Description

Technical Field

[0001] This invention relates to the field of power socket technology, and more particularly to an intelligent safety socket. Background Technology

[0002] A socket is a connector for inserting one or more electrical wires, facilitating connection to other circuits. The connection and disconnection of the circuit are achieved through the connection and disconnection of the wires and copper components.

[0003] Currently, sockets commonly have a power button that controls whether the socket is powered on or off. However, during use, if the socket experiences a leakage or short circuit, it cannot activate its self-protection mechanism to disconnect, which can easily lead to the socket or the appliances connected to it burning out; and it also poses a safety hazard to the user. Summary of the Invention

[0004] The main objective of this invention is to provide an intelligent safety socket that addresses the problem of sockets failing to have a self-protection mechanism to disconnect, which can easily burn out the socket or the electrical appliances connected to it, posing a safety hazard.

[0005] To achieve the above objectives, the present invention proposes an intelligent safety socket, comprising a housing, a connecting copper plate, a current connection port, conductive contacts, a mechanical switch assembly, and an overcurrent protector. The housing has an accommodating space, and a base plate is disposed within the housing, dividing the accommodating space into a first accommodating cavity and a second accommodating cavity. The conductive copper plate is disposed within the first accommodating cavity, and includes a first electrode and a second electrode. The current connection port is fixed to the base plate and disposed within the second accommodating cavity, and includes an input port and an output port, with the output port electrically connected to the first electrode. The conductive contacts are fixedly connected to the base plate and disposed within the second accommodating cavity. Inside the cavity, the conductive contact is electrically connected to the input port; the mechanical switch assembly includes a hinge transmission mechanism and a conductive connector disposed within the second accommodating cavity, the hinge transmission mechanism being rotatably connected to the base plate, and the conductive connector being electrically connected to the second electrode; the hinge transmission mechanism can push the conductive connector to swing so that the conductive connector contacts or separates from the conductive contact; the overcurrent protector includes a first drive coil and a first drive rod, in the state where the conductive connector contacts and the conductive contact is in contact and conducting, the first drive coil is used to drive the first drive rod to move in a direction close to the conductive connector when there is an overcurrent, so as to push the conductive connector to separate from the conductive contact.

[0006] Optionally, the mechanical switch assembly further includes a button assembly and a locking assembly. The button assembly includes a connected switch button and a switch control lever. The switch button is exposed in the housing. The switch control lever is drively connected to the hinge transmission mechanism. The switch button is used to push the switch control lever to rotate, thereby causing the hinge transmission mechanism to swing. The locking assembly is used to lock the hinge transmission mechanism when the conductive connector makes contact with the conductive contact.

[0007] Optionally, the hinge transmission mechanism includes a rotary drive component, a rotary transmission component, a connecting rod, and a rotary follower component. The rotary drive component is rotatably connected to the base plate and has an input arm and a transmission arm. The switch control rod passes through the base plate and is connected to the input arm. The rotary transmission component is rotatably connected to the base plate. The two ends of the connecting rod are rotatably connected to the transmission arm and the rotary follower component, respectively. The rotary follower component is rotatably connected to the base plate, with one end rotatably connected to the rotary transmission component and the other end fixedly connected to the conductive connector.

[0008] Optionally, the locking assembly includes a first limiting member and a second limiting member; the second limiting member is rotatably connected to the base plate, the second limiting member has a first end and a second end, the first limiting member has a first slot facing the first end, the rotary transmission member has a limiting section, the limiting section has a second slot facing the second end; when the conductive connector moves toward the conductive contact, the second end is engaged in the second slot, and the rotary transmission member rotates to push the second limiting member to rotate so that the first end is engaged in the first slot.

[0009] Optionally, the smart safety socket further includes an electronic switch assembly, which includes a second drive coil and a second drive rod. The second drive coil is used to drive the second drive rod to move toward the rotary drive member.

[0010] Optionally, the smart safety socket further includes a reset member and a limiting post. The two ends of the reset member are respectively connected to the base plate and the conductive connector. The limiting post is disposed on the base plate. The reset member is used to drive the conductive connector to swing until it abuts against the limiting post.

