Description

Technical Field

[0001] This utility model relates to a vehicle charger, specifically to a conductive spring positioning and mounting structure for a vehicle charger. Background Technology

[0002] With the widespread use of electronic devices, on-board chargers have become an indispensable part of vehicles. Traditional on-board chargers typically use a single-layer circuit board or a separate negative electrode conductive structure, which, while achieving conductive connection, also needs to meet good mechanical strength and assembly reliability. However, in existing technologies, the negative electrode conductive spring is mostly a separate component, fixed to the circuit board by welding or clamping. This method has the following technical drawbacks:

[0003] The negative conductive contact of the negative conductive spring usually needs to be precisely positioned and then fixed by left and right welding or clamping, which increases the assembly difficulty and reduces production efficiency.

[0004] The soldered negative conductive spring needs to be removed during the repair process, which is not only time-consuming and labor-intensive, but also easily damages the circuit board and increases the repair cost.

[0005] Because the negative electrode conductive contact is made by single-point welding or clamping, the connection strength is relatively weak. It is easy to loosen or make poor contact due to vibration or long-term use, which affects the conductivity.

[0006] Traditional negative electrode conductive spring designs require adjustments for different circuit board sizes and wiring, lacking versatility and limiting the product's compatibility with different vehicle chargers. Utility Model Content

[0007] To address the aforementioned issues, this invention provides a conductive spring positioning and mounting structure for a vehicle charger, which integrates the negative conductive spring with a dual circuit board, simplifying the assembly process while improving conductivity reliability and structural stability to meet the technical requirements of miniaturization and high efficiency in vehicle chargers.

[0008] This utility model is achieved through the following technical solution: a conductive spring positioning and mounting structure for a vehicle charger, comprising:

[0009] A housing, wherein a positive electrical contact is provided at one end of the housing, and a cavity for mounting the motherboard assembly is formed inside the housing;

[0010] A dual circuit board is installed inside the housing, with a central positioning element positioned between the dual circuit boards and installed on either the first or the second circuit board.

[0011] A negative conductive spring is installed in the middle of the dual circuit boards and located on the lower end face of the central positioning member, making electrical contact and conductive connection with it.

[0012] A voltage-conducting tight contact is located on the lower end face of the negative conductive spring and is mounted on the first circuit board or the second circuit board. It is electrically connected to the dual circuit boards. The voltage-conducting tight contact is used to press the negative conductive spring against the lower end face of the central positioning member, and conduct electricity through the voltage-conducting tight contact to connect the negative conductive spring of the central positioning member or the dual circuit board.

[0013] As a preferred technical solution, the dual circuit board includes a first circuit board and a second circuit board, which are arranged in layers, and the sides of the first circuit board and the second circuit board away from the conductive contact are electrically connected by a conductive connecting piece.

[0014] As a preferred technical solution, the negative conductive spring includes a negative conductive contact, a spring connecting section, and a connecting section. The spring connecting section is located on both sides of the connecting section and is connected through the connecting section. The negative conductive contact is disposed at one end of the spring connecting piece, and the other end of the spring connecting piece is connected to the connecting section. The conductive clamping element is located on the lower end face of the connecting section.

[0015] As a preferred technical solution, the conductive clamping component includes a conductive connection part and an elastic clamping part. The elastic clamping part is used to elastically clamp the negative electrode conductive spring sheet onto the central positioning component, and the conductive connection part is conductively connected to the second circuit board.

[0016] As a preferred technical solution, the first circuit board is provided with at least one first charging interface, and the second circuit board is provided with at least one second charging interface, both of which are exposed on the charging end face of the housing.

[0017] As a preferred technical solution, a groove is also provided on the charging end face, and a pull ring is hinged in the groove to facilitate removal from the cigarette lighter.

[0018] As a preferred technical solution, the negative conductive contact and the positive electrical contact are respectively exposed on the outside of the housing.

[0019] The beneficial effects of this utility model are: First, the negative electrode conductive spring is designed as an integrated unit, which eliminates the need for additional welding or complex installation procedures. It can be directly clipped between the two circuit boards, which significantly improves assembly efficiency and reduces production costs.

[0020] Second, the elastic clamping action of the conductive clamping component not only enhances the fixing stability of the negative conductive spring, but also ensures its reliable conductive connection with the dual circuit boards, effectively avoiding poor contact problems caused by vibration or long-term use.

