Description

Technical Field

[0001] This invention relates to the field of electrical connection technology, and in particular to Ethernet cable connectors. Background Technology

[0002] With the rapid development of automotive intelligence and connectivity technologies, the complexity of in-vehicle electronic systems has significantly increased. Advanced Driver Assistance Systems (ADAS), In-vehicle Infotainment Systems (IVI), and in-vehicle Ethernet backbone networks all require simultaneous transmission of high-speed data and provision of stable power, posing unprecedented challenges to in-vehicle connectivity technologies. Traditional solutions typically use separate data connectors and power connectors for wiring and connection, resulting in a large number of wiring harnesses, significant space occupation, complex assembly processes, and increased vehicle weight. Furthermore, in multi-connection-point scenarios, there is a risk of incorrect insertion, which contradicts the trend towards lightweight and integrated automotive development.

[0003] Integrating data and power transmission functions into a single connector is an ideal solution, but it introduces new technical challenges. First, high-current power lines generate strong electromagnetic interference (EMI), severely threatening the transmission integrity of parallel high-speed data signals (such as automotive Ethernet), leading to signal attenuation, increased bit error rate, and directly impacting system functional safety. Second, the harsh automotive environment requires connectors to possess high levels of dust and water resistance (IP) to withstand moisture, splashes, oil contamination, and temperature shocks; integrated design places higher demands on the sealing structure. A single point of failure in a traditional monolithic rear-end seal can simultaneously affect both data and power channels, resulting in poor maintainability. Furthermore, achieving fast, reliable blind mating while ensuring the mating life of both functional interfaces is another obstacle that integrated design must overcome.

[0004] Therefore, there is an urgent need in the field for a highly integrated automotive Ethernet and power connector that can effectively suppress internal electromagnetic interference, has independent and reliable sealing capabilities, and is easy to assemble and maintain, in order to meet the stringent requirements of next-generation smart cars for the performance, reliability, and spatial layout of electrical connection systems.

[0022] Compared to existing Ethernet connectors, this invention integrates signal connection components and power connection components side-by-side within a single housing, achieving integrated data and power transmission in the vehicle system. This saves internal space and aligns with the trend towards miniaturization and lightweighting in automotive electronics. Simultaneously, the signal and power channels are housed in separate first and second cavities, forming physical isolation and effectively preventing electromagnetic interference from the power supply to high-speed data signals, ensuring the stability and reliability of in-vehicle Ethernet communication. A front-end seal within the mating cavity provides a dust and water barrier for the entire connector interface. Independently located first and second rear-end sealing components respectively seal the signal and power lines at their exit points. This "double-sealed" structure provides independent and complete IP protection for both signal and power channels, ensuring long-term safe operation of the connector in automotive environments (such as humidity, splashes, and oil contamination). The signal and power connectors extend and are exposed within a unified mating cavity. This allows the mating parties to complete both data and power connections with a single mating action, greatly simplifying the assembly and maintenance process of automotive wiring harnesses and reducing the risk of incorrect insertion and removal. The integrated interface ensures seamless connectivity and overall stability. The back-end sealing and wiring for signal and power are independent. If a cable or seal for a single function (such as power) fails, targeted maintenance or replacement can be performed without affecting the other function (signal transmission), improving system maintainability. The isolation design also enhances electrical safety. This invention provides a highly integrated, reliably sealed, interference-resistant, and easy-to-assemble automotive Ethernet connector solution, perfectly meeting the stringent requirements of automotive electronics for connector performance, space, and environmental constraints.

