Description

Technical Field

[0001] This invention relates to the field of electrical technology, and more particularly to a protective door structure for a socket. Background Technology

[0002] A socket is an electronic device used to supply power to a plug. It mainly consists of a housing and a socket. The plug's prongs penetrate the housing's panel to insert into the housing, thereby contacting the socket and receiving power. In related technologies, to prevent electric shock accidents caused by users inserting metal objects into the socket, a protective door structure is installed inside the socket, located between the panel and the socket. When no plug is inserted, the protective door structure blocks the socket on the panel. When the plug is inserted, the plug's prongs push open the protective door structure, releasing the blockage and allowing the plug's prongs to be inserted smoothly. However, because space is needed for the linear movement of the protective door structure, miniaturization of the socket is difficult. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a space-saving, rotatable socket protective door structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This invention provides a protective door structure for a socket, including a protective door component and an elastic component mounted on a base. The protective door component includes a first protective door and a second protective door.

[0006] The first protective door has a first mounting part in the middle, and a first blocking drive surface and a third blocking drive surface at both ends; the second protective door has a second mounting part in the middle, and a second blocking drive surface and a fourth blocking drive surface at both ends.

[0007] The first protective door and the second protective door are hinged together by a first mounting part and a second mounting part, and the first mounting part and the second mounting part are stacked and have the same rotation center;

[0008] When the protective door component is closed, the elastic component drives the first protective door and the second protective door to rotate around the rotation center, so that the first blocking driving surface and the second blocking driving surface abut against each other to form the first driving part, and the third blocking driving surface and the fourth blocking driving surface abut against each other to form the second driving part.

[0009] The first driving part is used to block the first plug hole of the socket, and the second driving part is used to block the second plug hole of the socket;

[0010] When an external force is applied to the first driving part and the second driving part, the protective door component switches from the closed state to the open state. The external force drives the first protective door and the second protective door to rotate in opposite directions around the rotation center, causing the first blocking driving surface and the second blocking driving surface to separate and release the obstruction of the first plug hole. The third blocking driving surface and the fourth blocking driving surface separate and release the obstruction of the second plug hole.

[0011] By making the first and second protective doors rotatably connected, and with the first and second protective doors abutting against each other to form a first driving part that together blocks the first plug hole, and the third and fourth protective doors abutting against each other to form a second driving part that together blocks the second plug hole, when the plug is inserted, the first and second protective doors only need to rotate a small angle in opposite directions to avoid the first and second plug holes. This design occupies little space, greatly reducing the size of the protective door components and saving internal space in the socket, thus reducing the overall size of the socket and achieving a compact and aesthetically pleasing design. The protective door components are positioned between the socket sleeve and the socket hole to prevent small objects from inserting into the socket hole and contacting the socket sleeve, thus improving the safety of the socket. Furthermore, this structure can be applied to three-hole sockets, two-hole sockets, or other multi-hole sockets; it can be applied to both DC and AC sockets, making it widely applicable.

[0012] In one possible implementation, the base is further provided with a mounting shaft, and the first mounting part and the second mounting part are mounted on the mounting shaft, so that the first protective door and the second protective door are hinged on the mounting shaft;

[0013] When the first drive unit and the second drive unit respectively block the first plug hole and the second plug hole of the socket, the direction from the first drive unit to the second drive unit is the first direction, the axial direction of the mounting shaft is the third direction, and the direction perpendicular to the first direction and the third direction is the second direction. In the third direction, the second mounting part of the second protective door is stacked on top of the first mounting part of the first protective door.

[0014] By setting an mounting shaft on the base, the first protective door and the second protective door are rotatably mounted on the mounting shaft through the first mounting part and the second mounting part, which can realize the fixed installation of the protective door components and the base. At the same time, the second mounting part of the second protective door is stacked on top of the first mounting part of the first protective door in a third-party upward direction, which can reduce the volume of the protective door, save the internal space of the socket, and thus reduce the volume of the socket, making the socket compact and beautiful.

