[0040] Embodiment one

[0041] Please refer to Figures 1 to 4 And Figure 7In the first embodiment of the present application, a safety socket 10 is provided, which comprises a housing 11, a protection assembly 12, a first trigger 13 and a second trigger 14. The housing 11 has an open first socket 111 for receiving a plug pin. Specifically, the housing 11 can be provided as a single socket or multiple sockets, which can be selected from, but not limited to, a combination of a two-pin socket and a three-pin socket, one of a two-pin socket and a three-pin socket, or other combinations, etc. This multifunctional design allows the safety socket 10 to adapt to different standard power plugs, increasing the flexibility of use. It can be understood that the first socket 111 is not a single "socket", but one of a two-pin socket, a three-pin socket or other types of socket. The housing 11 is internally provided with plug-in pieces 112, which are correspondingly arranged below the first socket 111. These plug-in pieces 112 will not be conductive with the power supply when there is no corresponding plug pin inserted, thereby ensuring the safety of the safety socket 10 in the unused state.

[0042] The protection assembly 12 is arranged inside the housing 11 and specifically comprises a first protection door 121 located above the plug-in pieces 112 and below the first socket 111. When the plug pin is inserted into the first socket 111, it will abut against the first protection door 121, causing the first protection door 121 to displace to allow the plug pin to smoothly enter the first socket 111 and eventually contact the plug-in pieces 112, while remaining closed (reset state) when there is no plug inserted.

[0043] The first trigger 13 is located on one side of the first protection door 121 and moves with the movement of the first protection door 121. The movement of the first trigger 13 is the main factor controlling the on-off of the plug-in pieces 112 and the power supply. The second trigger 14 is arranged on one side of the first trigger 13 for contacting or disconnecting with the first trigger 13. The contact of the first trigger 13 with the second trigger 14 and the disconnection action of the first trigger 13 with the second trigger 14 realizes a switching function, which controls the on-off between the plug-in pieces 112 and the power supply. Only when the first trigger 13 contacts the second trigger 14, the plug-in pieces 112 will be powered. When the first trigger 13 is disconnected from the second trigger 14, the plug-in pieces 112 are de-energized.

[0044] Specifically, if the first protective door 121 is configured to be able to translate parallel to the insertion direction of the plug pins, the first protective door 121 is connected to the first trigger part 13, so that the translation of the first protective door 121 will drive the first trigger part 13 to move. When the plug pins of the plug are inserted into the first socket 111, the plug pins will contact the first protective door 121 and push the first protective door 121 to translate along a direction parallel to the plug-in part 112, thereby triggering the translation of the first trigger part 13. In order to ensure that the first trigger part 13 can effectively contact and disconnect with the second trigger part 14 located on one side of the first trigger part 13, the first trigger part 13 can be arranged on one side of the first protective door 121. Specifically, the first trigger part 13 can be located on the side of the direction of the translation movement of the first protective door 121 along the plug-in part 112 when the plug pins of the plug are inserted into the first socket 111, or on the four sides perpendicular to this movement direction, so as to ensure that the second trigger part 14 is located on the movement path of the first trigger part 13, and the first trigger part 13 can contact the second trigger part 14.

[0045] Specifically, if the first protective door 121 is configured to be able to rotate relative to the plug-in part 112, the first trigger part 13 can be arranged on the side opposite to the rotation axis of the first protective door 121 or on the circumferential side close to the rotation axis. In this way, when the first protective door 121 rotates, the first trigger part 13 can effectively contact and disconnect with the second trigger part 14 located on one side of the first trigger part 13 through the change of its position.

[0046] Such a layout can ensure that when the first protective door 121 moves due to the insertion of the plug pins, the first trigger part 13 can smoothly contact and disconnect with the second trigger part 14. The position layout of the first trigger part 13 and the first protective door 121 is not limited to the above layout, as long as the first trigger part 13 and the second trigger part 14 can contact after the plug pins are inserted into the safety socket 10.

[0047] As for the logic of the power supply of the plug-in part 112 after the first trigger part 13 and the second trigger part 14 contact. The first trigger part 13 and the second trigger part 14 can be connected in series with the live wire connected to the plug-in part 112 as a simple switch; or the first trigger part 13 and the second trigger part 14 can be connected to the control system as a signal generating device, and the control system controls the power supply of the plug-in part 112.

[0048] Specifically, the first trigger part 13 and the second trigger part 14 are connected in series with the live wire (i.e. the main power line) of the plug-in part 112. When the socket is not in use, the first trigger part 13 and the second trigger part 14 are in a disconnected state, the circuit is disconnected, and no current passes through. After the user inserts the plug, the plug pins push the first protective door 121 to drive the first trigger part 13 to displace, so that the first trigger part 13 and the second trigger part 14 contact, the live wire is connected to the plug-in part 112, and the current can flow after the plug-in part 112 contacts the load.

