Description

Technical Field

[0001] This application relates to the field of power interface technology, and in particular to a power interface device, a power connection component, and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demand from consumers for vehicle comfort and intelligence, the types and number of in-vehicle electrical devices have increased significantly. As a basic standard component for in-vehicle power supply, power interface devices have been widely installed on vehicle interior parts such as the center console, armrest box, and trunk, providing power ports for various in-vehicle electrical devices.

[0003] The power interface device includes a mounting base that is fixed to the interior trim and has an internal socket channel for inserting connectors to provide power connection for in-vehicle electrical equipment.

[0004] In related automotive power interface devices, when the power interface is not in use, a separate screw is typically screwed into the socket channel, relying on the threaded engagement between the screw and the inner wall of the socket channel to achieve a seal. However, this sealing method relies on only a single threaded engagement path, and a helical gap inevitably exists between the screw and the inner wall of the socket channel. Dust, moisture, and other impurities can still enter the socket channel along this gap, resulting in insufficient sealing reliability and making it difficult to meet the protection requirements for long-term use inside a vehicle. Summary of the Invention

[0076] With the rapid development of the automotive industry and the increasing demand from consumers for vehicle comfort and intelligence, the types and number of in-vehicle electrical devices have increased significantly. As a basic standard component for in-vehicle power supply, power interface devices have been widely installed on vehicle interior parts such as the center console, armrest box, and trunk, providing power ports for various in-vehicle electrical devices.

[0077] The power interface device includes a mounting base that is fixed to the interior trim and has an internal socket channel for inserting connectors to provide power connection for in-vehicle electrical equipment.

[0078] In related automotive power interface devices, when the power interface is not in use, a separate screw is typically screwed into the socket channel, relying on the threaded engagement between the screw and the inner wall of the socket channel to achieve a seal. However, this sealing method relies on only a single threaded engagement path, and a helical gap inevitably exists between the screw and the inner wall of the socket channel. Dust, moisture, and other impurities can still enter the socket channel along this gap, resulting in insufficient sealing reliability and making it difficult to meet the protection requirements for long-term use inside a vehicle.

[0079] To address the technical problem of insufficient sealing reliability of the socket channel in related power interface devices, this application proposes a power interface device, including a sealing cover and a mounting base. The sealing cover is located on the side of the vehicle interior trim facing the vehicle interior, and has a first connecting portion extending into the interior trim. The mounting base is located on the side of the interior trim facing the vehicle exterior, and has a conductive portion and a second connecting portion. A socket channel is formed within the second connecting portion; the conductive portion is located on the extension path of the socket channel and is used for electrical connection with a connector inserted into the socket channel. The first connecting portion is used to pass through an installation opening in the interior trim and at least partially insert into the socket channel, and is detachably connected to the second connecting portion, so that the sealing cover closes the installation opening and abuts against the interior trim, while the first connecting portion blocks the socket channel. When the sealing cover is removed from the second connecting portion, the installation opening communicates with the socket channel, allowing the connector to be inserted into the socket channel through the installation opening and electrically connected to the conductive portion.

[0080] The power interface device of this application embodiment achieves a dual sealing mechanism by setting a mating structure of a sealing cover and a mounting base, and by utilizing the design of a first connecting part on the sealing cover passing through the mounting opening and inserting into the socket channel. On one hand, the sealing cover body abuts against the surface of the interior trim, sealing the external opening of the mounting opening; on the other hand, the first connecting part directly blocks the internal space of the socket channel, cutting off the path that dust and moisture may enter the socket channel through the mounting opening. This dual-path sealing method significantly improves the dustproof and waterproof rating of the power interface device, meeting the high reliability protection requirements of long-term vehicle use.

[0081] The technical solution of the application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0082] In the embodiments of this application, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of this application provides a power interface device, including a sealing cover 100 and a mounting base 300.

[0083] The sealing cover 100 is located on the side of the vehicle interior trim 10 facing the interior of the vehicle, and the sealing cover 100 has a first connecting portion 200 extending into the interior trim 10.

[0084] Mounting base 300 is located on the side of interior trim 10 facing the outside of the vehicle. Mounting base 300 is provided with conductive part 400 and second connecting part 500. The second connecting part 500 has a socket channel 510. The conductive part 400 is located on the extension path of the socket channel 510 and is used to electrically connect with the plug 600 inserted into the socket channel 510.

[0085] The first connecting portion 200 is used to pass through the mounting opening of the interior trim 10 and at least partially insert into the socket channel 510, and is detachably connected to the second connecting portion 500 so that the sealing cover 100 covers the mounting opening of the interior trim 10 and abuts against the interior trim 10, and the first connecting portion 200 blocks the socket channel 510.

[0086] When the sealing cover 100 is removed from the second connecting part 500, the mounting opening of the interior trim 10 communicates with the insertion channel 510, so that the plug 600 can be inserted into the insertion channel 510 through the mounting opening of the interior trim 10 and electrically connected to the conductive part 400.

[0087] It should be noted that the interior trim 10 in this application embodiment may generally include, but is not limited to, the following types:

[0088] Trim panels / decorative panels: such as door trim panels, dashboard trim panels, center console side trim panels, B-pillar trim panels, C-pillar trim panels, headliner side trim panels (A-pillar upper guard plate), etc.

[0089] Panels: such as the main instrument panel, center console panel, armrest box cover, etc.

[0090] Other interior trim components: such as headliner, carpets, trunk trim panels, seat side panels, etc.

[0091] This application provides a power interface device, which includes a sealing cover 100 and a mounting base 300. The mounting base 300 is used for fixed installation on a vehicle interior trim piece 10, which may be located on the center console, armrest, or side wall of the trunk, etc. The interior trim piece 10 has a mounting opening for installing the power interface device of this application.

[0092] The sealing cover 100 is located on the side of the vehicle interior trim 10 facing the interior of the vehicle compartment, i.e., the side that the user can directly see and operate. The main body of the sealing cover 100 can cover the mounting opening on the interior trim 10. On the side of the sealing cover 100 facing the interior trim 100, a first connecting portion 200 is integrally formed or fixedly provided. The first connecting portion 200 can be generally cylindrical or tubular in shape, and the outer contour of the first connecting portion 200 matches the insertion hole channel 510.

[0093] The mounting base 300 is located on the side of the interior trim 10 facing the exterior of the vehicle, i.e., in the area hidden inside the trim panel. The mounting base 300 integrates a conductive part 400 and a second connecting part 500. The second connecting part 500 has a socket channel 510 for accommodating an external connector 600, which can be a charging cable connector, data cable connector, conductive cable connector, etc. The conductive part 400 is arranged along the extension path of the socket channel 510, for example, at the bottom or side wall of the socket channel 510, to form an electrical connection with the inserted connector 600, thereby providing power to in-vehicle electrical equipment.

[0094] During installation, the first connecting portion 200 of the sealing cap 100 is aligned with the mounting opening of the interior trim 10, and then passed through the mounting opening of the interior trim 10. It is then at least partially inserted into the insertion channel 510 of the second connecting portion 500 of the mounting base 300. The first connecting portion 200 and the second connecting portion 500 are connected in a detachable manner, such as a snap-fit ​​connection or a threaded connection. When the first connecting portion 200 is fully inserted, on the one hand, the body of the sealing cap 100 will fit tightly against the interior trim 10, completely covering the mounting opening of the interior trim 10; on the other hand, the first connecting portion 200 will fill and seal the internal space of the insertion channel 510, forming an additional sealing barrier. This achieves double sealing protection for the insertion channel 510.

[0095] When the user needs to use the power interface, simply remove the sealing cover 100 from the second connection part 500. At this time, the sealing cover 100 is removed from the interior trim 10, the mounting opening of the interior trim 10 is opened, and the socket channel 510 is also open. The user can directly insert the connector 600 of the external electrical device through the mounting opening of the interior trim 10 into the socket channel 510 and make contact with the conductive part 400 to achieve electrical connection.

[0096] To further improve the sealing effect, an elastic sealing gasket can be provided on the contact surface between the sealing cover 100 and the interior trim 10, or an O-ring can be fitted on the first connecting part 200 of the sealing cover 100 to eliminate assembly gaps.

[0097] The power interface device of this application embodiment achieves a dual sealing mechanism by setting a mating structure between the sealing cover 100 and the mounting base 300, and by utilizing the design of the first connecting portion 200 on the sealing cover 100 passing through the mounting opening of the interior trim 10 and inserting into the socket channel 510. On one hand, the body of the sealing cover 100 abuts against the surface of the interior trim 10, sealing the external opening of the interior trim 10's mounting opening; on the other hand, the first connecting portion 200 directly blocks the internal space of the socket channel 510, cutting off the path that dust and moisture may enter the interior of the socket channel 510 through the mounting opening of the interior trim 10. This dual-path sealing method significantly improves the dustproof and waterproof rating of the power interface device, meeting the high reliability protection requirements of long-term vehicle use environments.

[0098] Furthermore, the structural design cleverly integrates the installation and sealing functions of the sealing cover 100 into one unit. Users do not need additional separate parts (such as screws in related technologies); they can simply operate the sealing cover 100 to open and close the power interface. This simple operation avoids the risk of losing small parts and enhances the user experience.

[0099] Since the first connecting part 200 and the second connecting part 500 are detachably connected, the sealing cover 100 is easy to install and remove. This ensures that when needed, the plug 600 can be smoothly inserted into the socket channel 510 and establish a reliable electrical connection with the conductive part 400 without affecting the normal function of the power interface.

[0100] Furthermore, when the sealing cover 100 and the mounting base 300 are assembled, the body of the sealing cover 100 is tightly fitted against the side surface of the interior trim 10 facing the interior of the vehicle compartment, while the mounting base 300 abuts against the side surface of the interior trim 10 facing the exterior of the vehicle. After the first connecting part 200 passes through the mounting opening of the interior trim 10 and is inserted into the socket channel 510, the axial tension generated by the detachable connection between the first connecting part 200 and the second connecting part 500 causes the sealing cover 100 and the mounting base 300 to apply pressure from both sides of the interior trim 10, thereby firmly clamping and fixing the interior trim 10 between the sealing cover 100 and the mounting base 300. This clamping and fixing method eliminates the need for additional screws, rivets, or other independent fasteners, simplifying the assembly process, reducing parts costs, and ensuring the positioning accuracy and vibration resistance of the power interface device on the interior trim 10, preventing loosening or abnormal noise caused by vehicle vibration.

[0101] In another embodiment, reference Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, it also includes a mounting sleeve 700, which is disposed within the socket channel 510. At least a portion of the first connecting portion 200 is detachably connected to the mounting sleeve 700 to form a detachable connection between the first connecting portion 200 and the second connecting portion 500.

[0102] In this embodiment, the power interface device further includes a mounting sleeve 700. The mounting sleeve 700 is generally cylindrical, and its outer contour matches the insertion channel 510 within the second connecting portion 500. The mounting sleeve 700 is fixedly disposed within the insertion channel 510, for example, by interference fit, bonding, or snap-fit. The outer contour of the first connecting portion 200 conforms to the shape of the inner cavity of the mounting sleeve 700. When the first connecting portion 200 of the sealing cover 100 passes through the mounting opening of the interior trim 10 and is inserted into the insertion channel 510, at least a portion of the first connecting portion 200 extends into the mounting sleeve 700 and forms a detachable connection with the inner wall of the mounting sleeve 700, for example, through threaded engagement or snap-fit ​​engagement. In this way, the first connecting part 200 is not directly connected to the inner wall of the insertion channel 510 of the second connecting part 500, but is indirectly connected through the intermediate component mounting sleeve 700, thereby forming a detachable connection relationship between the first connecting part 200 and the second connecting part 500.

[0103] In this embodiment, firstly, the mounting sleeve 700, as an independent part, can be made of a different material than the second connecting part 500. For example, engineering plastics or metal materials with better wear resistance or lower coefficient of friction can be selected, thereby effectively reducing the wear on the inner wall of the socket channel 510 during repeated insertion and removal of the first connecting part 200 and extending the service life of the entire power interface device.

[0104] Secondly, the mounting sleeve 700 can provide more precise guidance and positioning for the first connecting part 200, ensuring that the first connecting part 200 can be accurately centered and locked each time it is inserted or removed. This improves the smoothness of the installation and removal of the sealing cover 100 and the accuracy of repeated positioning, and avoids the sealing effect being affected by loosening or misalignment of the connection due to long-term use.

[0105] Furthermore, the mounting sleeve 700 itself can be replaced independently. When the mounting sleeve 700 wears or is damaged due to long-term use, it is not necessary to replace the entire mounting base 300. Simply remove the old mounting sleeve 700 and install the new mounting sleeve 700 to restore good connection performance, reducing maintenance costs and difficulty.

[0106] Furthermore, the presence of the mounting sleeve 700 changes the connection interface between the first connecting part 200 and the second connecting part 500 from a single contact surface to two contact surfaces inside and outside the mounting sleeve 700, increasing the length and tortuosity of the sealing path. This helps to further prevent dust and moisture from invading the interior of the socket channel 510 along the connection gap, thereby enhancing the overall sealing reliability.

[0107] In other possible embodiments, refer to Figure 4 , Figure 5 and Figure 6 As shown, the inner wall of the mounting sleeve 700 is provided with a first internal thread 710, and at least a portion of the outer wall of the first connecting part 200 is provided with a first external thread 220 that mates with the first internal thread 710; the first connecting part 200 is connected to the mounting sleeve 700 through the mating of the first external thread 220 and the first internal thread 710.

[0108] In this embodiment, when the first connecting portion 200 of the sealing cap 100 is inserted into the mounting sleeve 700, the sealing cap 100 is rotated to engage the first external thread 220 with the first internal thread 710, thereby achieving a threaded connection between the first connecting portion 200 and the mounting sleeve 700. This threaded connection allows the sealing cap 100 to be stably fixed on the mounting base 300, and installation and removal can be easily achieved by rotating the sealing cap 100 in either the forward or reverse direction. The engagement depth of the threaded connection can be adjusted as needed to ensure that the sealing cap 100 fits tightly against the surface of the interior trim 10, while the first connecting portion 200 fully blocks the insertion hole channel 510.

[0109] In this embodiment, the threaded connection has a self-locking characteristic, providing a stable and reliable axial locking force. Even under vibration or impact during vehicle operation, the sealing cap 100 is not easily loosened, ensuring the continued effectiveness of the seal during long-term use.

[0110] Furthermore, the threaded fit allows users to install and remove the sealing cap 100 with a simple rotation operation, without the need for tools, making the operation convenient and labor-saving, and improving the user experience.

[0111] Meanwhile, during the thread engagement process, the sealing cap 100 can gradually press the surface of the interior trim 10, generating a controllable pre-tightening force, which helps to eliminate the assembly gap between the sealing cap 100 and the interior trim 10, further enhancing the sealing effect of the installation opening of the interior trim 10.

[0112] Moreover, the engagement depth of the threaded connection is adjustable, which can accommodate interior trim parts 10 of different thicknesses, thus improving the universality and adaptability of the power interface device to interior trim parts 10 of different models.

[0113] In another possible embodiment, refer to Figure 1 and Figure 3 As shown, the sealing cover 100 has a tool interface 120 on the side away from the interior trim 10. The tool interface 120 is used to cooperate with an external tool to release the detachable connection between the first connecting part 200 and the second connecting part 500.

[0114] In this embodiment, a tool interface 120 is provided on the side of the sealing cover 100 away from the interior trim 10, that is, on the outer surface facing the interior of the vehicle and accessible to the user. The tool interface 120 can be a groove, a protrusion, a polygonal hole, or a Phillips head, etc., its specific form matching a pre-set external tool. For example, the tool interface 120 can be a slotted head, a Phillips head, a hexagonal hole, or a star-shaped groove. When it is necessary to disengage the detachable connection between the first connecting part 200 and the second connecting part 500, the user can insert or fit a corresponding external tool, such as a screwdriver, wrench, or special key, into or onto the tool interface 120, and then apply rotational or pulling force to easily remove the sealing cover 100 from the mounting base 300. The tool interface 120 allows for easy removal even when the sealing cover 100 is jammed due to long-term use or difficult to manually unscrew due to dirt accumulation.

[0115] In this embodiment, the tool interface 120 provides the user with an additional point of force application, so that when the connection resistance between the sealing cover 100 and the mounting base 300 increases due to prolonged static placement, thermal expansion and contraction, or dirt adhesion, the user can easily disengage the connection by lever principle or with greater torque, avoiding user inconvenience or forced damage to the sealing cover 100 caused by the inability to disassemble by hand.

[0116] Moreover, the tool interface 120 is compatible with a variety of common tools, such as coins, screwdrivers, or special keys, allowing users to complete the operation without carrying special equipment, thus improving the convenience of daily use and operability in emergency situations.

[0117] Furthermore, the tool interface 120 can be designed in a non-standard shape, such as a groove with a specific pattern, which can play a certain role in preventing misoperation or theft, preventing unauthorized personnel from disassembling the power interface device at will, and improving security.

[0118] Meanwhile, the presence of the tool interface 120 does not affect the aesthetic appearance of the sealing cover 100. It can be designed as a hidden structure flush with the surface of the sealing cover 100, keeping it flat when not in use, without taking up extra space, and without affecting the sealing function of the sealing cover 100.

[0119] In other possible embodiments, refer to Figure 1 and Figure 3 As shown, the tool interface 120 is a screwdriver interface, which is used to engage with a screwdriver to drive the sealing cover 100 to rotate relative to the mounting base 300.

[0120] In this embodiment, the screwdriver interface is shaped to match the tip of a conventional screwdriver, such as a slotted, Phillips, hex, or Torx screw. When it is necessary to disconnect the detachable connection between the first connecting part 200 and the second connecting part 500, the user inserts the tip of a screwdriver of the appropriate size into the screwdriver interface. By rotating the screwdriver handle, the rotational torque is transmitted to the sealing cover 100, thereby driving the sealing cover 100 to rotate relative to the mounting base 300, thus loosening or tightening the threads between the first connecting part 200 and the mounting sleeve 700 or the second connecting part 500. The screwdriver interface makes the installation and removal of the sealing cover 100 more effortless and precise.

[0121] In this embodiment, screwdrivers are a very common and readily available tool. Both home users and repair personnel usually carry screwdrivers with them or keep them on hand. Therefore, users do not need to look for special tools when they need to remove the sealing cover 100, which greatly improves the convenience and universality of operation.

[0122] Furthermore, the screwdriver interface can effectively transmit a large torsional torque. When the sealing cover 100 generates a large frictional force with the mounting base 300 due to long-term use, dirt adhesion, or thermal expansion and contraction, the user can still easily rotate the sealing cover 100 with the help of the screwdriver's leverage, ensuring the reliability of disassembly.

[0123] Meanwhile, the screwdriver interface adopts a standardized design, which is compatible with the vast majority of screwdrivers on the market. Users do not need to worry about incompatibility between the interface and the tool, thus lowering the barrier to entry.

[0124] Furthermore, by driving the sealing cover 100 to rotate with a screwdriver, precise angle control and stable force can be achieved, avoiding the misalignment of the sealing cover 100 or damage to the threads caused by uneven force when tightening by hand, which is beneficial to protecting the long-term service life of the connection structure.

[0125] In other possible embodiments, refer to Figure 5 , Figure 6 and Figure 7 As shown, the mounting sleeve 700 is fixed in the socket channel 510 by a snap-fit ​​structure; the snap-fit ​​structure includes a first snap-fit ​​part 720 disposed on the outer wall of the mounting sleeve 700, and a second snap-fit ​​part 511 disposed on the inner wall of the socket channel 510 and cooperating with the first snap-fit ​​part 720.

[0126] In this embodiment, the mounting sleeve 700 is fixed within the insertion channel 510 by a snap-fit ​​structure. This snap-fit ​​structure includes a first snap-fit ​​portion 720 and a second snap-fit ​​portion 511. The first snap-fit ​​portion 720 is disposed on the outer wall of the mounting sleeve 700, and may be, for example, one or more radially outwardly protruding buckles, elastic claws, or annular rings. The second snap-fit ​​portion 511 is correspondingly disposed on the inner wall of the insertion channel 510, and may be, for example, a groove, recess, or stepped surface matching the shape of the first snap-fit ​​portion 720. When the mounting sleeve 700 is pushed into the insertion channel 510 to a predetermined position, the first snap-fit ​​portion 720 and the second snap-fit ​​portion 511 engage or hook with each other, thereby firmly positioning the mounting sleeve 700 within the insertion channel 510 and preventing it from shifting or dislodging in the axial direction.

