[0002] Currently, power plugs, as a key component connecting electrical equipment to the power supply network, are widely used in various scenarios such as homes, offices, and industries, encompassing various standardized structures such as two-prong and three-prong plugs. With the diversification of consumer electronics, smart home devices, and small appliances, users' needs for plug usage scenarios are becoming increasingly complex. For example, narrow corner sockets, densely packed sockets in multi-outlet power strips, and spaces requiring specific cable routing all place higher demands on the spatial adaptability and flexibility of plugs. However, existing power plugs generally use a fixed connection between the prongs and the plug body. The prongs are often integrated with the plug housing through methods such as injection molding, welding, or bolt fastening. Because the prongs cannot rotate, the plug can only be used under specific angles and spatial conditions. When encountering situations such as limited socket locations, narrow spaces, or special cable routing, users need to frequently adjust the placement of equipment, change socket usage areas, or even be forced to abandon the use of some electrical equipment, significantly reducing ease of use and exhibiting poor adaptability.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0020] This embodiment relates to a rotary plug, see reference... Figures 1-4 The device includes a plug body 100, a pin assembly 200, and a conductive part 300. The pin assembly 200 can rotate 360 ​​degrees relative to the plug body 100 to adjust the pin angle to accommodate various socket specifications, locations, and spatial layouts, thus improving the plug's spatial adaptability. Specifically, in this embodiment, the rotating plug is a US standard plug. In some embodiments, the rotating plug can also be a European standard plug, a Chinese standard plug, or a British standard plug, or other two-prong or three-prong plugs.

[0021] The plug body 100 has an opening 111 at one end, and a connecting wire for connecting to an external electrical device is disposed therein. The connecting wire is used to transmit power from the plug to the external electrical device. The other end of the plug body 100 has a clearance hole (not shown) for the connecting wire to pass through. Specifically, in this embodiment, the plug body 100 includes a first housing 110 and a second housing 120 that are interlocked. The opening 111 is formed on the first housing 110, and a sealing element is provided at the interlocking point between the first housing 110 and the second housing 120. It should be noted that the sealing element can be a sealing ring or a silicone sealing ring, etc., and is not limited thereto. The pin assembly 200 is rotatably mounted on the plug body 100, and one end of it extends from the opening 111 to the outside of the plug body 100 to insert into the socket and conduct electricity from the socket into the plug. The pin assembly 200 can rotate relative to the plug body 100, thereby adjusting the angle and orientation of the pins, significantly improving the spatial adaptability of the plug. The conductive part 300 acts as a bridge between the pin assembly 200 and the connecting wire. One end contacts the pin assembly 200 to achieve dynamic electrical connection with the rotating component, while the other end is electrically connected to the connecting wire to achieve static electrical connection with the fixed component. Thus, during the rotation of the pin assembly 200, the circuit remains continuous, ensuring a stable current transmission from the pin assembly 200 to the connecting wire.

[0022] In this embodiment, refer to Figures 2-4The plug assembly 200 includes a turntable 210, a plug portion 220, and a contact portion 230. The turntable 210 is rotatably mounted on the plug body 100, supporting the plug portion 220 and the contact portion 230. Rotating the plug portion 220 causes the turntable 210 and the contact portion 230 to rotate synchronously with the plug portion 220, achieving stable rotation of the plug assembly 200 relative to the plug body 100 via the turntable 210. The plug portion 220 passes through the turntable 210, with one end extending away from the plug body 100, ensuring stable insertion into the socket hole and forming physical contact. The contact portion 230 is located on the side of the turntable 210 facing the plug body 100, with one end electrically connected to the plug portion 220, receiving the current conducted by the plug portion 220. The other end is in contact with the conductive part 300 to form a dynamic contact, so that when it rotates synchronously with the turntable 210, it always maintains physical contact and electrical conduction with the conductive part 300.

[0023] Furthermore, referring to Figure 3 The plug body 100 has an inwardly recessed groove 112 at the edge of its opening 111, and a protruding boss 211 protruding outward from the edge of its turntable 210. The groove 112 serves as the movement track for the boss 211, providing circumferential space for its circumferential movement. The protruding structure of the boss 211 is embedded within the groove 112, and the turntable 210 and plug body 100 are mechanically coupled, allowing the boss 211 to rotate along the arc-shaped trajectory of the groove 112. This also provides axial and radial limiting for the boss 211, preventing it from detaching from the groove 112. Preferably, the groove 112 may have several limiting grooves, and the surface of the boss 211 may have several limiting protrusions. These protrusions correspond one-to-one with the limiting grooves, ensuring that the boss can stably remain in a preset position after rotation. This prevents the boss 211 from sliding freely due to vibration or slight impact under non-human operation, providing stable support and positioning for the protrusion.

