[0002] With the rapid development of automotive intelligence and connectivity, in-vehicle Ethernet technology has become crucial for achieving high-speed data transmission within vehicles. As a key component, the performance of the in-vehicle Ethernet connector directly impacts the stability and reliability of the entire vehicle network system.

[0003] Existing automotive Ethernet connectors suffer from several structural instabilities. Firstly, vehicles encounter complex road conditions and severe vibrations during operation. Existing connectors often struggle to withstand these vibrations, leading to loosening of internal electrical components. This can cause signal transmission interruptions or instability, affecting the normal operation of various intelligent vehicle functions, such as autonomous driving assistance systems and in-vehicle entertainment systems. Secondly, existing automotive Ethernet connectors are not manufactured with sufficient precision, resulting in loose fits between components. This can lead to component displacement over long-term use, impacting the quality of the electrical connection. Furthermore, existing connectors lack adequate protective capabilities, failing to effectively resist the intrusion of dust, moisture, and other external factors, which can damage electrical components and further reduce the connector's stability and lifespan.

[0004] Therefore, in order to meet the automotive industry's demand for high-speed and stable data transmission, improving the structural stability of automotive Ethernet connectors is particularly important. Utility Model Content

[0005] To address the aforementioned issues, this invention improves the performance and reliability of automotive Ethernet connectors, and provides a power connection fixing structure and Ethernet cable terminal connector with promising application prospects.

The shell is provided with a cavity. The power-connecting element includes a power-connecting sleeve, an insulator, a power-connecting terminal, and a connecting wire. The power-connecting sleeve includes a front sleeve and a rear sleeve, which are riveted together. The insulator is disposed inside the front sleeve, and the power-connecting terminal is disposed inside the insulator. The connecting wire is disposed on the rear sleeve and electrically connected to the power-connecting terminal. The front sleeve is provided with a front stop and a rear stop. The cavity is provided with a limiting step and a limiting buckle. The limiting step is used to abut the front stop, and the limiting buckle is used to abut the rear stop, so as to fix the front sleeve in the cavity.

[0007] A further improvement to the above solution is that a plug-in latch and a latch slide groove are provided on one side of the outer shell. A locking element is slidably disposed on the latch slide groove. The plug-in latch extends from the plug-in end of the outer shell toward the latch slide groove. The locking element is provided with a pressing part and a locking part. The pressing part extends toward the plug-in latch, and the locking part extends to the bottom of the plug-in latch to support the plug-in latch and keep the plug-in latch in a locked state.

[0008] A further improvement to the above scheme is that the cavity includes a plug-in cavity, a fixed cavity, and a wiring cavity connected in sequence, the front end sleeve is disposed in the fixed cavity and extends to the plug-in cavity at one end, and the rear end sleeve extends to the wiring cavity at one end.

[0009] A further improvement to the above solution is that a through groove is provided on one side of the outer shell, one end of the through groove is connected to the fixing cavity, and the limiting buckle is provided on one side of the through groove to abut the rear end.

[0010] A further improvement to the above scheme is that the insertion end of the front sleeve is provided with a neck, the neck is used to limit the end of the insulator, and contact springs are provided on both sides of the insertion end.

[0011] A further improvement to the above solution is that the rear sleeve includes an insertion part, a retraction part, and a wiring part arranged in sequence. The insertion part is riveted to the front sleeve. An anti-retraction step is provided between the retraction part and the insertion part. The anti-retraction step is flush with the rear end and abuts against the limit buckle.

[0013] A further improvement to the above scheme is that a terminal slot is provided in the insulator, the power-connecting terminal is disposed in the terminal slot, and one end of the terminal slot is used for connecting wire to electrically connect with the power-connecting terminal.

[0014] A further improvement to the above solution is that the power terminal is provided with a power socket and a wire clamp, the power socket is used for the insertion of the terminal of the object connector, and the wire clamp is used for riveting with the connecting wire.

[0015] An Ethernet cable connector includes the aforementioned power-connecting fixing structure.

