Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically, to a vehicle charging dock. Background Technology

[0002] With the booming development of the new energy vehicle industry, vehicle charging equipment, as a key component for energy replenishment of new energy vehicles, is receiving increasing attention for its performance and reliability. As an important interface connecting the vehicle to an external power source, vehicle charging sockets not only need to have good electrical connection performance, but also need to possess waterproof, dustproof, and weather-resistant characteristics to ensure stable operation in various harsh environments, guaranteeing user safety and charging efficiency.

[0003] In related technologies, car chargers are often designed with a split structure, consisting of multiple independent components such as a base, a rear cover, and a sealing ring. During installation, the printed circuit board (PCB) must first be precisely assembled into the base. Then, the rear cover is placed on top of the base using screws, clips, or other fastening methods, and a sealing ring is installed between the base and the rear cover to form a sealed charging space. While this design meets the basic functional requirements of a charger to some extent, it has significant shortcomings: Firstly, the combination of multiple independent components increases the number of parts, raising production costs and increasing the complexity and error rate during assembly. Secondly, the split structure limits the installation space and ease of operation of the PCB, especially in the space-constrained environment of a car interior, where installation can become particularly cumbersome, impacting production efficiency. Furthermore, traditional chargers often rely on additional accessories such as sealing rings for waterproofing and dustproofing. The installation quality of these accessories directly affects the overall sealing effect of the charger, and they are prone to aging and detachment after long-term use, affecting the product's durability and safety.

[0008] Optionally, the inner peripheral wall of the mounting cavity is provided with a guide limiting slot extending along the insertion direction, and the side of the PCB board is embedded in the guide limiting slot.

[0009] Optionally, a waterproof cover is connected to the outer periphery of the insertion port, and hooks are provided on both sides of the waterproof cover. The base shell is provided with corresponding slots on both sides of the insertion port. When the waterproof cover is closed on the insertion port, the hooks and slots are engaged and fixed.

[0010] Optionally, the inner peripheral wall of the insertion port is connected to a first sealing element. When the waterproof cover is closed on the insertion port, the inner peripheral wall of the waterproof cover presses against the first sealing element to form a sealing fit.

[0011] Optionally, the upper end of the base housing is provided with an electrical connection port corresponding to the electrical connection part, and the electrical connection part is exposed to the electrical connection port.

[0012] Optionally, the terminal includes a signal terminal and a charging terminal; the mounting hole includes a first mounting hole for mounting the signal terminal and a second mounting hole for mounting the charging terminal, wherein the first mounting hole includes a first upper mounting hole and a first lower mounting hole that communicate with each other, and the second mounting hole includes a second upper mounting hole and a second lower mounting hole that communicate with each other; the signal terminal is inserted into the first lower mounting hole through the first upper mounting hole, and the charging terminal is inserted into the second lower mounting hole through the second upper mounting hole; the charging terminal is electrically connected to a charging cable, one end of which extends into the second upper mounting hole and is electrically connected to the charging terminal.

[0013] Optionally, both the first upper mounting hole and the second upper mounting hole penetrate the upper end of the base housing; the inner walls of both the first lower mounting hole and the second lower mounting hole are provided with radially extending limiting steps, and the bottom of the signal terminal and the bottom of the charging terminal respectively abut against the corresponding limiting steps.

[0014] Optionally, a second sealing element is provided in the first upper mounting hole for waterproofing the signal terminal; a third sealing element is provided in the second upper mounting hole for waterproofing the charging cable; and an end cap is connected to the upper end of the second upper mounting hole.

[0015] Optionally, the PCB board has a first connection hole corresponding to the signal terminal, one end of the signal terminal passes through the first connection hole and is inserted into the first lower mounting hole, and a spring contact electrically connected to the PCB board is provided at the first connection hole, and the signal terminal is electrically connected to the spring contact.

[0016] Optionally, the PCB board has a second connection hole corresponding to the charging terminal.

[0017] The beneficial effects of this vehicle charging socket are as follows: The vehicle charging socket mainly consists of an integrally molded hollow base shell, a PCB board, and multiple terminals. The base shell is the core load-bearing component. Its side wall has an insertion port, and an internal mounting cavity communicating with the insertion port is formed. Multiple mounting holes penetrating the mounting cavity are formed at the ends, with upper and lower ports located on the upper and lower end faces, respectively.

