Abstract

The application discloses an unmanned electrical automatic connection mechanism, which comprises a fixed end assembly and a movable end assembly. The flexible support seat of the fixed end assembly is elastic, so that the magnetic plug can be self-adaptively adjusted in position relative to the plug mounting seat. The magnetic socket mounting plate of the movable end assembly is floatingly mounted on the socket mounting seat through elastic members, so that the magnetic socket also has a multi-degree-of-freedom position compensation capability in the process of butt joint. The problems of contact misplacement, pin bending or connector damage caused by forced insertion in rigid butt joint are effectively avoided. The whole connection process does not need an external power source to drive the plug-in and pull-out actions, and an operator does not need to exert and control the size and direction of the plug-in and pull-out force. The execution mechanism design is simplified, the connector wear caused by uncontrollable manual plug-in and pull-out force is eliminated, and efficient, repeatable and low-maintenance automatic electrical connection is realized.

Description

Technical Field

[0001] This application relates to the field of electrical connection equipment technology, and in particular to an unmanned assembly electrical automatic connection mechanism. Background Technology

[0002] In the assembly and integration of electrical equipment, electrical connection is a crucial link in realizing power transmission and signal conduction. Currently, the plug and socket connection method widely used in electrical equipment mainly relies on manual operation. Operators need to manually align the plug and socket visually and then apply external force to insert them into place. However, with the rapid development of industrial equipment towards modularization and unmanned operation, more and more application scenarios require electrical connections to be completed automatically without human intervention. Traditional manual insertion methods have significant shortcomings. On the one hand, the limited mating surface of plugs and sockets and the small contact spacing make it easy for positional deviations to occur during manual alignment, leading to contact misalignment, poor contact, or even pin bending. On the other hand, due to the unavoidable machining tolerances and cumulative assembly errors between the structural component base and the electrical mounting base, existing rigid connection structures lack an adaptive error compensation mechanism and cannot automatically correct positional deviations during the docking process, resulting in a high docking failure rate. At the same time, existing plug and socket structures usually do not have independent mechanical guiding and positioning functions. In unmanned assembly scenarios, they cannot rely on the operator's visual judgment and tactile feedback to achieve precise alignment, making it difficult to guarantee successful docking on the first attempt. In summary, existing electrical connection methods have shortcomings in unmanned assembly scenarios, such as difficulty in alignment, lack of error compensation, lack of automatic guidance and positioning, and inability to achieve automatic adsorption connection. These shortcomings make it difficult to meet the technical requirements of unmanned assembly for high efficiency, high reliability, and no human intervention. Summary of the Invention

When the mobile terminal component approaches the fixed terminal component along the docking direction, the magnetic socket and the magnetic plug attract each other under the action of magnetic force to complete the automatic electrical connection.

[0005] In an optional embodiment, the fixed end assembly is provided with a guide member, and the magnetic socket mounting plate is provided with a guide engagement portion that cooperates with the guide member; when the mobile end assembly approaches the fixed end assembly along the docking direction, the guide member is inserted into the guide engagement portion to achieve guiding and positioning.

[0006] In an optional embodiment, the guide is a guide pin, the guide mating part is a guide hole provided on the magnetic socket mounting plate, and the end of the guide is provided with a chamfered or tapered guide section to guide the guide into the guide mating part.

[0007] In an optional embodiment, the guide hole is disposed on the magnetic socket mounting plate, and when the moving end assembly approaches the fixed end assembly along the mating direction, the guide hole is sleeved on the guide pin from top to bottom.

[0008] In an optional embodiment, the elastic element is a spring, and the magnetic socket mounting plate is mounted on the socket mounting base by means of a pin and the spring. The spring is in a pre-compressed state so that the magnetic socket mounting plate can be finely adjusted relative to the socket mounting base under the action of external force.

[0009] In an optional embodiment, the magnetic plug is fixed to the flexible support base by a magnetic plug fixing plate; the magnetic socket is mounted on the magnetic socket mounting plate by a magnetic socket fixing plate.

[0010] In an optional embodiment, the flexible support is cylindrical, and the cylinder wall is elastic, so that the upper end of the flexible support can be finely adjusted relative to the plug mounting base.

