Description

Technical Field

[0001] The present application relates to the field of new energy vehicle charging technology, and in particular to a wire outlet structure and device for a high-current vehicle charging port. Background Art

[0002] With the widespread adoption of new energy vehicles, the design and performance of charging ports, the key components connecting electric vehicles to charging equipment, have become crucial. Currently, most mainstream charging ports on the market feature downward-facing cables to reduce cable bends and exposed length, improving the overall aesthetics and ease of use of the charging port.

[0003] Currently, common cable outlet configurations for automotive charging ports on the market primarily involve securing the cable to the charging port terminal by bending the cable or crimping lugs. The crimping lug method uses a crimped lug and screws to secure the cable to the terminal. This method creates a reliable electrical connection by crimping the lug onto the cable and then screwing it onto the terminal. A second approach involves bending the cable directly downward, eliminating the need for intermediaries to connect the terminal and cable directly, thus reducing the need for intermediate components.

[0004] However, the use of crimped lugs and screw-locking connections, coupled with a complex locking structure to secure the cable, results in a cumbersome assembly process with multiple steps and a long assembly time. Furthermore, the lugs and screw-locking structures themselves occupy a certain amount of space, especially since the lugs are thicker. Furthermore, when screwed, more assembly space is required. Directly bending the cable downward requires a sufficient bending radius to avoid damage. Since the cable needs to extend directly from the terminal before being bent and secured, additional space is required to accommodate both the straight-line extension and the bent position. This also requires a longer copper busbar, resulting in high costs. Therefore, a vehicle charging port structure that simplifies the assembly process is provided to address the aforementioned issues.

DETAILED DESCRIPTION

[0045] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0046] It should be noted that when a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component.

[0047] An embodiment of the present application provides a high-current car charging port outlet structure, comprising a first shell and a second shell covering each other;

[0048] The first housing is provided with a first accommodating cavity and a wire outlet communicating with the first accommodating cavity;

[0049] The direction of the first shell toward the second shell is defined as a first direction, and the end surface of the second shell facing away from the first shell is provided with a charging port along the first direction;

[0050] An electrical connection assembly, comprising a terminal and a cable, wherein the terminal comprises a charging portion and a wiring portion arranged in sequence, and the cable passes through the cable outlet and extends out of the first accommodating cavity to be welded to an end of the wiring portion facing away from the charging portion;

[0051] The fixing assembly includes a fixing part and a connecting plate. The fixing part crimps the terminal and fixes it to the connecting plate. The fixing assembly is used to fix the electrical connection assembly into a whole and assemble it into the charging port along the first direction.

[0052] The aforementioned high-current automotive charging port cable outlet structure and device eliminates the need for thick lugs and screws by threading the cables through the outlet and welding them to the terminal connection. The fixture secures the welded terminals to the connecting plate, allowing the entire assembly to be assembled into the charging port at once. This reduces the tedious steps of assembling each component independently and improves assembly efficiency. The electrical connection components are better secured within the housing, resulting in a more compact overall structure and optimized space utilization.

[0053] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0054] See also Figures 1-15 , an embodiment of the present application provides a high-current car charging port outlet structure 100, comprising a first shell 10 and a second shell 20 covering each other;

[0055] The first housing 10 defines a first accommodating cavity 11 and a wire outlet 12 communicating with the first accommodating cavity 11;

[0056] The direction from the first shell 10 toward the second shell 20 is defined as a first direction F1. The end surface of the second shell 20 facing away from the first shell 10 is provided with a charging port 21 along the first direction F1.

[0057] The electrical connection assembly 30 includes a terminal 31 and a cable 32. The terminal 31 includes a charging portion 311 and a wiring portion 313 arranged in sequence. The cable 32 passes through the outlet 12 and extends out of the first accommodating cavity 11 to be welded to the end of the wiring portion 313 facing away from the charging portion 311.

