Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and more specifically, to a PCB board for a vehicle charging dock and a vehicle charging dock. Background Technology

[0002] As a means of transportation employing new power technologies, new energy vehicles require efficient and reliable charging solutions for their electric drive systems. Currently, common vehicle charging sockets on the market mainly adopt two structural forms: one is a design with an internal lead frame, achieving electrical connection through multiple lead terminals on the frame; the other uses a PCB board instead of a lead frame, directly soldering the terminals into the positioning holes on the PCB board. The former suffers from complex lead terminal processing and high production costs; while the latter, although reducing material costs, has significant technical drawbacks in practical use. Specifically, the terminals require multiple solder points for fixation during installation, which is not only cumbersome but also difficult to disassemble for later maintenance. Utility Model Content

[0003] The problem solved by this invention is to simplify the terminal installation process and improve the stability of terminal clamping.

[0004] To address the aforementioned problems, this utility model provides a PCB board for a car charging dock and a car charging dock.

[0005] In a first aspect, this utility model provides a PCB board for a vehicle charging dock, including a board body with multiple positioning holes for connecting terminals; each positioning hole is correspondingly provided with a spring sheet structure; the spring sheet structure includes a welding section, a connecting section, and a bonding section; the welding section is welded into a pre-set welding hole in the board body; the bonding section is connected to the welding section through the connecting section, and the bonding section is bonded to the hole wall of the positioning hole; both ends of the bonding section are connected to clamping sections; the clamping sections are used to clamp the terminals.

[0006] This invention relates to a PCB board for automotive charging sockets. When a terminal is inserted into a positioning hole, the clamping section expands outward under pressure; the welding section is fixed within the welding hole on the board, preventing overall displacement of the spring structure; the fitting section is tightly attached to the inner wall of the positioning hole, limiting the radial movement range of the spring structure; after the terminal is fully inserted, the clamping section clamps the terminal surface using elastic restoring force. The elasticity of the connecting section allows the clamping section to move during loading and unloading, while the welding section remains fixed. This allows the terminal to be fixed with only a single-point welding, with the remaining connections maintained by elastic clamping. By replacing most welding connections with elastic clamping, the terminal fixing method is changed from multi-point welding to single-point welding combined with elastic clamping, simplifying the assembly process. The reusable nature of the clamping section reduces maintenance costs. The segmented structure of the spring structure ensures reliable electrical connections while enabling rapid loading and unloading of the terminals.

[0007] Optionally, the clamping section includes an elastic clamping part and an elastic reset part; the two ends of the elastic clamping part are respectively connected to one end of the elastic reset part and the end of the fitting section; a gap is left between the elastic clamping part and the hole wall of the positioning hole; the end of the elastic reset part away from the fitting section is in contact with the hole wall of the positioning hole.

[0008] Optionally, a groove is provided in the positioning hole; the end of the elastic reset part away from the fitting section is located in the groove and contacts the bottom of the groove.

[0009] Optionally, the elastic clamping part and the elastic reset part are integrally molded parts.

[0010] Optionally, the surface of the mating section opposite to the mating side of the positioning hole is provided with multiple protrusions at intervals.

[0011] Optionally, the connecting section is an elastic structure; when the fitting section is in contact with the inner wall of the positioning hole, the elastic connector is in a stretched state.

[0012] Optionally, guide sections are provided at the end of the fitting section away from the connecting section and at both opposite ends of the clamping section; the guide sections are arranged at an angle away from the positioning hole.

[0013] Optionally, the width of the guide segment increases in the direction from one end near the mating segment to the other.

[0014] Optionally, the welding section, connecting section, bonding section, and clamping section are integrally formed parts.

[0015] Secondly, this utility model provides a vehicle charging dock, including a PCB board for the vehicle charging dock. Attached Figure Description

[0025] like Figure 1-4 As shown in the figure, the PCB board for a vehicle charging dock provided by this utility model includes a board body 1. The board body 1 has a plurality of positioning holes 101 for connecting terminals. Each positioning hole 101 is provided with a corresponding spring sheet structure 2. The spring sheet structure 2 includes a welding section 201, a connecting section 202 and a fitting section 204. The welding section 201 is welded into the pre-set welding hole 102 in the board body 1. The fitting section 204 is connected to the welding section 201 through the connecting section 202 and fits against the hole wall of the positioning hole 101. Both ends of the fitting section 204 are connected to clamping sections. The clamping sections are used to clamp the terminals.