The portion of the terminal located within the mounting cavity forms an electrical connection with the PCB board, thereby achieving electrical conduction between the external power supply and the PCB board, providing an electrical connection channel for charging new energy vehicles.

[0018] Furthermore, compared to a split structure (composed of multiple independent components such as a base, rear cover, and sealing ring), the one-piece hollow base shell reduces the number of parts in the product. This reduction in parts directly lowers production costs, simplifies the assembly process, reduces complexity and error rates, and improves production efficiency. Moreover, the one-piece hollow base shell provides better installation space for the PCB board, solving the limitations imposed by split structures on PCB board installation space and ease of operation. In the space-constrained environment of a vehicle interior, the PCB board can be more easily inserted and fixed into the mounting cavity radially (perpendicular to the axial direction) through the insertion port, simplifying the installation process and contributing to improved production efficiency. Furthermore, the one-piece hollow base shell structure of this vehicle charging socket reduces sealing problems caused by the installation quality of additional accessories, improving the overall durability and safety of the product, ensuring stable operation in various harsh environments, and guaranteeing user safety and charging efficiency.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown in the figure, an embodiment of the present invention provides a vehicle charging base, including an integrally formed hollow base shell 1, an insertion port 11 on the side wall of the base shell 1, a mounting cavity 12 communicating with the insertion port 11 inside the base shell 1, and a plurality of mounting holes 13 through the mounting cavity 12 at the end of the base shell 1. Each mounting hole 13 has an upper port located above the mounting cavity 12 and a lower port located below the mounting cavity 12, which are arranged opposite to each other along the axial direction; a PCB board 2, which is used to be inserted radially through the insertion port 11 and fixed in the mounting cavity 12, one end of the PCB board 2 extends to the insertion port 11 and forms an electrical connection part 21 for connecting external devices; and a plurality of terminals 3, each terminal 3 passing through the upper port and lower port of the corresponding mounting hole 13 along the axial direction, and the portion of each terminal 3 located in the mounting cavity 12 is electrically connected to the PCB board 2.

[0029] Specifically, the one-piece hollow base shell 1 serves as the basic structure of the entire charging base. The insertion port 11 on its side wall provides a channel for the insertion of the PCB board 2, while the internal mounting cavity 12 provides space for the installation of the PCB board 2. Multiple mounting holes 13, penetrating the mounting cavity 12, are opened at the top of the base shell 1, providing a path for the installation and positioning of the terminals 3. During assembly, the PCB board 2 is first inserted longitudinally through the insertion port 11 and fixed within the mounting cavity 12. One end of the PCB board 2 extends to the insertion port 11, forming an electrical connection part 21 for connecting external devices, thus achieving electrical connection with external devices. Next, multiple terminals 3 are inserted from top to bottom through the upper ports of the corresponding mounting holes 13 and into the lower ports. The portion of the terminal 3 located within the mounting cavity 12 forms an electrical connection with the PCB board 2, thereby establishing an electrical path between the terminals 3 and the PCB board 2. This allows external power to transmit electrical energy through the terminals 3 and the PCB board 2, thereby charging new energy vehicles.

[0030] In this embodiment, a one-piece hollow base shell 1 is adopted, which greatly reduces the number of parts compared to the design of a split structure composed of multiple independent components such as the base, back cover, and sealing ring. The reduction in the number of parts directly lowers production costs, simplifies the assembly process, reduces complexity and error rates, and improves production efficiency. The one-piece base shell 1 provides a more reasonable installation space for the PCB board 2. In the space-constrained environment of a vehicle interior, the PCB board 2 is inserted longitudinally into and fixed within the mounting cavity 12 via the insertion port 11, making the installation process more convenient and avoiding the limitations imposed by the traditional split structure on the installation space and ease of operation of the PCB board 2, thus improving production efficiency. Furthermore, the one-piece base shell 1 has a more compact structure, reducing the problems associated with relying on additional accessories such as sealing rings for waterproofing and dustproofing in traditional structures. It avoids the problems of aging and detachment of sealing rings after long-term use, thereby improving the durability and safety of the product and ensuring that the vehicle charging dock can still work stably in various harsh environments, guaranteeing user safety and charging efficiency.

