Description

Technical Field

[0001] This invention relates to the field of electrical socket technology, and in particular to a socket protection door structure. Background Technology

[0002] Currently, small sockets on the market, such as two-prong sliding rail sockets, typically use covers to prevent accidental insertion. These extra covers not only take up space but also require active user intervention, resulting in poor protection. This is because existing accidental insertion prevention covers are usually complex in structure and bulky, making them unsuitable for small sockets. Therefore, the market urgently needs a compact accidental insertion prevention cover structure to achieve the accidental insertion protection function for small sockets. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a socket protection door structure to achieve protection against misinsertion of small sockets.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A socket protection door structure is installed below two socket holes of a socket, including a bracket frame, a spring and two sliding modules. The bracket frame is rotatably connected to the socket housing on both sides. The bottom of the bracket frame has two through holes, which correspond to the positions of the socket holes. The two sliding modules are symmetrically arranged at both ends of the bracket frame and are respectively located between a set of corresponding through holes and socket holes. The spring is located in the middle of the two sliding modules and is connected to one sliding module at each end.

[0006] Furthermore, the upper end of the sliding module is provided with an inclined surface, which faces the end of the bracket frame and is inclined away from the socket.

[0007] Furthermore, the shapes of the through holes and sockets correspond to each other.

[0008] Furthermore, the sliding module includes a first slider and a second slider, both of which have inclined surfaces at their upper ends. The first slider is connected to a spring, and the second slider is located between the first slider and the end of the support frame.

[0009] Furthermore, the bracket frame has protruding posts in the middle of both sides, and the socket housing has round holes on its inner wall. The protruding posts are inserted into the round holes to form a rotatable connection.

[0010] Furthermore, the support frame is a long box with an opening at the top, and the side wall of the long box is provided with a sliding groove. The sliding module has flanges on both sides, and the flanges are inserted into the sliding groove to form a sliding connection.

[0011] Furthermore, one end of the sliding module is provided with a mounting groove, and one end of the spring is embedded in the mounting groove.

[0012] Compared with the prior art, the present invention has the following advantages: The present invention achieves anti-misinsertion protection through a sliding module and a swingable bracket frame. When a foreign object is inserted into a socket, the bracket frame at the inserted end will rotate downwards, making it difficult for the sliding module to be pushed open; even if the foreign object passes through the moving sliding module, due to the deflection of the through hole and socket position on the bracket frame, the foreign object will be blocked again by the bottom plate of the bracket frame, avoiding direct contact with the internal components of the socket, thus further providing protection.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0019] Example 1

[0020] like Figures 1-3As shown, this embodiment provides a socket protection door structure applied to a two-hole sliding socket 1. The socket protection door structure is installed directly below the two sockets 11 of the socket 1 and includes a support frame 2, a spring 3, and two sliding modules 4. The support frame 2 is a long box with an open top. A protruding post 22 is provided in the middle of the two side walls of the support frame 2, and a corresponding round hole is provided on the inner wall of the socket 1's housing 12. The protruding post 22 is inserted into the round hole to form a rotatable connection, thereby allowing the support frame 2 to swing and rotate around the protruding post 22 on both sides. A stiffening plate is provided at the bottom of the support frame 2 to limit the rotation angle of the support frame 2 and prevent excessive rotation. Two through holes 21 are provided at the bottom of the support frame 2, the shape and position of which correspond to the sockets 11.

[0021] Two sliding modules 4 are symmetrically arranged at both ends within the bracket frame 2 and are respectively located between a set of corresponding through holes 21 and sockets 11. A spring 3 is located between the two sliding modules 4 and is connected to one sliding module 4 at each end. Sliding grooves 23 are provided on both side walls of the bracket frame 2, and flanges 41 are provided on both sides of the sliding modules 4. The flanges 41 are inserted into the sliding grooves 23 to form a sliding connection. Specifically, in this embodiment, the socket 11 of the socket 1 is a composite square and round socket. Therefore, the sliding module 4 includes a first slider 4a and a second slider 4b. The upper ends of both the first slider 4a and the second slider 4b are provided with inclined surfaces, which face the end of the bracket frame 2 and are inclined away from the socket 11. The back of the first slider 4a is also provided with a mounting groove, and one end of the spring 3 is embedded in the mounting groove; the first slider 4a is located below the square hole of the composite square and round socket. The second slider 4b is located between the first slider 4a and the end of the bracket frame 2; and the second slider 4b is located below the round hole of the composite square and round socket.

[0022] The working principle of this embodiment is as follows:

[0023] When plugging a cord into a socket normally, there are two scenarios:

[0024] 1) When the square plug is inserted into the square hole, the first slider 4a on both sides of the bracket frame 2 is subjected to uniform force. Under the action of the plug and the inclined surface, the first slider 4a on both sides compresses the spring 3 and moves towards the middle of the bracket frame 2, thereby avoiding the exposure of the through hole 21 below, so that the square plug passes through the through hole 21 between the first slider 4a and the second slider 4b and is smoothly inserted into the socket 1.

[0025] 2) When the round plug is inserted into the round hole, the second sliders 4b on both sides of the bracket frame 2 are subjected to uniform force. Under the action of the plug and the inclined surface, the second sliders 4b on both sides drive the first slider 4a to jointly compress the spring 3 and move towards the middle of the bracket frame 2, thereby avoiding the exposed through hole 21 below, so that the round plug can pass through the through hole 21 and be successfully inserted into the socket 1.

[0026] When a single plug or a foreign object is inserted into a socket 11, the sliding module 4 located at both ends of the bracket frame 2 is only subjected to force at one end, while the other end is not subjected to force. At this time, the end of the bracket frame 2 subjected to force will rotate and sink, like a seesaw, making it difficult for the sliding module 4 to be pushed open; even if a foreign object passes through the moved sliding module 4, because the positions of the through hole 21 on the bracket frame 2 and the socket 11 are deflected, the foreign object will be blocked again by the bottom plate of the bracket frame 2, and neither the plug nor the foreign object will be able to contact the inside of the socket 1 and the conductive parts, thus preventing abnormal insertion.

[0027] Example 2

[0028] The overall structure of this embodiment is similar to that of Embodiment 1, except that: Figure 2 As shown, the socket 11 of the two-hole slide rail socket is a square hole. The sliding module 4 is a separate sliding block. When the plug is normally inserted into the socket 1, the sliding blocks on both sides of the bracket frame 2 are subjected to uniform force. Under the action of the plug and the inclined surface, the sliding blocks on both sides compress the spring 3 and move towards the middle of the bracket frame 2, thereby avoiding the through hole 21 below, so that the plug can pass through the through hole 21 and be smoothly inserted into the socket 1.

[0029] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
