Description

Technical Field

[0001] The present invention relates to the technical field of power sockets, and in particular to a polyhedral socket. Background Art

[0002] To accommodate multiple devices, existing polyhedral sockets typically have independent electrical connections on multiple sidewalls of the housing, with each electrical connection configured with separate L-pole, N-pole, and E-pole conductive components. These L-pole and N-pole conductive components often use separate copper components, which presents significant design flaws:

[0003] Structural complexity and high costs are prominent issues. Traditional split copper parts require separate stamping of L-pole and N-pole inserts, which are then spot-welded together after manual or mechanical polarity differentiation. Plastic isolation brackets are also added to prevent short circuits. This process involves multiple steps (stamping, welding, and insulation assembly), requiring specialized molds and high-precision positioning equipment, resulting in high manufacturing costs. The multi-faceted design of the polyhedron socket increases the number of electrode assemblies exponentially, further exacerbating cost pressures.

[0004] Low space utilization is a serious problem. The combination of split copper components and plastic brackets takes up a lot of space, limiting the compactness of the socket design. Especially in polyhedral sockets, the stacking of multi-faceted electrode assemblies results in a bulky housing, making it difficult to adapt to the miniaturization requirements of portable electronic devices. Furthermore, the split structure makes it difficult to achieve coordinated deformation of multiple holes, and densely inserted plugs are prone to exacerbated structural deformation due to stress concentration.

[0005] Inadequate plugging and unplugging stability and maintainability have become technical bottlenecks. The split copper socket relies on rigid material clamping and lacks an elastic reset mechanism. After repeated plugging and unplugging, the copper component is prone to stress fatigue, resulting in a decrease in contact pressure, requiring frequent replacement or repair. While existing technologies attempt to improve clamping force through wavy contacts or thickened copper components, they cannot address the inherent lack of elastic rebound capability of the split structure.

[0006] Traditional split-type electrode assemblies struggle to meet these requirements due to process limitations. For example, while the introduction of plastic isolation brackets prevents short circuits, it weakens the overall flexibility of the conductive assembly. Multi-component assembly fragments internal space, hindering the efficient integration of functional modules. Furthermore, existing safety door structures often utilize independent baffles, and their reset mechanisms are susceptible to deformation of the electrode assembly, posing a risk of false triggering. Furthermore, the use of split U-shaped contacts in grounding assemblies presents challenges in achieving both contact stability and assembly precision.

[0007] Therefore, a new polyhedral socket design is urgently needed. This design optimizes the structure and reduces costs through an integrated electrode assembly, while integrating elastic deformation and self-reset functions to improve plug-in durability, space utilization, and safety performance, making it suitable for high-power fast charging and multi-functional integration scenarios. Furthermore, the coordination between the safety door and grounding components must be resolved to achieve modularization, compactness, and intelligent development of the socket.

[0008] In view of the above problems, the existing technology is in urgent need of improvement. Summary of the Invention

[0009] In order to solve the above problems, the purpose of the present invention is to provide a polyhedral socket with the advantages of simple structure, low cost, high space utilization, good plugging and unplugging stability and easy maintenance.

[0010] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0011] The present application provides a polyhedron socket, and the technical solution is as follows: a polyhedron socket, comprising a shell, wherein the shell has potential points constructed on at least the power-taking side walls on both sides thereof; an L-pole conductive component, an N-pole conductive component and an E-pole conductive component are arranged inside the shell, and the L-pole conductive component, the N-pole conductive component and the E-pole conductive component are constructed with corresponding electrode sockets on each potential point; the L-pole conductive component and the N-pole conductive component both adopt an integrated electrode assembly, comprising two annular electrode sheets integrally formed by elastic conductive material, the two annular electrode sheets are circumferentially connected to form a continuous annular structure, and a plurality of electrode sockets are evenly distributed circumferentially between the two annular electrode sheets; the connection of the annular electrode sheets is designed with pre-compression stress, so that the two annular electrode sheets produce coordinated elastic deformation when the plug is inserted into the electrode socket to radially expand and clamp the metal sheet of the plug, and reset to the initial closed state based on the material rebound characteristics after the plug is pulled out.

[0012] In this solution, the shell and its potential-taking structure provide the physical basis for the access of multiple devices, while providing installation space for internal conductive components. The setting of the L-pole, N-pole and E-pole conductive components realizes the independent power supply requirements of multiple holes. The design of the integrated electrode assembly realizes the coordinated elastic deformation when the plug is inserted and the automatic reset function after unplugging through the circumferential connection and pre-stress design of the two annular electrode sheets, thereby simplifying the structure, reducing costs, and improving plug-in stability and space utilization. The continuous annular structure of the annular electrode sheet and the evenly distributed electrode socket design enable multiple sockets to share the same electrode assembly, further optimizing space utilization and manufacturing costs. The application of elastic conductive materials and pre-stress ensures that the electrode assembly can maintain good clamping force and reset performance after multiple plugging and unplugging.

[0013] Furthermore, the present application proposes that the base body within the housing includes an upper base, a lower base, and a partition located between the upper and lower bases; the L-pole conductive component is disposed between the partition and the upper base, and the N-pole conductive component is disposed between the partition and the lower base; a mounting hole adapted for the electrode receptacle of the L-pole conductive component is formed between the upper end surface of the partition and the upper base, and a mounting hole adapted for the electrode receptacle of the N-pole conductive component is formed between the lower end surface of the partition and the lower base; the electrode receptacle is located within the mounting hole, and the diameter of the mounting hole is slightly larger than the electrode receptacle to allow for coordinated elastic deformation and radial expansion of the electrode receptacle when a plug is inserted. The upper and lower bases form a layered mounting frame, and the partition serves as a polarity isolation layer, forming a double-layer cavity structure. This structure achieves precise positioning of the L-pole and N-pole conductive components through physical isolation, avoiding polarity short circuits; the dimensional coordination of the mounting hole and the electrode receptacle provides redundant deformation space, allowing the integrated annular electrode sheet to fully expand during insertion and removal. The synergistic effect of the features is reflected in the following aspects: the layered cavity structure ensures that the conductive components maintain stable alignment when plugged in and out, while the mounting hole diameter margin releases the elastic deformation space of the electrode sheet. The two together solve the problem of poor contact caused by installation deviation in the traditional split structure.

