Description

Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a protective door structure of a socket Background Art

[0002] A socket is an electronic device used to provide electrical energy to a plug, which mainly includes a shell and a socket. The pins of the plug pass through the panel of the shell to be inserted into the shell, thereby contacting the socket and obtaining electricity. In the related art, in order to prevent users from inserting metal objects into the socket and causing electric shock accidents, a protective door structure is configured in the socket, and the protective door structure is located between the panel and the socket. When there is no plug connected, the protective door structure can block the socket on the panel. When the plug is inserted, the pins of the plug will push open the protective door structure, release the blocking of the socket by the protective door structure, and thus allow the pins of the plug to be smoothly inserted. However, due to the need to provide moving space for the linear movement of the protective door structure, it is not easy to achieve a miniaturized design for the socket. Utility Model Content

[0003] The utility model aims to overcome the defects of the prior art and provide a space-saving and rotatable socket protection door structure.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model provides a protection door structure of a socket, comprising a protection door component and an elastic component installed on a base, wherein the protection door component comprises a first protection door and a second protection door.

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

[0007] The first protection door and the second protection door are hinged through a first mounting portion and a second mounting portion, and the first mounting portion and the second mounting portion are stacked and have the same rotation center;

[0008] When the protective door components are in a closed state, the elastic component drives the first protective door and the second protective door to rotate around the rotation center, so that the first shielding driving surface and the second shielding driving surface abut against each other to form a first driving part, and the third shielding driving surface and the fourth shielding driving surface abut against each other to form a second driving part;

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

[0010] When an external force acts on the first driving part and the second driving part, the protection door component switches from the closed state to the open state. The external force drives the first protection door and the second protection door to rotate in opposite directions around the rotation center, so that the first occlusion driving surface and the second occlusion driving surface are separated and the occlusion of the first plug hole is released, and the third occlusion driving surface and the fourth occlusion driving surface are separated and the occlusion of the second plug hole is released.

[0011] By setting the first protection door and the second protection door to be rotatably connected, and the first occlusion driving surface of the first protection door and the second occlusion driving surface of the second protection door abut against each other to form the first driving part to occlude the first plug hole together, and the third occlusion driving surface of the first protection door and the fourth occlusion driving surface of the second protection door abut against each other to form the second driving part to occlude the second plug hole together. When the plug is inserted, the first protection door and the second protection door only need to rotate a small angle in opposite directions respectively to avoid the first plug hole and the second plug hole, which occupies a small space, can greatly reduce the volume of the protection door component, save the internal space of the socket, and further reduce the volume of the socket, realizing the small and beautiful appearance of the socket; The protection door component is arranged between the socket sleeve and the socket hole, which can prevent small objects from being inserted into the socket hole to contact the socket sleeve and cause safety problems. This design improves the safety of the socket. At the same time, this structure can be applied to both three-hole sockets and two-hole sockets or other multi-hole sockets; It can be applied to both DC sockets and AC sockets, and has a wide range of applications.

[0012] In a possible implementation manner, an installation shaft is further arranged on the base, and the first installation part and the second installation part are installed on the installation shaft, so that the first protection door and the second protection door are hinged on the installation shaft;

[0013] When the first driving part and the second driving part respectively occlude the first plug hole and the second plug hole of the socket, the direction from the first driving part to the second driving part is the first direction, the axial direction of the installation 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 installation part of the second protection door is stacked above the first installation part of the first protection door.

[0014] By arranging the installation shaft on the base, the first protection door and the second protection door are rotationally installed on the installation shaft through the first installation part and the second installation part, which can realize the fixed installation of the protection door component and the base. At the same time, in the third direction, the second installation part of the second protection door is stacked above the first installation part of the first protection door, which can reduce the volume of the protection door, save the internal space of the socket, and further reduce the volume of the socket, realizing the small and beautiful appearance of the socket.

[0015] Further, 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 an external force acts only on the first driving part or the second driving part, the first protection door and the second protection door tilt in the third direction towards the direction close to the base and are limited by the single-plug limiting structure in the base, so that the first protection door and the second protection door cannot rotate.