[0058] The fixing assembly 40 includes a fixing part 41 and a connecting plate 42. The fixing part 41 is crimped to fix the terminal 31 and the connecting plate 42. The fixing assembly 40 is used to fix the electrical connection assembly 30 into a whole and assemble it into the charging port 21 along the first direction F1.

[0059] Specifically, the first shell 10 and the second shell 20 cover each other to form a closed structure for protecting the internal electrical connection components 30, while providing structural stability to prevent the external environment from affecting the internal components. A sealing ring is also provided between the two shells. The sealing ring is located at the junction of the first shell 10 and the second shell 20. Through its elastic deformation, it fills the gap between the two shells, which can effectively prevent the entry of external moisture or dust, ensuring the long-term stable operation of the charging interface. The cable 32 passes through the outlet 12 and is electrically welded to the wiring part 313 of the terminal 31. The cable 32 passes through the outlet 12 and is welded to the wiring part 313 to form an electrical connection loop.

[0060] Furthermore, the cables 32 and terminals 31 are welded together to form multiple components, and the connecting plate 42 secures the multiple terminals 31 together as a single unit. This eliminates the tedious steps of individually installing each component in traditional structures, greatly simplifying the assembly process and improving the efficiency and precision of the overall assembly. This design ensures the stability of the electrical connection assembly 30, preventing loosening due to vibration or external forces during use, making it particularly suitable for rapid assembly and efficient operation in high-current scenarios.

[0061] Furthermore, a low-voltage connection interface is provided at the rear end of the connecting plate 42. The connecting plate 42 connects the terminal 31 with the low-voltage connection interface. The design of the connecting plate 42 simplifies the layout of the internal connection and reduces the space occupied by the additional cables 32 and interfaces, thereby improving the internal space utilization, avoiding the complicated wiring of the cables 32, and improving reliability. The fixing part 41 fixes the entire electrical connection assembly 30 into a whole by crimping the connecting plate 42 and the terminal 31, ensuring that the assembly will not loosen or shift during assembly and use. This overall fixing design reduces the steps of independently fixing multiple parts during the assembly process and avoids cumbersome operations. It allows the entire assembly to be assembled into the charging port 21 at one time, making each component modular, saving a lot of time and manpower, and improving assembly efficiency.

[0062] Furthermore, the entire electrical connector assembly 30 is directly assembled and inserted into the charging port 21 along the first direction F1, eliminating the assembly challenges associated with conventional tilted charging port 21 designs. Conventional assembly involves numerous components, requiring assembly from multiple different directions and requiring alignment at multiple angles, which can easily lead to assembly errors and compromise stability and sealing. This design makes assembly of the charging port 21 more direct and smooth, effectively preventing the assembly difficulties and time loss associated with tilting the charging port 21.

[0063] In summary, the outlet structure and device avoids the use of thick wire ears and screw fixing structures by passing the cable 32 through the outlet port 12 and welding it to the wiring portion 313 of the terminal 31, saving internal space. The fixing member 41 fixes the multiple terminals 31 and the connecting plate 42 after welding into a whole, allowing the entire component to be assembled into the charging port 21 at one time, reducing the tedious steps of independently assembling each part and improving assembly efficiency. The design of assembling the entire component into the charging port 21 in the same direction avoids the need to align the angles from multiple directions, which is prone to assembly errors, simplifies the operation, and ensures smooth and stable assembly.

[0064] In a specific embodiment, the terminal 31 further includes a fixing portion 312, which is provided between the charging portion 311 and the wiring portion 313. The fixing portion 312 extends outward along the circumference of the wiring portion 313 to form a fixing surface 312a.

[0065] The fixing member 41 includes a body 411 and a crimping portion 412 that are integrally formed. The body 411 is fixedly connected to the connecting plate 42. The side of the connecting plate 42 facing away from the body 411 is fixedly connected to the terminal 31. The crimping portion 412 fits the fixing surface 312a.