[0011] In an optional embodiment, the fixing end assembly further includes a cable fixing plate, which is mounted on the plug mounting base for fixing the cable electrically connected to the magnetic plug.

[0012] In an optional embodiment, the mounting surface of the plug mounting base is provided with a positioning pin hole for assembly and positioning with the structural component base, and the mounting surface of the socket mounting base is provided with a positioning pin hole for assembly and positioning with the electrical mounting base base.

[0013] In an optional embodiment, the contact surfaces of the magnetic plug and the magnetic socket are provided with conductive contacts, and the surface of the conductive contacts is provided with a gold-plated layer or a silver-plated layer.

[0014] Compared with the prior art, the advantages of this application are: The unmanned assembly electrical automatic connection mechanism of this application includes a fixed end assembly and a mobile end assembly. The fixed end assembly includes a plug mounting base, a flexible support base, and a magnetic plug. The plug mounting base is used for assembly with a structural component base, the flexible support base is mounted on the plug mounting base, and the magnetic plug is mounted on the flexible support base. The flexible support base is elastic, allowing the magnetic plug to adaptively adjust its position relative to the plug mounting base. The magnetic plug is used for electrical connection with an external circuit. The mobile end assembly includes a socket mounting base, a magnetic socket mounting plate, and a magnetic socket. The socket mounting base is used for assembly with an electrical mounting base, and the magnetic socket is mounted on the magnetic socket mounting plate. The magnetic socket mounting plate is buoyantly mounted on the socket mounting base via an elastic element. The magnetic socket is used for electrical connection with an external electrical component. When the mobile end assembly approaches the fixed end assembly along the mating direction, the magnetic socket and the magnetic plug attract each other under magnetic force to complete the electrical automatic connection.

[0015] This automated electrical connection mechanism divides the connection system into two parts: a fixed-end component and a moving-end component. The fixed end supports the magnetic plug via a flexible support base, while the moving end uses an elastic element to float the magnetic socket on a socket mounting base. Both ends have adaptive position adjustment capabilities. When the moving-end component approaches the fixed-end component along the mating direction, the magnetic socket and magnetic plug attract each other under magnetic force, automatically completing alignment and electrical connection without manual intervention. This eliminates the reliance on visual alignment and tactile feedback in traditional manual insertion, meeting the core requirement of unmanned assembly for manual intervention-free operation.

[0016] During operation, due to unavoidable machining tolerances and cumulative assembly errors between the structural component base and the electrical mounting base, there is often a deviation between the theoretical and actual alignment positions of the magnetic plug and magnetic socket. In this automatic electrical connection mechanism, the flexible support base of the fixed end component is elastic, allowing the magnetic plug to adaptively adjust its position relative to the plug mounting base. Simultaneously, the magnetic socket mounting plate of the moving end component is buoyantly mounted on the socket mounting base via elastic elements, giving the magnetic socket multi-degree-of-freedom position compensation capabilities during docking. This double-end flexible structure allows the elastic deformation of the flexible support base and the floating stroke of the elastic elements to work together to absorb deviations when radial or angular offsets occur at the moment of docking, guiding the magnetic plug and magnetic socket to automatically approach correct alignment. This effectively avoids problems such as contact misalignment, pin bending, or connector damage caused by forced insertion in rigid docking.