[0021] Third, the design of this utility model simplifies the repair process. The negative electrode conductive spring can be easily disassembled and reinstalled, improving the maintainability of the product. At the same time, the first circuit board and the second circuit board are connected by a conductive connecting piece, supporting a multi-interface charging design and realizing a reasonable layout and efficient utilization of the charging interface.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0031] like Figures 1-4As shown, this utility model relates to a conductive spring positioning and mounting structure for a vehicle charger. Through optimized design, it improves assembly efficiency, ease of repair, and enhanced conductivity reliability. The following detailed description of the embodiments of this utility model, in conjunction with the specific structure, provides a comprehensive overview.

[0032] The vehicle charger includes a housing 1, with a positive electrical contact 3 at one end for connecting to an external power source to achieve positive conductivity. The housing 1 contains a cavity for mounting the motherboard assembly and other electronic components. The cavity design optimizes internal space, allowing for compact installation of components, reducing size while ensuring ease of assembly.

[0033] The dual circuit boards are installed inside the housing 1 and arranged in upper and lower layers. The dual circuit boards include a first circuit board 10 and a second circuit board 11. The two circuit boards are positioned by a central positioning component 6 to ensure the accuracy and stability of their position during assembly. The central positioning component 6 not only fixes the dual circuit boards but also provides mounting support for the negative electrode conductive spring 100, enabling the entire structure to maintain stability while possessing efficient conductive connection performance.

[0034] The negative conductive spring 100 is disposed between the two circuit boards and located on the lower end face of the central positioning member 6. Its structure is designed as an integrated unit, including a negative conductive contact 2, a spring connecting section 15, and a connecting section 12. The spring connecting sections 15 are distributed on both sides of the connecting section 12 and are connected to form a whole through the connecting section 12. The negative conductive contact 2 is located at one end of the spring connecting section 15 and is used to contact an external negative electrode to complete the negative conductive function. The other end of the spring connecting section 15 is connected through the connecting section 12, and the lower end face of the connecting section 12 contacts the conductive contact member 200. Through this structural design, the negative conductive spring 100 can provide good elasticity while achieving the conductive function, enhancing its installation stability and reliability.

[0035] The conductive contact 200 is located on the lower end face of the negative conductive spring 100, and is responsible for pressing the negative conductive spring 100 against the lower end face of the center positioning member 6. The conductive contact 200 includes a conductive connection portion 13 and an elastic pressing portion 14, wherein the elastic pressing portion 14 provides sufficient elastic pressure to ensure that the negative conductive spring 100 is securely positioned and reliably contacts the circuit board. The conductive connection portion 13 is conductively connected to the second circuit board 11 to ensure the integrity and stability of the circuit.

[0036] To achieve conductive connection between the two circuit boards, the sides of the first circuit board 10 and the second circuit board 11 away from the conductive contact 200 are connected by a conductive connecting piece 16, which not only simplifies the complexity of the circuit connection, but also provides support for multi-interface charging.

[0037] Specifically, the first circuit board 10 is provided with at least one first charging port 5, and the second circuit board 11 is provided with at least one second charging port 8. Both charging ports are exposed on the charging end face 7 of the housing 1 for direct use by the user. This layout makes full use of the space of the two circuit boards, providing users with more charging options.

[0038] To enhance the user experience, a groove 9 is provided on the charging end face 7 of the housing 1, and a pull ring 4 is hinged within the groove 9. The pull ring 4 is designed to facilitate the user's lifting operation when using or moving the car charger, increasing the product's user-friendly design.

[0039] Furthermore, to ensure reliable conductive connection, both the negative conductive contact 2 and the positive electrical contact 3 are exposed outside the housing 1 to ensure good contact with external devices or power sources. This invention designs the negative conductive spring 100 as a single unit, eliminating the need for traditional welding or complex installation processes, and directly mounting it between the two circuit boards.

[0040] Through the elastic clamping action of the conductive contact 200, the negative conductive spring 100 can be firmly positioned and reliably connected to the upper and lower circuit boards, thereby significantly improving assembly efficiency and conductivity. Furthermore, this structural design makes rework more convenient, as the negative conductive spring 100 can be easily disassembled and reinstalled, enhancing product maintainability.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