[0011] Optionally, the smart safety socket further includes an arc extinguisher disposed within the second accommodating cavity and connected between the conductive contact and the input port.

[0012] Optionally, the smart safety socket further includes a third electrode and a grounding port. The third electrode is disposed in the first accommodating cavity, and the grounding port is disposed in the second accommodating cavity. The third electrode is electrically connected to the grounding port.

[0013] Optionally, the housing includes a middle frame, a front panel, and a back shell. The front panel and the back shell are disposed on opposite sides of the middle frame to form the accommodating space. The bottom plate is disposed between the front panel and the back shell. The front panel has insertion holes corresponding to the connecting copper plates.

[0014] Optionally, the current connection port includes a receiving frame and a wire clamping fastener threadedly connected to the receiving frame. The back cover has a connection hole and an operating hole. The connection hole is positioned opposite the receiving frame of the current connection port, and the operating hole is positioned opposite the wire clamping fastener.

[0015] In this invention, a base plate serves as the mounting substrate for each mechanism, dividing the accommodating space into a first accommodating cavity and a second accommodating cavity. The aforementioned mechanical switch assembly, overcurrent protector, conductive contacts, and current wiring ports are respectively mounted on the base plate. Through holes are provided on the housing corresponding to the current wiring ports for connection to external electrical wires. The hinge transmission mechanism can rotate, thereby causing the conductive connector to contact or separate from the conductive contacts. When the conductive connector is connected to the conductive contacts, the second electrode is connected to the input port, forming a circuit in the intelligent safety socket to supply power to external electrical appliances; conversely, the circuit is cut off, and power supply to external electrical appliances is stopped. When an overcurrent occurs, the first drive coil is energized to generate an electromagnetic field. Under the action of the electromagnetic field, the first drive rod moves to the right, pushing the conductive connector to separate from the conductive contacts, thereby cutting off the conductive circuit. This application enables an overcurrent protector to automatically disconnect the conductive connector from the conductive contacts when a leakage or short circuit occurs in the socket, thus achieving a self-protection mechanism; preventing the socket or the electrical appliances connected to the socket from burning out and improving safety performance.

[0032] A socket is a connector for inserting one or more electrical wires, facilitating connection to other circuits. The connection and disconnection of the circuit are achieved through the connection and disconnection of the wires and copper components.

[0033] Currently, sockets commonly have a power button that controls whether the socket is powered on or off. However, during use, if the socket experiences a leakage or short circuit, it cannot activate its self-protection mechanism to disconnect, which can easily lead to the socket or the appliances connected to it burning out; and it also poses a safety hazard to the user.

[0034] This invention proposes an intelligent safety socket, which aims to solve the problem that sockets cannot disconnect due to their own protection mechanism, which can easily burn out the socket or the electrical appliances connected to it, posing a safety hazard.

[0035] like Figures 1 to 5As shown, in one embodiment of the present invention, the intelligent safety socket 100 includes a housing 1, a connecting copper sheet 2, a current connection port 3, a conductive contact 4, a mechanical switch assembly 5, and an overcurrent protector 6. The housing 1 has an accommodating space, and a base plate 13 is provided inside the housing 1, which divides the accommodating space into a first accommodating cavity 11 and a second accommodating cavity 12. The conductive copper sheet is disposed in the first accommodating cavity 11, and the conductive copper sheet includes a first electrode 21 and a second electrode 22. The current connection port 3 is fixed to the base plate 13 and disposed in the second accommodating cavity 12, and the current connection port 3 includes an input port 31 and an output port 32, with the output port 32 electrically connected to the first electrode 21. The conductive contact 4 is fixedly connected to the base plate 13 and disposed in the second accommodating cavity 12. Inside the second cavity 12, the conductive contact 4 is electrically connected to the input port 31; the mechanical switch assembly 5 includes a hinge transmission mechanism 51 and a conductive connector 52 disposed in the second accommodating cavity 12. The hinge transmission mechanism 51 is rotatably connected to the base plate 13, and the conductive connector 52 is electrically connected to the second pole piece 22; the hinge transmission mechanism 51 can push the conductive connector 52 to swing so that the conductive connector 52 contacts and conducts with the conductive contact 4 or separates from it; the overcurrent protector 6 includes a first drive coil 61 and a first drive rod 62. When the conductive connector 52 is in contact with the conductive contact 4 and conducts, the first drive coil 61 is used to drive the first drive rod 62 to move in the direction close to the conductive connector 52 when there is an overcurrent, so as to push the conductive connector 52 to separate from the conductive contact 4.

