[0002] An on-vehicle connection wire harness connector is a type of connector used in automotive electronic systems. It is usually used to connect electronic devices, sensors, control modules, etc. between various parts of a vehicle to achieve functions such as data transmission, signal transmission, and power supply. The on-vehicle connection wire harness connector plays a key role in the automotive electronic system.

[0003] Existing automotive wire harnesses usually include a wire harness, an FPC, and a connector. The wire harness is welded to the FPC, and the FPC is welded to the connector. The connector is connected to external devices or systems to achieve functions such as data transmission, signal transmission, and power supply between the wire harness and the devices or systems.

[0004] The following problems exist in the prior art: The FPC part is usually led out from the glass sandwich layer of the client, and its shape is relatively long, making it difficult to assemble other parts during the processing. At the same time, when a part of the joint assembly is damaged, the welded PFC is not easy to replace, which is not conducive to subsequent maintenance work, and the replacement cost is relatively high. Therefore, there is room for improvement. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the present invention provides a new type of on-vehicle connection wire harness connector to solve the technical problems that the welding process of existing automotive wire harness connectors is relatively cumbersome and complex, and the subsequent maintenance cost is relatively high.

[0006] The present invention is achieved through the following technical solutions:

[0007] A new type of on-vehicle connection wire harness connector includes a bottom plate, an FPC board, a connector, and a wire harness. The connector is fixed on the bottom plate. One end of the FPC board provided with a gold finger is inserted into the connector and electrically connected to the connector. The FPC board and the connector are on the same side of the bottom plate. The FPC board is embedded in the bottom plate. A plurality of groups of wiring ports are arranged on one side edge of the bottom plate. The wire harnesses are respectively welded into each group of the wiring ports, and the wire harnesses are electrically connected to the FPC board through the wiring ports.

[0008] Preferably, a limiting component is arranged on the end faces of the one end of the FPC board provided with the gold fingers that are far away from each other. The limiting component includes a first limiting plate and a limiting block. The first limiting plate is arranged at an angle with the side wall of the FPC board. The limiting block is arranged on the FPC board. An installation groove is arranged on the connector, and the limiting component is inserted into the installation groove.

[0009] Preferably, a waterproof housing is hinged on the connector, and the waterproof housing is hermetically covered on the gold finger area of the FPC board.

[0010] Preferably, a reinforcing plate is arranged on one side of the FPC board, and the reinforcing plate is made of polyimide film material.

[0011] Preferably, a limiting groove is arranged on the bottom plate, the FPC board is clamped in the limiting groove, and the limiting groove is in shape fit with the FPC board.

[0012] Preferably, a second limiting plate protrudes from one end of the limiting groove away from the connector, and the second limiting plate is used to limit the displacement of the FPC board in the vertical direction.

[0013] Preferably, a guiding hole is horizontally opened on the inner wall of one side of the limiting groove away from the connector, a guiding shaft is arranged on one side of the FPC board away from the connector, the guiding shaft is inserted into the guiding hole, and is arranged in shape fit with the guiding hole.

[0014] Preferably, a guiding hole is horizontally opened on the inner wall of one side of the limiting groove away from the connector, a guiding shaft is arranged on one side of the FPC board away from the connector, the guiding shaft is inserted into the guiding hole, and is arranged in shape fit with the guiding hole.

[0015] Preferably, an insulating barrier layer is arranged on the bottom plate, and the insulating barrier layer encloses the electrically connected part therein.