[0016] Further, the single-plug limiting structure includes a plurality of first limiting bosses arranged 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 boss is arranged on each side of the gap below both ends of the first protection door and the second protection door. When an external force acts on the first driving part or the second driving part to make one end of the protection door component abut against the base, this end is placed within the first limiting bosses on both sides, so that the first protection door and the second protection door cannot rotate in the opposite direction.

[0017] By having a gap between the mounting shaft and the first mounting part and the second mounting part in the first direction, and a gap between the first driving part and the second driving part and the base in the third direction, when one end of the first driving part or the second driving part is stressed, this end deflects towards the base direction, and by arranging the single-plug limiting structure to limit the deflected end, preventing the first protection door and the second protection door from rotating in the opposite direction, enabling the driving part to continue to block and protect the first plug hole and the second plug hole, the safety of the socket during use can be improved, preventing small objects from being inserted into the socket through the first plug hole or the second plug hole alone, thus generating potential safety hazards.

[0018] Further, the first mounting part and the second mounting part abut against the mounting shaft in the second direction to limit it in the second direction. On the basis that there is a gap between the first mounting part and the second mounting part and the mounting shaft in the first direction and they can swing, at the same time, the first mounting part and the second mounting part can rotate in a manner adapted to the mounting shaft in the second direction, ensuring the smoothness of rotation.

[0019] In a possible implementation manner, the first protection door includes two first blocking rods respectively connected to the two radial sides of the first mounting part. The ends of the two first blocking rods are respectively provided with the first blocking driving surface and the third blocking driving surface. The second protection door includes two second blocking rods respectively connected to the two radial sides of the second mounting part. The ends of the two second blocking rods are respectively provided with the second blocking driving surface and the 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 when the first blocking driving surface abuts against the second blocking driving surface, a first driving part in the shape of a V-shaped groove is formed, and when the third blocking driving surface abuts against the fourth blocking driving surface, a second driving part in the shape of a V-shaped groove is formed.

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

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

[0022] In a possible implementation manner, a second limiting boss is further provided on the base. The second limiting boss is arranged between the first protection door and the second protection door to limit the positions of the first protection door and the second protection door in the closed state.

[0023] Furthermore, the second mounting portion is stacked above the first mounting portion. The top of the second mounting portion is a planar structure. The elastic member is mounted on the planar structure and is connected between the first protection door and the second protection door.

[0024] Furthermore, the first protection door and the second protection door rotate around the mounting shaft. The elastic member is a torsion spring. The torsion spring is sleeved on the mounting shaft. Third limiting bosses are respectively provided on the first protection door and the second protection door. The two elastic arms of the torsion spring are respectively in limiting cooperation with the third limiting bosses.

[0025] In a possible implementation manner, the number of the elastic members is two. One elastic member is connected between the first protection door and the base, and the other elastic member is connected between the second protection door and the base.

[0026] Furthermore, two fourth mounting portions are provided on the base. The first protection door and the second protection door are respectively provided with third mounting portions. The third mounting portions and the fourth mounting portions are arranged corresponding to each other. The third mounting portions and the fourth mounting portions are boss structures. The two elastic members are respectively mounted on the third mounting portions and the fourth mounting portions on both sides of the first protection door and the second protection door.

[0027] By changing the cooperation relationship between the elastic member and the protection door structure and arranging the elastic member on both sides of the protection door, the closing property of the protection door component will be better compared with the embodiment in which one elastic member is provided.

[0028] Furthermore, at least two fifth limiting bosses are provided on the base, and are respectively arranged on both sides of the first mounting portion and the second mounting portion along the second direction, for limiting the movement of the protection door component in the second direction.

[0029] Furthermore, the protection door structure of the socket further includes a face cover, the face cover is detachably mounted on the base along the third direction, the first protection door, the second protection door, and the elastic component are installed in the face cover and the base to form a protection door module, the face cover is provided with a jack for the plug to pass through the protection door module, and the protection door module is detachably mounted in the socket body.

[0030] By setting the protection door structure of the socket of the present application as an integrated protection door module, it is convenient for installation and disassembly, and the installation efficiency is greatly improved during the installation process.