[0015] Furthermore, when the first driving part and the second driving part respectively block the first plug hole and the second plug hole of the socket, there is a gap between the mounting shaft and the first mounting part and the second mounting part in the first direction, and there is a gap between the first driving part and the second driving part and the base in the third direction; when the external force is applied only to the first driving part or the second driving part, the first protective door and the second protective door tilt towards the base in the third direction and are limited by the single-insertion limiting structure in the base, so that the first protective door and the second protective door cannot rotate.

[0016] Furthermore, the single-insertion limiting structure includes a plurality of first limiting protrusions disposed on the base. When the first driving part and the second driving part respectively block the first plug hole and the second plug hole of the socket, at least one first limiting protrusion is disposed on each side of the lower gap between the two ends of the first protective door and the second protective door. When an external force is applied to the first driving part or the second driving part and one end of the protective door component abuts against the base, the end is placed inside the first limiting protrusions on both sides, so that the first protective door and the second protective door cannot rotate in opposite directions.

[0017] By having a gap between the mounting shaft and the first and second mounting parts in the first direction, and a gap between the first and second driving parts and the base in the third direction, when one end of the first or second driving part is subjected to force, that end will tilt toward the base. By setting a single-insertion limiting structure to limit the tilted end, the first and second protective doors are prevented from rotating in opposite directions, so that the driving part continues to shield and protect the first and second plug holes. This can improve the safety of the socket during use and prevent small objects from being inserted into the socket alone from the first or second plug hole, thus avoiding safety hazards.

[0018] Furthermore, the first mounting part and the second mounting part abut against the mounting shaft in the second direction, limiting them in the second direction. While the first mounting part and the second mounting part have a gap with the mounting shaft in the first direction and can swing, the first mounting part and the second mounting part can rotate in the second direction to match the mounting shaft, ensuring the smoothness of rotation.

[0019] In one possible implementation, the first protective door includes two first blocking rods respectively connected to the radial sides of the first mounting portion, and the ends of the two first blocking rods are respectively provided with a first blocking driving surface and a third blocking driving surface. The second protective door includes two second blocking rods respectively connected to the radial sides of the second mounting portion, and the ends of the two second blocking rods are respectively provided with a second blocking driving surface and a fourth blocking driving surface. The first blocking driving surface, the second blocking driving surface, the third blocking driving surface and the fourth blocking driving surface are all inclined surfaces, and a first driving portion forming a V-shaped groove when the first blocking driving surface abuts against the second blocking driving surface, and a second driving portion forming a V-shaped groove when the third blocking driving surface abuts against the fourth blocking driving surface.

[0020] By setting the first shielding drive surface, the second shielding drive surface, the third shielding drive surface and the fourth shielding drive surface as inclined structures, when the plug is inserted into the socket along the third direction, the first protection door and the second protection door can generate a force that rotates in opposite directions, driving the first protection door and the second protection door to rotate.

[0021] Furthermore, both the first mounting portion of the first protective door and the second mounting portion of the second protective door are hollow structures with rotating holes. The hollow structure is in the shape of a frustum. The bottom diameter of the frustum of the second mounting portion is smaller than the top diameter, so that the bottom of the frustum of the second mounting portion is inserted into the rotating hole of the frustum of the first mounting portion.

[0022] In one possible implementation, the base is further provided with a second limiting boss, which is disposed between the first protective door and the second protective door to limit the position of the first protective door and the second protective door when in the closed state.

[0023] Furthermore, the second mounting part is stacked on top of the first mounting part, and the top of the second mounting part is a planar structure. The elastic component is mounted on the planar structure and connected between the first protective door and the second protective door.

[0024] Furthermore, the first and second protective doors rotate around the mounting shaft, the elastic component is a torsion spring, the torsion spring is sleeved on the mounting shaft, and each of the first and second protective doors is provided with a third limiting boss, and the two elastic arms of the torsion spring respectively engage with the third limiting boss for limiting.

[0025] In one possible implementation, the number of elastic components is two, with one elastic component connected between the first protective door and the base, and the other elastic component connected between the second protective door and the base.

[0026] Furthermore, the base is provided with two fourth mounting parts, and the first protective door and the second protective door are respectively provided with third mounting parts. The third mounting parts and the fourth mounting parts are correspondingly arranged. The third mounting parts and the fourth mounting parts are boss structures. Two elastic components are respectively installed on the third mounting parts and the fourth mounting parts on both sides of the first protective door and the second protective door.

