Description
Technical Field
[0001] This invention belongs to the field of electrical connector technology, specifically relating to charging connectors and scooter charging equipment. Background Technology
[0002] Electrical connectors, as crucial electrical connection components in electronic devices, directly impact the normal operation of these devices due to their reliability and stability. Traditional scooter connectors typically employ a design where a center pin mates with a terminal, a structure with significant drawbacks over long-term use. First, relying solely on the clamping force of the terminal on the center pin to secure the adapter plug results in insufficient insertion and extraction force, leading to poor connection stability. Second, during frequent insertion and removal, the gap between the center pin and the terminal gradually increases, easily causing poor contact or even loosening. Furthermore, the existing connector's simple contact plate mounting structure cannot ensure stable contact between the adapter plug and the battery socket, affecting current transmission efficiency. This is particularly problematic in mobile applications such as scooters, where vibrations and impacts during operation exacerbate connector contact issues. The lack of effective separation structures and positioning fit designs in current technology makes it difficult to guarantee precise alignment and stable contact of multiple connection terminals, and also fails to effectively prevent connector loosening and detachment under vibration. These problems severely affect the reliability and safety of charging connectors. Therefore, existing technologies urgently need improvement to address these issues. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0034] Please refer to Figures 1-4This application proposes a charging connector, including a power-consuming base 100 and a power-supply base 200; the power-consuming base 100 has an open receiving cavity 1, and the power-supply base 200 is movably connected in the receiving cavity 1; a partition plate 2 is provided at the bottom of the receiving cavity 1 to form a plurality of insertion slots 3, and pins 7 are installed at the bottom of the insertion slots 3; the end of the power-supply base 200 forms a partition groove 4 corresponding to the partition plate 2, so that the end forms a plurality of insertion parts 5, and the insertion parts 5 are embedded with connection terminals 6; when the insertion parts 5 are inserted into the insertion slots 3 from the open, the pins 7 are embedded in the connection terminals 6.
[0035] Among them, the partition plate 2 refers to the isolation component perpendicular to the bottom of the accommodating cavity 1, which is used to divide a single cavity into independent plug-in areas to avoid short circuits between adjacent terminals; the plug-in groove 3 refers to the independent space formed by the partition plate 2, which can be implemented by a groove with a width slightly larger than the plug-in part 5, and the first mounting hole 31 set at the bottom of the groove is used to fix the axial position of the pin 7; the partition groove 4 refers to the groove structure at the end of the power supply base 200 corresponding to the partition plate 2, which can be implemented by a groove matching the thickness of the partition plate 2, so that the plug-in part 5 forms an independent contact unit, which refers to the split protrusion structure at the end of the power supply base 200, each protrusion carrying an independent connection terminal 6, realizing multi-contact synchronous contact.
[0036] Specifically, when the power supply base 200 is inserted into the power consumption base 100, the partition plate 2 is embedded in the partition groove 4 to form a physical limit, so that the plug part 5 is accurately aligned with the plug groove 3; after the plug part 5 enters the plug groove 3, the inner wall of the connecting terminal 6 and the outer surface of the pin 7 form a circumferential contact; the cooperation between the partition plate 2 and the partition groove 4 suppresses the displacement of the plug part 5.
[0037] This solution achieves mechanical limiting through the nested structure of the insertion slot 3 and the insertion part 5, making the contact pressure distribution between the connecting terminal 6 and the pin 7 more uniform during insertion and removal. Through the above technical solution, this application realizes the self-alignment function during the insertion process, reducing the risk of poor contact caused by plug misalignment. The cooperation between the insertion part 5 and the insertion slot 3 disperses the insertion and removal stress, extending the elastic life of the connecting terminal 6. The synergistic effect of the mechanical limiting structure and the electrical contact structure enables the connector to maintain a stable conductive path under vibration conditions.
[0038] This application further proposes that the partition plate 2 is Y-shaped to divide the accommodating cavity 1 into three insertion slots 3, the bottom of the insertion slot 3 is provided with a first mounting hole 31; the end of the insertion part 5 is provided with a second mounting hole 51, and the connecting terminal 6 is embedded in the second mounting hole 51.
[0039] Among them, the Y-shaped partition plate 2 refers to a plate-like structure with three extended branches. Specifically, it can be integrally formed with the bottom of the accommodating cavity 1 by injection molding process. The three branches divide the accommodating cavity 1 into three independent insertion slots 3, forming a stable partition structure. The first mounting hole 31 refers to a through hole set at the bottom of the insertion slot 3. It achieves interference fixation by cooperating with the pin 7 through the inner wall of the hole. The second mounting hole 51 refers to a through hole set at the end of the insertion part 5. Embedded setting means that the connecting terminal 6 is completely embedded in the second mounting hole 51. Specifically, the connecting terminal 6 can be pressed into the second mounting hole 51 by press-fitting process, so that the outer surface of the terminal forms a tight contact with the hole wall.