[0017] Once the mobile component enters the effective range of the magnetic force, the magnetic force has an automatic correction characteristic, guiding the plug and socket, even with slight misalignment, to an alignment state with the shortest magnetic path and lowest magnetic resistance. The magnetic force continuously provides axial clamping force, ensuring stable contact of the conductive contacts without the need for additional mechanical locking mechanisms. The entire connection process requires no external power source to drive the insertion and removal actions, nor does it require operators to apply and control the magnitude and direction of the insertion and removal force. This simplifies the design of the actuator and eliminates the connector wear problem caused by uncontrollable manual insertion and removal force, achieving efficient, repeatable, and low-maintenance automatic electrical connection.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a schematic diagram of the structure of the electrical automatic connection mechanism provided in the embodiments of this application; Figure 2 A front view of the electrical automatic connection mechanism provided in an embodiment of this application; Figure 3 Left view of an electrical automatic connection mechanism provided in an embodiment of this application; an unmanned assembly electrical automatic connection mechanism, the electrical automatic connection mechanism including a fixed end component 1 and a moving end component 2; like Figure 1 , Figure 2 and Figure 3 As shown, the fixed-end component 1 and the mobile-end component 2 move closer to or further away from each other along a preset docking direction to achieve automatic electrical connection or disconnection. The fixed-end component 1 and the mobile-end component 2 are respectively assembled on different base structures, and the docking direction is the direction in which the mobile-end component 2 moves towards the fixed-end component 1 and finally achieves electrical conduction.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the fixed end assembly 1 includes a plug mounting base 3, a flexible support base 4, and a magnetic plug 8; the plug mounting base 3 is used for assembly with the structural component base, the flexible support base 4 is mounted on the plug mounting base 3, and the magnetic plug 8 is mounted on the flexible support base 4; the flexible support base 4 is elastic, so that the position of the magnetic plug 8 relative to the plug mounting base 3 can be adaptively adjusted; the magnetic plug 8 is used for electrical connection with an external circuit. like Figure 1 , Figure 2 and Figure 3 As shown, the plug mounting base 3 can be fixed to the structural component base by means of bolt connection, snap-fit ​​or welding. The plug mounting base 3 provides a stable mounting reference surface for the fixed end assembly 1. The flexible support base 4 can undergo elastic deformation when subjected to external force, so that the magnetic plug 8 has a certain floating margin in the radial, axial and angular directions. When the magnetic plug 8 is subjected to lateral force or deflection torque during docking, the flexible support base 4 absorbs the above deviation through its own elastic deformation and returns to the initial state after the external force is eliminated, so that the magnetic plug 8 is always kept within the allowable docking range.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the flexible support base 4 can be implemented using an elastic rubber block, spring assembly, corrugated tube structure, elastic gasket, or a combination of the above structures, as long as it can provide multi-directional elastic floating of the magnetic plug 8 relative to the plug mounting base 3. The magnetic plug 8 is used for electrical connection with an external circuit. The magnetic plug 8 is provided with conductive contacts, which are electrically connected to the wires of the external circuit to realize the transmission of electrical energy or electrical signals. The magnetic plug 8 is also provided with a magnetic element, which is used to generate a magnetic field to create a magnetic attraction with the magnetic socket 14. The magnetic element can be a permanent magnet, an electromagnet, or a combination of a permanent magnet and a magnetic conductor.

[0025] like Figure 5 , Figure 6 as well as Figure 7 As shown, Figure 5 This is a schematic diagram of the structure of the fixed end assembly 1 provided in an embodiment of this application; Figure 6 This is a first structural schematic diagram of the mobile terminal component 2 provided in an embodiment of this application; Figure 7This is a second structural schematic diagram of the mobile terminal component 2 provided in an embodiment of this application; the mobile terminal component 2 includes a socket mounting base 9, a magnetic socket mounting plate 10, and a magnetic socket 14; the socket mounting base 9 is used for assembly with an electrical mounting base base, the magnetic socket 14 is mounted on the magnetic socket mounting plate 10, and the magnetic socket mounting plate 10 is buoyantly mounted on the socket mounting base 9 by means of an elastic member 13; the magnetic socket 14 is used for electrical connection with external electrical components; The socket mounting base 9 can be fixed to the electrical mounting base body by means of bolt connection, snap-fit, or welding, providing a mounting base for the mobile terminal component 2. The elastic element 13 provides the magnetic socket mounting plate 10 with a floating stroke along the docking direction and perpendicular to the docking direction, so that the magnetic socket 14 can be adjusted in position relative to the socket mounting base 9 within a certain range.

[0026] The elastic element 13 can be a compression spring, tension spring, elastic pin, elastic rubber pad, or leaf spring, etc. There can be one or more elastic elements 13, evenly distributed circumferentially along the magnetic socket mounting plate 10 to provide uniform floating support force. The magnetic socket 14 is used for electrical connection with external electrical components. The magnetic socket 14 contains conductive contacts that mate with the conductive contacts of the magnetic plug 8. When the magnetic plug 8 and the magnetic socket 14 are connected, the conductive contacts and the conductive contacts form a stable electrical contact, thereby achieving electrical conduction between the external circuit and the external electrical components. The magnetic socket 14 also contains magnetic elements or magnetic conductors to cooperate with the magnetic elements in the magnetic plug 8 to generate magnetic attraction.

