Description

Technical Field

[0001] The present invention belongs to the technical field of electrical connectors, and in particular relates to a connector socket and a scooter connector. Background Art

[0002] As an important electrical connection component in electronic equipment, the reliability and stability of electrical connectors directly affect the normal operation of the equipment. Traditional connector sockets usually adopt a structural design in which a center pin and a jack are matched. This structure has obvious defects during long-term use. First, relying solely on the clamping force of the center pin to fix the plug leads to insufficient plugging and unplugging force and poor plugging stability. Secondly, during frequent plugging and unplugging, the matching gap between the center pin and the jack will gradually increase, which can easily cause poor contact or even loosening. In addition, the conductive contact installation structure of the existing connector is single and cannot ensure stable contact with the conductive parts of the plug, affecting the current transmission efficiency. Especially in the application of mobile equipment such as scooters, the problem of poor connector contact is more likely to be aggravated due to vibration and impact during equipment operation.

[0010] Furthermore, a mounting plate is provided at the top of the socket base, and mounting holes are provided on the left and right sides of the mounting plate.

[0011] Furthermore, the present application also proposes a scooter connector, comprising a connector plug and the connector socket as described above, wherein the connector plug comprises a plug base, a center contact sleeve and a plurality of conductive springs;

[0012] A third plugging cavity is provided at the top of the plug base, a second connecting column is provided at the center of the third plugging cavity, a second mounting hole is provided in the second connecting column, and the central contact sleeve is provided in the second mounting hole;

[0014] The outer wall surface of the connector plug is provided with a positioning concave surface corresponding to the positioning convex portion, and the connector plug is positioned and plugged into the connector socket.

[0015] Furthermore, the spring clip mounting groove is an arc-shaped groove, and the conductive spring clip includes an upper connecting block, a bent portion and a lower connecting block. The upper connecting block and the lower connecting block are arc-shaped. When the conductive spring clip is installed in the spring clip mounting groove, the upper connecting block and the lower connecting block are fitted with the spring clip mounting groove, and the bent portion extends into the third plug-in cavity.

[0016] Furthermore, an anti-dropout block is provided on the inner wall of the lower connecting block, and the anti-dropout block abuts against the bottom of the third plug-in cavity to prevent the conductive spring from escaping from the spring installation groove.

[0017] Furthermore, the curved portion includes at least three elastic arms, and a gap is formed between two adjacent elastic arms, and the plurality of elastic arms are arranged along an arc between the upper connecting block and the lower connecting block.

Through the friction between the inner wall of the first plug-in cavity, the outer wall of the second plug-in cavity and the inner wall of the second plug-in cavity and the connector plug, the plug-in and plug-out force of the connector socket and the connector plug is increased, and the power is transmitted stably and the communication connection is established; the part of the connector plug that forms the jack is also inserted in the second plug-in cavity to form a multi-layer nested structure, which not only enhances the connection stability of the connector, but also makes the installation position of the center pin in the socket accurate and the force is evenly distributed, reducing problems such as poor contact caused by structural offset or looseness.

[0021] Several contact mounting grooves are arranged around the outer wall of the first connecting column. The conductor part of the conductive contact is arranged in an arc shape, and multiple conductive contacts are installed therein. The contact mounting grooves pass through the socket base. Such a layout enables multiple conductive contacts to be evenly distributed around the first connecting column. After installation, they are flush with or protrude from the outer wall of the first connecting column and are insulated from each other. When connected to the plug, multiple conductive contacts of different connection circuits can fully contact the corresponding conductive parts of the plug from different angles, thereby increasing the contact area, reducing the contact resistance, and effectively improving the reliability of the connection. Even during the plugging and unplugging process or when subjected to certain external force interference, a good electrical connection state can be maintained, ensuring the stability and accuracy of signal and power transmission.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] In the application of the present invention, the center pin serves as the positive connection end, and after the center pin is plugged into the corresponding center contact sleeve, a positive circuit is formed; at least one conductive contact piece serves as the negative connection end, and after the conductive contact piece is connected to the corresponding conductive elastic piece, a positive circuit is formed; and at least one conductive contact piece serves as the communication connection end, and after the conductive contact piece is connected to the corresponding conductive elastic piece, a communication circuit is formed.

