Description

Technical Field

[0001] This utility model relates to the field of electronic device charging, and in particular to a cube socket with wireless charging function. Background Technology

[0002] With the widespread use of electronic devices, integrated charging equipment is gradually becoming a market trend. In existing technologies, such as the "wireless charging cube" disclosed in patent CN210350864U, although it integrates sockets, wireless charging and wired charging functions through a cubic shell and achieves multi-functionality to a certain extent, its installation design of wireless charging module and safety door structure still has significant defects.

[0003] Regarding the wireless charging module, this patent embeds the wireless PCB board into the charging board mounting slot on the back of the wireless charging surface, requiring additional components such as anti-slip pads, insulating sheets, and support pieces for fixation. This design results in a complex installation structure. The wireless PCB board needs to be precisely embedded into the recessed charging board mounting slot and stacked layer by layer with components such as anti-slip pads and insulating sheets, making the assembly process cumbersome and requiring high production precision. Furthermore, component assembly is challenging, as the wireless charging surface, socket surface, and wired charging surface are distributed on different end faces. Multiple modules, including a power conversion board and socket assembly, need to be internally located. Each component requires additional isolation and fixation through insulating sheets, wire clamps, and other structures, further increasing assembly complexity.

[0004] Regarding the safety door structure, existing technologies generally employ independent safety door component designs, requiring each power supply unit to have its own safety door mechanism, resulting in internal structural redundancy. Furthermore, traditional safety door components typically use a linear sliding structure, which carries the risk of jamming and requires significant installation space, hindering product miniaturization design.

[0005] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0006] To address the aforementioned issues, the present invention aims to provide a cube socket with wireless charging functionality, which offers advantages such as simplified wireless charging module installation structure, optimized safety door component design, and improved assembly efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] This application provides a cube-shaped power strip with wireless charging functionality. The technical solution includes a housing and an inner liner assembly disposed within the housing. The inner liner assembly includes a base and a top cover mounted on the base. The base has guide posts at each of its four corners, and a power extraction unit is disposed on the base between adjacent guide posts. The top cover includes a cover plate and legs at its four corners. A wireless charging assembly is fixedly attached to the bottom of the cover plate. When the top cover is fixed to the base, the legs engage with the guide posts, and the wireless charging assembly is located above the base. This technical solution solves the technical problem through the following combination of features: a separate design for the housing and inner liner assembly enables modular assembly; the engagement structure between the guide posts on the base and the legs on the top cover provides precise positioning; the partitioned layout of the power extraction unit and the wireless charging assembly avoids electromagnetic interference; and the direct fixing of the wireless charging assembly to the bottom of the cover plate simplifies the installation process. These features work together to form a compact and easy-to-assemble wireless charging socket solution.

[0009] This solution achieves rapid alignment and installation of the top cover and base through the mechanical cooperation of the guide column and the support leg. At the same time, it uses the cover plate as a carrier platform for the wireless charging component, eliminating the need for additional fixing parts in traditional technology, effectively reducing assembly complexity and improving structural reliability.

[0010] Furthermore, this application also proposes that the support leg is a hollow support leg, and the support leg is sleeved on the guide post.

[0011] Furthermore, this application proposes that the wireless charging component includes a wireless PCB board and a coil disposed on the wireless PCB board; the wireless PCB board is fixed to the bottom of a cover plate, and the coil is located between the wireless PCB board and the cover plate. This involves a direct mounting method where the wireless PCB board is fixed to the bottom of the cover plate, and a sandwich structure where the coil is built into the space between the wireless PCB board and the cover plate. This solution achieves integrated installation by fixing the wireless PCB board and the cover plate together, eliminating the need for additional components such as anti-slip pads and insulating sheets in traditional technologies; simultaneously, the sandwich layout of the coil utilizes the cover plate as a physical support, avoiding the processing complexity of separately creating mounting slots, and also providing protection for the coil through the cover plate. These two features work synergistically to significantly simplify the assembly process while ensuring electrical performance.

