If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0048] In the existing technology, there is a method of using an external power source to power the socket. This method is achieved by plugging the plug of the external power source into the socket.
[0049] Under this method, for safety reasons, the plug cannot be unplugged when the socket is powered on; it can only be unplugged when the socket is powered off. However, in practice, there are cases where users accidentally unplug the plug when the socket is powered on, or the plug becomes loose.
[0050] To address the aforementioned issues, this patent provides a safety socket designed to ensure that the plug remains securely inserted into the socket while it is powered on, preventing it from being pulled out.
[0051] For ease of understanding, the specific implementation methods of the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0052] Please see Figure 1-6A safety socket includes a housing 100, a retaining member 200, and a switch 300. The housing 100 has a groove 110, with a first through hole 111 at the bottom for inserting a plug pin. A second through hole 112 is provided on the side wall of the groove 110. The retaining member 200 is movably disposed inside the socket and located at the second through hole 112. The retaining member 200 has a first retaining portion 210 that extends out from the second through hole 112. The switch 300 controls the socket's external power supply and is linked to the retaining member 200. A plug supplies power to the socket and has a second retaining portion 400. When the switch 300 is pressed to connect the circuit inside the socket, the first retaining portion 210 extends out from the second through hole 112 and is retained in the second retaining portion 400 under the action of the switch 300, thus locking the plug into the socket.
[0053] The first holding part 210 can be a protrusion, a protruding post, a protrusion, a hook, etc., while the second holding part 400 can be a groove, a blind hole, a through hole, etc. The linkage between the on / off switch 300 and the holding part 200 can be direct, such as pressing the on / off switch 300 and pushing the holding part 200 towards the second through hole 112; or it can be indirect, such as the holding part 200 being mounted on a movable component, and pressing the on / off switch 300 and pushing the movable component towards the second through hole 112. When the on / off switch 300 is not pressed, the first holding part 210 can be located outside the second through hole 112, or partially or entirely within the second through hole 112. In this embodiment, the first holding part 210 is held by the second holding part 400 to lock the plug and socket connection. This satisfies the requirement that the plug cannot be pulled out when the socket is powered on, ensuring a secure connection.
[0054] Based on the above implementation, the first holding part 210 extending from the second through hole 112 and being held in place by the second holding part 400 under the action of the on / off switch 300 can be implemented in various ways. This embodiment provides the following implementation. Please refer to... Figure 5-7The safety socket also includes a first displacement member 500, and a retaining member 200 disposed on the first displacement member 500. A first inclined surface 510 is formed on the first displacement member 500, and a second inclined surface 310 is formed on the on / off switch 300. When the on / off switch 300 is pressed, the second inclined surface 310 pushes the first inclined surface 510, so that the first displacement member 500 moves toward the second through hole 112. With the help of the first displacement member 500, the retaining member 200 also moves toward the second through hole 112 when the on / off switch 300 is pressed. Furthermore, the first retaining part 210 extends out from the second through hole 112 and retains the second retaining part 400 of the plug. By using the retaining component 200 and the displacement component, the manufacturer can design and produce the displacement component separately according to the different internal structures of the socket to adapt to different sockets. The manufacturer can also design and produce the retaining component 200 separately according to the different second retaining parts 400 of the plug to adapt to different plugs. Finally, the required displacement component and retaining component 200 can be combined and used according to the actual situation.
[0055] Furthermore, there is the question of how to position the retaining member 200 on the first displacement member 500. To solve this problem, this embodiment provides the following implementation method. Please refer to... Figure 7-11 A spring piece 600 is provided between the side wall of the first displacement member 500 and the retaining member 200; a first protrusion 220 is provided on the retaining member 200, and a third retaining part 520 is provided on the first displacement member 500, with the first protrusion 220 embedded in the third retaining part 520. This implementation allows the retaining member 200 to be disposed on the first displacement member 500 and to move with the first displacement member 500.
[0056] Furthermore, there is a problem regarding how to disengage the first holding part 210 from the second holding part 400 after the on / off switch 300 is turned off. To solve this problem, this embodiment provides the following implementation method. Please refer to... Figure 11 The safety socket also includes a first reset spring 700, which is used to reset the first displacement member 500 to its initial position when the on / off switch 300 is closed. The retaining member 200 moves with the first displacement member 500, and during the process of the first reset spring 700 resetting the first displacement member 500, the first retaining part 210 disengages from the second retaining part 400.