[0016] The beneficial effects of this utility model are: Compared to existing connector connection structures, this utility model's power connection sleeve uses a riveting method between the front and rear sleeves, resulting in a robust and reliable connection. This effectively ensures the overall stability of the power connection sleeve structure, reduces loosening caused by vibration or external impact, and ensures that the power connection components can still operate normally in the complex vibration environment of an automotive vehicle. The insulator is located inside the front sleeve, and the power connection terminals are housed within the insulator, effectively preventing leakage between the power connection terminals and the front sleeve, thus improving the safety and reliability of the connector. Simultaneously, it avoids electrical faults caused by leakage, ensuring the stable operation of the automotive Ethernet system. The front and rear stop sections of the front sleeve cooperate with the limiting steps and limiting latches of the cavity. The limiting step abuts against the front stop section, and the limiting latch abuts against the rear stop section; this double-limiting design firmly fixes the front sleeve within the cavity. On one hand, it prevents axial displacement of the power connection components during operation, ensuring accurate connection between the power connection terminals and the external power source; on the other hand, it also prevents radial wobbling of the power connection components, further enhancing connection stability. The connecting wire is located on the rear sleeve and electrically connected to the power terminal, making the current transmission path more efficient, reducing resistance, improving conductivity, and lowering power loss. This invention improves the performance and reliability of automotive Ethernet connectors and has promising application prospects. Attached Figure Description

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-7As shown, in one embodiment of this utility model, a power-connecting fixing structure is provided, including a housing 1 and a power-connecting element 2. The housing 1 is provided with a cavity 11. The power-connecting element 2 includes a power-connecting sleeve 21, an insulator 22, a power-connecting terminal 23, and a connecting wire 24. The power-connecting sleeve 21 includes a front sleeve 211 and a rear sleeve 212, which are riveted together. The insulator 22 is disposed inside the front sleeve 211. The power receiving terminal 23 is disposed within the insulator 22, and the connecting wire 24 is disposed on the rear sleeve 212 and electrically connected to the power receiving terminal 23. The front sleeve 211 is provided with a stop front end 2111 and a stop rear end 2112. The cavity 11 is provided with a limiting step 111 and a limiting buckle 112. The limiting step 111 is used to abut against the stop front end 2111, and the limiting buckle 112 is used to abut against the stop rear end 2112, so as to fix the front sleeve 211 in the cavity 11. In this embodiment, the power receiving sleeve 21 is riveted to the rear sleeve 212. The connection method is stable and reliable, which can effectively ensure the stability of the overall structure of the power receiving sleeve 21, reduce loosening caused by vibration or external impact, and ensure that the power receiving element 2 can still work normally in the complex vibration environment of the vehicle. An insulator 22 is disposed within the front sleeve 211, and a power terminal 23 is disposed within the insulator 22. This effectively prevents leakage between the power terminal 23 and the front sleeve 211, improving the safety and reliability of the connector. Simultaneously, it avoids electrical faults caused by leakage, ensuring the stable operation of the vehicle-mounted Ethernet system. The stop front end 2111 and stop rear end 2112 of the front sleeve 211 cooperate with the limiting step 111 and limiting latch 112 of the cavity 11. The limiting step 111 abuts against the stop front end 2111, and the limiting latch 112 abuts against the stop rear end 2112. This double limiting design firmly fixes the front sleeve 211 within the cavity 11. On one hand, it prevents axial displacement of the power connection element 2 during operation, ensuring accurate connection between the power terminal 23 and the external power supply; on the other hand, it also prevents radial wobbling of the power connection element 2, further enhancing connection stability. The connecting wire 24 is disposed on the rear sleeve 212 and conductively connected to the power terminal 23, which makes the current transmission path more reasonable, reduces resistance, improves conductivity, and reduces power loss. This embodiment improves the performance and reliability of the vehicle Ethernet connector and has good application prospects.