[0027] By changing the relationship between the elastic component and the protective door structure, and placing the elastic component on both sides of the protective door, the closing performance of the protective door component is better compared to the embodiment with only one elastic component.

[0028] Furthermore, the base is also provided with at least two fifth limiting protrusions, which are respectively arranged on both sides of the first mounting part and the second mounting part along the second direction, for limiting and protecting the movement of the door component in the second direction.

[0029] Furthermore, the protective door structure of the socket also includes a face cover, which is detachably installed with the base along a third direction. The first protective door, the second protective door, and the elastic component are installed in the face cover and the base to form a protective door module. The face cover is provided with a socket hole for the protective door module to pass through. The protective door module is detachably installed in the socket body.

[0030] By setting the protective door structure of the socket of this application as an integrated protective door module, it can be easily installed and disassembled, greatly improving the installation efficiency during the installation process.

[0031] Furthermore, the socket is a DC socket, and the first and second plug holes are rectangular structures with identical dimensions. The longer side of the first plug hole is in a first direction, and the longer side of the second plug hole is in a second direction. This design allows for compatibility with existing DC plugs, enabling targeted design.

[0032] Compared to existing technologies, this application provides an alternative approach. By rotatably connecting the first and second protective doors, the protective door mechanism is used to shield the socket between the sleeve and the socket hole through rotation, thus protecting the socket from electric shock. The third shielding drive surface of the first protective door and the fourth shielding drive surface of the second protective door abut against each other to form a second drive unit that together shields the second plug hole. When the plug is inserted, the first and second protective doors rotate in opposite directions to avoid the second plug hole. Only half an angle needs to be rotated by the first and second protective doors, which greatly reduces the space occupied by the DC socket protective door and is more conducive to the miniaturization of socket product design.

Detailed Implementation

[0044] The specific implementation of this application is further described below with reference to the accompanying drawings. The scope of protection of this application is not limited to the description of the following embodiments.

[0045] The socket includes a socket body and a protective door structure. The socket body includes multiple socket sleeves with clamping arm structures. One end of each socket sleeve is connected to the power supply of the circuit, and the other end is used to connect to the plug. The socket sleeve has a clamping arm structure, which can cooperate with the plug to achieve a clamping connection, and can fix and limit the plug.

[0046] The protective door structure has a protective door component 100 corresponding to the socket sleeve, which is used to cover the socket sleeve inside the socket when the socket is not in use, so as to prevent small objects from contacting the socket sleeve and causing safety problems.

[0047] like Figure 1 As shown, this application provides a protective door structure for a socket. This protective door structure can be used in both DC and AC sockets. This application uses a DC socket as an example for illustration. Furthermore, to facilitate the reader's understanding of the technical solution of this application, [further details can be added]. Figure 3aIn the diagram, the horizontal direction is defined as the first direction, the vertical direction as the second direction, and the direction perpendicular to the paper (i.e., the thickness direction of the socket) as the third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other.

[0048] It should be noted that the protective door structure of the socket provided in this application can be applied to, but is not limited to, three-hole sockets. For example, it can also be applied to two-hole sockets or other multi-hole sockets. Any socket with similar structural features and the same function as the protective door structure of the socket provided in this application shall fall within the protection scope of this application.

[0049] This application uses a three-hole socket as an example for illustration, wherein, for example... Figure 1 and Figure 2a As shown, the socket hole 103 of the three-hole socket includes a first plug hole 103a, a second plug hole 103b, and a third plug hole 103c. The first plug hole 103a is used to connect the L-pole plug, the second plug hole 103b is used to connect the N-pole plug, and the third plug hole 103c is a grounding hole used to connect a grounding plug for grounding protection. In this embodiment, the third plug hole 103c has a circular structure. Since the third plug hole 103c is used to connect the grounding plug and no current or voltage flows through it, a protective door structure is not required for the third plug hole 103c, thus saving production costs.