[0031] Optionally, such as Figure 3 As shown, the inner peripheral wall of the mounting cavity 12 is provided with a guide limiting slot 14 extending along the insertion direction, and the side of the PCB board 2 is embedded in the guide limiting slot 14.

[0032] Specifically, during the installation of the vehicle charging base, when the PCB board 2 is radially inserted into the mounting cavity 12 through the insertion port 11, the side of the PCB board 2 will be embedded in the guide limiting slot 14 extending along the insertion direction, since the inner peripheral wall of the mounting cavity 12 is provided with a guide limiting slot 14. The guide limiting slot 14 plays a role in guiding and restricting the movement of the PCB board 2. During the insertion of the PCB board 2, the slot provides a clear path for the PCB board 2 along the insertion direction, ensuring that the PCB board 2 can enter the mounting cavity 12 accurately and smoothly in the correct direction, and restricting the lateral and longitudinal displacement of the PCB board 2 in the mounting cavity 12, so that the PCB board 2 can be stably fixed in the predetermined position in the mounting cavity 12, thereby completing the installation of the PCB board 2.

[0033] In this optional embodiment, the guide limiting slot 14 provides precise guidance for the insertion of the PCB board 2, avoiding installation difficulties or failure to be installed in the correct position due to directional deviation during insertion. This greatly improves the accuracy of PCB board 2 installation, ensuring that the PCB board 2 can correctly mate with other components (such as terminals 3) within the mounting cavity 12, achieving reliable electrical connection. Furthermore, by embedding the side of the PCB board 2 within the guide limiting slot 14, it effectively limits the PCB board 2's movement and displacement within the mounting cavity 12, allowing the PCB board 2 to be stably fixed within the mounting cavity 12. This reduces potential problems such as loose electrical connections or poor contact due to PCB board 2 instability, improving the overall stability and reliability of the vehicle charging socket. The guide limiting slot 14 makes the installation process of the PCB board 2 simpler and faster. Operators do not need to perform complex positioning and adjustment operations; they only need to insert the PCB board 2 along the slot to complete the installation, reducing installation difficulty and improving production efficiency.

[0034] Optionally, such as Figure 1 , Figure 3 As shown, a waterproof cover 15 is connected to the outer periphery of the insertion port 11. Hooks 151 are provided on both sides of the waterproof cover 15. The base shell 1 is provided with corresponding slots 16 on both sides of the insertion port 11. When the waterproof cover 15 is closed on the insertion port 11, the hooks 151 and slots 16 are engaged and fixed.

[0035] Specifically, after the vehicle charging base completes the assembly of components such as the PCB board 2 and terminals 3, the waterproof cover 15 is placed over the insertion port 11. At this time, the hooks 151 on both sides of the waterproof cover 15 will contact the corresponding slots 16 on both sides of the base housing 1 at the insertion port 11. As the waterproof cover 15 continues to close, the hooks 151 will undergo a certain degree of elastic deformation due to the pressure from the edge of the slot 16. When the hooks 151 reach a specific position in the slot 16, the elasticity returns, and the hooks 151 and the slots 16 are engaged and fixed, thereby tightly fixing the waterproof cover 15 at the insertion port 11 and sealing the insertion port 11.

[0036] In this optional embodiment, the waterproof cover 15 seals the insertion port 11, effectively preventing external moisture, dust, and other impurities from entering the charging dock through the insertion port 11. This protects key components inside the charging dock, such as the PCB board 2 and terminals 3, from moisture and contamination, improving the waterproof capability of the vehicle charging dock in various harsh environments and ensuring its normal operation and safety. The snap-fit ​​fixing method between the hook 151 and the slot 16 ensures the waterproof cover 15 is stably secured to the insertion port 11, preventing it from easily falling off due to external vibrations or impacts, thus ensuring the durability and reliability of the waterproof effect. The snap-fit ​​structure between the hook 151 and the slot 16 makes the installation and removal of the waterproof cover 15 relatively simple. When maintenance, repair, or replacement of components is required inside the charging dock, the waterproof cover 15 can be easily removed by simply disengaging the hook 151 from the slot 16, facilitating related work and improving maintenance efficiency.

