[0002] Existing sockets are usually designed based on plug standards of specific countries or regions, such as American Standard, European Standard, British Standard, Australian Standard, etc. Most electrical sockets on the market are standard sockets, which are only suitable for standard single-shaped plugs.
[0003] Hotels with foreign-related qualifications often receive a large number of foreign tourists. The electrical outlets in these hotels are not compatible with electronic devices from different countries and regions, making it impossible for tourists to charge or perform other operations on their electronic devices. Utility Model Content
[0004] To accommodate standard plugs from around the world, this application provides a universal socket.
[0005] The universal socket provided in this application adopts the following technical solution:
[0006] A universal socket includes a panel, a mounting base, and a socket assembly disposed inside the mounting base. The panel has a through hole for inserting a power supply contact piece. The socket assembly includes a grounding socket and a wiring socket. The wiring socket is divided into a live wire socket and a neutral wire socket. The live wire socket and the neutral wire socket have the same structure.
[0007] The grounding socket includes a fixing piece, a first clamping piece fixedly connected to both sides of the fixing piece, and a second clamping piece located on one side of the first clamping piece and fixedly connected to both sides of the fixing piece;
[0008] The wiring socket includes a connecting piece, a third clamping piece fixedly connected to both ends of the connecting piece, and an auxiliary clamping piece disposed between the two third clamping pieces.
[0009] By adopting the above technical solution, the socket can clamp electrical contact pieces of different shapes, thereby adapting to plugs of different standards. This solves the compatibility problem encountered when using electrical appliances across borders, allowing electrical products from different countries to be used directly on the socket without the need to design different socket versions for each region.
[0010] Optionally, the first clamping piece protrudes outward to form an arc portion, a first insertion cavity is formed between the two arc portions, a second insertion cavity is formed between the two second clamping pieces, and a third insertion cavity is formed on the side of the two first clamping pieces near the second clamping piece.
[0011] By adopting the above technical solution, the first clamping piece can provide stable clamping for the cylindrical electrical contact piece, ensuring that it can be fixed after being inserted into the first cavity. The second cavity formed by the second clamping piece can stably clamp the square electrical contact piece. The third cavity is used to clamp the sheet-shaped electrical contact piece. Therefore, the grounding socket can be adapted to cylindrical electrical contact pieces, sheet-shaped electrical contact pieces, and square electrical contact pieces, so that the grounding socket can tightly clamp and fix the cylindrical electrical contact piece, while also accommodating and firmly clamping the flat electrical contact piece, thereby achieving compatibility with different plugs and improving flexibility and practicality.

At the same time, the guide plate can reduce the resistance when plugging and unplugging the plug, improving the user experience.
[0014] Optionally, the auxiliary clamping piece bends toward the third clamping piece and forms an oblique groove with the third clamping piece.
[0015] By adopting the above technical solution, when the plug is inserted, the auxiliary clamping piece can abut against the angled electrical contact piece, which enhances the stability of the plug insertion, reduces the contact problems caused by the angled electrical contact piece insertion, and improves the safety of the insertion and removal process, ensuring the reliability of power transmission.
[0016] Optionally, the inner wall of the third clamping piece is provided with a positioning groove.
[0017] By adopting the above technical solution, plugs of European and French standards can insert their cylindrical contact pieces into the groove, effectively increasing the tightness of the connection between the clamping piece and the cylindrical contact piece, reducing poor contact or loosening caused by the movement of the cylindrical contact piece, thereby improving the safety and stability of the socket.
[0018] Optionally, the through hole includes a grounding hole and a wiring hole, and the through hole fits against the outer edge of the socket assembly and can match plugs of various different standards.
[0019] By adopting the above technical solution, it is possible to adapt to various types of plugs, realize universal connection between plugs and sockets, facilitate users to plug and unplug plugs of different standards, and improve the flexibility of socket use.
[0020] Optionally, a circuit board is provided inside the mounting base, the circuit board being used for intelligent control of the socket.
[0021] By adopting the above technical solutions, intelligent control of sockets can be achieved. Users can remotely control socket switches, timer switches, and monitor socket current and voltage, effectively improving the convenience, safety, and energy efficiency of sockets.
[0022] Optionally, the fixing piece is fixedly connected to a first pin on the side opposite to the first clamping piece, and the connecting piece is fixedly connected to a second pin on the side opposite to the second clamping piece. The first pin and the second pin pass through the circuit board and are soldered to the circuit board.
[0023] By adopting the above technical solution, the socket assembly can be fixed on the circuit board, and the power supply of the socket can be controlled by the circuit board, thereby improving the convenience and safety of use.

Detailed Implementation
[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0036] This application discloses a universal socket. (Refer to...) Figure 1 , Figure 2 The universal socket includes a plastic panel 1, a mounting base 2, and a socket assembly 3 disposed within the mounting base 2. The mounting base 2 is used to fix the socket to the wall and connect it to the power cord, enabling the socket to conduct electricity. The socket assembly 3 is used to form a stable electrical connection with the electrical contacts of the plug to transmit current. The plastic panel 1 is used to isolate the internal metal parts of the socket, preventing users from directly contacting the internal metal parts of the socket and reducing the risk of electric shock. The plastic panel 1 has a through hole 11 for the electrical contacts of the plug to be inserted into the socket. When using the socket, the user only needs to align the plug with the through hole 11 and insert the plug to obtain power.
