[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application.

[0024] As Figure 1 shown, Figure 1Schematic diagram of the structure of a conversion socket 100 provided by an embodiment of the present application. The conversion socket 100 provided by the embodiment of the present application can be used to insert different types of plugs. Specifically, the conversion socket 100 includes a socket component 1 and a socket body 2.

[0025] In one embodiment, the socket body 2 is provided with national standard pins, a first connection socket, a second connection socket, and a third connection socket. The first connection socket, the second connection socket, and the third connection socket are respectively connected to the national standard pins. The national standard pins are provided on the outer surface of the socket body 2. The first connection socket, the second connection socket, and the third connection socket are located inside the socket body 2. Of course, in other embodiments, the national standard pins can be replaced with German standard pins, European standard pins, etc. The following embodiments will be described by taking the national standard pins as an example.

[0026] Please refer to Figures 1 to 3 , the socket component 1 includes a cover plate 10 and a protection door component 20. The cover plate 10 is buckled with the socket body 2. The cover plate 10 is provided with a first combination jack 101, a second combination jack 102, and a third combination jack 103. Among them, the first combination jack 101 corresponds to the first connection socket. The second combination jack 102 corresponds to the second connection socket. The third combination jack 103 corresponds to the second connection socket. It can be understood that a standard electrical appliance corresponding to the first combination jack 101 can be inserted through the first combination jack 101 and connected to the first connection socket, so as to be conducted with the national standard pins to realize charging. A standard electrical appliance corresponding to the second combination jack 102 can be inserted through the second combination jack 102 and connected to the second connection socket, so as to be conducted with the national standard pins to realize charging. A standard electrical appliance corresponding to the third combination jack 103 can be inserted through the third combination jack 103 and connected to the third connection socket, so as to be conducted with the national standard pins to realize charging.

[0027] Specifically, the cover plate 10 includes a first end face 110 and a second end face 112 which are arranged back to back. The first end face 110 faces the inside of the conversion socket 100, and the second end face 112 faces the outside of the conversion socket 100. In one embodiment, the cover plate 10 is a rectangular plate.

[0028] Optionally, the first combination jack 101 is a British standard jack. The second combination jack 102 is an Australian standard jack. The third combination jack 103 is a US standard jack. The socket component 1 provided by the embodiment of the present application can realize the conversion of socket types, that is, convert the national standard socket into a British standard jack, an Australian standard jack, and a US standard jack for the corresponding plugs to be inserted.

[0029] Please refer to Figure 3 and Figure 4, the first combined socket 101 includes a ground pole hole, a neutral line hole, and a live wire hole. In the following embodiments, the ground pole hole, the neutral line hole, and the live wire hole of the first combined socket 101 are respectively denoted as the first ground pole hole E1, the first neutral line hole N1, and the first live wire hole L1. The second combined socket 102 includes a ground pole hole, a neutral line hole, and a live wire hole, and the second combined socket 102 and the first combined socket 101 share the same first ground pole hole E1. In the following embodiments, the ground pole hole, the neutral line hole, and the live wire hole of the second combined socket 102 are respectively denoted as the first ground pole hole E1, the second neutral line hole N2, and the second live wire hole L2. The third combined socket 103 includes a ground pole hole, a neutral line hole, and a live wire hole. In the following embodiments, the ground pole hole, the neutral line hole, and the live wire hole of the third combined socket 103 are respectively denoted as the second ground pole hole E2, the third neutral line hole N3, and the third live wire hole L3.

[0030] For the convenience of description in the following embodiments, the length direction of the cover plate 10 is defined as the X-axis direction. The width direction of the cover plate 10 is defined as the Y-axis direction. The thickness direction of the cover plate 10 is defined as the Z-axis direction.

[0031] Optionally, as Figure 4 shown, the first neutral line hole N1 and the first live wire hole L1 are arranged along the X-axis direction. The second neutral line hole N2 and the second live wire hole L2 are arranged along the X-axis direction. The first neutral line hole N1 and the second neutral line hole N2 are arranged along the Y-axis direction. The first ground pole hole E1 is located on the side of the second neutral line hole N2 away from the first neutral line hole N1 in the Y-axis direction, or, as Figure 5 shown, the first ground pole hole E1 is located between the second neutral line hole N2 and the first neutral line hole N1 in the Y-axis direction.