[0014] This solution optimizes internal space utilization through modular layered design, uses the rigid support of partitions and bases to offset plug-in and pull-out stress, and at the same time, the mounting hole size margin ensures the elastic deformation freedom of the integrated electrode sheet, achieving stable clamping when the plug is inserted and precise resetting after removal.

[0015] Furthermore, the present application proposes that the upper and lower bases are fixed to the partition via a snap-fit ​​structure, and the L-pole conductive assembly and the N-pole conductive assembly are respectively fixed in the corresponding cavities. The snap-fit ​​structure connects the upper and lower bases to the partition; the L-pole conductive assembly and the N-pole conductive assembly are fixed in the corresponding cavities. The snap-fit ​​structure enables quick assembly without tools, ensures a rigid connection between the base and the partition, and prevents the conductive assembly from shifting due to vibration. The split-cavity fixing design maintains the relative position stability of the L-pole and N-pole conductive assemblies through physical isolation, preventing the electrode sockets from being misaligned and affecting the insertion and removal accuracy.

[0016] The mechanical interlocking of the snap-fit ​​structure achieves a secure connection between the base and the partition, simplifying the assembly process while improving the structural integrity; the cavity fixation ensures the positioning accuracy of the conductive components and avoids polarity confusion, thereby solving the problem of poor contact caused by loose assembly of traditional split electrode assemblies.

[0017] Furthermore, the present application also proposes that a safety door assembly is provided inside the shell between the inner side of each potential taking and the electrode socket; the safety door assembly includes a seat body, a valve plate embedded in the groove of the seat body, and a reset component acting on the valve plate; the seat body is provided with holes corresponding to the electrode sockets, the center of the valve plate is rotatably connected to the center of the seat body, and the valve plate extends radially to both sides to form a stop portion, and the upper end face of the stop portion is an inclined surface inclined toward the rotation direction; when the reset component applies force, the stop portion of the valve plate covers the hole; when the plug is inserted into the potential taking and abuts the valve plate, the valve plate rotates to avoid the hole, exposing the electrode socket.

[0018] In this solution, a safety door assembly is installed inside the shell, with the seat providing an installation base, the valve plate achieving a shielding function, and the reset component providing an automatic reset force. The holes on the seat correspond to the electrode sockets to ensure accurate alignment when the plug is inserted. The valve plate is designed with a central rotating connection and a radially extending stop. The inclined surface of the stop facilitates the rotation of the valve plate when the plug is inserted. The reset component keeps the valve plate in a shielded state when no plug is inserted, preventing foreign matter from contacting the electrode socket; when the plug is inserted, the valve plate rotates out of the way to ensure normal power supply. This solution achieves dynamic protection of the electrode socket through a mechanical linkage structure, effectively avoiding the risk of electric shock when not plugged in.

[0019] Furthermore, the present application also proposes that the potential is connected to a power-taking groove component on the side wall of the power-taking; the E-pole conductive component includes a plurality of U-shaped grounding contacts connected end to end into a ring, and each power-taking groove component is provided with two side openings on the side wall, and the two ends of the U-shaped grounding contact extend into the power-taking groove component through the side openings. In this solution, the power-taking groove component serves as the physical carrier of the potential; the annular U-shaped grounding contact realizes a grounding loop shared by multiple potentials; the side openings allow the two ends of the contact to extend into the power-taking groove component to form a contact point. This solution replaces the split grounding component with an annular U-shaped contact, and utilizes the continuity of the annular structure to achieve a unified grounding path for multiple potentials, thereby reducing the number of independent grounding components; the two ends of the contact are directly exposed to the power-taking groove component through the side openings, ensuring reliable contact between the plug metal sheet and the grounding contact. The technical solution transforms the multi-point independent grounding of the traditional split E-pole component into a single-loop collaborative grounding through the integrated design of the annular U-shaped contact, which not only simplifies the internal wiring structure, but also improves the grounding stability through the direct contact between the two ends of the contact in the power-taking groove component. The ring connection method avoids welding nodes and reduces contact resistance; the side opening design enables the contact and plug to form double-point contact, enhancing anti-drift capability.

[0020] Furthermore, the present application also proposes that a weak current interface and / or a wireless charging component is integrated inside the shell; the wireless charging component includes a wireless PCB board and a coil arranged on the wireless PCB board.

[0021] Both the L-pole conductive component and the N-pole conductive component adopt the following structure: at least one of the annular electrode sheets is constructed with an input connector for connecting the input cable, and the input connector is a connecting plate bent back to the other annular electrode sheet, and a wiring through hole is provided on the connecting plate; at least one of the annular electrode sheets is constructed with an output connector for connecting the low-voltage interface and / or the wireless charging component, and the output connector is a wiring through hole formed on the annular electrode sheet.

[0022] The shell integrates the weak current interface / wireless charging component, the structure of the wireless charging component (panel / coil / circuit board), and the input and output connector design of the integrated annular electrode sheet. The input connector is fixedly connected to the strong current input cable through a bent connecting plate, and the output connector directly supplies power to the weak current module through the wiring through-holes on the annular electrode sheet. This solution integrates the strong current input and weak current output functions on the same conductive component through the reuse design of the integrated electrode sheet, eliminating the transfer structure of the traditional split power supply line and simplifying the internal wiring space. The wireless charging component adopts a layered layout of the top panel and the lower circuit, which complements the spatial distribution of the electrode assembly to achieve efficient use of the three-dimensional space.

[0023] The technical solution integrates the input and output connectors of the integrated electrode sheet, directly utilizing the annular electrode sheet as the medium for high-voltage to low-voltage energy transmission. This maintains the original plug-in and clamping functions of the electrode assembly while adding a power distribution function. The wiring through-hole structure of the input and output connectors can be achieved through machining, without the need for additional welding or adapter components. This significantly reduces the complexity of modular integration while ensuring conductive reliability. The overhead layout of the wireless charging component and the lateral distribution of the electrode assembly form a three-dimensional spatial synergy, avoiding interference between functional modules.