[0057] It should be noted that there are other ways to implement the first holding part 210 extending from the second through hole 112 and being held in place by the second holding part 400 under the action of the on / off switch 300. This embodiment provides the following implementation method. Please refer to... Figure 6 , Figure 12 , Figure 13 and Figure 15The safety socket also includes a linkage member 800 and a second displacement member 900, with a retaining member 200 disposed on the second displacement member 900. A third inclined surface 810 is formed on the linkage member 800, and a fourth inclined surface 320 is formed on the on / off switch 300. When the on / off switch 300 is pressed, the fourth inclined surface 320 pushes the third inclined surface 810, causing the linkage member 800 to move and, in turn, the second displacement member 900 to move towards the second through hole 112. This mechanism of linkage 800 moving the second displacement member 900 towards the second through hole 112 allows the second displacement member 900 to be positioned close to the second through hole 112, enabling the first retaining part 210 to be quickly secured to the second retaining part 400. The linkage member 800 ensures that even sockets with a significant distance between the on / off switch 300 and the second through hole 112 can achieve the effect of the second displacement member 900 moving towards the second through hole 112 when the on / off switch 300 is pressed. In addition, the shape of the linkage 800 can be set to avoid the shape of internal components of the socket such as conductors, screws, or socket units 1000, so that when the linkage 800 is pushed by the on / off switch 300, it will not affect the internal components of the socket.
[0058] Based on the above implementation, there is a question of how to position the retaining member 200 on the second displacement member 900. To solve this problem, this embodiment provides the following implementation. Please refer to... Figure 16 A spring piece 600 is provided between the side wall of the second displacement member 900 and the retaining member 200; a second protrusion 230 is provided on the retaining member 200, and a fourth retaining part 910 is provided on the second displacement member 900, with the second protrusion 230 embedded in the fourth retaining part 910. This implementation allows the retaining member 200 to be disposed on the second displacement member 900 and to move with the second displacement member 900.
[0059] Based on the above implementation, there is a problem of how to make the linkage 800 move in conjunction with the second displacement component 900 toward the second through hole 112. To solve this problem, this embodiment provides the following implementation. Please refer to... Figure 16 and Figure 17The linkage 800 includes a linkage arm 820, a fifth inclined surface 920 formed on the second displacement member 900, and a sixth inclined surface 821 formed on the linkage arm 820. When the on / off switch 300 is pressed, the sixth inclined surface 821 pushes the fifth inclined surface 920, causing the second displacement member 900 to move towards the second through hole 112. This implementation ensures that when the on / off switch 300 is pressed, the linkage 800 moves, and simultaneously, the sixth inclined surface 821 pushes the fifth inclined surface 920, causing the second displacement member 900 to move towards the second through hole 112. In the implementation where the linkage 800 includes the linkage arm 820, the linkage arm 820 can extend towards the second through hole 112, thereby adapting to sockets where the second through hole 112 is relatively far from the on / off switch 300.
[0060] Furthermore, the fifth inclined plane 920 can be implemented in various ways; please refer to [link / reference]. Figure 14 and Figure 15 A socket unit 1000 is provided below the groove 110, and the linkage arm 820 is close to the socket unit 1000. The second displacement member 900 has a third protrusion 930, which is located at the bottom of the second displacement member 900. A fifth inclined surface 920 is provided on the third protrusion 930. Since the third protrusion 930 is located at the bottom of the second displacement member 900, when the fifth inclined surface 920 is pushed by the sixth inclined surface 821, it will not affect the movement of the retaining member 200 with the second displacement member 900.
[0061] Furthermore, there is the issue of how to make the connection between the plug and the socket more secure. To solve this problem, this embodiment provides the following implementation method. Please refer to... Figure 15-17 The linkage arm 820, the retaining member 200, the second displacement member 900, and the second through hole 112 are all configured in pairs; the two retaining members 200 are respectively disposed on the two second displacement members 900; the two second through holes 112 are respectively disposed on the two opposite side walls of the groove 110; when the on / off switch 300 is pressed, the sixth inclined surface 821 on the two linkage arms 820 pushes the fifth inclined surface 920 on the two second displacement members 900, so that the two second displacement members 900 move toward the two second through holes 112 respectively. This implementation method makes the plug clamped and fixed from both sides by the retaining members 200, and the plug and socket connection is more secure.