[0127] The first locking part 720 and the second locking part 511 can be designed as an irreversible one-time locking or as a detachable elastic locking to facilitate subsequent maintenance and replacement.

[0128] In this embodiment, the snap-fit ​​structure enables the rapid installation of the mounting sleeve 700 without the need for additional screws, glue, or welding processes. The mounting sleeve 700 can be fixed simply by pressing it into the insertion channel 510, which greatly simplifies the assembly process, improves production efficiency, and reduces manufacturing costs.

[0129] Furthermore, the snap-fit ​​structure provides a reliable axial locking force through mechanical engagement, which can effectively resist the axial tension generated during the insertion and removal of the sealing cover 100, ensuring that the mounting sleeve 700 will not loosen or shift during use, and guaranteeing the long-term stability of the connection between the first connecting part 200 and the mounting sleeve 700.

[0130] Meanwhile, the snap-fit ​​structure can adopt an elastic snap-fit ​​design, which allows the 700 mounting sleeve to be disassembled when necessary, facilitating later maintenance or replacement, thus balancing the firmness of the installation with the convenience of maintenance.

[0131] Moreover, the snap-fit ​​structure eliminates the need for additional sealing material between the mounting sleeve 700 and the socket channel 510, avoiding the risk of seal failure due to adhesive aging or welding deformation, and helps maintain the original sealing performance inside the socket channel 510.

[0132] In other embodiments, refer to Figure 5 , Figure 6 and Figure 7 As shown, the first snap-fit ​​portion 720 consists of a plurality of protrusions spaced apart circumferentially along the outer wall of the mounting sleeve 700; the second snap-fit ​​portion 511 consists of a plurality of grooves spaced apart circumferentially along the inner wall of the insertion hole channel 510, with the protrusions engaging with the grooves.

[0133] In this embodiment, the first engaging portion 720 is specifically configured as a plurality of protrusions spaced apart circumferentially along the outer wall of the mounting sleeve 700. These protrusions can be hemispherical, trapezoidal, or rectangular, and are evenly or unevenly distributed on the outer circumference of the mounting sleeve 700. The second engaging portion 511 is correspondingly configured as a plurality of grooves spaced apart circumferentially along the inner wall of the insertion channel 510, the position, number, and shape of the grooves matching the protrusions. When the mounting sleeve 700 is pushed into the insertion channel 510, each protrusion undergoes elastic deformation or is squeezed under the action of external force until it reaches the position of the groove, at which point the protrusion springs into or embeds into the groove, achieving engagement between the protrusion and the groove. This engagement allows the mounting sleeve 700 to be positioned in both the axial and circumferential directions, preventing the mounting sleeve 700 from rotating or moving axially relative to the insertion channel 510.

[0134] In this embodiment, the engagement of multiple protrusions and grooves forms a multi-point engagement structure. Compared with single-point engagement, this structure can distribute the force, providing a more uniform and stable fixing effect, and effectively preventing the mounting sleeve 700 from deflecting or tilting when subjected to torsion or axial tension.

[0135] Furthermore, the circumferential spacing creates gaps between the protrusions and the grooves, which can serve as exhaust channels. When the mounting sleeve 700 is pressed into the insertion channel 510, internal air is allowed to escape, avoiding installation difficulties caused by air pressure accumulation. It also facilitates subsequent possible drainage or ventilation.

[0136] Meanwhile, the multi-point engagement creates multiple local contacts between the mounting sleeve 700 and the inner wall of the insertion channel 510, reducing the continuous contact area, lowering the insertion resistance during installation, and making the assembly process smoother and less strenuous.

[0137] In other possible embodiments, refer to Figure 4 As shown, the sealing cover 100 has a first elastic layer 800 on its surface for contacting the interior trim 10.

[0138] In this embodiment, the first elastic layer 800 can be made of rubber, silicone, thermoplastic elastomer, or other materials with good elasticity and weather resistance. The first elastic layer 800 can be fixed to the contact surface of the sealing cover 100 by means of bonding, vulcanization, two-color injection molding, or overmolding to form a continuous elastic gasket. When the sealing cover 100 is connected to the mounting base 300 through the first connecting part 200 and covers the mounting opening of the interior trim 10, the first elastic layer 800 is pressed between the sealing cover 100 and the interior trim 10, undergoing elastic deformation, thereby tightly filling the microscopic gap between them.

[0139] In this embodiment, the first elastic layer 800 can adaptively fill the uneven area between the sealing cover 100 and the interior trim 10 after being compressed, effectively eliminating the tiny gaps caused by manufacturing tolerances or surface roughness, significantly improving the sealing performance at the installation opening of the interior trim 10, and preventing dust, moisture and noise from entering the interior of the vehicle from there.

[0140] Furthermore, the first elastic layer 800 has a good elastic buffering effect, which can absorb vibration and impact during vehicle operation, reduce rigid collision between the sealing cover 100 and the interior parts 10, avoid abnormal noise, and improve ride comfort.

[0141] Meanwhile, the first elastic layer 800 can prevent the sealing cover 100 from making direct hard contact with the surface of the interior trim 10, avoiding scratches or wear on the paint or decorative layer of the interior trim 10 during repeated disassembly and assembly, thus protecting the aesthetics of the vehicle interior.

[0142] Furthermore, the first elastic layer 800 can compensate for the thermal expansion and contraction caused by temperature changes, maintaining appropriate compression force under different climatic conditions to ensure the long-term stability of the sealing effect.

[0143] In other possible embodiments, the side of the first elastic layer 800 facing the interior trim 10 is provided with at least one annular sealing rib (not shown in the figure).

[0144] In this embodiment, at least one annular sealing rib is provided on the side of the first elastic layer 800 facing the interior trim 10. The annular sealing rib protrudes axially from the surface of the first elastic layer 800, and its cross-sectional shape can be semi-circular, triangular, trapezoidal, or rectangular. There can be one or multiple concentric annular ribs with different diameters, arranged in a nested pattern. When the sealing cover 100 is connected to the mounting base 300 via the first connecting portion 200 and presses against the interior trim 10, the annular sealing rib preferentially contacts the surface of the interior trim 10 and undergoes elastic compression deformation under the pressure, forming one or more continuous annular sealing lines.

[0145] In this embodiment, the annular sealing rib can generate a higher local contact stress than the planar elastic layer when pressed, thereby achieving effective sealing with a smaller pressing force, reducing the locking force required for the sealing cover 100, and making the operation easier.

[0146] Furthermore, when multiple concentric annular sealing ribs are installed, each rib forms an independent sealing ring, creating multiple lines of sealing protection. Even if the outermost rib fails due to foreign objects or scratches, the inner ribs can still maintain the seal, significantly improving the redundancy and reliability of the seal.

[0147] Meanwhile, the annular sealing rib can better adapt to the microscopic unevenness of the surface of the interior trim 10, and fill the recessed or raised areas through local elastic deformation, thus making up for the risk of local leakage that may exist in the planar elastic layer. It is especially suitable for interior trim 10 with complex or rough surface texture.

[0148] Furthermore, the structure of the annular sealing rib increases the sealing path length of the sealing interface, requiring external dust and moisture to bypass more obstacles before intruding, effectively slowing down the penetration rate of impurities and improving long-term protective performance.

[0149] In other embodiments, the number of annular sealing ribs is at least two, and each annular sealing rib is concentrically arranged with the axis of the insertion hole channel 510 as the center, and the diameter of each annular sealing rib increases sequentially from the inside to the outside.

[0150] In this embodiment, the number of annular sealing ribs is set to at least two. Each annular sealing rib is arranged concentrically around the axis of the insertion channel 510, and the diameter of each annular sealing rib increases sequentially from the inside to the outside, forming a set of annular protrusions that gradually expand from the inner circle to the outer circle. For example, the first annular sealing rib is provided at the innermost position closest to the axis of the insertion channel 510, and the second annular sealing rib is provided at a certain distance around it, and so on. An annular groove area is formed between adjacent annular sealing ribs. When the sealing cover 100 is connected to the mounting base 300 through the first connecting part 200 and presses against the interior trim 10, all annular sealing ribs contact the surface of the interior trim 10 and undergo elastic compression, each forming an independent annular sealing line.

[0151] In this embodiment, multiple concentric annular sealing ribs form multiple independent annular sealing lines, constituting a progressively layered sealing barrier. The innermost sealing rib undertakes the primary sealing task. When external dust or moisture breaks through the first line of defense, each subsequent sealing rib can continue to intercept it, significantly improving the redundancy and long-term reliability of the seal.

[0152] Furthermore, the layout with diameters increasing from the inside out ensures a more uniform pressure distribution across the sealing ribs during compression. The inner ribs, with their smaller diameter, experience more concentrated compression force per unit length, while the outer ribs provide wider-range support. Together, they prevent excessive localized stress that could lead to premature fatigue failure of the elastic layer.

[0153] Furthermore, the grooved areas between adjacent annular sealing ribs form miniature water storage tanks or dust storage tanks, which can temporarily accommodate a small amount of intruding water or dust particles, preventing them from directly crossing the sealing boundary and entering the insertion channel 510, thus playing a buffering and intercepting role.

[0154] Meanwhile, the layout of multiple concentric sealing ribs can adapt to different degrees of undulation and deformation on the surface of the interior trim 10. Even if there are slight depressions or protrusions in a part of the interior trim 10, there will always be one or more sealing ribs that can fit tightly against it, ensuring that the overall sealing effectiveness is not affected by a single poor contact.

[0155] In some embodiments, reference is made to Figure 2 ,and Figure 7 As shown, the mounting base 300 is also provided with a mounting cavity 310, which is located at the end of the insertion channel 510 away from the interior trim 10 and is connected to the insertion channel 510. The conductive part 400 is located in the mounting cavity 310.

[0156] In this embodiment, the mounting base 300 is further provided with a mounting cavity 310. The mounting cavity 310 is located at the end of the socket channel 510 away from the interior trim 10, i.e., the end position of the socket channel 510, and is interconnected with the socket channel 510 to form a through-hole accommodating space. A conductive part 400 is disposed within the mounting cavity 310. The conductive part 400 may include electrical components such as conductive terminals, conductive springs, or circuit boards, for forming an electrical connection with the plug 600 inserted into the socket channel 510. The mounting cavity 310 provides an independent accommodating space for the conductive part 400, isolating it from other areas of the socket channel 510, while maintaining an electrical path with the socket channel 510 through a connecting port.

[0157] In this embodiment, the mounting cavity 310 provides a dedicated mounting space for the conductive part 400, avoiding direct exposure of the conductive part 400 to the main channel of the socket channel 510. This effectively reduces accidental collisions or scratches to the conductive part 400 when the connector 600 is inserted, protecting the structural integrity and electrical performance of the conductive part 400.

[0158] Furthermore, the mounting cavity 310 is connected to the socket channel 510 but relatively independent, which creates a certain isolation distance between the conductive part 400 and the inner wall of the socket channel 510. This helps prevent dust, moisture or metal debris from directly contacting the key contact surface of the conductive part 400, reducing the risk of short circuits or poor contact and improving the reliability of the electrical connection.

[0159] Furthermore, the structure of the mounting cavity 310 facilitates the modular installation and fixation of the conductive part 400. The conductive part 400 can be pre-assembled into the mounting cavity 310 before assembly, and then the whole assembly can be installed into the mounting base 300, which simplifies the production process and improves assembly efficiency.

[0160] Meanwhile, the mounting cavity 310 makes the position of the conductive part 400 more definite and stable, providing a clear insertion termination position for the connector 600, ensuring that the connector 600 can accurately mate with the conductive part 400, and avoiding connection failure caused by insufficient insertion depth or over-insertion.

[0161] A second aspect of this application provides a power connection assembly, including the power interface device and connector 600 of any of the above embodiments.

[0162] The connector 600 is detachably inserted into the socket channel 510 of the power interface device and electrically connected to the conductive part 400 of the power interface device.

[0163] Since the power connection assembly of this application embodiment includes the power interface device of any of the above embodiments, the power interface device includes a sealing cover 100 and a mounting base 300. The sealing cover 100 is provided on the side of the vehicle interior trim 10 facing the vehicle interior, and the sealing cover 100 has a first connecting portion 200 extending towards the interior trim 10. The mounting base 300 is provided on the side of the interior trim 10 facing the vehicle exterior, and the mounting base 300 has a conductive portion 400 and a second connecting portion 500. The second connecting portion 500 has an insertion hole channel 510. The conductive portion 400 is located on the extension path of the insertion hole channel 510 and is used to electrically connect with the plug 600 inserted into the insertion hole channel 510. The first connecting portion 200 is used to pass through the installation opening of the interior trim 10 and at least partially insert into the insertion hole channel 510, and is detachably connected to the second connecting portion 500 so that the sealing cover 100 covers the installation opening of the interior trim 10 and abuts against the interior trim 10, and the first connecting portion 200 blocks the insertion hole channel 510. When the sealing cover 100 is removed from the second connecting part 500, the mounting opening of the interior trim 10 communicates with the insertion channel 510, so that the plug 600 can be inserted into the insertion channel 510 through the mounting opening of the interior trim 10 and electrically connected to the conductive part 400.

[0164] The power interface device of the power connection assembly in this application embodiment achieves a dual sealing mechanism by setting a mating structure of a sealing cover 100 and a mounting base 300, and by utilizing the design of a first connecting portion 200 on the sealing cover 100 passing through the mounting opening of the interior trim 10 and inserting into the socket channel 510. On one hand, the body of the sealing cover 100 abuts against the surface of the interior trim 10, sealing the external opening of the interior trim 10's mounting opening; on the other hand, the first connecting portion 200 directly blocks the internal space of the socket channel 510, cutting off the path that dust and moisture may enter the socket channel 510 through the mounting opening of the interior trim 10. This dual-path sealing method significantly improves the dustproof and waterproof rating of the power interface device, meeting the high reliability protection requirements of long-term vehicle use environments.

[0165] In some embodiments, reference is made to Figure 2As shown, the inner wall of the socket channel 510 of the power interface device is provided with a first internal thread 710, and the outer wall of the plug 600 is provided with a third external thread 640. The third external thread 640 is used to engage with the first internal thread 710 after the sealing cover 100 is removed from the mounting base 300, so as to thread the plug 600 into the socket channel 510.

[0166] In this embodiment, the inner wall of the socket channel 510 of the power interface device is provided with a first internal thread 710. This first internal thread 710 can be directly formed on the inner wall of the socket channel 510 of the second connecting part 500, or it can be indirectly provided through the mounting sleeve 700; that is, the first internal thread 710 on the inner wall of the mounting sleeve 700 is equivalent to the thread structure of the inner wall of the socket channel 510. The outer wall of the connector 600 is provided with a third external thread 640 that mates with the first internal thread 710. When the user needs to use the power interface, the sealing cover 100 is first removed from the mounting base 300, allowing the mounting opening of the interior trim 10 to connect with the socket channel 510. Subsequently, the connector 600 is aligned with the mounting opening of the interior trim 10 and inserted into the socket channel 510. By rotating the connector 600, the third external thread 640 and the first internal thread 710 are screwed together, thereby threading the connector 600 into the socket channel 510. After being screwed into place, the end of the connector 600 contacts the conductive part 400 in the mounting cavity 310 and establishes an electrical connection, thereby enabling power supply to the electrical equipment.

[0167] In this embodiment, the threaded connection provides a reliable axial locking force, which enables the connector 600 to be firmly fixed in the socket channel 510 after insertion, effectively resisting vibration and impact during vehicle operation, preventing the connector 600 from accidentally falling off and causing power outage, and improving the stability and safety of the power connection.

[0168] Moreover, the thread engagement process is equivalent to gradually pulling the connector 600 into the depth of the socket channel 510, ensuring that the connector 600 and the conductive part 400 maintain a stable contact pressure, reducing contact resistance, reducing the risk of heating or arcing caused by poor contact, and improving the efficiency and quality of power transmission.

[0169] Meanwhile, the threaded fit forms a multi-turn spiral contact between the outer wall of the connector 600 and the inner wall of the socket channel 510, which increases the length of the sealing path and helps to prevent dust and moisture from entering along the gap between the connector 600 and the socket channel 510, thus enhancing the protective performance in the plugged state.

[0170] Furthermore, users can easily install and remove the connector 600 with a simple rotation operation, without the need for additional tools. The operation is convenient and consistent with the installation and removal method of the sealing cover 100, forming a unified operating habit and improving the user experience.

[0171] In other embodiments, refer to Figure 16 and Figure 17 As shown, the outer periphery of the connector 600 away from the socket channel 510 is provided with an abutment portion 650 extending radially outward; when the connector 600 is inserted into the socket channel 510 to a predetermined position, the abutment portion 650 covers the installation opening of the interior trim 10 and abuts against the side of the interior trim 10 facing the vehicle interior.

[0172] In this embodiment, the end of the connector 600 furthest from the socket channel 510, that is, the end facing the interior of the vehicle and used by the user for holding or connecting cables, has a radially outwardly extending abutment portion 650 on its outer periphery. This abutment portion 650 can be an annular flange, a flange, or a skirt structure, with an outer diameter larger than the size of the mounting opening of the interior trim 10. When the connector 600 is screwed into the socket channel 510 through the engagement of the third external thread 640 and the first internal thread 710 and reaches a predetermined position, the abutment portion 650 precisely covers the mounting opening of the interior trim 10 and tightly abuts against the side surface of the interior trim 10 facing the vehicle interior. The shape of the abutment portion 650 can be similar to the sealing cap 100, making it visually integrated with the interior trim 10. An elastic layer or sealing ribs can also be provided on the side of the abutment portion 650 facing the interior trim 10 to further enhance the sealing effect.

[0173] In this embodiment, the abutment portion 650 closes the mounting opening of the interior trim 10 when the connector 600 is in use, preventing dust, moisture or debris from entering the socket channel 510 through the mounting opening of the interior trim 10. Even when the connector 600 is plugged in for a long time, the internal of the power interface device can be kept clean, extending the service life of the conductive part 400.

[0174] Meanwhile, the abutting part 650 abuts against the surface of the interior trim 10, providing additional axial support for the connector 600, making the connector 600 more stable after insertion, reducing shaking or loosening caused by vehicle vibration, and improving the reliability of the electrical connection.

[0175] Furthermore, after the abutment part 650 covers the installation opening of the interior trim 10, the installation opening of the interior trim 10 is completely covered when viewed from inside the vehicle, resulting in a neat and uniform appearance. This avoids the exposed installation opening of the interior trim 10 affecting the aesthetics of the interior and enhances the sense of quality of the vehicle.

[0176] Moreover, the connecting part 650 has a similar function to the sealing cover 100, but unlike the sealing cover 100, it does not need to be stored separately when not in use. The connector 600 itself has the ability to close the installation opening of the interior trim 10, which simplifies the user operation and avoids the risk of losing the sealing cover 100.

[0177] In other possible embodiments, refer to Figure 16 and Figure 17 As shown, the abutment portion 650 has a second elastic layer 660 on the surface that contacts the interior trim 10.

[0178] In this embodiment, a second elastic layer 660 is provided on the surface of the abutment portion 650 that contacts the interior trim 10. This second elastic layer 660 can be made of rubber, silicone, thermoplastic elastomer, or other materials with good elasticity and weather resistance. The second elastic layer 660 can be fixed to the contact surface of the abutment portion 650 by means of bonding, vulcanization, two-color injection molding, or overmolding, forming a continuous elastic pad. When the connector 600 is screwed into the insertion hole channel 510 through the engagement of the third external thread 640 and the first internal thread 710 and reaches the predetermined position, the abutment portion 650 covers the mounting opening of the interior trim 10 and abuts against the surface of the interior trim 10. At this time, the second elastic layer 660 is pressed between the abutment portion 650 and the interior trim 10, undergoing elastic deformation, thereby tightly filling the microscopic gap between them.