[0024] Furthermore, the present application also proposes that the projected shape of the annular electrode sheet is a polygon, and the two annular electrode sheets form the electrode sockets between each adjacent side. The annular electrode sheet adopts a polygonal projected shape, and optimizes the uniformity of the socket distribution through geometric symmetry. The polygonal structure forms a natural gap between the adjacent sides, ensuring that the electrode sockets are evenly arranged along the circumference, avoiding the problem of excessive local stress caused by the concentration of sockets in traditional circular electrode sheets. The two annular electrode sheets form an electrode socket between each side, and the rigid support at the polygonal corners and the elastic deformation of the sides work together to improve the stability of the radial clamping force when the plug is inserted. This solution achieves uniform distribution of sockets and stress dispersion through the design of polygonal electrode sheets, and uses geometric structure to enhance clamping stability while maintaining the elastic reset function of the integrated electrode.

[0025] Furthermore, the present application also proposes that the two annular electrode sheets are connected only by an elastic connecting arm on one side, the elastic connecting arm and the annular electrode sheet are integrally stamped, and the two annular electrode sheets are bent on both sides of the connecting arm to form a clamping structure that is approximately symmetrical in space. The two annular electrode sheets are physically connected by a single elastic connecting arm; the connecting arm and the electrode sheet are integrally stamped; the two electrode sheets form a symmetrically bent clamping structure on both sides of the connecting arm. The synergistic effect of these features is manifested as follows: the integrally stamped elastic connecting arm ensures the synchronization of the deformation of the two electrode sheets, eliminating the assembly error of the split structure; the symmetrical bending structure generates a uniform radial expansion force when the plug is inserted, avoiding unilateral stress concentration; the design simplifies the structure by connecting only by an elastic connecting arm on one side, that is, the two annular electrode sheets and the connecting arm in the middle are integrally formed and can be bent into an integrated electrode; at the same time, the necessary elasticity is maintained so that the clamping force distribution is more consistent with the contact surface shape of the plug metal sheet. Through structural simplification and mechanical optimization, this solution reduces process complexity while improving plug-in stability and contact reliability.

[0026] Furthermore, the present application also proposes that there are at least two elastic connecting arms, which are distributed on the two ends of the same side of the two annular electrode sheets. The two annular electrode sheets are connected at the two ends of the same side by at least two elastic connecting arms. This design increases the number of connecting arms and optimizes their distribution positions, so that the two annular electrode sheets can achieve more uniform stress distribution when the plug is inserted, and can also meet the process requirements of folding the two annular electrode sheets in half. The synergistic effect of multiple connecting arms can improve the symmetry and stability of the clamping structure, avoid the local stress concentration caused by single-point connection, and the problem of insufficient distal clamping force and elastic recovery force, thereby ensuring that the electrode socket maintains a balanced radial expansion force and reset accuracy during the plugging and unplugging process.

[0027] Furthermore, the present application also proposes that the annular surfaces of the two annular electrode sheets are respectively provided with a first protrusion and a second protrusion; the first protrusion is distributed along the circumferential direction, and the first protrusions on the two annular electrode sheets extend in opposite directions relative to each other, and together enclose an electrode socket; the second protrusion is arranged on both sides of the first protrusion, and the surfaces of the first protrusion and the second protrusion form a continuous concave-convex structure, and the second protrusions on the two annular electrode sheets extend in opposite directions relative to each other; the concave-convex structure generates radial expansion through elastic deformation when the plug is inserted to clamp the metal sheet of the plug, and returns to the initial closed state after the plug is pulled out; the first protrusion is located in the middle position of the side of the annular electrode sheet, and the second protrusion is located at the end corner position of the annular electrode sheet.

[0028] The first protrusion and the second protrusion are set on the surface of the two annular electrode sheets. The first protrusion forms the basic structure of the electrode socket through circumferential distribution and back extension design, ensuring the initial positioning when the plug is inserted; the surfaces of the first protrusion and the second protrusion form a continuous concave-convex structure to achieve radial expansion through elastic deformation, thereby enhancing the clamping force on the metal sheet of the plug, and at the same time, the layout of the end angle position optimizes the stress distribution. The synergistic effect of the two is that the first protrusion maintains the stability of the socket structure, and the second protrusion provides dynamic clamping and reset functions, jointly solving the problems of uneven clamping force and poor rebound performance of traditional split electrodes. The above scheme forms a continuous concave-convex structure, which can ensure the clamping force and reset elasticity of the integrated electrode sheet. If the convex-concave texture structure is not designed, the integrated electrode sheet will quickly lose its elasticity after long-term plugging and unplugging. In particular, after the four holes are plugged in at the same time, the reset failure of the integrated electrode sheet socket is faster. This solution uses a combined design of an integrated annular electrode sheet and a raised structure, utilizing the elasticity of the material to achieve adaptive expansion and resetting of the socket, thus avoiding stress concentration and fatigue failure of the split structure. At the same time, the concave-convex structure increases the contact area and improves the durability of plugging and unplugging.

[0029] From the above, it can be seen that the polyhedral socket and its integrated electrode assembly and safety door structure provided in this application simplify the structure, reduce costs, and improve space utilization by adopting an integrated electrode assembly design. At the same time, through the pre-stress design and elastic deformation mechanism, the plug-in stability and maintenance convenience are improved. It has the advantages of simple structure, low cost, high space utilization, good plug-in stability and easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0045] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more, unless otherwise explicitly specified.