[0032] Please refer to Figure 2 and Figure 3 , the protection door assembly 20 is provided on the inner side of the cover plate 10. Specifically, the protection door assembly 20 is provided on the first end face 110 of the cover plate 10. The protection door assembly 20 is used to expose the first combined socket 101 in the first state, expose the second combined socket 102 in the second state, and expose the third combined socket 103 in the third state. It can be understood that in the initial state, the protection door assembly 20 covers at least part of the first combined socket 101, at least part of the second combined socket 102, and at least part of the third combined socket 103. When the British standard plug corresponding to the first combined socket 101 is inserted through the first combined socket 101, the protection door assembly 20 moves and converts from the initial state to the first state for the British standard plug to be inserted. When the Australian standard plug corresponding to the second combined socket 102 is inserted through the second combined socket 102, the protection door assembly 20 moves and converts from the initial state to the second state for the Australian standard plug to be inserted. When the American standard plug corresponding to the third combined socket 103 is inserted through the third combined socket 103, the protection door assembly 20 moves and converts from the initial state to the third state for the American standard plug to be inserted.

[0033] It is understandable. Please refer to Figure 3 and Figure 4 , since the first combined socket 101 and the second combined socket 102 share the same first ground pole hole E1, when a British plug is inserted, the first ground pole hole E1 is occupied, and an Australian plug cannot be inserted through the second combined socket 102; or when an Australian plug is inserted, the first ground pole hole E1 is occupied, and a British plug cannot be inserted through the first combined socket 101. Further, at least a part of the third combined socket 103 is located between the first combined socket 101 and the second combined socket 102. When a plug is inserted into either the first combined socket 101 or the second combined socket 102, a part of the third combined socket 103 is covered by the corresponding plug, and at this time, a US plug cannot be inserted through the third combined socket 103.

[0034] Since sockets with multiple combined sockets often share the neutral wire and the live wire, when multiple electrical appliances are inserted simultaneously, the rated current may be exceeded, posing a safety hazard and not meeting the requirements of relevant standards. Therefore, in this application, by designing the structure of the socket assembly 1, only one type of plug can be inserted each time the socket assembly 1 is used, ensuring that no overload and safety hazards such as fire will occur during the use of the socket assembly 1.

[0035] In addition, by setting the first combined socket 101 and the second combined socket 102 to have the same first ground pole hole E1, and at least a part of the third combined socket 103 is located between the first combined socket 101 and the second combined socket 102, under the condition of meeting relevant standards, the first combined socket 101, the second combined socket 102, and the third combined socket 103 can be concentratedly distributed to reduce the volume of the socket assembly 1.

[0036] By providing the first combined socket 101, the second combined socket 102, and the third combined socket 103 on the cover plate 10 of the socket assembly 1, enabling the first combined socket 101 and the second combined socket 102 to share the same ground pole hole, the number of plugs inserted at one time can be reduced, ensuring that no overload and safety hazards such as fire will occur during use. In addition, the first combined socket 101 and the second combined socket 102 share the same ground pole hole, and the third combined socket 103 is arranged close to the first combined socket 101, which can reduce the overall volume of the socket assembly 1. Further, the protection door assembly 20 exposes the corresponding sockets in the corresponding state to facilitate the insertion of plugs and prevent external metals, dust, etc. from entering the inside of the cover plate 10 through other sockets, which can prevent electric shock and improve safety.

[0037] At least a part of the third combined socket 103 is located between the first combined socket 101 and the second combined socket 102.

[0038] In one embodiment, such as Figure 4As shown, the first ground pole hole E1 is located on the side of the second zero line hole N2 away from the first zero line hole N1 in the Y-axis direction, and the third zero line hole N3 is located on the side of the second zero line hole N2 away from the first zero line hole N1 in the Y-axis direction. It can be understood that the first zero line hole N1, the second zero line hole N2, and the third zero line hole N3 are arranged in sequence in the Y-axis direction. The third live wire hole L3 is located on the side of the second live wire hole L2 away from the first live wire hole L1 in the Y-axis direction; the second ground pole hole E2 is located between the second zero line hole N2 and the second live wire hole L2.