[0012] Furthermore, this application proposes that each of the four corners of the wireless PCB board has a notch, and when the wireless PCB board is fixed to the bottom of the cover plate, the support leg is located within the notch. The technical feature of the notch at the corners of the wireless PCB board, together with the assembly relationship of the support leg being located within the notch, constitutes a space-avoidance structure. By providing space for the support leg through the notches, installation misalignment or component deformation caused by rigid contact between the edge of the wireless PCB board and the support leg is avoided, achieving a compact integration of the wireless charging component and the cover structure.

[0013] Furthermore, this application proposes that the top surface of the cover plate has an upwardly protruding boss, and the bottom surface of the cover plate has a groove corresponding to the boss; the coil is embedded in the groove. This technical solution achieves precise positioning and fixation of the coil through the integrally formed boss and groove structure of the cover plate. The corresponding design of the boss and groove forms a physical limiting structure, allowing the coil to be accurately embedded in the groove, avoiding the problem of needing to use additional anti-slip pads, insulating sheets, and other auxiliary fixing components in traditional technologies. The boss structure also provides a fitting point for the through hole on the end face of the shell, realizing the coordinated positioning of the inner liner component and the shell. This solution simplifies the assembly process through the integrated mechanical structure design, improving the reliability and consistency of coil installation.

[0014] Furthermore, this application proposes that multiple end faces of the housing have through holes. When the inner liner assembly is installed inside the housing, the boss on the cover plate is embedded in one of the through holes, and the power-taking unit on the base corresponds to the other through holes. The through holes on the housing end faces, the boss on the cover plate, and the power-taking unit on the base correspond to the remaining through holes. The axial positioning of the inner liner assembly is achieved through the physical engagement of the boss and the through holes, while the spatial correspondence between the power-taking unit and the other through holes ensures accurate exposure of the electrical interface. This solution achieves triple positioning through a mechanical limiting structure: the boss embedding constrains longitudinal displacement, the through hole distribution limits the circumferential angle, and the alignment of the power-taking unit and the through holes ensures precise docking of the functional module with the housing opening. Moreover, the boss on the cover plate being embedded in one of the through holes allows the wireless charging coil to be closer to the housing surface, thereby shortening the sensing distance.

[0015] Furthermore, this application also proposes that the base is provided with an L-polar conductive component, an N-polar conductive component, and an E-polar conductive component, and each of the L-polar conductive component, N-polar conductive component, and E-polar conductive component is provided with an electrode socket for each power-gathering unit; the power-gathering unit includes a power-gathering groove component and a safety door component disposed inside the power-gathering groove component; the safety door component is used to control the opening or closing of the electrode socket.

[0016] Furthermore, this application proposes that the safety door assembly includes a base, a valve plate embedded in a groove in the base, and a reset component acting on the valve plate. The base has holes corresponding to electrode insertion holes. The valve plate is rotatably connected to the center of the base, and extends radially to both sides to form a stop. The upper surface of the stop is an inclined surface facing the direction of rotation. When the reset component applies force, the stop of the valve plate blocks the holes. When the plug is inserted into the power-taking groove component and abuts against the valve plate, the valve plate rotates to avoid the holes, exposing the electrode insertion holes. This solution achieves safety protection through the following structural cooperation: the base provides the installation foundation, and its groove and holes form the valve plate's movement space; the valve plate adopts a central rotation structure, achieving bidirectional shielding through the radially extending inclined stop; the reset component provides a normal closing force; the inclined surface design generates a rotational component force when the plug is inserted. This solution simplifies the traditional multi-component linkage safety door structure through the mechanical cooperation of the rotating valve plate and the inclined surface, while utilizing the self-guiding characteristics of the inclined surface to improve the smoothness of insertion and removal.

[0017] The technical solution replaces the traditional sliding safety door with a rotating valve plate, and uses a single rotating component to achieve synchronous opening and closing of multiple holes. This reduces the number of parts and reduces operating resistance through the automatic alignment function of the inclined surface and the plug, thereby simplifying the structure and improving reliability.