[0027] When the mobile terminal component 2 approaches the fixed terminal component 1 along the docking direction, the magnetic socket 14 and the magnetic plug 8 attract each other under the action of magnetic force to complete the automatic electrical connection.

[0028] When the mobile terminal component 2 moves along the docking direction into the effective magnetic field range of the magnetic plug 8 and the magnetic socket 14, the magnetic force between them begins to exert its effect. The magnetic force generates an axial attraction in the docking direction, driving the magnetic socket 14 and the magnetic plug 8 closer together. Simultaneously, the magnetic force has an automatic centering effect in the radial direction; that is, when there is a radial offset between the magnetic plug 8 and the magnetic socket 14, the magnetic force generates a radial component pointing towards the centering position, guiding them to a coaxial alignment state. Under the continuous action of the magnetic force, the conductive contacts of the magnetic plug 8 and the conductive contacts of the magnetic socket 14 finally come into contact, completing the automatic electrical connection. During the docking process, if there is a positional deviation due to machining tolerances or accumulated assembly errors, the elastic deformation of the flexible support 4 and the floating stroke of the elastic element 13 work together to provide positional compensation space for the magnetic plug 8 and the magnetic socket 14, allowing them to smoothly center and connect under magnetic guidance without the need for external precise alignment control.

[0029] The unmanned assembly electrical automatic connection mechanism of this application includes a fixed end assembly 1 and a moving end assembly 2. The fixed end assembly 1 includes a plug mounting base 3, a flexible support base 4, and a magnetic plug 8. The plug mounting base 3 is used for assembly with a structural component base, the flexible support base 4 is mounted on the plug mounting base 3, and the magnetic plug 8 is mounted on the flexible support base 4. The flexible support base 4 is elastic, allowing the magnetic plug 8 to adaptively adjust its position relative to the plug mounting base 3. The magnetic plug 8 is used for electrical connection with an external circuit. The moving end assembly 2... Component 2 includes a socket mounting base 9, a magnetic socket mounting plate 10, and a magnetic socket 14; the socket mounting base 9 is used for assembly with an electrical mounting base base, and the magnetic socket 14 is mounted on the magnetic socket mounting plate 10. The magnetic socket mounting plate 10 is buoyantly mounted on the socket mounting base 9 via an elastic element 13; the magnetic socket 14 is used for electrical connection with external electrical components; when the moving end component 2 approaches the fixed end component 1 along the mating direction, the magnetic socket 14 and the magnetic plug 8 attract each other under magnetic force to complete the automatic electrical connection.

[0030] This automatic electrical connection mechanism divides the connection system into two parts: a fixed-end component 1 and a moving-end component 2. The fixed end supports the magnetic plug 8 via a flexible support base 4, while the moving end uses an elastic element 13 to float the magnetic socket 14 onto the socket mounting base 9. Both ends have adaptive position adjustment capabilities. When the moving-end component 2 approaches the fixed-end component 1 along the docking direction, the magnetic socket 14 and the magnetic plug 8 attract each other under magnetic force, automatically completing alignment and electrical connection without manual intervention. This eliminates the reliance on visual alignment and tactile feedback in traditional manual insertion, meeting the core requirement of unmanned assembly for manual intervention.

[0031] During operation, due to unavoidable machining tolerances and cumulative assembly errors between the structural component base and the electrical mounting base, there is often a deviation between the theoretical and actual alignment positions of the magnetic plug 8 and the magnetic socket 14. In this automatic electrical connection mechanism, the flexible support base 4 of the fixed end component 1 is elastic, allowing the magnetic plug 8 to adaptively adjust its position relative to the plug mounting base 3. Simultaneously, the magnetic socket mounting plate 10 of the moving end component 2 is buoyantly mounted on the socket mounting base 9 via the elastic element 13, enabling the magnetic socket 14 to also possess multi-degree-of-freedom position compensation capabilities during docking. This double-end flexible structure allows the elastic deformation of the flexible support base 4 and the floating stroke of the elastic element 13 to work together to absorb deviations when there is radial offset or angular deviation at the moment of docking, guiding the magnetic plug 8 and the magnetic socket 14 to automatically approach the correct alignment. This effectively avoids problems such as contact misalignment, pin bending, or connector damage caused by forced insertion during rigid docking.