[0066] Specifically, the fixing portion 312 is provided between the charging portion 311 and the wiring portion 313 of the terminal 31 in order to increase structural stability in the electrical connection. This portion extends outward along the circumference of the wiring portion 313 to form a fixing surface 312a. The fixing surface 312a provides a clear fixing position and surface for the subsequent crimping assembly, so that the fixing part 41 can be accurately fitted and crimped on this surface during the assembly process. As a part of the terminal 31, the fixing portion 312 makes the structure of the cable 32 and the terminal 31 more secure after welding through the fixing surface 312a extending therefrom.

[0067] Furthermore, after welding is complete, the terminal 31 and cable 32 are electrically connected via the wiring portion 313. At this point, the fixing portion 312 provides additional mechanical support for the structure of the terminal 31. The fixing portion 312 extends along the circumference of the wiring portion 313 to form a fixing surface 312a, and the fixing member 41 is crimped onto the fixing surface 312a to securely secure the terminal 31 to the connecting plate 42. This structure stabilizes the entire electrical connection assembly 30 and reduces the risk of displacement or loosening of the weld due to external forces, vibration, or mechanical stress during subsequent use.

[0068] Furthermore, the fixing portion 312 is located between the charging portion 311 and the wiring portion 313, and it provides an extended fixing surface 312a for crimping by the fixing part 41. The fixing part 41 is in close contact with the fixing surface 312a of the fixing portion 312 through its crimping portion 412, stably fixing the terminal 31 in one position to prevent the terminal 31 from moving or loosening during operation or use. One side of the connecting plate 42 is fixedly connected to the fixing part 41, and the back side is fixed to the terminal 31. In this way, the connecting plate 42 and the fixing part 41 form a clamping structure, which firmly clamps the terminal 31 in the middle to prevent the welding part from being impacted or damaged by external force.

[0069] Furthermore, the clamping structure provides a bidirectional fixing force, preventing the terminal 31 from loosening or shifting. Once the terminal 31 is fixed, the entire electrical connection assembly 30 forms a single unit and can be assembled into the charging port 21 in one go, simplifying the process and improving assembly efficiency. The clamping design of the fixing member 41 and the connecting plate 42 effectively reduces the direct transmission of external stress to the weld point, thereby improving the long-term stability of the weld.

[0070] In a specific embodiment, the fixing member 41 further includes a first engaging groove 413, the terminal 31 includes a positive terminal 314, a negative terminal 315 and a ground terminal 316, and the crimping portion 412 is attached to the fixing surface 312a of the positive terminal 314 and the negative terminal 315;

[0071] The grounding terminal 316 further includes a second engaging groove 316a that is engaged with the first engaging groove 413. The second engaging groove 316a is annularly arranged on the outer peripheral surface of the fixing portion 312 for fixing the positive terminal 314, the negative terminal 315 and the grounding terminal 316 into a whole.

[0072] Specifically, the first engaging groove 413 is a structure on the fixing member 41 for achieving engagement. Its main purpose is to mechanically engage the grounding terminal 316 of the terminal 31 with the fixing member 41, thereby fixing the positive pole, negative pole and grounding terminal 316 of the terminal 31 to the fixing member 41. It provides mechanical strength, ensures the firmness of the terminal 31 in the fixing member 41, and prevents the terminal 31 from loosening or displacement due to vibration or pulling during use. The design of the engaging groove can achieve standardized assembly of the terminal 31, so that the terminal 31 can be quickly and accurately snapped into place during the assembly process, thereby improving assembly efficiency.

[0073] Furthermore, the second engaging groove 316a increases the stability of the grounding terminal 316 through an annular design, ensuring that the grounding terminal 316 will not loosen due to external pulling or vibration after assembly. This interlocking structure allows the grounding terminal 316 to be firmly fixed in a limited space, ensuring the stability of the overall electrical connection, and facilitating assembly operations and reducing assembly time. The fixing surfaces 312a of the positive terminal 314 and the negative terminal 315 fit tightly with the crimping portion 412 of the fixing member 41, stabilizing the positive and negative terminals 315 in the fixing member 41, forming a stable electrical connection and enhancing the overall firmness. The first engaging groove 413 of the fixing member 41 and the second engaging groove 316a of the grounding terminal 316 of the terminal 31 are interlocked with each other, and the fixing surfaces 312a of the positive terminal 314 and the negative terminal 315 fit tightly with the crimping portion 412 of the fixing member 41, forming a stable overall structure, improving assembly efficiency and structural stability.