[0031] Furthermore, the socket is a DC socket, the first plug hole and the second plug hole are rectangular structures with the same structure, and the long side of the first plug hole is in the first direction, and the long side of the second plug hole is in the second direction. Through this design, it can be used in cooperation with the DC plug in the prior art to achieve a targeted design.

[0032] Compared with the prior art, the present application provides another idea. By rotatably connecting the first protection door and the second protection door, the protection door mechanism is used to block between the socket and the jack in a rotating manner to provide anti-electric shock protection for the socket of the socket. The third blocking driving surface of the first protection door and the fourth blocking driving surface of the second protection door abut against each other to form a second driving part to block the second plug hole together. When the plug is inserted, the first protection door and the second protection door rotate in opposite directions to avoid the second plug hole respectively, and only need to rotate half of the angle of each of the first protection door and the second protection door, which greatly reduces the space occupied by the protection door of the DC socket and is more conducive to the miniaturization of the socket product design.

Detailed implementation manners

[0044] The following embodiments given in conjunction with the accompanying drawings further illustrate the specific implementation manners of the present application. The protection scope of the present application is not limited to the descriptions of the following embodiments.

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

[0046] The protection door structure has a protection door component 100 corresponding to the socket sleeve, which is used to shield the socket sleeve in the socket when the socket is not in use, preventing small objects from contacting the socket sleeve and causing safety problems.

[0047] As Figure 1 shown, the present application provides a protection door structure for a socket. This protection door structure of the socket can be used in both DC sockets and AC sockets. The present application takes a DC socket as an example for illustration. In addition, for the convenience of the reader to understand the technical solution of the present application, Figure 3aIn it, the horizontal direction is defined as the first direction, the vertical direction is defined as the second direction, and the direction perpendicular to the paper surface (i.e., the socket thickness direction) is defined as the third direction, where the first direction, the second direction, and the third direction are perpendicular to each other.

[0048] It should be noted that the protection door structure of the socket provided in this application can be but is not limited to being applied to a three-hole socket. For example, it can also be applied to a two-hole socket or other multi-hole sockets. As long as it has a similar structural feature and the same function as the protection door structure of the socket provided in this application, it belongs to the protection scope of this application.

[0049] This application takes a three-hole socket as an example for illustration. Among them, as Figure 1 and Figure 2a shown, the socket holes 103 of the three-hole socket include 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 ground pole jack for connecting a grounding plug to perform grounding protection. In the embodiment of this application, the third plug hole 103c is a circular structure. Since no current or voltage flows through the third plug hole 103c for connecting the grounding plug, a protection door structure is not provided for the third plug hole 103c, thus saving production costs.

[0050] Figure 3a shows a schematic structural diagram of the protection door structure of the socket of this application in an unused state. Figure 5 shows a schematic structural diagram of the base 101 in the embodiment of this application. As Figure 3a and Figure 5 shown, the protection door structure of the socket provided in this application includes a base 101 and a protection door component 100 installed on the base 101. The protection door component 100 has a closed state and an open state. The base 101 has a ground pole through hole, an L-pole through hole, and an N-pole through hole corresponding to the plug hole 103 for passing through the corresponding plugs. The plug is inserted and mated with the socket to realize the connection and disconnection of the line power supply. The protection door component 100 is a long plate-like structure, and driving parts 3 with groove structures are respectively arranged at both ends of the protection door component 100 along the length direction. When the protection door component 100 is in the closed state, the driving parts 3 block the first plug hole 103a and the second plug hole 103b of the socket, blocking between the first plug hole 103a and the second plug hole 103b and their corresponding socket sleeves for physical isolation protection to prevent small objects from accidentally touching the live socket sleeves. When the protection door component 100 is in the open state, the driving parts 3 avoid 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 jack in the socket. Among them, in the embodiment of this application, the driving part 3 includes a first driving part 31 and a second driving part 32.

[0051] Figure 1 , Figure 4a and Figure 4b show a schematic structural view of the protection door component 100 in an embodiment of the present application. As Figure 1 , Figure 4a and Figure 4b shown, the protection door component 100 includes a first protection door 1 with a long plate-like structure and a second protection door 2 with a long plate-like structure. Both ends of the first protection door 1 and the second protection door 2 in the length direction are bevel structures. A first installation part 11 is provided in the middle of the first protection door 1, and a first shielding driving surface 12 and a third shielding driving surface 13 are respectively provided at both ends; a second installation part 21 is provided in the middle of the second protection door 2, and a second shielding driving surface 22 and a fourth shielding driving surface 23 are respectively provided at both ends.