[0179] In this embodiment, the second elastic layer 660 can adaptively fill the uneven area between the abutment portion 650 and the interior trim 10 after being compressed, effectively eliminating the tiny gaps caused by manufacturing tolerances or surface roughness, significantly improving the sealing performance of the installation opening of the interior trim 10 when the connector 600 is in use, and preventing dust, moisture and noise from invading the interior of the vehicle or the connector channel 510 from there.

[0180] Moreover, the second elastic layer 660 has a good elastic buffering effect, which can absorb vibration and impact during vehicle operation, reduce rigid collision between the contact part 650 and the interior part 10, avoid abnormal noise, and improve ride comfort.

[0181] Meanwhile, the second elastic layer 660 can prevent the contact part 650 from making direct hard contact with the surface of the interior trim 10, avoiding scratches or wear on the paint or decorative layer of the interior trim 10 during repeated insertion and removal, thus protecting the aesthetics of the vehicle interior.

[0182] Furthermore, the second elastic layer 660 can also compensate for the thermal expansion and contraction caused by temperature changes, and maintain appropriate compression force under different climatic conditions to ensure that the sealing effect between the contact part 650 and the interior part 10 is stable and reliable in the long term.

[0183] A third aspect of this application provides a vehicle, including the power interface device or power connection component of any of the above embodiments.

[0184] Since the vehicle in this application embodiment is equipped with a power interface device or a power connection assembly as described in any of the above embodiments, a double sealing mechanism is achieved by setting a mating structure between the sealing cover 100 and the mounting base 300, and by utilizing the design of the first connecting portion 200 on the sealing cover 100 passing through the mounting opening of the interior trim 10 and inserting into the socket channel 510. On one hand, the body of the sealing cover 100 abuts against the surface of the interior trim 10, sealing the external opening of the interior trim 10's mounting opening; on the other hand, the first connecting portion 200 directly blocks the internal space of the socket channel 510, cutting off the path that dust and moisture may enter the interior of the socket channel 510 through the mounting opening of the interior trim 10. This dual-path sealing method significantly improves the dustproof and waterproof rating of the power interface device, meeting the high reliability protection requirements of the vehicle under long-term use conditions.

[0185] In another embodiment, the vehicle includes a body, the body includes a center console, and a power interface device is disposed on the center console.

[0186] In this embodiment, the power interface device can be located on the front panel of the center console, near the gear lever operating area, or inside the storage compartment. In this location, the sealing cover 100 forms part of the center console panel, blending with the interior design. The mounting bracket 300 is mounted on the internal frame or support structure of the center console. Typically, this location uses a "forward mounting" method, utilizing the positioning rib 1100 on the mounting bracket 300 to engage with the first support plate inside the center console for pre-positioning.

[0187] In another embodiment, the vehicle body includes a roof, and a power interface device is disposed on the roof.

[0188] In this embodiment, the vehicle body includes a roof. The power interface device can be located near the front reading lights, next to the sunroof control area, or near the rear air conditioning vents. At this location, the sealing cover 100 is embedded in the roof interior panel. Since the installation direction is from top to bottom (from outside the vehicle to inside), an "inverted" installation method is typically required. The mounting bracket 300 is positioned above the roof sheet metal or crossbeam, and utilizes its inverted positioning part 1200 or inverted mounting part 1300 to cooperate with the second support plate of the roof (such as a roof crossbeam) to overcome gravity and achieve pre-positioning and auxiliary support.

[0189] In another embodiment, the vehicle body includes a dashboard, and a power interface device is disposed on the dashboard.

[0190] In this embodiment, the power interface device can also be located on the instrument panel, such as below the driver's side, in front of the passenger side, or in the center of the dashboard. Its installation logic is similar to that of the center console embodiment, which is a typical "formal" application.

[0191] In another embodiment, the vehicle body includes an armrest box, and a power interface device is disposed on the armrest box.

[0192] In this embodiment, the power interface device can be located on the front or rear wall of the front center armrest box, or inside the box. This provides a convenient charging location for both front and rear passengers.

[0193] In another embodiment, the vehicle body includes a seat, and a power interface device is disposed on the seat.

[0194] In this embodiment, the power interface device can also be integrated into the vehicle seat, for example, it can be located on the side of the backrest of the front seat for the convenience of rear passengers; or it can be located in the side panel of the seat.

[0195] In another embodiment, the vehicle body includes body pillars, and the power interface device is located on the trim panel of the body pillars.

[0196] In this embodiment, as a common and practical arrangement, the power interface device can be installed on the trim panel of the vehicle body pillars (such as the A-pillar, B-pillar, or C-pillar). This is particularly suitable for providing convenience for rear passengers and keeping the cables inside the vehicle tidy. When installing in this location, the shape of the sealing cover 100 needs to be adapted to the curvature and internal space of the pillar trim panel.

[0197] In another embodiment, the vehicle body includes a luggage compartment, and a power interface device is located on the luggage compartment.

[0198] In this embodiment, in order to meet the power needs of vehicle electrical appliances (such as air pumps, vehicle refrigerators, and emergency power supplies), the power interface device can be installed on the trim panel near the side wall, front wall, or floor of the trunk.

[0199] In another embodiment, the vehicle body includes doors, and a power interface device is located on the door trim panel.

[0200] In this embodiment, the power interface device can also be integrated into the door trim panel, for example, located near the door handle or at the front of the storage compartment, to provide the driver and passengers with the nearest power access point.

[0201] In some embodiments, reference is made to Figure 16 and Figure 17 As shown, the connector includes a connector body 610, a first conductive contact 620, and at least one second conductive contact 630. The first conductive contact 620 is disposed on the end face of the connector body 610 facing the power interface device. The first conductive contact 620 is used to abut against the corresponding conductive spring in the power interface device to achieve electrical connection.

[0202] The second conductive contact 630 is provided on the side wall of the connector body 610 and is used to abut against the corresponding conductive spring in the power interface device to achieve electrical connection.

[0203] The connector 600 provided in this application embodiment is used in conjunction with a power interface device in a vehicle to provide power or data transmission for in-vehicle electrical equipment. The connector 600 mainly includes a connector body 610, a first conductive contact 620, and at least one second conductive contact 630.

[0204] The connector body 610 is generally cylindrical or block-shaped, with its front end serving as an insertion end for insertion into the socket of the power interface device. A first conductive contact 620 is provided on the end of the connector body 610 facing the power interface device, i.e., the insertion end. The first conductive contact 620 can be a circular contact, an annular conductive surface, or other shaped conductive structure, used to axially abut against the corresponding conductive spring in the power interface device after the connector 600 is inserted into place, forming a first set of electrical connection paths.

[0205] At least one second conductive contact 630 is provided on the side wall of the connector body 610. The second conductive contact 630 can be an elastic contact, an annular conductive strip, or a raised conductive sheet, etc., and is used to elastically abut against the corresponding conductive spring in the power interface device radially during the insertion of the connector 600, forming a second set of electrical connection paths. The number of second conductive contacts 630 can be set according to actual needs, for example, two can be set to correspond to the positive and negative terminals of the power supply, respectively.

[0206] When the connector 600 is inserted into the power interface device, the first conductive contact 620 forms axial contact with the corresponding conductive spring at the end face, and the second conductive contact 630 forms radial contact with the corresponding conductive spring at the side wall. Both sets of contact paths are simultaneously conductive, allowing current or signals to be transmitted through multiple contact interfaces, thereby effectively expanding the conductive contact area without significantly increasing the overall size of the connector 600.

[0207] Optionally, the first conductive contact 620 and the second conductive contact 630 may be made of conductive materials such as copper alloy, and the surface may be plated with gold or silver to improve conductivity and corrosion resistance. The connector body 610 may be made of insulating material to isolate the electrical paths between the conductive contacts.

[0208] The connector 600 of this application extends the conductive contact area from a single surface to multiple surfaces by providing a first conductive contact portion 620 and a second conductive contact portion 630 on the end face and side wall of the connector body 610, respectively, effectively increasing the conductive contact area. In high-current transmission scenarios, a larger contact area means lower contact resistance and more uniform current distribution, thereby enabling it to carry a larger current. This solves the technical problem that the current-carrying capacity of existing connectors is limited due to the contact interface layout being restricted to a single surface.

[0209] Furthermore, due to the increased conductive contact area, the contact resistance is significantly reduced. According to Joule's law, the reduction in contact resistance directly reduces the heat generated when current flows, effectively controlling the operating temperature rise of the connector 600 under high current conditions. This not only improves electrical safety but also slows down the oxidation and aging rate of the contact parts, extending the service life of the connector 600.

[0210] Traditional solutions often require increasing the overall size of the connector to expand the contact area of ​​a single surface in order to improve current carrying capacity. However, this application achieves improved current carrying capacity by utilizing both the end face and the side wall, without significantly increasing the volume of the connector by 600, perfectly aligning with the development trend of miniaturization and lightweighting of vehicle-mounted equipment.

[0211] The end face contact and side wall contact form a multi-dimensional electrical connection path. Even if the contact in one direction fluctuates briefly due to vibration or insertion and removal wear, the contact in the other direction can still maintain conductivity, thereby improving the redundancy and reliability of the overall electrical connection.

[0212] In another embodiment, reference Figure 16 and Figure 17 As shown, the first conductive contact 620 is located at the center of the end face of the connector body 610 facing the power interface device.

[0213] In this embodiment, the first conductive contact 620 is located at the center of the end face of the connector body 610 facing the power interface device. That is, the first conductive contact 620 is located at the geometric center of the insertion end face of the connector body 610, rather than being eccentrically arranged.

[0214] By positioning the first conductive contact 620 at the center of the end face, the connector 600 is always positioned on the axis of the connector body 610 when it is inserted into the power interface device. Once the connector 600 is fully inserted, the conductive spring in the power interface device corresponding to the first conductive contact 620 can axially abut against it from the front, transmitting the contact force along the axial direction without generating a deflection torque.

[0215] The first conductive contact 620 can be in the form of a center contact or a center conductive pad. For example, in one example, the first conductive contact 620 is a hemispherical contact protruding from the center of the end face, with a diameter of 2 mm to 5 mm, for point contact with the center spring in the power interface device. In another example, the first conductive contact 620 is a circular conductive pad embedded in the center of the end face, with its surface flush with or slightly protruding from the end face, for surface contact with the center spring in the power interface device. In another embodiment, the first conductive contact 620 can be in the form of a pin.

[0216] A positioning groove or positioning hole may be provided at the center of the end face of the connector body 610 to accommodate and fix the first conductive contact 620, ensuring that it does not shift during long-term use. The first conductive contact 620 and the connector body 610 may be fixed by injection molding, pressing, or bonding.

[0217] In this embodiment, the first conductive contact 620 is disposed at the center of the end face, so that it is always located on the axis of the connector body 610. When the connector 600 is inserted into the power interface device, the position of the first conductive contact 620 remains unchanged regardless of whether there is a slight rotational deviation of the connector 600, thereby ensuring precise alignment with the corresponding conductive spring in the power interface device and avoiding poor contact or misalignment caused by eccentricity.

[0218] Since the first conductive contact 620 is located at the center of the end face, the axial abutment force between it and the conductive spring acts on the central axis of the connector body 610, and will not generate a torque that causes the connector 600 to deflect. This makes the connector 600 subject to balanced force during insertion, less prone to jamming or tilting, and improves the smoothness of the insertion and removal operation.

[0219] By placing the first conductive contact 620 at the center of the end face, the central area of ​​the end face can be fully utilized, while the side wall area is reserved for the second conductive contact 630. This concentric layout allows for a reasonable allocation of the internal space of the connector 600, which is conducive to arranging more conductive contact structures in a limited space. This further enhances the current carrying capacity without increasing the overall size of the connector 600, which is in line with the trend of device miniaturization proposed in the background art.

[0220] In other embodiments, refer to Figure 16 and Figure 17 As shown, there are multiple second conductive contact portions 630, and each second conductive contact portion 630 is distributed at different positions along the insertion direction of the connector body 610.

[0221] In this embodiment, there are multiple second conductive contacts 630, and each second conductive contact 630 is distributed at a different position along the insertion direction of the connector body 610. That is, the multiple second conductive contacts 630 are not concentrated at the same axial position on the side wall of the connector body 610, but are arranged sequentially along the axial direction to form a stepped or sequential contact layout.

[0222] For example, in one example, there are two second conductive contacts 630, namely a first sidewall contact and a second sidewall contact. The first sidewall contact is close to the insertion tip of the connector body 610, and the second sidewall contact is located behind the first sidewall contact, with a certain distance, for example, 2 mm to 5 mm, between them along the axial direction. In another example, there are three or more second conductive contacts 630, which are uniformly or non-uniformly distributed along the axial direction.

[0223] Each second conductive contact 630 can be in the form of annular conductive strips, encircling the side wall of the connector body 610 to form annular contact areas. Alternatively, it can be in the form of partial contacts or arc-shaped conductive sheets, arranged at intervals along the circumference. When annular conductive strips are used, insulating isolation grooves are provided between adjacent annular conductive strips to prevent mutual short circuits.

[0224] Accordingly, the power interface device is provided with conductive springs that correspond one-to-one with each of the second conductive contacts 630. Each conductive spring is located at a different height along the insertion direction so that it can elastically abut against the corresponding second conductive contact 630 when the plug 600 is inserted into place.

[0225] Optionally, the width (axial dimension) of each second conductive contact 630 can be the same, or it can be designed differently according to the magnitude of the current it carries. For example, the width of the second conductive contact 630 near the insertion front end carries a larger current, and its width can be appropriately increased; the width of the second conductive contact 630 near the rear end carries a smaller current or signal, and its width can be appropriately reduced.

[0226] In this embodiment, by providing multiple second conductive contacts 630 and distributing them axially at different positions, the conductive contact area on the sidewall of the connector 600 is effectively increased. Compared to a single sidewall contact, multiple contacts form multiple parallel conductive paths, allowing current to be transmitted through more contact interfaces. This significantly reduces the overall contact resistance, improves the current-carrying capacity of the connector 600, and better solves the technical problem of insufficient current-carrying capacity mentioned in the background art.

[0227] Multiple second conductive contacts 630 are distributed axially, so that during insertion, each contact of the connector 600 contacts the conductive spring in the power interface device sequentially, rather than simultaneously. This hierarchical contact mechanism distributes the total insertion force across different insertion stages, effectively reducing peak insertion force and improving the user's insertion and removal experience.

[0228] In a vehicle vibration environment, multiple axially distributed contact points provide multi-point constraints to the connector 600, similar to a multi-support structure. Compared to a single contact, the multi-point distribution provides more stable positioning in both the axial and radial directions, effectively resisting axial movement and radial sway of the connector 600, and further improving the reliability of the electrical connection.

[0229] Multiple second conductive contacts 630 can each perform different functions, such as transmitting the positive power supply, transmitting the negative power supply, and transmitting data signals. This flexible division of labor allows the connector 600 to adapt to different types and specifications of power interface devices, improving the product's versatility and applicability.

[0230] In some possible embodiments, refer to Figure 16 and Figure 17 As shown, each second conductive contact 630 is an annular conductive strip surrounding the side wall of the connector body 610.

[0231] In this embodiment, each second conductive contact 630 is an annular conductive strip surrounding the sidewall of the connector body 610. That is, each second conductive contact 630 has a complete annular strip structure, encircling the connector body 610 circumferentially to form a continuous conductive ring surface. The width (axial dimension) of the annular conductive strip can be designed according to the current carrying requirements, for example, set to 1mm to 5mm.

[0232] The annular conductive strip can be made of metallic conductive materials, such as copper alloys or stainless steel, and its surface can be plated with gold, silver, or nickel to improve conductivity and corrosion resistance. The annular conductive strip can be fixed to the side wall of the connector body 610 by methods such as injection molding, press-fitting, laser welding, or bonding. When using the injection molding process, the annular conductive strip is embedded during the molding of the connector body 610, forming an integrated structure with high bonding strength and sealing performance.

[0233] When there are multiple second conductive contacts 630, each annular conductive strip is arranged sequentially along the axial direction of the connector body 610, and an insulating isolation groove is provided between adjacent annular conductive strips. The insulating isolation groove can be an annular groove on the surface of the connector body 610, or it can be an insulating material layer filled between adjacent annular conductive strips to prevent short circuits between adjacent conductive strips.

[0234] Accordingly, the power interface device is provided with conductive springs corresponding to each annular conductive strip. Each conductive spring is located at a different height along the insertion direction, and the contact portion of each conductive spring has an arc-shaped surface or contact protrusion that matches the annular conductive strip, so as to form a reliable elastic abutment with the annular conductive strip when the connector 600 is inserted into place. Since the annular conductive strip extends continuously in the circumferential direction, the annular conductive strip can maintain contact with the corresponding conductive spring regardless of whether the connector 600 rotates during insertion.

[0235] In this embodiment, the annular conductive strip surrounds the side wall of the connector body 610, ensuring reliable contact between the conductive spring in the power interface device and the connector 600 regardless of the circumferential angle from which they engage. This design eliminates the sensitivity of traditional point or localized contacts to the insertion angle of the connector 600, ensuring the reliability of the electrical connection even if the connector 600 rotates during insertion.

[0236] Furthermore, the annular conductive strip extends continuously along the circumference, and the contact area between it and the conductive spring is an annular strip-shaped region, with an effective contact area much larger than that of point or local contact points. A larger contact area means lower contact resistance and more uniform current distribution, thereby enabling it to carry a larger current and better solving the technical problem of "insufficient current carrying capacity" mentioned in the background technology.

[0237] In a vehicle vibration environment, the annular contact area between the annular conductive strip and the conductive spring has good anti-disturbance capability. Even if the connector 600 experiences slight radial displacement or axial movement, a portion of the annular conductive strip will always remain in contact with the conductive spring, making instantaneous disconnection less likely, thereby improving the stability and reliability of the electrical connection.

[0238] In some embodiments, reference is made to Figure 16 and Figure 17 As shown, the diameter of each second conductive contact 630 decreases sequentially along the insertion direction of the connector body 610.

[0239] In this embodiment, the diameter of each second conductive contact 630 decreases sequentially along the insertion direction of the connector body 610. That is, from the insertion front end to the rear end of the connector body 610, the outer diameter of each second conductive contact 630 decreases in a step-like manner. For example, when there are three second conductive contacts 630, the first second conductive contact 630 near the insertion front end has the largest diameter, the middle second conductive contact 630 has the second largest diameter, and the third second conductive contact 630 near the rear end has the smallest diameter.

[0240] Each second conductive contact 630 is an annular conductive strip surrounding the sidewall of the connector body 610. The diameter of this strip can be varied by changing the outer diameter of the connector body 610 at the location of the annular conductive strip, or by adjusting the thickness of the annular conductive strip itself. For example, the outer diameter of the connector body 610 decreases in a stepped manner along the insertion direction, and each annular conductive strip is fitted onto the corresponding step, so that the outer diameter of each annular conductive strip decreases synchronously with the outer diameter of the connector body 610.

[0241] Accordingly, the inner wall of the socket of the power interface device may be provided with a stepped inner wall that matches the diameter of each second conductive contact 630, or it may be provided with corresponding conductive springs. Each conductive spring is located at a different height along the insertion direction, and its contact portion forms an elastic abutment with the annular conductive strip of the corresponding diameter. Since the diameters of each second conductive contact 630 are different, during the insertion process of the connector 600, the second conductive contact 630 with the largest diameter contacts the corresponding conductive spring first, and then the second conductive contacts 630 with smaller diameters contact in sequence, forming a gradual contact process.

[0242] Optionally, the diameter difference between adjacent second conductive contacts 630 can be equal or unequal. For example, the diameter difference near the front end is larger to form a distinct guide segment, while the diameter difference near the rear end is smaller to provide fine positioning.

[0243] In this embodiment, since the diameters of the second conductive contacts 630 decrease sequentially along the insertion direction, during the insertion process, the contact with the largest diameter contacts first contacts the conductive spring in the power interface device, followed by the smaller diameter contacts in sequence. This progressive contact mechanism distributes the total insertion force across different insertion stages, avoiding the instantaneous insertion force peak caused by all contacts contacting simultaneously, significantly improving the smoothness of the insertion and removal operation and the user experience.