[0039] In another embodiment, as Figure 5 shown, the first ground pole hole E1 is located between the second zero line hole N2 and the first zero line hole N1 in the Y-axis direction, the third zero line hole N3 and the third live wire hole L3 are respectively located on both sides of the first ground pole hole E1 in the X-axis direction, and the second ground pole hole E2 is located between the second zero line hole N2 and the second live wire hole L2.

[0040] By setting the positions of the first ground pole hole E1 and the second ground pole hole E2, the first ground pole hole E1 is located between the zero line hole and the live wire hole of the third combination jack 103, and the second ground pole hole E2 is arranged between the zero line hole and the live wire hole of the second combination jack 102, so as to further make the first combination jack 101, the second combination jack 102, and the third combination jack 103 be concentratedly distributed, thereby reducing the volume of the socket assembly 1 and improving the portability of the socket assembly 1.

[0041] In the following embodiments, the Figure 3 arrangement of the first combination jack 101, the second combination jack 102, and the third combination jack 103 shown is used to illustrate the structure of the protection door assembly 20 provided in the present application.

[0042] As Figure 6As shown, the protection door assembly 20 includes a first protection door 201, a second protection door 202, and a third protection door 203. In the initial state, the first protection door 201, the second protection door 202, and the third protection door 203 respectively cover at least part of the first combined jack 101, the second combined jack 102, and the third combined jack 103. Optionally, in the initial state, the first protection door 201 covers the first neutral line hole N1 and the first live line hole L1 of the first combined jack 101, and the positions of the first protection door 201 corresponding to the second combined jack 102 and the third combined jack 103 are hollowed out. The second protection door 202 covers the second neutral line hole N2 and the second live line hole L2 of the second combined jack 102 in the initial state, and the positions of the second protection door 202 corresponding to the first combined jack 101 and the third combined jack 103 are hollowed out. The third protection door 203 covers the third neutral line hole N3 and the third live line hole L3 of the third combined jack 103 in the initial state, and the positions of the third protection door 203 corresponding to the first combined jack 101 and the second combined jack 102 are hollowed out.

[0043] In one embodiment, as Figure 7 shown, in the initial state, the first protection door 201, the second protection door 202, and the third protection door 203 are arranged in sequence along the Y-axis direction. The second protection door 202 does not cover the second ground pole hole E2. The third protection door 203 does not cover the first ground pole hole E1. When an English plug corresponding to the first protection door 201 is inserted, the first protection door 201 moves along the X-axis direction, exposing the first neutral line hole N1 and the first live line hole L1 of the first combined jack 101. At this time, since the first neutral line hole N1, the first live line hole L1, and the first ground pole hole E1 are all exposed, the English plug can be inserted. When an Australian plug corresponding to the second protection door 202 is inserted, the second protection door 202 moves along the X-axis direction, exposing the second neutral line hole N2 and the second live line hole L2 of the second combined jack 102. At this time, since the second neutral line hole N2, the second live line hole L2, and the first ground pole hole E1 are all exposed, the Australian plug can be inserted. When a US plug corresponding to the third protection door 203 is inserted, the third protection door 203 moves along the X-axis direction, exposing the third neutral line hole N3 and the third live line hole L3 of the third combined jack 103. At this time, since the third neutral line hole N3, the third live line hole L3, and the second ground pole hole E2 are all exposed, the US plug can be inserted. It can be understood that the first protection door 201, the second protection door 202, and the third protection door 203 move respectively due to the external force when the corresponding plugs are inserted. Corresponding through holes are provided on the first protection door 201, the second protection door 202, and the third protection door 203 so that the corresponding jacks covered can be exposed.

[0044] By providing the protection door assembly 20, when the socket is not in use, the protection door assembly 20 is in a tightly closed state to protect the power supply. The three independent protection doors correspond to the three combination sockets, respectively, so that the assembly of the protection door assembly 20 is simple. In addition, the first protection door 201, the second protection door 202 and the third protection door 203 are arranged in sequence along the Y-axis direction and can move independently without affecting each other, thereby improving the reliability and service life of the protection door assembly 20.