[0016] Preferably, an insulating cushion layer is arranged on the bottom plate, and the insulating cushion layer and the insulating barrier layer form an enclosed space.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. By moving the connector from the FPC end to the wire harness end, the gold finger of the FPC board is directly connected to the connector, eliminating the soldering step and simplifying the installation process; integrating the connector into the wire harness end to form a modular component. This design facilitates quick disassembly and replacement of the wire harness component in case of a fault without complex operations on the FPC part; through the modular design, when a problem occurs in the wire harness or the connector, only the corresponding component needs to be replaced to restore the normal operation of the device, avoiding the high cost and complex process of replacing the entire FPC part;

[0019] 2. Through the setting of the first limit plate and the FPC board, the first limit plate provides a certain frictional force when inserted into the installation groove of the connector, enhancing the fixation between the FPC board and the connector. The limit block is set on the FPC board, and when inserted into the connector, the limit block will be stuck at a specific position in the installation groove, increasing the fixing force of the FPC board in the connector and effectively preventing the FPC board from falling off. The waterproof housing and the connector are connected by a hinge, enabling it to be easily opened and closed, facilitating installation and maintenance, while ensuring that it can be tightly closed during use to prevent moisture from eroding the conduction path and solder joints, maintaining the integrity and electrical performance of the circuit.

[0020] 3. Through the cooperation of the guide shaft and the guide hole, the accurate positioning of the FPC board on the base can be ensured, and the FPC board can be accurately positioned in a specific orientation, thereby ensuring the correct docking of the gold finger part of the FPC board with the pins of the connector. The design of the guide shaft and the guide hole simplifies the installation process of the FPC board. The setting of the fan-shaped wiring port can guide multiple wire harnesses to converge orderly together. This design can help the wire harnesses to be neatly arranged along the fan-shaped curve of the wiring port, avoiding entanglement or intersection during the convergence of the wire harnesses, reducing the bending degree of the wire harnesses. A smaller bending angle can reduce the mechanical stress of the wire harnesses, reducing the risk of wear and breakage and extending the service life of the wire harnesses.

[0037] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0038] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will describe in detail the specific embodiments, structures, features, and their effects of the present invention with reference to the accompanying drawings and preferred embodiments.

[0039] Please refer to Figures 1-6 , a novel on-vehicle connection wire harness connector, which includes a base plate 1, an FPC board 2, a connector 3, and a wire harness 4. The connector 3 is fixed on the base plate 1. One end of the FPC board 2 provided with a gold finger is inserted into the connector 3 and is electrically connected to the connector 3. The FPC board 2 and the connector 3 are located on the same side of the base plate 1. The FPC board 2 is embedded in the base plate 1. A plurality of groups of wiring ports 5 are arranged on one side edge of the base plate 1. The wire harnesses 4 are respectively welded in each group of wiring ports 5. The wire harness 4 is electrically connected to the FPC board 2 through the wiring ports 5.

[0040] Moving the connector 3 from the FPC end to the harness 4 end means that no complex soldering and fixing operations are required when installing the FPC board 2. The gold fingers of the FPC board 2 are directly connected to the connector 3, eliminating the soldering step; no other parts need to be assembled on the FPC part, simplifying the structure of the FPC board 2. Since the position of the FPC part in the client device is usually fixed and difficult to replace, simplifying the installation of the FPC board 2 improves the overall assembly efficiency; moving the connector 3 from the FPC end to the harness 4 end and forming a component with the harness 4 makes it unnecessary to solder the connector 3 at the FPC end, simplifying the installation process; during the installation process with the connector 3, the FPC board 2 is easier to maintain stability when installing the connector 3, reducing the error rate during the installation process; since the position of the FPC part in the client device is usually fixed and difficult to replace, simplifying the installation of the FPC part improves the overall assembly efficiency; integrating the connector 3 into the harness 4 end forms a modular component. This design facilitates quick disassembly and replacement of the harness 4 component in case of a fault without complex operations on the FPC part; through the modular design, when a problem occurs with the harness 4 or the connector 3, only the corresponding component needs to be replaced to restore the normal operation of the device, avoiding the high cost and complex process of replacing the entire FPC part; the modular design of the harness 4 component enables maintenance personnel to complete the replacement operation without professional tools and techniques, further improving the maintenance efficiency and simplicity; at the same time, local replacement of the harness 4 can be quickly achieved, reducing the maintenance cost and time.