[0037] Reference Figure 3 , Figure 4 The socket assembly 3 includes a grounding socket 31 and a wiring socket 32. The wiring socket 32 includes a neutral wire socket 3202 and a live wire socket 3201, both of which have the same structure. The grounding socket 31 includes a fixing piece 311, a first clamping piece 312 fixedly connected to both sides of the fixing piece 311, and a second clamping piece 313 located on one side of the first clamping piece 312 and fixedly connected to both sides of the fixing piece 311. The first clamping piece 312 protrudes outward to form an arc portion, and a first insertion cavity 314 is formed between the two arc portions, which can provide stable clamping for the cylindrical point contact piece, ensuring that it can be fixed and no longer slide after insertion. A second insertion cavity 315 is formed between the two second clamping pieces 313, which can stably clamp a square electrical contact piece. A third insertion cavity 316 is formed on the side of the two first clamping pieces 312 near the second clamping pieces 313, which can stably clamp a sheet-shaped electrical contact piece. This structure allows the grounding socket 31 to accommodate electrical contact pieces of different sizes and shapes and to provide stable clamping and fixation for them, thereby achieving compatibility with different plugs and improving the flexibility and practicality of use.
[0038] Reference Figure 5 The connector 32 includes a connecting piece 321, third clamping pieces 322 fixedly connected to both ends of the connecting piece 321, and an auxiliary clamping piece 323 disposed between the two third clamping pieces 322. The inner wall of the third clamping piece 322 is provided with an arc-shaped positioning groove 325, which allows European standard, French standard and other plugs to insert their cylindrical contact pieces into the positioning groove 325, effectively increasing the tightness of the connection between the clamping piece and the cylindrical contact piece, reducing poor contact or loosening caused by the movement of the cylindrical contact piece, and can also be adapted to contact pieces of other shapes, thereby improving the safety and stability of the socket.
[0039] Reference Figure 5 The auxiliary clamping piece 323 bends toward the third clamping piece 322 and forms an oblique slot 324 with the third clamping piece 322. When the plug is inserted, the auxiliary clamping piece 323 can abut against the electrical contact piece, reducing the problem of poor contact caused by the oblique electrical contact piece being inserted, while improving the safety of the insertion and removal process and ensuring the reliability of power transmission.
[0040] Reference Figure 6 , Figure 7 The through hole 11 includes a grounding hole 111 and a wiring hole 112. The through hole 11 fits the outer edge of the socket assembly 3 to match various standard plugs, realizing a universal connection between the plug and the socket, making it convenient for users to plug and unplug plugs of different standards, and improving the flexibility of the socket.
[0041] Reference Figure 6 , Figure 7 Based on the shape and position of the plugs inserted into each position of the through hole 11, the through hole 11 is divided into different areas. The grounding hole 111 is divided into three areas: A, B, and C. Area A is suitable for cylindrical grounding plugs such as those of South African and Indian standards, as well as square grounding plugs such as those of British standards. Area B is suitable for flat grounding plugs such as those of Chinese and Austrian standards. Area C is suitable for cylindrical grounding plugs such as those of French and Israeli standards, as well as irregularly shaped grounding plugs such as those of Japanese and American standards.
[0042] Reference Figure 6 , Figure 7 The wiring hole 112 is divided into four areas: D, E, F, and G. Area D is suitable for vertically oriented flat plugs, such as Japanese and American standard plugs; area E is suitable for British standard rectangular plugs; area F is suitable for Danish, French, and European standard cylindrical plugs; and area G is suitable for Chinese standard, Argentine standard, and Austrian standard flat plugs.
[0043] Reference Figure 2 The mounting base 2 contains a circuit board 4, which is used for intelligent control of the socket. Users can remotely control the socket switch, monitor the current and voltage of the socket, and other functions, effectively improving the convenience, safety and energy efficiency of use.
[0044] Reference Figure 4 , Figure 5 The fixing piece 311 is fixedly connected to the first pin 317 on the side opposite to the first clamping piece 312, and the connecting piece 321 is fixedly connected to the second pin 326 on the side opposite to the second clamping piece 313. The first pin 317 and the second pin 326 pass through the circuit board 4 and are soldered to the circuit board 4, so that the socket assembly 3 can be stably connected to the circuit board 4, and the power supply of the socket can be controlled by the circuit board 4, thereby improving the safety and convenience of use.
[0045] Reference Figure 3 The clamping plates in the socket assembly 3 are all provided with guide plates 33. The guide plates 33 are bent away from the side of the socket to form an inverted V-shaped guide surface. When the plug is inserted, the guide plates 33 can effectively guide the plug into the socket, effectively avoiding jamming and damage to the clamping plates due to improper plug alignment. At the same time, the guide plates 33 can reduce the resistance when plugging and unplugging the plug, improving the user experience.
[0046] The implementation principle of a universal socket in this application embodiment is as follows:
[0047] When used with a national standard plug, the plug is connected to area B and area G and inserted into the third socket 316. The first clamping piece 312 can stably clamp the flat plug, and the auxiliary clamping piece 323 and the third clamping piece 322 can resist the obliquely set flat plug to ensure a stable connection.
[0048] When applied to British standard plugs, the plug is connected to areas A and E and inserted into the first socket 314. The first clamping piece 312 stably clamps the block plug, and the third clamping piece 322 and the auxiliary clamping piece 323 in the wiring hole 112 can stably clamp the block plug, so that the British standard plug can be stably connected.
[0049] When used with Japanese standard, American standard and other plugs, the plug is connected to the C and D areas and inserted into the second socket 315. The second clamping piece 313 can clamp the irregular plug. The auxiliary clamping piece 323 and the third clamping piece 322 in the wiring hole 112 can stably connect the vertically set plate plug and ensure the stability of the connection.
[0050] When used with European, Indian, French and other standard plugs, the plug is connected to area A and area F and inserted into the first socket 314. The arc part of the first clamping piece 312 can stably clamp the cylindrical plug. The third clamping piece 322 in the wiring hole 112 is provided with a positioning groove 325, so that the cylindrical plug can be stably clamped by the third clamping piece 322, so that the connection is stable.
[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