[0050] Figure 3a This diagram shows a schematic of the protective door structure of the socket in the present application in an unused state. Figure 5 A schematic diagram of the structure of the base 101 in an embodiment of this application is shown, as follows: Figure 3a and Figure 5 As shown, the protective door structure of the socket provided in this application includes a base 101 and a protective door component 100 installed on the base 101. The protective door component 100 has a closed state and an open state. The base 101 has a ground through hole, an L through hole and an N through hole corresponding to the plug hole 103, which are used to connect and disconnect the power supply of the line by connecting the plug and the socket through the corresponding plug. The protective door component 100 has a long plate-like structure, and each end of the protective door component 100 along its length is provided with a drive part 3 with a groove structure. When the protective door component 100 is in the closed state, the drive part 3 blocks the first plug hole 103a and the second plug hole 103b of the socket, and isolates them from their corresponding sockets, thus providing physical isolation and protection to prevent small objects from accidentally touching the live sockets. When the protective door component 100 is in the open state, the drive part 3 avoids the first plug hole 103a and the second plug hole 103b of the socket, allowing the plug to pass through and be inserted into the socket. In this embodiment, the drive part 3 includes a first drive part 31 and a second drive part 32.

[0051] Figure 1 , Figure 4a and Figure 4b A schematic diagram of the structure of the protective door component 100 in an embodiment of this application is shown, as follows: Figure 1 , Figure 4a and Figure 4b As shown, the protective door component 100 includes a first protective door 1 with a long plate-like structure and a second protective door 2 with a long plate-like structure. Both ends of the first protective door 1 and the second protective door 2 along the length direction are inclined structures. The first protective door 1 is provided with a first mounting part 11 in the middle, and a first blocking driving surface 12 and a third blocking driving surface 13 are respectively provided at both ends. The second protective door 2 is provided with a second mounting part 21 in the middle, and a second blocking driving surface 22 and a fourth blocking driving surface 23 are respectively provided at both ends.

[0052] The first protective door 1 and the second protective door 2 are rotatably connected by the first mounting part 11 and the second mounting part 21. The connection method can be hinged, and the first mounting part 11 and the second mounting part 21 are stacked and have the same rotation center.

[0053] Preferably, the connection between the first mounting part 11 and the second mounting part 21 can be a shaft-hole connection. In this embodiment, the first mounting part 11 has a hole-like structure, and the second mounting part 21 has a shaft-like structure. The first mounting part 11 is sleeved on the second mounting part 21, and the rotatable design is achieved through the cooperation of the shaft and the hole. Of course, the structures of the first mounting part 11 and the second mounting part 21 can be interchanged, that is, the first mounting part 11 has a shaft-like structure, and the second mounting part 21 has a hole-like structure. In another possible implementation, the first mounting part 11 and the second mounting part 21 can both be hole-like structures, and a shaft that cooperates with them is provided on the base 101. The first mounting part 11 and the second mounting part 21 are sleeved on the shaft of the base 101. The first mounting part 11 and the second mounting part 21 can also have various connection structures, which are not listed here. Any structure similar to that of this application and having the same function is within the protection scope of this application.

[0054] like Figure 1 As shown, the protective door structure of the socket also includes an elastic component 4, which is connected between the first protective door 1 and the second protective door 2. The elastic component 4 is used to drive the first protective door 1 and the second protective door 2 to rotate and close, presenting as shown. Figure 3aIn the closed state (i.e., unused state), when the protective door component 100 is closed, the elastic component 4 drives the first protective door 1 and the second protective door 2 to rotate around the rotation center, causing the first blocking drive surface 12 and the second blocking drive surface 13 to abut against each other to form the first drive part 31, and the third blocking drive surface 22 and the fourth blocking drive surface 23 to abut against each other to form the second drive part 32. The first drive part 31 blocks the first plug hole 103a of the socket, and the second drive part 32 blocks the second plug hole 103b of the socket. When the external... When force is applied to the first drive unit 31 and the second drive unit 32, the protective door component 100 switches from the closed state to the open state. The external force drives the first protective door 1 and the second protective door 2 to rotate in opposite directions around the rotation center to the open state (i.e., the use state) of the protective door component 100, causing the first blocking drive surface 12 and the second blocking drive surface 13 to separate and release the obstruction of the first plug hole 103a, and the third blocking drive surface 22 and the fourth blocking drive surface 23 to separate and release the obstruction of the second plug hole 103b. The elastic component 4 can be, but is not limited to, a torsion spring, and can also be a tension spring, compression spring, or other elastic element.