[0041] Please refer to Figure 2 and Figure 3, the detachment of the FPC board 2 will cause the interruption of electrical signals and data connections, affecting the stability and reliability of signal transmission. Especially in vehicle-mounted systems, unstable signal transmission may lead to malfunctions of vehicle-mounted devices. At the same time, due to the unstable connection, data loss or errors may occur during data transmission, affecting the normal operation of the vehicle-mounted system. The detachment of important electrical signal connections may cause the vehicle-mounted devices to fail to work properly, or even cause the entire system to crash, affecting the normal operation and driving safety of the vehicle. At the same time, the detached FPC board 2 may come into contact with other metal components, resulting in a short circuit, increasing the risk of faults and safety hazards in the electrical system. In addition, frequent detachment and reconnection will accelerate the wear of the FPC board 2 and the connector 3, shorten their service life, and affect the reliability and durability of the entire wire harness 4 joint. Frequent failures and repairs will bring inconvenience to users, reducing users' satisfaction and trust in the vehicle and vehicle-mounted devices. Based on this, in one embodiment, a limiting component 6 is provided on the end surface of the FPC board 2 where the ends of the gold fingers are far away from each other. The limiting component 6 includes a first limiting plate 61 and a limiting block 62. The first limiting plate 61 is arranged at an angle with the side wall of the FPC board 2. The limiting block 62 is arranged on the FPC board 2. An installation groove 7 is provided on the connector 3, and the limiting component 6 is inserted into the installation groove 7. The first limiting plate 61 is arranged at an angle with the side wall of the FPC board 2. This angle design can provide a certain frictional force when the first limiting plate 61 is inserted into the installation groove 7 of the connector 3, enhancing the fixation between the FPC board 2 and the connector 3. The limiting block 62 is arranged on the FPC board 2, and when inserted into the connector 3, the limiting block 62 will be stuck at a specific position in the installation groove 7, increasing the fixing force of the FPC board 2 in the connector 3. The connector 3 is provided with an installation groove 7 for accommodating the limiting component 6. When the FPC board 2 is inserted into the connector 3, the first limiting plate 61 and the limiting block 62 will be inserted into the installation groove 7, thus playing a role of limiting and fixing. The first limiting plate 61 and the limiting block 62, through their mutual cooperation with the installation groove 7, increase the fixing force of the FPC board 2 in the connector 3, effectively preventing the FPC board 2 from detaching.

[0042] In actual use, the gold finger end of the FPC board 2 is inserted into the connector 3, and the first limiting plate 61 and the limiting block 62 enter the installation groove 7 simultaneously. The limiting block 62 is stuck in the installation groove 7 to restrict the movement of the FPC board 2 and prevent it from falling off easily. The frictional force between the first limiting plate 61 and the installation groove 7 further enhances the fixation of the FPC board 2; the limiting component 6 provides additional physical fixation to ensure that the FPC board 2 will not fall off easily when subjected to external forces or vibrations, improving the connection stability; through the fixation of the limiting component 6, the electrical connection between the FPC board 2 and the connector 3 is ensured to be stable, avoiding the interruption of electrical signals and data transmission caused by falling off; the stable connection reduces the loss or error during data transmission, ensuring the normal operation of the in-vehicle system; the fixation of the limiting component 6 reduces the frequent falling off and reconnection between the FPC board 2 and the connector 3, reduces wear, and extends the service life of the FPC board 2 and the connector 3; due to the more stable connection, the durability and reliability of the overall wire harness 4 connector are also improved; the limiting component 6 ensures that the FPC board 2 will not fall off and come into contact with other metal parts, reducing the short-circuit risk and increasing the safety of the electrical system; the stable connection reduces the electrical faults caused by falling off, ensuring the normal operation and driving safety of the vehicle; the application of the limiting component 6 reduces the faults caused by the falling off of the FPC board 2, reduces the maintenance frequency, and reduces the inconvenience to users; the more stable and reliable connection reduces the occurrence of faults and improves the user's satisfaction with the vehicle and in-vehicle equipment.