[0042] In existing technologies, electrical connectors generally suffer from insufficient plug-in stability. Traditional charging sockets rely on a single clamping structure with a center pin to secure the plug. In high-frequency charging scenarios, such as scooters, prolonged plugging and unplugging can easily lead to wear of contact components and intermittent power outages between the plug and socket. Especially in outdoor mobile device applications, device vibration exacerbates the risk of radial misalignment of the plug, directly impacting charging efficiency and device safety.

[0043] In order to solve the above problems, this application constructs a multiple contact structure and a mechanical positioning system, attempts to achieve axial stress dispersion through layered plug-in cavities, and at the same time uses annular contact points and positioning structures to enhance radial constraints.

[0044] Please refer to Figure 1-Figure 3 The present application proposes a connector socket 100 including a socket base 10, a center pin 20, and a plurality of conductive contacts 30. A first plug-in cavity 11 is provided at the top of the socket base 10. A first connecting column 13 with a second plug-in cavity 12 is provided at the center of the first plug-in cavity 11. A first mounting hole 14 is provided at the bottom of the second plug-in cavity 12, penetrating the first connecting column 13. The center pin 20 is installed in the first mounting hole 14. The various structures are coaxially arranged. A contact mounting groove 15 penetrating the socket base 10 is provided around the outer wall of the first connecting column 13. A plurality of conductive contacts 30 are installed in the contact mounting groove 15. The first plug-in cavity 11 is provided with a positioning protrusion 16.

[0045] Among them, the first plug-in cavity 11 refers to a cavity for accommodating the main structure of the plug, and its diameter is larger than the first connecting column 13 to form a layered plug-in space. The first connecting column 13 refers to a columnar support located in the center of the plug-in cavity, which can be made of an insulating material integrally formed with the socket base 10, and is used to separate the positive and negative conductive areas. The contact mounting groove 15 refers to a groove distributed circumferentially along the outer side of the first connecting column 13, which can be processed into an arc groove arranged at equal intervals. Its design of passing through the base allows the conductive contact 30 to be inserted vertically from the bottom. The positioning protrusion 16 refers to a protruding structure provided in the first plug-in cavity 11, which can be designed to protrude to the side wall of the first plug-in cavity 11 so that the first plug-in cavity 11 has a D-shaped structure, or designed to be a symmetrically distributed wedge-shaped protrusion for mating with the concave surface of the plug.

[0046] Specifically, when the plug is inserted, it first enters the first plug-in cavity 11, and its outer wall contacts the positioning protrusion 16 to form a radial limit. The internal connecting column of the plug then enters the second plug-in cavity 12, and the sleeve-shaped conductive structure formed by the internal connecting column of the plug forms an axial electrical connection with the center pin 20. The conductive contacts 30 are distributed around the outside of the first connecting column 13. When the plug is fully inserted, the conductive components of the plug form an annular contact area with multiple contacts at the same time. The coaxial structure ensures that the stress is evenly distributed along the axis during the plug-in and unplugging process, avoiding deformation caused by unilateral force. The through design of the contact mounting groove 15 allows the conductive contact 30 to be assembled in the vertical direction, ensuring that the conductive contact 30 is fully fitted with the side wall of the contact mounting groove 15.

[0047] Compared to existing sockets, which rely solely on a single-point clamping mechanism, the present solution utilizes a dual insertion cavity and surrounding contacts to create a dual-fixation mechanism: axial clamping and radial contact. Conventional contacts are often inserted sideways, significantly impacting contact pressure due to assembly accuracy. The present solution's vertical mounting eliminates lateral assembly errors and significantly improves contact stability. The mating of the positioning protrusion 16 with the concave surface of the plug adds a mechanical locking feature to the traditional structure, effectively suppressing radial deviation caused by vibration.

[0048] Through the above technical solution, this application achieves multi-point synchronous contact between the plug and the socket, reducing contact resistance fluctuations. The mechanical positioning structure suppresses radial displacement of the plug, avoiding instantaneous power outages caused by vibration. The vertical installation of the conductive contact 30 simplifies the assembly process and ensures consistent contact pressure. The layered plug-in design distributes plug-in and pull-out stresses to different structural layers, extending the connector's service life.

[0049] The present application further proposes that the contact installation slot 15 is an arc-shaped slot, and the conductor portion 31 of the conductive contact 30 is configured to be arc-shaped. When the conductive contact 30 is installed in the contact installation slot 15 , the conductor portion 31 is flush with the outer wall of the first connecting column 13 .