[0055] By configuring the first protective door 1 and the second protective door 2 as rotatably connected, and with the first blocking drive surface 12 of the first protective door 1 and the second blocking drive surface 22 of the second protective door 2 abutting against each other to form a first drive part 31 that together blocks the first plug hole 103a, and the third blocking drive surface 22 of the first protective door 1 and the fourth blocking drive surface 23 of the second protective door 2 abutting against each other to form a second drive part 32 that together blocks the second plug hole 103b, when the plug is inserted, the first protective door 1 and the second protective door 2 only need to rotate a small angle in opposite directions respectively. By avoiding the first plug hole 103a and the second plug hole 103b, the space occupied is small, which can greatly reduce the volume of the protective door component 100, save the internal space of the socket, and thus reduce the size of the socket. The protective door component 100 is set between the socket sleeve and the socket hole, which can prevent small objects from being inserted into the socket hole and contacting the socket sleeve, thus preventing safety problems. This design improves the safety of the socket. At the same time, this structure can be applied to three-hole sockets, two-hole sockets or other multi-hole sockets; it can be applied to DC sockets and AC sockets, and has a wide range of applications.

[0056] Preferred, such as Figure 2b , Figure 3b and Figure 5As shown, the base 101 is also provided with a mounting shaft 61, which is a columnar structure. The first protective door 1 and the second protective door 2 are respectively hinged to the mounting shaft 61 through the first mounting part 11 and the second mounting part 21. When the first driving part 31 and the second driving part 32 respectively block the first plug hole 103a and the second plug hole 103b of the socket, the direction from the first driving part 31 to the second driving part 32 is the first direction, the axial direction of the mounting shaft 61 is the third direction, and the direction perpendicular to the first direction and the third direction is the second direction. That is, the first direction, the second direction and the third direction are perpendicular to each other. In the third direction, the second mounting part 21 of the second protective door 2 is stacked on top of the first mounting part 11 of the first protective door 1. The stacked structure design saves the internal space of the socket, reduces the volume of the socket, and enhances the aesthetics.

[0057] Furthermore, the mounting shaft 61 can be configured such that its cross-sectional length in the second direction is greater than its length in the first direction, so that the mounting shaft 61 abuts against the first mounting part 11 and the second mounting part 21 in the second direction, limiting their movement, while there is a movable gap between it and the second mounting part 21 in the first direction, allowing the first and second protective doors to swing to prevent small objects from being inserted into the first or second plug hole alone. Simultaneously, the first and second mounting parts 11 and 21 can rotate in the second direction in a manner compatible with the mounting shaft 61, ensuring smooth rotation. In one embodiment, the mounting shaft 61 is based on a cylinder, with symmetrical arc-shaped protrusions on both sides of the cylinder along the second direction. These arc-shaped protrusions abut against the mounting shaft 61 in the second direction. Of course, in other embodiments, the structure of the mounting shaft 61 can also be understood as a cylinder with partial cuts on both sides of the cylinder in the first direction; all of these are within the scope of this application.

[0058] Furthermore, such as Figure 2b and Figure 3a As shown, when the protective door component 100 is in the closed state, and the first drive part 31 and the second drive part 32 respectively block the first plug hole 103a and the second plug hole 103b of the socket, there is a gap between the mounting shaft 61 and the first mounting part 11 and the second mounting part 21 in the first direction, and there is a gap between the first drive part 31 and the second drive part 32 and the base 101 in the third direction; when the external force is applied only to the first drive part 31 or the second drive part 32, the first protective door 1 and the second protective door 2 tilt towards the base 101 in the third direction. When one end of them is close to the base 101, that end is limited by the single-insertion limiting structure in the base 101, so that the first protective door 1 and the second protective door 2 cannot rotate.