[0074] In a specific embodiment, the second housing 20 has a socket 211 connected to the charging port 21 starting along the first direction F1, and the second housing 20 further includes a limit block 22, which is provided on a side of the socket 211 close to the terminal 31;

[0075] The terminal 31 further includes a limiting groove 33 , which is formed on the peripheral surface of the fixing portion 312 . The bottom surface of the limiting groove 33 is perpendicular to the fixing surface 312 a , and the limiting block 22 is fitted into the limiting groove 33 .

[0076] Specifically, the socket 211 is a structure for guiding the electrical connection assembly 30 into the charging port 21, providing a path for the terminal 31 to enter the charging port 21. During the assembly process, the terminal 31 assembly is guided into the charging port 21 along the path of the socket 211. The shell provides a stable guide, so that the electrical connection assembly 30 can be quickly and accurately docked with the charging interface. The limit block 22 is a structure provided on the side of the socket 211 close to the terminal 31. It can be regarded as forming a flat hole in combination with the socket 211. The flat hole formed by the limit block 22 is a special mechanical limit design. It limits the freedom of the terminal 31 through its shape, ensuring that it can only be inserted in a specified direction without offset or rotation. The flat hole structure can effectively lock the movement direction of the terminal 31, prevent the terminal 31 from loosening, rotating or deflecting after assembly, and ensure that it always maintains a precise position and posture.

[0077] Furthermore, a positioning groove is provided on the peripheral surface of the fixing portion 312 of the terminal 31, cooperating with the limiting block 22. During assembly, the limiting groove 33 of the terminal 31 will precisely fit with the limiting block 22 to form a stable mechanical snap-fit ​​structure. The cooperation between the limiting groove 33 and the limiting block 22 provides a dual positioning function, and cooperates with the crimping of the fixing member 41 to stably fix the terminal 31 in the jack 211. The vertical structure can effectively prevent the terminal 31 from twisting or tilting during the installation process, ensuring that the terminal 31 always maintains the correct angle and direction. The vertical limiting design enables a more stable mechanical snap-fit ​​to be formed between the limiting block 22 and the limiting groove 33, and the fixing member 41 can better apply the force to the fixing surface 312a, thereby increasing the overall stability and fixing strength of the terminal 31.

[0078] In one embodiment, the inner wall of the insertion hole 211 is recessed outwardly on one side near the terminal 31 to form a stepped surface 211 a. The peripheral surface of the terminal 31 extends outward to form a boss 34. The boss 34 and the fixing portion 312 enclose a sealing groove 35. The boss 34 abuts against the stepped surface 211 a.

[0079] The electrical connection assembly 30 further includes a first sealing member 36 . The first sealing member 36 is disposed in the sealing groove 35 and is interference-fitted with the inner wall of the insertion hole 211 .

[0080] Specifically, the inner wall of the socket 211, near the terminal 31, is recessed outward to form a stepped surface 211a, which primarily serves to provide a mechanical support point for the terminal 31. The stepped surface 211a contacts the boss 34 of the terminal 31, providing a certain degree of restraint and stability. When inserted into the socket 211, the terminal 31 tightly engages the stepped surface 211a, preventing inward or outward movement of the terminal 31 and ensuring precise positioning of the terminal 31 within the socket 211. Furthermore, the stepped surface 211a provides a stable support surface, further reliably securing the terminal 31.

