[0016] The beneficial effects of this invention are:
[0017] Compared to existing connectors, this invention addresses the harsh environments that vehicles may encounter during operation, such as vibration, moisture, and chemical corrosion. Through a multi-layered independent sealing design at both the front and rear ends, it effectively isolates moisture, dust, and oil from intrusion, ensuring long-term stability and high bandwidth performance of in-vehicle Ethernet signal transmission. This meets the extremely high reliability requirements of intelligent driving and in-vehicle entertainment systems. A dual locking mechanism using elastic clips and an inner sleeve firmly secures the power connection components within the outer cavity, effectively mitigating the impact of continuous vehicle vibration, preventing interface loosening or poor contact, and avoiding signal interruptions caused by vibration, thus improving the overall durability of the in-vehicle network. Integrating fixing, sealing, and locking functions into one unit, the connector boasts a rational structural layout and compact size, making it ideal for deployment and installation in space-constrained areas within the vehicle, providing greater flexibility for the overall vehicle wiring harness layout.
[0018] The shielding shell of the power connector is laser-welded to ensure the airtightness and structural strength of the seams, preventing moisture or contaminants from entering the component through its own seams and achieving an internal shielding seal. Combined with multiple external waterproof seals, this forms a complete protection system. The shielding shell also provides 360° electromagnetic shielding, effectively isolating external electromagnetic interference and preventing internal signal leakage, improving the vehicle's EMC performance, and fundamentally enhancing the long-term reliability of the connector in harsh automotive environments such as humidity and dust.
[0019] The limiting platform on the fixing part cooperates with the abutment plane on the shielded plug to achieve precise axial positioning of the electrical components, preventing displacement during insertion, removal, or vibration. The necked design at the end of the shielded plug facilitates insertion guidance and reduces insertion and removal forces.
[0020] This invention solves three key technical challenges in high-speed Ethernet connections for vehicles: impedance management, electromagnetic shielding, and environmental sealing, thereby improving the overall performance of the connector. Attached Figure Description

[0025] 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.
[0026] like Figures 1-7As shown, in one embodiment of the present invention, a waterproof Ethernet connector is provided, including a housing 1, an inner sleeve 2, a front sealing element 3, a power connection assembly 4, a rear sealing element 5, and a rear fixing element 6. The housing 1 is provided with a fixing part 11, which is used to fix the power connection assembly 4 inside the cavity 12 of the housing 1. The front sealing element 3 and the rear sealing element 5 are respectively provided at the insertion end and the wiring end of the cavity 12. The inner sleeve 2 is provided in the cavity 12 and close to the rear sealing element 5, and is used to cooperate with the fixing part 11 to fix the power connection assembly 4. The fixing part 11 An elastic locking element 111 is provided for engaging and fixing a step of the electrical assembly 4. One end of the inner sleeve 2 covers the elastic locking element 111 to fix it in place, preventing radial movement and keeping the cavity 12 within a fixed cavity. The rear-end fixing element 6 is located at the rear end of the outer shell 1 and fixes the rear-end sealing element 5 within the cavity 12. The electrical assembly 4 is provided with a connecting wire 44, and the rear-end sealing element 5 has a sealing inner ring for passing through the connecting wire 44 and sealingly abutting against the outer diameter of the connecting wire 44. This embodiment addresses the harsh environments that vehicles may encounter during operation, such as vibration, moisture, and chemical corrosion. Through a multi-stage independent sealing design at the front and rear ends, the connector effectively isolates moisture, dust, and oil stains, ensuring long-term stability and high bandwidth performance of the vehicle Ethernet signal transmission, meeting the extremely high reliability requirements of intelligent driving and in-vehicle entertainment systems. The power connection component 4 is securely restrained within the cavity 12 of the outer shell 1 through a double-locking mechanism of elastic clips and inner sleeve 2. This effectively counteracts the impact of continuous vehicle vibration, prevents interface loosening or poor contact, avoids signal interruption due to vibration, and improves the durability of the entire vehicle network. Integrating fixing, sealing, and locking functions into one unit, the structure is rationally laid out and compact, making it ideal for deployment and installation in space-constrained areas within the vehicle, providing greater flexibility for the overall vehicle wiring harness layout.
