Description

Technical Field

[0001] This application relates to the field of Ethernet connector technology, and more particularly to an automotive Ethernet connector. Background Technology

[0002] Currently, ordinary Ethernet connectors have multiple shortcomings in automotive scenarios: Vehicles frequently encounter continuous interference from bumpy roads and engine vibrations. The plastic clips of ordinary RJ45 connectors are not strong enough and are prone to loosening or even falling off under prolonged vibration, directly causing network interruptions and affecting the transmission of critical information such as autonomous driving perception data and central control commands. Furthermore, the engine compartment and chassis operate under extreme conditions, with temperature fluctuations ranging from -40°C to +125°C, far exceeding the typical tolerance range of -10°C to +60°C for commercial connectors. These extreme temperatures can easily cause the connector materials to age prematurely. Poor contact and poor performance are common problems. The dense concentration of electronic components inside the vehicle, particularly in areas like the dashboard and door panels, makes it difficult for RJ45 modules with transformers to adapt to the lightweight and integrated layout requirements of the vehicle. In-vehicle radar, motors, ECUs, and other devices generate complex electromagnetic interference. Ordinary connectors have weak anti-interference capabilities, easily leading to network signal distortion and even affecting the normal operation of safety-related ECUs such as brakes and steering. Doors and chassis are easily exposed to rain and dust. Ordinary connectors have insufficient sealing performance, and water and dust intrusion can cause component corrosion, short circuits, and connection failures. Utility Model Content

[0019] Please combine Figures 1a to 14This application discloses an automotive Ethernet connector 1, which is used to connect differential lines 2 and transmit and receive data on the differential lines 2. The automotive Ethernet connector 1 includes a detachable plug assembly 10 and a socket assembly 20. The plug assembly 10 includes a signal terminal 11, a first insulator 12, a first cable shield 13, a first metal shield 14, a first housing 15, a first terminal position guarantee 16, and a connector position guarantee 17.

The signal terminal 11 includes a first plug portion 111 and a first connecting portion 112 that are interconnected, and the first connecting portion 112 is used for electrically connecting the differential lines. The first insulator 12 is sleeved on the first plug portion 111. The first cable shield 13 and the first insulator 12 are partially staggered. The first cable shield 13 is fitted over the first insulator 12 at the end near the first connecting portion 112 and outside the first connecting portion 112. The first metal shield 14 is fitted over the first cable shield 13 at the end near the first plug portion 111 and outside the first insulator 12. The first metal shield 14 is electrically connected to the first cable shield 13. The first outer shell 15 is fitted over the first metal shield 14 and the first cable shield 13. The first terminal position guarantee 16 is connected to the first outer shell 15 and is used to lock the signal terminal 11. The connector position guarantee 17 is connected to the first outer shell 15. The signal pin 21 includes a second plug portion 211 and a second connecting portion 212 that are interconnected. The second plug portion 211 mates with the first plug portion 111, and the second connecting portion 212 is used to electrically connect the differential line. The second insulator 22 is fitted over the second plug portion 211. The second cable shield 23 and the second insulator 22 are partially staggered. The second cable shield 23 is fitted onto the end of the second insulator 22 near the second connecting portion 212 and onto the outside of the connecting portion 212. The second metal shield 24 is fitted onto the end of the second cable shield 23 near the second insertion portion 211 and onto the outside of the second insulator 22. The second metal shield 24 is electrically connected to the second cable shield 23 and is circumferentially connected to and electrically connected to the first metal shield 14. The second outer shell 25 is fitted onto the second metal shield 24 and the second cable shield 23. The second outer shell 25 is inserted into the first outer shell 15.