Detailed Implementation

[0025] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0027] 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 in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] like Figures 1-11As shown, in one embodiment of the present invention, an Ethernet cable connector is provided, including a housing 1, a signal connection component 2, and a power connection component 3. The housing 1 has a first cavity 11 and a second cavity 12 arranged side by side along the insertion direction. The signal connection component 2 is disposed in the first cavity 11, and the power connection component 3 is disposed in the second cavity 12. The housing 1 has a mating cavity 13 in the insertion direction. The mating cavity 13 is provided with a front end seal 14. The insertion ends of the signal connection component 2 and the power connection component 3 both extend and are exposed outside the mating cavity 13. A first rear end seal component 4 is provided at the tail of the first cavity 11, and a second rear end seal component 5 is provided at the tail of the second cavity 12. The first rear end seal component 4 is used to seal and fix the signal connection line 6 of the signal connection component 2, and the second rear end seal component 5 is used to seal and fix the power connection line 7 of the power connection component 3. This embodiment integrates the signal connection component 2 and the power connection component 3 side-by-side within a single housing 1, achieving integrated connection for data and power transmission in the vehicle system. This saves internal space and aligns with the trend of miniaturization and lightweighting in automotive electronics. Simultaneously, the signal and power channels are located in separate first cavities 11 and second cavities 12, forming physical isolation. This effectively avoids electromagnetic interference from the power supply to high-speed data signals, ensuring the stability and reliability of in-vehicle Ethernet communication. A front-end seal 14 is provided in the mating cavity 13, creating a front-end dust and water barrier for the entire connector interface. The independently located first and second rear-end sealing components 4 and 5 respectively seal the signal and power lines at their exit points. This "double-sealed" structure provides independent and complete IP protection for the signal and power channels, ensuring long-term safe operation of the connector in automotive environments (such as humidity, splashes, and oil contamination). The signal and power connectors extend and are exposed within the unified mating cavity 13. This design allows for simultaneous data and power connections with a single mating action, significantly simplifying the assembly and maintenance process of automotive wiring harnesses and reducing the risk of incorrect insertions and removals. The integrated interface also ensures seamless connection and overall stability. The signal and power back-end seals and wiring are independent. If a cable or seal for a single function (such as power) fails, targeted maintenance or replacement can be performed without affecting the other function (signal transmission), improving system maintainability. The isolation design also enhances electrical safety. This embodiment provides a highly integrated, reliably sealed, interference-resistant, and easy-to-assemble automotive Ethernet connector solution, perfectly meeting the stringent requirements of automotive electronics for connector performance, space, and environmental constraints.

[0029] Figures 2-5 as well as Figure 11As shown, the outer casing 1 is provided with a mounting platform 15, which extends to the mating cavity 13. The front sealing member 14 is disposed on the outer periphery of the mounting platform 15. The first cavity 11 and the second cavity 12 both extend to the end face of the mounting platform 15. The mounting platform 15 is provided with a fixing slot 151 on the outer periphery of the first cavity 11. The signal connection component 2 is provided with a mating connector 21, which is provided with pins 211. The pins 211 are inserted into the fixing slot 151. The mating connector 21 is provided with a plug sleeve 212 for use as a plug when the signal connection component 2 is mated. In this embodiment, by setting the mounting platform 15, a flat mounting reference surface is provided for the front sealing member 14 and the mating connector 21, ensuring uniform sealing and accurate positioning of the plug. The plug-in design of the fixed slot 151 and the pin 211 allows the signal connection component 2, which integrates the plug sleeve 212, to be quickly assembled and replaced as an independent module (plug connector 21), greatly simplifying the production process and facilitating after-sales maintenance, thus realizing the modularity and easy maintenance of the signal interface.

[0030] The mounting platform 15 is located below the first cavity 11 and the fixing slot 151, and a support plate 152 is provided. The support plate 152 extends towards the insertion direction. The mating connector 21 is provided with a panel 213, one side of which is in contact with the mounting platform 15. The pins 211 and the insertion sleeves 212 are respectively provided on the two sides of the panel 213. The panel 213 is provided with a through groove for the support plate 152 to pass through. One side of the support plate 152 abuts against the insertion sleeve 212 to form a plug. In this embodiment, by adding an extended support plate 152 and abutting against the insertion sleeve 212 of the mating connector 21, a rigid mating guide structure is formed. This provides lower support and a precise guide path for the mating plug, effectively preventing connector damage caused by uneven force or misalignment during insertion. The through groove on the panel 213 avoids the support plate 152, achieving compact integration of the structure and ensuring the stability and reliability of the entire component after installation.

[0031] A fixing buckle 153 is provided in the fixing slot 151, and a fixing groove 214 is provided in the plug 211. The plug 211 is inserted into the fixing slot 151 and engages with the fixing buckle 153 through the fixing groove 214, so that the plug-in connector 21 is fixed on the mounting platform 15. In this embodiment, the mechanical locking of the plug-in connector 21 on the mounting platform 15 is achieved through the engaging structure of the fixing buckle 153 and the fixing groove 214. The assembly action is simple and quick (just insert it), with a clear feel, which is conducive to improving the automation level and assembly efficiency of the production line. At the same time, the buckle connection has good vibration resistance and can effectively prevent loosening in the vehicle vibration environment.

[0032] See Figure 11 As shown, the fixing slot 214 includes an insertion section 2141, a first fixing section 2142, and a second fixing section 2143 arranged sequentially. During assembly, the fixing buckle 153 passes through the insertion section 2141 and the first fixing section 2142 sequentially until it is inserted into the second fixing section 2143 for locking and fixing. In this embodiment, the fixing slot 214 is designed as a multi-segment, which, together with the fixing buckle 153, realizes a "three-segment" assembly process with error prevention and confirmation functions. The insertion section 2141 provides smooth insertion, the first fixing section 2142 generates an initial engagement feel and plays a role in preventing backflow, and finally, when it is locked into the second fixing section 2143, it generates a clear sense of completion and maximum locking force. This improves the assembly experience and ensures the reliability of the connector in harsh automotive environments.