[0036] In this embodiment, the base plate 13 serves as the mounting base for each mechanism, and the base plate 13 divides the accommodating space into two parts: a first accommodating cavity 11 and a second accommodating cavity 12. The aforementioned mechanical switch assembly 5, overcurrent protector 6, conductive contact 4, and current wiring port 3 are respectively mounted on the base plate 13. A through hole is provided on the housing 1 at the position corresponding to the current wiring port 3 to allow the current wiring port 3 to connect to an external wire. The hinge transmission mechanism 51 can rotate, thereby driving the conductive connector 52 to contact or separate from the conductive contact 4. When the conductive connector 52 is connected to the conductive contact 4, the second pole piece 22 is connected to the input port 31, and the intelligent safety socket 100 forms a circuit to supply power to external electrical appliances; conversely, the circuit is cut off and the power supply to external electrical appliances is stopped. When an overcurrent occurs, the first drive coil 61 is energized to generate an electromagnetic field. Under the action of the electromagnetic field, the first drive rod 62 is driven to move to the right. The first drive rod 62 pushes the conductive connector 52 to separate from the conductive contact 4, thereby cutting off the conductive circuit. This application enables the overcurrent protector 6 to automatically disconnect the conductive connector 52 from the conductive contact 4 when the smart safety socket 100 experiences leakage or short circuit, thus achieving a self-protection mechanism; preventing the smart safety socket 100 or the electrical appliances connected to the smart safety socket 100 from burning out, and improving safety performance.

[0037] The current connection port 3 includes an input port 31 and an output port 32. In AC applications, the input port 31 is connected to the live (L) wire, and the output port 32 is connected to the neutral (N) wire. In DC applications, the input port 31 is connected to the positive (+) terminal, and the output port 32 is connected to the negative (-) terminal. The connecting copper plate 2 includes a first electrode 21 and a second electrode 22. The output port 32 is connected to the first electrode 21, while the input port 31 is connected to the conductive contact 4. The second electrode 22 is connected to the mechanical switch assembly 5. The mechanical switch assembly 5 can selectively contact or disconnect from the conductive contact 4. When the mechanical switch assembly 5 is connected to the conductive contact 4, the second electrode 22 is connected to the input port 31, thus forming a circuit to supply power to external electrical appliances. Conversely, when the mechanical switch assembly 5 is disconnected, the circuit is cut off, and power supply to external electrical appliances is stopped.

[0038] In some embodiments, the smart safety socket 100 further includes a grounding port 33 mounted on the base plate 13 and located within the second accommodating cavity 12, and a third pole piece 23 is used to connect to the grounding port 33 to achieve grounding (GND). That is, in this application, there may be only two pole pieces (first pole piece 21 and second pole piece 22), which are fixed on the base plate 13 according to the standard two-hole socket position; or there may be three pole pieces (first pole piece 21, second pole piece 22 and third pole piece 23), which are fixed on the base plate 13 according to the standard three-hole socket position. The number of pole pieces is consistent with the number of ports (input port 31, output port 32, and grounding port 33) and is set in a one-to-one correspondence. The pole pieces are used to connect to the plug of external electrical appliances, and the ports are used to connect to the power supply line.