[0050] The arcuate groove refers to a curved groove structure extending in the circumferential direction, which can be implemented by a circular arc groove structure. Its curvature matches the curvature of the conductive contact 30, and is used to limit the positional displacement of the conductive contact 30 after installation. The conductor portion 31 is flush, which means that the contact surface of the conductive contact 30 forms a continuous plane with the outer wall of the first connecting column 13, which is used to eliminate the height difference between the contact surfaces.

[0051] Specifically, when the conductive contact 30 is constrained within the arcuate slot, its arcuate conductor portion 31 forms surface contact with the inner wall of the contact mounting slot 15, increasing the contact area and reducing deformation caused by localized stress concentration. When the connector plug 200 is inserted, the arcuate conductor portion 31 of the conductive contact 30 creates a uniform pressure distribution on the plug's contact surface, preventing wear or loosening caused by single-point contact. Furthermore, the flush design of the conductor portion 31 with the outer wall of the connecting post eliminates assembly gaps and prevents displacement of the conductive contact 30 due to friction or vibration during plug insertion.

[0052] Compared to existing technologies, traditional contact mounting slots 15 are mostly linear or flat, leaving gaps between the conductive contacts 30 and the slot body. This can easily cause shaking or offset during insertion and removal, leading to increased contact resistance. The curved slots in this application, combined with the curved conductor portion 31, ensure that the contacts maintain a stable fit during insertion and removal, reducing the risk of contact resistance fluctuations.

[0053] Through the above technical solution, the present application solves the problem of unstable contact and easy loosening between the conductive contact 30 and the connector plug 200, ensuring that the conductive contact 30 forms a continuous and stable electrical connection with the contact surface of the plug after the plug is inserted, avoiding the interruption of current transmission due to poor contact, and improving the reliability of the connector under multiple plugging and unplugging conditions.

[0054] The present application further proposes that the first mounting hole 14 includes a first hole section 141 and a second hole section 142 , the inner diameter of the first hole section 141 is larger than the inner diameter of the second hole section 142 , and the second hole section 142 is located at one end of the first connecting column 13 protruding from the bottom end of the socket base 10 .

[0055] The first hole section 141 is the portion of the hole located within the socket base 10 and adjacent to the second insertion cavity 12. Specifically, a stepped hole machining process can be used to create a larger inner diameter structure, which accommodates the larger diameter portion of the center pin 20 and creates an interference fit. The second hole section 142 is the portion of the hole extending into the second insertion cavity 12 within the first connecting post 13. This structure achieves axial positioning of the center pin 20 through precise hole diameter matching. The first connecting post 13 can be specifically formed using an injection molding process, providing insulation between the center pin 20 and the multiple conductive contacts 30.

[0056] Specifically, the two-stage aperture structure generates radial compression through the interference fit between the first aperture section 141 and the larger diameter section of the center pin 20, while the clearance fit between the second aperture section 142 and the smaller diameter section of the center pin 20 creates a guiding constraint. When the center pin 20 is subjected to insertion and removal forces, the inner wall of the second aperture section 142 provides wraparound support for the center pin 20. The transition area between the stepped apertures forms a mechanical stop, preventing the center pin 20 from shifting forward or backward or left or right when subjected to force.

[0057] Compared to existing technologies, the mounting hole of the traditional connector receptacle 100 uses a single-diameter straight hole structure, and the center pin 20 is fixed only by an interference fit, which is prone to gapping under frequent plugging and unplugging conditions. This solution achieves dual positioning constraints through a stepped aperture structure, improving axial positioning stability compared to the traditional straight hole structure.

[0058] Through the above-mentioned technical solution, the present application effectively suppresses radial oscillation of the center pin 20 during insertion, preventing the expansion of the fit gap due to long-term use. The two-stage channel structure, through differentiated aperture design, achieves dual positioning constraints while ensuring assembly efficiency, solving the problem of insufficient positioning in traditional single straight hole structures. The extended design of the protruding end of the connecting column enhances the mechanical strength of the second hole segment 142, preventing deformation of the hole wall due to insertion and extraction forces, and maintaining a stable axial alignment state for the center pin 20.

[0059] The present application further proposes that the center needle 20 includes a first plug-in portion 21 and a second plug-in portion 22, the outer diameter of the first plug-in portion 21 is larger than the outer diameter of the second plug-in portion 22, the first plug-in portion 21 is interference-mounted in the first hole section 141, and the second plug-in portion 22 is positioned and mounted in the second hole section 142 and passes through the second plug-in cavity 12.

