[0020] As in the Fig. As shown, the present utility model provides an adapter socket, the adapter socket comprising a socket body 1 and a swivel joint 2. A charging interface 31 is provided on the socket body 1, the charging interface 31 being a low-voltage output interface with a specific voltage of 5V to 20V, for supplying power and charging various electronic devices. The swivel joint 2 is rotatably mounted on the socket body 1, with a plug-in receiving opening 2211 being provided at one end of the swivel joint 2, which is exposed on the first surface of the socket body 1, and plug-in pins 2122 being provided at the other end of the swivel joint 2, which protrude from the second surface of the socket body 1 and serve for insertion into fixed sockets. The swivel joint 2 is electrically connected to the charging interface 31 to enable power transmission.Regarding the first surface and the second surface, it can be understood that these are the front and back of the socket body 1, with the charging interface 31 being exposed on the front of the socket body 1.

[0021] The swivel connection head 2 is rotatably mounted on the socket body 1, allowing the socket body 1 to rotate freely through 360 degrees when the plug pins 2122 are inserted into an external wall socket. The charging interface 31 includes various specifications such as USB-A, Type-C, etc., to meet the charging needs of different devices. During use, after the adapter socket has been plugged into a wall socket, the user can manually rotate the socket body 1 to adjust its orientation according to the actual room layout.

[0022] For the rotary mounting between the rotary connection head 2 and the socket body 1, in some embodiments a direct connection between the rotary connection head 2 and the socket body 1 can be made, or a bearing structure can be arranged between the rotary connection head 2 and the socket body 1 to achieve the rotary mounting. In some embodiments of the rotary connection head 2, as in the Fig. As shown, the rotary connection head 2 comprises a plug component 21, a socket component 22, and a power supply component 23. The plug component 21 has plug pins 2122 for connection to mains sockets. The socket component 22 is fixedly connected to the plug component 21, with the socket component 2211 having a plug-receiving opening 2211 at the end of the socket component 22 facing away from the plug component 21, for receiving plugs of other electrical devices. The power supply component 23 is arranged in the socket body 1, forming a rotating electrical connection with the plug component 21 and simultaneously being electrically connected to the charging interface 31.

[0023] The plug component 21 and the socket component 22 form a complete structure through the connection of connecting columns and sockets, but can also form a complete structure through screw connections or snap-fit ​​connections. The power supply component 23 has an annular structure or a circular opening, with the power supply component 23 arranged around the plug component 21 and electrically connected to the plug component 21 to maintain a stable electrical connection during rotation. The plug component 21 serves for current collection and mechanical support, while the socket component 22 provides standardized plug interfaces. When the socket body 1 or the rotary connection head 2 rotates, the plug component 21 and the socket component 22 rotate as a whole relative to the socket body 1, while the power supply component 23 remains fixed relative to the socket body 1.The power transmission path runs from the plug component 21 via the power supply component 23 to the charging interface 31, whereby the connection remains stable throughout the entire process in the rotational state and there are no power interruptions or poor contact.

[0024] With regard to the rotary connection between the rotary connection head 2 and the socket body 1, specifically at least one of the plug component 21 and socket component 22 forms a rotary mounting relationship with the socket body 1.

[0025] Regarding the socket body 1, this comprises a front housing and a rear housing, wherein the plug component 21 is rotatably mounted to the rear housing and the socket component 22 is rotatably mounted to the front housing. The first surface, or front, is located on the front housing, and the second surface, or rear, is located on the rear housing.

[0026] In some embodiments of the rotary connection between plug component 21 and socket body 1, as in the Fig. As shown, the plug component 21 comprises a first turned part 211, wherein a first rotary mounting structure 2112 is provided on the outer circumferential surface of the first end of the first turned part 211 to achieve a rotary coupling with the socket body 1. The first end of the first turned part 211 is connected to the socket component 22, and the second end of the first turned part 211 projects from the second surface of the socket body 1.

[0027] The first rotary mounting structure 2112 can be a rotary ring, a rotary groove, etc., provided on the outer circumferential surface of the first end of the first rotary part 211, wherein the first rotary part 211 is rotatably mounted to the socket body 1 by means of the rotary ring or rotary groove. The first rotary mounting structure 2112 can also be a bearing coupling structure, a sleeve coupling structure, or another low-friction rotary structure. The first rotary part 211 serves as a central support structure and must ensure both smooth rotation and provide the bridging function for the electrical connection.

