Abstract
Description
Technical Field
[0001] This invention belongs to the field of low-voltage building electrical appliances, specifically relating to a socket protection door assembly and a socket. Background Technology
[0002] Existing sockets generally have protective shutters to prevent accidental electric shock. Currently, these shutters are driven by the grounding electrode, requiring a grounding pin to activate them before they can connect to the grounding socket. The shutters are typically aircraft-shaped, resulting in large, wasteful parts and three square holes with significant size differences on the surface, making the product unsightly and prone to accumulating dust and dirt that is difficult to clean. Patent CN110212352A, entitled "Sequential Rotation Socket Protective Door," discloses a protective door structure, but while it provides protection against electric shock, plugging and unplugging is cumbersome. It requires a specific sequence; otherwise, direct insertion may be blocked. This is inconvenient in emergencies or for first-time users, as many people are unsure how to plug and unplug them. Therefore, designing a simple and practical electric shock-proof socket protective door component is essential. Summary of the Invention
[0003] In view of the above-mentioned prior art, the purpose of this invention is to provide a convenient socket protection door assembly and socket.
[0004] The technical solution of the present invention is implemented as follows: A socket protection door assembly includes a bracket and a rotating door. The rotating door is installed together with the bracket in a manner that allows it to rotate relative to the bracket. The rotating door is provided with an elastic reset structure. A first inclined surface and a second inclined surface are symmetrically arranged on the rotating door near the bracket. A matching first inclined rib and a second inclined rib are symmetrically arranged on the bracket near the rotating door. When the rotating door moves axially near the bracket under the action of external force, it squeezes the elastic reset structure. After moving axially a certain distance, the first inclined surface contacts the first inclined rib and the second inclined surface contacts the second inclined rib, so that the axial movement generates a circumferential rotational force that drives the rotating door to rotate relative to the bracket.
[0005] The beneficial effects of this design are: when the plug is inserted into the socket, it can push the rotating door to move axially. When the first and second inclined surfaces contact the first and second inclined ribs, the axial movement can generate a circumferential rotational force to drive the rotating door to rotate relative to the bracket. This allows the rotating door to be opened so that the plug can be smoothly inserted into the socket. When a foreign object is inserted on one side, the force is uneven and it is difficult to drive the rotating door to rotate, thus achieving the function of preventing electric shock. The rotating door design is compact and saves materials, making the socket look flat and more beautiful.
[0006] Furthermore, the first and second inclined ribs are curved in an arc shape to ensure contact with the first and second inclined surfaces at the same position. Compared to setting a large inclined surface, this design saves materials, and relatively reduces resistance and makes rotation easier.
[0007] Furthermore, the revolving door is provided with a first protrusion and a second protrusion. The first protrusion and the second protrusion are the same size as the socket holes on the socket, so that the first protrusion and the second protrusion can fill the gap formed by the socket holes. This design makes the surface of the socket flatter and more beautiful, safer to use, and easier to clean as there are no concave areas.
[0008] Furthermore, the bracket has a left wall and a right wall, and the left wall and the right wall are provided with anti-rotation protrusions. The anti-rotation protrusions have a first height in the axial direction. The outer ends of the first and second convex doors are provided with limiting protrusions. When the rotating door is not subjected to external force, the anti-rotation protrusions can restrict the circumferential rotation of the limiting protrusions. In this way, when the plug is inserted, the axial movement of both sides by the first height distance can start to rotate. If the force is applied to one side, it will not rotate because the other end is locked by the anti-rotation protrusion under the action of the elastic reset structure. This can achieve a good function of preventing accidental contact or foreign object insertion into the socket.
[0009] Furthermore, a slanted spring is provided between the first and second convex gates and the support. The slanted spring can generate axial force and circumferential force, so the slanted spring has a reset function in the axial direction and an auxiliary rotation function in the circumferential direction.
[0010] A socket includes a faceplate, a bottom shell, and terminals, as well as the aforementioned protective door assembly, which can prevent electric shock, has a more aesthetically pleasing overall appearance, is easier to clean, and is safer to use.
[0011] Furthermore, the cover is equipped with positioning posts for installing protective door components, which facilitates assembly and enables modular design.
[0012] Furthermore, the cover is provided with a third and a fourth inclined rib. The third and fourth inclined ribs are curved in an arc shape and are set on the front and rear sides of the first and second convex doors, respectively, which makes it easier to reset and avoids the situation where the revolving door cannot be reset in the circumferential direction. The third, fourth, first, and second inclined ribs form a complete sliding track, which can limit the movement trajectory of the revolving door.
[0013] Furthermore, the faceplate is equipped with a silicone dustproof sheet, which serves to prevent dust accumulation.