[0047] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0049] like Figure 1-14As shown, this embodiment relates to a polyhedral socket, comprising a shell 1, wherein the shell 1 is provided with a potential taking portion 2 on at least the power taking side walls on both sides thereof. An L-pole conductive component 3, an N-pole conductive component 4 and an E-pole conductive component 5 are provided inside the shell 1, and each of the L-pole conductive component 3, the N-pole conductive component 4 and the E-pole conductive component 5 is provided with a corresponding electrode socket 7 on each potential taking portion 2. Both the L-pole conductive component 3 and the N-pole conductive component 4 adopt an integrated electrode assembly, comprising two annular electrode sheets 6 integrally formed from elastic conductive material, the two annular electrode sheets 6 being circumferentially connected to form a continuous annular structure, and a plurality of electrode sockets 7 being evenly distributed circumferentially between the two annular electrode sheets 6. The connection of the annular electrode sheets 6 is designed with pre-stress, so that the two annular electrode sheets 6 produce cooperative elastic deformation when the plug is inserted into the electrode socket 7 to radially expand and clamp the metal sheet of the plug, and return to the initial closed state based on the material rebound characteristics after the plug is pulled out. The joints of the annular electrode sheets 6 are designed with pre-stressed pressure. Specifically, a pre-set compressive force is applied to the joints during the manufacturing process, ensuring that the two annular electrode sheets 6 maintain a closed tendency in their natural state. As a preferred embodiment, the pre-stressed pressure can be achieved through a stamping process, whereby a specific pressure is applied through the mold during the material forming stage to induce plastic deformation at the joints. Furthermore, the elastic conductive material can be phosphor bronze or beryllium copper alloy, which have excellent elastic recovery and electrical conductivity. The continuous ring structure of the annular electrode sheets 6 can be integrally formed by laser cutting or precision stamping, and the uniform circumferential spacing of the electrode receptacles 7 can be adjusted according to the plug specifications. This technical solution replaces the traditional split-type structure with an integrated electrode assembly, addressing the issues of high manufacturing cost and low space utilization. The continuous ring design of the annular electrode sheets 6 allows multiple potential sensors 2 to share the same conductive assembly, reducing the number of parts and assembly steps. The pre-stressed design imparts a self-resetting function to the electrode assembly. When a plug is inserted, the two annular electrode sheets 6 deform in unison to generate a radial clamping force, and automatically return to their original state upon removal, thereby improving plug-in stability and durability. Compared to existing technologies, this solution omits the welding process of separate copper parts and insulating brackets, simplifying the production process while improving contact reliability through elastic deformation. The annular layout of the electrode assembly optimizes space utilization, allowing more functional modules to be integrated within the housing 1.

[0050] like Figure 4-6As shown, the base body 8 inside the shell 1 includes an upper base 9, a lower base 10, and a partition 11 located between the upper base 9 and the lower base 10. The L-pole conductive component 3 is arranged between the partition 11 and the upper base 9, and the N-pole conductive component 4 is arranged between the partition 11 and the lower base 10. A mounting hole 12 that is compatible with the electrode socket 7 of the L-pole conductive component 3 is formed between the upper end surface of the partition 11 and the upper base 9, and a mounting hole 12 that is compatible with the electrode socket 7 of the N-pole conductive component 4 is formed between the lower end surface of the partition 11 and the lower base 10. The electrode socket 7 is located in the mounting hole 12, and the diameter of the mounting hole 12 is slightly larger than the electrode socket 7 to allow the electrode socket 7 to produce a coordinated elastic deformation and radial expansion when the plug is inserted.

[0051] Specifically, the upper base 9 and the lower base 10 can be made by injection molding, and the material used is flame-retardant PC or nylon, and a slot structure for positioning the conductive components is provided inside. The partition 11 is preferably formed as a whole of insulating material, and the edge of the mounting hole 12 is designed to be a rounded transition to avoid stress concentration. The dimensional matching tolerance of the mounting hole 12 and the electrode socket 7 is controlled within a reasonable range, such as within the range of 0.2-0.5mm, which not only ensures the guiding accuracy when the plug is inserted, but also provides sufficient space for the electrode sheet to expand. As a preferred embodiment, an elastic gasket can be provided between the upper base 9 and the partition 11 to compensate for assembly tolerances and buffer the impact of plugging and unplugging. This technical solution realizes modular positioning of the conductive components through a layered cavity structure, in which the partition 11 acts as a rigid support body to transmit the plugging and unplugging stress to the entire shell 1 to avoid local deformation. The size margin design of the mounting hole 12 releases the elastic deformation space of the integrated electrode sheet, so that it can expand evenly to form a stable contact when the plug is inserted. Compared to existing split-body structures, this design eliminates the cumulative errors of multi-component assembly. The coordinated constraints of the base and partition 11 ensure the precise alignment of the electrode socket 7. Furthermore, the dynamic fit between the mounting hole 12 and the electrode socket 7 solves the poor contact problem caused by the lack of deformation space in traditional structures. This improves plug-in / out durability while maintaining a compact structure, ensuring electrical stability during high-power transmission.

[0052] Furthermore, the upper base 9 and the lower base 10 are fixed to the partition 11 through the snap-fit ​​structure 13 , and the L-pole conductive component 3 and the N-pole conductive component 4 are fixed in the corresponding cavities respectively.

[0053] The buckle structure 13 can be implemented in the following ways:

[0054] 1. Such as Figure 5 and 6 As shown, spring hooks are provided on the upper base 9 and the lower base 10, and the spring hooks are provided with bayonets. A clamping block is provided on the side of the partition 11, and the bayonet on the spring hook can be clamped to the clamping block to achieve fixed connection.

[0055] 2. Hook-shaped protrusions are provided on both sides of the partition 11, and slots are provided at corresponding positions of the upper base 9 and the lower base 10. The protrusions and the slots are mechanically interlocked by vertical pressing.

[0056] 3. An elastic latch is provided on the periphery of the partition 11, and an annular groove is provided on the inner wall of the upper base 9 and the lower base 10. The latch is embedded in the groove by rotation and alignment to achieve circumferential fixation.

[0057] 4. A wedge-shaped guide rib is provided on the contact surface between the partition 11 and the base, and an oblique slide groove is provided at the corresponding position of the base. The guide rib and the slide groove are pushed in obliquely to form an interference fit.