[0059] By setting a single-insertion limiting structure on the base 101, single-pole insertion can be prevented. When a single pole is inserted, one end of the protective door component 100 is tilted by force. This end contacts the base 101 and is limited by the single-insertion limiting structure on the base 101, preventing the protective door component 100 from rotating open from the closed state. Only when the two pole plugs drive the driving parts 3 at both ends of the protective door component 100 at the same time will the first protective door 1 and the second protective door 2 rotate open in opposite directions, releasing the obstruction of the driving part 3 on the first plug hole 103a and the second plug hole 103b.

[0060] Furthermore, such as Figure 2b , Figure 3a , Figure 4b and Figure 5 As shown, the single-insertion limiting structure may include a plurality of first limiting protrusions 51 disposed on the base 101. When the first driving part 31 and the second driving part 32 respectively block the first plug hole 103a and the second plug hole 103b of the socket, at least one first limiting protrusion 51 is disposed on each side of the lower gap between the two ends of the first protective door 1 and the second protective door 2. When an external force is applied to the first driving part 31 or the second driving part 32, when one end of the protective door component 100 abuts against the base 101, the end is placed inside the first limiting protrusions 51 on both sides and is limited by them, so that the first protective door 1 and the second protective door 2 cannot rotate in opposite directions.

[0061] With a gap between the mounting shaft 61 and the first mounting part 11 and the second mounting part 21 in the first direction, and a gap between the first driving part 31 and the second driving part 32 and the base 101 in the third direction, when one end of the first driving part 31 or the second driving part 32 is subjected to force, that end will tilt toward the base 101. By setting a single-insertion limiting structure to limit the tilted end, the first protective door 1 and the second protective door 2 are prevented from rotating in opposite directions, so that the driving part 3 continues to shield and protect the first plug hole 103a and the second plug hole 103b. This can improve the safety of the socket during use and prevent small objects from being inserted into the socket, thus preventing safety hazards.

[0062] As another embodiment, the single-insertion limiting structure can also be a limiting groove provided on the side of the first protective door 1 and the second protective door 2 facing the base 101, and a plurality of sixth limiting protrusions provided on the base 101. When the first driving part 31 and the second driving part 32 respectively block the first plug hole 103a and the second plug hole 103b of the socket, the limiting groove corresponds to the sixth limiting protrusion. When an external force is applied to the first driving part 31 or the second driving part 32, one end of the first protective door 1 and the second protective door 2 tilts towards the base 101, and the limiting groove at that end fits onto the sixth limiting protrusion to achieve a locking fit, so that the first protective door 1 and the second protective door 2 cannot rotate in opposite directions.

[0063] It is obvious that there are many ways to implement a single-insertion limiting structure, which will not be elaborated here. Any ideas that can be conceived by those skilled in the art in combination with the prior art are within the scope of protection of this application.

[0064] Preferred, such as Figure 3a , Figure 4a and Figure 4b As shown, the first protective door 1 includes two first blocking rods respectively connected to the radial sides of the first mounting part 11. The ends of the two first blocking rods are respectively provided with a first blocking driving surface 12 and a third blocking driving surface 13. The second protective door 2 includes two second blocking rods respectively connected to the radial sides of the second mounting part 21. The ends of the two second blocking rods are respectively provided with a second blocking driving surface 22 and a fourth blocking driving surface 23. The first blocking driving surface 12, the second blocking driving surface 22, the third blocking driving surface 13 and the fourth blocking driving surface 23 are all inclined surfaces. When the first blocking driving surface 12 and the second blocking driving surface 22 abut against each other, a first driving part 31 with a V-shaped groove is formed. When the third blocking driving surface 13 and the fourth blocking driving surface 23 abut against each other, a second driving part 32 with a V-shaped groove is formed. By setting the first shielding drive surface 12, the second shielding drive surface 22, the third shielding drive surface 13 and the fourth shielding drive surface 23 as inclined structures, the first protective door 1 and the second protective door 2 can generate forces that rotate in opposite directions, driving the first protective door 1 and the second protective door 2 to rotate.

[0065] In other embodiments, the first blocking driving surface 12, the second blocking driving surface 22, the third blocking driving surface 13 and the fourth blocking driving surface 23 are not strictly inclined surfaces, but have a sloped structure, which can also achieve the same technical effect. For example, they may also be curved surfaces. In this case, the first driving part 31 and the second driving part 32 will not be strictly V-grooves, which are all within the protection scope of this application.

