AI Technical Summary
Existing US-standard smart sockets have safety shutters that cannot effectively protect against the insertion of foreign objects on one side, posing a safety hazard.
A safety door assembly for preventing single-insertion mis-insertion is designed, including a safety door, a spring, and a safety door cover. Through the cooperation of the inclined groove and the rotating shaft, the safety door slides out of the socket when the plug is inserted normally, and the safety door rotates to block the socket when a single plug is inserted, thus preventing mis-insertion.
It effectively prevents the insertion of single foreign objects, improves the safety of the socket, and ensures the normal connection between the plug and the socket.

Abstract
Description
Technical Field
[0001] This utility model relates to smart sockets, and more particularly to a US standard smart socket with a safety door to prevent accidental insertion of a single wire. Background Technology
[0002] Currently, many US-standard smart sockets on the market do not have safety shutters. Even those that do have safety shutters may still fail to provide protection if a foreign object is inserted on one side, as the shutter will be pushed open and the copper parts will be exposed. This still poses a safety risk.
[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a US-standard smart socket that prevents accidental insertion of a single wire into the safety door.
[0005] The technical solution of this utility model is as follows: This utility model provides a US standard smart socket with a safety door to prevent single-insertion misplacement, comprising: a bottom shell, a front shell, a power board, a control board, a button assembly, and a safety door assembly. The bottom shell and the front shell are assembled to form a receiving space. The power board, control board, button assembly, and safety door assembly are all disposed within the receiving space. The power board is fastened to the bottom shell by screws. The control board, button assembly, and safety door assembly are all disposed on the front shell. The control board is electrically connected to the power board. The safety door assembly comprises: a safety door, a spring, and a safety door cover. The safety door cover is disposed on the front shell and correspondingly located on the front shell. At the insertion hole position, the spring and safety door are located between the face shell and the safety door cover. The safety door cover has a clearance hole corresponding to the insertion hole position. The safety door cover has a guide groove corresponding to the safety door. The safety door has a slanted groove and an insertion position corresponding to the L insertion hole and N insertion hole. Under the action of the spring, the safety door blocks the clearance hole of the L insertion hole and N insertion hole through the slanted groove. A pivot part is formed in the middle of the safety door. The safety door can rotate and slide relative to the safety door cover. A protrusion is formed on the safety door cover for limiting the rotation of the safety door. The safety door has a matching rotation limiting part corresponding to the protrusion.
[0006] Furthermore, the button assembly includes: a light-guiding button and a button cover disposed on the light-guiding button, wherein the light-guiding button is fixed to the cover by a hot-melt post.
[0007] Furthermore, the control board is electrically connected to the power board via a connector.
[0008] Furthermore, the bottom shell and the top shell are assembled using screw fastening and snap-fit fixing methods.
[0009] Furthermore, the safety door cover is fixed to the faceplate by a hot-melt column.
[0010] The beneficial effect of this utility model by adopting the above solution is that the safety door component can effectively protect against single insertion, thereby improving safety. Attached Figure Description

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] Please refer to the following: Figures 1 to 9In this embodiment, the present invention provides a US standard smart socket with a safety door to prevent single-plug misinsertion, comprising: a bottom shell 1, a front shell 7, a power board 2, a control board 3, a button assembly, and a safety door assembly. The bottom shell 1 and the front shell 7 are assembled to form a receiving space. The power board 2, control board 3, button assembly, and safety door assembly are all disposed within the receiving space. The power board 2 is fastened to the bottom shell 1 by screws. The control board 3, button assembly, and safety door assembly are all disposed on the front shell 7. The control board 3 is electrically connected to the power board 2. The safety door assembly comprises: a safety door 5, a spring 6, and a safety door cover 4. The safety door cover 4 is disposed on the front shell 7 and is located at the corresponding plug hole position on the front shell 7. The spring 6 and the safety door 5 are located between the front shell 7 and the safety door cover 4. The safety door cover 4 has a clearance hole corresponding to the plug hole position, allowing the plug to pass through the plug hole on the front shell 7. The safety door cover 4 is electrically connected to the L-type socket, N-type socket, and ground socket. A guide groove 41 is formed on the safety door cover 4 corresponding to the safety door 5. The guide groove 41 serves to limit and guide the safety door 5 when it slides within the safety door cover 4. An inclined groove 51 and an insertion position are formed on the safety door 4 corresponding to the L-type and N-type sockets. The plug can push the inclined groove 51 to move the safety door 5 and expose the insertion position, so that the plug can contact the socket below. Under the action of the spring 6, the safety door 5 blocks the clearance holes of the L-type and N-type sockets through the inclined groove 51. A pivot part 52 is formed in the middle of the safety door 5. The safety door 5 can rotate and slide relative to the safety door cover 4. A protrusion 42 is formed on the safety door cover 4 to limit the rotation of the safety door 5. A matching rotation limiting part 53 is formed on the safety door 5 corresponding to the protrusion 42.
[0022] Furthermore, the button assembly includes: a light-guiding button 8 and a button cover 9 disposed on the light-guiding button 8. The light-guiding button 8 has the functions of guiding light and pressing buttons. The light-guiding button 8 is fixed on the cover 7 by a hot-melt post.
[0023] Furthermore, the control board 3 is electrically connected to the power board 2 via a connector.
[0024] Furthermore, the bottom shell 1 and the top shell 7 are assembled by means of screw fastening and snap fastening.
[0025] Furthermore, the safety door cover 4 is fixed to the faceplate 7 by a hot-melt column.
[0026] In this design, under normal conditions, the safety door 4 blocks the L and N sockets under the action of the spring 6. When a plug is inserted normally, both the L and N terminals in the plug push the safety door 5 to slide through the inclined groove 51, compressing the spring 6. After the safety door 5 slides into place, the clearance hole of the safety door cover 4 below is exposed, allowing the plug to pass through the clearance hole and connect to the L and N sockets below. When a single item is inserted into only the L or N socket, due to the presence of the pivot 52 of the safety door 5, the two inclined grooves 51 are subjected to uneven force, causing the safety door 5 to rotate relative to the safety door cover 4. This causes the rotation limit part 53 of the safety door 5 to be blocked by the protrusion 42 of the safety door cover 4, restricting the travel of the safety door 5 and preventing the clearance hole and L and N sockets from being exposed, thus avoiding contact between the inserted object and the sockets and ensuring safety performance.
[0027] In summary, this solution, through the safety gate component, can effectively protect against single insertion, thus improving safety.
[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