[0060] Among them, the first hole section 141 refers to the part with a larger diameter in the stepped hole formed inside the socket base 10, which can be specifically realized by forming a stepped hole structure through mechanical processing, and is used to accommodate the first plug-in part 21 with a larger outer diameter and use interference fit to generate a radial locking force. The second hole section 142 refers to the part with a smaller diameter in the stepped hole, which can be specifically formed through a precision drilling process, and is used to circumferentially limit the second plug-in part 22 to achieve axial positioning. The first plug-in part 21 refers to the outer diameter expansion section of the center needle 20, which is pressed into the first hole section 141 by interference fit to form the main fixed support. The second plug-in part 22 refers to the outer diameter contraction section at the bottom end of the center needle 20, which is inserted into the second hole section 142 through clearance fit to form an auxiliary positioning support.

[0061] Specifically, an interference fit relationship is formed between the first plug-in portion 21 and the first hole section 141. During the assembly process, the pressing force causes the two to undergo radial deformation to form a physical lock, thereby preventing the center needle 20 from being displaced when subjected to axial force. A clearance fit relationship is formed between the second plug-in portion 22 and the second hole section 142, and the precise centering and positioning of the center needle 20 is achieved by utilizing the circumferential constraint of the hole wall on the shaft section. The stepped aperture difference between the first hole section 141 and the second hole section 142 forms a dual fixing mechanism, which provides the main fixing force through the large outer diameter plug-in portion and achieves auxiliary positioning through the small outer diameter plug-in portion. The structure in which the second plug-in portion 22 extends to the second plug-in cavity 12 enables the center needle 20 to obtain two-way support from both the inside and outside of the socket base 10, thereby avoiding deflection and loosening caused by unilateral force.

[0062] Compared to existing technologies, the traditional center pin 20 uses a single interference fit, directly pressed into the equal-diameter mounting hole. This can easily lead to widening of the gap under frequent insertion and removal vibrations. This solution, through the combination of a stepped aperture and a split plug-in structure, creates a multi-stage fixing mechanism while ensuring assembly precision. While the existing center pin 20 relies solely on single-point interference fit, this solution leverages the synergistic effect of the interference fit of the first plug-in portion 21 and the clearance positioning of the second plug-in portion 22, maintaining assembly stability while reducing machining precision requirements.

[0063] Through the above technical solution, the present application effectively prevents the axial displacement and radial deflection of the center needle 20 caused by vibration during long-term use, and solves the loosening problem caused by single-point fixation in the traditional structure.

[0064] The present application further proposes that a mounting plate 17 is provided at the top of the socket base 10 , and mounting holes are provided on the left and right sides of the mounting plate 17 .

[0065] Mounting plate 17 refers to the plate-like structure located at the top of socket base 10. Specifically, it can be integrally molded from metal or engineering plastic, expanding the base's load-bearing area and enhancing the overall structural rigidity. Mounting holes refer to through-holes symmetrically distributed on either side of mounting plate 17. Specifically, they can be drilled or injection molded, and are used to securely connect connector socket 100 to external devices using fasteners such as bolts or screws.

[0066] Specifically, mounting plate 17, an extension of the top of the base, features a planar structure that forms stable contact with the mounting surface of the external device, increasing the load-bearing area and distributing the mechanical load. Symmetrical placement of the left and right mounting holes creates a dual-point fixed support. The preload applied by the fasteners creates a uniform clamping force between the base and the external device, eliminating the risk of displacement due to vibration or external impact. When mounting plate 17 and the base are integrally molded from the same material, structural deformation caused by differences in thermal expansion coefficients is avoided, ensuring the stability of the fixing effect during long-term use.

[0067] Please refer to Figure 1-Figure 7 The present application further proposes a scooter connector, including a connector plug 200 and a connector socket 100. The connector plug 200 includes a plug base 40, a center contact sleeve 50 and a plurality of conductive spring clips 60. A third plug-in cavity 41 is provided at the top of the plug base 40, a second connecting column 42 is provided at the center of the third plug-in cavity 41, a second connecting column 42 is provided in the second connecting column 42, a second mounting hole 43 is provided, and the center contact sleeve 50 is provided in the second mounting hole 43. A plurality of spring clip mounting grooves 44 are provided around the inner wall surface of the third plug-in cavity 41, and the spring clip mounting grooves 44 pass through the plug base 40. A plurality of conductive spring clips 60 are respectively installed in the plurality of spring clip mounting grooves 44. A positioning concave surface 45 corresponding to the positioning protrusion 16 is provided on the outer wall surface of the connector plug 200, and the connector plug 200 is positioned and plugged into the connector socket 100.