[0244] The larger-diameter second conductive contact 630 at the front end contacts the inner wall of the socket or conductive spring of the power interface device during the initial insertion, acting as a pre-guide to guide the connector 600 to penetrate along the correct axis. As the insertion depth increases, the smaller-diameter second conductive contact 630 gradually participates in positioning, ultimately achieving precise alignment. This self-guiding function effectively reduces the risk of poor contact caused by misalignment.

[0245] Within the limited axial length of the connector body 610, multiple annular conductive strips are arranged in decreasing diameter order. This allows for the provision of as many conductive contacts as possible without significantly increasing the overall size of the connector 600. Larger diameter annular conductive strips provide a larger conductive contact area, suitable for carrying high currents; smaller diameter annular conductive strips can be used for signal transmission or auxiliary grounding. This differentiated design enables the connector 600 to achieve higher current-carrying capacity within a compact structure, better addressing the technical problem of insufficient current-carrying capacity mentioned in the prior art.

[0246] In other embodiments, refer to Figure 16 and Figure 17 As shown, the end face of the connector body 610 facing the power interface device has a groove, and the first conductive contact part 620 is disposed in the groove.

[0247] In this embodiment, the end face of the connector body 610 facing the power interface device is provided with a groove, and the first conductive contact 620 is disposed in the groove. The groove is formed on the end face of the insertion end of the connector body 610, and its opening faces the side of the power interface device, that is, towards the insertion direction. The shape of the groove can be circular, square or polygonal, and its depth is determined according to the thickness of the first conductive contact 620 and the protection requirements, for example, 0.5mm to 3mm.

[0248] The first conductive contact 620 is disposed inside the groove, and can be located at the bottom center of the groove or at other positions on the bottom of the groove. The upper surface of the first conductive contact 620 can be lower than the opening end face of the groove, flush with the opening end face of the groove, or slightly protruding from the opening end face of the groove, as long as it can reliably abut with the corresponding conductive spring in the power interface device.

[0249] The groove design protects the first conductive contact 620 from direct contact or scratches by external objects when it is not inserted. Simultaneously, during the insertion of the connector 600 into the power interface device, the opening edge of the groove acts as a preliminary guide, directing the corresponding conductive spring in the power interface device to accurately enter the groove and contact the first conductive contact 620.

[0250] Optionally, the inner wall of the groove can be configured as an inclined guide slope to further guide the conductive spring into the bottom of the groove smoothly. A positioning protrusion or positioning groove can also be provided at the bottom of the groove to accurately position the first conductive contact 620 and prevent it from shifting during long-term use.

[0251] In this embodiment, the first conductive contact 620 is disposed within the groove, so that it is surrounded and protected by the sidewalls of the groove when not inserted. This effectively prevents damage or deformation of the surface of the first conductive contact 620 due to accidental collisions or scratches during transportation, storage, or daily use. This is crucial for maintaining the surface smoothness and conductivity of the first conductive contact 620, which helps maintain low contact resistance and thus indirectly ensures the current-carrying capacity of the connector 600.

[0252] The opening edge of the groove guides the connector 600 when it is inserted into the power interface device, allowing the corresponding conductive spring in the power interface device to slide smoothly along the inner wall of the groove and accurately align with the first conductive contact 620. This guiding function reduces the risk of poor contact due to misalignment and improves the reliability of the electrical connection.

[0253] The shape and size of the groove can be matched with the corresponding conductive spring or guide structure in the power interface device. Only the correctly oriented plug 600 can be smoothly inserted and the conductive spring can enter the groove, thereby preventing misinsertion and avoiding the risk of circuit damage caused by reverse insertion.

[0254] In another embodiment, reference Figure 16 and Figure 17 As shown, the first conductive contact portion 620 is lower than or flush with the opening end face of the groove.

[0255] In this embodiment, the first conductive contact portion 620 is lower than or flush with the opening end face of the groove. That is, the upper surface of the first conductive contact portion 620 is not higher than the opening edge of the groove, but is located inside the groove at a lower position or flush with the opening edge.

[0256] When the first conductive contact 620 is lower than the opening end face of the groove, the first conductive contact 620 is completely contained inside the groove, and its top surface is lower than the end face of the connector body 610. At this time, the sidewall of the groove forms a protective barrier, enclosing the first conductive contact 620 and preventing it from directly contacting external objects when not inserted.

[0257] When the first conductive contact 620 is flush with the opening end face of the groove, the upper surface of the first conductive contact 620 is on the same plane as the end face of the connector body 610. At this time, although the first conductive contact 620 does not protrude from the end face, its surface can still make contact with the corresponding conductive spring in the power interface device through the groove opening.

[0258] To achieve the aforementioned height position, the thickness of the first conductive contact 620 or the depth of the groove can be adjusted. For example, when the groove depth is 1 mm and the thickness of the first conductive contact 620 is 0.6 mm, the upper surface of the first conductive contact 620 is 0.4 mm lower than the opening end face of the groove; when the groove depth is equal to the thickness of the first conductive contact 620, the two are flush.

[0259] Optionally, the first conductive contact 620 can be fixed to the bottom of the groove by means of embedding, pasting or welding, and its fixed height can be finely adjusted by a shim or positioning structure.

[0260] In this embodiment, the first conductive contact 620 is configured to be lower than or flush with the opening end face of the groove, so that it is completely or partially hidden inside the groove when not inserted. This concealed design effectively avoids surface damage, deformation, or contamination of the first conductive contact 620 due to accidental collisions, scratches, or finger touches during transportation, storage, or daily use. It helps to maintain the surface smoothness and conductivity of the first conductive contact 620 over a long period of time, thereby maintaining low contact resistance and indirectly ensuring the current carrying capacity of the connector 600.

[0261] The first conductive contact 620 does not protrude from the end face of the connector body 610, reducing the risk of users accidentally contacting live parts during plugging and unplugging. Especially in live plugging and unplugging scenarios, it helps prevent electric shock accidents and improves the safety of product use.

[0262] The first conductive contact 620 does not protrude from the end face of the groove opening, so that when the connector 600 is inserted into the power interface device, the end face will not experience additional resistance or jamming due to the protruding contact. The conductive spring in the power interface device can smoothly enter the groove and contact the first conductive contact 620, improving the smoothness of the insertion and removal operation.

[0263] In other possible embodiments, refer to Figure 16 and Figure 17 As shown, the third external thread 640 and each of the second conductive contacts 630 are arranged sequentially along the axial direction of the connector body 610, and each of the second conductive contacts 630 is closer to the insertion front end of the connector body 610 than the third external thread 640.

[0264] In this embodiment, the third external thread 640 and each of the second conductive contacts 630 are arranged sequentially along the axial direction of the connector body 610, and each of the second conductive contacts 630 is closer to the insertion front end of the connector body 610 than the third external thread 640. That is, from the insertion front end to the rear end of the connector body 610, the second conductive contacts 630 are arranged first, and then the third external thread 640 is arranged. The two are arranged sequentially along the axial direction without overlapping.

[0265] For example, in one embodiment, two second conductive contacts 630 are provided near the insertion tip of the connector body 610, namely a first annular conductive strip and a second annular conductive strip, which are arranged axially spaced apart. Behind the second annular conductive strip, closer to the tail of the connector body 610, a third external thread 640 is provided. An insulating isolation section with a certain distance may be provided between the third external thread 640 and the nearest second conductive contact 630 to avoid electrical interference between the thread structure and the conductive contact.

[0266] The axial spacing between each second conductive contact 630 and the third external thread 640 can be designed according to actual needs, such as 2mm to 10mm, to ensure that the normal working position of the conductive contact is not affected when the thread is engaged. A guide section or transition section can be provided between the starting end of the third external thread 640 and the rear end of the last second conductive contact 630 to guide the insertion of the connector 600 smoothly.

[0267] In another possible embodiment, there are two second conductive contacts 630, which are used for electrical connection with a power source, and the first conductive contact 620 is used for electrical connection with a signal.

[0268] In this embodiment, the two second conductive contacts 630 correspond to the positive and negative terminals of the power supply, respectively, and are used to provide power transmission for high-power vehicle-mounted electrical equipment. The two second conductive contacts 630 are arranged sequentially along the axial direction of the connector body 610, or spaced apart circumferentially, with sufficient electrical clearance between them, and are isolated from each other by the insulating material of the connector body 610 to prevent short circuits.

[0269] The first conductive contact 620 is located on the end face of the connector body 610 facing the power interface device, and is used to abut against the corresponding signal spring in the power interface device to realize the transmission of data signals or control signals. The first conductive contact 620 can be in the form of a center contact, a center conductive disk, or a center conductive pin, etc., and its size is usually smaller than that of the second conductive contact 630 to meet the requirements of low capacitance and low inductance for signal transmission.

[0270] In one example, both second conductive contacts 630 are annular conductive strips surrounding the sidewall of the connector body 610, serving as the contact interfaces for the positive and negative power supplies, respectively. The first conductive contact 620 is a hemispherical contact located at the center of the end face of the connector body 610, serving as the contact interface for signal transmission. When the connector 600 is inserted into the power interface device, the two second conductive contacts 630 elastically abut against the corresponding power springs in the power interface device, forming a power circuit; simultaneously, the first conductive contact 620 axially abuts against the corresponding signal springs in the power interface device, forming a signal path. Power transmission and signal transmission are completed independently through different conductive contacts, without interference.

[0271] Optionally, the diameters of the two second conductive contacts 630 can be the same or different to distinguish the insertion direction of the positive and negative electrodes, thus preventing mistaken insertion. The surface of the first conductive contact 620 can be plated with gold or silver to improve the reliability of signal transmission and corrosion resistance.

[0272] In this embodiment, the power transmission function is assigned to the two second conductive contacts 630, and the signal transmission function is assigned to the first conductive contact 620, thus achieving physical isolation between the power circuit and the signal circuit. This functional separation design effectively avoids ripple noise and high-current transient interference on the power line from coupling to the signal line, ensuring the integrity and purity of the data signal or control signal. It is particularly suitable for scenarios that require simultaneous high-power charging and high-speed data transmission.

[0273] The two second conductive contacts 630 are specifically designed for power transmission and can be optimized for high current requirements. For example, the width of the annular conductive strip can be increased, high-conductivity materials can be used, or the contact area can be increased to maximize the current-carrying capacity of the power circuit without affecting signal transmission. This specialized division of labor allows the connector 600 to simultaneously meet the dual requirements of high-power supply and high-quality signal transmission within a compact size, better addressing the technical problem of insufficient current-carrying capacity mentioned in the background art.

[0274] The power supply circuit and signal circuit are physically separated, reducing the possibility of common impedance coupling and electromagnetic interference. Meanwhile, the first conductive contact 620 is located at the center of the end face, away from the power supply contact on the side wall, further reducing the impact of power supply noise on the signal and improving the overall system's electromagnetic compatibility.

[0275] The two second conductive contacts 630 are used for power supply and the first conductive contact 620 is used for signal, which clearly defines the functions of the connector 600. This allows the connector 600 to be compatible with standard power and signal interface specifications, improving the product's versatility and interchangeability, and facilitating its application in different vehicle models and equipment.

[0276] In another possible embodiment, it further includes a first conductive lead and at least one second conductive lead, both of which are disposed within the connector body 610; one end of the first conductive lead is electrically connected to the first conductive contact 620, and the other end is used for electrical connection to an external circuit; one end of each second conductive lead is electrically connected to the corresponding second conductive contact 630, and the other end is used for electrical connection to an external circuit.

[0277] In this embodiment, the connector 600 further includes a first conductive lead and at least one second conductive lead. The first conductive lead and each of the second conductive leads are disposed inside the connector body 610, for example, by injection molding, embedding, or passing through through holes inside the connector body 610.

[0278] One end of the first conductive lead is electrically connected to the first conductive contact 620, and the other end is used for electrical connection to an external circuit. The first conductive lead can be in the form of a metal wire, a conductive sheet, or a flexible circuit board, and its material is usually copper or a copper alloy. The surface can be tin-plated or silver-plated to improve conductivity and solderability. The connection between the first conductive lead and the first conductive contact 620 can be achieved by welding, crimping, or integral molding.

[0279] One end of each second conductive lead is electrically connected to the corresponding second conductive contact 630, and the other end is used for electrical connection to an external circuit. The number of second conductive leads corresponds to the number of second conductive contacts 630. For example, when there are two second conductive contacts 630, there are also two second conductive leads, each electrically connected to one of the two second conductive contacts 630. The second conductive leads are mutually insulated, either by the insulating material of the connector body 610 or by each being fitted with an insulating sleeve.

[0280] The other ends of the first conductive lead and each of the second conductive leads can converge at the tail of the connector body 610 to form a unified lead-out port for connection with external wiring harnesses or circuit boards. The lead-out port can adopt a standardized connector interface, such as pins, pads, or pins, to facilitate quick docking with vehicle wiring harnesses.

[0281] Optionally, the first conductive lead and each of the second conductive leads may be provided with a certain redundant length or bending section inside the connector body 610 to absorb the stress caused by thermal expansion and contraction or vibration and prevent the lead from breaking.

[0282] In this embodiment, the first conductive contact 620 and the second conductive contact 630 are electrically connected to the external circuit via the first conductive lead and the second conductive lead, forming a complete current transmission path. The conductive leads are made of low-resistance material and have a sufficient cross-sectional area, enabling them to carry large currents without generating significant heat accumulation. This ensures the current-carrying capacity of the connector 600 in high-power transmission scenarios and better solves the technical problem of insufficient current-carrying capacity mentioned in the background art.

[0283] Integrating the conductive leads inside the connector body 610 avoids the messy routing of exposed wires on the outside, making the connector 600 look cleaner and reducing interference from external wiring harnesses on the plugging operation, thus reducing the risk of poor contact caused by wiring harness pulling.

[0284] The first and second conductive leads are isolated from each other inside the connector body 610, reducing electromagnetic coupling between the power supply circuit and the signal circuit, which helps maintain the purity of signal transmission. At the same time, the built-in conductive leads are shielded and protected by the connector body 610, reducing the intrusion of external electromagnetic interference.

[0285] The conductive leads are pre-embedded inside the connector body 610, making the connector 600 a complete modular component. During the production process, independent continuity and insulation tests can be performed on the connection between the conductive leads and the conductive contacts to ensure that the electrical performance of each connector 600 is qualified before final assembly, thereby improving the consistency and reliability of product quality.

[0286] It should be noted that the conductive part 400 includes a plurality of conductive springs, each conductive spring including a connecting section fixed to the mounting base 300 and two opposing abutting sections extending from the connecting section toward the interior trim 10. A clamping space is formed between the two abutting sections for elastically clamping the corresponding contacts of the plug-in 600. A contact portion for contacting the plug-in 600 is formed on each abutting section, and the contact portion is located within the clamping space.

[0287] In this embodiment, reference is made to... Figure 8 , Figure 12 , Figure 13 and Figure 14As shown, the conductive spring can be a first conductive spring 410, a second conductive spring 420, or a third conductive spring 430. The connecting segment of the conductive spring can refer to the first connecting segment 412 of the first conductive spring 410, the second connecting segment 422 of the second conductive spring 420, or the third connecting segment 432 of the third conductive spring 430. The abutting segment of the conductive spring can refer to the first abutting segment 411 of the first conductive spring 410, the second abutting segment 421 of the second conductive spring 420, or the third abutting segment 431 of the third conductive spring 430. The contact portion formed on the abutting segment can refer to the first contact portion 4111 of the first conductive spring 410, the second contact portion 4211 of the second conductive spring 420, or the third contact portion 4311 of the third conductive spring 430.

[0288] The conductive part 400 includes multiple conductive springs, which are typically made of a metallic material (such as a copper alloy) with good conductivity and elasticity. Each conductive spring specifically includes:

[0289] Connection section: This connection section is fixed to the mounting base 300, for example, by riveting, welding, or screw fastening. The connection section serves to provide support and electrical conduction, and one end of it is electrically connected to the power supply circuit.

[0290] Two opposing abutment sections: These two abutment sections extend from one end of the connecting section toward the interior trim 10 (i.e., toward the user operating space side, so as to contact the connector 600 passing through the through hole of the interior trim 10). The two abutment sections are arranged opposite each other, forming a clamping space between them. The width of this clamping space is slightly less than the thickness of the corresponding contact on the mating connector 600.

[0291] Contact portion: On the inner surface of each abutment segment facing the clamping space, a contact portion is formed, such as a hemispherical, ridge-like, or dot-like protrusion. These two contact portions are arranged opposite each other and are located together within the clamping space.

[0292] When the connector 600 is inserted from the user-facing side of the interior trim 10 and passes through the through-hole into the clamping space, its corresponding contacts first press against the contact portions on the two abutment sections. Due to the elasticity of the abutment sections, they are pushed outwards, generating an elastic restoring force pointing inwards into the clamping space. This elastic restoring force causes the two contact portions to press tightly against the two sides of the connector 600 contacts, forming a multi-point, highly reliable electrical contact. Simultaneously, the localized protrusions in the contact portions can pierce any oxide film or dirt that may be present, further ensuring a low-resistance connection.

[0293] Optionally, the number of conductive springs can be adjusted according to the required current or the number of signal channels. For example, three conductive springs can be configured, namely the first conductive spring 410, the second conductive spring 420, and the third conductive spring 430, corresponding to the positive, negative, and signal terminals, respectively. The contact length and angle of each conductive spring can be optimized according to the actual required clamping force and insertion stroke.

[0294] It should be noted that the conductive part 400 can be two conductive springs, three conductive springs, four conductive springs, five conductive springs, etc.

[0295] The power interface device of this application embodiment forms an elastic clamping structure by providing two opposing abutment sections and their inner contact portions. When the connector 600 is inserted, the two abutment sections undergo symmetrical elastic deformation, thereby applying a balanced and continuous clamping force on both sides of the connector 600 contact. This bidirectional elastic clamping mechanism effectively overcomes the problem of unidirectional contact force attenuation caused by vibration, impact, or temperature changes during vehicle operation, significantly reducing the risk of accidental disengagement between the conductive spring and the connector 600 contact, thus solving the technical problem of poor contact stability between the conductive terminal and the connector contact in related technologies.

[0296] The contact area can generate high contact pressure over a small contact area, which is beneficial for breaking down the surface oxide layer and forming a reliable metal-metal contact, thereby effectively reducing contact resistance. Reduced contact resistance means less Joule heat is generated under the same current, improving the electrical safety and long-term service life of the power interface device.

[0297] In another embodiment, the contact portions of each conductive spring are located at different heights along the insertion direction of the connector 600, so that when the connector 600 is inserted into place, they respectively correspond to the contacts on the connector 600 located at different positions along its own direction.

[0298] In this embodiment, the contact portions of each conductive spring are located at different heights along the insertion direction of the connector 600. That is, for the multiple conductive springs disposed on the mounting base 300, their respective contact portions are not at the same horizontal position in a plane perpendicular to the insertion direction, but are arranged staggered along the insertion direction.

[0299] For example, in one embodiment, the conductive part 400 includes three conductive springs: a first conductive spring 410, a second conductive spring 420, and a third conductive spring 430. The first conductive spring 410 and the second conductive spring 420 are used to connect to a power source, and the third conductive spring 430 is used to connect to a signal source. The first contact portion 4111 of the first conductive spring 410 is used to abut against a first electrical connection area on the side wall of the connector 600, the second contact portion 4211 of the second conductive spring 420 is used to abut against a second electrical connection area on the side wall of the connector 600, and the third contact portion 4311 of the third conductive spring 430 is used to abut against a third electrical connection area at the center of the connector 600.

[0300] When the connector 600 is fully inserted, the contact portion of each conductive spring forms an independent and non-interfering electrical connection with its corresponding contact point.

[0301] It should be noted that the first electrical connection area on the side wall of the connector 600 can abut against one of the second conductive contacts 630 of the connector 600, the second electrical connection area on the side wall of the connector 600 can be another second conductive contact 630 of the connector 600, and the third electrical connection area on the side wall of the connector 600 can be the first conductive contact 620 of the connector 600.