[0022] A plug-in latch 12 and a latch groove 13 are provided on one side of the outer casing 1. A locking member 14 is slidably disposed on the latch groove 13. The plug-in latch 12 extends from the plug-in end of the outer casing 1 toward the latch groove 13. The locking member 14 is provided with a pressing part 141 and a locking part 142. The pressing part 141 extends toward the plug-in latch 12, and the locking part 142 extends to the bottom of the plug-in latch 12 to support the plug-in latch 12, so that the plug-in latch 12 remains in a locked state. In this embodiment, the cooperation between the locking member 14 and the plug-in latch 12 greatly enhances the connection reliability of the connector. The locking part 142 of the locking member 14 extends to the bottom of the plug-in latch 12, providing support for it, so that the plug-in latch 12 can stably maintain a locked state. In a vehicle environment, frequent vibrations and bumps occur during vehicle operation. A stable locking structure prevents the connector from accidentally unlocking during vibration, ensuring a secure connection between the electrical fixing structure and external devices. This avoids signal interruptions or transmission instability caused by loose connections, guaranteeing the continuous and stable operation of the vehicle Ethernet system. The sliding design of the locking component 14 on the locking groove 13 makes locking and unlocking operations very convenient. Operators only need to push the pressing part 141 of the locking component 14 to easily achieve the locking and unlocking functions. During connector installation and maintenance, the convenient operation method can improve work efficiency and reduce operation time and labor costs. The stable locking state prevents the electrical fixing structure from accidentally disengaging, avoiding potential electrical safety hazards caused by loose connectors.

[0023] The cavity 11 includes a plug-in cavity 113, a fixing cavity 114, and a wiring cavity 115 connected in sequence. The front sleeve 211 is disposed in the fixing cavity 114 and extends one end to the plug-in cavity 113, and one end of the rear sleeve 212 extends to the wiring cavity 115. Specifically, a through groove 15 is provided on one side of the outer shell 1, one end of which connects to the fixing cavity 114. The limiting buckle 112 is disposed on one side of the through groove 15 to abut against the rear end 2112. In this embodiment, the plug-in cavity 113, the fixing cavity 114, and the wiring cavity 115 connected in sequence form a reasonable and orderly spatial structure. The plug-in cavity 113 provides a dedicated area for the insertion of external devices, facilitating the connection between the power connection fixing structure and the external devices. The fixing cavity 114 is used to house the front sleeve 211, ensuring that the power connection element 2 has a stable fixed position within the outer shell 1. The wiring cavity 115 provides space for the rear sleeve 212 and the connecting wire 24, facilitating the arrangement and connection of the connecting wire 24. This makes the installation and connection of each component clearer and more organized, improving assembly efficiency. The front sleeve 211 is located in the fixed cavity 114 and extends to the insertion cavity 113 at one end, ensuring the front sleeve 211 is firmly fixed within the housing 1 and enabling the electrical terminal 23 to connect well with external equipment within the insertion cavity 113, ensuring stable signal transmission. One end of the rear sleeve 212 extends to the wiring cavity 115, facilitating the conductive connection between the connecting wire 24 and the electrical terminal 23, making the current transmission path more reasonable and reducing interference and loss. The limiting buckle 112 is located on one side of the through groove 15, accurately abutting the stop end 2112 of the front sleeve 211. Together with the limiting step 111 of the cavity 11, it firmly fixes the front sleeve 211 in the cavity 11. The dual limiting method effectively prevents the electrical connection element 2 from moving in the axial and radial directions, thus improving the stability of the electrical connection fixing structure.

[0024] The insertion end of the front sleeve 211 is provided with a neck 2113, which is used to limit the end of the insulator 22. Contact springs 2114 are provided on both sides of the insertion end. In this embodiment, the neck 2113 limits the end of the insulator 22, ensuring that the insulator 22 is accurately and stably positioned within the front sleeve 211. In a vehicle environment, vibrations from vehicle movement may cause internal components to shift. The limiting effect of the neck 2113 prevents the insulator 22 from shifting, ensuring its continuous and stable isolation between the power terminal 23 and the front sleeve 211, avoiding leakage, greatly improving the safety and reliability of the connector, and making the vehicle Ethernet system operate more stably. The contact springs 2114 on both sides of the insertion end play a prominent role. When the connector is connected to an external device, the contact springs 2114 provide good elastic contact. They can adaptively adjust the contact pressure and position with the external device, ensuring a tight and reliable conductive connection between the power terminal 23 and the external device. Even with certain installation errors or slight vibrations, the contact spring 2114 can maintain a stable electrical connection, reduce contact resistance, reduce signal loss during transmission, improve the quality and stability of vehicle Ethernet signal transmission, and ensure accurate and efficient data transmission.