[0033] See Figures 4-5 As shown, the first cavity 11 is provided with a power-connecting buckle 111 and a power-connecting limiting platform 112. The power-connecting buckle 111 and the power-connecting limiting platform 112 form a fixed power-connecting position. The signal connection assembly 2 includes a shielding sleeve 22, an insulator 23, and a signal terminal 24. The shielding sleeve 22 covers the outside of the insulator 23, and the signal terminal 24 is disposed inside the insulator 23. The shielding sleeve 22 is provided with a front stop protrusion 221 and a rear stop step 222. The front stop protrusion 221 is used to abut against the power-connecting limiting platform 112, and the rear stop step 222 is used to cooperate with the power-connecting buckle 111 so that the signal power-connecting assembly is held in the fixed power-connecting position. The power-connecting buckle 111 is an elastic buckle. In this embodiment, the connection fixing position formed by the connection buckle 111 and the connection limiting platform 112, along with the front stop boss 221 and the rear stop step 222 on the shielding sleeve 22, together constitute a precise bidirectional axial limit for the signal connection component 2. The elastic buckle design allows the component to be easily inserted and self-locked, while providing continuous holding force, effectively preventing the signal terminal 24 from moving back and forth during insertion, removal, or vibration, ensuring the stability of the electrical connection point and guaranteeing the transmission quality of high-speed data signals.

[0034] The shielding sleeve 22 is provided with a rear sleeve 223. The rear sleeve 223 is used to cover and fix the outer sheath of the signal connecting cable 6 by riveting. The signal connecting cable 6 is provided with a wire clamp 61 to cover the shielding inner core inside the rear sleeve 223. The inner core of the signal connecting cable 6 extends to the insulator 23 and connects to the signal terminal 24. In this embodiment, the outer sheath of the signal connecting cable 6 is covered and fixed inside the rear sleeve 223 by riveting, and the shielding inner core is treated by the wire clamp 61, which achieves a robust mechanical connection and continuous 360° electromagnetic shielding between the cable and the connector. It can withstand greater cable tension and torque, meet the reliability requirements of automotive wiring harnesses, and at the same time ensure shielding effectiveness, preventing high-speed Ethernet signals from being affected by external electromagnetic interference or radiating noise.

[0035] The first cavity 11 has a sealing step 113 at its tail. The first rear sealing assembly 4 includes a first rear sealing member 41 and a first sealing fixing member 42. The first rear sealing member 41 is located at the tail of the first cavity 11 and abuts against the sealing step 113 on one side. The first sealing fixing member 42 is used to fix the first rear sealing member 41 so that the sealing lip of the first rear sealing member 41 abuts against the inner wall of the first cavity 11 and the end face abuts against the sealing step 113. The sealing lip of the first rear sealing member 41 has multiple layers. The inner circumference of the first rear sealing member 41 has a sealing perforation for sealing and passing through the signal connection line 6 of the signal connection assembly 2. In this embodiment, multiple seals are constructed at the tail of the first cavity 11 through the combination of the sealing step 113, the first rear sealing member 41, and the first sealing fixing member 42. The multiple sealing lip is interference-fitted with the inner wall of the cavity to provide a reliable radial seal; the end face abuts against the sealing step 113 to provide an axial seal. The sealing perforation tightly wraps around the cable to prevent moisture from seeping in along the cable. It provides a high level of IP protection for the signal channel, ensuring stable operation in vehicle environments with high humidity and the risk of water splashes.

[0036] See Figure 6 , Figure 9 As shown, the power connection assembly 3 includes a terminal fixing member 31, a mating fixing member 32, and a power terminal 33. The terminal fixing member 31 is disposed within the second cavity 12. The mating fixing member 32 is disposed at the insertion end of the outer shell 1 and fixes the terminal fixing member 31 to one end of the second cavity 12. The other end of the terminal fixing member 31 is provided with a fixing buckle 153 that engages within the second cavity 12. One end of the terminal fixing member 31 extends to the outside of the outer shell 1 and has a fixing groove 214 on the side near the second cavity 12. The mating fixing member 32 engages with the fixing groove 214 to prevent the terminal fixing member 31 from moving axially within the second cavity 12. The power terminal 33 is disposed within the terminal fixing member 31. In this embodiment, the power connection assembly 3 is designed as a modular structure composed of the terminal fixing member 31, the mating fixing member 32, and the power terminal 33. By using a dual fixing method—the fixing buckle 153 engaging with the cavity and the fixing member 32 engaging with the fixing slot 214—the terminal fixing member 31 is firmly fixed in the second cavity 12, effectively resisting the large axial force generated when the power terminal 33 is inserted or removed, preventing it from loosening and moving back, and ensuring the reliability and safety of the power connection.