[0302] Optionally, the height difference of the contact portion of each conductive spring can be precisely set according to the spacing of the contacts on the connector 600, generally ranging from 0.5mm to 3mm, to adapt to different connector standards.

[0303] In this embodiment, by setting the contact portions of each conductive spring at different heights along the insertion direction, each contact portion only contacts the corresponding axial contact on the connector 600, thereby achieving independent transmission of multiple power supplies and signals. This staggered layout effectively avoids short circuits or signal crosstalk caused by overlapping contact portions between different contacts, and is particularly suitable for high-frequency application scenarios that require simultaneous transmission of power and data.

[0304] The contact parts at different heights correspond one-to-one with the contacts at different positions on the connector 600, which is equivalent to building a physical coding mechanism. If the connector 600 is inserted in the wrong direction or with the wrong model, its contact position will not match the height of the contact part, resulting in failure to insert properly or failure to form a complete electrical connection. This serves as a foolproof mechanism and avoids the risk of circuit damage caused by misinsertion.

[0305] In other embodiments, unlike the aforementioned embodiments, this embodiment sets the position of the contact portion of each conductive spring in the insertion direction differently.

[0306] Specifically, the contact portions of each conductive spring are located at the same height along the insertion direction of the connector 600. In other words, the contact portions of all conductive springs are at the same horizontal position in a plane perpendicular to the insertion direction, meaning they are equidistant from the bottom wall of the mounting cavity 310. The contact portions are arranged circumferentially around the insertion axis of the connector 600, forming a ring array or a fan-shaped distribution.

[0307] For example, when the conductive part 400 includes three conductive springs, the contact portions of the first conductive spring 410, the second conductive spring 420, and the third conductive spring 430 are at the same height in the insertion direction, but are evenly distributed at a certain angle (e.g., 120°) apart in the circumferential direction. Correspondingly, the contact points on the connector 600 corresponding to the three conductive springs are also located in the same axial section, that is, they are spaced apart along the circumferential direction on the outer circumferential surface of the connector 600.

[0308] When the connector 600 is inserted into place, each of its contacts simultaneously contacts the corresponding conductive spring contact portion and forms an elastic clamp. Since all contact portions are at the same height, the connector 600 can complete the docking of all contacts simultaneously without axial movement, thus achieving synchronous electrical connection.

[0309] To achieve this layout, the contact lengths of each conductive spring can be designed to be approximately equal, but their mounting angles or bending directions within the mounting cavity 310 need to be adjusted according to the circumferential distribution. Furthermore, the conductive springs can be isolated from each other by insulating partitions to prevent short circuits from occurring between adjacent springs during elastic deformation.

[0310] In another embodiment, at least one conductive spring sheet has arc-shaped clamping surfaces formed on two opposite abutting sections. The arc-shaped clamping surfaces constitute contact portions, and the two arc-shaped clamping surfaces are spaced apart and facing each other. The two arc-shaped clamping surfaces are used to abut against the two sides of the corresponding contact of the plug 600.

[0311] It should be noted that, in this embodiment, the reference is... Figure 8 , Figure 12 , Figure 13 and Figure 14As shown, the conductive spring can be a first conductive spring 410, a second conductive spring 420, or a third conductive spring 430. The connecting segment of the conductive spring can refer to the first connecting segment 412 of the first conductive spring 410, the second connecting segment 422 of the second conductive spring 420, or the third connecting segment 432 of the third conductive spring 430. The abutting segment of the conductive spring can refer to the first abutting segment 411 of the first conductive spring 410, the second abutting segment 421 of the second conductive spring 420, or the third abutting segment 431 of the third conductive spring 430. The contact portion formed on the abutting segment can refer to the first contact portion 4111 of the first conductive spring 410, the second contact portion 4211 of the second conductive spring 420, or the third contact portion 4311 of the third conductive spring 430.

[0312] In this embodiment, at least one conductive spring sheet has arc-shaped clamping surfaces formed on its two opposing abutting sections. These arc-shaped clamping surfaces are the contact portions, and their shape is a concave arc surface extending into the clamping space. The two arc-shaped clamping surfaces are spaced apart and facing each other, forming a clamping space between them to accommodate the corresponding contacts of the connector 600. When the connector 600 is inserted, both sides of its corresponding contact abut against the two arc-shaped clamping surfaces.

[0313] The radius of curvature of the arc-shaped clamping surface can be optimized according to the external dimensions of the 600 contacts of the connector. For example, for cylindrical contacts or contacts with rounded corners, the radius of curvature of the arc-shaped clamping surface can be set to match the outer diameter of the contact, thereby achieving surface or line contact instead of point contact.

[0314] In a preferred example, the radius of curvature of the arc-shaped clamping surface is slightly larger than the radius of curvature of the contact point, so that two-point contact is formed in the initial insertion stage, and gradually transitions to surface contact as the insertion depth increases, thereby obtaining a larger contact area while ensuring low insertion force.

[0315] Furthermore, the arc-shaped clamping surfaces can have a certain length along the extension direction of the abutment section (i.e., the insertion direction), such as 2mm to 5mm, to provide sufficient sliding guide stroke. The minimum distance between the two arc-shaped clamping surfaces (i.e., the throat width of the clamping space) is slightly less than the thickness of the contact point to ensure elastic clamping force.

[0316] Optionally, all conductive contacts can adopt an arc-shaped clamping surface design, or only the contacts that undertake the main power transmission task (such as the contacts corresponding to the positive and negative terminals of the power supply) can adopt an arc-shaped clamping surface, while the data signal contacts can have a convex contact part to balance cost and performance.

[0317] In this embodiment, the arc-shaped clamping surface and the contact of the plug 600 form an arc-shaped contact, which significantly increases the effective contact area compared to point or ridge-shaped contacts. According to the contact resistance formula, the increased contact area can effectively reduce the contact resistance, thereby reducing Joule heating when current flows and improving the current carrying capacity and thermal safety of the power interface device.

[0318] Furthermore, the arc shape of the curved clamping surface guides the insertion of the connector 600. Even if the connector 600 has a slight angular deviation or offset, the curved surface can automatically guide the contact to the center of the clamping space, achieving self-centering. This not only reduces insertion resistance but also avoids excessive wear or plastic deformation on one side due to misalignment, extending the service life of the conductive spring.

[0319] Furthermore, the contact area between the arc-shaped clamping surface and the contact point is arc-shaped, ensuring that the contact stress is evenly distributed on the arc-shaped surface in a vehicle vibration environment, thus avoiding stress concentration. Compared to point contact, which is prone to fretting wear under vibration, arc-shaped surface contact can better resist the contact separation tendency caused by vibration, thereby further enhancing contact stability.

[0320] The arc-shaped clamping surface is well adaptable to cylindrical, flat, or rounded contacts, enabling reliable electrical connection with different sizes of connectors 600, thus improving the versatility and interchangeability of the power interface device.

[0321] In other embodiments, at least one conductive spring sheet has contact protrusions protruding into the clamping space on two opposite abutting sections. The contact protrusions form contact portions. The two contact protrusions are spaced apart and arranged facing each other. The two contact protrusions are used to abut against the two sides of the corresponding contact of the plug 600.

[0322] It should be noted that, in this embodiment, the reference is... Figure 8 , Figure 12 , Figure 13 and Figure 14 As shown, the conductive spring can be a first conductive spring 410, a second conductive spring 420, or a third conductive spring 430. The connecting segment of the conductive spring can refer to the first connecting segment 412 of the first conductive spring 410, the second connecting segment 422 of the second conductive spring 420, or the third connecting segment 432 of the third conductive spring 430. The abutting segment of the conductive spring can refer to the first abutting segment 411 of the first conductive spring 410, the second abutting segment 421 of the second conductive spring 420, or the third abutting segment 431 of the third conductive spring 430. The contact portion formed on the abutting segment can refer to the first contact portion 4111 of the first conductive spring 410, the second contact portion 4211 of the second conductive spring 420, or the third contact portion 4311 of the third conductive spring 430.

[0323] In this embodiment, at least one conductive spring has contact protrusions protruding into the clamping space on both opposite abutment sections. These contact protrusions constitute contact portions and can be geometrically shaped with obvious protrusion features, such as hemispherical, conical, pyramidal, or truncated cone. The two contact protrusions are spaced apart and facing each other, forming a clamping space between them to accommodate the corresponding contacts of the connector 600. When the connector 600 is inserted, both sides of its corresponding contact abut against the two contact protrusions.

[0324] The height (i.e., protrusion) of the contact protrusions can be optimized according to the required contact pressure and insertion force. In one example, the height of the contact protrusions is 0.2 mm to 0.8 mm, and the radius of curvature at their tips is 0.1 mm to 0.5 mm to ensure sufficiently high contact pressure over a small contact area. The minimum distance between the two contact protrusions is slightly less than the thickness of the 600 contact point of the connector, thereby forcing the abutment section to open elastically during insertion, generating a continuous clamping force.

[0325] Alternatively, the contact protrusion can be integrally formed on the abutment section by means of stamping, etching, or welding, or it can be made separately and fixed to the surface of the abutment section. To ensure good conductivity, the contact protrusion can be made of the same material as the conductive spring (such as copper alloy) or its surface can be plated with gold or silver.

[0326] Unlike the aforementioned arc-shaped clamping surface embodiment, this embodiment employs a raised structure, causing contact to occur within a very small local area, thereby achieving higher contact pressure under the same clamping force. This design is particularly suitable for applications requiring low insertion force and high contact reliability, such as sensitive suppression of minute jitter in high-frequency data signal transmission.

[0327] In this embodiment, when the contact protrusion contacts the contact point of the connector 600, the contact area is extremely small, thereby generating extremely high contact pressure under the same clamping force. This high pressure can easily pierce the oxide layer, oil, or contaminants that may exist on the contact surface, forming a clean metal-metal contact, significantly reducing contact resistance, and ensuring the reliability of the electrical connection.

[0328] In other embodiments, refer to Figure 7 As shown, the mounting base 300 is also provided with a mounting cavity 310 and a mounting port 320 communicating with the mounting cavity 310. The conductive part 400 is disposed in the mounting cavity 310. The mounting port 320 is used to communicate with the mounting opening of the interior trim 10 so that the plug 600 can pass through the mounting opening of the interior trim 10 and enter the mounting cavity 310 through the mounting port 320 to electrically connect with the conductive part 400.

[0329] In this embodiment, the mounting base 300 is further provided with a mounting cavity 310 and a mounting opening 320 communicating with the mounting cavity 310. A conductive part 400 is disposed within the mounting cavity 310, meaning that multiple conductive spring pieces are integrally accommodated within the closed or semi-closed space formed by the mounting cavity 310. The mounting opening 320 is used to communicate with the mounting opening of the interior trim 10. The interior trim 10 has a mounting hole pre-drilled through its thickness, and the position of this mounting hole is aligned with the mounting opening 320.

[0330] When the mounting base 300 is fixed to the side of the interior trim 10 facing the outside of the vehicle (i.e., the side away from the user), the mounting opening 320 is precisely aligned with the mounting hole on the interior trim 10. The connector 600 is inserted from the user side of the interior trim 10, first passing through the mounting opening of the interior trim 10, then through the mounting opening 320 into the mounting cavity 310, and finally achieving electrical connection with the conductive part 400 located in the mounting cavity 310.

[0331] The shape and size of the mounting cavity 310 can be designed according to the overall outline of the conductive part 400, such as a rectangular or circular cavity. Its internal space is slightly larger than the unfolding range of the conductive spring to ensure that the conductive spring has sufficient room to move during elastic deformation, while avoiding interference with other components. The mounting port 320 can be an opening with the same shape as the mounting hole, such as a circular or rectangular opening, and its edges can be chamfered or have guide bevels to guide the connector 600 to enter smoothly.

[0332] Optionally, positioning ribs or limiting posts may be provided on the inner wall of the mounting cavity 310 to accurately position and fix each conductive spring of the conductive part 400, preventing displacement during installation or use. In addition, a sealing ring or elastic gasket may be provided between the mounting cavity 310 and the mounting opening 320 to improve dustproof and waterproof performance.

[0333] In this embodiment, the conductive part 400 is housed entirely within the mounting cavity 310, isolating it from the external environment. This effectively prevents dust, moisture, foreign objects, etc., from entering the contact area between the conductive spring and the connector 600, avoiding increased contact resistance or short circuit faults caused by contamination. This significantly improves the reliability and service life of the power interface device in harsh automotive environments.

[0334] The edge of the mounting port 320 can be provided with a guide bevel, which together with the mounting opening of the interior trim 10 forms a tapered guide channel, guiding the connector 600 to accurately enter the mounting cavity 310 and dock with the conductive part 400. Even in blind insertion or in low light conditions, the insertion can be easily completed, improving the user experience.

[0335] The mounting cavity 310 forms a rigid constraint on the conductive part 400, limiting the displacement of the conductive spring in the non-working direction. This ensures that the conductive spring maintains the correct posture and position in the vehicle vibration environment, thereby guaranteeing a stable clamping relationship between the contact section and the plug 600 contact point, and further consolidating the contact stability problem to be solved in the background art.

[0336] Furthermore, refer to Figure 11 As shown, the second connecting portion 500 has multiple discharge grooves at one end facing the sealing cover 100. These discharge grooves are spaced apart circumferentially along the second connecting portion 500, with their openings facing the sealing cover 100. Each discharge groove is located on the end face or end sidewall of the second connecting portion 500, and is not connected to the insertion hole channel. One end of each discharge groove leads to the outside of the mounting base 300, and the other end opens onto the end face of the second connecting portion 500 facing the sealing cover 100. When the sealing cover 100 is closed onto the mounting base 300, if condensation occurs between the sealing cover 100 and the second connecting portion 500 due to temperature or humidity changes, or if external moisture seeps into the area through the gap between the sealing cover 100 and the interior trim, this moisture or impurities can be discharged to the outside of the mounting base 300 via the discharge grooves, preventing accumulation at the connection interface between the sealing cover 100 and the second connecting portion 500. The width and depth of the discharge trough can be set according to actual needs to ensure sufficient drainage capacity without affecting the structural strength of the second connection part 500.

[0337] In another possible embodiment, the connecting section of each conductive spring is fixed to the bottom wall of the mounting cavity 310. The conductive spring also includes a conductive section that extends from the connecting section, passes through the bottom wall of the mounting cavity 310, and extends to the outside of the mounting cavity 310. The conductive section is used for electrical connection with the conductive wire harness.

[0338] It should be noted that, in this embodiment, the reference is... Figure 8 , Figure 12 , Figure 13 and Figure 14 As shown, the conductive spring can be a first conductive spring 410, a second conductive spring 420, or a third conductive spring 430. The connecting segment of the conductive spring can refer to the first connecting segment 412 of the first conductive spring 410, the second connecting segment 422 of the second conductive spring 420, or the third connecting segment 432 of the third conductive spring 430. The conductive segment of the conductive spring can refer to the first conductive segment 413 of the first conductive spring 410, the second conductive segment 423 of the second conductive spring 420, or the third conductive segment 433 of the third conductive spring 430.

[0339] In this embodiment, the connecting sections of the conductive spring are all fixed to the bottom wall of the mounting cavity 310. The connecting sections can be fixed to the bottom wall of the mounting cavity 310 by riveting, welding, screw fastening, or snap-fit ​​connection to ensure that the conductive spring does not shift during operation. The bottom wall of the mounting cavity 310 refers to the side wall opposite to the mounting port 320, that is, the side away from the user insertion direction.

[0340] In addition, the conductive spring also includes a conductive segment. This conductive segment extends from the connecting segment, passes through the bottom wall of the mounting cavity 310, and extends to the outside of the mounting cavity 310. A through-hole is provided on the bottom wall of the mounting cavity 310 corresponding to the position of each conductive spring, and the conductive segment extends through the through-hole to the external space of the mounting base 300. The conductive segment extending to the outside is used for electrical connection with the conductive wire harness, for example, by welding, crimping, or plugging terminals to achieve connection with the vehicle's power supply system or signal system.

[0341] The shape of the conductive segment can be designed according to actual wiring requirements, such as being straight, L-shaped, or hook-shaped, to facilitate mating with wire harness connectors. The length of the protruding part of the conductive segment is generally 5mm to 20mm to ensure sufficient operating space for wiring operations. The end of the conductive segment can also be equipped with structures such as fisheye terminals, wire grooves, or solder pads to improve the reliability of the connection with the conductive wire harness.

[0342] Optionally, a sealing ring or potting compound may be provided around the perforation on the bottom wall of the mounting cavity 310 to prevent dust or moisture from entering the interior of the mounting cavity 310 through the perforation, thereby further improving the protection level.

[0343] In this embodiment, the connecting section of the conductive spring is fixed to the bottom wall of the mounting cavity 310, so that each conductive spring has an independent fixing reference, avoiding positioning errors caused by deformation or tolerance accumulation in other parts of the mounting base 300. This fixing method ensures the positional accuracy of the abutting section and contact part of each conductive spring relative to the mounting opening 320, thereby ensuring accurate alignment and stable elastic clamping between the contact with the plug 600, which helps to solve the contact stability problem mentioned in the background art.

[0344] By incorporating a conductive segment that extends from the self-connecting section and protrudes into the mounting cavity 310, the electrical lead-out point of the conductive spring is placed directly outside the mounting base 300, eliminating the need for complex wire connection operations inside the mounting cavity 310. This allows the conductive spring to be pre-assembled as an independent sub-component on the mounting base 300, and then quickly connected to the conductive wire harness during final assembly via the conductive segment, significantly improving production efficiency and maintenance convenience.

[0345] After the conductive segment exits the mounting cavity 310, its connection point with the conductive wire harness is located outside the mounting base 300, far from the elastic clamping area of ​​the conductive spring. Thus, even if the conductive wire harness is subjected to pulling or vibration during vehicle operation, the force mainly acts on the exit point between the conductive segment and the bottom wall, rather than being directly transmitted to the contact section and the contact area. This avoids changes in clamping force or contact failure caused by the wire harness being subjected to stress, further enhancing contact stability.

[0346] In another embodiment, a potting compound layer 1600 is provided on the outer side of the bottom wall of the mounting cavity 310, and the potting compound layer 1600 covers and seals the portion of each conductive segment that extends out of the mounting cavity 310.

[0347] In this embodiment, refer to Figure 9 , Figure 10 and Figure 15 As shown, a potting compound layer 1600 is provided on the outer side of the bottom wall of the mounting cavity 310. The potting compound layer 1600 covers and seals the portions of each conductive section that extend out of the mounting cavity 310. The potting compound layer 1600 can be made of polymer materials with good adhesion, insulation and weather resistance, such as epoxy resin, polyurethane, and silicone rubber, and can be formed by processes such as injection molding, coating or potting.

[0348] During manufacturing, the conductive segments of each conductive spring are first inserted through perforations in the bottom wall of the mounting cavity 310. Then, liquid or semi-solid potting compound is applied to the outside of the bottom wall, completely covering the protruding conductive segments and the area around the perforations. After the potting compound cures, a dense protective layer is formed, isolating the conductive segments from the external environment. The thickness of the potting compound layer 1600 is typically 1mm to 5mm, and can be adjusted according to actual protection requirements and space constraints.

[0349] The outer surface of the potting compound 1600 can be flush with the bottom surface of the mounting base 300, or it can be slightly convex or concave, depending on the mold design. To ensure a sealing effect, the potting compound 1600 should form a firm bond with the bottom wall of the mounting cavity 310 and the surface of the conductive section, free from bubbles, cracks, and delamination defects.

[0350] Optionally, before applying the potting compound, an adhesion promoter can be applied to the surface of the conductive section or a plasma treatment can be performed to improve the adhesion between the potting compound and the metal surface. For applications requiring heat dissipation, the potting compound layer 1600 can also be a thermally conductive potting compound to help dissipate heat from the conductive section.