[0081] Furthermore, the boss 34 not only provides further support for the mechanical fixation of the terminal 31, but also effectively increases the contact area between the terminal 31 and the jack 211, improving the stability and sealing of the connection. The design of the sealing groove 35 provides a standardized position for the subsequent installation of the seal, ensuring that the seal can effectively isolate external impurities. The first seal 36 is located in the sealing groove 35 to prevent the seal from deviating and moving after assembly. The interference fit design ensures that the seal will not loosen due to vibration or long-term use, improving the durability and sealing effect of the interface.

[0082] In a specific embodiment, the connecting portion 313 includes a curved surface portion 313b, the connecting portion 313 is provided with a first welding surface 313a, and the curved surface portion 313b is provided at a corner of the first welding surface 313a;

[0083] The cable 32 is provided with a second welding surface 321, which is attached to and welded to the first welding surface 313a. The central axis of the terminal 31 is defined as a first straight line, and the central axis of the cable 32 is defined as a second straight line. The first straight line and the second straight line are perpendicular to each other.

[0084] Specifically, the design of the wiring portion 313 includes an arc surface portion 313b, which is generally used to improve the overall mechanical strength and electrical conductivity of the welding area. The arc surface design allows the wiring portion 313 to better disperse the stress applied to the welding point, avoiding welding point failure caused by concentrated stress at sharp corners. The flat and sufficient contact area between the second welding surface 321 and the first welding surface 313a facilitates better welding. Compared with spot welding or local welding, the full fit design of the two planes can ensure that the solder is evenly distributed throughout the welding area, thereby improving the strength and stability of the welding point. The large-area welding plane can reduce the contact resistance of the electrical connection, thereby allowing the current to pass through the welding point more smoothly, reducing the heat caused by high resistance.

[0085] Furthermore, the central axis of terminal 31 is perpendicular to the central axis of the cable, meaning that cable 32 and terminal 31 are welded at a 90-degree angle. This 90-degree weld reduces the required bend radius for direct bending and eliminates the need for additional conversion connectors or adapters, thus reducing the number of connection steps between components. This not only simplifies the structural design, but also reduces assembly complexity and potential points of failure, making the entire system more streamlined and efficient.

[0086] Furthermore, this right-angle connection helps maintain better mechanical stability during installation or use, especially in scenarios where frequent plugging and unplugging or vibration is required, which can effectively prevent loosening or solder joint breakage. Due to the full fit between the welding surfaces, this structure provides a large area of ​​electrical contact points, thereby reducing resistance. It can also optimize the current transmission path and significantly improve the current carrying capacity. The large area of ​​the welding surface helps to carry a larger current and reduce the heating or overload problems caused by excessive resistance.

[0087] In a specific embodiment, the outlet 12 includes a first outlet end 121 and a second outlet end 122, and the first outlet end 121 and the second outlet end 122 are both arranged to be tilted downward in the vertical direction;

[0088] When viewed along the first direction F1 , a center line of the first outlet end 121 intersects a center line of the second outlet end 122 .

[0089] Specifically, when viewed from the first direction F1, the centerline of the first outlet terminal 121 intersects the centerline of the second outlet terminal 122. This indicates that the two outlet terminals are not only tilted vertically downward, but also, from a front view, they are not parallel, but intersecting at a certain angle. The crossed centerline design ensures that the cables 32 do not overlap or excessively contact each other when they are output, avoiding interference or entanglement between the cables 32. Especially in high-current applications, it can reduce electromagnetic interference between adjacent cables 32. By crossing the outlets, this design more rationally utilizes limited space, ensures a more orderly layout of the cables 32 inside and outside the device, saves space at the rear of the product, and optimizes the overall structure.

[0090] Furthermore, since the cable outlet is dispersed, the cables 32 are no longer arranged in a centralized manner, reducing the accumulation of cables 32 at the rear, thereby saving space at the rear of the product. Especially in environments that require a compact design, this structure can significantly optimize the overall layout. Since the center lines of the outlets 12 intersect, the arrangement of the cables 32 is no longer limited to a small space, and the arrangement distance is larger, avoiding interference between the cables 32. This decentralized arrangement helps to improve the overall performance of the product, especially in high current scenarios, reducing the risk of heat accumulation. Increasing the distance between the cables 32 allows air to circulate better, improving the heat dissipation effect. For high current application scenarios, good heat dissipation performance is a key factor in ensuring the stable operation of electrical components.