[0037] Optionally, such as Figure 3 As shown, the inner peripheral wall of the insertion port 11 is connected to a first sealing element 17. When the waterproof cover 15 is closed on the insertion port 11, the inner peripheral wall of the waterproof cover 15 presses against the first sealing element 17 to form a sealing fit.

[0038] Specifically, in the structure of the vehicle charging dock, a first sealing element 17 is pre-connected to the inner peripheral wall of the insertion port 11. When the waterproof cover 15 is closed on the insertion port 11, the waterproof cover 15 gradually approaches the insertion port 11, and its inner peripheral wall comes into contact with the first sealing element 17. As the waterproof cover 15 continues to close, the inner peripheral wall of the waterproof cover 15 applies pressure to the first sealing element 17, causing the first sealing element 17 to undergo elastic deformation. This allows the first sealing element 17 to tightly fill the gap between the inner peripheral wall of the waterproof cover 15 and the inner peripheral wall of the insertion port 11, forming a sealing fit and effectively preventing external moisture, dust, and other impurities from entering the charging dock through the insertion port 11.

[0039] In this optional embodiment, the sealing fit between the first sealing member 17 and the inner peripheral wall of the waterproof cover 15 further enhances the sealing effect at the insertion port 11, providing a more reliable waterproof and dustproof barrier than relying solely on the direct contact between the waterproof cover 15 and the insertion port 11. Even if there are minor installation errors or manufacturing tolerances between the waterproof cover 15 and the insertion port 11, the first sealing member 17 can compensate for these gaps through elastic deformation, ensuring that the inside of the charging dock is always in a dry and clean environment, greatly improving the adaptability and reliability of the vehicle charging dock in harsh environments. Good sealing performance can effectively prevent moisture and dust from corroding key components such as the PCB board 2 and terminals 3 inside the charging dock, reducing component damage and short circuits caused by moisture and pollution, thereby extending the overall service life of the vehicle charging dock and reducing product maintenance and replacement costs.

[0040] Optionally, such as Figure 1 As shown, the upper end of the base housing 1 is provided with an electrical connection port 18 corresponding to the electrical connection part 21, and the electrical connection part 21 is exposed to the electrical connection port 18.

[0041] Specifically, in the structure of the vehicle charging dock, an electrical connection port 18 is provided on the upper end of the base shell 1 corresponding to the electrical connection portion 21 formed on the PCB board 2. After the vehicle charging dock is installed, since the electrical connection portion 21 is exposed to the electrical connection port 18, the connecting parts of external devices can be directly electrically connected to the electrical connection portion 21 through the electrical connection port 18. After the connecting parts of the external devices are inserted into the electrical connection port 18, they make close contact with the electrical connection portion 21, thereby outputting the signals on the PCB board 2 to the outside.

[0042] In this optional embodiment, the electrical connection portion 21 is exposed at the electrical connection port 18, making the connection process between the external device and the vehicle charging dock simpler and more direct. Operators do not need to perform complex operations or additional structural adjustments; they can simply insert the charging plug of the external device into the electrical connection port 18 to achieve electrical connection, reducing operational difficulty and improving ease of use.

[0043] Optionally, such as Figure 1 , Figure 2 , Figure 3As shown, terminal 3 includes a signal terminal 31 and a charging terminal 32; mounting hole 13 includes a first mounting hole 131 for mounting the signal terminal 31 and a second mounting hole 132 for mounting the charging terminal 32, wherein the first mounting hole 131 includes a first upper mounting hole 1311 and a first lower mounting hole 1312 that are connected, and the second mounting hole 132 includes a second upper mounting hole 1321 and a second lower mounting hole 1322 that are connected; the signal terminal 31 is inserted into the first lower mounting hole 1312 through the first upper mounting hole 1311, and the charging terminal 32 is inserted into the second lower mounting hole 1322 through the second upper mounting hole 1321; the charging terminal 32 is electrically connected to a charging cable, one end of which extends into the second upper mounting hole 1321 and is electrically connected to the charging terminal 32.