[0068] The spring clip mounting groove 44 refers to an arc-shaped groove structure that passes through the plug base 40. Specifically, it can be formed on the plug base 40 using an injection molding process, and is used to fix the conductive spring clip 60 and partially expose it. The through-hole design of the spring clip mounting groove 44 allows the conductive spring clip 60 to be directly exposed to the plug cavity, thereby increasing the contact area. The conductive spring clip 60 refers to a metal conductive component with elastic deformation ability. Specifically, it can be stamped and formed using a copper alloy material, and includes an upper connecting block 61, a bent portion 62, and a lower connecting block 63. The conductive spring clip 60 maintains contact pressure with the conductive contact 30 of the connector socket 100 through elastic deformation. The positioning concave surface 45 refers to a recessed structure provided on the outer wall of the plug base 40. Specifically, it can be formed by machining or mold molding, forming a concave-convex fit with the positioning protrusion 16 of the connector socket 100, thereby limiting the circumferential rotation of the plug and the connector socket 100.

[0069] Specifically, when the connector plug 200 is plugged into the connector receptacle 100, the third plugging cavity 41 is nested within the first plugging cavity 11 of the connector receptacle 100, and the second connecting post 42 is inserted into the first connecting post 13 of the connector receptacle 100 to achieve axial alignment. The center contact sleeve 50 forms a central conductive path with the center pin 20 of the connector receptacle 100, and the curved portion 62 of the conductive spring 60 elastically abuts against the conductive contact 30 of the connector receptacle 100 to form a peripheral conductive path. The through-hole design of the spring mounting slot 44 allows the lower connecting block 63 of the conductive spring 60 to be exposed at the bottom of the plug base 40. The anti-drop block 631 abuts against the bottom of the third plugging cavity 41 to prevent it from falling out. The positioning concave surface 45 cooperates with the positioning protrusion 16 of the connector receptacle 100 to limit the rotation or lateral displacement of the plug after plugging. The synergistic effect of the dual conductive paths and the mechanical positioning structure ensures that the connector plug 200 and the connector receptacle 100 maintain stable contact after multiple plugging and unplugging.

[0070] Compared to existing technologies, traditional connectors rely solely on the clamping force between the center pin 20 and the jack to secure the plug, which can easily lead to poor contact during prolonged insertion and removal. This solution, by adding a peripheral conductive spring 60 and a positioning concave surface 45, creates multiple points of elastic contact and mechanical retention, eliminating the risk of failure at a single contact point. While existing springs are typically enclosed within mounting slots, this solution utilizes a through-type spring mounting slot 44, providing the spring with greater room for deformation and more evenly distributing contact pressure.

[0071] Through the above technical solution, the present application effectively solves the problem of unstable connection between the scooter connector plug 200 and the connector socket 100, preventing loosening due to vibration or wear during insertion and removal, and ensuring stable current transmission. The elastic contact structure can still maintain contact pressure after repeated insertion and removal. The positioning concave surface 45 cooperates with the convex portion to eliminate circumferential offset. The dual conductive path reduces contact resistance and improves connection reliability.

[0072] The present application further proposes that the spring clip mounting groove 44 is an arc-shaped groove, and the conductive spring clip 60 includes an upper connecting block 61, a bent portion 62 and a lower connecting block 63. The upper connecting block 61 and the lower connecting block 63 are arc-shaped. When the conductive spring clip 60 is installed in the spring clip mounting groove 44, the upper connecting block 61 and the lower connecting block 63 are in contact with the spring clip mounting groove 44, and the bent portion 62 extends into the third plug-in cavity 41.

[0073] The arcuate groove refers to an arc-shaped penetrating structure along the inner wall of the third plug-in cavity 41, which is used to limit the installation position and contact direction of the conductive spring 60. The arc-shaped upper and lower connecting blocks 61 and 63 refer to the arc-shaped portions of the conductive spring 60 at both ends that contact the spring installation groove 44, increasing the contact area and improving installation stability. The curved portion 62 extending into the third plug-in cavity 41 refers to the elastic portion protruding outward from the middle of the conductive spring 60. Specifically, it can be formed by multiple elastic arms arranged at intervals, which are used to form elastic contact with the conductive contact 30 in the socket during insertion.