[0043] Please refer to Figure 2, during use, if moisture enters the FPC board 2, it will cause a short circuit in the circuit, which may lead to electrical failures and even damage to the connector 3 and the FPC board 2. Moisture will cause oxidation and corrosion of the conductive paths and solder joints on the FPC board 2, affecting the electrical performance and reliability; moisture may cause electrical signal interference between circuits, resulting in unstable signal transmission and affecting the normal operation of the in-vehicle system. Unstable signal transmission may lead to data loss or errors, affecting the reliability of the in-vehicle system; the normal operation of in-vehicle equipment depends on stable signal transmission. Water ingress may cause the equipment to malfunction and affect the normal operation of the vehicle. Frequent circuit failures and damages will increase the frequency of maintenance and repair, increasing the maintenance cost and inconvenience for users. The repair of the FPC board 2 and its connector 3 is relatively complex, and the fault repair process caused by water ingress is more cumbersome and time-consuming; based on this, in one embodiment, a waterproof housing 8 is hingedly provided on the connector 3, and the waterproof housing 8 is hermetically covered on the gold finger area of the FPC board 2. The waterproof housing 8 is connected to the connector 3 by a hinged manner, enabling it to be easily opened and closed, facilitating installation and maintenance, and at the same time ensuring a tight closure during use, providing effective sealing protection; the waterproof housing 8 is made of a material with high density and excellent waterproof performance, such as silicone or rubber, to ensure effective prevention of moisture ingress in various environments; the gold finger area is the electrical connection part between the FPC board 2 and the connector 3. Protecting this area from moisture can effectively guarantee the stability and reliability of the entire electrical connection; the hinged structure enables the waterproof housing 8 to be easily opened and closed, facilitating operation during installation and maintenance, and improving the convenience of use; by sealing the gold finger area, moisture erosion of the conductive paths and solder joints is prevented, maintaining the integrity and electrical performance of the circuit; the protection of the waterproof housing 8 can prevent electrical signal interference caused by moisture, ensuring the stability of signal transmission and the normal operation of the in-vehicle system; avoiding signal instability caused by moisture, thereby reducing data loss or errors and improving the reliability of the in-vehicle system. Preventing moisture from entering the gold finger area can reduce equipment failures caused by moisture, improving the reliability and uptime of in-vehicle equipment; by preventing moisture from corroding the conductive paths and solder joints, the service life of the FPC board 2 and the connector 3 is extended, reducing the need for frequent repairs and replacements; effective waterproof measures can reduce circuit failures caused by moisture, thereby reducing the frequency of maintenance and repair and reducing the maintenance cost for users.

[0044] Please refer to Figure 2 and Figure 4, due to its flexibility, the FPC board 2 is prone to bending or breakage due to mechanical stress during operation and use, resulting in a shortened lifespan of the FPC board 2; the FPC board 2 cannot effectively absorb and disperse external impact forces, and is easily damaged when the vehicle jolts or is subjected to external forces, affecting the reliability of electrical connections; the FPC board 2 may not be able to maintain its physical and chemical properties in a high-temperature environment, and is prone to deformation or damage. Especially in vehicle-mounted systems, such as in the high-temperature environment of the engine compartment, the FPC board 2 is prone to failure; under high-temperature conditions, the connector 3 and other connection components are also affected, which may lead to unstable connections or disconnections, affecting the normal operation of the system; at the same time, lacking high-insulation performance protection, the FPC board 2 is easily affected by electrical interference and short-circuit problems, resulting in a reduced reliability of electrical connections; based on this, in one embodiment, a reinforcing plate 9 is provided on one side of the FPC board 2, and the reinforcing plate 9 is made of polyimide film material. Due to its flexibility, the FPC board 2 may not have sufficient mechanical strength in some cases. The reinforcing plate 9 provides additional support, enhancing the structural strength of the FPC board 2 and avoiding bending or breakage caused by mechanical stress during operation and use; the polyimide film has excellent impact resistance, can effectively absorb and disperse external impact forces, and reduces the risk of damage to the FPC board 2 during use; the polyimide film has excellent high-temperature resistance and can maintain its physical and chemical properties in a high-temperature environment, preventing damage to the FPC board 2 and its connection components caused by high temperature; the heat-resistant characteristics of the reinforcing plate 9 can ensure the stability and reliability of the FPC board 2 and its connection components in a high-temperature working environment (such as in the engine compartment); the high-insulation performance of the polyimide film can prevent electrical interference and short-circuit problems, ensuring the reliability of the electrical connections of the FPC board 2 and improving the electrical performance of the entire wire harness 4 connector; the electrical insulation performance of the reinforcing plate 9 helps to maintain the stability and accuracy of signal transmission, avoiding signal interference and data loss; the polyimide film has excellent chemical corrosion resistance and can resist the erosion of various chemical substances, extending the service life of the FPC board 2 and the wire harness 4 connector; the setting of the reinforcing plate 9 makes the FPC board 2 more stable and easier to operate during installation, reducing the installation difficulty caused by the deformation of the flexible board; the reinforcing plate 9 improves the mechanical strength and durability of the FPC board 2, reducing the need for frequent maintenance due to damage during use, thereby reducing the maintenance cost and time.