[0044] Specifically, in the vehicle charging socket structure, terminal 3 is clearly divided into signal terminal 31 and charging terminal 32. The corresponding mounting holes 13 are also divided into a first mounting hole 131 for mounting signal terminal 31 and a second mounting hole 132 for mounting charging terminal 32. The first mounting hole 131 consists of a first upper mounting hole 1311 and a first lower mounting hole 1312, and the second mounting hole 132 consists of a second upper mounting hole 1321 and a second lower mounting hole 1322. During installation, signal terminal 31 is inserted through the first upper mounting hole 1311 and enters the first lower mounting hole 1312 along the connecting path of mounting hole 13, completing the installation of signal terminal 31; charging terminal 32 is inserted through the second upper mounting hole 1321 and enters the second lower mounting hole 1322, achieving the installation and positioning of charging terminal 32. Signal terminal 31 is typically used to transmit various control signals during the charging process, such as charging start signals and charging status feedback signals. Its structure is intricate to ensure accurate signal transmission. The signal terminal 31 is generally made of a metal material with good conductivity and a certain degree of elasticity, such as copper alloy, to ensure the stability and reliability of signal transmission. The charging terminal 32 includes a grounding terminal, a positive current terminal, and a negative current terminal. The grounding terminal provides grounding protection before, during, and after charging, while the positive and negative terminals provide the charging function. The charging terminal 32 is responsible for transmitting a large charging current, therefore it needs good conductivity and heat dissipation performance. Its structure is relatively large and thick to withstand the large current. The surface of the charging terminal 32 is usually specially treated, such as silver plating, to improve conductivity and corrosion resistance. The charging terminal 32 is electrically connected to a charging cable. After the charging terminal 32 is installed into the second lower mounting hole 1322, one end of the charging cable extends into the second upper mounting hole 1321 and is electrically connected to the charging terminal 32, thus establishing a power transmission channel between the charging cable and the charging terminal 32. This allows the power from the external power source to be transmitted to the charging terminal 32 via the charging cable, and then to the battery of the new energy vehicle via other electrical structures inside the charging socket.

[0045] In this optional embodiment, terminal 3 is divided into signal terminal 31 and charging terminal 32, and corresponding first mounting hole 131 and second mounting hole 132 are respectively provided, so that the signal transmission and charging functions are clearly distinguished in structure. Signal terminal 31 is dedicated to transmitting signals, and charging terminal 32 is dedicated to transmitting electrical energy, avoiding mutual interference between signal and electrical energy transmission and improving the stability and reliability of the vehicle charging socket. The first mounting hole 131 and the second mounting hole 132 are each divided into an upper mounting hole and a lower mounting hole with a connected structure, providing precise guidance and positioning for the installation of signal terminal 31 and charging terminal 32. Signal terminal 31 and charging terminal 32 are inserted along their respective mounting hole 13 paths, ensuring the accuracy and consistency of installation, reducing poor electrical connection or other problems caused by installation position deviation, and improving installation efficiency and quality. The charging cable extends into the second upper mounting hole 1321 and is electrically connected to the charging terminal 32, which not only facilitates the connection operation between the cable and the terminal, but also ensures the reliability of the connection. The second mounting hole 1321 provides some space and protection for the connection between the cable and the terminal, reducing the impact of the external environment on the connection part. It also helps to fix and organize the cable, making the internal structure of the entire charging dock more neat and orderly.

[0046] Optionally, such as Figure 2 As shown, the first upper mounting hole 1311 and the second upper mounting hole 1321 both penetrate the upper end of the base housing 1; the inner walls of the first lower mounting hole 1312 and the second lower mounting hole 1322 are provided with radially extending limiting steps 133, and the bottom of the signal terminal 31 and the bottom of the charging terminal 32 respectively abut against the corresponding limiting steps 133.