[0025] The rear sleeve 212 includes an insertion part 2121, a retractable part 2122, and a wiring part 2123 arranged sequentially. The insertion part 2121 is riveted to the front sleeve 211. An anti-retraction step 2124 is provided between the retractable part 2122 and the insertion part 2121. The anti-retraction step 2124 is flush with the rear end 2112 and abuts against the limiting buckle 112. Specifically, the wiring part 2123 is provided with a riveting part 2125, which is used to rivet the outside of the connecting wire 24. In this embodiment, the insertion part 2121 is riveted to the front sleeve 211, and the connection method is firm and reliable, which can ensure the stability of the overall structure of the power-connecting sleeve 21. In the complex vibration environment of the vehicle, the riveting structure can effectively resist external forces, prevent the front sleeve 211 and the rear sleeve 212 from separating, ensure the normal operation of the power-connecting element 2, and thus provide a foundation for the stable operation of the vehicle Ethernet system. The anti-retraction step 2124 is positioned between the contraction portion 2122 and the insertion portion 2121, and is flush with the stop rear end 2112 and abuts against the limiting buckle 112. This enhances the fixation of the electrical contact element 2 within the cavity 11 of the housing 1, preventing the electrical contact sleeve 21 from retracting from the cavity 11. Even under strong vibration or impact during vehicle operation, the cooperation between the anti-retraction step 2124 and the limiting buckle 112 ensures that the electrical contact sleeve 21 remains in the correct position, preventing connection failures due to loosening and improving the reliability and stability of the connector. The riveting portion 2125 of the wiring portion 2123 is used to rivet the exterior of the connecting wire 24, ensuring a tight and reliable conductive connection between the connecting wire 24 and the rear sleeve 212. Riveting effectively reduces contact resistance, minimizes power loss, and improves the quality of signal transmission.

[0026] A terminal slot 221 is provided within the insulator 22, and the power-connecting terminal 23 is disposed within the terminal slot 221. One end of the terminal slot 221 is used for electrical connection between the connecting wire 24 and the power-connecting terminal 23. Specifically, the power-connecting terminal 23 is provided with a power-connecting socket 231 and a wire clip 232. The power-connecting socket 231 is used for insertion of the terminal of the target connector, and the wire clip 232 is used for riveting with the connecting wire 24. In this embodiment, the terminal slot 221 provided within the insulator 22 provides a safe and stable installation environment for the power-connecting terminal 23. It effectively prevents the power-connecting terminal 23 from contacting external conductors, avoiding electrical faults such as leakage and short circuits, and ensuring the electrical safety of the vehicle Ethernet system. In the complex vehicle electrical environment, reliable insulation protection can reduce interference and ensure the stability of signal transmission. The power-connecting socket 231 of the power-connecting terminal 23 and the terminal of the target connector can achieve precise mating. When the terminal of the target connector is inserted into the power-connecting socket 231, a good electrical connection can be formed, ensuring the continuity of signal transmission. Meanwhile, the terminal clamp 232 is used to rivet the connecting wire 24. The connection method is firm and reliable, which can resist vibration and bumps during vehicle operation, prevent the connecting wire 24 from loosening, and ensure that the electrical connection between the power terminal 23 and the connecting wire 24 remains stable at all times.

[0027] An Ethernet cable connector, including the aforementioned power-connecting and fixing structure, is adaptable to Ethernet cables and connectors of different specifications and types, facilitating the upgrade and expansion of in-vehicle Ethernet systems. It can be easily connected to various in-vehicle devices, meeting the needs of different vehicles and application scenarios.