[0037] The second rear-end sealing assembly 5 includes a second tail seal 51 and a second sealing fastener 52. The second tail seal 51 is disposed in the second cavity 12, with one end abutting against the terminal fastener 31 and the other end pressed and fixed by the second sealing fastener 52. In this embodiment, the second rear-end sealing assembly 5 employs a compression sealing principle. The second sealing fastener 52 presses the second tail seal 51 between the terminal fastener 31 and the cavity, causing it to elastically deform and thus tightly fill all assembly gaps, achieving a reliable static seal. This effectively prevents moisture and contaminants from entering the second cavity 12 from the power cord outlet, providing necessary environmental protection for power connection.

[0038] The terminal fixing member 31 includes a plug-in portion 311, a front end portion 312, and a rear end portion 313. The outer diameter of the rear end portion 313 is larger than that of the front end portion 312. The second cavity 12 is provided with a front cavity 121 and a rear cavity 122. The front end portion 312 is located in the front cavity 121, and the rear end portion 313 is located in the rear cavity 122. The fixing slot 214 is disposed between the plug-in portion 311 and the front end portion 312. In this embodiment, by designing the terminal fixing member 31 as a stepped structure (plug-in portion 311, front end portion 312, rear end portion 313) and cooperating with the correspondingly shaped second cavity 12 (front cavity 121, rear cavity 122), precise axial positioning and effective radial support are achieved. The larger outer diameter of the rear end portion 313 provides a larger contact area, enhancing stability. The fixing slot 214 is located in the structural transition area, with a reasonable mechanical design, allowing the locking force of the mating fixing member 32 to be evenly transmitted, avoiding stress concentration.

[0039] The plug portion 311 is provided with a terminal fixing groove 3111, and the power terminal 33 is disposed in the terminal fixing groove 3111 for inserting the pin of the target connector. The plug portion 311 is provided with a terminal retaining groove 3112, and the power terminal 33 is provided with a terminal latch 331. The terminal latch 331 is used to cooperate with the terminal retaining groove 3112 to fix the power terminal 33 in the terminal fixing groove 3111. In this embodiment, the terminal fixing groove 3111 provided in the plug portion 311 provides precise accommodation and positioning space for the power terminal 33. The cooperation between the terminal latch 331 and the terminal retaining groove 3112 realizes the reliable locking of the power terminal 33 in its fixing groove, preventing it from shifting or falling off when subjected to the insertion force of the pin or vibration, thus ensuring the stability of the power contact and the current carrying capacity.

[0040] Multiple terminal fixing slots 3111 are provided, and each terminal fixing slot 3111 contains a power terminal 33, one end of which is riveted to a power connection wire 7. This embodiment allows for the installation of multiple power terminals 33 by providing multiple terminal fixing slots 3111 on a single terminal fixing member 31, thus achieving centralized connection of multi-core power cables. This meets the increasing power demands of automotive equipment, supports higher current transmission, maintains the compactness of the connector structure, and simplifies the assembly process of multiple power cables.

[0041] An insertion guide hole 3113 is provided at the port of the terminal fixing groove 3111. A terminal limiting platform 3114 is formed on the outer periphery of the insertion guide hole 3113 to limit the power terminal 33 within the terminal fixing groove 3111. An inlet ramp is provided at the end of the insertion guide hole 3113. In this embodiment, the insertion guide hole 3113 and the inlet ramp provided at the port of the terminal fixing groove 3111 can guide the mating pin to easily and accurately align and insert into the power terminal 33, avoiding damage or deformation of the pin head due to bumping against the edge of the terminal port. The terminal limiting platform 3114 ensures that the power terminal 33 is accurately limited to the designed depth, ensuring the correct contact position between it and the pin.

[0042] The fixing component 32 is equipped with a fixing pin 321, which has a pin clip 322. The fixing pin 321 is used to engage with the fixing slot 214, and the pin clip 322 secures it in place, thus fixing the terminal fixing component 31 within the second cavity 12. This embodiment provides an efficient locking mechanism through the engagement of the fixing pin 321 and its pin clip 322 with the fixing slot 214. The structure is easy to assemble; a simple press confirms the engagement with a click, enabling rapid installation. The clip connection provides a stable holding force, ensuring that the terminal fixing component 31 will not move axially under vehicle vibration conditions, guaranteeing the long-term reliability of the power connection.

[0043] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