[0047] Specifically, both the first upper mounting hole 1311 and the second upper mounting hole 1321 penetrate the upper end of the base housing 1, providing an open and direct channel for the insertion of the signal terminal 31 and the charging terminal 32. During installation, the operator can easily and quickly insert the signal terminal 31 and the charging terminal 32 into the first upper mounting hole 1311 and the second upper mounting hole 1321 respectively from the upper end of the base housing 1. The inner walls of the first lower mounting hole 1312 and the second lower mounting hole 1322 are provided with radially extending limiting steps 133. When the signal terminal 31 is inserted into the first lower mounting hole 1312 through the first upper mounting hole 1311 and the charging terminal 32 is inserted into the second lower mounting hole 1322 through the second upper mounting hole 1321, as the terminals are inserted deeper, the bottom of the signal terminal 31 and the bottom of the charging terminal 32 will contact and abut against the corresponding limiting steps 133 respectively. The limiting step 133 plays a precise positioning role, restricting the terminal 3 from moving further downward, ensuring that the terminal 3 is installed in the appropriate position, and ensuring that the electrical connection and mechanical cooperation between the terminal 3 and other components inside the charging socket are in the best state.

[0048] In this optional embodiment, the first upper mounting hole 1311 and the second upper mounting hole 1321 penetrate the upper end of the base housing 1, allowing the insertion of the terminal 3 to be unobstructed by other structures. Operators can directly install it from above without complex operating steps or special tools, greatly improving installation efficiency and reducing installation difficulty and cost. The limiting step 133 accurately determines the installation positions of the signal terminal 31 and the charging terminal 32, avoiding problems such as poor electrical connection and loose mechanical fit caused by terminal installation position deviations. This precise positioning ensures a stable connection between the terminal and other internal components of the charging socket, improving the reliability and stability of the vehicle charging socket and reducing malfunctions and maintenance costs caused by installation problems. Through the penetration of the mounting hole 13 and the positioning of the limiting step 133, the entire terminal 3 installation structure is more compact and reasonable, making full use of the internal space of the base housing 1. This not only helps to reduce the size of the charging socket and improve its installation adaptability in the limited space inside the vehicle, but also reduces material usage and lowers production costs.

[0049] Optionally, such as Figure 3 As shown, a second sealing element 134 is provided in the first upper mounting hole 1311 for waterproofing the signal terminal 31; a third sealing element 135 is provided in the second upper mounting hole 1321 for waterproofing the charging cable; and an end cap 136 is connected to the upper end of the second upper mounting hole 1321.

[0050] Specifically, a second sealing element 134 is provided inside the first upper mounting hole 1311. When the signal terminal 31 is inserted into the first lower mounting hole 1312 from the first upper mounting hole 1311, the second sealing element 134 is installed inside the first upper mounting hole 1311, forming a sealing barrier. This sealing barrier can effectively prevent external moisture, dust, and other impurities from entering the interior of the first mounting hole 131, thereby protecting the signal terminal 31 from the influence of a humid environment and ensuring the stability and reliability of signal transmission. A third sealing element 135 is provided inside the second upper mounting hole 1321. After the charging cable is inserted into the second upper mounting hole 1321 and electrically connected to the charging terminal 32, it will tightly wrap the charging cable. In this way, the third sealing element 135 blocks the path for moisture to enter the charging socket from the gap between the second upper mounting hole 1321 and the charging cable, preventing moisture from damaging the charging cable and the connected charging terminal 32, and ensuring the normal operation of the charging function. The end cap 136 connected to the upper end of the second upper mounting hole 1321 can close the upper end of the second upper mounting hole 1321 after the charging cable is installed, thereby fixing the third sealing element 135, providing a certain pressure to the third sealing element 135, ensuring that the third sealing element 135 plays a sealing role, and providing support for the charging cable.

[0051] In this optional embodiment, by providing a second seal 134, a third seal 135, and an end cap 136, a multi-layered waterproof protection system is formed, greatly improving the waterproof capability of the vehicle charging dock at the signal terminal 31 and related parts of the charging cable. Even in humid or rainy environments, it can effectively prevent moisture from entering the charging dock, reducing the risk of electrical faults and short circuits caused by moisture, and extending the service life of the charging dock. The end cap 136 not only serves a waterproof function but also provides a certain degree of physical protection for the second upper mounting hole 1321 and the charging cable and charging terminal 32 inside, preventing damage to internal components from external object collisions or scratches, thus improving the overall structural strength and safety of the charging dock.