[0020] The automotive Ethernet connector 1 of this application comprehensively improves connector performance in terms of connection stability, anti-interference capability, assembly compatibility, and signal integrity, effectively supporting the reliable operation of automotive Ethernet and providing key hardware guarantees for automotive intelligence and autonomous driving. Firstly, a dual locking mechanism ensures connection stability under vibration, completely solving the problem of loosening in traditional connectors. On one hand, the first and second terminal position guarantee components 26 (TPA) lock the signal terminal 11 and signal pin 21 respectively, effectively limiting the axial and radial displacement of the signal terminal 11 and signal pin 21 during long-term vibration, preventing poor contact caused by the signal terminal 11 / signal pin 21 dislodging from the first insulator 12 / second insulator 22 due to vibration. On the other hand, the connector position guarantee component 17 (CPA) locks the first housing 15 and the second housing 25 after insertion, ensuring that the plug assembly 10 and the socket assembly 20 are fully inserted without the risk of accidental dislodgement, significantly improving shock and vibration resistance and ensuring uninterrupted data transmission for autonomous driving. Secondly, a full-path shielding system enhances electromagnetic compatibility, building a solid barrier for driving safety. The first cable shield 13 is electrically connected to the first metal shield 14, and the second cable shield 23 is electrically connected to the second metal shield 24. Furthermore, after the plug assembly 10 and socket assembly 20 are connected, the first metal shield 14 and the second metal shield 24 are circumferentially connected, forming a complete closed-loop shielding structure. The vehicle-mounted Ethernet connector 1 of this application can comprehensively enclose the signal transmission path, blocking external electromagnetic interference from in-vehicle radar, motors, and other equipment, while also suppressing the connector's own signal radiation. Thirdly, the modular structure balances assembly convenience and spatial adaptability. The plug assembly 10 and socket assembly 20 adopt a detachable plug-in design, which facilitates step-by-step assembly during vehicle production and subsequent maintenance and replacement, reducing maintenance costs. At the same time, the components adopt a compact nested layout with no redundant structure. The first insulator 12 precisely wraps around the first plug part 111 and the second plug part 211. The first cable shielding shell 13 and the second cable shielding shell 23 are partially staggered with the first insulator 12 and the second insulator 22 to compress the axial dimension. The design of the first outer shell 15 and the second outer shell 25 fitting the first cable shielding shell 13 and the second cable shielding shell 23 further simplifies the overall structure and can meet the layout requirements of narrow areas such as the dashboard and doors in the vehicle, which is in line with the "lightweight and dense" layout requirements of the vehicle scenario. Fourth, insulation and shielding work together to improve the integrity of signal transmission.The second insulator 22 is fitted with the second insertion portion 211 of the signal pin 21, and the first insulator 12 is fitted with the first insertion portion 111 of the signal terminal 11. This not only achieves electrical insulation between the signal terminal 11 and the signal pin 21 to prevent short circuit faults, but also ensures the coaxiality and contact accuracy of the signal terminal 11 and the signal pin 21 when they are connected through the fixing effect of the first insulator 12 / second insulator 22. Combined with the full-path shielding system, it can effectively reduce the attenuation and crosstalk of high-speed differential signals during transmission, ensuring the real-time and distortion-free transmission of massive amounts of data such as lidar point clouds and high-definition surround view images, meeting the core requirements of automotive intelligence for high-speed data interaction. Fifth, the structural adaptability supports stable operation under multiple working conditions. The first metal shield 14, the second metal shield 24, the first housing 15, and the second housing 25 possess excellent high and low temperature resistance, maintaining structural rigidity and electrical conductivity within the extreme temperature range of the vehicle. At the same time, the nested connection of each component forms a natural sealing auxiliary structure, preventing water and dust from entering the contact area of ​​the signal terminal 11 and the signal pin 21, avoiding corrosion or short circuits, adapting to the usage requirements of humid and dusty areas such as car doors and chassis, and extending the service life of the vehicle Ethernet connector 1.

[0021] The following is a detailed description of the vehicle-mounted Ethernet connector 11 of this application.

[0022] The plug assembly 10 includes a signal terminal 11, a first plug portion 111 of the signal terminal 11 being tubular, and a second plug portion 211 being inserted into the first plug portion 111 (e.g., Figure 1d (As shown). The first plug portion 111 and the second plug portion 211 form a circumferential wrap-around mating, with a relatively large contact area, more uniform force distribution, and better connection effect. The plug assembly 10 includes an integrally formed first insulator 12, which is sleeved on the outside of the first plug portion 111. A channel 121 is formed inside the first insulator 12, and the signal terminal 11 is sleeved in the channel 121. The channel 121 and the signal terminal 11 (especially the first plug portion 111) form a precise sleeve fit.