[0058] The split-cavity design is achieved by forming a closed L-pole cavity between the upper base 9 and the partition 11, and a closed N-pole cavity between the lower base 10 and the partition 11. Limiting bosses are provided on the sidewalls of the cavities to constrain the displacement of the conductive components. The partition 11 is integrally injection-molded from an insulating material, with positioning grooves molded on its upper and lower surfaces to match the shapes of the L-pole and N-pole conductive components.

[0059] This technical solution achieves a rigid connection between the base and the partition 11 through the mechanical interlocking of the snap-fit ​​structure 13, eliminating the assembly gap caused by traditional screw fixation. The tool-free assembly of the snap-fit ​​structure 13 simplifies the production process, while the split-chamber design ensures the independent positioning of the L-pole and N-pole conductive components through physical isolation. Compared to existing split-type electrode assemblies, this structure effectively suppresses axial movement of the conductive components in vibration environments, avoiding the problem of increased contact resistance caused by loose assembly.

[0060] like Figure 2 and 3As shown in Figure 10, a safety door assembly 14 is provided inside the shell 1 between the inner side of each potential taking device 2 and the electrode socket 7. The safety door assembly 14 includes a base body 15, a valve plate 16 embedded in the groove of the base body 15, and a reset component acting on the valve plate 16. A hole 18 corresponding to the electrode socket 7 is provided on the base body 15, and the center of the valve plate 16 is rotatably connected to the center of the base body 15. The valve plate 16 extends radially to both sides to form a stopper 19, and the upper end face of the stopper 19 is an inclined surface 20 inclined toward the direction of rotation. When the reset component applies force, the stopper 19 of the valve plate 16 covers the hole 18. When the plug is inserted into the potential taking device 2 and abuts the valve plate 16, the valve plate 16 rotates to avoid the hole 18, exposing the electrode socket 7. The base body 15 can be injection molded using insulating engineering plastic, and the groove depth matches the thickness of the valve plate 16 to ensure smooth sliding. The valve plate 16 is preferably made of wear-resistant nylon or POM, and the bevel 20 of the blocking portion 19 is designed to have an inclination angle of 15°-30° to balance the resistance to plug insertion and shielding reliability. The reset component can be a coil spring, a torsion spring or an elastic silicone component, which is installed between the valve plate 16 and the seat body 15 to provide a rotational reset force. The diameter of the hole 18 is slightly larger than the electrode socket 7 to ensure that the conductive component is fully exposed when the plug is inserted. As a preferred embodiment, limiting bosses can be added on both sides of the seat body 15 to prevent the valve plate 16 from excessive rotation and causing reset failure.

[0061] This technical solution achieves dynamic protection of the electrode socket 7 through a mechanical linkage structure. When no plug is inserted, the reset component pushes the valve plate 16 to rotate, so that the stopper 19 completely covers the hole 18 of the seat body 15, effectively isolating external foreign objects from contacting the electrode socket 7. When the plug is inserted, its metal sheet contacts the bevel 20 of the stopper 19. The design of the bevel 20 converts the vertical insertion force into a rotational torque, driving the valve plate 16 to rotate until the hole 18 is fully exposed, ensuring normal power supply. Compared with the existing split safety door, this design adopts an integrated rotating valve plate 16 structure, which avoids the jamming problem caused by multi-component assembly, and the bevel 20 guide mechanism significantly reduces the plug-in and pull-out resistance. The elastic reset characteristics of the reset component ensure that the safety door automatically returns to the shielded state after the plug is pulled out, without the need for manual intervention. As a result, this solution improves the smoothness and durability of the plug-in and pull-out operations while ensuring electrical safety.

[0062] like Figure 3 and 4As shown in Figure 9, this socket adopts a German-style socket structure. The potential 2 is a power-taking groove component 21 connected to the side wall of the power-taking groove. The E-pole conductive component 5 includes multiple U-shaped grounding contacts 22 connected end to end to form a ring. Each power-taking groove component 21 has two side openings 23 on its side wall. The two ends of the U-shaped grounding contact 22 extend into the power-taking groove component 21 through the side openings 23. Specifically, the ring connection of the U-shaped grounding contact 22 can be implemented in the following way: multiple U-shaped contacts are integrally processed into a closed loop structure through a stamping process, and adjacent contacts are connected by an arc-shaped transition section. Alternatively, as shown in the figure, the end corners of two adjacent U-shaped grounding contacts 22 are riveted or welded together with L-shaped connecting pieces to form a closed loop structure. As a preferred embodiment, the contact material is phosphor bronze, which ensures both elasticity and sufficient mechanical strength. The portion of the contact extending into the power-taking groove component 21 can be set in a spherical shape, a wedge shape, or an arc shape to increase the contact area with the metal sheet of the plug. This technical solution replaces the traditional split grounding assembly with an integrated structure of an annular U-shaped contact 22, leveraging the continuity of the annular conductive path to achieve a common ground connection for multiple potential points 2. When a plug is inserted into any power supply groove member 21, the two ends of the contact form a double-point contact with the plug grounding plate through the side opening 23, with contact pressure provided by the elastic deformation of the annular structure.

[0063] Furthermore, the present application also proposes a technical solution of integrating a weak current interface 24 and / or a wireless charging component 25 inside the shell 1. The solution shown in the figure is that the weak current interface 24 and the wireless charging component 25 are integrated inside the shell 1. Among them, the wireless charging component 25 includes a wireless PCB board 26, and a coil 27 arranged on the wireless PCB board 26. As a preferred embodiment, the induction coil 27 of the wireless charging component 25 adopts a planar spiral layout, and its projected area does not exceed the inner diameter range of the annular electrode sheet 6. The circuit board directly obtains the low-voltage direct current after the strong current conversion through the wiring through-hole 35 of the output connector 33. Figure 7 and 8As shown, both the L-pole conductive component 3 and the N-pole conductive component 4 employ the following structure: at least one annular electrode sheet 6 is provided with an input connector for connecting to an input cable. This input connector is bent away from the other annular electrode sheet 6 to form a connecting plate 34, which is provided with a wiring through-hole 35. At least one annular electrode sheet 6 is provided with an output connector 33 for connecting to the weak current interface 24 and / or the wireless charging component 25. This output connector 33 is a wiring through-hole 35 formed directly on the annular electrode sheet 6. In the above embodiment, the bent connecting plate 34 of the input connector can be integrally formed with the annular electrode sheet 6 through a stamping process. The bending angle is preferably 90°-135° to avoid spatial interference between adjacent electrode sheets. The wiring through-hole 35 can be designed as a countersunk hole structure with an aperture adapted to the cable diameter, for example, an M3 threaded hole or a crimped unthreaded hole. The wiring through-hole 35 of the output connector 33 can be formed simultaneously during the stamping of the annular electrode sheet 6. Its location avoids the deformation zone of the electrode receptacle 7 and is preferably located in the non-operating section of the annular electrode sheet 6.