[0028] In some specific embodiments of the first turned part 211, as in the Fig. As shown, an assembly chamber 2111 is provided inside the first turned part 211, with an opening connected to the assembly chamber 2111 being provided at one end of the first turned part 211. The connector component 21 further comprises a pin insertion mechanism 212 and a guide mechanism 213. The pin insertion mechanism 212 comprises a first holder 2121 and insertion pins 2122 arranged on the first holder 2121, wherein the first holder 2121 is arranged in the assembly chamber 2111 and the insertion pins 2122 project from the second end of the first turned part 211. The guide mechanism 213 comprises a second bracket 2131 and two guide plates 2132, wherein the second bracket 2131 is arranged at the opening of the assembly chamber 2111, one end of the two guide plates 2132 is arranged on the second bracket 2131, the other end of the two guide plates 2132 projects into the assembly chamber 2111 and is each connected to the two plug pins 2122.The two circuit boards 2132 are electrically connected to the power supply component 23; at the bottom of the plug-in opening 2211, two first through holes 2213 are provided into which external plugs can be inserted, the two first through holes 2213 each penetrating to the two circuit boards 2132, so that external plugs can be inserted directly into the two circuit boards 2132.

[0029] The first holder 2121 is made of insulating material to ensure electrical insulation between the plug pins 2122. The second holder 2131 is also made of insulating material, and its structural design must ensure both the reliable attachment of the circuit boards 2132 and the coupling with the power supply component 23. The circuit boards 2132 are made of elastic conductive materials such as phosphor bronze or beryllium copper to ensure both conductivity and a degree of elasticity. During assembly, the plug-in mechanism 212 is first inserted into the mounting chamber 2111 of the first turned part 211, and then the guide mechanism 213 is mounted in the open position to ensure a reliable connection between the circuit boards 2132 and the plug pins 2122.This layered structural design facilitates assembly and maintenance while ensuring the reliability of the electrical connection.

[0030] Furthermore, as in the Fig. As shown, the guide mechanism 213 additionally comprises two metal spring plates 2133, each arranged on the second support 2131. One end of each of the two metal spring plates 2133 is connected to the two guide plates 2132, while the other end of each metal spring plate 2133 extends outwards to the outer surface of the second support 2131, with the other end of each metal spring plate 2133 resting elastically against the current supply component 23. The current supply component 23 is arranged around the second support 2131.

[0031] The metal spring plates 2133 are made of stainless steel or spring copper and heat-treated to ensure good elasticity and conductivity. The curved shape of the spring plates is optimally designed to provide stable contact pressure when in contact with the power supply component 23. As the rotary joint head 2 rotates, the metal spring plates 2133 slide on the inner surface of the power supply component 23, maintaining a consistently good electrical contact. The connection between the metal spring plates 2133 and the circuit boards 2132 is achieved by riveting or welding to ensure a secure connection. The circumferential design of the power supply component 23 ensures that a contact point connection is maintained regardless of the angle of rotation, significantly increasing reliability.

[0032] To fix the position of the metal spring plates 2133, clamping grooves are provided on both sides of the second holder 2131 in this embodiment. The central parts of the two metal spring plates 2133 are each arranged in the two clamping grooves. The shape of the clamping grooves corresponds to the metal spring plates 2133, whereby the position of the spring plates can be fixed and their elastic deformation is not impaired.

[0033] During the assembly of the metal spring plates 2133, their central sections are pressed into the clamping grooves to prevent the spring plates from slipping during operation. This ensures the precise positioning of the spring plates while simultaneously allowing the necessary elasticity at their ends.

[0034] In some embodiments of the power supply component 23, as in Fig. As shown, the power supply component 23 comprises a third holder 231 and two metal rings 232. The third holder 231 is arranged in the socket body 1, and the two metal rings 232 are arranged on the third holder 231, with the two metal rings 232 being arranged around the plug component 21 and electrically connected to the plug component 21. Specifically, the two metal rings 232 each bear against the two metal spring plates 2133.

[0035] The third bracket 231 is made of insulating material and provides support and positioning for the metal rings 232. The two metal rings 232 correspond to the neutral and phase conductors, respectively, and are made of brass or phosphor copper. Their surfaces are silver-plated or gold-plated to reduce contact resistance. The inner diameter of the metal rings 232 corresponds to the outer diameter of the second bracket 2131 to ensure good sliding contact with the metal spring plates 2133. During assembly, the metal rings 232 are first mounted on the third bracket 231, and then the third bracket 231 is secured in the socket body 1. When the plug component 21 rotates, the metal spring plates 2133 slide on the inner surface of the metal rings 232, thus enabling continuous current transmission.This ring-shaped contact design ensures that the electrical connection is maintained at every angle of rotation, significantly increasing the reliability of the product.