[0074] Specifically, the curved structures of the upper and lower connecting blocks 61 and 63 mate with the curved walls of the spring mounting slot 44, creating surface contact and securing the conductive spring 60, preventing displacement due to vibration or insertion and removal. The multiple spring arms of the curved portion 62 elastically deform under external forces during insertion, maintaining stable contact with the socket's conductive contacts 30. The curved fit of the upper and lower connecting blocks 61 and 63 further limits radial movement of the conductive spring 60, ensuring consistent positioning within the socket cavity.

[0075] Compared with the existing technology, the traditional conductive spring clip 60 adopts a straight groove installation method, which has a small contact area and is easy to loosen, while the arc groove of the present application is combined with the arc connecting block to enhance the fixing effect through surface contact; the traditional spring clip adopts a single spring arm structure, and the contact pressure is unevenly distributed, while the multiple spring arms of the present application are arranged at intervals to disperse the contact stress and improve contact reliability.

[0076] Through the above technical solution, the present application achieves a stable installation of the conductive spring clip 60 on the plug base 40, preventing deflection or falling off during the plugging process; the elastic contact of multiple spring arms ensures the stability of current transmission, while buffering the impact of the plugging and unplugging force on the conductive spring clip 60, thereby extending its service life.

[0077] The present application further proposes that an anti-slip block 631 is provided on the inner wall of the lower connecting block 63 , and the anti-slip block 631 abuts against the bottom of the third plug-in cavity 41 to prevent the conductive spring 60 from escaping from the spring installation slot 44 .

[0078] The anti-slip block 631 is a raised structure provided on the inner wall of the lower connecting block 63, which can be formed by stamping or injection molding. This raised structure forms physical contact with the bottom of the third plug cavity 41 when the conductive spring 60 is inserted into the spring mounting slot 44. This structure prevents the conductive spring 60 from moving axially along the mounting slot by rigidly limiting the contact. The bottom of the third plug cavity 41 refers to the bottom surface of the cavity in the plug base 40 that accommodates the second connecting column 42. This contact surface cooperates with the anti-slip block 631 to form a mechanical limit, withstanding axial forces during insertion and removal.

[0079] Specifically, during installation, the lower connecting block 63 of the conductive spring clip 60 is pressed into the spring clip mounting slot 44, and the anti-slip block 631 moves downward until it contacts the bottom of the third insertion cavity 41. When the connector plug 200 is plugged into the receptacle, the conductive spring clip 60 is subjected to the insertion and removal forces, causing it to tend to move axially. At this point, the reaction force of the anti-slip block 631 against the contact surface of the cavity bottom forms a barrier, preventing the conductive spring clip 60 from further movement. This mechanical limit, combined with the fixed spring clip mounting slot 44, creates a dual constraint, maintaining the positional stability of the conductive spring clip 60 during dynamic insertion and removal conditions.

[0080] Compared to existing technologies, conventional conductive spring clips 60 rely solely on friction generated by their own deformation to secure them, making them prone to displacement or falling off after frequent plugging and unplugging. This solution incorporates an anti-drop block 631 that rigidly abuts against the bottom of the cavity, creating an immovable mechanical stop in the axial direction of the spring clip mounting slot 44, achieving reliable fixation.

[0081] Through the above technical solution, the present application effectively prevents the conductive spring 60 from being separated from the installation slot due to external force during the plugging and unplugging process, avoids poor contact problems caused by the displacement of the spring, and ensures that a stable current transmission path is formed between the connector plug 200 and the socket.

[0082] The present application further proposes that the curved portion 62 includes at least three elastic arms, with a gap formed between two adjacent elastic arms, and the multiple elastic arms are arranged along an arc between the upper connecting block 61 and the lower connecting block 63.

[0083] The term "elastic arm" refers to the elastically deformable strip structure within the conductive spring 60, which can be implemented as a stamped metal sheet. Each elastic arm independently bears the contact pressure during insertion and removal. The term "interval" refers to the unconnected gap between adjacent elastic arms, which can be formed through a blanking process, allowing the elastic arms to deform independently when subjected to force. The term "arc setting" refers to the arrangement of the elastic arms to form a curved trajectory with the insertion direction, which can be implemented using a concentric arc distribution, so that the elastic arms form a continuous contact area during insertion.