[0066] Furthermore, such as Figure 2b , Figure 3a , Figure 4a and Figure 4b As shown, the first mounting portion 11 of the first protective door 1 and the second mounting portion 21 of the second protective door 2 are both hollow structures with rotating holes. The hollow structure is frustum-shaped, and the bottom diameter of the frustum-shaped structure of the second mounting portion 21 is smaller than the top diameter. The bottom of the frustum-shaped structure of the second mounting portion 21 can be inserted into the rotating hole of the frustum-shaped structure of the first mounting portion 11. By setting the frustum-shaped structure of the second mounting portion 21 to have a bottom diameter smaller than the top diameter, a gap exists between the mounting shaft 61 and the second mounting portion 21 in the first direction, and this gap gradually increases from the bottom of the base outward in the third direction. This gap allows the protective door component 100 to be in the closed state, so that when the first driving portion 31 or the second driving portion 32 is subjected to force, the force-bearing end can move closer to the base 101.

[0067] Preferred, such as Figure 3b and Figure 5 As shown, the base 101 is also provided with a second limiting boss 52, which is disposed between the first protective door 1 and the second protective door 2, limiting the position of the first protective door 1 and the second protective door 2 in the closed state, so that the closed surface is in the first direction in the closed state. This design can ensure that the driving parts 3 at both ends of the protective door component 100 completely cover the corresponding side of the socket, ensuring that the corresponding position is reasonable and convenient for the plug to be inserted into the socket.

[0068] Preferred, such as Figure 3a and Figure 4b As shown, the second mounting part 21 is stacked on top of the first mounting part 11. The top of the second mounting part 21 is a planar structure. The elastic member 4 is mounted on the planar structure and connected between the first protective door 1 and the second protective door 2.

[0069] Furthermore, such as Figure 3a , Figure 4a and Figure 4b As shown, the first protective door 1 and the second protective door 2 rotate around the mounting shaft 61. The elastic component 4 is a torsion spring, which is sleeved on the mounting shaft 61. Each of the first protective door 1 and the second protective door 2 is provided with a third limiting boss 53. The two elastic arms of the torsion spring respectively engage with the third limiting boss 53 to limit and fix the torsion spring. Furthermore, to make the torsion spring installation more secure, additional features can be provided on the planar structure, such as... Figure 4b The fourth limiting boss 54 is shown.

[0070] Preferred, such as Figure 6a and Figure 6b As shown, in another embodiment where the protective door structure cooperates with the elastic component 4, there are two elastic components 4. One elastic component 4 is connected between the first protective door 1 and the base 101, and the other elastic component 4 is connected between the second protective door 2 and the base 101. In some other embodiments, the number of elastic components 4 is not limited to two or more; for example, there can be four, respectively disposed on both sides of the protective door component 100. Specifically, the design is based on actual needs and will not be elaborated further.

[0071] Furthermore, such as Figure 6a and Figure 6bAs shown, the first protective door 1 and the second protective door 2 are each provided with a third mounting part 71, and the base 101 is provided with two fourth mounting parts 72. The third mounting parts 71 and the fourth mounting parts 72 are correspondingly arranged. The third mounting parts 71 and the fourth mounting parts 72 are boss structures, and two elastic members 4 are respectively installed on the third mounting parts 71 and the fourth mounting parts 72 on both sides of the first protective door 1 and the second protective door 2. Of course, in some other embodiments, the third mounting parts 71 and the fourth mounting parts 72 can also be groove structures, and the elastic members 4 are embedded in the groove structure to achieve a fixing effect. Of course, the third mounting parts 71 and the fourth mounting parts 72 can also be a combination of boss structures and groove structures. Any structural design that can achieve the same fixing effect is included in the protection scope of this application.

[0072] In this embodiment, by changing the cooperation relationship between the elastic component 4 and the protective door structure, the elastic component 4 is disposed on both sides of the protective door. Compared with the embodiment that only has one elastic component 4, the closing performance of the protective door component 100 is better. In a preferred embodiment, the third mounting portion 71 and the fourth mounting portion 72 on both sides of the first protective door 1 and the second protective door 2 are symmetrical with respect to the closing surface of the protective door component 100 in the first direction. Through the symmetrical structural design, the first protective door 1 and the second protective door 2 can be subjected to uniform force during rotation, thereby obtaining a better closing effect.