[0036] As in Fig. As shown, the third bracket 231 comprises a mounting plate 2311 and a sleeve 2312. The mounting plate 2311 is fixed inside the socket body 1, and the sleeve 2312 extends from the mounting plate 2311 and is arranged around the plug component 21. Annular grooves are provided on the inner circumferential surfaces of both ends of the sleeve 2312, with the two metal rings 232 each positioned in the two annular grooves. The mounting plate 2311 is fastened in the socket body 1 by screws or snap-fit ​​connections to ensure the precise position of the third bracket 231. The sleeve 2312 is manufactured by injection molding in one piece, with the dimensions of the annular grooves precisely matching the metal rings 232 to ensure both the accurate positioning of the metal rings 232 and to prevent their rotation or displacement.The metal rings 232 are assembled using an interference fit. The depth of the ring grooves ensures that the surface of the metal rings 232 protrudes slightly beyond the inner surface of the sleeve 2312 to form good contact with the metal spring plates 2133. This structural design not only provides stable mechanical support but also ensures reliable electrical insulation. The length of the sleeve 2312 is optimized to provide sufficient guidance and support for the metal spring plates 2133 and to prevent wobbling during rotation.

[0037] In some embodiments of the socket component 22, as in the Fig. As shown, the socket component 22 comprises a second rotating part 221, wherein the plug receiving opening 2211 is provided at the first end of the second rotating part 221, and furthermore a second rotating mounting structure 2212 for rotatable mounting with the socket body 1 is provided at the first end of the second rotating part 221. The second end of the second rotating part 221 is connected to the plug component 21, and two first through-holes 2213 are provided at the bottom of the plug receiving opening 2211, into which external plugs can be inserted, the two first through-holes 2213 extending to the plug component 21.

[0038] The second turned part 221 is made of high-strength engineering plastic, with the plug-in receiving opening 2211 conforming to German or French standard dimensions. The second rotary mounting structure 2212 can be a rotary ring, a rotary groove, etc., provided on the outer circumferential surface of the first end of the second turned part 221, wherein the second turned part 221 is rotatably mounted to the socket body 1 by means of the rotary ring or rotary groove. The second rotary mounting structure 2212 can also be a bearing coupling structure, a sleeve coupling structure, or another low-friction rotary structure.

[0039] The connection between the second rotating part 221 and the plug component 21 is made by a screw connection or a snap-fit ​​connection to ensure a secure connection. In use, the user can insert a standard mains plug into the plug receptacle 2211 and adjust the angle of the socket body 1 by rotating it to find the most suitable position. This design retains the functionality of conventional sockets while adding the flexibility of directional adjustment.

[0040] To improve the stability of the connection of external plugs, in this embodiment, as in the Fig. As shown, a clamping spring plate 222 has been added to the socket component 22. A through-groove 2214 is provided on the side wall of the second rotating part 221. The clamping spring plate 222 is arranged at the second end of the second rotating part 221, the end of the clamping spring plate 222 being a clamping element that extends to the through-groove 2214 and projects into the plug-receiving opening 2211 to clamp external plugs.

[0041] The clamping spring plate 222 is made of spring steel and heat-treated for permanent elasticity. The shape of the clamping element is optimized to form a surface contact with the connector pins and provide a uniform clamping force. The dimensions of the through-groove 2214 are precisely controlled to allow free movement of the clamping element while preventing excessive gaps from detracting from the appearance. When an external connector is inserted, it presses the clamping element open, with the elastic deformation of the spring plate generating a continuous clamping force to prevent accidental disconnection. This design is particularly suitable for mobile or vibration-prone environments and ensures a reliable power connection. Simultaneously, the appropriate clamping force ensures smooth insertion and removal.

[0042] To precisely position the clamping spring plate 222, a limiting groove and a positioning pin are provided at the second end of the second rotating part 221 in this embodiment. The positioning pin is arranged in the limiting groove. A positioning hole is provided in the central part of the clamping spring plate 222, with the central part of the clamping spring plate 222 being inserted through the positioning hole onto the positioning pin and located in the limiting groove.

[0043] The depth of the limiting groove corresponds to the thickness of the clamping spring plate 222 to ensure a flat surface after the spring plate is installed. The positioning pin has a cylindrical design and forms a push-fit connection with the positioning hole. The positioning pin and the limiting groove work together to prevent excessive displacement of the spring plate during operation, ensuring the precise position of the clamping spring plate 222 while simultaneously allowing its necessary elastic deformation.