[0045] In another embodiment, if Figure 8 As shown, the first protection door 201 is arranged on the inner surface of the cover plate 10, that is, on the first end surface 110, and is slidably connected to the first end surface 110. The second protection door 202 and the third protection door 203 are arranged side by side on the side of the first protection door 201 away from the cover plate 10 and are respectively slidably connected to the first protection door 201. Specifically, the first protection door 201 includes a first surface 210 facing the same direction as the first end surface 110. The second protection door 202 and the third protection door 203 are arranged on the first surface 210. The second protection door 202 and the third protection door 203 are arranged along the Y-axis direction, the second protection door 202 is close to the bottom of the cover plate 10, and the third protection door 203 is close to the top of the cover plate 10. The first protection door 201 and the cover plate 10, the second protection door 202 and the first protection door 201, and the third protection door 203 and the first protection door 201 can all be slidably connected by the cooperation of the slider and the slide groove, the cooperation of the concave part and the convex part, the surface bonding, etc.

[0046] like Figure 9 As shown, when a British standard plug corresponding to the first protective door 201 is inserted, the first protective door 201, the second protective door 202 and the third protective door 203 move to the first position along the Y-axis direction toward the top of the cover plate 10, and the protective door assembly 20 is in the first state. At this time, the first neutral hole N1, the first live hole L1 and the first ground hole E1 are all exposed, and can be inserted into the British standard plug.

[0047] like Figure 10 As shown, when an Australian standard plug corresponding to the second protective door 202 is inserted, the second protective door 202 moves along the X-axis direction toward the right side of the cover 10 to the second position, and the protective door assembly 20 is in the second state. At this time, the first ground hole E1, the second neutral wire hole N2, and the second live wire hole L2 are all exposed for the Australian standard plug to be inserted.

[0048] like Figure 11 As shown, when the US plug corresponding to the third protection door 203 is inserted, the third protection door 203 moves to the third position along the X-axis direction toward the right side of the cover plate 10, and the protection door assembly 20 is in the third state. At this time, the second ground hole E2, the third neutral hole N3 and the third live hole L3 are all exposed for the insertion of the US plug.

[0049] The embodiment of the present application only illustrates the movement direction of the first protective door 201, the second protective door 202 and the third protective door 203 when subjected to external force. It is understandable that in other embodiments, the first protective door 201 can move toward the bottom of the cover plate 10 along the Y-axis direction, and the second protective door 202 and the third protective door 203 can move toward the left side of the cover plate 10 along the X-axis direction. It is understandable that the first protective door 201, the second protective door 202 and the third protective door 203 can be installed independently or integrated into one and installed on the cover plate 10, which can simplify the assembly process and improve production efficiency. In addition, the second protective door 202 and the third protective door 203 are arranged on the side of the first protective door 201 away from the cover plate 10, and move on the first protective door 201, which can reduce the volume of the socket assembly 1 so as to produce a miniaturized socket assembly 1.

[0050] For further information, please refer to Figure 6 and Figure 12 , a first limiting protrusion 211 and a second limiting protrusion 212 are provided on the side of the first protection door 201 facing away from the cover plate 10. A first limiting surface 211a is provided on the side of the first limiting protrusion 211 facing the first surface 210 of the first protection door 201, and a second limiting surface 212a is provided on the side of the second limiting protrusion 212 facing the first surface 210 of the first protection door 201. The second protection door 202 is partially sandwiched between the first limiting surface 211a and the first surface 210, and the third protection door 203 is partially sandwiched between the second limiting surface 212a and the first surface 210. When the second protection door 202 moves along the X-axis direction under the action of an external force, the second protection door 202 partially abuts between the first limiting surface 211a and the first surface 210 to prevent the second protection door 202 from slipping along the Z-axis direction. When the third protection door 203 moves along the X-axis direction under the action of external force, the third protection door 203 partially abuts between the second limiting surface 212a and the first surface 210 to prevent the third protection door 203 from slipping along the Z-axis direction.