[0064] Therefore, this technical solution integrates the high-voltage input and low-voltage output functions on the same conductive component through the reuse design of the integrated electrode sheet. The input connector realizes the mechanical fixation and electrical connection of the cable through the bent connecting plate 34, and the output connector 33 uses the conductive path of the annular electrode sheet 6 to directly power the low-voltage module, eliminating the adapter structure of the traditional split power supply line. The top panel and the lower circuit of the wireless charging component 25 are arranged in layers, forming a three-dimensional space complement with the laterally distributed electrode components to avoid physical interference between modules. Compared with the existing technology, this solution reduces the use of internal adapter terminals and insulating spacers, simplifying the high-voltage-low-voltage power supply connection structure by about 40%. At the same time, through three-dimensional space collaborative design, the integrated space occupied by the multi-functional module is reduced by more than 35%.

[0065] like Figure 7 and 8 As shown, the projection shape of the annular electrode sheet 6 is a polygon, and the two annular electrode sheets 6 form an electrode insertion hole 7 between each adjacent side. Specifically, the polygonal projection shape includes but is not limited to a regular hexagon, a regular octagon or a square. Figure 7In a preferred embodiment shown, a square is used, with its four sides forming four evenly distributed electrode sockets 7. As a preferred embodiment, a regular hexagonal structure is used, with its six sides forming six evenly distributed electrode sockets 7. The angle between adjacent sides is 120 degrees, thereby ensuring that the sockets are evenly arranged along the circumference. Furthermore, the electrode sockets 7 are formed by the corresponding sides of two annular electrode sheets 6, and the socket width is adjusted by the side spacing. In another embodiment, an arc-shaped transition structure is provided at the polygonal corners to avoid stress concentration. In addition, the material of the annular electrode sheets 6 is phosphor bronze or beryllium copper alloy to ensure elastic deformation capacity and structural rigidity. This technical solution achieves uniform distribution of sockets and stress dispersion through a polygonal geometric structure. The regular spacing formed by the polygonal sides ensures the positioning accuracy of the sockets, and the angular structure provides rigid support to limit excessive deformation. When the plug is inserted, the sides of the two annular electrode sheets 6 cooperate with elastic deformation to produce radial expansion, and the supporting force at the polygonal corners and the elastic force of the sides work together to form a stable clamp.

[0066] Furthermore, the present application also proposes that the two annular electrode sheets 6 are connected only by an elastic connecting arm 28 on one side, the elastic connecting arm 28 and the annular electrode sheet 6 are integrally stamped, and the two annular electrode sheets 6 are bent on both sides of the connecting arm to form a clamping structure that is approximately symmetrical in space.

[0067] Specifically, the width of the elastic connecting arm 28 can be designed to be proportional to the side length of the annular electrode sheet 6 as needed to balance structural strength and elastic deformation capacity. As a preferred embodiment, the connecting arm can be provided with a wavy or zigzag pattern to enhance lateral deformation capacity. The symmetrical angle deviation of the clamping structure formed by bending is controlled within ±5°, thereby ensuring that the expansion angles of the two electrode sheets are consistent when the plug is inserted. Furthermore, the stamping of the connecting arm 28 and the annular electrode sheet 6 can adopt a continuous die-stamping process of copper alloy strip. In this regard, this technical solution eliminates the assembly error of the split electrode assembly through the design of an integrally formed single-sided elastic connecting arm 28. Among them, the elastic modulus of the connecting arm 28 maintains material consistency with the electrode sheet, so that the two electrode sheets produce synchronous radial deformation when the plug is inserted. The symmetrical bending structure makes the clamping force evenly distributed along the circumference of the plug metal sheet, avoiding the unilateral stress concentration phenomenon of the traditional split structure. As a result, while simplifying the structure, it not only ensures the deformation coordination between the electrode sheets, but also improves the contact stability during the plug-in and unplugging process.

[0068] Furthermore, the present application also proposes that there are at least two elastic connecting arms 28, which are distributed on both ends of the same side of the two annular electrode sheets 6. As a preferred embodiment, the two connecting arms 28 are symmetrically distributed at both ends of the side, and the extension direction of each connecting arm 28 is perpendicular to the bending direction of the annular electrode sheet 6. In addition, the number of connecting arms 28 can be expanded to three, two of which are located at both ends and the third is located in the middle of the side to enhance symmetry. In this regard, the working principle of this technical solution is that by arranging at least two elastic connecting arms 28 at both ends of the same side, the two annular electrode sheets 6 form a multi-point elastic support when the plug is inserted. Specifically, when the plug metal sheet enters the electrode jack 7, the two connecting arms 28 are synchronously bent and deformed, driving the two annular electrode sheets 6 to generate a uniform radial expansion force, thereby avoiding the problem of uneven clamping force distribution caused by a single-point connection. Furthermore, since the connecting arms 28 are distributed at both ends of the side, the torque distribution formed by them is more balanced, so that the annular electrode sheet 6 maintains a stable reset accuracy during the plugging and unplugging process. Compared with the existing technology, this design significantly improves the symmetry and durability of the clamping structure by optimizing the number and spatial distribution of the connecting arms 28, while meeting the deformation coordination requirements of the electrode sheet folding process.

