Figures 1-6As shown, in one embodiment of this utility model, an Ethernet board-end connector is provided, including a housing 1, a plug sleeve 2, a pin fixing part 3, a shielding plate 4, and a power-connecting pin 5. The housing 1 has a plug cavity 11 in the plugging direction, and a tail end 12 is provided at the rear end of the housing 1 opposite to the plug cavity 11. A plug partition 13 is provided between the plug cavity 11 and the tail end 12. The plug sleeve 2 is disposed on the plug partition 13 and extends toward the plug cavity 11. The pin fixing part 3 is disposed on the plug partition 13 and extends toward the tail end 12. The mounting surface of the housing 1 is provided with a shielding slot 16. One end of the shielding slot 16 is connected to the plug cavity 11. There are two shielding slots 16, which are respectively disposed on both sides of the plug cavity 11. There are two shielding plates 4, which are respectively inserted into the two shielding slots 16 and extend to both sides of the plug cavity 11. One end of the power-connecting pin 5 is inserted from the pin fixing part 3 and extends into the plug sleeve 2. This embodiment is used for in-vehicle Ethernet connection. Regarding connection stability, the housing 1 has a plug-in cavity 11 and a tail end 12, which are reasonably separated by a plug-in partition 13. A plug-in sleeve 2 is located on the plug-in partition 13 and extends towards the plug-in cavity 11. One end of the power-connecting pin 5 is inserted from the pin fixing part 3 and extends into the plug-in sleeve 2. This ensures reliable connection between the power-connecting pin 5 and external devices in the complex vibration environment of an in-vehicle environment, effectively preventing loosening or poor contact due to vibration, and guaranteeing the stability and continuity of in-vehicle Ethernet data transmission. For shielding performance, the mounting surface of the housing 1 has two shielding slots 16, with shielding plates 4 inserted into the shielding slots 16 and extending to both sides of the plug-in cavity 11. The design of the shielding plates 4 effectively blocks external electromagnetic interference. Especially in the in-vehicle environment, where numerous electronic devices are present, a complex electromagnetic environment is easily generated. This shielding design prevents electromagnetic interference from affecting Ethernet signal transmission, improving the transmission quality of in-vehicle Ethernet signals and reducing the bit error rate. The pin fixing part 3 is located on the plug-in partition 13 and extends towards the tail end 12, facilitating the installation and fixing of the power-connecting pin 5. Simultaneously, the shielding plate 4 is installed in the shielding slot 16 via insertion, simplifying the installation steps, reducing installation difficulty, and improving production efficiency and subsequent maintenance and replacement operations. This embodiment can adapt to the limited space in a vehicle, achieving a stable and efficient Ethernet electrical connection within a limited space, providing strong support for the stable operation of the vehicle Ethernet system, and promoting the application of vehicle Ethernet technology in the development of automotive intelligence.

[0027] The upper side of the insertion cavity 11 is provided with an upper guide groove 111, and the lower side is provided with a lower guide groove 112. The top of the outer shell 1 is provided with a mating slot 113, one end of which is connected to the upper guide groove 111. Both the upper guide groove 111 and the lower guide groove 112 extend to the insertion partition 13. In this embodiment, the upper guide groove 111 and the lower guide groove 112 extend to the insertion partition 13, providing precise guidance for the mating components. In a vehicle environment, vibrations and bumps during vehicle operation may make connector mating difficult. The guide groove can guide the mating components to be inserted accurately, avoiding poor connection or damage caused by misalignment, thus improving the accuracy and stability of the connection. The mating slot 113 is connected to the upper guide groove 111, further enhancing the reliability of the connection. It can cooperate with the corresponding structure on the mating component to achieve a stable snap-fit. During vehicle operation, this snap-fit ​​structure can prevent the connector from loosening or falling off due to vibration, ensuring the continuity of Ethernet signal transmission.

[0028] The plug-in cavity 11 has shielding grooves 114 on both sides. One end of the shielding slot 16 is connected to the shielding groove 114. The shielding plate 4 is provided with a fixing buckle 41. The shielding plate 4 is secured to the shielding groove 114 by the fixing buckle 41 and is parallel to the plug-in sleeve 2. In this embodiment, from the perspective of shielding performance, the shielding slot 16 is connected to the shielding groove 114, allowing the shielding plate 4 to function more effectively. In the complex vehicle electromagnetic environment, the shielding plate 4 is parallel to the plug-in sleeve 2 and extends to both sides of the plug-in cavity 11, which can shield external electromagnetic interference in all directions, prevent interference signals from affecting Ethernet signal transmission, ensure signal stability and accuracy, reduce bit error rate, and improve the quality of vehicle Ethernet communication. The fixing buckle 41 secures the shielding plate 4 to the shielding groove 114, greatly enhancing the stability of the shielding plate 4 installation. Vibrations and bumps will occur during vehicle operation. A stable installation method can prevent the shielding plate 4 from loosening or shifting, ensuring the continuity and reliability of the shielding effect.