[0023] A first opening 113 is provided at the connection point of the first connector 111 and the first connecting part 112. The first opening 113 provides ample operating space for the connection of the first connecting part 112 and the differential line (e.g., welding or crimping), and also facilitates subsequent testing, improving the convenience of production and maintenance. The first insulator 12 forms a first clearance area 122 with a radially penetrating channel 121 corresponding to the first opening 113. The first clearance area 122 can prevent the first insulator 12 from rigidly squeezing the first opening 113, and also provides operating space for the connection of the first connecting part 112 and the differential line. A narrow opening 114 extending towards the first connecting part 112 is provided at the end of the first connector 111 away from the first connecting part 112. The design of the narrow opening 114 makes the end of the first connector 111 form a structure similar to an elastic gripper, which can significantly increase the contact pressure of the first connector 111 on the second connector 211; the first connector 111 can adapt to fit through deformation, avoiding poor contact caused by gaps. The first plug portion 111 is arranged to gradually narrow and then gradually widen in the direction away from the first connecting portion 112. The first plug portion 111 forms a natural guide cone surface, and the second plug portion 211 can quickly slide into the first plug portion 111. The design of the first plug portion 111 gradually widening can avoid excessive compression of the second plug portion 211.

[0024] A wedge-shaped protrusion 115 protrudes from the middle of the outer wall of the first insertion portion 111. The wedge-shaped protrusion 115 gradually expands in the direction toward the first connecting portion 112, and can swing about the side facing away from the first connecting portion 112. A second clearance area 123 is formed in the channel 121 corresponding to the wedge-shaped protrusion 115, and the wall of the second clearance area 123 (through the protruding protrusion) abuts against the wedge-shaped protrusion 115. The wedge-shaped protrusion 115 can be elastically adjusted to further improve the adaptability of the connection. The second clearance area 123 provides swing space for the wedge-shaped protrusion 115. When the plug assembly 10 and the socket assembly 20 are fully inserted, the wedge-shaped protrusion 115 can produce a clear "clunking" or "audible feedback" to provide a clear positioning signal for the assembly personnel (or automated equipment).

[0025] An interference fit protrusion 116 protrudes from the middle of the outer wall of the first insertion part 111. The inner wall of the channel 121 is interference-fitted with the interference fit protrusion 116. Through the interference fit between the interference fit protrusion 116 and the inner wall of the channel 121, the first insertion part 111 can be firmly locked within the channel 121. The interference fit protrusion 116 can be closer to the first connecting part 112 than the wedge-shaped protrusion 115. The position near the first connecting part 112 is the rigid area where the first connecting part 112 connects to the differential line. The rigid fixation of the interference fit protrusion 116 (statically fixed) can prevent stress concentration in the first connecting part 112 due to vibration and prevent fatigue fracture of the solder joint / crimp joint. The position near the first insertion part 111 is the elastic area where it mates with the second insertion part 211. The wedge-shaped protrusion 115 (dynamically compensated) adapts to the mating deviation by swinging. There are two wedge-shaped protrusions 115, which are symmetrically arranged along the axis of the signal terminal 11. There are also two interference protrusions 116, which are located on the same side of the two wedge-shaped protrusions 115. This allows for better circumferential fixing.