[0039] Based on the above embodiments, the mechanical switch assembly 5 further includes a button assembly 53 and a locking assembly 54. The button assembly 53 includes a switch button 531 and a switch control lever 532 connected to each other. The switch button 531 is exposed in the housing 1. The switch control lever 532 is connected to the hinge transmission mechanism 51. The switch button 531 is used to push the switch control lever 532 to rotate so as to drive the hinge transmission mechanism 51 to swing. The locking assembly 54 is used to lock the hinge transmission mechanism 51 when the conductive connector 52 contacts the conductive contact 4 to conduct electricity.

[0040] Normally, the switch button 531 has two positions: on and off. When the switch button 531 is in the on position, its movement drives the hinge transmission mechanism 51 via the switch control lever 532. Simultaneously, the hinge transmission mechanism 51 drives the conductive connector 52 to approach the conductive contact 4 until the conductive connector 52 contacts the conductive contact 4, thereby connecting the second electrode 22 to the input port 31 and thus establishing a conductive circuit. When the switch button 531 is in the off position, its movement drives the hinge transmission mechanism 51 via the switch control lever 532. Simultaneously, the hinge transmission mechanism 51 drives the conductive connector 52 to separate from the conductive contact 4, thereby disconnecting the second electrode 22 from the input port 31 and thus cutting off the conductive circuit.

[0041] Specifically, the hinge transmission mechanism 51 includes a rotary drive member 511, a rotary transmission member 512, a connecting rod 513, and a rotary follower member 514. The rotary drive member 511 is rotatably connected to the base plate 13 and has an input arm 5111 and a transmission arm 5112. The switch control rod 532 passes through the base plate 13 and is connected to the input arm 5111. The rotary transmission member 512 is rotatably connected to the base plate 13. The two ends of the connecting rod 513 are rotatably connected to the transmission arm 5112 and the rotary follower member 514, respectively. The rotary follower member 514 is rotatably connected to the base plate 13. One end of the rotary follower member 514 is rotatably connected to the rotary transmission member 512, and the other end is fixedly connected to the conductive connector 52.

[0042] The rotary drive component 511 is rotatably hinged to the base plate 13. A limiting guide groove is provided on the base plate 13. The switch control rod 532 passes through the limiting guide groove and is connected to the rotary drive component 511. The limiting guide groove can limit the movement trajectory and stroke of the switch control rod 532. The rotary drive component 511 is also hinged to the rotary transmission component 512 via the connecting rod 513 (hinge position: hinge point one); the rotary transmission component 512 is hinged to the rotary follower component 514 (hinge position: hinge point two), and the rotary transmission component 512 and the rotary follower component 514 are rotatably hinged to the base plate 13 (hinge position: hinge point three); and the rotary follower component 514 is connected to the conductive connector 52.

[0043] When using the switch button 531 for control, when the user turns the switch button 531 from the off position to the on position, the switch button 531 drives the control lever to move upward in the limit guide groove to the top of the limit guide groove;

[0044] The upward-moving control lever drives the rotary drive 511 to rotate forward around its hinge point. The rotary drive 511 drives the connecting rod 513 and its connected end to move downward. Conversely, the other end of the connecting rod 513 moves upward, thereby driving the transmission end (upper half of the rotary transmission 512) of the rotary transmission 512 to move upward.

[0045] The upward-moving transmission segment drives the rotating follower 514 to rotate in the forward direction around its hinge point 3, thereby causing the conductive connector 52 to move downward to the position of contacting the conductive contact 4, thus realizing the conduction of the intelligent safety socket 100, and the locking component 54 locks the hinge transmission mechanism 51 to keep the intelligent safety socket 100 conducting.

[0046] Conversely, when the user turns the switch button 531 from the ON position to the OFF position, the movement trajectory of the hinge transmission mechanism 51 is opposite to that described above, and it can release the lock, causing the conductive connector 52 to separate from the conductive contact 4, thereby disconnecting the smart safety socket 100.

[0047] In one embodiment, please refer to [reference needed]. Figure 6 The locking assembly 54 includes a first limiting member 541 and a second limiting member 542. The second limiting member 542 is rotatably connected to the base plate 13. The second limiting member 542 has a first end 5421 and a second end 5422. The first limiting member 541 has a first slot 5411 that is directly opposite to the first end 5421. The rotary transmission member 512 has a limiting section 5141. The limiting section 5141 has a second slot 5142 that is directly opposite to the second end 5422. When the conductive connector 52 moves toward the conductive contact 4, the second end 5422 is inserted into the second slot 5142, and the rotary transmission member 512 rotates to push the second limiting member 542 to rotate so that the first end 5421 is inserted into the first slot 5411.