[0049] Specifically, the first trigger 13 and the second trigger 14 are electrically connected to a control system, which is electrically connected to the plug-in 112 or a control switch. The control system detects whether the first trigger 13 and the second trigger 14 are in contact. After the control system detects a signal from the contact between the first trigger 13 and the second trigger 14, the control system makes a response according to a preset logic or program to power on or power off the plug-in 112.

[0050] The safety socket 10 provided in the present application is powered on only when the plug is correctly inserted and the first trigger 13 and the second trigger 14 are in normal contact, which ensures the safe closure of the circuit. This not only enhances the safety during use, but also effectively avoids accidental electric shock caused by improper plug insertion or damage to the protective door.

[0051] Please refer to Figure 3 In some specific embodiments, in addition to the first socket 111, the shell 11 is also provided with a second socket 113. This allows the socket to simultaneously meet the connection needs of various electrical appliances, improving the use efficiency and applicability of the socket. Similarly, the second socket 113 is not a single "socket", but one of a two-pin socket, a triangular socket or other types of sockets. The protection assembly 12 also includes a second protective door 122 located above the plug-in 112 and below the second socket 113. The second protective door 122 is similar to the first protective door 121, providing physical isolation and protection to prevent dust and moisture from entering the interior of the socket, while remaining closed when there is no plug inserted to prevent accidental electric shock.

[0052] Please refer to Figure 1 and Figure 4In some embodiments, the second trigger 14 is mounted on one side of the second shield door 122 and moves with the second shield door 122. Specifically, similar to the first shield door 121, the second shield door 122 not only provides physical isolation and protection against external substances entering the socket, but also enables the corresponding plug to trigger the safety function of the corresponding plug-in 112 (the plug-in 112 corresponding to the second shield door 122 or the entire safety socket 10) by physically moving to turn on or off the power supply. The second trigger 14 is mounted on one side of the second shield door 122 and moves with the second shield door 122. When the plug pin is inserted into the second socket 113 and pushes the second shield door 122, the second trigger 14 moves with it, and the plug-in 112 can only be powered on when the second trigger 14 contacts the first trigger 13. The specific position of the second trigger 14 is similar to the position of the first trigger 13, as long as it can achieve the normal contact and disconnection of the first trigger 13 and the second trigger 14 caused by the movement of the first shield door 121 and the second shield door 122. This unified design not only enhances the safety features of the safety socket 10, but also simplifies the manufacturing process of the safety socket 10, while improving the user's familiarity and ease of use of the product.

[0053] Please refer to Figure 4 In some embodiments, the first trigger 13 is fixed to the first shield door 121. Specifically, the first trigger 13 is fixed to the first shield door 121, and this fixed design makes the position of the first trigger 13 closely related to the movement of the first shield door 121. When the first shield door 121 is pushed by the plug pin, the first trigger 13 also moves, thereby ensuring that the operation of the first trigger 13 is synchronized with the state of the first shield door 121. Because the first trigger 13 is directly fixed to the first shield door 121, the movement of the first trigger 13 accurately reflects the insertion state of the plug pin. Such configuration optimizes the reaction speed and accuracy of the first trigger 13, ensuring that the power supply will only be turned on when the plug pin is correctly inserted and the shield door is fully opened. This improves the safety of the safety socket 10 and prevents the power supply from being mistakenly turned on due to incomplete insertion or incorrect operation. At the same time, fixing the first trigger 13 to the first shield door 121 simplifies the mechanical structure of the entire safety socket 10, reduces the number of moving parts, and reduces the number of possible failure points. This design not only improves the reliability of the safety socket 10, but also facilitates maintenance and repair.

[0054] Please continue to refer to Figure 4In some specific embodiments, the first protective door 121 is provided with a clamping groove 123, and the first trigger part 13 is clamped in the clamping groove 123. Specifically, a special clamping groove 123 is provided on the first protective door 121, which is used to fix and position the first trigger part 13. The provision of the first clamping groove 123 enables the first trigger part 13 to accurately cooperate with the movement of the first protective door 121, thereby ensuring the synchronization and accuracy of the operation. The first trigger part 13 is clamped in the clamping groove 123 of the first protective door 121. This fixing mode not only ensures the stability of the first trigger part 13 during operation, but also improves the reliability and durability of the overall assembly. When the first protective door 121 moves, the first trigger part 13 moves accurately, realizing the contact or disconnection of the first trigger part 13 and the second trigger part 14, and controlling the on-off of the plug-in part 112 and the power supply. At the same time, by fixing the first trigger part 13 in the clamping groove 123, the risk of operation failure or safety accidents caused by loose or misaligned parts is greatly reduced. It ensures that each operation can meet the expected safety and efficiency standards. This design also simplifies the assembly and maintenance of the safety socket 10, making it quick and accurate when maintenance or replacement is needed.