[0351] In this embodiment, the potting compound layer 1600 covers and seals the portions of each conductive segment extending out of the mounting cavity 310, completely sealing the gap between the conductive segment and the bottom wall perforation, effectively preventing external contaminants such as moisture, dust, and salt spray from entering the mounting cavity 310. This is particularly important for power interface devices installed inside vehicles (such as the center console, armrest box, or other areas that may come into contact with liquid splashes), achieving IP67 or even higher protection levels and significantly extending the product's service life.

[0352] Furthermore, the potting compound 1600 has excellent insulation properties, isolating the exposed portions of adjacent conductive sections from each other and preventing short-circuit faults caused by creepage or arcing between conductors. At the same time, the potting compound 1600 also prevents the conductive sections from accidentally contacting surrounding metal parts (such as body panels), improving the overall electrical safety of the vehicle.

[0353] Furthermore, the cured potting compound layer 1600 firmly fixes the conductive segment to the outer side of the bottom wall, essentially forming a rigid anchor point. When the conductive harness is subjected to vehicle vibration or external force, the tension is first applied to the potting compound layer 1600, rather than being directly transmitted to the connection between the conductive segment and the connecting segment. This protects the welding or riveting points inside the conductive spring from damage, further consolidating contact stability and better solving the problem of insufficient contact stability mentioned in the background art.

[0354] In some embodiments, reference is made to Figure 8 , Figure 12 , Figure 13 and Figure 14 As shown, the conductive part 400 includes three conductive springs, namely the first conductive spring 410, the second conductive spring 420 and the third conductive spring 430.

[0355] In this embodiment, the conductive part 400 includes three conductive springs, namely a first conductive spring 410, a second conductive spring 420, and a third conductive spring 430. All three conductive springs are installed within the mounting cavity 310 of the mounting base 300, and each has an independent connecting section, abutting section, and contact portion.

[0356] In one example, the first conductive spring 410 is used to electrically connect to the positive power contact of the connector 600, the second conductive spring 420 is used to electrically connect to the negative power contact of the connector 600, and the third conductive spring 430 is used to electrically connect to the ground or signal contact of the connector 600. The three conductive springs are arranged sequentially along the insertion direction of the connector 600, or arranged side by side in a direction perpendicular to the insertion direction, to avoid mutual interference.

[0357] The connecting sections of each conductive spring are fixed to the bottom wall of the mounting cavity 310, and each conductive spring has an independent conductive section extending out of the mounting cavity 310 to be electrically connected to the corresponding conductive wire harness. The contact portions of the three conductive springs can be set at different heights along the insertion direction to achieve corresponding connections with contacts at different axial positions on the connector 600.

[0358] Optionally, the three conductive springs can have identical structures or be designed differently depending on the current they carry. For example, the first conductive spring 410 and the second conductive spring 420 carry larger currents, and their contact width and thickness can be appropriately increased; the third conductive spring 430 is used for signal transmission, and its contact portion can adopt a finer bump structure to improve signal integrity.

[0359] In this embodiment, by setting three conductive springs, corresponding to the positive terminal of the power supply, the negative terminal of the power supply, and the ground or signal contact respectively, a complete power interface circuit is formed, which can provide reliable power transmission for most vehicle-mounted electrical devices (such as mobile phone charging, dashcam power supply, etc.), and realize the basic functions of the power interface device.

[0360] In some possible embodiments, the abutting section of the first conductive spring 410 is the first abutting section 411, and the contact portion of the first abutting section 411 is the first contact portion 4111.

[0361] The abutting section of the second conductive spring 420 is the second abutting section 421, and the contact portion of the second abutting section 421 is the second contact portion 4211.

[0362] The abutting section of the third conductive spring 430 is the third abutting section 431, and the contact portion of the third abutting section 431 is the third contact portion 4311.

[0363] Along the insertion direction of the connector 600, the first contact portion 4111 is furthest from the bottom wall of the mounting cavity 310, followed by the third contact portion 4311, and the second contact portion 4211 is closest to the bottom wall of the mounting cavity 310.

[0364] In this embodiment, refer to Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, the abutting section of the first conductive spring 410 is the first abutting section 411, and the contact portion on the first abutting section 411 is the first contact portion 4111; the abutting section of the second conductive spring 420 is the second abutting section 421, and the contact portion on the second abutting section 421 is the second contact portion 4211; the abutting section of the third conductive spring 430 is the third abutting section 431, and the contact portion on the third abutting section 431 is the third contact portion 4311.

[0365] Along the insertion direction of the connector 600 (i.e., from the mounting port 320 toward the bottom wall of the mounting cavity 310), the distances of each contact portion from the bottom wall of the mounting cavity 310 are distributed in a gradient. Specifically, the first contact portion 4111 is furthest from the bottom wall of the mounting cavity 310, i.e., closest to the mounting port 320; the third contact portion 4311 is next, located in the middle position; and the second contact portion 4211 is closest to the bottom wall of the mounting cavity 310, i.e., furthest from the mounting port 320.

[0366] To achieve the aforementioned height differences, the length of the contact section of each conductive spring can be adjusted accordingly. For example, the first contact section 411 of the first conductive spring 410 is the longest, allowing its first contact portion 4111 to extend to the position closest to the mounting opening 320; the third contact section 431 of the third conductive spring 430 has a moderate length; and the second contact section 421 of the second conductive spring 420 is the shortest, placing its second contact portion 4211 at the deepest position. Furthermore, the fixed positions of the connecting sections of each conductive spring on the bottom wall of the mounting cavity 310 can also be staggered along the insertion direction to accommodate variations in the length of the contact section.

[0367] Accordingly, the connector 600 has three contacts along its own direction (i.e., the insertion direction), located at axial positions corresponding to the first contact portion 4111, the third contact portion 4311, and the second contact portion 4211, respectively. When the connector 600 is inserted into the mounting port 320, it first contacts the first contact portion 4111 and forms an elastic clamp. As insertion continues, it contacts the third contact portion 4311 and the second contact portion 4211 in sequence until it is fully inserted. At the same time, the three contact portions form a reliable electrical connection with their respective contacts.

[0368] Optionally, each contact portion can adopt an arc-shaped clamping surface or a contact protrusion structure, the specific shape of which can be selected according to actual needs. Each conductive spring can be isolated from each other by an insulating partition to prevent contact short circuits during elastic deformation.

[0369] In this embodiment, since the first contact portion 4111, the third contact portion 4311, and the second contact portion 4211 are arranged sequentially along the insertion direction, the connector 600 gradually overcomes the elastic resistance of each conductive spring during insertion, rather than bearing the clamping force of all springs simultaneously. This hierarchical contact mechanism distributes the total insertion force to different insertion stages, effectively reducing the peak insertion force and improving the user's insertion and removal experience.

[0370] Initially, only the first contact portion 4111 contacts the first contact point of the connector 600, at which point the connector 600 is not yet fully positioned. As the insertion depth increases, the third contact portion 4311 and the second contact portion 4211 sequentially engage in contact, gradually correcting the orientation of the connector 600 until it is precisely aligned with each contact portion. This progressive alignment mechanism effectively avoids misalignment or jamming caused by simultaneous multi-point contact, improving connection reliability.

[0371] During hot-plugging, the first contact point (first contact 4111) will be subjected to a large surge current or arcing impact. By positioning the first contact 4111 closest to the mounting port 320, it will be the first to contact and the last to disengage, thus bearing the main impact of arcing. The second contact 4211, which is the last to contact, will only establish a connection in a stable state, and will be subjected to minimal impact. This design concentrates the losses on the easily replaceable or highly durable first conductive spring 410, extending the service life of the entire power interface device.

[0372] In a vehicle vibration environment, the three contact points are located at different heights, which constrains the connector 600 in multiple axial positions, similar to a multi-point support structure. Compared to a situation where all contact points are at the same height, this axially staggered layout can more effectively resist the axial movement and radial sway of the connector 600, further improving contact stability.

[0373] In one possible embodiment, the first conductive spring 410 and the second conductive spring 420 are used to connect to a power source, and the third conductive spring 430 is used to connect to a signal.

[0374] And / or, the first contact portion 4111 is used to abut against the first electrical connection area on the sidewall of the connector 600.

[0375] And / or, the second contact portion 4211 is used to abut against the second electrical connection area on the side wall of the connector 600.

[0376] And / or, the third contact portion 4311 is used to abut against the third electrical connection area of ​​the center portion of the connector 600.

[0377] It should be noted that the first electrical connection area on the side wall of the connector 600 can abut against one of the second conductive contacts 630 of the connector 600, the second electrical connection area on the side wall of the connector 600 can be another second conductive contact 630 of the connector 600, and the third electrical connection area on the side wall of the connector 600 can be the first conductive contact 620 of the connector 600.

[0378] In this embodiment, the first conductive spring 410 and the second conductive spring 420 are used to connect to the power supply, that is, to be electrically connected to the positive and negative terminals of the power supply, respectively, to provide power transmission for the vehicle-mounted electrical equipment. The third conductive spring 430 is used to connect signals, such as for transmitting data signals, detection signals, or grounding signals. In this way, power transmission and signal transmission are independently handled by different conductive springs, achieving functional separation.

[0379] Regarding the contact position, this embodiment provides a variety of optional or combined mating methods:

[0380] The first contact portion 4111 is used to abut against a first electrical connection area on the side wall of the connector 600. The first electrical connection area is located on the outer peripheral side wall of the connector 600, for example, an annular conductive strip or a local conductive sheet surrounding the side wall.

[0381] The second contact portion 4211 is used to abut against the second electrical connection area on the side wall of the connector 600. The second electrical connection area is also located on the side wall of the connector 600 and may be arranged axially offset from the first electrical connection area or separated in the circumferential direction.

[0382] The third contact portion 4311 is used to abut against the third electrical connection area at the center of the connector 600. The third electrical connection area is located at the center of the end face of the connector 600 or inside the central hole, for example, as a central contact or a central pin.

[0383] The three contact methods described above can be used individually or in any combination. For example, in a preferred embodiment, the first contact portion 4111 and the second contact portion 4211 respectively abut against two annular conductive strips on the side wall of the connector 600 to connect the positive and negative terminals of the power supply; simultaneously, the third contact portion 4311 abuts against the center contact point at the center of the connector 600 to achieve signal connection. This combination of internal and external contact layout makes full use of the different spatial dimensions of the connector 600.

[0384] To achieve contact at the center, the third abutment section 431 of the third conductive spring 430 can be designed to bend inward, so that its third contact portion 4311 is located near the central axis of the clamping space. The first abutment section 411 and the second abutment section 421 maintain a relatively lateral clamping structure.

[0385] Optionally, the first electrical connection area and the second electrical connection area may be located at different axial positions on the sidewall of the connector 600, corresponding to the height difference between the first contact portion 4111 and the second contact portion 4211. The third electrical connection area may be located at the center of the end face of the connector 600, matching the position of the third contact portion 4311.

[0386] In this embodiment, the power transmission function is assigned to the first conductive spring 410 and the second conductive spring 420, while the signal transmission function is assigned to the third conductive spring 430, thus achieving physical isolation between the power circuit and the signal circuit. This separation design effectively avoids ripple noise on the power line coupling to the signal line, ensuring the purity and integrity of signal transmission, and is particularly suitable for on-board charging scenarios requiring high-speed data transmission.

[0387] Furthermore, by positioning the first contact portion 4111 and the second contact portion 4211 to abut against the electrical connection area on the side wall of the connector 600, the large area and ease of positioning of the side wall provide a large contact area and stable clamping force. Simultaneously, positioning the third contact portion 4311 to abut against the electrical connection area at the center of the connector 600 leverages the advantage of the center being less susceptible to external force displacement, maintaining reliable contact even under vibration. This combined internal and external contact layout complements each other, further enhancing overall contact stability.

[0388] In other possible embodiments, the connecting segment of the first conductive spring 410 is the first connecting segment 412, the connecting segment of the second conductive spring 420 is the second connecting segment 422, and the connecting segment of the third conductive spring 430 is the third connecting segment 432.

[0389] The first conductive spring 410 also includes a first conductive segment 413, which extends from the first connecting segment 412, passes through the bottom wall of the mounting cavity 310, and extends to the outside of the mounting cavity 310 for electrical connection with the first wire harness 20.

[0390] And / or, the second conductive spring 420 further includes a second conductive segment 423, which extends from the second connecting segment 422, passes through the bottom wall of the mounting cavity 310, and extends to the outside of the mounting cavity 310 for electrical connection with the second wire harness 30.

[0391] And / or, the third conductive spring 430 also includes a third conductive segment 433, which extends from the third connecting segment 432, passes through the bottom wall of the mounting cavity 310, and extends to the outside of the mounting cavity 310 for electrical connection with the third wire harness 40.

[0392] In this embodiment, the connecting segment of the first conductive spring 410 is designated as the first connecting segment 412, the connecting segment of the second conductive spring 420 is designated as the second connecting segment 422, and the connecting segment of the third conductive spring 430 is designated as the third connecting segment 432. Each connecting segment is fixed to the bottom wall of the mounting cavity 310.

[0393] To further facilitate electrical outgoing, this embodiment provides a variety of optional or combined outgoing structure options:

[0394] The first conductive spring 410 also includes a first conductive segment 413, which extends from the first connecting segment 412, passes through the bottom wall of the mounting cavity 310, and extends to the outside of the mounting cavity 310 for electrical connection with the first wire harness 20. The first wire harness 20 may be a positive power supply wire harness.

[0395] The second conductive spring 420 also includes a second conductive segment 423, which extends from the second connecting segment 422, passes through the bottom wall of the mounting cavity 310, and extends to the outside of the mounting cavity 310 for electrical connection with the second wiring harness 30. The second wiring harness 30 may be a negative power supply wiring harness.

[0396] The third conductive spring 430 also includes a third conductive segment 433, which extends from the third connecting segment 432, passes through the bottom wall of the mounting cavity 310, and extends to the outside of the mounting cavity 310 for electrical connection with the third wiring harness 40. The third wiring harness 40 may be a signal wiring harness.

[0397] The above three lead-out structures can be used individually or in any combination. For example, in a preferred embodiment, the first conductive segment 413, the second conductive segment 423, and the third conductive segment 433 are simultaneously provided and electrically connected to the corresponding first wire harness 20, second wire harness 30, and third wire harness 40, respectively, to achieve independent lead-out of power and signal. In another simplified embodiment, only the first conductive segment 413 and the second conductive segment 423 are provided for power connection, and the third conductive segment 433 of the third conductive spring 430 can be omitted and connected to the signal wire harness by other means (such as direct soldering).

[0398] The shape of each conductive segment can be designed according to the wiring space, such as being straight, L-shaped, or hook-shaped. A through-hole is provided on the bottom wall of the mounting cavity 310 corresponding to each conductive segment. After the conductive segment passes through the through-hole, its protruding part can be fixed to the wire harness terminal by welding, crimping, or plugging. To prevent short circuits, sufficient electrical clearance is maintained between each conductive segment, and insulating sleeves can be installed.

[0399] Optionally, the protruding portions of each conductive segment can be further sealed with a potting compound layer 1600 to improve protective performance, as described above.

[0400] In this embodiment, by providing an independent conductive segment for each conductive spring, the electrical lead-out paths of each conductive spring are made independent, avoiding current convergence or signal crosstalk caused by sharing lead-out points. Simultaneously, the independent conductive segments are connected to their respective wiring harnesses, facilitating differentiation and management within the overall vehicle wiring harness layout and reducing assembly and maintenance difficulties.

[0401] The conductive section extends integrally from the connecting section and passes through the mounting cavity 310, reducing intermediate connection links (such as jumpers or adapter terminals) and thus reducing the number of potential failure points. This integrated structure has higher mechanical strength in vehicle vibration environments, making it less prone to loosening or breakage, further consolidating the reliability of the electrical connection between the conductive spring and the wiring harness, and indirectly ensuring stable contact between the conductive spring and the connector 600 contacts.

[0402] In some possible embodiments, refer to Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, the clamping space between the two first abutting sections of the first conductive spring 410 is the first clamping space. The first clamping space is used to elastically clamp the first electrical connection area, and the first contact portion 4111 is located in the first clamping space.

[0403] And / or, the clamping space between the two second abutting sections of the second conductive spring 420 is the second clamping space, which is used to elastically clamp the second electrical connection area, and the second contact portion 4211 is located in the second clamping space.

[0404] And / or, the clamping space between the two third abutment sections of the third conductive spring 430 is the third clamping space, which is used to elastically clamp the third electrical connection area, and the third contact part 4311 is located in the third clamping space.

[0405] It should be noted that the first electrical connection area on the side wall of the connector 600 can abut against one of the second conductive contacts 630 of the connector 600, the second electrical connection area on the side wall of the connector 600 can be another second conductive contact 630 of the connector 600, and the third electrical connection area on the side wall of the connector 600 can be the first conductive contact 620 of the connector 600.

[0406] In this embodiment, the clamping space between the two first abutment sections 411 of the first conductive spring 410 is referred to as the first clamping space. This first clamping space is used to elastically clamp the first electrical connection area, and the first contact portion 4111 is located within the first clamping space. When the connector 600 is inserted, the first electrical connection area enters the first clamping space and is elastically clamped from both sides by the first contact portions 4111 on the two first abutment sections 411, forming a reliable electrical connection.

[0407] The clamping space between the two second abutment sections 421 of the second conductive spring 420 is referred to as the second clamping space. This second clamping space is used to elastically clamp the second electrical connection area, and the second contact portion 4211 is located within the second clamping space. When the connector 600 is inserted, the second electrical connection area enters the second clamping space and is elastically clamped from both sides by the second contact portions 4211 on the two second abutment sections 421.

[0408] The clamping space between the two third abutment sections 431 of the third conductive spring 430 is referred to as the third clamping space. This third clamping space is used to elastically clamp the third electrical connection area, and the third contact portion 4311 is located within the third clamping space. When the connector 600 is inserted, the third electrical connection area enters the third clamping space and is elastically clamped from both sides by the third contact portions 4311 on the two third abutment sections 431.

[0409] The three clamping spaces described above can be set individually or in any combination. For example, in a preferred embodiment, the first clamping space, the second clamping space, and the third clamping space coexist, respectively corresponding to the elastic clamping of the first electrical connection area, the second electrical connection area, and the third electrical connection area, achieving independent clamping at three points. In another simplified embodiment, only the first and second clamping spaces are set for power connection, and the third conductive spring 430 can adopt other contact methods (such as a single-sided spring contacting the center contact point) without forming a complete clamping space.

[0410] The width of each clamping space (i.e., the minimum distance between two abutting sections) is slightly smaller than the thickness of the corresponding electrical connection area to ensure sufficient elastic deformation and clamping force during insertion. The axial position of each clamping space matches the axial position of the corresponding electrical connection area to ensure accurate alignment of each contact after insertion.

[0411] In one embodiment, reference is made to... Figure 10 As shown, the mounting base 300 is provided with a first wire harness limiting part 330, a second wire harness limiting part 340 and a third wire harness limiting part 350. The first wire harness limiting part 330 is used to fix the first wire harness 20, the second wire harness limiting part 340 is used to fix the second wire harness 30, and the third wire harness limiting part 350 is used to fix the third wire harness 40.

[0412] In this embodiment, the mounting base 300 is provided with a first wire harness limiting part 330, a second wire harness limiting part 340, and a third wire harness limiting part 350. Specifically, these three wire harness limiting parts are physical structures disposed on the outside of the mounting base 300 (usually located on the side facing away from the interior trim 10), used to orderly constrain and fix the first wire harness 20, the second wire harness 30, and the third wire harness 40, respectively. Each wire harness limiting part can be designed in various forms, such as: a wire-holding groove with an opening into which the wire harness can be pressed and embedded; a bracket with a binding post or wire hole for cable ties to pass through to bundle the wire harness; or a pair of opposing clamping pieces forming a clamping space that can be elastically opened and closed.

[0413] During assembly and wiring, the operator guides and secures the first wire harness 20, the second wire harness 30, and the third wire harness 40, which emerge from the conductive spring contacts, to their corresponding wire harness limiting parts according to their electrical functions (such as positive power, negative power, and signal). For example, the first wire harness 20 from the first conductive spring contact 410 is snapped into or tied to the first wire harness limiting part 330; the second wire harness 30 from the second conductive spring contact 420 is fixed to the second wire harness limiting part 340; and the third wire harness 40 from the third conductive spring contact 430 is fixed to the third wire harness limiting part 350. In this way, after leaving the electrical connection point of the mounting base 300, the three wire harnesses are immediately diverted, guided, and mechanically locked onto their respective designated paths and positions, preventing the wire harnesses from tangling, drooping disorderly, or interfering with surrounding components.