[0032] Once the mobile component 2 enters the effective range of the magnetic force, the magnetic force has an automatic correction characteristic, guiding the plug and socket, which may have slight misalignment, to an alignment state with the shortest magnetic path and lowest magnetic resistance. The magnetic force continuously provides axial clamping force, ensuring stable contact of the conductive contacts without the need for an additional mechanical locking mechanism. The entire connection process requires no external power source to drive the insertion and removal actions, nor does it require operators to apply and control the magnitude and direction of the insertion and removal force. This simplifies the design of the actuator and eliminates the connector wear problem caused by uncontrollable manual insertion and removal force, achieving efficient, repeatable, and low-maintenance automatic electrical connection.

[0033] like Figure 4 , Figure 8 as well as Figure 9 As shown, Figure 4 Provided for the embodiments of this application Figure 3 Schematic diagram of section AA in the diagram; Figure 8 This is the main view of the mobile terminal component 2 provided in the embodiments of this application; Figure 9 Provided for the embodiments of this application Figure 8 A schematic diagram of the BB cross section is shown. In an optional embodiment, the fixed end assembly 1 is provided with a guide member 12, and the magnetic socket mounting plate 10 is provided with a guide mating part that cooperates with the guide member 12; when the moving end assembly 2 approaches the fixed end assembly 1 along the docking direction, the guide member 12 is inserted into the guide mating part to achieve guiding and positioning.

[0034] In actual docking processes, although magnetic attraction has a certain automatic centering effect, its effective range is limited, and when the initial deviation is large, magnetic force alone may not be able to achieve precise centering within a short stroke. The cooperation between the guide component 12 and the guide mating part is equivalent to introducing a rigid constraint channel before or simultaneously with the magnetic attraction, restricting the movement trajectory of the mobile end component 2 to the preset docking axis, so that the magnetic socket 14 gradually converges the radial deviation as it approaches the magnetic plug 8. This ensures both the initial correction capability under large deviation conditions and the precise centering accuracy under small deviation conditions, allowing the docking process to smoothly transition from coarse positioning to fine positioning, significantly reducing the requirements for the motion control precision of the mobile end component 2, and improving the success rate of docking in unmanned assembly scenarios.

[0035] In an optional embodiment, the guide member 12 is a guide pin 7, the guide mating part is a guide hole provided on the magnetic socket mounting plate 10, and the end of the guide member 12 is provided with a chamfered or tapered guide section to guide the guide member 12 into the guide mating part.

[0036] The arrangement of the chamfered or tapered guide section allows the guide pin 7 to be less than coaxial during the initial insertion into the guide hole. Even if there is a certain radial offset or angular deviation between the guide pin 7 and the guide hole, the beveled surface of the tapered guide section can convert the radial force into a tangential sliding force along the tapered surface, guiding the guide pin 7 to slide into the guide hole along the tapered surface. During the dynamic docking process, the floating allowance of the flexible support 4 and the elastic element 13 allows the tapered guide section to complete the initial engagement of the guide pin 7 with the guide hole before the magnetic plug 8 and the magnetic socket 14 are fully aligned. Then, using the guide pin 7 as a reference, the relative positions of the magnetic plug 8 and the magnetic socket 14 are gradually corrected, ultimately achieving precise alignment and contact of the conductive contacts. The taper angle of the tapered guide section can be configured according to the actual docking stroke and the maximum allowable initial deviation.

[0037] like Figure 5 and Figure 6 As shown, in an optional embodiment, the guide hole is disposed on the magnetic socket mounting plate 10, and when the moving end component 2 approaches the fixed end component 1 along the docking direction, the guide hole is sleeved on the guide pin 7 from top to bottom.