[0018] Furthermore, this application also proposes that the E-polar conductive component includes a U-shaped grounding contact piece, and each power-collecting groove component has two side openings on its side wall, with both ends of the U-shaped grounding contact piece extending into the power-collecting groove component through the side openings.

[0019] As can be seen from the above, the cube socket with wireless charging function provided in this application simplifies the installation of the wireless charging module through the sleeve structure of the guide post and the support leg, and optimizes space utilization through the rotating safety door component, and has the advantages of compact structure and easy assembly.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", and "width" are used interchangeably.

[0032] The orientation or positional relationship indicated by terms such as "degree", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", and "counterclockwise" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of describing this utility model and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] like Figure 1-10 As shown, this embodiment relates to a cube-shaped socket with wireless charging function, including a housing 1 and an inner liner assembly 2 disposed inside the housing 1. The inner liner assembly 2 includes a base 3 and a top cover 4 disposed on the base 3. The base 3 is provided with guide posts 5 at each of its four corners, and a power extraction unit is disposed on the base 3 between two adjacent guide posts 5. The top cover 4 includes a cover plate 7 and support legs 8 disposed at the four corners of the cover plate 7. A wireless charging assembly 9 is fixedly connected to the bottom of the cover plate 7. When the top cover 4 is fixed to the base 3, the support legs 8 are sleeved with the guide posts 5, and the wireless charging assembly 9 is located above the base 3. The guide posts 5 can be cylindrical, prismatic, or conical in shape. The sleeved connection between the support legs 8 and the guide posts 5 includes, but is not limited to, interference fit, threaded connection, or snap-fit ​​connection. The wireless charging assembly 9 is connected to the bottom of the cover plate 7 by adhesive, snap-fit, or screw fixing, and its power supply line can be embedded in a pre-set wiring groove in the cover plate 7.

[0037] This technical solution achieves modular assembly through a split shell 1 and inner liner component 2 design. The socketed structure of the base 3, guide post 5, and upper cover 4 legs 8 provides a mechanical positioning reference, spatially isolating the wireless charging component 9 from the power extraction unit. Specifically, the guide post 5 simultaneously performs positioning and support functions, and the legs 8 automatically correct the installation position of the upper cover 4 during the socketing process, thus eliminating the need for auxiliary positioning components in traditional technologies. The cover plate 7 serves as an integrated load-bearing platform, with its bottom plane directly fixed to the wireless charging unit.

[0038] Compared to the multi-layer stacking installation method in existing technologies, the wired charging component 9 reduces the use of additional components such as anti-slip pads and insulating sheets. Through the partitioned layout of the base 3 and the top cover 4, the power extraction unit and the wireless charging component 9 are physically isolated, effectively reducing the risk of electromagnetic interference. This structure simplifies the 7-8 assembly steps in traditional technology to 3 main processes, improving assembly efficiency by more than 40%.

[0039] In a specific implementation plan, this application further proposes that the support leg 8 is a hollow support leg, which is sleeved on the guide post 5. The hollow support leg structure can be implemented in the following ways: the inner diameter of the support leg 8 forms a transition fit or interference fit with the outer diameter of the guide post 5; an annular reinforcing rib can be provided in the inner cavity of the support leg 8; and a limiting flange can be extended at the bottom of the support leg 8. Variations of the sleeve fit implementation include: a 15° to 30° chamfer at the top of the guide post 5; a buffer washer at the bottom of the inner cavity of the support leg 8; and axial anti-slip textures with a texture depth of 0.1 to 0.3 mm processed on the surface of the guide post 5. This technical solution forms a rigid connection through the geometric constraint of the hollow support leg 8 and the guide post 5. The specific working principle is as follows: the hollow support leg 8 completely encloses the guide post 5, forming a 360° circumferential contact, increasing the contact area by more than three times compared to traditional point contact. The interference fit of the sleeve structure generates radial preload. Compared to the complex structure in the prior art that requires additional anti-slip pads and electrical insulation sheets, this solution improves connection reliability simply by optimizing the structure of the injection molded parts, reduces the assembly process by more than two steps, and avoids the risk of connection failure caused by the aging of auxiliary parts.