[0084] Specifically, when connector plug 200 is inserted into a socket, the spring arms of conductive spring 60 are squeezed by the socket's conductive contacts 30, causing each spring arm to independently bend and deform outward. The presence of spacing prevents interference between the spring arms, evenly distributing the deformation stress across each arm. During insertion, the spring arms, arranged along an arc, sequentially contact the conductive contacts 30, forming an arc-shaped path with multiple points of contact, increasing the contact area. After the plug is removed, the spring arms, relying on their own elasticity, return to their initial position, reducing plastic deformation caused by single-point stress concentration.

[0085] In some specific embodiments, the number of the elastic arms may be two or four.

[0086] Compared with the existing technology, the traditional conductive spring 60 adopts a single spring arm structure, and the elasticity is attenuated due to excessive local stress during the plugging and unplugging process. However, this solution uses a multi-spring arm distributed design to disperse the contact pressure to multiple independent deformation units, eliminate the motion interference between the spring arms through spacing, and reduce the risk of material fatigue.

[0087] Through the above technical solution, the present application enables the conductive spring 60 to maintain stable contact pressure during the plugging and unplugging process, avoiding contact failure caused by overloading of a single spring arm. The synergistic effect of multiple spring arms extends the service life of the conductive spring 60, while the arc-shaped contact path enhances the alignment tolerance between the plug and the socket.

[0088] The present application further proposes that the center contact sleeve 50 includes an elastic clamping portion 51 and a fixing portion 52. The elastic clamping portion 51 is composed of at least two elastic clamping pieces. The top end of the elastic clamping piece is bent and contracted inward, and the bottom end of the elastic clamping piece is connected to the fixing portion 52. The outer peripheral surface of the fixing portion 52 is provided with an annular ridge, and the center contact sleeve 50 is interference-mounted in the second mounting hole 43 through the annular ridge.

[0089] The elastic clamping portion 51 refers to a component that achieves a clamping function through elastic deformation. Specifically, it can be implemented by stamping a metal sheet with rebound properties. The top end bends inward and contracts to form a guide structure, which guides the center pin 20 into the insertion process and generates a radial clamping force. The fixing portion 52 refers to a component used to provide rigid support. Specifically, it can be implemented by a metal sleeve structure with annular ridges. The continuous circumferential distribution of the annular ridges ensures uniform pressure transmission during interference fit installation, avoiding local deformation. The annular ridges refer to an annular structure that is continuously raised along the outer circumference of the fixing portion 52. Specifically, it can be formed by turning or extrusion. It is embedded in the inner wall of the second mounting hole 43 through interference fit to form a mechanical lock, limiting the axial displacement of the center contact sleeve 50.

[0090] Specifically, the top of the elastic clamping piece bends inward to form a tapered entrance. When the center needle 20 is inserted, the elastic clamping piece expands outward and continuously applies radial pressure to keep the contact surface tightly fitted. The annular ridge of the fixing portion 52 has an interference fit with the inner wall of the second mounting hole 43, forming an axial fixed constraint. The bottom end of the elastic clamping piece is rigidly connected to the fixing portion 52 to ensure the stability of the clamping action, while allowing the clamping piece to undergo controllable elastic deformation during the insertion and removal process. The circumferential continuous distribution of the annular ridges causes the inner wall of the mounting hole to bear uniform pressure, avoiding local stress concentration and structural damage.

[0091] This solution utilizes the synergistic effect of the elastic clamping portion 51 and the fixing portion 52. During dynamic insertion, the elastic clamping piece adaptively compensates for gaps, while during static fixation, the annular ridge provides mechanical locking, creating a dual-fixation mechanism. In existing technologies, the elastic clamping structure is typically independent and lacks integrated support with the fixing portion 52. This solution utilizes a bottom-end connection design to constrain the clamping action with a rigid support, preventing fatigue fracture caused by excessive deformation.

[0092] Through the above technical solution, the present application reduces contact resistance during the plug-in process through the clamping of the elastic clamping piece. During long-term use, the mechanical locking of the annular ridge suppresses axial displacement, effectively preventing poor contact caused by vibration or wear during plug-in and plug-out. The linkage design between the elastic clamping piece and the fixing portion 52 not only ensures a continuous and stable clamping force, but also prevents the entire device from loosening due to failure of a single fixing method, ensuring the reliability of the current transmission path.

[0093] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