[0069] like Figure 7 and 8 As shown, a first protrusion 29 and a second protrusion 30 are respectively provided on the annular surfaces of the two annular electrode sheets 6. The first protrusions 29 are distributed along the circumference, and the first protrusions 29 on the two annular electrode sheets 6 extend in opposite directions, together enclosing an electrode socket 7. The second protrusions 30 are arranged on both sides of the first protrusion 29, and the surfaces of the first protrusions 29 and the second protrusions 30 form a continuous concave-convex structure, and the second protrusions 30 on the two annular electrode sheets 6 extend in opposite directions. The concave-convex structure expands radially through elastic deformation when the plug is inserted to clamp the metal sheet of the plug, and returns to the initial closed state after the plug is pulled out. The first protrusion 29 is located in the middle of the side of the annular electrode sheet 6, and the second protrusion 30 is located at the end corner position of the annular electrode sheet 6.

[0070] Specific implementations of the first protrusion 29 include, but are not limited to, using a protrusion structure with a semicircular, trapezoidal, or triangular cross-section. The second protrusion 30 can be formed by stamping, etching, or laser processing. The surfaces of the first and second protrusions 29, 30, form a continuous concave-convex structure, preferably with a wavy, zigzag, or grid-like texture, to ensure guidance during plug insertion. This technical solution addresses the issue of plugging and unplugging stability through the synergistic effect of the first and second protrusions 29, 30. The first protrusion 29 forms a rigid support frame, maintaining the structural stability of the jack. The second protrusion 30 and the concave-convex structure formed with the first protrusion 29 provide dynamic clamping force through elastic deformation, and their corner layout distributes plugging and unplugging stress. The specific operating process is as follows: When the plug is inserted, the concave-convex structure 31 undergoes elastic deformation, generating a radial expansion force, while the first protrusion 29 limits excessive deformation. Upon removal, the material's rebound force restores the concave-convex structure 31 to its original state. Compared to split-type electrodes, this design offers three improvements: the concave-convex structure and the second protrusions 30 at the corners effectively delay material fatigue, thereby improving plugging and unplugging life. Tests show that under the conditions of simultaneous plugging and unplugging of four holes, the structure can still maintain a reset accuracy of more than 90%.

[0071] like Figure 11-14 As shown, an upper cover 36 is provided on the base body 8. Guide columns 37 are provided on the four end corners of the base body 8, and a potential 2 is provided on the base body 8 between two adjacent guide columns 37. The upper cover 36 includes a cover plate 38 and support legs 39 provided on the four end corners of the cover plate 38. The bottom of the cover plate 38 is fixed with a wireless charging component 25. When the upper cover 36 is fixed to the base body 8, the support legs 39 are socketed with the guide columns 37, and the wireless charging component 25 is located above the base body 8. Among them, the guide columns 37 can adopt a cylindrical, prismatic or conical structure. The socketing method of the support legs 39 and the guide columns 37 includes but is not limited to interference fit, threaded connection or snap connection. The wireless charging component 25 is connected to the bottom of the cover plate 38 by bonding, snap connection or screw fixing, and its power supply line can be embedded in the preset wiring groove of the cover plate 38.

[0072] The socket structure of the guide column 37 of the base body 8 and the support leg 39 of the upper cover 36 in this technical solution provides a mechanical positioning reference, so that the wireless charging component 25 is spatially isolated from the potential collector 2. Specifically, the guide column 37 simultaneously assumes the positioning and support functions, and the support leg 39 automatically corrects the installation position of the upper cover 36 during the socketing process, thereby eliminating the auxiliary positioning components in traditional technology. The cover plate 38 serves as an integrated bearing platform, and its bottom plane directly fixes the wireless charging component 25. Compared with the multi-layer stacking installation method in the existing technology, the use of additional components such as anti-slip pads and electrical insulation sheets is reduced. Through the partitioned layout of the base body 8 and the upper cover 36, the potential collector 2 is physically isolated from the wireless charging component 25, effectively reducing the risk of electromagnetic interference. This structure simplifies the 7-8 assembly steps in traditional technology into 3 main processes, and the assembly efficiency is improved by more than 40%.

[0073] In a specific implementation scheme, the present application also proposes that the support leg 39 is a hollow support leg, and the support leg 39 is sleeved on the guide column 37. The hollow support leg structure can be implemented in the following ways: the inner diameter of the support leg 39 forms a transition fit or an interference fit with the outer diameter of the guide column 37, an annular reinforcing rib can be provided in the inner cavity of the support leg 39, and the bottom of the support leg 39 can be extended to form a limiting flange. Implementation variants of the sleeve fit include: a 15° to 30° lead-in chamfer is provided at the top of the guide column 37. A buffer washer is provided at the bottom of the inner cavity of the support leg 39. Axial anti-slip grooves are machined on the surface of the guide column 37, and the groove depth is 0.1 to 0.3 mm. This technical solution forms a rigid connection through the geometric constraints of the hollow support leg 39 and the guide column 37. The specific working principle is: the hollow support leg 39 completely wraps the guide column 37 to form a 360° circumferential contact, and the contact area is increased by more than 3 times compared with traditional point contact. The interference fit of the sleeve structure generates radial preload. Compared with the complex structure of the background technology that requires additional anti-slip pads and electrical insulation sheets, this solution improves connection reliability by simply optimizing the injection molding structure, reduces the assembly process by more than 2 steps, and avoids the risk of connection failure caused by aging of auxiliary parts.