[0014] Furthermore, the socket is a British-style socket, which is a better match for the design. Attached Figure Description

[0027] Detailed embodiments of the invention are disclosed herein as needed; however, it should be understood that the disclosed embodiments are merely illustrative of the invention, and the invention may be implemented in different and alternative forms. The drawings are not necessarily drawn to scale, and certain features may be exaggerated or reduced to show details of specific components. Therefore, the specific structural and functional details disclosed herein should not be construed as limiting, but rather as a representative basis to teach those skilled in the art to employ the invention differently. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of this invention.
[0028] like Figure 2-9As shown, a socket protection door assembly includes a bracket 1 and a rotating door 2. The rotating door 2 is mounted to the bracket 1 in a rotatable manner relative to the bracket 1. The rotating door 2 is provided with an elastic reset structure 3. A first inclined surface 4 and a second inclined surface 5 are symmetrically arranged on the rotating door 2 near the bracket 1. A matching first inclined rib 6 and a second inclined rib 7 are symmetrically arranged on the bracket 1 near the rotating door 2. When the rotating door 2 moves axially near the bracket 1 under the action of external force, it compresses the elastic reset structure 3. After moving a certain distance axially, the first inclined surface 4 contacts the first inclined rib 6 and the second inclined surface 5 contacts the second inclined rib 7, causing the axial movement to generate a circumferential rotational force that drives the rotating door 2 to rotate relative to the bracket 1. The first inclined rib 6 and the second inclined rib 7 are curved in an arc shape to ensure that they contact the first inclined surface 4 and the second inclined surface 5 at the same position. The revolving door 2 is provided with a first protrusion 8 and a second protrusion 9. The first protrusion 8 and the second protrusion 9 are the same size as the socket holes on the socket, so that the first protrusion 8 and the second protrusion 9 can fill the gap formed by the socket holes. In this way, even if the first protrusion 8 or the second protrusion 9 moves a certain distance axially, the socket holes can still be kept blocked. The bracket 1 is provided with a left wall 10 and a right wall 11. The left wall 10 and the right wall 11 are provided with anti-rotation protrusions 13. The anti-rotation protrusions 13 have a first height in the axial direction. The outer ends of the first protrusion 8 and the second protrusion 9 are provided with limiting protrusions 12. When the revolving door 2 is not subjected to external force, the anti-rotation protrusions 13 can restrict the circumferential rotation of the limiting protrusions 12. An inclined spring 14 is provided between the first protrusion 8 and the second protrusion 9 and the bracket 1. The inclined spring 14 can generate axial force and circumferential force.
[0029] like Figure 10 and Figure 11 As shown, when one side of the revolving door 2 moves axially to a first height, it can unlock on one side. However, when the revolving door 2 is tilted, the other side is locked by the anti-rotation protrusion 13 and cannot rotate.
[0030] like Figure 1-12As shown, a socket includes a faceplate 15, a bottom shell 16, and terminals 17. The bottom shell 16 can be fitted with positioning terminals 17. The faceplate can be snapped onto the bottom shell 16 or fixed to the bottom shell 16 by screws. The socket also includes the aforementioned protective door assembly, which is located between the faceplate 15 and the bottom shell 16. The faceplate 15 and the bottom shell 16 limit and fix the protective door assembly. The faceplate 15 has positioning posts 18 for installing the protective door assembly, allowing for direct insertion and limiting. The faceplate 15 has a third inclined rib 19 and a fourth inclined rib 20, which are curved in an arc shape and are correspondingly arranged on the front and rear sides of the first protrusion 8 and the second protrusion 9, respectively. The faceplate 15 has a silicone dustproof sheet 21, which is positioned above the grounding plug terminal 22. A rotating shaft 23 is provided on the rear side of the cover 15. The rotating shaft 23 includes an upper half shaft 24 and a lower half shaft 25, with a gap between the upper half shaft 24 and the lower half shaft 25. The rotating door 2 has a rotating hole 26, into which the rotating shaft 23 can be inserted. The bracket 1 also has a corresponding fixing hole 27. The head of the rotating shaft 23 has an arc-shaped protrusion 28. The upper half shaft 24 is close to the lower half shaft 25, which reduces the radial distance between the upper half shaft 24 and the lower half shaft 25. In this way, the rotating shaft 23 can be inserted into the fixing hole 27 and the position of the bracket 1 is limited by the arc-shaped protrusion 28. The elastic reset structure 3 is a reset spring 29. The reset spring 29 is installed on the periphery of the rotating shaft 23. One end of the reset spring 29 is limited and fixed by the rotating door 2, and the other end is limited and fixed by the bracket 1. A limiting hole 30 is provided on the rotating door 2, into which one end of the reset spring 29 can be inserted. In this way, the reset spring 29 not only has a reset function in the axial direction, but also in the circumferential direction. The socket is a British-style socket with a large opening, making it difficult for ordinary structures to prevent the insertion of foreign objects.