[0414] In this embodiment, the wiring harnesses with different electrical functions (high-current power supply, low-current signal) are physically separated and independently fixed at the source, effectively preventing insulation wear and short-circuit risks caused by mutual friction and entanglement of the wiring harnesses, as well as interference from the electromagnetic field of the power line to the signal line. Each wiring harness limiting part provides an independent stress relief point for the corresponding wiring harness, which can absorb the mechanical energy transmitted to the wiring harness by vehicle vibration, preventing the vibration and the weight of the wiring harness itself from directly pulling on the fragile welding points or connection points of the conductive spring, thereby protecting the integrity of the entire electrical channel from the external wiring harness to the internal contact part, which is the basic guarantee for the long-term reliable electrical connection.

[0415] Furthermore, three clearly marked and fixed-position wire harness limiting points provide a clear "map" for wiring operations on the production line. Assembly workers can quickly and accurately place wires of different colors or labeled wires into their corresponding slots without needing to make judgments, achieving error-proof assembly. The standardized wiring method ensures that the internal wire harness layout of each product is exactly the same, which is not only aesthetically pleasing but also facilitates subsequent automated visual inspection (checking whether the wire harness is in the slot) and electrical testing, improving the consistency of production quality. Clear wire harness separation also facilitates fault diagnosis and circuit traceability.

[0416] Organizing and securing the wire harness in an orderly manner prevents tangled bundles from piling up behind the mounting base 300, promoting airflow and providing a better heat dissipation environment for the mounting base 300 and the wire harness connection points. When repairing or replacing a single wire harness, maintenance personnel can easily identify and operate on that harness individually without untying the entire bundle, greatly simplifying the maintenance process and reducing the risk of improper maintenance affecting other intact lines.

[0417] In some possible embodiments, the outer wall of the mounting sleeve 700 is provided with a first anti-fooling part (not shown in the figure), and the inner wall of the insertion hole channel 510 is provided with a second anti-fooling part (not shown in the figure) that cooperates with the first anti-fooling part.

[0418] In this embodiment, a first anti-foolproof part is provided on the outer wall of the mounting sleeve 700. This first anti-foolproof part is a structure with specific geometric features, such as a boss, a guide rib at a specific angle, a protrusion of a unique size, or a non-circular symmetrical plane, or a protrusion on the outer wall of the mounting sleeve 700 in the above embodiment. It should be noted that this protrusion is different in color from other protrusions on the outer wall of the mounting sleeve 700, so as to facilitate the user to quickly locate this protrusion.

[0419] Correspondingly, on the inner wall of the socket channel 510 of the mounting base 300, a second anti-fooling part is machined or formed that perfectly matches and complements the first anti-fooling part in shape, position, and orientation. This second anti-fooling part can be, for example, a recessed area at a specific location, a narrow groove for guide ribs to slide into, or a non-circular mating surface. It can also be a groove on the inner wall of the socket channel 510. It should be noted that this groove is a different color from other grooves on the inner wall of the socket channel 510, so as to facilitate the user to quickly locate this groove.

[0420] In this embodiment, the explicit mistake-proof design provides intuitive physical guidance for assembly operations. Operators do not need to carefully identify markings or make repeated attempts; they can quickly find the correct insertion position by feel alone, thereby shortening assembly time and making the assembly process smoother and more user-friendly. For automated assembly lines, this feature also facilitates accurate orientation recognition and verification by visual or force sensors.

[0421] Furthermore, the geometric fit between the first and second anti-mistake parts physically and uniquely locks the precise circumferential angle of the mounting sleeve 700 within the insertion channel 510. This forced angular positioning directly determines the absolute circumferential phase of the threads (or other connecting structures) on the inner wall of the mounting sleeve 700. When the first connecting part 200 is screwed into the mounting sleeve 700 via threads or other means, its own orientation is thus uniquely determined and fixed. Finally, when the connector 600 is inserted into the insertion channel formed by the first connecting part 200 and the mounting base 300, its final insertion angle and position are also constrained and determined by this interlocking mechanism. Therefore, this anti-mistake structure fundamentally ensures the consistency and repeatability of the entire chain of spatial positions from the mounting base 300, the mounting sleeve 700, the first connecting part 200 to the final connector 600.

[0422] For multi-pole, polarized, or position-sensitive power / signal interfaces, even minute angular deviations in the connector 600 can lead to poor contact or functional failure. The foolproof design of this embodiment, through the aforementioned full-chain fixing, ensures that every electrical connection area on the connector 600 is perfectly aligned with the corresponding terminal on the conductive part 400 inside the power interface device each time it is inserted. This eliminates contact uncertainties caused by accumulated component assembly tolerances or arbitrary insertion angles by the user, resulting in extremely high contact pressure consistency and signal integrity in the electrical connection. It eliminates the risk of increased contact resistance, arcing, signal errors, or physical damage to the interface caused by angular deviations, thus improving the reliability of the electrical connection.

[0423] Furthermore, the fixed position across the entire chain ensures that every insertion and removal operation is performed under identical mechanical and electrical conditions. This avoids uneven wear of terminals, localized stress concentration, or abnormal stress on the connector housing caused by changes in position or angle, resulting in more uniform wear on all terminals and significantly extending the interface's insertion and removal life.

[0424] In some embodiments, the outer peripheral wall of the mounting base 300 is also provided with an alignment mark (not shown in the figure), which is used to indicate the installation orientation of the mounting sleeve 700.

[0425] In this embodiment, an alignment mark is added to the outer peripheral wall of the mounting base 300. The alignment mark is a mark with clear visual or tactile identification features, and its form can be a raised arrow, a recessed triangle, a contrasting color block, a scribed line, or a specific graphic symbol. This alignment mark is precisely positioned at a specific circumferential orientation on the outer peripheral wall of the mounting base 300, and this orientation is pre-aligned circumferentially with directional features on the mounting sleeve 700 (e.g., a first anti-fooling part, a marking point, or an asymmetrical structure on the outer wall of the mounting sleeve 700).

[0426] The specific assembly operation is as follows: Before inserting the mounting sleeve 700 into the insertion channel 510 of the mounting base 300, the operator first observes the alignment marks on the outer peripheral wall of the mounting base 300 to clarify the indicated orientation. Then, the circumferential angle of the mounting sleeve 700 is adjusted so that its directional features (e.g., the side where the anti-foolproof boss is located) are aligned with the direction indicated by the alignment marks on the mounting base 300. Finally, while maintaining this alignment, the mounting sleeve 700 is axially pushed or screwed into the insertion channel 510. During this process, the alignment marks serve as an external, visual reference, particularly useful when the internal structure of the mounting base 300 is not visible after installation on the vehicle, or in scenarios with poor lighting or limited operating space, providing crucial guidance for the pre-orientation of the mounting sleeve 700.

[0427] In this embodiment, when the internal structure of the mounting base 300 is not visible, the alignment marks on the outer peripheral wall provide a unique and clear external orientation reference. This transforms the circumferential alignment operation of the mounting sleeve 700 from a "blind operation" or "trial and error" process relying on feel and experience into a direct and definite "visual positioning" process. This not only significantly shortens the assembly time of individual components and improves the assembly line cycle time, but also prevents assembly rework caused by incorrect orientation judgment from the outset, ensuring a high pass rate for the first assembly.

[0428] In some embodiments, reference is made to Figure 3 and Figure 4 As shown, the projection of the first connecting part 200 toward the sealing cover 100 is located inside the sealing cover 100.

[0429] In one possible embodiment, refer to Figure 2 , Figure 3 and Figure 4 As shown, the first connecting part 200 and the sealing cover 100 are integrally formed.

[0430] In this embodiment, the sealing cap 100 and the first connecting portion 200 are designed within the same mold cavity. Molten raw material is filled into this cavity through a single injection molding process (for plastic materials) or die casting (for metal materials). After the raw material cools and solidifies, the resulting part, the main body of the sealing cap 100 used to fit the interior trim 10 and form the exterior, and the first connecting portion 200 used to extend towards the interior trim 10 and achieve mechanical connection, are continuous and uniform in material and seamlessly connected in structure. There are no physical interfaces, adhesive surfaces, or mechanical fastening interfaces between them. The first connecting portion 200 is essentially a functional extension of the main body of the sealing cap 100 in a specific direction; the two are an inseparable whole.

[0431] In the "two-way clamping" fixation, the first connecting part 200 is the core force-transmitting component that bears the tensile force from the second connecting part 500. The one-piece molding eliminates any potential connection interfaces (such as threads, snaps, or adhesive surfaces) between the sealing cover 100 and the first connecting part 200. This allows the tensile force received from the distal end of the first connecting part 200 to be directly transmitted without loss or stress concentration to the entire back plate area of ​​the sealing cover 100 through its root, and then evenly distributed to the interior trim 10. This avoids any loss of clamping force due to microscopic slippage, deformation, or failure of the connection interface, ensuring the long-term stability of the clamping system from the most basic component level.

[0432] In other embodiments, refer to Figure 4 As shown, the outer side wall of the first connecting part 200 is provided with a clamping surface 230, which is used for clamping external tools.

[0433] In this embodiment, at least one clamping surface 230 is specially provided on the outer side wall of the first connecting portion 200.

[0434] Specifically, the clamping surface 230 is a structural surface formed on the outer wall of the first connecting portion 200, possessing specific geometric features to facilitate reliable clamping and force application by external tools. In a preferred embodiment, the clamping surface 230 can be a pair of parallel and opposing planes, forming a structure similar to a "wrench plane"; it can also be a polygonal cross-section (such as a hexagon) machined circumferentially on the outer wall of the first connecting portion 200, forming a "bolt head" type structure; or it can be a strip-shaped area extending axially with anti-slip texture. These clamping surfaces 230 are typically located in easily accessible positions near the root (i.e., near the sealing cap 100) or middle section of the first connecting portion 200.

[0435] When performing assembly, debugging, or disassembly operations, the operator (or automated equipment) can select a matching general-purpose tool, such as an adjustable wrench, open-end wrench, socket, or special clamping pliers. The working part of the tool (such as the jaws or the inner wall of the socket) is brought into contact with the clamping surface 230. Subsequently, by applying rotational torque or axial force through the tool, the first connecting part 200 can be precisely and efficiently driven to screw in, screw out, or move axially to complete the connection, fastening, or separation from the second connecting part 500 (or mounting sleeve 700).

[0436] In this embodiment, the presence of the clamping surface 230 allows operations on the first connecting portion 200 (such as rotation to adjust the circumferential angle of the sealing cap 100, final tightening, or fault disassembly) to be easily integrated into automated assembly lines, where they can be quickly completed by a robotic arm using standard tools. In after-sales service scenarios, maintenance technicians do not need to find special leverage points or use unconventional methods that may damage the product (such as directly clamping with pipe wrenches); they can complete the operation efficiently and without damage using conventional tools. This significantly improves production and maintenance efficiency, reduces operational difficulty and time costs, and makes the entire process more standardized, controllable, and traceable.

[0437] Furthermore, the dedicated clamping surface 230 guides the operating force to a specially designed area with sufficient strength, preventing the operator from being forced to apply force to the outer surface of the sealing cap 100, non-stressed areas (such as threaded sections) of the first connection 200, or internal precision structures, which would be possible without the clamping surface 230. This effectively prevents scratches on the surface of the sealing cap 100 due to tool slippage, deformation of the first connection 200 due to localized stress concentration, or thread damage caused by direct torque acting on the threads. This extends the product's service life.

[0438] In rare cases, such as when internal threads are corroded or foreign objects are stuck, causing abnormal tightness in the connection, the standardized clamping surface 230, combined with a matching extended lever arm tool (such as a long-handled wrench), makes it possible to apply a larger separation torque safely and controllably, which is an important troubleshooting aid design.

[0439] In some possible embodiments, refer to Figure 5 , Figure 7 and Figure 8 As shown, the mounting base 300 has a mounting cavity 310 and a mounting opening 320 facing the sealing cover 100. The mounting opening 320 communicates with the mounting cavity 310, and the conductive part 400 is disposed in the mounting cavity 310. The portion of the mounting base 300 surrounding the mounting opening 320 constitutes a second connecting part 500, and the inner wall of the mounting opening 320 defines an insertion channel 510.

[0440] In this embodiment, the mounting base 300 is a housing structure with a receiving space, which includes a mounting cavity 310. This mounting cavity 310 is a recessed space or chamber primarily used to accommodate and protect the conductive part 400. At the end of the mounting base 300 facing the sealing cover 100, a mounting opening 320 is provided. This mounting opening 320 serves as a channel opening, directly communicating with the internal mounting cavity 310, forming a necessary path from the outside to the conductive part 400. The conductive part 400, i.e., the core terminal assembly that realizes electrical connection, is arranged and fixed inside the mounting cavity 310.

[0441] Furthermore, the second connecting portion 500 is specifically defined as the solid portion surrounding the mounting opening 320 on the mounting base 300. This part of the structure constitutes the "interface area" of the mounting base 300 for physical connection and mating with the first connecting portion 200. Meanwhile, the insertion channel 510 is specifically defined as the internal space channel defined by the inner wall of the mounting opening 320 itself. In other words, the mounting opening 320 is not a simple hole; its inner wall directly constitutes part of the insertion channel for guiding the insertion of the connector 600.

[0442] In this embodiment, the conductive part 400 is built into a dedicated mounting cavity 310, and its position is precisely fixed by the geometry of the mounting cavity 310, unaffected by external assembly stress. The mounting port 320, as the only controlled path to the conductive part 400, has dimensions and axis machining accuracy that directly determine the accuracy of the mating between the connector 600 and the conductive part 400. This dual protection mechanism of "cavity positioning and channel guidance" ensures extremely high repeatability and reliability of the electrical connection. Simultaneously, the mounting cavity 310 forms a semi-enclosed protective space, isolating the conductive part 400 from the complex external environment (such as wire harnesses and other metal parts), effectively preventing accidental short circuits, mechanical impacts, and direct dust intrusion.

[0443] Furthermore, the solid area surrounding the mounting opening 320 is defined as the second connecting portion 500, meaning that the mechanical connection force acts directly on one of the thickest and strongest parts of the mounting base 300 body. This provides an ideal force-bearing basis for achieving a high-strength connection (such as threaded fastening) between the first connecting portion 200 and the second connecting portion 500, ensuring the effective transmission of clamping force. Simultaneously, since the insertion channel 510 is directly defined by the inner wall of the mounting opening 320, it is concentric and integral with the second connecting portion 500. This ensures a natural unity between the alignment of the mechanical connection and the alignment of the electrical channel, avoiding assembly interference or difficulty in insertion / removal due to component misalignment.

[0444] The mounting cavity 310 provides initial storage and routing space for the wire harness leading out from the conductive part 400, making the internal wiring more organized. The mounting port 320, as a clear boundary, also provides a clear interface for setting secondary seals at this location (such as adding a sealing ring to the end face of the mounting port 320 to seal the gap between the sealing cover 100 and the mounting base 300 after mating), which helps to improve the dustproof and waterproof rating of the entire interface device.

[0445] In another possible embodiment, refer to Figure 9 , Figure 10 and Figure 11 As shown, at least one positioning rib 1100 is provided at intervals on the outer peripheral wall of the mounting base 300. The positioning rib 1100 is configured to be able to be inserted into the corresponding structure of the first support plate located on the side of the interior trim 10 facing the mounting base 300 when the mounting base 300 is assembled toward the interior trim 10, so that the mounting base 300 is positioned on the first support plate.

[0446] In this embodiment, the positioning ribs 1100 are rib-like, block-like, or guide plate-like structures that protrude outward from the outer peripheral wall of the mounting base 300. There can be one, two, or more ribs, distributed asymmetrically or symmetrically along the outer periphery of the mounting base 300. Each positioning rib 1100 has a specific cross-sectional shape (such as rectangular or trapezoidal) and a guide bevel, and its end can be designed as a wedge or chamfer for easy insertion.

[0447] The positioning rib 1100 is used to pre-fit with a first support plate inside the vehicle (such as a dashboard crossbeam, a bracket on the body sheet metal, or a special interior panel). The first support plate is pre-equipped with a corresponding structure that corresponds to the shape, size, and position of the positioning rib 1100. This corresponding structure can be a slot or guide groove that matches the cross section of the positioning rib 1100, or it can be a positioning hole or notch into which the end of the positioning rib 1100 is inserted.

[0448] During assembly, the mounting base 300 (pre-installed with the conductive part 400) moves from the outside of the vehicle (such as the interior space of the dashboard) toward the interior trim 10. The operator (or robotic arm) first roughly aligns the positioning rib 1100 on the outer peripheral wall of the mounting base 300 with the corresponding structure on the first support plate. Then, the mounting base 300 is further advanced, allowing the positioning rib 1100 to slide in along the guide surface of the corresponding structure until it is fully inserted, fitted, or seated in the predetermined position. At this point, although the mounting base 300 is not yet finally secured to the first connecting part 200 of the sealing cover 100 via its second connecting part 500, it has been pre-restricted and roughly positioned in multiple degrees of freedom (especially in the direction perpendicular to the interior trim 10 and the direction of rotation about the axis) through the cooperation of the positioning rib 1100 and the first support plate. This provides a stable and accurate initial reference for subsequent precise alignment of the mounting holes on the interior trim 10 and final connection and securing of the mounting base 300 to the sealing cover 100.

[0449] In related technologies, the mounting base 300 is in a "free-floating" state within the spacious interior space of the vehicle body, requiring the operator to manually support it and align it with the mounting holes on the back of the interior trim 10, which is laborious and difficult to align. In this embodiment, the positioning rib 1100 engages with the corresponding structure on the first support plate, providing the mounting base 300 with a clear and quickly achievable anchor point. The operator simply aligns the positioning rib 1100 and pushes it into the corresponding structure, and the mounting base 300 is automatically guided to an area close to its final working position, maintaining a basically correct posture. This eliminates the tedious fine-tuning and alignment time, simplifies and standardizes the assembly process, significantly improves production line cycle time and assembly efficiency, and reduces the operator's workload.

[0450] The pre-positioning mechanism in this embodiment ensures that, before the final fastening operation begins, the mounting base 300 is in a stable state very close to its designed position relative to the vehicle body structure (first support plate) and indirectly relative to the interior trim 10. This greatly reduces the difficulty of alignment and avoids problems such as the threads of the first and second connecting parts 500 not engaging or the buckles being difficult to close due to the mounting base 300 wobbling in the air, thereby ensuring that the core connection steps can be completed smoothly and accurately.

[0451] During vehicle use, the power interface is subjected to forces and vibrations from plugging and unplugging operations. After the positioning rib 1100 is inserted into the first support plate, the mating pair formed with it can share some of the load from the interface, especially the shear force parallel to the plane of the interior trim 10. This changes the stress mode of the mounting base 300, changing it from being solely dependent on the connection point with the sealing cover 100 to a system where part of the load is transferred to the more robust vehicle body support structure through the positioning rib 1100. This reduces the burden on the connection between the sealing cover 100 and the mounting base 300, and makes the entire interface device more securely integrated with the vehicle body, potentially indirectly improving its overall vibration and shock resistance.

[0452] In one possible embodiment, refer to Figure 5 , Figure 9 , Figure 10 and Figure 11 As shown, the mounting base 300 is also provided with at least one inverted positioning part 1200. The inverted positioning part 1200 extends from the mounting base 300 in a direction away from the interior trim 10 and protrudes from the mounting base 300. The inverted positioning part 1200 is configured to be able to be inserted into the corresponding structure of the second support plate located on the side of the mounting base 300 away from the interior trim 10 when the mounting base 300 is assembled with its back to the interior trim 10, so that the mounting base 300 is positioned on the second support plate.