[0052] The first protection door 1 and the second protection door 2 are rotatably connected through the first installation part 11 and the second installation part 21. Among them, the connection method can be hinged, and the first installation part 11 and the second installation part 21 are stacked and have the same rotation center.

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

[0054] As Figure 1 shown, the protection door structure of the socket further includes an elastic member 4. The elastic member 4 is connected between the first protection door 1 and the second protection door 2. The elastic member 4 is used to drive the first protection door 1 and the second protection door 2 to rotate and close to present as Figure 3aThe closed state (i.e., the unused state) is shown. In the closed state of the protection door component 100, the elastic component 4 drives the first protection door 1 and the second protection door 2 to rotate around the rotation center, so that the first shielding driving surface 12 and the second shielding driving surface 22 are abutted against each other to form the first driving part 31, and the third shielding driving surface 13 and the fourth shielding driving surface 23 are abutted against each other to form the second driving part 32. The first driving part 31 shields the first plug hole 103a of the socket, and the second driving part 32 shields the second plug hole 103b of the socket. When an external force acts on the first driving part 31 and the second driving part 32, the protection door component 100 is switched from the closed state to the open state. The external force drives the first protection door 1 and the second protection door 2 to rotate around the rotation center in opposite directions to the open state (i.e., the use state) of the protection door component 100, so that the first shielding driving surface 12 and the second shielding driving surface 22 are separated and the shielding of the first plug hole 103a is released, and the third shielding driving surface 13 and the fourth shielding driving surface 23 are separated and the shielding of the second plug hole 103b is released. Among them, the elastic component 4 can be but is not limited to a torsion spring. For example, it can also be a tension spring, a compression spring, or other elastic components.

[0055] By setting the first protection door 1 and the second protection door 2 to be rotatably connected, and the first shielding driving surface 12 of the first protection door 1 and the second shielding driving surface 22 of the second protection door 2 are abutted against each other to form the first driving part 31 to shield the first plug hole 103a together, and the third shielding driving surface 13 of the first protection door 1 and the fourth shielding driving surface 23 of the second protection door 2 are abutted against each other to form the second driving part 32 to shield the second plug hole 103b together. When the plug is inserted, the first protection door 1 and the second protection door 2 only need to rotate a very small angle in opposite directions respectively to avoid the first plug hole 103a and the second plug hole 103b. The occupied space is small, the volume of the protection door component 100 can be greatly reduced, the internal space of the socket can be saved, and then the volume of the socket is reduced. The protection door component 100 is arranged between the socket sleeve and the socket hole, which can prevent small objects from being inserted into the socket hole to contact the socket sleeve, resulting in safety problems. This design improves the safety of the socket. At the same time, this structure can be applied to both three-hole sockets and two-hole sockets or other multi-hole sockets; it can be applied to both DC sockets and AC sockets, and has a wide range of applications.

[0056] Preferably, as Figure 2b 、 Figure 3b and Figure 5As shown, an installation shaft 61 is further provided on the base 101. The installation shaft 61 is of a columnar structure. The first protection door 1 and the second protection door 2 are respectively hinged to the installation shaft 61 through a first installation part 11 and a second installation 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 installation 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 installation part 21 of the second protection door 2 is stacked above the first installation part 11 of the first protection door 1. Through the stacked structural design, the internal space of the socket is saved, the volume of the socket is reduced, and the aesthetics is enhanced.