[0055] In some specific embodiments, the first trigger part 13 is provided as a spring piece that elastically abuts against the first protective door 121. Specifically, when the plug pin is inserted and pushes the first protective door 121, the first trigger part 13 connected to the first protective door 121 is compressed, thereby storing potential energy. This compressed state allows the first trigger part 13 to maintain the necessary pressure when it comes into contact with the second trigger part 14, ensuring reliable electrical contact between the first trigger part 13 and the second trigger part 14 and realizing the conduction of the power supply. When the plug pin is pulled out of the socket, the first protective door 121 starts the reset process, and at this time the potential energy stored in the first trigger part 13 is released, pushing the first protective door 121 to quickly return to the initial position. This rapid rebound effect helps to disconnect the power supply, increasing the response speed and safety of the operation.

[0056] In some specific embodiments, the first trigger part 13 is provided as a flexible conductive part or is connected to a flexible conductive part. Specifically, the first trigger part 13 is provided as a flexible conductive part; the first trigger part 13 is directly made of a flexible conductive material, such as braided wire, conductive cloth or conductive rubber, etc. This design enables the first trigger part 13 itself to have both conductivity and flexibility, allowing it to maintain continuous and stable electrical connection when the first protective door 121 moves. When the first protective door 121 moves, causing the first trigger part 13 (flexible conductive part) to move accordingly, the flexibility of the flexible conductive part allows it to naturally bend under stress without breaking, thereby achieving stable power control. Using a flexible conductive part as the first trigger part 13 increases the durability and safety of the safety socket 10.

[0057] Specifically, the first trigger connection flexible conductive part; the first trigger part 13 is connected with the power supply or control system through a flexible conductive part, which can be a flexible conductive connector such as braided wire, conductive cloth or conductive rubber. The first trigger part 13 itself can be a hard material with conductive properties, and flexible connection is achieved through the flexible conductive part. The flexible conductive part ensures that when the first protective door 121 and the first trigger part 13 move, the connection between the first trigger part 13 and the power supply or control system will not be disconnected due to physical displacement. This design allows the first trigger part 13 to have more flexible mechanical design when necessary, while ensuring the stability and safety of the electrical connection through the flexible conductive part.

[0058] Please refer to Figure 1 and Figure 4 In some specific embodiments, the safety socket 10 also includes a partition plate 16 located above the plug-in part 112 and below the first protective door 121. The partition plate 16 provides physical isolation for the plug-in part 112 inside the socket, which helps to further prevent dust, water droplets or other foreign matter from directly contacting the electrical elements, thereby enhancing safety. At the same time, the partition plate 16 also provides a support platform for the first protective door 121 and the second protective door 122.

[0059] Please refer to Figure 1 and Figure 5 The partition plate 16 is provided with a limiting block 161, and the first protective door 121 abuts against the limiting block 161 when it is reset. The main function of the limiting block 161 is to abut against the first protective door 121 and the second protective door 122 when they are reset (i.e. return to the original closed position), and limit the first protective door 121 and the second protective door 122, so as to ensure that the first protective door 121 and the second protective door 122 can stop at the correct position. This design ensures that the first protective door 121 and the second protective door 122 always remain in a safe closed position in the non-use state, ensuring the stability of the protective door and avoiding potential safety hazards caused by incorrect position of the protective door.

[0060] Please refer to Figure 5In some specific embodiments, the inner side of the shell 11 is provided with sliding rails 17, and the first protective door 121 slides along the sliding rails 17. Specifically, the inner side of the shell 11 of the safety socket 10 is equipped with sliding rails 17, which are designed for the movement of the first protective door 121 and the second protective door 122, ensuring that the first protective door 121 and the second protective door 122 can smoothly slide along the set path (sliding rails 17). The two sides of the first protective door 121 and the second protective door 122 are equipped on the sliding rails 17, so that the first protective door 121 and the second protective door 122 move smoothly along the sliding rails 17 when the plug is inserted or pulled out. The arrangement of the sliding rails 17 reduces the risk of possible misoperation in the movement of the first protective door 121 and the second protective door 122, such as deviation from the track or accidental opening and closing, thereby increasing the safety of the safety socket 10 during use.

[0061] In some specific embodiments, the first trigger part 13 and the second trigger part 14 are electrically connected to an external control system, and the external control system is electrically connected to the plug-in connector 112. By electrically connecting the first trigger part 13 and the second trigger part 14 to the external control system and electrically connecting the plug-in connector 112 to the external control system, the entire safety power supply system can be more intelligent and automated. The external control system detects whether the first trigger part 13 and the second trigger part 14 are in contact, and when the control system detects a signal from the first trigger part 13 and the second trigger part 14, it responds by powering on or powering off the plug-in connector 112 according to a pre-set logic or program. The presence of the external control system improves the safety and reliability of the socket and can handle various electrical safety scenarios.