[0048] When the user turns the switch button 531 from the off position to the on position, the upward-moving transmission section also drives the limiting section 5141 to rotate forward around its hinge point, causing the limiting second slot 5142 to move upward as a whole, so that the second end 5422 of the second limiting member 542 enters the limiting second slot 5142. At this time, the limiting section 5141 abuts against the second end 5422. As the limiting second slot 5142 continues to move upward, the limiting section 5141 can cause the second limiting member 542 to rotate in the opposite direction around its hinge point through the second end 5422 that abuts against it. At the same time, the spring of the second limiting member 542 is compressed, and the spring has elastic potential energy that causes the second limiting member 542 to rotate in the opposite direction.

[0049] A spring is provided on the first limiting member 541. When the second limiting member 542 rotates in the opposite direction, the first end 5421 of the second limiting member 542 enters the limiting slot and abuts against the upper end of the first limiting member 541. As the second limiting member 542 rotates continuously, the first end 5421 pushes the upper end of the first limiting member 541 to move upward, so that the first limiting member 541 rotates in the opposite direction around its hinge point. This causes the spring on the first limiting member 541 to be compressed, thus having elastic potential energy for positive rotation. Under the interaction of the elastic forces of the two, the elastic potential energy of the second limiting member 542 rotating in the opposite direction cancels out the elastic potential energy of the first limiting member 541 rotating in the positive direction, so that the rotation of both the first limiting member 541 and the second limiting member 542 is stopped, thereby realizing the stopping function of the hinge transmission mechanism 51, and thus keeping the smart safety socket 100 in a conductive state.

[0050] In one embodiment, the smart safety socket 100 further includes an electronic switch assembly 7, which includes a second drive coil 71 and a second drive rod 72. The second drive coil 71 drives the second drive rod 72 to move towards the rotary drive member 511. The electronic switch assembly 7 is communicatively connected to an external control terminal. When the electronic switch assembly 7 receives a control command, the second drive coil 71 generates an electromagnetic field. Under the action of the electromagnetic field, the second drive rod 72 is driven to rotate towards the hinge transmission mechanism 51. The hinge transmission mechanism simultaneously drives the conductive connector 52, the transmission rod, and the switch button 531 to move, thereby changing the contact or separation state between the conductive connector 52 and the conductive contact 4. By setting an electronic switch, the on / off control methods of the smart safety socket 100 are enriched, realizing the joint control function of electronic and mechanical control, which is beneficial to ensuring the reliability of on / off control.

[0051] Based on the above embodiments, the electronic switch assembly 7 is connected to an external switch control board. The switch control board generates control commands under the user's control instructions and inputs current to the second drive coil 71 under the control commands, thereby generating an electromagnetic field. Under the action of the electromagnetic field, the second drive rod 72 is driven to push the hinge transmission mechanism 51 to rotate.

[0052] In a preferred embodiment, with the electronic switch provided, the switch control board can communicate with external devices (such as wireless communication, PLC communication, etc.), and users can send control commands to the smart safety socket 100 through mobile phones or other terminal devices, so that the smart safety socket 100 has the function of remote control on / off.

[0053] Optionally, the smart safety socket 100 also includes a reset member 81 and a limiting post 82. The two ends of the reset member 81 are connected to the base plate 13 and the conductive connector 52, respectively. The limiting post 82 is disposed on the base plate 13. The reset member 81 is used to drive the conductive connector 52 to swing until it abuts against the limiting post. The reset member 81 can be a tension spring. When the user turns the switch button 531 from the off position to the on position, the tension spring is stretched as the conductive connector 52 moves downward, giving it elastic potential energy to pull the conductive connector 52 back to its initial position. When the user turns the switch button 531 from the on position to the off position, the locking component 54 unlocks, and the tension spring provides auxiliary driving force for the conductive connector 52 to disengage from the conductive contact 4. A limiting post 82 can also be provided on the base plate 13, allowing the conductive connector 52 to return to the position abutting against the limiting post 82 under the action of the tension spring.