[0026] A wedge-shaped connecting portion 124 is formed in the middle of the outer wall of the first insulator 12, and the wedge-shaped connecting portion 124 gradually expands in the direction toward the first connecting portion 112. The plug assembly 10 includes an integrally formed first cable shield 13, which is partially staggered with the first insulator 12. The first cable shield 13 is sleeved on the end of the first insulator 12 near the first connecting portion 112 and on the outside of the first connecting portion 112. A wedge-shaped mating portion 131 is formed at the end of the first cable shield 13 away from the first connecting portion 112 corresponding to the wedge-shaped connecting portion 124. The wedge-shaped mating portion 131 connects to the wedge-shaped connecting portion 124, and the wedge-shaped connecting portion 124 and the mating portion are used to cooperate with each other to prevent the first cable shield 13 from moving toward the first connecting portion 112. As the wedge-shaped connecting portion 124 gradually expands toward the first connecting portion 112, when the first cable shield 13 is assembled in place, the wedge-shaped mating portion 131 will fit tightly against the inclined surface of the wedge-shaped connecting portion 124, forming a reaction force toward the first connecting portion 112. If the first cable shield 13 tends to move toward the first connecting portion 112, the positive pressure of the contact surface between the two will be converted into frictional force, preventing displacement, thus making the locking effect more reliable.

[0027] The first cable shield 13 has two sockets 132 near the first connector 111, arranged along its length. The first metal shield 14 has connection ports 141 corresponding to the two sockets 132. Two gripping arms 142 are symmetrically arranged within each connection port 141. One end of each gripping arm 142 connects to opposite sides of the connection port 141, and the other ends bend towards and insert into the two sockets 132. The two gripping arms 142 are inserted into the two sockets 132, forming two independent conductive paths. Compared to a single-point connection, this effectively reduces contact resistance and prevents shielding failure caused by poor single-point contact due to vibration. The two sockets 132 and the gripping arms 142 form a hook-like lock, preventing the first cable shield 13 and the first metal shield 14 from moving axially and radially. The sockets 132 are cross-shaped, and there is an axial gap between the sockets 132 and the gripping arms 142. The gap provides space for the elastic deformation of the gripper arm 142, which ensures that the gripper arm 142 always stays in contact with the socket 132 when the temperature changes, thus balancing the contradiction between buffering and conduction.

[0028] The first cable shield 13 is formed by enclosing a first sheet-like structure, with the two sides of the first sheet-like structure interlocking. After the first sheet-like structure is enclosed, the two sides form a tight connection through interlocking (such as mortise and tenon joints or hook and groove joints), avoiding contact gaps that may occur with traditional welding or snap-fit ​​connections (gap can lead to electromagnetic leakage). The interlocking two sides form a mechanical lock that prevents the first cable shield 13 from sliding along the cable direction due to vibration, ensuring that it always covers the connection area between the first connecting part 112 and the differential line 2. The small gap at the interlocking point provides a buffer space for the thermal expansion and contraction of the first sheet-like structure, avoiding loosening of the interlocking due to low-temperature contraction or cracking due to high-temperature expansion.

[0029] A limiting block 133 protrudes from the middle of the outer wall of the first cable shield 13. The limiting block 133 is formed by the two interlocking sides of the first sheet-like structure extending outward together. The limiting block 133 and the two sockets 132 are located on opposite sides of the first cable shield 13. A notch 143 is provided at the end of the first metal shield 14 away from the first plug-in portion 111, and the notch 143 is inserted into the limiting block 133. An interference strip 134 protrudes from the middle of the outer wall of the first cable shield 13, and the protrusion height of the interference strip 134 is less than the protrusion height of the limiting block 133. The inner wall of the first metal shield 14 is interference-fitted with the interference strip 134. Based on the above configuration, the connection effect between the first cable shield 13 and the first metal shield 14 is relatively good.

[0030] The first cable shield 13 has two second openings 135, which are located on both sides of the limiting block 133 along the axial direction of the first cable shield 13. The two second openings 135 are formed by the interlocking sides of the first sheet-like structure. The limiting block 133 (which cooperates with the abutment portion 163 of the first terminal position guarantee member 16) is a key structure for locking the signal terminal 11, while the core function of the second openings 135 is to reserve space for the movement and existence of the limiting block 133 and surrounding components, ensuring that their functions do not interfere with each other. The first cable shield 13 needs to adapt to dimensional fluctuations caused by vehicle vibration and temperature changes, and the second openings 135 provide elastic buffer space for the shield by local weakening.