[0026] The spring structure 2 refers to an elastic element made of conductive material, which can be achieved by stamping a thin copper alloy sheet, providing clamping force through elastic deformation. The soldering section 201 is the part fixed to the PCB board, which can be achieved using a rectangular or circular solder pad structure, ensuring electrical conductivity and mechanical fixation between the spring structure 2 and the board body 1. The connecting section 202 is the transition section connecting the soldering section 201 and the bonding section 204, which can be achieved using a bending structure, allowing the bonding section 204 to displace under force. The bonding section 204 is the part that contacts the inner wall of the positioning hole 101, which can be achieved using an arc-shaped plate structure, maintaining the relative position of the spring structure 2 within the positioning hole 101. The clamping sections are located at opposite ends of the bonding section 204, which can be the two ends of the arc-shaped plate in the bending direction. The clamping sections are the parts that directly contact the terminals, which can be achieved using an inwardly bent cantilever structure, generating continuous clamping force through elastic deformation.

[0027] Specifically, when the terminal is inserted into the positioning hole 101, the clamping section is compressed and expands outward, at which time the connecting section 202 undergoes elastic deformation to store potential energy. The welding section 201 is fixed inside the welding hole 102 of the plate 1, preventing the overall displacement of the spring structure 2. The fitting section 204 is tightly attached to the inner wall of the positioning hole 101, limiting the radial movement range of the spring structure 2. After the terminal is fully inserted, the clamping section clamps the terminal surface by relying on elastic restoring force. The elasticity of the connecting section 202 allows the clamping section to move during loading and unloading, while the welding section 201 remains fixed. Thus, the terminal only needs to be fixed and electrically connected by single-point welding, while the remaining connections are maintained by elastic clamping. This embodiment replaces most of the welding connections with elastic clamping. In the prior art, terminal disassembly requires destruction of the solder joint, while in this embodiment, the clamping section can elastically reset, allowing non-destructive disassembly. In addition, in this embodiment, the segmented design of the spring structure 2 allows the welding section 201 to only perform the fixing function, and the clamping force is generated by the elastic deformation of the clamping section. This embodiment changes the terminal fixing method from multi-point welding to single-point welding combined with elastic clamping, simplifying the assembly process. The reusable clamping section reduces maintenance costs, and the elastic design of the connecting section 202 compensates for manufacturing tolerances, improving assembly error tolerance. The segmented structure of the spring clip structure 2 ensures electrical connection reliability while enabling quick terminal installation and removal.

[0028] Optionally, the clamping section includes an elastic clamping part 203 and an elastic reset part 207; the two ends of the elastic clamping part 203 are respectively connected to one end of the elastic reset part 207 and the end of the fitting section 204; a gap is left between the elastic clamping part 203 and the hole wall of the positioning hole 101; the end of the elastic reset part 207 away from the fitting section 204 contacts the hole wall of the positioning hole 101.

[0029] The elastic clamping part 203 refers to a metal sheet structure with bending elasticity, which can be made by stamping copper alloy. It is used to generate elastic deformation to provide clamping force when the terminal is inserted. The elastic reset part 207 refers to an elastic support component connected to the elastic clamping part 203. It can be integrally formed from the same material as the elastic clamping part 203. It is used to form a lever fulcrum during clamping and to provide a reset force for the elastic clamping part 203. The gap refers to the space between the elastic clamping part 203 and the inner wall of the positioning hole 101. It can be achieved by adjusting the curvature of the elastic clamping part 203. It is used to provide displacement space for the deformation of the elastic clamping part 203 and avoid rigid friction with the hole wall. The hole wall contact of the positioning hole 101 refers to the point contact or line contact between the end of the elastic reset part 207 and the hole wall. It can be achieved by setting limiting protrusions on the hole wall. It is used to form a stable lever fulcrum and store elastic potential energy during clamping.