[0027] See Figures 1-3As shown, the outer casing 1 is provided with a connector 13, and a locking assembly 7 is provided on the side of the outer casing 1 near the connector 13. The locking assembly 7 is used to lock and fix the connector 13 after it is plugged into the object connector. Specifically, the locking assembly 7 includes a locking buckle 71 extending from the end of the connector 13 toward the rear end of the outer casing 1, a sliding groove 72 provided in the outer casing 1, and a locking slider 73 slidably provided on the sliding groove 72. The locking buckle 71 is provided with an elastic pressure groove 711. The locking slider 73 is provided with a locking arm 731, which extends toward the elastic pressure groove 711. The locking latch 71 is provided with a locking positioning block 712 toward the elastic pressure groove 711 for positioning the locking arm 731. The locking slider 73 slides on the slide groove 72. When the locking arm 731 is at the front end of the locking positioning block 712, it presses the locking latch 71 to lock it. When the locking arm 731 is at the rear end of the locking positioning block 712, it unlocks the locking latch 71. In this embodiment, the sliding cooperation design of the locking latch 71 and the locking slider 73, through the movement of the locking arm 731 in the front and rear positions of the locking positioning block 712, achieves clear locking and quick unlocking of the plug-in state. This structure can effectively resist the continuous vibration during vehicle operation, prevent the connector from loosening due to vibration, and ensure the stability of high-speed data transmission of the vehicle Ethernet connection. The operation is intuitive and the feel is clear, which meets the needs of frequent maintenance and plugging / unplugging of vehicle wiring harnesses. At the same time, the overall structure is compact and integrated into the housing 1, without increasing the size of the connector.
[0028] See Figure 2 , Figure 6 As shown, the plug-in end of the outer shell 1 is provided with a plug-in cavity 14, and a sealing groove 141 is provided at the port of the plug-in cavity 14. The front sealing member 3 is embedded in the sealing groove 141. Specifically, a positioning groove 142 is provided on one side of the sealing groove 141, and the front sealing member 3 is provided with a positioning block 31. The positioning block 31 is used to cooperate with the positioning groove 142 to fix the front sealing member 3 in the sealing groove 141. The front sealing member 3 has a sealing inner lip 32 protruding towards the plug-in cavity 14. Multiple sealing inner lips 32 are provided to cooperate with the connector to abut and seal when the connector is inserted. The plug-in end of the power connection assembly 4 extends into the plug-in cavity 14. In this embodiment, through the coordinated design of the sealing groove 141 and the positioning groove 142, the front sealing member 3 can be precisely limited and firmly fixed, preventing it from shifting or twisting during insertion and removal. The layout of multiple sealing inner lips 32 forms multiple redundant sealing barriers. When the connector is inserted, each sealing lip can independently undergo elastic deformation, tightly wrapping the outer wall of the mating end. Even if one sealing lip is slightly worn, the other sealing lips can still function effectively, jointly preventing moisture and dust from entering from the frontmost insertion interface, thus improving the overall protection level.
[0029] See Figure 6As shown, the fixing part 11 includes a front sleeve 112 and a rear sleeve 113. The front sleeve 112 extends toward the insertion cavity 14, and the rear sleeve 113 extends toward the wiring cavity. A connecting ring 114 is provided between the front sleeve 112 and the rear sleeve 113 and integrally formed with the outer shell 1. The elastic buckle 111 is provided on the side of the rear sleeve 113 for fixing the rear side of the power connection assembly 4. The front sleeve 112 is provided with a limiting ring 1121 for limiting the front end of the power connection assembly 4. This embodiment achieves precise axial positioning and reliable radial fixing of the power connection assembly 4. The limiting ring 1121 of the front sleeve 112 ensures that the front end of the power connection assembly 4 will not be over-inserted, while the elastic buckle 111 of the rear sleeve 113 is responsible for fixing the rear end, forming a stable front and rear clamping layout. The split-type but integrated design simplifies the mold structure and reduces production costs, while ensuring the overall structural strength of the fixing part 11, enabling it to withstand the pulling force from the cable and the thrust during insertion, and ensuring that the position of the power connection component 4 within the cavity 12 remains constant.
[0030] See Figure 4 As shown, a reinforcing rib 115 is provided between the rear sleeve 113 and the connecting ring 114. The front end of the inner sleeve 2 is fitted over the rear sleeve 113 to cover the elastic snap-fit member 111. The front end of the inner sleeve 2 abuts against the reinforcing rib 115, and the rear end abuts against the rear sealing member 5 to keep the elastic snap-fit member 111 covered and fixed. This embodiment enhances the rigidity and stability of the connection between the fixing part 11 and the inner sleeve 2. The reinforcing rib 115 improves the bending and torsional strength at the connection between the rear sleeve 113 and the connecting ring 114, preventing deformation under pressure. The front end of the inner sleeve 2 abuts against the reinforcing rib 115, and the rear end abuts against the rear sealing member 5. Through the front and rear clamping installation method, the inner sleeve 2 itself is also firmly positioned in the cavity 12, forming a rigid overall frame. This more effectively covers and constrains the elastic snap-fit member 111, preventing it from springing back and loosening, and also improves the mechanical impact resistance of the entire connector internal structure.