[0031] The first metal shield 14 is formed by the two opposite sides of the second sheet-like structure extending toward each other and fitting together. For the beneficial effects, please refer to the previous description of the first cable shield 13, which will not be repeated here. A cylindrical mating portion 144 is formed at one end of the first metal shield 14 near the first plug-in portion 111. The mating portion 144 is located outside the end of the first insulator 12 near the first plug-in portion 111. The inner wall of the mating portion 144 away from the first connecting portion 112 is fitted onto the outer wall of the second insulator 22 away from the second connecting portion 212. The inner wall of the mating portion 144 is tightly fitted onto the outer wall of the second insulator 22, and simultaneously, the first metal shield 14 and the second metal shield 24 are circumferentially connected, forming a continuous shielding path that intercepts electromagnetic interference outside the mating interface. The mating portion 144 encloses the mating area of ​​the first plug-in portion 111 and the second plug-in portion 211, effectively absorbing electromagnetic radiation generated by small fluctuations in contact impedance in this area. In addition, the sleeve structure of the docking part 144 has a guiding function, and the sleeve design of the docking part 144 improves vibration resistance through radial support.

[0032] The first metal shield 14 has a cutout 145 near the first insertion portion 111. Multiple cutouts 145 are arranged circumferentially around the first metal shield 14. Each cutout 145 contains an elastic conductive sheet 146. One end of the elastic conductive sheet 146 near the first connecting portion 112 is connected to the wall of the cutout 145. The elastic conductive sheet 146 can swing about the side connected to the wall of the cutout 145. The end of the second metal shield 24 away from the second connecting portion 212 is located outside the end of the first metal shield 14 away from the first connecting portion 112. The second metal shield 24 forms a cylindrical mating surface 241 corresponding to the multiple elastic conductive sheets 146. The cylindrical mating surface 241 is in close contact with the multiple elastic conductive sheets 146. The elastic conductive sheets 146 and the cylindrical mating surface 241 form a multi-point encircling contact, resulting in more stable contact resistance. The elastic conductive sheet 146 fits tightly against the cylindrical mating surface 241, effectively preventing electromagnetic waves from leaking or intruding through gaps. Continuous vibrations and sudden impacts during vehicle operation can easily cause relative displacement between the first metal shield 14 and the second metal shield 24; however, the oscillating characteristics of the elastic conductive sheet 146 can maintain stable contact through dynamic adaptation. The elastic conductive sheet 146 can also mitigate structural stress caused by differences in thermal expansion and contraction through flexible compensation.

[0033] The end of the elastic conductive sheet 146 near the first insertion portion 111 protrudes away from the first insulator 12. This end is disc-shaped, while the end away is rod-shaped. The contact quality between the elastic conductive sheet 146 and the cylindrical mating surface 241 directly determines the conductivity of the shielding system, and the disc-shaped protrusion design achieves efficient contact through morphological optimization. The elastic conductive sheet 146 needs to compensate for relative displacement caused by vibration and temperature through oscillation, and the rod-shaped tail structure design makes deformation highly efficient.

[0034] A cylindrical mating groove 151 is formed at one end of the first outer shell 15 near the first insertion part 111. The groove wall of the mating groove 151 is spaced apart from the mating part 144, and the groove wall of the mating groove 151 is spaced apart from the elastic conductive sheet 146. As the outermost protective structure, the core design of the spacing of the mating groove 151 of the first outer shell 15 is to reserve functional movement space for the internal key functional components (matting part 144, elastic conductive sheet 146) to ensure that the components do not interfere with each other.

[0035] A limiting plate 147 protrudes from the middle of the outer wall of the first metal shield 14. A limiting groove 152 is formed in the first outer shell 15 corresponding to the limiting plate 147. The limiting groove 152 is inserted into the limiting plate 147, and the inner wall of the first outer shell 15 abuts against the limiting block 133. Therefore, the connection between the first metal shield 14 and the first outer shell 15 is relatively stable. The limiting plate 147 is formed by the mutually interlocking sides of the second sheet-like structure extending outwards. The first metal shield 14 has two third openings 148, located on both sides of the limiting plate 147 along the axial direction of the first metal shield 14. The two third openings 148 are formed by the mutually interlocking sides of the second sheet-like structure. The beneficial effects of the above arrangement are similar to those of the limiting block 133 and the second opening 135 mentioned above, and will not be repeated here.