[0030] Specifically, when the terminal is inserted into the positioning hole 101, the sidewall of the terminal pushes the elastic clamping part 203 to deflect towards the hole wall. At this time, the elastic clamping part 203 undergoes lever deformation with the contact point between the elastic reset part 207 and the hole wall as the fulcrum, and the gap provides displacement space for the deformation. When the elastic reset part 207 is compressed, it generates a reverse force, causing the elastic clamping part 203 to form an elastic clamping on the terminal. When the terminal is pulled out, the elastic reset part 207 releases the stored elastic potential energy, pushing the elastic clamping part 203 back to its initial position, and the gap returns to its original width, achieving interference-free reset. This embodiment, through the linkage design of the elastic clamping part 203 and the elastic reset part 207, forms a double elastic support structure during the clamping process. The elastic reset part 207 not only serves as a deformation fulcrum but also supplements the clamping force through its own deformation, so that the clamping stability is not affected by single-point elastic fatigue. In addition, the gap setting changes the clamping process from sliding friction to clearance fit, reducing contact wear. It achieves dynamic balance of clamping force during terminal insertion and removal, which can enhance clamping stability during insertion through the double elastic structure and achieve rapid reset through the energy release of the elastic reset part 207 during removal.

[0031] Optionally, a groove 103 is provided in the positioning hole 101; the end of the elastic reset part 207 away from the fitting section 204 is located in the groove 103 and is in contact with the bottom of the groove 103.

[0032] The groove 103 refers to a recessed structure provided on the inner wall of the positioning hole 101. Specifically, the groove 103 can be formed on the PCB board 1 by machining or stamping. The bottom of the groove 103 is configured to provide a support surface to limit the offset of the elastic reset part 207 along the direction perpendicular to the terminal insertion and removal. The contact between the elastic reset part 207 and the bottom of the groove 103 means that the end of the reset piece forms a stable support with the bottom of the groove 103 through planar contact or curved contact. Specifically, the depth of the groove 103 can be adjusted to put the reset piece in a pre-compression state, thereby maintaining contact stability during clamping.

[0033] Specifically, the sidewall of the groove 103 provides lateral constraint to the elastic reset part 207, preventing lateral displacement during terminal insertion and removal. When the elastic clamping part 203 is subjected to terminal insertion pressure, the elastic reset part 207 undergoes axial elastic deformation along the bottom of the groove 103, avoiding stress concentration caused by suspension. The contact area between the bottom of the groove 103 and the end of the reset piece is set to be greater than the thickness of the reset piece, thereby dispersing stress and reducing material fatigue during repeated deformation. The groove 103 structure physically limits the reset piece to deform only in a preset direction, avoiding clamping force attenuation due to offset. The bottom support surface of the groove 103 replaces the traditional point contact method, making the stress distribution of the reset piece more uniform. This effectively prevents lateral displacement or detachment of the elastic reset part 207 during repeated clamping, ensuring that the clamping section is always within the preset deformation range. The groove 103 structure improves the positional stability of the reset piece through mechanical limiting, avoiding stress concentration and fracture caused by suspension deformation. The increased contact area significantly extends the service life of the reset piece under frequent deformation conditions.

[0034] Optionally, the elastic clamping part 203 and the elastic reset part 207 are integrally molded parts.

[0035] The integrally formed part refers to a continuous, seamless metal structure formed through a single processing step. Specifically, it can be achieved using stamping or precision casting processes, ensuring that the elastic clamping part 203 and the elastic reset part 207 form a continuous whole for mechanical transmission. The elastic clamping part 203 is a thin-walled structure that directly contacts the terminal surface and applies clamping force. The required elastic deformation capability can be achieved by adjusting the material thickness and bending angle. The elastic reset part 207 is an extension that contacts the inner wall of the positioning hole 101 and provides reset support for the elastic clamping part 203. Specifically, it can employ an arc-shaped or wave-shaped structure to achieve multi-directional elastic deformation. This embodiment simplifies the processing steps of the integral clamping section structure, reduces the number of parts and assembly errors, effectively improves the response speed and reset accuracy of the terminal clamping action, and avoids clamping loosening due to local connection failure through continuous mechanical transmission.

[0036] Optionally, a plurality of protrusions 205 are provided at intervals on the side surface of the mating section 204 that is opposite to the mating side of the positioning hole 101.

[0037] The protrusion 205 refers to a localized raised structure extending from the inner wall of the mating section 204 towards the center of the positioning hole 101. Specifically, it can be implemented using hemispherical protrusions or strip-shaped protrusions, and its surface contour is smoothed to reduce surface damage to the terminal. The interval arrangement refers to the non-continuous distribution of multiple protrusions 205 along the circumferential or axial direction of the inner wall of the mating section 204. Specifically, it can be implemented using uniform or staggered intervals, and its distribution density can be adjusted according to the terminal diameter and clamping force requirements.