[0054] Specifically, when the user turns the switch button 531 from the off position to the on position, the switch button 531 drives the control lever to move downward in the limit guide groove to the bottom of the limit guide groove;

[0055] The upward-moving control lever drives the rotary drive 511 to rotate in the opposite direction around its hinge point. The rotary drive 511 drives the end of the connecting rod 513 connected to it to move upward. Conversely, the other end of the connecting rod 513 moves downward, thereby driving the transmission section of the rotary transmission component to move downward.

[0056] The downward-moving transmission segment drives the rotating follower 514 to rotate in the opposite direction around its hinge point three, thereby causing the conductive connector 52 to move upward and separate from the conductive contact 4, thus disconnecting the smart safety socket 100. Under the elastic potential energy of the tension spring, the conductive connector 52 is pulled back to its initial position. Simultaneously, the downward-moving transmission segment also drives the limiting segment 5141 to rotate in the opposite direction around its hinge point three, causing the limiting slot two to move downward as a whole, so that the second end 5422 of the second limiting member 542 gradually engages with the limiting slot two. During the separation, as the limiting segment 5141 moves downward, it pushes the second end 5422 downward. Under the elastic potential energy of the spring on the second limiting member 542 rotating in the opposite direction, the second limiting member 542 rotates in the opposite direction around its hinge point until the second end 5422 moves outside the second limiting slot and separates from the limiting segment 5141. During the reverse rotation of the second limiting member 542, the first end 5421 moves upward outside the first limiting slot and separates from the upper end of the first limiting member 541. When the second limiting member 542 is outside both the first and second limiting slots, under the elastic potential energy of the spring on it rotating in the opposite direction, the second limiting member 542 rotates in the opposite direction and springs back to the position where the spring is not compressed.

[0057] After the upper end of the first limiting member 541 separates from the first end 5421 of the second limiting member 542, under the action of the elastic potential energy of the spring's forward rotation, the first limiting member 541 rotates forward and rebounds to the position where the spring is not compressed.

[0058] If an overcurrent occurs, the first drive coil 61 of the overcurrent protector 6 is charged, causing the first drive rod 62 to push the conductive connector 52 to the right and upward, separating the conductive connector 52 from the conductive contact 4. The conductive connector 52 then drives the hinge transmission assembly to move, which in turn drives the switch control rod 532 to move downward within the limit guide groove, causing the switch button 531 to switch back from the ON position to the OFF position. Throughout this process, the movement principle of the hinge transmission assembly is consistent with the movement principle of the hinge transmission assembly when the switch button 531 switches from the OFF position to the ON position, and will not be described further here.

[0059] When controlled by electronic switch assembly 7:

[0060] When the smart safety socket 100 is in the off state, the rotary drive 511 is located on the travel path of the drive rod of the electronic switch assembly 7.

[0061] When the electronic switch assembly 7 receives the on control command, it charges the driving electromagnet. Under the drive of electromagnetic force, the driving rod moves to the left to extend outside the electronic switch assembly 7, and the driving rod pushes the rotary driving member 511 to rotate in the forward direction. The forward rotating rotary driving member 511 drives the switch control rod 532 to rotate and move upward in the limit guide groove, so that after the switch button 531 is turned from the off position to the on position, the charging of the driving electromagnet stops, and the driving rod returns to the electronic switch assembly 7 under the action of magnetic force. At the same time, the driving of other components of the hinge transmission mechanism 51 by the forward rotating rotary driving member 511 is basically the same as the above principle, and will not be described again here.

[0062] When the smart safety socket 100 is in the conducting state, the upper end of the first limiting member 541 is located on the travel path of the drive rod of the electronic switch assembly 7.