[0453] In this embodiment, the inverted positioning portion 1200 is a protruding structure extending away from the interior trim 10 from the main body of the mounting base 300 (typically its surface facing the exterior of the vehicle or away from the interior trim 10). In a typical application, such as when a power interface device is installed on the vehicle headliner 10, the interior trim 10 is located below (inside the vehicle), and the mounting base 300 needs to be installed upwards to the headliner support structure. In this case, the inverted positioning portion 1200 extends vertically or obliquely upwards from the "upper surface" of the mounting base 300 and extends beyond the contour of the mounting base 300 main body. Its structural form can be a positioning post, a positioning pin, a protrusion with a guide bevel, or a long strip rib with a specific cross-section.

[0454] The function of the inverted positioning part 1200 is to cooperate with another support structure inside the vehicle, namely a second support plate. In the case of roof mounting, this second support plate can be a roof beam, a reinforcing plate, or a specially designed mounting bracket. The second support plate has corresponding structures that match the shape and size of the inverted positioning part 1200, such as positioning holes, slots, or notches.

[0455] During the inverted assembly process (taking roof mounting as an example), the sealing cover 100 is first attached to the lower surface of the headliner trim 10 from inside the vehicle (passenger compartment). Then, the operator lifts the mounting base 300 upwards from inside the vehicle, allowing it to pass through the mounting opening of the headliner trim 10, while simultaneously aligning the inverted positioning part 1200 on the mounting base 300 upwards with the corresponding structure on the second support plate at the roof. The mounting base 300 is then pushed upwards further, causing the inverted positioning part 1200 to insert and settle into the corresponding structure. At this point, the mounting base 300 is pre-constrained and positioned in a direction parallel to the plane of the trim 10 and in a direction rotating about the vertical axis, providing a stable and accurate initial reference for subsequent tightening or connecting of the first connecting part 200 and the second connecting part 500 from bottom to top inside the vehicle, effectively overcoming the inconvenience of operation in a confined overhead space and the influence of gravity.

[0456] In this embodiment, in an inverted assembly scenario (such as a car roof), the mounting base 300 needs to overcome gravity to maintain an upward posture before final tightening, which is extremely inconvenient. In this embodiment, the inverted positioning part 1200 extends upward and inserts into the second support plate, essentially providing a "suspension point" or "guide rail," achieving initial support and pre-fixation of the mounting base 300 in the direction of gravity. This eliminates the need for the operator to continuously resist gravity to lift the mounting base 300, freeing their hands for precise connection operations. This fundamentally solves the biggest operational challenge in inverted assembly, significantly improving assembly feasibility and efficiency, and ensuring that the mounting base 300 will not fall due to gravity and become misaligned with the sealing cover 100 before tightening.

[0457] Because the interior space of areas such as the roof and pillars is typically narrow and obstructed, the inverted positioning unit 1200 provides clear tactile feedback (such as a "click" sound or a sudden change in resistance) during the insertion of the second support plate into the corresponding structure. Even without visual inspection, the operator can clearly perceive that the mounting bracket 300 has reached the preset positioning position. This provides crucial physical guidance and confirmation for achieving precise spatial alignment between the mounting bracket 300 and the vehicle body structure, and indirectly between the mounting bracket 300 and the sealing cover 100, under adverse visual conditions, ensuring that subsequent core connection steps can be completed accurately.

[0458] Furthermore, through the cooperation between the inverted positioning part 1200 and the second support plate, the mounting base 300, under vibration conditions, not only relies on the "two-way clamping" with the sealing cover 100, but also gains an additional direct connection point with the more robust vehicle body structure (the second support plate). This "multi-point fixing" strategy can better resist the additional alternating loads and torques generated by the inverted interface due to its own weight and inertia when the vehicle is in motion, especially on bumpy roads, preventing long-term micro-movements of the interface.

[0459] By integrating positioning features for both upright mounting (positioning rib 1100) and inverted mounting (inverted positioning part 1200) onto the same mounting base 300 body, this embodiment allows the same power interface device to be flexibly adapted to vastly different installation positions and orientations within a vehicle, from the center console and dashboard (upright mounting) to the headliner and trunk (inverted mounting), without altering the core structure. This significantly enhances the product's platformization and versatility, reduces the R&D and material costs for OEMs to develop different interfaces for different locations, and achieves an efficient solution that meets diverse needs through a single design.

[0460] In another embodiment, reference Figure 5 , Figure 9 , Figure 10 and Figure 11 As shown, the mounting base 300 is also provided with at least one inverted hook-up portion 1300, which extends from the mounting base 300 in a direction away from the interior trim 10 and protrudes from the mounting base 300; the inverted hook-up portion 1300 is configured to engage with a second support plate located on the side of the mounting base 300 away from the interior trim 10.

[0461] In this embodiment, the inverted hook-on portion 1300 is a cantilever structure that extends from the body of the mounting base 300 (typically its surface or side facing away from the interior trim 10) away from the interior trim 10 and beyond the outline of the mounting base 300. Its form can be designed as a hook, barb, cantilever with a spring-loaded latch, or a rod with a retractable latch head. The end or specific portion of the inverted hook-on portion 1300 forms a hook, boss, or enlarged head for "hooking".

[0462] The core function of the inverted mounting bracket 1300 is to achieve a "hook-and-loop" connection with the vehicle's second support plate. In scenarios such as roof mounting, the second support plate can be a roof beam, sheet metal flange, or a specially designed bracket with a notch. The hook-and-loop connection refers to the inverted mounting bracket 1300 hooking, overlapping, or snapping onto the edge, hole, or protrusion of the second support plate using its specific structure. It mainly utilizes gravity or structural interlocking to provide a preliminary connection with a certain holding force, without requiring full insertion or tightening.

[0463] During the inverted assembly, the operator lifts the mounting base 300 upwards (towards the roof) from inside the vehicle. As it approaches the second support plate on the roof, the operator adjusts the angle of the mounting base 300, aligning the hook-shaped or engaging portion of the inverted hook-up part 1300 with the pre-set hook-up position on the second support plate (such as the lower edge of the crossbeam or the bracket opening). Then, through an upward movement, possibly accompanied by a slight rotation or lateral sliding, the inverted hook-up part 1300 is moved over the edge of the second support plate and falls beneath it, or its engaging portion engages with the notch on the support plate, thus completing the "hook-up". At this point, part or all of the weight of the mounting base 300 is borne by this hook-up part, allowing it to be stably suspended or supported on the second support plate. This creates extremely convenient conditions for the operator to free up their hands and calmly perform the final tightening operation between the first connecting part 200 and the second connecting part 500.

[0464] Maintaining precise alignment and resisting gravity while lifting the mounting base 300 within a confined and inconvenient overhead space presents a significant challenge. The hook-and-loop design of this embodiment allows the operator to "hook" the mounting base 300 onto the second support plate with a relatively simple and quick action (such as lifting and gently pushing or rotating), instantly achieving self-support and pre-fixation. This completely frees the operator's hands, allowing them to focus on subsequent connection and tightening. It breaks down the complex inversion process into two simple steps: "quick suspension" and "easy tightening," significantly reducing operational difficulty and improving assembly efficiency and success rate.

[0465] When the inverted mounting part 1300 is attached to the second support plate, it typically produces a clear "click" sound, a tactile feedback of a firm fit, or a visual confirmation of alignment. This clear physical feedback allows the operator to confirm successful attachment without visual inspection, solving the assembly confirmation problem in spaces with obstructed vision. Simultaneously, the unique shape of the mounting part and its corresponding attachment structure on the support plate provide physical error prevention, preventing the mounting base 300 from being forcibly installed at the wrong angle or position, thus ensuring the accuracy of pre-assembly from the outset.

[0466] In the attached state, the weight of the mounting base 300 is borne by the second support plate, and there is no additional pressure or misalignment force between it and the interior trim 10 (and the sealing cover 100) due to the need to counteract gravity. This ensures that the first connecting part 200 and the second connecting part 500 are in a natural, interference-free relative position during subsequent alignment and tightening operations. This avoids potential issues such as misaligned threads, deformation of connecting parts, or uneven clamping force that could result from forced connection under initial stress.

[0467] Even after the final "two-way clamping" connection is fully secured, the engagement between the inverted mounting part 1300 and the second support plate remains, forming an additional mechanical safety redundancy. Under the harsh conditions of long-term vehicle vibration and bumps, this mounting part can share some of the dynamic load and form a "main-auxiliary" dual protection with the core clamping connection, further reducing the risk of the entire interface detaching from the roof due to extreme situations (such as accidental loosening of the core connection), thus improving the safety and reliability of the product.

[0468] In other embodiments, refer to Figure 5 , Figure 9 , Figure 10 and Figure 11 As shown, at least one connecting ear 1400 is also provided at intervals on the outer peripheral wall of the mounting base 300, and the connecting ear 1400 is provided with a connecting hole 1410. The connecting hole 1410 is used for a connector to pass through, so as to fasten the mounting base 300 to a first support plate on the side of the interior trim 10 facing the mounting base 300 or a second support plate on the side of the mounting base 300 away from the interior trim 10.

[0469] In this embodiment, the connecting lug 1400 is a boss, wing, or flange structure extending outward from the outer peripheral wall of the mounting base 300, and typically has a flat shape or a shape adapted to a specific mating surface. A connecting hole 1410 is provided through its thickness on each connecting lug 1400. This connecting hole 1410 is a standardized through-hole, its size and shape designed to allow fasteners such as screws, bolts, or rivets to pass through smoothly.

[0470] In specific assembly applications, the function of the connecting hole 1410 is to work in conjunction with the corresponding mounting holes on the vehicle's first support plate (for upright mounting) or second support plate (for inverted mounting). During operation, the mounting base 300 is first pre-aligned with the corresponding support plate via its positioning rib 1100 or inverted positioning / hooking part. Then, the shank of the connector (e.g., a self-tapping screw) is sequentially passed through the connecting hole 1410 on the connecting lug 1400 and the corresponding screw hole or through hole on the support plate. Finally, by tightening the connector (e.g., by screwing in a nut or tapping it into the support plate base), a strong axial clamping force is generated, thereby firmly and immovably mechanically fastening the mounting base 300 to the support plate. This fastening connection constitutes an additional rigid fixing point directly connected to the vehicle body structure, in addition to the core "two-way clamping" connection.

[0471] In this embodiment, the threaded connection (bolt / screw) can generate a large, precisely controllable axial preload. The mounting base 300 is directly locked to the vehicle body support plate (first or second support plate) via the connecting lug 1400 and the connector, forming a rigid metal-to-metal (or high-strength plastic-to-metal) connection. The rigidity and anti-loosening capability of this connection far surpasses that of simple snap-fit ​​or plug-in positioning, ensuring the stability of the power interface device connection.

[0472] In this embodiment, the connecting ear 1400 is fastened, distributing most of the vibration load parallel to the plane (i.e., the shear direction) of the interior trim 10, and firmly "anchoring" the mounting base 300 to the vehicle body, so that the core "two-way clamping" connection mainly bears the clamping force perpendicular to the panel surface. This force distribution optimizes the stress state of the core connection point, reduces the amplitude of the alternating stress it bears, and thus significantly improves the fatigue life and long-term reliability of the entire connection system.

[0473] In the event of a vehicle collision or extreme bumps, components may be subjected to impact loads far exceeding their design specifications. The rigid connection between the connecting lug 1400 and the bolts / screws provides mechanical holding force far exceeding the strength of plastic clips. This provides crucial safety redundancy for the power interface device to remain in place during an accident, preventing it from detaching or being impacted into the passenger compartment, protecting high-voltage or high-temperature electrical connection points, and reducing secondary risks.

[0474] In one embodiment, reference is made to... Figure 5 , Figure 9 , Figure 10 and Figure 11 As shown, there are three connecting ears 1400, and the three connecting ears 1400 are integrally formed around the outer peripheral wall of the mounting base 300.

[0475] In this embodiment, the body of the mounting base 300 and the three connecting ears 1400 are designed within the same mold cavity. Through a single injection molding process (for plastic materials) or die casting (for metal materials), molten material fills the cavity, cools, and solidifies to form a single part comprising both the mounting base 300 body and the three connecting ears 1400. The three connecting ears 1400 are evenly distributed at approximately 120-degree intervals along the circumference of the outer peripheral wall of the mounting base 300, or distributed at non-uniform but optimized intervals depending on the specific shape of the mounting base 300 and its fit with the support plate. Each connecting ear 1400 extends radially outward from the outer peripheral wall of the mounting base 300, with its root smoothly transitioning to the wall surface of the mounting base 300 without any seams or interfaces. Each connecting ear 1400 has a pre-formed connecting hole 1410 for the connector to pass through. Because it is integrally molded, the spatial position, angle, and positional relationship of the three connecting ears 1400 relative to the body of the mounting base 300 are precisely determined and permanently fixed during the manufacturing stage.

[0476] In this embodiment, the three connecting lugs 1400 are evenly distributed on the circumference, forming a stable three-point support plane. When the mounting base 300 is fastened to the support plate by the connectors (bolts), the force system formed by the three fastening points can optimally constrain the translational and rotational degrees of freedom of the mounting base 300 in all directions (axial, radial, and circumferential). In the complex multi-axis vibration environment of a vehicle, the vibration load is evenly distributed on the three fastening points, avoiding stress concentration or axial oscillation that may be caused by single-point or two-point support. This stable fixing method of "three points determining a plane" provides extremely high static and dynamic connection rigidity for the mounting base 300 and even the entire power interface device, making it an ideal mechanical structure to resist long-term vibration and prevent connection loosening.

[0477] Three evenly distributed connecting lugs 1400 transmit and distribute the fastening reaction force from the support plate evenly to the entire circumference of the outer peripheral wall of the mounting base 300 through their roots. This circumferentially uniform load transmission path avoids the wall surface indentation, deformation, or stress whitening that may result from concentrated fastening force acting on a local area of ​​the mounting base 300. The one-piece molded structure ensures that the roots of the connecting lugs 1400 and the body of the mounting base 300 are a continuous material unit, making the force transmission path continuous and without abrupt changes. This further eliminates weak points or stress concentration sources that may be caused by secondary connections (such as welding or screwing), thereby ensuring the structural integrity and dimensional stability of the mounting base 300 under long-term high preload, and fundamentally guaranteeing the stability of the connection.

[0478] In some embodiments, reference is made to Figure 5 , Figure 9 , Figure 10 and Figure 11 As shown, a reinforcing rib 1500 is provided between the connecting ear 1400 and the mounting base 300.

[0479] In this embodiment, the reinforcing rib 1500 is a rib-shaped, plate-shaped, or triangular protrusion connecting the root region of the connecting ear 1400 and the outer peripheral wall of the mounting base 300. Its material is the same as that of the connecting ear 1400 and the mounting base 300 body, and it is typically manufactured simultaneously with both using an integral molding process to form a continuous material monolith. The main location of the reinforcing rib 1500 is the area at the root of the connecting ear 1400 that bears the maximum bending and shear stress, i.e., the starting point where the connecting ear 1400 extends outward from the wall of the mounting base 300. Its shape can be optimized based on stress analysis, for example, designed as a triangular rib extending radially from the root of the connecting ear 1400 to both sides of the wall of the mounting base 300, or a vertical reinforcing plate disposed between the side of the connecting ear 1400 and the wall of the mounting base 300. The thickness, height, and arrangement angle of the reinforcing rib 1500 are designed to maximize the section modulus and bending stiffness of the root of the connecting ear 1400 with minimal material addition.

[0480] In this embodiment, under the complex alternating loads generated by bolt tightening and vehicle vibration, the root of the connecting lug 1400 bears the greatest bending moment. The root of the flat connecting lug 1400 without reinforcing ribs 1500 is a typical stress concentration area, prone to microcracks and even fracture due to stress concentration and material fatigue. In this embodiment, the reinforcing ribs 1500 significantly increase the moment of inertia of this critical area, effectively dispersing the bending stress across a wider material volume and drastically reducing the peak stress. This fundamentally strengthens the weakest link of the connecting lug 1400, enabling it to withstand higher tightening torques and more severe long-term vibration loads, completely eliminating the risk of mechanical fastening failure due to insufficient structural strength of the connecting lug 1400 itself, and serving as the cornerstone of the long-term reliability of the bolted connection.

[0481] Meanwhile, the reinforcing rib 1500 not only strengthens the connecting lug 1400 in the vertical direction, but its connection with the wall of the mounting base 300 also acts like a "triangular brace" or "flying buttress," enhancing the local stiffness of the mounting base 300 wall near the connection point. This effectively suppresses slight indentation or warping deformation of the mounting base 300 wall around the connecting hole 1410 during bolt tightening or under vibration loads. Maintaining the shape stability of the local area of ​​the mounting base 300 is crucial for ensuring that the axis of the connecting hole 1410 is always perpendicular to the fastening plane, maintaining a constant bolt preload, and preventing stress redistribution due to deformation of the base, thereby ensuring the long-lasting accuracy and clamping force of the mechanical connection.

[0482] In other embodiments, refer to Figure 5 , Figure 9 , Figure 10 and Figure 11 As shown, the inverted positioning part 1200 is located between the two connecting ears 1400, and / or, the inverted hook part 1300 is located between the two connecting ears 1400.

[0483] In this embodiment, considering that the outer peripheral wall of the mounting base 300 typically needs to simultaneously arrange connecting ears 1400 for bolt fastening, positioning ribs 1100 for upright mounting, and positioning or hooking parts for inverted mounting, this embodiment optimizes the arrangement of these functional structures to avoid excessive concentration or interference in the circumferential direction. For example, in a certain area of ​​the outer peripheral wall of the mounting base 300, two spaced-apart connecting ears 1400 are provided, forming an arc-shaped area not occupied by other main functional structures. In this embodiment, at least one of the inverted positioning part 1200 (such as an upwardly protruding positioning post) or the inverted hooking part 1300 (such as an upwardly pointing hook) is arranged in the arc-shaped area between these two connecting ears 1400. This means that, from the top view or circumferential unfolded view of the mounting base 300, the inverted component is "nested" between the two connecting ears 1400 in the circumferential direction, and the three (two connecting ears 1400 and one inverted component) are arranged sequentially and spaced apart along the outer periphery of the mounting base 300.

[0484] This layout was determined during the 3D design phase by comprehensively analyzing the spatial location, volume, and functional interference of all functional components, aiming to achieve an integrated design that is compact, interference-free, and has balanced strength.

[0485] In this embodiment, multiple connection and positioning structures need to be integrated within the limited circumferential space of the mounting base 300. This embodiment effectively utilizes the "window" area naturally formed by the spacing between the two connecting ears 1400 by carefully arranging the inverted component between them, avoiding spatial overlap and interference between the inverted component and other protruding structures such as the connecting ears 1400 and positioning ribs 1100 in the radial or circumferential direction. This allows all functional structures to coexist harmoniously within a compact space, maximizing functional integration while ensuring the overall neatness and compactness of the mounting base 300, which is beneficial for arrangement within the narrow installation space of a vehicle.

[0486] Meanwhile, the root of the connecting lug 1400 is a critical area bearing the enormous tensile stress of the bolt, and the surrounding material is under high stress. The inverted components (especially the positioning part) also generate stress at their roots when subjected to loads. The layout strategy of this embodiment avoids placing the inverted components adjacent to a connecting lug 1400, thereby preventing the superposition of stress fields caused by two high-stress root areas being too close, and the potential for localized material overload, deformation, or strength reduction. Placing the inverted components in the "low-stress" interval between the two connecting lugs 1400 spatially separates the force paths for different functions, optimizing the overall stress distribution on the mounting base 300 body and improving structural durability.

[0487] In scenarios involving inverted mounting (such as roof mounting) and the use of bolts for tightening, the operational sequence might be to first attach / position the component, then tighten the bolts. Positioning the inverted component between the two connecting lugs 1400 provides the operator with a clear operating path and field of vision unobstructed by the lugs 1400 during attachment or positioning operations. Simultaneously, when tightening the bolts on the connecting lugs 1400 later, the inverted component does not obstruct the movement of wrenches or screwdrivers. This ergonomic layout simplifies the complex assembly process and reduces operational difficulty.

[0488] It should be noted that the connector 600 in this embodiment can be a power plug, a data cable plug, a data and power integrated plug, a magnetic connector plug, etc.