[0038] Specifically, when the terminal is inserted into the positioning hole 101, the protrusion 205 contacts the outer surface of the terminal. Under the elastic action of the clamping section, the protrusion 205 undergoes local deformation and forms multiple independent contact points. Due to the spaced distribution of the protrusions 205, the contact area between the terminal and the spring structure 2 is decomposed into multiple discrete points, each of which independently generates a clamping effect under the elastic clamping force. This design concentrates the frictional resistance experienced by the terminal during insertion at the tip of the protrusion 205, while the gap between adjacent protrusions 205 provides space for uneven areas on the terminal surface. Through the spaced arrangement of the protrusions 205, while maintaining the clamping force, the contact pressure is distributed to multiple independent points, avoiding the problem of incomplete connection that may exist in planar contact, and improving the adaptability to terminal size fluctuations through discrete contact points. This effectively improves the contact stability between the spring structure 2 and the terminal, reduces the risk of increased contact resistance due to surface contamination or assembly deviation, and enhances the clamping compatibility for terminals of different specifications through the elastic synergistic effect of discrete contact points.

[0039] Optionally, the connecting section 202 is an elastic structure; when the fitting section 204 fits against the inner wall of the positioning hole 101, the elastic connector is in a stretched state.

[0040] Among them, elastic connectors refer to mechanical connection components with elastic deformation capabilities. Specifically, they can be made of elastic metal sheets or spring steel materials, and can generate a rebound force to restore their original shape after being stretched by external force. The tensile state refers to the working state in which the elastic connector is deformed when axial tensile force is applied during the assembly process. The deformation range can be the amount of elastic deformation within the yield strength range of the material.

[0041] Specifically, the elastic connector's initial free state length is less than its effective length after assembly. When the mating section 204 is pressed against the inner wall of the positioning hole 101, the elastic connector is forcibly stretched to a predetermined length, at which point elastic stress is generated within the material. This stress causes the elastic connector to tend to return to its initial length, thereby applying continuous pressure to the mating section 204 and forcing it to maintain tight contact with the inner wall of the positioning hole 101. During terminal insertion, when the clamping section is displaced by external force, the elastic connector's tensile deformation can be adjusted accordingly, offsetting the positional change caused by the displacement through stress release or increase. When the terminal is pulled out, the elastic connector's rebound force drives the clamping section to automatically return to its initial clamping position. By utilizing the pre-stretched state of the elastic connector, the mechanical stress generated during assembly is converted into a continuous clamping force on the contact surface. Simultaneously, the elastic deformation characteristics provide adaptive adjustment space for the clamping section, solving the defect that rigid connection structures cannot dynamically compensate for displacement. This achieves constant pressure contact between the spring structure 2 and the inner wall of the positioning hole 101, eliminating the phenomenon of increased contact resistance caused by assembly gaps. At the same time, it enables the clamping section to have an automatic reset function, eliminating the need for manual adjustment of the clamping component position during terminal insertion and removal, thus significantly improving connection stability and operational convenience.

[0042] Optionally, guide sections 206 are provided at one end of the fitting section 204 away from the connecting section 202 and at both opposite ends of the clamping section; the guide sections 206 are arranged at an angle away from the positioning hole 101.

[0043] The guide section 206 refers to the inclined guide structure located at the edge of the spring structure 2. Specifically, it can be formed by stamping and bending a metal sheet, with the bending angle controlled at approximately 45°. This inclined structure can generate outward elastic deformation when the terminal is inserted, thereby reducing contact resistance. The inclined arrangement away from the positioning hole 101 means that the outer end of the guide section 206 extends inclined outward from the positioning hole 101, and its inclination angle matches the insertion path of the terminal, allowing the end profile of the terminal to slide into the positioning hole 101 along the inclined surface of the guide section 206.