[0036] A connecting groove 153 is formed in the middle of the first outer shell 15. The connecting groove 153 includes a main groove 154 and two snap-fit ​​grooves 155. The main groove 154 extends along the length of the first outer shell 15, and the opening of the main groove 154 faces outward. The two snap-fit ​​grooves 155 are symmetrically located on opposite sides of the main groove 154. The two snap-fit ​​grooves 155 are arranged circumferentially along the first outer shell 15 and extend circumferentially in the first outer shell 15. The openings of the two snap-fit ​​grooves 155 face the main groove 154. The first terminal position guarantee member 16 (TPA) includes a middle part 161 and two arc-shaped snap-fit ​​arms 162 symmetrically arranged on opposite sides of the middle part 161. The middle part 161 is inserted into the main groove 154. The two arc-shaped snap-fit ​​arms 162 are respectively inserted into the two snap-fit ​​grooves 155 one by one. The ends of the two arc-shaped snap-fit ​​arms 162 away from the middle part 161 are respectively snapped into the two snap-fit ​​grooves 155. The core function of the TPA is to lock the signal terminal 11 (preventing its axial / radial displacement). The snap-fit ​​structure between the connecting slot 153 and the TPA achieves reliable fixation of the TPA itself through the guidance of the main slot 154 and the locking of the snap-fit ​​slot 155. The middle part 161 is inserted into the main slot 154, restricting the circumferential rotation of the TPA; two arc-shaped snap-fit ​​arms 162 (symmetrically distributed) are respectively inserted into the snap-fit ​​slots 155 on both sides. The end of the arc-shaped snap-fit ​​arm 162 away from the middle part 161 is snapped with the wall of the snap-fit ​​slot 155 to form an axial lock. The symmetrically distributed arc-shaped snap-fit ​​arms 162 cooperate with the snap-fit ​​slots 155 to make the force between the TPA and the first housing 15 evenly distributed circumferentially, avoiding the TPA tilting caused by the loosening of the snap-fit ​​on one side, and ensuring that the locking point of the TPA on the signal terminal 11 is subjected to consistent force. In addition, the shape design of the connecting slot 153 and the TPA naturally has an assembly guiding function, which can reduce the assembly difficulty in the narrow space of the vehicle.

[0037] The portion of the first outer shell 15 that abuts against the limiting block 133 is flush with the side of the limiting block 133 near the first connecting portion 112. The first terminal position guarantee member 16 includes an abutment portion 163, which connects to the portion of the intermediate portion 161 facing the first cable shield shell 13. The side of the abutment portion 163 away from the first connecting portion 112 abuts against the side of the limiting block 133 facing the first connecting portion 112. Terminal locking failure of the vehicle Ethernet connector 1 often stems from the TPA being partially installed (not fully inserted). The limiting design of the abutment portion 163 and the limiting block 133 ensures that the TPA can be 100% in place through mechanical hard constraint.

[0038] The first housing 15 has a recessed area 156 formed on the side opposite to the connecting slot 153. The connector position guarantee 17 (CPA) is fitted into the recess 156. The end of the connector position guarantee 17 away from the first connecting portion 112 is annular and spaced from the first housing 15, while the end of the connector position guarantee 17 near the first connecting portion 112 is seat-shaped and connected to the first housing 15. The core function of the CPA is to lock the first housing 15 and the second housing 25 after insertion (to prevent accidental disengagement), and the connection between the seat-shaped end of the CPA and the first housing 15 provides a stable fixing base. The annular end of the CPA away from the first connecting portion 112 (similar to an elastic claw structure) is the core area for locking with the second housing 25, and its spaced design with the first housing 15 provides elastic buffering capability during the locking process.