[0051] In this embodiment, by providing a first limiting protrusion 211 and a second limiting protrusion 212 on the first protective door 201, the second protective door 202 and the third protective door 203 can move better along the X-axis direction on the first protective door 201, and can prevent the second protective door 202 and the third protective door 203 from being separated and loosened from the first protective door 201 respectively under the action of external force, thereby reducing the gap between the protective door assembly 20 and the cover plate 10 and improving the protective performance of the protective door assembly 20.

[0052] Further, such as Figure 13As shown in the figure, the first protection door 201 includes a first inclined surface 213 and a second inclined surface 214. When the first protection door 201 is in the initial state, the first inclined surface 213 and the second inclined surface 214 are respectively arranged opposite to the first live wire hole L1 and the first neutral wire hole N1 of the first combined socket 101. In other words, when the first protection door 201 is in the initial state, the first inclined surface 213 covers at least part of the first live wire hole L1. The second inclined surface 214 covers at least part of the first neutral wire hole N1. The second protection door 202 includes a third inclined surface 220 and a fourth inclined surface 221. When the second protection door 202 is in the initial state, the third inclined surface 220 and the fourth inclined surface 221 are respectively arranged opposite to the second live wire hole L2 and the second neutral wire hole N2 of the second combined socket 102. In other words, when the second protection door 202 is in the initial state, the third inclined surface 220 covers at least part of the second live wire hole L2. The fourth inclined surface 221 covers at least part of the second neutral wire hole N2. The third protection door 203 includes a fifth inclined surface 230 and a sixth inclined surface 231. When the third protection door 203 is in the initial state, the fifth inclined surface 230 and the sixth inclined surface 231 are respectively arranged opposite to the third live wire hole L3 and the third neutral wire hole N3 of the third combined socket 103. In other words, when the third protection door 203 is in the initial state, the fifth inclined surface 230 covers at least part of the third live wire hole L3. The sixth inclined surface 231 covers at least part of the third neutral wire hole N3.

[0053] By providing two inclined surfaces on the first protection door 201 to cover the first live wire hole L1 and the first neutral wire hole N1, two inclined surfaces on the second protection door 202 to cover the second live wire hole L2 and the second neutral wire hole N2, and two inclined surfaces on the third protection door 203 to cover the third live wire hole L3 and the third neutral wire hole N3, while playing a protective role, the inclined surfaces can reduce the force required to insert the plug and improve the efficiency of plug insertion.

[0054] Furthermore, as Figure 12As shown in the figure, the socket assembly 1 further includes at least one first elastic member 301, at least one second elastic member 302, and at least one third elastic member 303. At least one first protrusion 104 is provided on the inner surface of the cover plate 10. The first elastic member 301 is elastically connected between one end of the first protection door 201 and the first protrusion 104. The first elastic member 301 has a buffering effect when the British standard plug is inserted and the first protection door 201 moves towards the top of the cover plate 10 to the first position, and has the effect of driving the first protection door 201 to move during the process of pulling out the British standard plug and the first protection door 201 returning from the first position to the initial state. At least one second protrusion 105 and at least one third protrusion 106 are provided on the side of the first protection door 201 facing away from the cover plate 10. The second protrusion 105 and the third protrusion 106 are spaced apart. The second elastic member 302 is elastically connected between one end of the second protection door 202 and the second protrusion 105. The third elastic member 303 is elastically connected between one end of the third protection door 203 and the third protrusion 106. The second elastic member 302 has a buffering effect when the Australian standard plug is inserted and the second protection door 202 moves towards the right side of the cover plate 10 to the second position, and has the effect of driving the second protection door 202 to move during the process of pulling out the British standard plug and the second protection door 202 returning from the second position to the initial state. The third elastic member 303 has a buffering effect when the US standard plug is inserted and the third protection door 203 moves towards the right side of the cover plate 10 to the third position, and has the effect of driving the second protection door 202 to move during the process of pulling out the US standard plug and the third protection door 203 returning from the third position to the initial state.

[0055] The above are some embodiments of the present application. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present application.