[0045] Please refer to Figure 2 and Figure 4, if the FPC board 2 is not accurately aligned with the limiting slot 10 during installation, it may cause the position of the FPC board 2 on the base to be unstable, resulting in slippage; at the same time, the risk of slippage is increased. Vibration and shock in the vehicle environment may cause the FPC board 2 to move from the bottom plate 1, especially if the limiting slot 10 is not designed deep enough or the clamping is not firm enough; in addition, extreme temperature changes may cause material expansion or contraction, affecting the fit between the FPC board 2 and the bottom plate 1, resulting in slippage; extreme temperature changes may cause material expansion or contraction, affecting the fit between the FPC board 2 and the bottom plate 1, resulting in slippage; based on this, in an embodiment, a limiting slot 10 is provided on the bottom plate 1, and the FPC board 2 is clamped in the limiting slot 10, and the shape of the limiting slot 10 matches the shape of the FPC board 2. By matching the shape of the limiting slot 10 with the FPC board 2, the FPC board 2 is firmly clamped on the base, avoiding the movement or offset of the FPC board 2 during installation or operation. This fixation can ensure that the FPC board 2 maintains a stable position during use, thus maintaining the reliability of the electrical connection; there may be vibrations and shocks in the vehicle environment, and the setting of the limiting slot 10 can effectively reduce the influence of these factors on the position of the FPC board 2, avoiding poor connection or disconnection caused by vibration; the design of the limiting slot 10 can help accurately align the FPC board 2 and the connector 3, so that the FPC board 2 can be correctly inserted into the connector 3 during installation. This cooperation reduces the installation error and improves the overall installation accuracy; by fixing the FPC board 2 firmly in the limiting slot 10, the installation process becomes simpler and faster. The installer can quickly place the FPC board 2 into the slot without additional adjustment or alignment operations, thus shortening the installation time; the stable installation position can effectively reduce the influence of mechanical stress on the FPC board 2, avoiding damage or deformation caused by mechanical vibration, collision or external force application; when the FPC board 2 needs to be maintained or replaced, the design of the limiting slot 10 allows the FPC board 2 to be quickly and safely removed from the base, facilitating the maintenance or replacement operation. A good design can also make the replacement process simple and efficient, reducing the equipment downtime; by firmly fixing the FPC board 2 in the limiting slot 10, it is ensured that the gold finger part of the FPC board 2 and the connector 3 maintain good contact, reducing the risk of poor electrical contact and improving the stability and reliability of the connection; the stable installation position also helps to reduce signal interference and noise, maintaining the stability of signal transmission, thus improving the performance of the overall vehicle-mounted system.