[0074] like Figure 13As shown, the present application further proposes that the wireless charging assembly 25 includes a wireless PCB 26 and a coil 27 mounted on the wireless PCB 26. The wireless PCB 26 is secured to the bottom of a cover 38, with the coil 27 positioned between the two. The wireless PCB 26 and the cover 38 can be secured by bonding, snap-fitting, or screwing. Adhesive bonding preferably uses thermally conductive adhesive, which both secures the connection and aids heat dissipation. For snap-fitting, a raised claw can be provided on the bottom of the cover 38 to engage with a slot on the edge of the wireless PCB 26. For screw fastening, a threaded post is pre-set on the bottom of the cover 38 to align and lock with the mounting hole of the wireless PCB 26. In the sandwich layout of the coil 27, an annular groove 42 can be provided on the bottom of the cover 38 to accommodate the coil 27. The depth of the groove 42 matches the thickness of the coil 27. Alternatively, a planar bonding method can be employed, where the flatness of the bottom of the cover 38 ensures the flatness of the coil 27. The circuit routing of the wireless PCB 26 can be designed to surround the periphery of the coil 27 to avoid interference with the magnetic field. By directly attaching the wireless PCB 26 to the bottom of the cover 38, this technical solution eliminates the need for conventional mounting slots and auxiliary components such as anti-slip pads, simplifying the assembly process. The coil 27 is built into the structure between the wireless PCB 26 and the cover 38, using the cover 38 as a support carrier. This avoids the complex process of separately machining the coil mounting slot while also providing physical protection for the coil 27 through the rigidity of the cover 38. These two features work together to achieve a compact layout for the wireless charging module while ensuring electrical safety spacing. Compared to existing technologies, this solution reduces the number of components and assembly precision requirements, while also improving the overall reliability of the module through its integrated structure. Specifically, the cover 38 serves as both structural support and coil protection, ensuring that the wireless charging assembly 25 maintains stable operation even under vibration or shock conditions.

[0075] In a specific embodiment, notches 40 are provided at each of the four corners of the wireless PCB 26. When the wireless PCB 26 is secured to the bottom of the cover 38, the legs 39 are positioned within these notches 40. The notches 40 can be rectangular, arcuate, or trapezoidal in shape, with a depth sufficient to fully accommodate the legs 39. Specifically, the notches 40 can be formed by stamping or laser cutting, and applied after the PCB is etched with gold, ensuring the conductive properties of the edges of the notches 40. This technical solution achieves spatial avoidance through a geometrically adaptive design. When the wireless PCB 26 is mounted to the bottom of the cover 38, the legs 39 are precisely accommodated within the corner notches 40, eliminating the risk of rigid contact between the PCB edge and the legs 39 in traditional assembly. Specifically, the notches 40 provide directional positioning space for the legs 39, preventing misalignment in the guide post 37 caused by misalignment. Furthermore, the non-contact avoidance design prevents compression deformation of the PCB board, which could affect the electromagnetic coupling efficiency between the coil 27 and the charging device. Compared with the existing multi-layer stacking fixation solution, this design reduces the assembly steps to a single positioning operation while maintaining the same structural strength, significantly improving production yield.

[0076] like Figure 1 As shown in Figures 11 and 13, the top surface of the cover plate 38 is provided with an upwardly protruding boss 41, and the bottom surface of the cover plate 38 is provided with a groove 42 corresponding to the boss 41. The coil 27 is embedded in the groove 42. Specifically, the corresponding design of the boss 41 and the groove 42 can be achieved in the following manner: the boss 41 adopts a cylindrical or square column structure, and the shape of the groove 42 matches the contour of the boss 41 to form a nested limit. As a preferred embodiment, the depth of the groove 42 is slightly greater than the thickness of the coil 27, so that the coil 27 is flush with the bottom surface of the cover plate 38 after being embedded. Furthermore, the height of the boss 41 can be designed to be consistent with the depth of the through hole 43 of the housing 1 to ensure that there is no gap when embedded. The embedding methods of the coil 27 include but are not limited to: fixing with adhesive, pressing in with interference fit, or locking with a snap-fit ​​structure. Therefore, this technical solution achieves precise positioning and fixation of the coil 27 through the boss 41 and groove 42 structure integrally formed on the cover plate 38. The corresponding design of boss 41 and groove 42 forms a physical retaining structure, allowing coil 27 to be accurately embedded in groove 42, avoiding the need for additional auxiliary fixing components such as anti-slip pads and electrical insulation sheets in traditional technologies. Compared with existing technologies, this solution simplifies the assembly process through the integrated mechanical structure design, eliminates the cumulative tolerances caused by the stacking of multiple components, and improves the reliability and consistency of coil 27 installation. The boss 41 structure also provides a fitting location for the through hole 43 on the end face of the housing 1, achieving the coordinated positioning of the liner assembly 44 and the housing 1, solving the problems of the existing wireless charging module, which is complex to install and lacks positioning accuracy.

[0077] like Figure 1 and 2As shown, through holes 43 are provided on multiple end faces of the shell 1. When the liner assembly 44 is installed inside the shell 1, the boss 41 on the cover plate 38 is embedded in one of the through holes 43, and the potential taking 2 on the base body 8 corresponds to the other through holes 43. Specifically, the distribution position of the through holes 43 on the end face of the shell 1 needs to maintain a spatial correspondence with the functional module of the liner assembly 44. As a preferred embodiment, the through hole 43 can be set to be circular or rectangular, and its aperture size is slightly larger than the outer diameter of the boss 41 to achieve a clearance fit. The embedding depth of the boss 41 and the through hole 43 is controlled within the range of 1-3mm, which can not only ensure the longitudinal positioning stability, but also avoid the assembly stress caused by excessive insertion. The alignment relationship between the potential taking 2 and the other through holes 43 is achieved by the cooperation of the guide column 37 on the base body 8 and the internal limiting structure of the shell 1, wherein the axial height of the guide column 37 needs to ensure that the center line of the potential taking 2 coincides with the center line of the corresponding through hole 43 after the base body 8 is installed in place. Therefore, this technical solution realizes a triple positioning function through the mechanical engagement of the boss 41 and the through hole 43: the boss 41 constrains the longitudinal displacement of the liner assembly 44 along the axial direction, the circumferential distribution angle of the through hole 43 limits the rotational freedom of the liner assembly 44, and the spatial correspondence between the potential 2 and the through hole 43 ensures that the electrical interface is accurately exposed. Compared with the solution that relies on a multi-layer stacking structure in the background technology, this design solves the positioning accuracy and functional module alignment problems simultaneously through a single physical limiting structure, and no additional adjustment steps are required during the assembly process. The design of the boss 41 of the cover plate 38 embedded in the through hole 43 also shortens the distance between the wireless charging coil 27 and the surface of the shell 1 by 15%-20%, effectively improving the energy transmission efficiency.