[0052] Optionally, such as Figure 4 As shown, the PCB board 2 has a first connection hole 22 corresponding to the signal terminal 31. One end of the signal terminal 31 passes through the first connection hole 22 and is inserted into the first lower mounting hole 1312. The first connection hole 22 is provided with a spring piece 24 that is electrically connected to the PCB board 2. The signal terminal 31 is electrically connected to the spring piece 24.

[0053] Specifically, one end of the signal terminal 31 passes through the corresponding first connection hole 22 on the PCB board 2, and then continues to be inserted into the first lower mounting hole 1312. The first connection hole 22 serves to guide and position the installation of the signal terminal 31, ensuring that the signal terminal 31 can accurately reach the designated position and make correct electrical and mechanical connections with the PCB board 2 and other components. A spring contact 24 electrically connected to the PCB board 2 is provided at the first connection hole 22. When the signal terminal 31 passes through the first connection hole 22, the spring contact 24, due to its own elasticity, will make close contact with the signal terminal 31, thereby realizing the electrical connection between the signal terminal 31 and the PCB board 2. The contact method of the spring contact 24 can ensure a good electrical connection while adapting to the slight displacement or vibration that may occur in the signal terminal 31 during installation and use, ensuring the stability and reliability of the electrical connection.

[0054] In this optional embodiment, by providing a first connection hole 22 on the PCB board 2, the signal terminal 31 can be directly installed through the hole, eliminating the need for complex positioning and fixing steps. This greatly simplifies the installation process, improves installation efficiency, and reduces production costs and manual operation difficulty. The tight contact electrical connection between the spring contact 24 and the signal terminal 31 effectively reduces signal transmission problems caused by poor contact, such as signal interference, loss, or attenuation. The elasticity of the spring contact 24 ensures that the signal terminal 31 and the PCB board 2 maintain a good electrical connection under different environmental conditions (such as temperature changes, vibration, etc.), improving the stability and reliability of the entire vehicle charging dock system.

[0055] Optionally, such as Figure 4As shown, the PCB board 2 has a second connection hole 23 corresponding to the charging terminal 32. One end of the charging terminal 32 passes through the second connection hole 23 and is inserted into the second lower mounting hole 1322. The second connection hole 23 is provided with a connecting block 25 that is electrically connected to the PCB board 2. The charging terminal 32 is electrically connected to the connecting block 25.

[0056] Specifically, one end of the charging terminal 32 passes through the corresponding second connection hole 23 on the PCB board 2 and is then inserted into the second lower mounting hole 1322. The second connection hole 23 serves as a guide and positioning point, ensuring that the charging terminal 32 accurately reaches the designated position and achieves correct electrical and mechanical connection with the PCB board 2 and other components, thus ensuring the normal operation of the charging function. A connecting block 25 electrically connected to the PCB board 2 is provided at the second connection hole 23. When the charging terminal 32 passes through the second connection hole 23, the connecting block 25 makes close contact with the charging terminal 32, thereby establishing an electrical connection between the charging terminal 32 and the PCB board 2. This contact method can accommodate minor displacements or vibrations that may occur during the installation and use of the charging terminal 32, maintaining the stability and reliability of the electrical connection. In this embodiment, both the positive and negative terminals are electrically connected to the PCB board 2 through thermally conductive silicone. The thermally conductive silicone receives the thermal signal from the charging terminal 32 and transmits it to the PCB board 2 through a thermistor. The grounding terminal is electrically connected to the PCB board 2 through the elastic connecting block 25.

[0057] In this optional embodiment, a second connection hole 23 is provided on the PCB board 2, allowing the charging terminal 32 to be directly installed through this hole. This eliminates the need for complex positioning and fixing steps, simplifying the installation process, improving installation efficiency, and reducing production costs and manual operation difficulty. The tight contact electrical connection between the connecting block 25 and the charging terminal 32 effectively reduces charging problems caused by poor contact, such as charging interruptions and unstable current. The elasticity or good contact characteristics of the connecting block 25 ensure that the charging terminal 32 and the PCB board 2 maintain a good electrical connection under different environmental conditions (such as temperature changes, vibration, etc.), improving the stability and reliability of the vehicle charging dock charging system.