[0046] Please refer to Figure 2 and Figure 4, the displacement of the FPC board 2 in the vertical direction may cause poor contact or even complete disconnection between its gold finger part and the connector 3. This will lead to an interruption in the electrical connection, affecting the normal operation of the in-vehicle system, possibly resulting in signal loss, system failures, or the device being unable to operate properly. At the same time, the unrestricted displacement may cause unstable contact between the FPC board 2 and the connector 3 during use, generating electrical interference and signal transmission errors. The instability of signal transmission will affect the performance of the in-vehicle system and the accuracy of data. The free movement of the FPC board 2 in the vertical direction may cause mechanical stress concentration, especially under the action of vibration or shock. Stress concentration will cause deformation, cracks, or other mechanical damages to the FPC board 2, shortening its service life. The FPC board 2 without vertical displacement limitation may be difficult to accurately align with the connector 3 during installation, which will lead to installation errors, increase the difficulty of adjustment and reinstallation, and reduce the installation efficiency. Due to the connection problems caused by the vertical displacement of the FPC board 2, it may trigger faults or instability in the entire in-vehicle system, affecting the functions and driving safety of the vehicle, especially in high-demand application scenarios such as autonomous driving or advanced driver assistance systems. Based on this, in one embodiment, a second limiting plate 11 protrudes from one end of the limiting groove 10 away from the connector 3, and the second limiting plate 11 is used to limit the displacement of the FPC board 2 in the vertical direction. By restricting the displacement of the FPC board 2 in the vertical direction, the second limiting plate 11 prevents the FPC board 2 from generating vertical movement due to mechanical vibration, shock, or other external forces during installation or use. This can ensure that the FPC board 2 always remains in the designed fixed position, avoiding connection problems or damages caused by vertical displacement. The design of the second limiting plate 11 enables the FPC board 2 to be more firmly fixed on the base, preventing the board from moving due to operation, vibration, or external forces, thus ensuring the stability of the electrical connection. A stable installation position helps to maintain good contact between the gold finger part and the connector 3, ensuring the reliability of electrical signal transmission. The second limiting plate 11 helps to accurately align the FPC board 2 and the limiting groove 10 of the base, enabling the FPC board 2 to accurately dock when inserted into the connector 3. This precise alignment reduces installation errors, improves the overall installation accuracy, and thus enhances the performance and reliability of the entire system. By restricting the displacement of the FPC board 2 in the vertical direction, the second limiting plate 11 can reduce the deformation or damage of the board caused by mechanical stress concentration. This design can effectively prevent stress concentration caused by external forces, thereby reducing the risk of mechanical damage to the FPC board 2. The design of the second limiting plate 11 enables the FPC board 2 to be more easily inserted into the limiting groove 10 and fixed in the correct position. This design simplifies the installation process, and installers can quickly and accurately place the FPC board 2 into the base, thus improving the installation efficiency and reducing possible problems during installation.

[0047] Please refer to Figure 2 and Figure 4, the positional change of the FPC board 2 may cause poor contact between the gold fingers and the pins of the connector 3, which will affect the transmission of electrical signals, resulting in unstable or intermittent signal transmission; unstable signal transmission may cause data loss or errors, which is very important for data processing and communication in the in-vehicle system and may lead to abnormal system functions; if the positional change of the FPC board 2 causes inaccurate docking, it may increase the mechanical stress concentration, resulting in deformation or damage of the board material and affecting the durability of the overall structure; uneven mechanical stress may accelerate the wear of the FPC board 2 and the connector 3 and shorten their service life; poor electrical connection may cause signal interference and noise, affecting the stability and performance of the in-vehicle system and resulting in system failures or abnormalities. Based on this, in an embodiment, a guiding hole 12 is horizontally formed on the inner wall of the limiting groove 10 on the side away from the connector 3, and a guiding shaft 13 is provided on the side of the FPC board 2 away from the connector 3. The guiding shaft 13 is inserted into the guiding hole 12 and is arranged in shape matching with the guiding hole 12. The cooperation between the guiding shaft 13 and the guiding hole 12 can ensure the accurate positioning of the FPC board 2 on the base. By inserting the guiding shaft 13 into the guiding hole 12, the FPC board 2 can be accurately positioned in a specific orientation, thus ensuring the correct docking of the gold finger part of the FPC board 2 with the pins of the connector 3. This precise alignment is crucial for the reliability of the electrical connection; the design of the guiding shaft 13 and the guiding hole 12 simplifies the installation process of the FPC board 2. The installer only needs to align the guiding shaft 13 with the guiding hole 12 and insert it, and the FPC board 2 will be automatically positioned in the correct position. This design reduces the adjustment and alignment work during the installation process, reduces the installation error, and improves the installation efficiency; through precise positioning, the cooperation between the guiding shaft 13 and the guiding hole 12 can ensure the stable electrical contact between the gold fingers of the FPC board 2 and the connector 3. This can effectively prevent poor electrical contact caused by inaccurate positioning, thereby improving the stability and reliability of signal transmission; the accurate positioning of the FPC board 2 can avoid mechanical stress concentration caused by incorrect docking. The cooperation between the guiding shaft 13 and the guiding hole 12 can evenly distribute the mechanical stress, reduce the deformation or damage of the FPC board 2 caused by mechanical stress, and improve the durability of the overall structure.