[0063] When the electronic switch assembly 7 receives the off control command, it drives the electromagnet to charge. Under the drive of the electromagnetic force, the drive rod moves to the left to extend out of the electronic switch assembly 7, and the drive rod pushes the upper end of the first limiting member 541 to move to the left, so that the first end 5421 of the second limiting member 542 leaves the limiting slot 1, thereby releasing the first end 5421 of the second limiting member 542.

[0064] After the first end 5421 is released, under the action of the elastic potential energy of the spring of the second limiting member 542 rotating in the forward direction, the second end 5422 of the second limiting member 542 pushes the limiting segment 5141 to rotate in the opposite direction around its hinge point, so that the second end 5422 separates from the limiting segment 5141; at the same time, charging of the driving electromagnet stops, so that the driving rod returns to the electronic switch assembly 7 under the action of magnetic force.

[0065] In addition, the reverse-rotating limiting segment 5141 drives the transmission segment to move downward, which in turn causes the transmission segment to drive the rotating follower 514 to rotate in the opposite direction, thereby causing the conductive connector 52 to separate from the conductive contact 4, thus realizing the disconnection of the smart safety socket 100; after the limiting segment 5141 separates from the second end 5422, under the action of the elastic potential energy of the tension spring, the conductive connector 52 is pulled back to the initial position (for example, a limiting post 82 is set, and the conductive connector 52 returns to the position where it abuts against the limiting post 82).

[0066] Under the action of the tension spring, the conductive connector 52 moves upward, thereby driving the rotary follower 514 and the rotary transmission member 512 to rotate in the opposite direction. During the reverse rotation, the rotary transmission member 512 simultaneously drives the rotary drive member 511 to rotate in the opposite direction through the transmission rod.

[0067] The reverse-rotating drive 511 causes the switch control lever 532 to move upward in the limit guide groove, thereby causing the switch button 531 to switch from the off position to the on position.

[0068] Optionally, the smart safety socket 100 also includes an arc extinguisher 9, which is disposed within the second receiving cavity 12 and connected between the conductive contact 4 and the input port 31. The arc extinguisher 9 is used to eliminate the electric arc phenomenon generated during the operation of the smart safety socket 100, which helps to ensure the safety of the smart safety socket 100 and improve its service life. It also protects electrical appliances from the effects of electric arcs during the use of the smart safety socket 100.

[0069] Specifically, the housing 1 includes a middle frame 14, a front panel 15, and a back shell 16. The front panel 15 and the back shell 16 cover the opposite sides of the middle frame 14 to form an accommodating space. A bottom plate 13 is disposed between the front panel 15 and the back shell 16. The front panel 15 has a socket 171 corresponding to the connecting copper plate 2. The connecting copper plate 2 is located in the first accommodating cavity 11 and is mounted on the middle frame 14. The front panel 15 has a socket 171 at the position corresponding to the connecting copper plate 2. The plug of an external electrical appliance is inserted into the connecting copper plate 2 through the socket 171. A switch button 531 is disposed on the front panel 15. The switch button 531 can swing up and down, thereby driving the switch control lever 532 to push the rotary drive member 511 to rotate clockwise or counterclockwise.

[0070] Specifically, the current connection port 3 includes a receiving frame 341 and a wire clamping fastener 342 threadedly connected to the receiving frame 341. A wiring hole 1172 and an operating hole 173 are provided on the back cover 16. The wiring hole 1172 is positioned opposite the receiving frame 341 of the current connection port 3, and the operating hole 173 is positioned opposite the wire clamping fastener 342. The back cover 16 includes a base plate 13 and a cover plate. By providing the wiring hole 1172 on the base plate 13, the power cord can pass through the wiring hole 1172 and be inserted into the receiving frame 341. The user can use a tool to rotate the wire clamping fastener 342 through the operating hole 173, clamping and fixing the power cord between the wire clamping fastener 342 and the inner wall of the receiving frame 341, preventing the power cord from loosening. Furthermore, by providing the wiring hole 1172 and the operating hole 173 on the back cover 16, it is not necessary to disassemble the smart safety socket 100 during wiring operations.