[0040] This solution forms three independent insertion slots 3 through a Y-shaped partition plate 2, which enables each insertion part 5 to be precisely guided during insertion, solving the problem of inaccurate alignment between the terminal and the pin 7 during insertion, and maintaining a stable electrical contact state even in a vibration environment.
[0041] This application further proposes that the first mounting hole 31 is a stepped hole, and the outer side of the pin 7 is provided with an annular protrusion 701, and the pin 7 is interference-fitted into the first mounting hole 31.
[0042] Among them, the stepped hole refers to a hole structure with a stepped diameter, which can be formed by two cylindrical holes of different diameters connected coaxially, and the axial displacement of the pin 7 is restricted by the stepped structure; the annular protrusion 701 refers to an annular protrusion structure surrounding the outer wall of the pin 7, which can be formed by stamping or turning, and radial positioning is achieved by the fit between the annular protrusion 701 and the stepped hole; the interference fit refers to the assembly method in which the outer diameter of the pin 7 is slightly larger than the inner diameter of the first mounting hole 31, which can be achieved by pressing or thermal expansion and contraction process, and the gap between the pin 7 and the mounting hole is eliminated by the interference fit.
[0043] Specifically, a stepped hole is machined at the bottom of the insertion slot 3 of the power terminal base 100. The small diameter section of the stepped hole forms an interference fit with the outer diameter of the pin 7. When the pin 7 is pressed into the stepped hole, the annular protrusion 701 on its outer wall contacts the stepped surface of the stepped hole, forming an axial limit. The radial pressure generated by the interference fit causes friction between the pin 7 and the first mounting hole 31, preventing the pin 7 from axially moving or rotating circumferentially during use.
[0044] Through the above technical solutions, this application effectively solves the problem of poor contact caused by loosening of the pin 7 during long-term insertion and removal, and enhances the mechanical stability and electrical connection reliability of the charging connector; the stepped hole structure reduces the processing difficulty, and the combination design of the annular protrusion 701 and the interference fit simplifies the assembly process while significantly improving the vibration resistance of the pin 7.
[0045] This application further proposes that the second mounting hole 51 is a stepped hole, and the outer side of the connecting terminal 6 is provided with an annular protrusion 701, and the connecting terminal 6 is interference-fitted into the second mounting hole 51.
[0046] Among them, the stepped hole refers to the mounting hole structure with a stepped change in diameter. Specifically, it can be achieved by coaxially connecting two cylindrical holes of different diameters, and the limiting structure is formed by the change in hole diameter; the annular protrusion 701 refers to the annular protrusion structure surrounding the outer wall of the connecting terminal 6. Specifically, it can be formed by stamping or turning, and is used to form an interference fit with the inner wall of the stepped hole; interference fit means that the outer diameter of the connecting terminal 6 is slightly larger than the inner diameter of the second mounting hole 51. Specifically, it can be achieved through tolerance fit design, so that the connecting terminal 6 produces radial elastic deformation after being pressed into the mounting hole.
[0047] Specifically, a stepped hole with a large-diameter section and a small-diameter section is machined at the end of the plug-in portion 5 of the power supply base 200, and an annular protrusion 701 is machined on the outside of the connecting terminal 6. When the connecting terminal 6 is pressed into the second mounting hole 51, the annular protrusion 701 and the end face of the large-diameter section form an axial limit. The frictional force generated by the interference fit can prevent the connecting terminal 6 from axial displacement during the insertion and removal process, ensuring the contact stability between the terminal and the pin 7.
[0048] Through the above technical solution, this application effectively solves the displacement problem of the connection terminal 6 caused by vibration or frequent insertion and removal, enhances the mechanical locking effect between the terminal and the mounting hole, ensures the stability of current transmission during charging connection, and extends the service life of the connector.
[0049] Please refer to Figures 4-5 This application further proposes that the end of the power supply base 100 away from the receiving cavity 1 is provided with a first positioning post 8, and the outer side of the first positioning post 8 is provided with a first arc-shaped groove 801 coaxial with the first mounting hole 31, and the end of the pin 7 is received in the first arc-shaped groove 801; the end of the power supply base 200 away from the plug-in part 5 is provided with a second positioning post 9, and the outer side of the second positioning post 9 is provided with a second arc-shaped groove 901 coaxial with the second mounting hole 51, and the end of the connecting terminal 6 is received in the second arc-shaped groove 901.