[0040] like Figure 5As shown, this application also proposes that the wireless charging component 9 includes a wireless PCB board 10 and a coil 11 disposed on the wireless PCB board 10. The wireless PCB board 10 is fixed to the bottom of the cover plate 7, and the coil 11 is located between the wireless PCB board 10 and the cover plate 7. The wireless PCB board 10 and the cover plate 7 can be fixed by means of adhesive bonding, snap-fit ​​connection, or screw fixing. Among them, the adhesive bonding method preferably uses thermally conductive adhesive, which can both fix and assist in heat dissipation. The snap-fit ​​connection can be provided with protruding claws on the bottom of the cover plate 7, which cooperate with the slots on the edge of the wireless PCB board 10. Screw fixing is achieved by pre-setting threaded posts on the bottom of the cover plate 7, which are aligned and locked with the mounting holes of the wireless PCB board 10. In the sandwich layout of the coil 11, the bottom surface of the cover plate 7 can be provided with an annular groove 14 to accommodate the coil 11, and the depth of the groove 14 matches the thickness of the coil 11. Alternatively, a planar bonding method can be used, and the flatness of the bottom surface of the cover plate 7 can be used to ensure the flatness of the coil 11. The circuit traces of the wireless PCB board 10 can be designed to surround the coil 11, avoiding interference with the magnetic field. This technical solution directly fixes the wireless PCB board 10 to the bottom of the cover plate 7, eliminating the need for traditional mounting slots and anti-slip pads, thus simplifying the assembly process. The coil 11 is built into the structure between the wireless PCB board 10 and the cover plate 7, using the cover plate 7 as a support carrier. This avoids the complex process of separately machining the coil mounting slot and provides physical protection for the coil 11 through the rigidity of the cover plate 7. These two features work together to achieve a compact layout of the wireless charging module while ensuring electrical safety distance. Compared with existing technologies, this solution reduces the number of parts, lowers the assembly precision requirements, and improves the overall reliability of the module through the integrated structure. Specifically, the cover plate 7 simultaneously serves the dual functions of structural support and coil protection, enabling the wireless charging component 9 to maintain a stable working state under vibration or impact conditions.

[0041] In a specific implementation, cutouts 12 are provided at each of the four corners of the wireless PCB board 10. When the wireless PCB board 10 is fixed to the bottom of the cover plate 7, the support legs 8 are located within the cutouts 12. The cutouts 12 can be rectangular, arc-shaped, or trapezoidal in geometry.

[0042] The depth ensures that the support leg 8 is fully accommodated. Specifically, the notch 12 can be formed by stamping or laser cutting and implemented after the PCB board is immersion gold treated, ensuring the conductivity of the edge of the notch 12. This technical solution achieves spatial avoidance through geometric adaptation design. When the wireless PCB board 10 is installed at the bottom of the cover plate 7, the support leg 8 is precisely accommodated in the corner notch 12, thereby eliminating the risk of rigid contact between the edge of the PCB board and the support leg 8 in traditional assembly. Specifically, the notch 12 structure provides directional positioning space for the support leg 8, avoiding misalignment of the guide post 5 due to installation misalignment. At the same time, the non-contact avoidance design prevents the PCB board from deforming under pressure, thus preventing it from affecting the electromagnetic coupling efficiency between the coil 11 and the charging device. Compared with the multi-layer stacking and fixing scheme in the prior art, this design reduces the assembly steps to a single positioning operation while maintaining the same structural strength, significantly improving the production yield.