[0031] A fastening rib 121 is provided on the side of the cavity 12 near the fixing part 11. The fastening rib 121 is used to abut against the outer diameter of the inner sleeve 2, so that the inner sleeve 2 is kept centered and fitted around the outer periphery of the fixing part 11. The fixing part 11 is provided with arc-shaped fixing plates 116 on both sides of the elastic fastener 111. The arc-shaped fixing plates 116 on both sides face each other and form a groove for fixing the power connection component 4. The power connection component 4 is provided with a front end boss 411. The arc-shaped fixing plate 116 is provided with a front stop step 1161 to cooperate with the front end boss 411 to fix the front end of the power connection component 4. The elastic fastener 111 is used to fix the rear end of the power connection component 4, so that the power connection component 4 is kept in the groove. This embodiment achieves a firm fixation of the power connection component 4 from all directions. The fastening rib 121 ensures the centered installation of the inner sleeve 2, thereby ensuring a uniform and consistent covering force on the elastic fastener 111. The groove formed by the arc-shaped fixing plate 116 fits tightly with the shape of the power connection component 4. The front stop step 1161 on it cooperates with the front boss 411 of the power connection component 4 to achieve axial limiting; while the elastic buckle 111 at the rear end is axially locked. Through the multiple fixing methods of groove limiting, front step stopping, and rear buckle locking, the stability of the power connection component 4 in three-dimensional space is greatly improved, and it can effectively resist vibration and impact in all directions.
[0032] See Figure 6 As shown, the power connection assembly 4 includes a shielding shell 41, an insulator 42, and a power connection terminal 43. The shielding shell 41 includes a front sleeve 412 and a rear sleeve 413, which are fitted together. The insulator 42 is disposed inside the shielding shell 41 and connects the front sleeve 412 and the rear sleeve 413. The connecting wire 44 is riveted to the tail of the rear sleeve 413 and connected to the power connection terminal 43, which is disposed inside the insulator 42. In this embodiment, the separate shielding shell 41 is connected by fitting and laser welding to form a complete 360° electromagnetic shielding cavity 12, which can effectively isolate external electromagnetic interference and ensure the integrity and low bit error rate of the vehicle Ethernet high-frequency signal transmission. The insulator 42 connects the front and rear sleeves 113, enhancing the overall integrity of the internal structure. The riveting of the connecting wire 44 to the terminal and the design of placing the terminal inside the insulator 42 ensure the reliability of the electrical connection and the safety of insulation, meeting the high reliability requirements of the vehicle electrical system.
[0033] The front sleeve 412 is provided with a shielded plug 414, which extends into the insertion cavity 14 of the outer shell 1. The mating end of the shielded plug 414 is provided with a neck 415, and the port of the neck 415 is provided with an abutment surface. The fixing part 11 is provided with a limiting platform for limiting the front sleeve 412. The front sleeve 412 and the rear sleeve 413 fit together and are fixedly connected at the connection gap by laser welding. In this embodiment, the neck 415 of the shielded plug 414 is designed to facilitate initial alignment with the mating connector and reduce insertion and extraction forces. The abutment surface at the port provides a flat and reliable compression sealing surface for the sealing inner lip 32 of the front sealing element 3, ensuring that the sealing lip can deform uniformly to form an effective seal. The laser welding process ensures high strength and airtightness at the connection of the shielded outer shell 41, further preventing moisture from entering from the gaps in the component itself, while ensuring the continuity of the shielding effect.
[0034] The rear sealing element 5 is provided with multiple sealing lips 51 for abutting against the tail of the cavity 12. The end face of the sealing lip 51 abuts against the inner end face of the rear fixing element 6 to compress the sealing lip 51 towards the inner sleeve 2, forming a seal. The tail of the outer shell 1 is provided with a tail buckle 15, and the rear fixing element 6 is provided with a tail groove 61 to cooperate with the tail buckle 15, fixing the rear fixing element 6 to the tail of the outer shell 1 and pressing the rear sealing element 5 tightly. This embodiment achieves a reliable cable seal with high compression and convenient assembly. When the multiple sealing lips 51 are compressed by the rear fixing element 6, they expand simultaneously in the radial and axial directions, tightly filling all the gaps at the tail of the cavity 12, forming an extremely effective static seal. The cooperation between the tail buckle 15 and the groove provides a tool-free quick locking method, simplifying the on-site installation and maintenance process. This structure ensures adaptability to different wire diameters and can withstand tensile and torsional forces from the cable direction, preventing the seal from failing due to cable movement.
[0035] The inner circumferential surface of the rear sealing element 5 is provided with multiple rear inner lips 52 for abutting against the outer diameter of the connecting wire 44. These multiple rear inner lips 52 are continuously arranged along the axial direction of the connecting wire 44. This embodiment provides multiple dynamic sealing guarantees for the cable interface. The multiple sealing lips 32, continuously arranged along the axial direction, can tightly wrap around and adapt to the outer diameter of the connecting wire 44. When the cable is subjected to bending, vibration, or pulling, these elastic sealing lips can independently move with the cable and maintain sealed contact, forming multiple lines of defense. Even if the outer cable sheath has minor damage or manufacturing tolerances, the multiple sealing lips ensure that moisture does not seep into the connector along the cable surface, improving long-term sealing reliability in vehicle vibration environments.
[0036] 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.