[0024] In this embodiment, refer to Figures 3-4The plug portion 220 includes a neutral wire plug 221, a live wire plug 222, and a grounding plug 223, clearly distinguishing the power supply circuit and the safety circuit of the circuit. This ensures normal power transmission and enhances electrical safety through the grounding plug 223, meeting the basic power supply and safety requirements of electrical equipment. The contact portion 230 includes a first fixing shell 231, a first conductive element 232, a second conductive element 233, and a third conductive element 234. The first fixing shell 231 is used to fix the three conductive elements, ensuring that their positions are relatively fixed during the rotation of the turntable 210, avoiding poor contact due to shaking. It also isolates the three conductive elements to prevent them from coming into contact with each other and causing a short circuit. The first conductive element 232 is located on the side of the first fixing shell 231 facing away from the plug portion 220 and is connected to the neutral wire plug 221 for conduction, receiving the current conducted by the neutral wire plug 221. The second conductive element 233 is arranged around the outside of the first conductive element 232 and is connected to the live wire plug 222 for conduction, receiving the live wire current. The third conductive element 234 is arranged around the outside of the second conductive element 233 and is connected to the grounding pin 223 to conduct electricity, receiving possible leakage current. It should be noted that the first conductive element 232, the second conductive element 233 and the third conductive element 234 can all be conductive coils or concentric ring conductive sheets, and there is no limitation here.

[0025] Furthermore, a conductive connector is provided between the pin portion 220 and the contact portion 230. This conductive connector acts as a conductive bridge between the pin portion 220 and the contact portion 230, achieving both electrical connection and mechanical fixation, ensuring stable current conduction from the pin portion 220 to the contact portion 230. Specifically, three conductive connectors are provided. Each conductive connector can be a conductive post or a conductive sheet, with one end spot-welded to the pin portion 220 or integrally formed, and the other end spot-welded to the corresponding first conductive element 232, second conductive element 233, or third conductive element 234, respectively. It should be noted that the number of conductive connectors can be adjusted according to the number of pins.

[0026] Specifically in this embodiment, refer to Figure 3 To provide precise installation positioning and isolation protection for the three conductive components, the contact portion 230 also includes a first mounting groove 235, a second mounting groove 236, and a third mounting groove 237. The first mounting groove 235 is disposed on the first fixed housing 231 and is used to install the first conductive component 232. The second mounting groove 236 is arranged around the outside of the first mounting groove 235 and is used to install the second conductive component 233. The third mounting groove 237 is arranged around the outside of the second mounting groove 236 and is used to install the third conductive component 234. These three mounting grooves serve as dedicated installation spaces for the three conductive components. Their shape and size are adapted to the conductive components, and the circumferential sidewalls and bottom of the grooves physically constrain the conductive components, preventing radial or axial displacement during the rotation of the turntable 210 or the insertion and removal of the plug.

[0027] In this embodiment, refer to Figures 3-4 The conductive part 300 includes a second fixing shell 310, a first conductive contact 320, a second conductive contact 330, and a third conductive contact 340. The first fixing shell 310 is fixed inside the plug body 100, providing stable mounting support for the three conductive contacts and ensuring that the contact positions do not change with the rotation of the plug assembly 200. One end of the first conductive contact 320 is disposed on the second fixing shell 310, and the other end is in dynamic contact with the first conductive element 232. One end of the second conductive contact 330 is disposed on the second fixing shell 310, and the other end is in dynamic contact with the second conductive element 233. One end of the third conductive contact 340 is disposed on the second fixing shell 310, and the other end is in dynamic contact with the third conductive element 234. The first conductive contact 320, the second conductive contact 330, and the third conductive contact 340 are in dynamic contact with the neutral, live, and ground conductive components of the contact portion 230, respectively. This ensures that when the plug assembly 200 rotates, the conductive contacts always maintain physical contact and electrical continuity with the rotating conductive components. Furthermore, the independent contact structure avoids interference with other polarity contacts, ensuring the independence and safety of the neutral wire path.

[0028] Furthermore, each of the first conductive contact 320, the second conductive contact 330, and the third conductive contact 340 is provided with an elastic element 350. The elastic element 350 is sleeved on the end of the conductive contact away from the contact portion 230, and one end of the elastic element 350 is embedded in the second fixed shell 310, while the other end abuts against the contact head of the conductive contact. It generates continuous pressure through its own elasticity to compensate for minor displacement or wear during the rotation of the contact portion 230, ensuring a tight contact. It should be noted that the elastic element 350 can be a spring or an elastic metal sheet, and the first conductive contact 320, the second conductive contact 330, and the third conductive contact 340 can all be made of copper or silver conductors, without limitation.

[0029] Specifically in this embodiment, both the first fixing shell 231 and the second fixing shell 310 are made of insulating material, which blocks the direct contact of the conductive parts 300 of different polarities, avoids short circuit between live and neutral or between live and ground, and ensures that the three circuits of neutral, live and ground are independently conductive.

[0030] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