[0044] To ensure safety during use and to prevent the ingress of foreign objects into the plug-in receiving opening 2211, in this embodiment, as in the Fig. As shown, an elastic locking mechanism 223 has been added. The elastic locking mechanism 223 comprises a guide groove body 2231, a sliding element 2232, and a spring 2233. A sliding groove 22311 is provided on the guide groove body 2231, wherein two second through-holes 22312 are provided in the sliding groove 22311, each corresponding to the two first through-holes 2213. The sliding element 2232 is arranged to slide in the sliding groove 22311 and passes through a closed position and an open position, wherein closing parts 22321 are provided at both ends of the sliding element 2232 for closing the second through holes 22312, and sliding ramps 22322 are provided on the surface of the closing parts 22321 for moving the sliding element 2232, wherein the sliding ramps 22322 are located on the side of the closing parts 22321 facing the first through holes 2213.When the sliding element 2232 is in the closed position, the locking parts 22321 close the corresponding secondary through-holes 22312; when the sliding element 2232 is in the open position, the locking parts 22321 release the corresponding secondary through-holes 22312. The spring 2233 is arranged in the sliding groove 22311, with the spring 2233 bearing against the sliding element 2232 and pushing the sliding element 2232 towards the closed position.

[0045] The guide groove body 2231 is attached to the outer base of the plug receptacle opening 2211, with the direction of the sliding groove 22311 corresponding to the connecting line of the two plug pins 2122. The sliding element 2232 is made of engineering plastic, with the shape of the closing parts 22321 corresponding to the second through-holes 22312. The angle of the sliding ramps 22322 is optimized to ensure that the plug pins can slide the sliding element 2232 smoothly. The spring force of the spring 2233 is precisely calculated to allow the sliding element 2232 to slide on during normal insertion and removal, and also to close the through-holes promptly after the plug is withdrawn. When no plug is inserted, the spring 2233 pushes the sliding element 2232 into the closed position, with the locking parts 22321 blocking the second through holes 22312 and preventing the ingress of dust or foreign objects.When a plug is inserted, the plug pins contact the sliding ramps 22322 and, under compression from the spring 2233, push the sliding element 2232, opening the second through-holes 22312 and allowing the plug pins to penetrate. This automatic locking mechanism significantly increases the product's safety performance.

[0046] In some further embodiments of the elastic locking mechanism 223, as in Fig. As shown, a receiving groove 22323 extending along the longitudinal direction of the sliding element 2232 is provided, the receiving groove 22323 extending into the sliding groove 22311. A stop block 22313 extending towards the receiving groove 22323 is provided in the sliding groove 22311, the stop block 22313 being located between the two second through holes 22312. The spring 2233 is arranged in the receiving groove 22323, with one end of the spring 2233 bearing against the inner wall of the receiving groove 22323 and the other end of the spring 2233 bearing against the stop block 22313.

[0047] The dimensions of the receiving groove 22323 correspond to the outer diameter of the spring 2233 and provide stable guidance for the spring 2233. The stop block 22313 serves as a fixed support point for the spring 2233, its position ensuring that the spring 2233 remains stable during the compression and expansion process. This design fully encloses the spring 2233 within the mechanism, preventing damage from exposure. As the sliding element 2232 moves, the spring 2233 compresses or expands within the receiving groove 22323, with the stop block 22313 preventing displacement of the spring 2233. The entire mechanism is compact, space-saving, and highly reliable. The preload of the spring 2233 can be adjusted by the position of the stop block 22313 to ensure adequate closing force.

[0048] Furthermore, as in Fig.As shown, the adapter socket further comprises a charging mainboard 3, wherein the charging mainboard 3 is arranged in the socket body 1 and the charging mainboard 3 has the charging interface 31. A transformer circuit and a charging circuit are provided on the charging mainboard 3, wherein the charging interface 31 includes at least one USB interface, one Type-C interface, and one Lightning interface. The charging mainboard 3 is made of FR-4 material, and the circuit design complies with safety regulations.

The charging circuit includes an intelligent detection chip that can automatically detect the type of connected device and provide the appropriate charging voltage and current.The layout of the charging interface 31 is optimized to prevent mutual interference when multiple interfaces are used simultaneously. The charging mainboard 3 also integrates several safety mechanisms, such as overvoltage protection, overcurrent protection, and short-circuit protection, to ensure safe use. This integrated design allows the adapter socket to provide both conventional AC power output and convenient charging solutions for modern electronic devices.