[0044] Specifically, when the terminal is inserted into the positioning hole 101, its end edge first contacts the inclined surfaces of the upper and lower guide sections 206. Under continuous insertion pressure, the guide sections 206 elastically expand outward, gradually increasing the opening gap of the clamping section. Because the upper and lower guide sections 206 are symmetrically distributed, the expansion force on the terminal is evenly distributed on both sides, avoiding skewness caused by unilateral force. After the terminal is fully inserted, the clamping section returns to its initial position under the action of elastic restoring force, achieving stable clamping of the terminal. During disassembly, as the terminal moves outward, it pushes the guide sections 206 to tilt in the opposite direction. The inclined surfaces of the guide sections 206 generate a guiding effect opposite to the deformation direction of the clamping section, assisting in the elastic restoring of the clamping section and preventing jamming caused by excessive deformation. This effectively reduces the frictional resistance of the terminal during installation and disassembly, avoids clamping misalignment due to skewness, and ensures terminal alignment through the bidirectional guiding structure, improving the stability of the electrical connection. During disassembly, the reverse force of the inclined surface of the guide section 206 can assist the clamping section to quickly reset, preventing disassembly difficulties caused by plastic deformation of the clamping section.

[0045] Optionally, the width of the guide segment 206 increases in the direction from one end near the mating segment 204 to the other end.

[0046] The guide section 206 refers to the guide structure located on the upper and lower sides of the mating section 204 and the clamping section. Specifically, it can be implemented using a metal sheet stamped into an inclined, extended plate-like structure. The guide section 206 is inclined away from the positioning hole 101, and its function is to provide a guiding surface for initial contact during terminal insertion. The gradually increasing width refers to the lateral dimension of the guide section 206 gradually expanding from the end closer to the mating section 204 to the end farther away from the mating section 204. This can be achieved by stamping a trapezoidal or triangular profile sheet metal. The width variation gives the initial contact area of ​​the guide section 206 a larger lateral dimension, while the lateral dimension of the extended area gradually increases, thus forming a gradually expanding guide trajectory during insertion.

[0047] Specifically, when the terminal is inserted into the positioning hole 101, the gradually expanding width design of the guide section 206 makes the gap between adjacent guide sections 206 relatively small, avoiding terminal misalignment or jamming between adjacent guide sections 206 due to excessive gap. During the terminal insertion process, the gradually expanding guide trajectory restricts the terminal's travel path, preventing mechanical interference or jamming between the terminal and the guide section 206 due to excessive gap, ultimately achieving fast, accurate, and stable terminal installation operation.

[0048] Optionally, the welding section 201, the connecting section 202, the bonding section 204, and the clamping section are configured as an integrally formed part.

[0049] The integrally formed part refers to the integral structure processed from different functional sections through stamping or casting processes. Specifically, continuous stamping and bending processes can be used to achieve seamless joints between the functional sections. The welding section 201 refers to the area that forms a fixed connection with the welding hole 102 of the plate 1. This can be achieved through surface tin plating to enhance the bonding strength with the solder. The connecting section 202 refers to the transition area connecting the welding section 201 and the mating section 204. This can be achieved using an arc-shaped or corrugated structure to provide space for elastic deformation. The mating section 204 refers to the area that contacts the wall of the positioning hole 101. This can be achieved using a planar or arc-shaped structure to ensure uniform contact pressure distribution. The clamping section refers to the area that forms a clamping force on the terminal. This can be achieved using a V-shaped or U-shaped opening structure to form a bidirectional elastic constraint.

[0050] Specifically, a continuous stress transmission path is formed among the functional segments through a one-piece molding. When the terminal is inserted into the positioning hole 101, the clamping segment deforms under external force. This deformation is transmitted to the connecting segment 202 through the fitting segment 204. The connecting segment 202 evenly distributes the elastic potential energy to the welding segment 201, preventing local stress concentration that could lead to structural fracture. During terminal removal, each functional segment recovers its initial shape based on the material's own elasticity, without the need for additional reset components. Since there are no assembly gaps between the segments, misalignment or slippage does not occur during deformation, thus maintaining the stability of the clamping force.

[0051] In some specific embodiments, the stamped metal sheet is continuously bent to form functional segments, with the bending angle controlled between 90 and 150 degrees to ensure the range of elastic deformation. The surface of the welding segment 201 can be textured, for example, using laser dotting technology, to increase the contact area with the solder. This embodiment eliminates assembly steps through an integrated molding structure, reducing the accumulation of processing errors and improving overall fatigue resistance. It simplifies the processing flow of the spring structure 2, reduces production costs, and ensures the long-term stability of the terminal clamping force. Since there are no connecting interfaces between the functional segments, no frictional loss occurs during terminal insertion and removal, extending service life. During disassembly and maintenance, the spring structure 2 can be replaced as a whole without disassembling individual components, significantly improving maintenance efficiency.