[0050] The first positioning post 8 refers to a columnar structure located at the end of the power supply base 100 away from the receiving cavity 1, used to constrain the position of the end of the pin 7; the first arc-shaped groove 801 refers to an arc-shaped groove opened along the outer circumference of the first positioning post 8, whose axis coincides with the axis of the first mounting hole 31, so that the end of the pin 7 can be accurately positioned during insertion; the second positioning post 9 refers to a columnar structure located at the end of the power supply base 200 away from the insertion part 5, used to fix the end of the connecting terminal 6; the second arc-shaped groove 901 refers to an arc-shaped groove opened along the outer circumference of the second positioning post 9, whose axis coincides with the axis of the second mounting hole 51, ensuring that the end of the connecting terminal 6 remains aligned during insertion.
[0051] This application further proposes that the accommodating cavity 1 of the charging connector is provided with a positioning surface 101 on the side wall so that the accommodating cavity 1 is D-shaped, and the outer side of the power supply base 200 is provided with a positioning cut surface. When the power supply base 200 is inserted into the accommodating cavity 1, the positioning cut surface and the positioning surface 101 cooperate to form a positioning structure.
[0052] The positioning surface 101 refers to the planar structure of the side wall of the accommodating cavity 1, which forms a D-shaped cross-section through the combination of plane and curved surface, and is used to restrict the rotational degree of freedom of the power supply base 200. The D-shaped accommodating cavity 1 refers to a cavity structure with a cross-section in the shape of the letter "D". Its arc part and planar part together form an asymmetrical geometry, which is used to provide directional insertion guidance. The positioning tangent refers to the planar area of the outer wall of the power supply base 200. This plane forms a surface contact fit with the positioning surface 101 of the accommodating cavity 1, which is used to realize angular positioning during the insertion process.
[0053] Specifically, when the power supply base 200 is inserted into the receiving cavity 1 of the power consumption base 100, the positioning cut surface and the positioning surface 101 of the receiving cavity 1 form a surface contact constraint. Due to the asymmetric characteristics of the D-shaped structure, the power supply base 200 can only be fully inserted at a specific angle. The correspondence between its insertion part 5 and the insertion slot 3 is precisely calibrated through planar fit. During the insertion process, the positioning cut surface slides along the positioning surface 101 until it reaches the insertion endpoint. At this time, the insertion part 5 and the insertion slot 3 form a fully fitted state, and the connecting terminal 6 and the pin 7 are precisely aligned.
[0054] This solution eliminates the rotational freedom during the insertion process by using a D-shaped cavity and a positioning surface, ensuring that each insertion maintains a fixed angle and orientation, and avoiding poor contact caused by rotational misalignment.
[0055] Through the above technical solution, this application effectively solves the technical defect of the non-fixed insertion position of traditional connectors. By using a mechanical limiting structure to achieve unique determination of the insertion angle, it not only improves the accuracy of insertion operation, but also prevents electrical connection failure caused by rotational misalignment, and significantly improves the working reliability of the connector in vibration environment.
[0056] Please refer to Figures 1-4 This application further proposes that the pin 7 in the charging connector includes at least one positive pin 71 and at least one negative pin 72; or, the pin 7 includes a positive pin 71, a negative pin 72 and a signal pin 73.
[0057] Among them, the positive electrode pin 71 is a conductive component used to transmit positive current, which can be made of copper alloy into a cylindrical structure and serves as the main current path during charging; the negative electrode pin 72 is a conductive component used to transmit reverse current, which can be made of copper alloy cylindrical structure symmetrically arranged with the positive electrode pin 71 to form a complete current loop; the signal pin 73 is a conductive component used to transmit control signals or status detection signals, which can be made of gold-plated metal pin structure with independent insulation, to realize charging status monitoring or data transmission functions.
[0058] Specifically, in the charging connector structure, when at least one positive terminal pin 71 and at least one negative terminal pin 72 are used, multiple positive and negative terminal pins 7 can be arranged in parallel to improve current carrying capacity. For example, the number of positive terminal pins 71 can be two, and the number of negative terminal pins 72 can be set to two accordingly. By increasing the number of contact points, the current density of a single contact surface is reduced. When a three-pin combination of positive, negative, and signal pins 73 is used, the positive and negative terminal pins 7 undertake the power transmission function, and the signal pins 73 are connected to an external controller through an independent channel to provide real-time feedback of charging voltage or temperature data. During the insertion process, all pins 7 form multi-point contact with the connection terminal 6 through the insertion slot 3 to avoid circuit interruption due to the failure of a single contact point.
[0059] This solution achieves current shunting or functional expansion within the same plug space by arranging multiple pins in parallel or adding independent signal channels, thereby improving the redundancy of physical connections and providing data interaction capabilities for charging control.