[0057] Further, the installation shaft 61 can be set such that the length of its cross-section in the second direction is greater than the length in the first direction, so that the installation shaft 61 abuts against the first installation part 11 and the second installation part 21 in the second direction to limit them, and there is a movable gap between the installation shaft 61 and the second installation part 21 in the first direction, so that the first protection door and the second protection door can swing to prevent small objects from being inserted into the first plug hole or the second plug hole alone. At the same time, the first installation part 11 and the second installation part 21 can rotate adaptively with the installation shaft 61 in the second direction to ensure the smoothness of rotation. In one embodiment, the installation shaft 61 is based on a cylinder, and arc-shaped protrusions with symmetric structures are provided on both sides of the cylinder along the second direction. The arc-shaped protrusions abut against the installation shaft 61 in the second direction. Of course, in other embodiments, the structure of the installation shaft 61 can also be understood as partially intercepting both sides of the cylinder in the first direction. This is all within the protection scope of this application.

[0058] Further, as Figure 2b and Figure 3a shown, when the protection door component 100 is in a closed state and 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, there is a gap between the installation shaft 61 and the first installation part 11 and the second installation part 21 in the first direction, and there is a gap between the first driving part 31 and the second driving part 32 and the base 101 in the third direction; when an external force acts only on the first driving part 31 or the second driving part 32, the first protection door 1 and the second protection door 2 tilt in the third direction towards the direction close to the base 101. When one end of them is close to the base 101, this end is limited by the single-plug limiting structure in the base 101, so that the first protection door 1 and the second protection door 2 cannot rotate.

[0059] By setting a single-pole insertion limiting structure on the base 101, single-pole insertion prevention can be achieved. When a single-pole is inserted, one end of the protection door component 100 is stressed and tilted, and this end contacts the base 101 and is limited by the single-pole insertion limiting structure on the base 101, preventing the protection door component 100 from rotating and opening from the closed state. Only when the two-pole plug simultaneously drives the driving parts 3 at both ends of the protection door component 100, will the first protection door 1 and the second protection door 2 rotate and open in opposite directions, removing the shielding of the driving parts 3 from the first plug hole 103a and the second plug hole 103b.

[0060] Further, as Figure 2b 、 Figure 3a 、 Figure 4b and Figure 5 shown, the single-pole insertion limiting structure may include a plurality of first limiting bosses 51 provided on the base 101. When the first driving part 31 and the second driving part 32 respectively shield the first plug hole 103a and the second plug hole 103b of the socket, at least one first limiting boss 51 is provided on each side of the lower gap at both ends of the first protection door 1 and the second protection door 2. When an external force acts on the first driving part 31 or the second driving part 32 and one end of the protection door component 100 abuts against the base 101, this end is placed within the first limiting bosses 51 on both sides and is limited by them, preventing the first protection door 1 and the second protection door 2 from rotating in opposite directions.

[0061] Due to the gap between the mounting shaft 61 and the first mounting part 11 and the second mounting part 21 in the first direction, and the 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 stressed, this end will deflect towards the base 101. By setting the single-pole insertion limiting structure to limit the deflected end, the first protection door 1 and the second protection door 2 are prevented from rotating in opposite directions, enabling the driving part 3 to continue shielding the first plug hole 103a and the second plug hole 103b, improving the safety during the use of the socket and preventing small objects from being inserted into the socket, thus eliminating potential safety hazards.

[0062] As another embodiment, the single-pole insertion limiting structure may also be a limiting groove provided on the surfaces of both ends of the first protection door 1 and the second protection door 2 facing the base 101, and a plurality of sixth limiting bosses provided on the base 101. When the first driving part 31 and the second driving part 32 respectively shield the first plug hole 103a and the second plug hole 103b of the socket, the limiting groove corresponds to the sixth limiting boss. When an external force acts on the first driving part 31 or the second driving part 32, one end of the first protection door 1 and the second protection door 2 tilts towards the base 101, and the limiting groove at this end is sleeved on the sixth limiting boss to achieve mating and locking, preventing the first protection door 1 and the second protection door 2 from rotating in opposite directions.

[0063] Obviously, there are various implementation manners for the single-insert limit structure, which will not be elaborated here. Whatever can be conceived by those skilled in the art by combining the revelations of the prior art belongs to the protection scope of this application.

