflated, the conductive block 76 moves away from the corresponding metal clip 11.

[0040] Reference Figures 5-7When the suction cup 5 is in a vacuum state, the internal and external air pressure of the piston 71 drives the piston 71 toward the first tube 31. The piston 71 drives the two conductive blocks 76 toward the metal clip 11 through the connecting rod 72 and the insulating strip 74, so that the two conductive blocks 76 contact the two metal clips 11 respectively, and the two metal clips 11 are energized. When the suction cup 5 is de-energized, the second spring 73 drives the piston 71 to move away from the first tube 31. The piston 71 drives the two conductive blocks 76 away from the metal clips 11 through the connecting rod 72 and the insulating strip 74, so that the conductive blocks 76 are disengaged from the metal clips 11, and the two metal clips 11 are de-energized.

[0041] Reference Figure 2 and Figure 5 The metal clip 11 has a conductive protrusion 111 on one end face near the conductive block 76, and a groove 761 matching the conductive protrusion 111 is opened on the side of the conductive block 76 opposite to the conductive protrusion 111.

[0042] Reference Figure 2 and Figure 5 When the suction cup 5 is in a vacuum state, the conductive block 76 moves to abut against the corresponding metal clip 11. At this time, the conductive protrusion 111 abuts against the inner wall of the groove 761, which can increase the contact area between the conductive block 76 and the clip and improve the electrical conduction performance.

[0043] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