[0062] Embodiment Two

[0063] Please refer to Figure 6 In the second embodiment of the present application, a safety socket 10 is provided, which is different from the safety socket 10 in the first embodiment in that it further includes a third trigger part 15, which is arranged on one side of the second protective door 122 and moves with the second protective door 122. Moreover, the second trigger part 14 is no longer arranged on the second protective door 122, but is arranged between the first trigger part 13 and the third trigger part 15.

[0064] The third trigger part 15 is arranged on one side of the second protective door 122 and moves with the second protective door 122, so that the third trigger part 15 can realize contact or disconnection operation with the second trigger part 14 when the second protective door 122 moves. The main function of the third trigger part 15 is to cooperate with the second trigger part 14 to form a switching mechanism for controlling the on-off of the plug-in connector 112. The third trigger part 15 is located on one side of the second trigger part 14, and the second trigger part 14 is arranged between the first trigger part 13 and the third trigger part 15.

[0065] Specifically, when the first trigger portion 13 contacts the second trigger portion 14, the corresponding plug-in connector 112 is powered; when the third trigger portion 15 contacts the second trigger portion 14, the corresponding plug-in connector 112 is powered. The first trigger portion 13 and the third trigger portion 15 can also contact the second trigger portion 14 at the same time, so that the corresponding plug-in connector 112 is powered at the same time. Of course, it can also be set that when the first trigger portion 13 contacts the second trigger portion 14 or the third trigger portion 15 contacts the second trigger portion 14, the plug-in connector is powered.

[0066] The safety socket 10 provided by the embodiment provides more advanced safety operation and more accurate power control by setting the third trigger portion 15 and optimizing the position of the second trigger portion 14. The precise cooperation of the second trigger portion 14 with the first trigger portion 13 and the third trigger portion 15 ensures that the power supply can be quickly disconnected in abnormal or dangerous situations, thereby protecting the safety of users and electrical equipment. In the embodiment of separately controlling the power supply of the corresponding plug-in connector, the control system can also accurately cut off the power supply of the fault circuit while ensuring the normal use of the non-fault circuit.

[0067] Regarding the logic of the second trigger portion 14 contacting the first trigger portion 13 and the second trigger portion 14 contacting the third trigger portion 15 to power the plug-in connector 112. The first trigger portion 13, the second trigger portion 14, and the third trigger portion 15 can be connected in series as simple switches with the live wire connected to the corresponding plug-in connector 112; or the first trigger portion 13, the second trigger portion 14, and the third trigger portion 15 can be connected to the control system as signal generating devices. The signal generating device can be a sensor, such as a capacitive, inductive, or resistive sensor, or directly use the on-off between the trigger portions as a signal to ensure accuracy and reliability.

[0068] In a specific way, the first trigger portion 13, the second trigger portion 14, and the third trigger portion 15 are connected in series as simple switches with the live wire connected to the corresponding plug-in connector 112. The second trigger portion 14 is connected in series with the power supply live wire, and the first trigger portion 13 and the third trigger portion 15 are respectively connected in series with the live wire of the corresponding plug-in connector 112. When the socket is not in use, the first trigger portion 13 and the second trigger portion 14, and the third trigger portion 15 and the second trigger portion 14 are in the off state, the circuit is disconnected, and no current passes through. After the user inserts the plug, the plug pin pushes the first protective door 121 to displace the first trigger portion 13, or the plug pin pushes the second protective door 122 to displace the third trigger portion 15, so that the first trigger portion 13 and the second trigger portion 14 are in contact, and the third trigger portion 15 and the second trigger portion 14 are in contact. The power supply live wire is connected in conductive with the plug-in connector 112 live wire, and the current can flow after the plug-in connector 112 contacts the load.

[0069] In another specific mode, the first trigger portion 13, the second trigger portion 14 and the third trigger portion 15 are all electrically connected to a control system, and the control system is electrically connected to the plug-in piece 112 or a control switch. The external control system detects whether the first trigger portion 13 and the second trigger portion 14, the third trigger portion 15 and the second trigger portion 14 are in contact, and after the control system detects the corresponding signal, the control system makes a response of powering on or powering off the corresponding plug-in piece 112 according to a preset logic or program.

[0070] The safety socket 10 provided in the application ensures that the corresponding plug-in piece 112 is powered on only when the plug is correctly inserted and the first trigger portion 13 and the second trigger portion 14 are in normal contact or the third trigger portion 15 and the second trigger portion 14 are in normal contact, which ensures the safe closing of the circuit. This enhances the safety of the safety socket 10 during use and effectively avoids accidental electric shock caused by improper plug insertion or damage of the protective door.

[0071] Embodiment three

[0072] The third embodiment of the application provides a safety power supply system, which comprises the safety socket 10 and a control system as described above.