[0064] Preferably, as Figure 3a , Figure 4a and Figure 4b shown, the first protection door 1 includes two first shielding rods respectively connected to two radial sides of the first mounting portion 11. The end portions of the two first shielding rods are respectively provided with the first shielding driving surface 12 and the third shielding driving surface 13. The second protection door 2 includes two second shielding rods respectively connected to two radial sides of the second mounting portion 21. The end portions of the two second shielding rods are respectively provided with the second shielding driving surface 22 and the fourth shielding driving surface 23. The first shielding driving surface 12, the second shielding driving surface 22, the third shielding driving surface 13 and the fourth shielding driving surface 23 are all inclined surfaces. When the first shielding driving surface 12 abuts against the second shielding driving surface 22, a first driving portion 31 of a V-shaped groove is formed. When the third shielding driving surface 13 abuts against the fourth shielding driving surface 23, a second driving portion 32 of a V-shaped groove is formed. By setting the first shielding driving surface 12, the second shielding driving surface 22, the third shielding driving surface 13 and the fourth shielding driving surface 23 as inclined surface structures, forces in opposite directions can be generated on the first protection door 1 and the second protection door 2 to drive the first protection door 1 and the second protection door 2 to rotate.

[0065] In other embodiments, the first shielding driving surface 12, the second shielding driving surface 22, the third shielding driving surface 13 and the fourth shielding driving surface 23 are not strictly inclined surfaces but have a slope-like structure, and the same technical effects can also be achieved. For example, they may also be arc-shaped surfaces. In this case, the first driving portion 31 and the second driving portion 32 will not be strictly V-shaped grooves either. All of these belong to the protection scope of this application.

[0066] Furthermore, as Figure 2b , Figure 3a , Figure 4a and Figure 4b shown, the first mounting portion 11 of the first protection door 1 and the second mounting portion 21 of the second protection door 2 are both hollow structures provided with rotation holes. The hollow structure has a frustum shape. 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 rotation 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 outward from the bottom of the base along the third direction. This gap enables, when the first driving portion 31 or the second driving portion 32 is stressed in the closed state of the protection door assembly 100, the stressed end to approach the base 101.

[0067] Preferably, as Figure 3b and Figure 5 shown, a second limiting boss 52 is further provided on the base 101. The second limiting boss 52 is disposed between the first protection door 1 and the second protection door 2 to define the positions of the first protection door 1 and the second protection door 2 in the closed state, so that in the closed state, the closing surface is in the first direction. Such a design can ensure that the driving parts 3 at both ends of the protection door component 100 completely cover the jacks on their corresponding sides, ensuring that the corresponding positions are reasonable and facilitating the insertion of the plug into the jack.

[0068] Preferably, as Figure 3a and Figure 4b shown, the second mounting portion 21 is stacked above the first mounting portion 11. The top of the second mounting portion 21 is a planar structure, and the elastic member 4 is mounted on the planar structure and connected between the first protection door 1 and the second protection door 2.

[0069] Furthermore, as Figure 3a , Figure 4a and Figure 4b shown, the first protection door 1 and the second protection door 2 rotate around the mounting shaft 61. The elastic member 4 is a torsion spring, and the torsion spring is sleeved on the mounting shaft 61. Third limiting bosses 53 are respectively provided on the first protection door 1 and the second protection door 2, and the two elastic arms of the torsion spring are respectively in limiting cooperation with the third limiting bosses 53 to fix the torsion spring. In addition, in order to make the installation of the torsion spring more firm, a fourth limiting boss 54 as shown in Figure 4b can also be provided on the planar structure.

[0070] Preferably, as Figure 6a and Figure 6b shown, in another embodiment of the cooperation between the protection door structure and the elastic member 4, the number of the elastic members 4 is two. One elastic member 4 is connected between the first protection door 1 and the base 101, and the other elastic member 4 is connected between the second protection door 2 and the base 101. In some other embodiments, the number of the elastic members 4 is not limited to two or more. For example, it can also be four, which are respectively disposed on both sides of the protection door component 100. Specifically, it is designed according to actual needs and will not be elaborated here.

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

[0072] In this embodiment, by changing the cooperation relationship between the elastic component 4 and the protection door structure, the elastic component 4 is arranged on both sides of the protection door. Compared with the embodiment in which one elastic component 4 is arranged, the closing property of the protection door component 100 will be better. In a preferred embodiment, the third mounting parts 71 and the fourth mounting parts 72 on both sides of the first protection door 1 and the second protection door 2 are symmetrical with respect to the closing surface of the protection door component 100 in the first direction. Through the symmetrical structural design, the first protection door 1 and the second protection door 2 can be evenly stressed during the rotation process, and a better closing effect can be obtained.