[0060] Through the above technical solution, this application effectively solves the problem of insufficient current carrying capacity caused by single-point contact in traditional connectors. The multi-pin 7 structure makes the contact resistance distribution more uniform and reduces the risk of local heating. The added signal pin 73 enables the charging process to have status monitoring function, avoids safety hazards caused by overvoltage or overheating, and at the same time meets the data transmission requirements of smart devices for charging control.
[0061] This application further proposes that both the power supply base 100 and the power supply base 200 are injection molded from insulating materials, and the distance between two adjacent pins 7 is greater than or equal to 3mm.
[0062] Among them, the injection molding of insulating materials refers to the process of processing insulating polymer materials into a base with a specific structure through injection molding. Specifically, engineering plastics such as polycarbonate or nylon can be used. This process can ensure the overall insulation performance of the base and form a complex cavity structure. Among them, the pin spacing of 7 is greater than or equal to 3mm, which refers to the minimum air gap distance between adjacent conductive parts. Specifically, it can be achieved by adjusting the distribution position of the insertion slots 3. This spacing design can effectively prevent arc discharge between conductors of different polarities.
[0063] Specifically, the power supply base 100 and the power supply base 200 are manufactured by injection molding. The material selected is a high-molecular polymer with high insulation strength, such as polycarbonate. The cavity 1, the partition plate 2 and the insertion groove 3 are formed in one step in the mold. During the injection molding process, the mold cavity is designed so that the center distance between adjacent insertion grooves 3 is kept at more than 3mm, thereby ensuring that there is sufficient electrical clearance between the pins 7 installed at the bottom of the groove.
[0064] This application further proposes that the top of the power supply base is provided with a mounting plate 10, and the mounting plate 10 is provided with mounting holes on the left and right sides.
[0065] The process is designed to accommodate fasteners such as bolts and screws for mechanical fixation.
[0066] Specifically, the mounting plate 10 is integrated into the top plane of the power supply base, and the mounting holes symmetrically distributed on its left and right sides allow the base to be rigidly connected to the external device by fasteners; when the connector needs to be fixed to the scooter body, the bolt can pass through the mounting hole and cooperate with the corresponding threaded hole to form a fixing force perpendicular to the insertion direction, ensuring that the power supply base 100 is firmly installed on the scooter body.
[0067] This application further proposes a scooter charging device, including a charging connector. The charging connector includes a power-consuming base 100 and a power-supply base 200. The power-consuming base 100 has an open cavity 1 at one end. The power-supply base 200 is movably connected to the cavity 1. A partition plate 2 is provided at the bottom of the cavity 1, dividing the cavity 1 into several insertion slots 3. Pins 7 are inserted into the bottom of the insertion slots 3. One end of the power-supply base 200 has a partition groove 4 corresponding to the partition plate 2, so that the end of the power-supply base 200 forms several insertion parts 5. The insertion parts 5 are provided with connection terminals 6. The insertion parts 5 are inserted into the insertion slots 3 from the open end of the power-consuming base 100, and the pins 7 are inserted into the connection terminals 6.
[0068] Among them, the scooter charging equipment refers to the power transmission device designed specifically for scooters. Specifically, it can use a metal shell to enclose the charging connector to achieve protection. It realizes the physical connection and current transmission between the power supply end and the power consumption end through the charging connector. As the core component, the charging connector achieves precise alignment through the cooperation of the plug part 5 and the plug slot 3. The matching structure of the partition plate 2 and the partition slot 4 can limit the lateral displacement during the plugging process, thereby improving the plugging stability.
[0069] Specifically, when the power supply base 200 is inserted into the receiving cavity 1 of the power consumption base 100, the engagement of the partition groove 4 and the partition plate 2 allows the plug part 5 to accurately enter the corresponding plug groove 3. At this time, the connecting terminal 6 and the pin 7 form electrical contact. The pin 7 is fixedly installed at the bottom of the plug groove 3, and the plug part 5 is fixedly connected to the terminal 6 through the second mounting hole 51. The two are mechanically fixed through interference fit. The fit between the positioning cut surface and the positioning surface 101 can prevent rotational misalignment during the plugging process. The stepped hole structure restricts the axial displacement of the pin 7 or the connecting terminal 6 through the annular protrusion 701, thereby ensuring the reliability of the electrical connection.
[0070] Compared with existing technologies, traditional scooter charging devices rely on the clamping force of a single center pin and terminal to fix the plug, which is insufficient for insertion and extraction and is prone to loosening. In contrast, this solution uses a multi-point positioning structure of partition plate 2 and insertion groove 3 to disperse insertion stress and enhance insertion and extraction stability. In existing technologies, the gap between the terminal and the center pin is prone to widening due to vibration, while in this solution, the tight fit between the insertion part 5 and the insertion groove 3 can suppress displacement caused by vibration.
[0071] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