[0043] like Figure 3-6 As shown, the top surface of the cover plate 7 has an upwardly protruding boss 13, and the bottom surface of the cover plate 7 has a groove 14 corresponding to the boss 13. The coil 11 is embedded in the groove 14. Specifically, the corresponding design of the boss 13 and the groove 14 can be achieved in the following way: the boss 13 adopts a cylindrical or square column structure, and the shape of the groove 14 matches the contour of the boss 13, forming a nested limiting. As a preferred embodiment, the depth of the groove 14 is slightly greater than the thickness of the coil 11, so that the coil 11 is flush with the bottom surface of the cover plate 7 after being embedded. Furthermore, the height of the boss 13 can be designed to be consistent with the depth of the through hole 15 of the housing 1 to ensure no gap when fitted. The embedding method of the coil 11 includes, but is not limited to: fixing with adhesive, pressing in with interference fit, or locking with a snap-fit ​​structure. Thus, this technical solution achieves precise positioning and fixing of the coil 11 through the integrally formed boss 13 and groove 14 structure of the cover plate 7. The corresponding design of the boss 13 and the groove 14 forms a physical limiting structure, allowing the coil 11 to be accurately embedded in the groove 14, avoiding the need for additional auxiliary fixing components such as anti-slip pads and insulating sheets in traditional technologies. Compared with existing technologies, this solution simplifies the assembly process through an integrated mechanical structure design, eliminates the cumulative tolerances caused by stacking multiple components, and improves the reliability and consistency of coil 11 installation. The boss 13 structure also provides a fitting point for the through hole 15 on the end face of the housing 1, realizing the coordinated positioning of the inner liner component 2 and the housing 1, solving the defects of complex installation and insufficient positioning accuracy of wireless charging modules in existing technologies.

[0044] like Figure 1 and 2As shown, multiple end faces of the housing 1 are provided with through holes 15. When the inner liner assembly 2 is installed inside the housing 1, the boss 13 on the cover plate 7 is embedded in one of the through holes 15, and the power-taking unit on the base 3 corresponds to the other through holes 15. Specifically, the distribution position of the through holes 15 on the end faces of the housing 1 must maintain a spatial correspondence with the functional modules of the inner liner assembly 2. As a preferred embodiment, the through holes 15 can be set as circular or rectangular, and their hole diameter is slightly larger than the outer diameter of the boss 13 to achieve a clearance fit. The embedding depth of the boss 13 and the through hole 15 is controlled within the range of 1-3mm, which can ensure longitudinal positioning stability and avoid assembly stress caused by over-insertion. The alignment relationship between the power-taking unit and other through holes 15 is achieved through the cooperation of the guide post 5 on the base 3 and the limiting structure inside the housing 1. The axial height of the guide post 5 must ensure that the center line of the power-taking unit coincides with the center line of the corresponding through hole 15 after the base 3 is installed in place. Therefore, this technical solution achieves a triple positioning function through the mechanical engagement of the boss 13 and the through hole 15: the boss 13 constrains the longitudinal displacement of the inner liner assembly 2 along the axial direction, the circumferential distribution angle of the through hole 15 limits the rotational freedom of the inner liner assembly 2, and the spatial correspondence between the power supply unit and the through hole 15 ensures that the electrical interface is accurately exposed.

[0045] Compared to the solutions in the prior art that rely on multi-layer stacked structures, this design solves the positioning accuracy and functional module alignment problems simultaneously through a single physical limiting structure, eliminating the need for additional adjustment steps during assembly. The design of the cover plate 7 boss 13 embedding through the through hole 15 also reduces the distance between the wireless charging coil 11 and the surface of the housing 1 by 15%-20%, effectively improving energy transmission efficiency.

[0046] like Figure 7-10This application also proposes that the base 3 is provided with an L-polar conductive component 16, an N-polar conductive component 17, and an E-polar conductive component 18, each corresponding to an electrode socket 19 for each power-gathering unit. The power-gathering unit includes a power-gathering groove component 20 and a safety door component 21 disposed inside the power-gathering groove component 20. The safety door component 21 is used to control the opening or closing of the electrode socket 19. Specifically, the L-polar conductive component 16, N-polar conductive component 17, and E-polar conductive component 18 can be made of separate copper alloy stamping parts and fixed inside the base 3 by an insulating bracket. The electrode socket 19 is preferably an elastic contact piece structure, with its opening direction aligned with the insertion path of the power-gathering groove component 20. This technical solution achieves safe power supply for multiple electrodes within a limited space through the coordinated cooperation of modular conductive components and a linked safety door. The separate conductive component layout solves the insulation isolation problem during multi-electrode integration, and the independently configured electrode socket 19 for each power-gathering unit ensures power supply stability. The mechanical linkage design of the safety door assembly 21 enables automatic matching between the socket state and the plug insertion action, thereby completely shielding live parts when not inserted and effectively preventing the risk of accidental contact. Compared with existing technologies, this solution omits the additional electromagnetic locking device and achieves dynamic socket management through a purely mechanical structure, which reduces manufacturing costs and improves system reliability.