[0039] One end of the first housing 15 away from the first connecting portion 112 is inserted into the end of the second housing 25 away from the second connecting portion 212. The mating position 156 gradually narrows in the direction away from the first connecting portion 112. A wedge-shaped insertion groove 251 is formed at the end of the second housing 25 away from the second connecting portion 212. The opening of the wedge-shaped insertion groove 251 faces away from the second connecting portion 212. The end of the mating position 156 away from the first connecting portion 112 and the end of the connector position guarantee 17 away from the first connecting portion 112 are both located in the wedge-shaped insertion groove 251. An opening is provided on the side of the wedge-shaped insertion groove 251 away from the first housing 15, and part of the mating position 156 is exposed in the opening.

[0040] The automotive Ethernet connector 1 faces challenges due to its limited assembly space and the difficulty in aligning the plug assembly 10 and socket assembly 20. The wedge-shaped insertion slot 251 and the tapered mating position 156, guided by their shape, significantly reduce this difficulty. Continuous vibrations and sudden impacts during vehicle operation can easily cause the plug assembly 10 and socket assembly 20 to become axially loose. The tapered mating position 156 and the wedge-shaped insertion slot 251 create a self-locking effect through a wedge tightening mechanism. Partial insertion (not fully engaged) of the automotive Ethernet connector 1 can lead to signal interruption or shielding failure. The open wedge-shaped insertion slot 251 and the exposed design of the mating position 156 ensure proper assembly through both visualization and operability. The nested design of the first housing 15 inserting into the second housing 25, combined with the wedge-shaped mating surface, enhances the overall structural rigidity of the connector while also being compatible with dimensional changes caused by temperature.

[0041] A socket 252 is formed at the end of the second outer shell 25 away from the second connecting portion 212. The end of the socket 252 away from the second connecting portion 212 surrounds the end of the second metal shield 24 away from the second connecting portion 212. The first outer shell 15 is fitted over the socket 252 and connected to the outer wall of the socket 252. The end faces of the first outer shell 15 and the socket 252 away from the second connecting portion 212 are spaced apart. The high-speed signals of automotive Ethernet require extremely high coverage of shielding without dead zones. The nested design of the socket 252 and the first outer shell 15 strengthens the shielding closed loop through physical wrapping and electrical synergy. Continuous vibration and sudden impact of automobiles can easily cause deformation of the mating portion 144 of the plug assembly 10 and the socket assembly 20. The nested design of the first outer shell 15 fitted with the socket 252 enhances the structural rigidity through radial support and overlap.

[0042] The first terminal position guarantee 16 and the second terminal position guarantee 26 are located on opposite sides of the axis of the first housing 15 and the second housing 25. The internal space of the automotive Ethernet connector 1 is extremely valuable, and the TPA needs sufficient structural strength to lock the terminals. The dual-sided distribution design maximizes the use of limited space. When the TPA locks the terminals, it generates a reaction force on the first housing 15 and the second housing 25. The dual-sided distribution can offset the off-center load through symmetrical force distribution, ensuring structural stability. High-speed automotive Ethernet signals are sensitive to electromagnetic interference and physical interference; the dual-sided distribution design reduces risks through functional partitioning. Continuous vibration and sudden impacts in automobiles can easily cause component fatigue due to off-center loads; the dual-sided distribution extends lifespan through symmetrical buffering. Mass production of the automotive Ethernet connector 1 relies on automated equipment; the dual-sided distribution design optimizes the assembly process through separation of operating space.

[0043] The structure of other parts of the signal pin 21 is similar to that of other parts of the signal terminal 11. The structure of the second insulator 22 is similar to that of the first insulator 12. The structure of the second cable shield 23 is similar to that of the first cable shield 13. The structure of other parts of the second metal shield 24 is similar to that of other parts of the first metal shield 14. The structure of the second outer shell 25 is adapted to the structure of the first outer shell 15. The structure of the second terminal position guarantee 26 is similar to that of the first terminal position guarantee 16. Please refer to the attached drawings. The above will not be described in detail again.