[0038] The downward movement of the mobile component 2 along the docking direction ensures that the guide hole naturally aligns with the guide pin 7 under gravity, eliminating the need for additional flipping or attitude adjustment mechanisms. During docking, the magnetic socket mounting plate 10 moves downward along with the mobile component 2, with the guide hole opening downwards. The guide pin 7 is fixed to the fixed component 1 with its end facing upwards. When the mobile component 2 descends to the point where the guide pin 7 enters the guiding range of the guide hole, the guide hole fits onto the guide pin 7 from top to bottom. The guide pin 7 forms a radial constraint on the guide hole, limiting the degree of freedom of the magnetic socket mounting plate 10 in the horizontal plane. Simultaneously, the downward-facing arrangement of the guide hole allows the mobile component 2 to simply lift in the opposite direction along the docking direction to disengage the guide hole from the guide pin 7 during separation. The separation action is simple and smooth, eliminating the risk of jamming.

[0039] In an optional embodiment, the elastic element 13 is a spring, and the magnetic socket mounting plate 10 is mounted on the socket mounting base 9 by means of a pin and the spring. The spring is in a pre-compressed state so that the magnetic socket mounting plate 10 can be finely adjusted relative to the socket mounting base 9 under the action of external force.

[0040] The spring, acting as the elastic element 13, possesses advantages such as simple structure, controllable elastic coefficient, and long fatigue life. The pin passes through the mating holes on the magnetic socket mounting plate 10 and the socket mounting base 9, providing sliding guidance for the magnetic socket mounting plate 10 along the mating direction while limiting its large displacement and disengagement perpendicular to the mating direction. The spring is sleeved on the pin or arranged around the pin, in a pre-compressed state. That is, the spring applies a certain pre-tightening force to the magnetic socket mounting plate 10 even in its free state, keeping the magnetic socket mounting plate 10 in its initial position when no external force is applied. When the magnetic plug 8 applies lateral or axial force to the magnetic socket 14 during the mating process, the spring is further compressed or extended on the basis of pre-compression, allowing the magnetic socket mounting plate 10 to produce a slight displacement along the pin direction, thereby achieving fine-tuning of the position. The pre-compression ensures that the magnetic socket mounting plate 10 will not wobble due to its own weight or vibration in the non-matting state, while it can float smoothly when subjected to force, taking into account both static stability and dynamic compliance.

[0041] like Figure 5 , Figure 6 As shown, in an optional embodiment, the magnetic plug 8 is fixed to the flexible support base 4 by the magnetic plug fixing plate 5; the magnetic socket 14 is mounted on the magnetic socket mounting plate 10 by the magnetic socket fixing plate 11.

[0042] The magnetic plug fixing plate 5 and the magnetic socket fixing plate 11 provide standardized installation interfaces for the magnetic plug 8 and the magnetic socket 14, respectively. The magnetic plug fixing plate 5 firmly clamps or screws the magnetic plug 8 to the upper end of the flexible support base 4, ensuring that the magnetic plug 8 does not loosen or shift relative to the flexible support base 4 when the flexible support base 4 undergoes elastic deformation, thus ensuring that the posture of the magnetic plug 8 always follows the deformation of the flexible support base 4 synchronously. The magnetic socket fixing plate 11 stably mounts the magnetic socket 14 on the magnetic socket mounting plate 10, ensuring that the magnetic socket 14 maintains a constant relative position with the magnetic socket mounting plate 10 during the floating of the elastic element 13. The introduction of the fixing plates also facilitates the modular replacement of the magnetic plug 8 and the magnetic socket 14. When the conductive contacts wear out or the performance of the magnetic components deteriorates, only the fixing plate needs to be removed to replace the magnetic plug 8 or the magnetic socket 14, without having to disassemble the entire flexible support base 4 or the magnetic socket mounting plate 10, reducing maintenance difficulty and downtime.

[0043] In an optional embodiment, the flexible support base 4 is cylindrical, and the cylindrical wall is elastic, so that the upper end of the flexible support base 4 can be finely adjusted relative to the plug mounting base 3.