[0047] Specifically, the safety door assembly 21 includes a base 22, a valve plate 23 embedded in a groove in the base 22, and a reset component acting on the valve plate 23. The base 22 has a hole 25 corresponding to the electrode insertion hole 19. The valve plate 23 is rotatably connected to the center of the base 22. The valve plate 23 extends radially to both sides to form a stop 26, the upper surface of which is an inclined surface 27 facing the direction of rotation. When the reset component applies force, the stop 26 of the valve plate 23 covers the hole 25. When the plug is inserted into the power-receiving groove component 20 and abuts against the valve plate 23, the valve plate 23 rotates to avoid the hole 25, exposing the electrode insertion hole 19. Specifically, the groove in the base 22 is used to accommodate the valve plate 23 and limit its movement trajectory, wherein the groove depth matches the thickness of the valve plate 23 to ensure rotational stability. The rotatable connection of the valve plate 23 can adopt a pin or ball joint structure, wherein a pin connection is the preferred embodiment, as it has low processing cost and can withstand frequent rotational wear. The inclined angle of the stop 26 and the slope 27 ranges from 15° to 45°. For example, a 30° angle can effectively guide the plug to slide in while avoiding shielding failure due to excessive tilting. The reset component can be a helical spring, torsion spring, or elastic sheet. The design of the torsion spring being mounted on the rotating shaft saves space. The alignment accuracy between the hole 25 and the electrode insertion hole 19 is ensured by the positioning boss during the injection molding of the base 22. Thus, this technical solution solves the problems of complex structure and high operating resistance of traditional sliding safety doors through the mechanical cooperation between the rotating valve plate 23 and the inclined surface 27 and the stop 26. Among them, the rotational movement of the valve plate 23 replaces the multi-part linkage structure, and the synchronous opening and closing of multiple holes is achieved by a single rotating component, reducing the number of parts by more than 40%. The design of the slope 27 automatically generates a rotational component force when the plug is inserted, reducing the operating torque by 35%, while the closing force provided by the reset component ensures safe shielding when not in use. Compared with existing technologies, this solution simplifies the structure and improves the smoothness of insertion and removal through the self-guiding characteristics of the inclined plane 27, reducing the failure rate from 0.5% of the traditional structure to below 0.1%.

[0048] Furthermore, the E-polar conductive component 18 includes a U-shaped grounding contact 28. Each power-collecting recess component 20 has two side openings 29 on its side wall, and both ends of the U-shaped grounding contact 28 extend into the power-collecting recess component 20 through the side openings 29. Specifically, the U-shaped grounding contact 28 can be stamped from phosphor bronze or beryllium copper alloy. Further, the extended ends of the contact can be provided with spherical contacts or wedge-shaped protrusions to enhance the reliability of contact with the plug grounding plate. Thus, this structure allows the grounding contact to achieve two-point contact through lateral extension without occupying the axial space of the power-collecting recess 20. This technical solution utilizes the spatial folding characteristics of the U-shaped structure to achieve bidirectional passage by opening symmetrical openings on the side wall of the power-collecting recess component 20. The extended portions at both ends of the contact form a fit with the side openings 29, ensuring the stability of the mechanical connection and reducing contact resistance by dispersing the contact points. Compared to existing single-point grounding structures, this design doubles the contact area within the same space while avoiding radial interference with the L / N pole components inside the base 3. Specifically, when the plug is inserted, the two ends of the U-shaped contact piece 28 elastically deform simultaneously, forming symmetrical contact pressure.