[0073] Furthermore, as Figure 3a and Figure 5 shown, at least two fifth limiting bosses 55 can also be arranged on the base 101, and are respectively arranged on both sides of the first mounting part 11 and the second mounting part 21 along the second direction, so as to limit the movement of the protection door component 100 in the second direction and prevent it from shaking during use.

[0074] Furthermore, as Figure 1 shown, the protection door structure of the socket of this application can also include a face cover 102. The face cover 102 is detachably mounted on the base 101 along the third direction. The first protection door 1, the second protection door 2 and the elastic component 4 are mounted inside the face cover 102 and the base 101 to form a protection door module. The face cover 102 is provided with jacks (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 protection door module. The protection door module is detachably mounted inside the socket body. By setting the protection door structure of the socket of this application as an integrated protection door module, the installation and disassembly can be facilitated, and the installation efficiency is greatly improved during the installation process.

[0075] In another possible implementation, the protection door structure of the socket can also be a componentized structure, which is dispersedly installed inside the socket. At this time, the base 101 can serve as a partition between the protection door structure and the socket body, and the face cover 102 is the panel of the socket. During the installation of the socket, the various components of the protection door structure are dispersedly installed on the partition, thereby blocking and protecting the socket sleeves, preventing small objects from contacting the socket sleeves and causing electric shock accidents. That is Figure 1 The base 101 and the face cover 102 in Figure 1 can be understood as the housing of the protection door module, or can be understood as a part of the socket, and both belong to the protection scope of this application.

[0076] Furthermore, as Figure 2a shown, when the protection door structure of the socket of 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 the first direction, and the long side of the second plug hole 103b is in the 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 in cooperation with the DC plugs in the prior art to achieve targeted design. In particular, the protection door component 100 of this embodiment is particularly suitable for DC sockets. For example Figure 2a in Figure 2a , the length of the second plug hole 103b in the second direction is relatively large. If one of the shielding driving surfaces on the rotatably arranged first protection door 1 or the second protection door 2 shields alone, when avoiding, the first protection door 1 or the second protection door 2 needs to rotate a large angle, and a large space is required to avoid the second plug hole 103b, which requires a large space. In this embodiment, however, the third shielding driving surface 13 of the first protection door 1 and the fourth shielding driving surface 23 of the second protection door 2 abut against each other to form the second driving part 32 to shield the second plug hole 103b together. When the plug is inserted, the first protection door 1 and the second protection door 2 rotate in opposite directions to avoid the second plug hole 103b respectively, and only need to rotate half of the angle of the first protection door 1 and the second protection door 2 respectively, which greatly reduces the space occupied by the protection door of the DC socket.

[0077] Of course, the protection door structure of the socket provided in this application can be other targeted designs according to the existing types of plugs. When used in cooperation with AC plugs, the structures of the first plug hole 103a, the second plug hole 103b and their corresponding driving parts 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 the corresponding driving part 3 can also be adjusted accordingly.

[0078] Furthermore, as Figure 2aAs shown, when the protection door component 100 is in the closed state, the closing surfaces of the first protection door 1 and the second protection door 2 in the second direction can respectively cut the first plug hole 103a and the second plug hole 103b into upper and lower symmetric structures. Through this design, the driving parts 3 at both ends of the protection door component 100 can be evenly stressed, improving the sensitivity of the socket protection door component 100.

[0079] Compared with the prior art, the present application provides another idea. By rotatably connecting the first protection door and the second protection door, the protection door mechanism is used to block between the socket and the plug hole in a rotating manner to provide anti-electric shock protection for the socket of the socket, making full use of the space of the product, reducing the volume of the socket, and being more conducive to the miniaturization of the socket product design.

[0080] It should be noted that in the description of the present utility model, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when in use and commonly placed, and is only for the convenience of description, rather than indicating that the device or element referred to must have a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model. In addition, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating relative importance.

[0081] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