[0062] Based on the above implementation, there is a problem regarding how to disengage the first holding part 210 from the second holding part 400 after the on / off switch 300 is turned off. To solve this problem, this embodiment provides the following implementation. Please refer to... Figure 17The safety socket also includes a second reset spring 1100, which is used to reset the second displacement member 900 to its initial position when the on / off switch 300 is closed. The retaining member 200 moves with the second displacement member 900, and during the process of the second reset spring 1100 resetting the second displacement member 900, the first retaining part 210 disengages from the second retaining part 400.
[0063] It should be noted that the first card-holding part 210 can be implemented in various ways; this embodiment provides the following implementation. Please refer to [link / reference]. Figure 5 The upper surface of the first retaining part 210 is a sloped surface or an arc-shaped convex surface. This implementation allows the retaining member 200 to be reset when its reset effect is poor and its first retaining part 210 still extends out of the second through hole 112, by having the end face of the plug abut against the upper surface of the first retaining part 210. Similarly, this implementation allows the retaining member 200 to be reset by having the end face of the plug abut against the upper surface of the first retaining part 210 without a reset spring or other reset components.
[0064] It should be noted that the on / off switch 300 in this embodiment includes a button 330 and a trigger unit 340. The trigger unit 340 includes a component (such as an elastic element) that allows the button 330 to reset. When the button 330 is pressed again, the button 330 can reset. The button 330 is linked to the retaining member 200. To ensure that after the first retaining part 210 is engaged with the second retaining part 400, the button 330 will not reset or shift unless pressed again, thereby ensuring the retaining effect, this embodiment provides the following implementation method. Please refer to... Figure 18 The housing 100 is equipped with a locking structure 1200 to prevent the button from resetting after the on / off switch 300 is pressed to connect the circuit in the socket. The locking structure 1200 includes a first locking member 1210 fixed to the inside of the button 330 and a second locking member 1220 located below the button 330. The second locking member 1220 is fixed to the trigger unit 340. The lower end of the first locking member 1210 is provided with a clamp 1211, and the upper end of the second locking member 1220 is provided with a claw 1221. When the switch is pressed, the claw 1221 clamps the clamp 1211 so that the button 330 and the trigger unit 340 move synchronously. In this implementation, the second locking member 1220 can be fixed to the trigger unit 340 to a component of the trigger unit 340 used for resetting the button 330. When button 330 is pressed, gripper 1221 moves downward and is held by gripper 1221, thus fixing button 330 relative to trigger unit 340. When second locking member 1220 is fixed to component of trigger unit 340 for button 330 reset, the held button 330 moves synchronously with the component, thus achieving synchronous movement of button 330 and trigger unit 340.
[0065] Based on the above implementation, there is a question of how to implement the gripper 1221 to hold the chuck 1211. To solve this problem, this embodiment provides the following implementation. Please refer to... Figure 18 and 19 The triggering unit includes a trigger housing 341, and a second locking member 1220 is at least partially housed within the trigger housing 341. When the gripper 1221 is housed within the trigger housing 341, the trigger housing 341 drives the gripper 1221 to clamp the chuck 1211. In this implementation, when the gripper 1211 is not housed within the trigger housing 341, it is in an open state. As the gripper 1221 gradually comes into view within the trigger housing 341, it also gradually moves towards the center. The gripper 1221 may be housed within the trigger housing 341 by being pushed by the chuck 1211.
[0066] It should be noted that when the first holding part 210 is held by the second holding part 400, if an external force is applied to the plug (such as manually pulling the plug), the plug may tilt. To avoid this situation, this embodiment provides the following implementation method. Please refer to... Figure 20 The housing 100 is provided with a limiting member 1300, and a limiting protrusion 1310 is formed on the limiting member 1300. When the plug pin 01 is inserted into the first through hole 111, the limiting protrusion 1310 abuts against the plug pin 01 from the side to fix the plug pin 01 from the side. By limiting and fixing the plug pin 01 through the limiting protrusion 1310, the plug pin 01 cannot move or swing, thereby preventing the plug from tilting.
[0067] In summary, the safety socket provided in this application embodiment includes a housing 100, a retaining member 200, and an on / off switch 300; the housing 100 is provided with a groove 110, and the bottom of the groove 110 is provided with a first through hole 111 for inserting the plug pins; the side wall of the groove 110 is provided with a second through hole 112; the retaining member 200 is movably disposed inside the socket and located at the second through hole 112, and the retaining member 200 has a first retaining portion 2. 10.

In this way, the requirement that the plug cannot be pulled out when the socket is powered on is met, and it is securely plugged into the socket.