[0073] Furthermore, such as Figure 3a and Figure 5 As shown, at least two fifth limiting protrusions 55 may also be provided on the base 101, and are respectively provided on both sides of the first mounting part 11 and the second mounting part 21 along the second direction, for limiting and protecting the movement of the door component 100 in the second direction to prevent it from shaking during use.

[0074] Furthermore, such as Figure 1 As shown, the protective door structure of the socket in this application may further include a face cover 102. The face cover 102 and the base 101 are detachably installed along a third direction. The first protective door 1, the second protective door 2, and the elastic component 4 are installed in the face cover 102 and the base 101 to form a protective door module. The face cover 102 is provided with insertion holes (i.e., the first plug hole 103a, the second plug hole 103b, and the third plug hole 103c) for the plug to pass through the protective door module. The protective door module is detachably installed in the socket body. By setting the protective door structure of the socket in this application as an integrated protective door module, it is convenient to install and disassemble, and the installation efficiency is greatly improved during the installation process.

[0075] In another possible implementation, the protective door structure of the socket can also be a modular structure, installed separately inside the socket. In this case, the base 101 can serve as a partition between the protective door structure and the socket body, and the cover 102 is the socket panel. During the socket installation process, the various parts of the protective door structure are installed separately on the partition, thereby shielding and protecting the socket socket, preventing small objects from contacting the socket socket and causing electric shock accidents. Figure 1 The base 101 and the cover 102 can be understood as the housing of the protective door module or as part of the socket, and both fall within the scope of protection of this application.

[0076] Furthermore, such as Figure 2a As shown, when the protective door structure of the socket in this application is used as a DC socket, the first plug hole 103a and the second plug hole 103b can be rectangular structures with the same structure, and the long side of the first plug hole 103a is in a first direction, while the long side of the second plug hole 103b is in a second direction. By setting the first plug hole 103a and the second plug hole 103b as rectangular structures in different directions, it can be used with DC plugs in the prior art, achieving a targeted design. In particular, the protective door component 100 of this embodiment is especially suitable for DC sockets, for example... Figure 2a The second plug hole 103b has a relatively large length in the second direction. If only one of the blocking drive surfaces on the rotating first protective door 1 or the second protective door 2 is used to block it, the first protective door 1 or the second protective door 2 needs to rotate a large angle to avoid the second plug hole 103b, which requires a large amount of space. However, in this embodiment, the third blocking drive surface 22 of the first protective door 1 and the fourth blocking drive surface 23 of the second protective door 2 abut against each other to form the second drive part 32, which together blocks the second plug hole 103b. When the plug is inserted, the first protective door 1 and the second protective door 2 rotate in opposite directions to avoid the second plug hole 103b. Only half an angle needs to be rotated by the first protective door 1 and the second protective door 2, which greatly reduces the space occupied by the DC socket protective door.

[0077] Of course, the protective door structure of the socket provided in this application can be designed in other ways according to the existing plug types. When used with an AC plug, the structure of the first plug hole 103a and the second plug hole 103b and their corresponding drive part 3 can be changed accordingly. For example, the first plug hole 103a and the second plug hole 103b can be not rectangular, but circular or square. Of course, based on the change of the plug hole, the structure of its corresponding drive part 3 can also be adjusted accordingly.

[0078] Furthermore, such as Figure 2aAs shown, when the protective door component 100 is in the closed state, the closing surfaces of the first protective door 1 and the second protective door 2 along the second direction can respectively cut the first plug hole 103a and the second plug hole 103b into symmetrical structures. This design allows the driving parts 3 at both ends of the protective door component 100 to be subjected to uniform force, improving the sensitivity of the socket protective door component 100.

[0079] Compared to existing technologies, this application provides an alternative approach. By rotatably connecting the first and second protective doors, the protective door mechanism is used to shield the socket between the socket sleeve and the socket hole through rotation, thus providing electric shock protection for the socket sleeve. This fully utilizes the product space, reduces the size of the socket, and is more conducive to the miniaturization of socket product design.