[0091] In a specific embodiment, the electrical connection assembly 30 further includes a second sealing member 37 , which passes through the cable 32 and seals the cable outlet 12 . The cable outlet structure further includes a tail cover 50 .

[0092] The tail cover 50 is snap-connected to the wire outlet 12 , and one end of the second sealing member 37 facing away from the wire outlet 12 abuts against the tail cover 50 .

[0093] Specifically, the second seal 37 is mainly used to seal the connection between the cable 32 and the outlet 12 to prevent moisture, dust and other external contaminants from entering the charging port 21. This sealing structure can effectively protect the internal electrical connection component 30 and ensure its long-term stable operation. The main function of the tail cover 50 is to provide additional protection while forming a reliable connection with the outlet 12. The tail cover 50 is fixed to the outlet 12 by a snap-fit ​​method, which not only ensures the stability of the structure, but also provides a physical barrier for the outlet 12.

[0094] Furthermore, a positioning hole is provided in the tail cap 50. The positioning hole on the tail cap 50 is used to receive and secure the positioning boss 34 at the outlet terminal. During assembly, the positioning hole provides a fixed assembly position for the positioning boss 34, ensuring that the various components can be accurately aligned. This can effectively avoid errors caused by misaligned components during assembly. The combination of the positioning hole and the positioning boss 34 provides clear guidance on the assembly direction and position, reducing assembly errors caused by human factors. The snap-on connection method makes assembly easier and more efficient.

[0095] In a specific embodiment, the second housing 20 further includes an insulating wall 23 . The insulating wall 23 is disposed between the plurality of jacks 211 along the first direction F1 to isolate electrical interference between the plurality of terminals 31 .

[0096] Specifically, the insulating wall 23 is located between the multiple jacks 211, which can effectively isolate the electrical interference between different terminals 31 (such as the positive pole, negative pole and ground terminal 316). This can prevent signal interference and short circuit risks and improve electrical safety. By separating the space between the positive and negative terminals 315, the insulating wall 23 ensures that good electrical performance is maintained even under high current conditions during charging, reducing the risk of arcing and overheating. During the charging process, a stable connection is formed between the electrical connection assembly 30 and the power supply, and the insulating wall 23 ensures safe isolation between each terminal 31. Even during high-speed charging, the current can pass stably, reducing the problem of current leakage or interference.

[0097] In summary, the assembly process of the above-mentioned outlet structure is to first pass the cable 32 through the tail cover 50, the second seal 37 and the outlet 12, and weld it to the terminal 31 at 90 degrees. Confirm that the welding position is correct to ensure the reliability of the electrical connection. The first seal 36 and the pin cap are assembled into the terminal 31, and the terminal 31 and the connecting plate 42 are further connected. First, the engaging groove on the connecting plate 42 is engaged with the ground terminal 316. The fixing member 41 is crimped to the fixing surface 312a of the terminal 31 and fixed to the connecting plate 42 to fix the electrical connection assembly 30 into a whole. Then, they are assembled together into the charging port 21. The fixing member 41 and the connecting plate 42 are fixed to the second shell 20 with screws. After pressing and locking, the first shell 10 and the second shell 20 are covered. The second seal 37 is engaged with the tail cover 50 at the outlet 12. Finally, the low-voltage connector is connected to complete the assembly.

[0098] A high-current car charging port device includes the various structures of the above-mentioned high-current car charging port outlet structure 100. Since this embodiment includes all the features of the above-mentioned embodiments, the above-mentioned embodiment has all the beneficial effects of the above-mentioned embodiments and will not be repeated here.

[0099] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