[0044] The cylindrical flexible support 4 uses its cylindrical wall as the main load-bearing structure for elastic deformation. When the magnetic plug 8 is subjected to radial offset force during docking, the cylindrical wall undergoes compressive deformation on the force-bearing side and tensile deformation on the opposite side. This causes radial displacement and slight deflection between the upper end of the flexible support 4 and the lower end, i.e., between the end of the flexible support 4 where the magnetic plug 8 is mounted and the end connected to the plug mounting base 3. This allows for adaptive adjustment of the position of the magnetic plug 8. The elastic deformation of the cylindrical structure is symmetrical and uniform in all circumferential directions. Regardless of the radial force received by the magnetic plug 8, the cylindrical wall provides a corresponding elastic response, with no directional stiffness difference. This ensures that the magnetic plug 8 has consistent floating compensation capability in all directions. Furthermore, the axial height of the cylindrical structure can be configured according to the required floating stroke, and the cylindrical wall thickness can be adjusted according to the required elastic stiffness.

[0045] In an optional embodiment, the fixed end assembly 1 further includes a cable fixing plate 6, which is mounted on the plug mounting base 3 and is used to fix the cable electrically connected to the magnetic plug 8.

[0046] During the repeated docking and disengagement processes, the magnetic plug 8 undergoes fine-tuning of its position via the flexible support base 4. The cable electrically connected to the magnetic plug 8 inevitably bends and shifts accordingly. If the cable is in a free-hanging state, repeated bending may lead to fatigue fracture of the conductor, or the cable's movement may interfere with the elastic deformation of the flexible support base 4. The cable fixing plate 6 clamps and fixes the cable near the magnetic plug 8, providing a stable routing path and bending radius constraint for the cable. This allows the cable to follow the movement with a controllable bending shape as the magnetic plug 8 floats, avoiding localized stress concentration. Simultaneously, the cable fixing plate 6 transfers the cable's weight and tension from the magnetic plug 8 and the flexible support base 4 to the plug mounting base 3, preventing the cable's own weight from interfering with the docking posture of the magnetic plug 8. This ensures that the flexible support base 4 only needs to compensate for docking deviations without bearing additional cable load.

[0047] In an optional embodiment, the mounting surface of the plug mounting base 3 is provided with a positioning pin hole for assembly and positioning with the structural component base, and the mounting surface of the socket mounting base 9 is provided with a positioning pin hole for assembly and positioning with the electrical mounting base base.

[0048] In unmanned assembly scenarios, the assembly positional accuracy between the plug mounting base 3 and the structural component base, and between the socket mounting base 9 and the electrical mounting base base, directly affects the initial alignment of the magnetic plug 8 and the magnetic plug 9. By setting locating pin holes on the mounting surface, during assembly, the locating pins are first inserted into the corresponding pin holes on the base to achieve coarse positioning, and then tightened with bolts. This eliminates translational and rotational degrees of freedom during assembly, ensuring a high degree of consistency and repeatability in the installation positions of the plug mounting base 3 and the socket mounting base 9 on their respective bases. The fitting accuracy of the locating pin holes can be selected according to the actual tolerance requirements, choosing a clearance fit or a transition fit, thereby controlling the base assembly error within the compensation range of the flexible support base 4 and the elastic element 13, making the error distribution of the entire connection system reasonable and reliable.

[0049] In an optional embodiment, conductive contacts are provided at the contact surfaces of the magnetic plug 8 and the magnetic socket 14, and the surface of the conductive contacts is provided with a gold-plated layer or a silver-plated layer.

[0050] Conductive contacts are the core contact parts for achieving electrical conduction. Gold plating is chemically stable, resistant to oxidation, and exhibits low and minimally fluctuating contact resistance, making it suitable for scenarios requiring high signal transmission quality or precise low-current contact. Silver plating boasts the highest conductivity among all metals and extremely low contact resistance, making it suitable for high-current transmission or power connection scenarios requiring high conductivity. During magnetic connection, the magnetic plug 8 and magnetic socket 14 are magnetically pressed together, causing the conductive contacts to adhere to each other. The gold or silver plating forms a low-resistance, oxidation-resistant conductive interface on the contact contact surface. Even after repeated docking and disengagement cycles, the contact surface maintains good conductivity, preventing problems such as increased contact resistance, overheating, or even open circuits caused by contact oxidation or contamination. This ensures the reliability and lifespan of the electrical contact mechanism under long-term unattended operation.

[0051] It should be understood that the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.