[0048] Please refer to Figure 5 and Figure 6, to facilitate the management of the wire harness 4, all the wires are usually bundled together. During the bundling process, the wire harness 4 will be bent to a certain extent, and the bending will cause wear on the insulation layer or sheath of the wire harness 4, thus exposing the internal wires. At the same time, the worn wire harness 4 is prone to electrical short - circuit or open - circuit problems, reducing its service life; at the same time, excessive bending may cause the wires inside the wire harness 4 to break or have broken filaments, resulting in unstable or interrupted electrical connections. The bent part will concentrate mechanical stress, increasing the risk of wear and breakage of the wire harness 4 in these areas and affecting the overall structural stability of the wire harness 4; based on this, in one embodiment, the horizontal cross - section of the wiring port 5 is fan - shaped, and the end of the wiring port 5 far from the bottom plate 1 is closed. The fan - shaped design of the wiring port 5 can guide multiple wire harnesses 4 to converge orderly. This design can help the wire harness 4 to be neatly arranged along the fan - shaped curve of the wiring port 5, avoiding entanglement or intersection of the wire harness 4 during the convergence process, thus improving the neatness and aesthetics of the overall layout; because the fan - shaped design of the wiring port 5 can reduce the bending degree of the wire harness 4, the bending generated during the convergence of the wire harness 4 is reduced. A smaller bending angle can reduce the mechanical stress of the wire harness 4, reduce the risk of wear and breakage, and extend the service life of the wire harness 4; the fan - shaped design of the wiring port 5 not only helps the orderly convergence of the wire harness 4, but also helps to protect the wire harness 4. Due to the smooth shape and closed - end design of the wiring port 5, the wire harness 4 will not be subjected to excessive external forces, thus reducing physical damage to the wire harness 4; bundling the wire harness 4 together and guiding it through the fan - shaped wiring port 5 can simplify the wiring and installation process of the wire harness 4. The neat layout of the wire harness 4 can reduce the complexity during the installation of the wire harness 4 and improve the installation efficiency; by effectively converging the wire harness 4 and preventing excessive bending of the wire harness 4, the interference between the wire harnesses 4 can be reduced, avoiding mutual extrusion or friction of the wire harnesses 4, and reducing possible electrical interference and signal transmission problems; the orderly arrangement of the wire harness 4 makes subsequent maintenance and repair work more convenient. Maintenance personnel can more easily find and handle specific wire harness 4 problems, reducing the maintenance time and complexity.

The insulating cushion layer 15 can play a certain role in thermal isolation, preventing heat from being conducted from the base plate 1 to the electrically connected parts and protecting sensitive components from overheating. Effective thermal management can extend the service life of the device and ensure its reliability in a high-temperature environment. The insulating cushion layer 15 provides physical protection for the electrically connected parts, preventing the intrusion of external environments such as dust, moisture, and chemicals into the connection parts. This protection can reduce the risk of failures caused by environmental factors and improve the durability and stability of the device. In a vehicle-mounted environment, the device is usually subject to vibration and shock. The insulating cushion layer 15 can play a role in shock absorption, reducing the impact of vibration on the electrical connection. This helps to maintain the stability of the connection and reduce the contact failure or damage caused by vibration.