[0029] Both the plug sleeve 2 and the pin fixing part 3 are integrally molded onto the plug partition 13. In this embodiment, from the perspective of structural stability, the integral molding design eliminates the connection gaps between the plug sleeve 2, the pin fixing part 3, and the plug partition 13, enhancing the overall structural strength of the connector. During vehicle operation, frequent vibrations and bumps occur. The integral molding structure better resists external impacts, preventing electrical connection performance from being affected by loose components, ensuring the reliability of the connector in complex automotive environments, and reducing the risk of signal interruption. The integral molding reduces the number of transition points in the signal transmission process, lowering resistance and inductance, making signal transmission more stable and efficient. This helps improve the data transmission rate and quality of automotive Ethernet, reduces signal attenuation and interference, ensures accurate and rapid information exchange between various electronic devices in the vehicle, and improves the overall operating efficiency of the automotive network system.

[0030] A mounting positioning pin 14 is provided at the bottom of the outer casing 1. A support platform 141 is provided at the connection between the mounting positioning pin 14 and the bottom of the outer casing 1. Suspended platforms 15 are provided at both ends of the bottom of the outer casing 1, and the lower surfaces of the suspended platforms 15 are flush with the lower surfaces of the support platforms 141. In this embodiment, the mounting positioning pin 14 provides precise positioning for connector installation. Accurate connector installation is crucial during the assembly of vehicle-mounted equipment. The mounting positioning pin 14 can mate with the corresponding holes at the installation positions, allowing the connector to be installed quickly and accurately in the designated position, improving installation efficiency and avoiding connection problems caused by installation position deviations. The support platform 141, located at the connection between the mounting positioning pin 14 and the bottom of the outer casing 1, enhances the stability of the mounting positioning pin 14. Vibrations and bumps occur during vehicle operation; the support platform 141 can distribute stress, preventing damage or loosening of the mounting positioning pin 14 due to uneven force, ensuring the connector installation is secure.

[0031] The shielding plate 4 is provided with pins 42, which extend towards the bottom of the housing 1. In this embodiment, from the perspective of electromagnetic shielding, the extension of pins 42 to the bottom of the housing 1 further expands the shielding range. In the vehicle environment, there are many complex sources of electromagnetic interference. Pins 42 can better guide external interference signals to the ground, enhancing the shielding protection of internal signals. This makes the shielding plate 4 and the bottom of the housing 1 form a more complete shielding circuit, effectively blocking electromagnetic interference from entering the connector, ensuring the stability and accuracy of Ethernet signals during transmission, reducing the bit error rate, and improving communication quality. The connection of pins 42 to the bottom of the housing 1 is equivalent to adding an additional fixing point to the shielding plate 4. Vibrations and bumps generated during vehicle operation may cause the shielding plate 4 to loosen or shift. The connection of pins 42 to the bottom of the housing 1 can enhance the stability of the shielding plate 4, prevent it from being affected by external forces, and ensure that the connector maintains good shielding performance during long-term use.

[0032] The tail end portion 12 is provided with a pin extension slot 121, and one end of the power-connecting pin 5 extends into the pin extension slot 121. Specifically, there are two power-connecting pins 5, and a pin partition 122 is provided on the pin extension slot 121 to separate the two power-connecting pins 5. The pin partition 122 has inclined surfaces 123 on both sides to guide the two power-connecting pins 5 towards the tail end portion 12 for insertion. In this embodiment, the tail end portion 12 is provided with a pin extension slot 121, and one end of the power-connecting pin 5 extends into this slot, providing a stable placement space for the power-connecting pin 5, preventing the pin from shaking or shifting in the vibration environment of vehicle driving, ensuring the stability of the connection between the pin and other components, and thus maintaining the reliability of the electrical connection. The two power-connecting pins 5 are separated by the pin partition 122, which effectively prevents mutual interference between the pins. In complex vehicle electrical systems, interference between pins may cause signal distortion or transmission errors. The pin partition 122 can reduce interference factors such as electromagnetic coupling, improving the accuracy and quality of Ethernet signal transmission. The beveled surfaces 123 on both sides of the pin separator 122 serve as guides. When the power-connecting pin 5 is inserted towards the tail end 12, the beveled surfaces 123 can guide the pin to be inserted accurately and smoothly into the designated position, reducing the difficulty of insertion and improving assembly efficiency.

[0033] The upper side of the insertion sleeve 2 is provided with an alignment ramp 21 and an alignment groove 22. There are two alignment ramps 21, symmetrically arranged on both sides of the insertion sleeve 2. The alignment groove 22 is centrally located on the upper side of the insertion sleeve 2. In this embodiment, the two symmetrically arranged alignment ramps 21 on both sides of the insertion sleeve 2 provide excellent guidance. During connector insertion, the alignment ramps 21 guide the mating component to accurately insert into the insertion sleeve 2, reducing the difficulty of connection. Even in situations with limited interior space and poor visibility, operators can complete the connection more easily and quickly, improving assembly efficiency. The centrally located alignment groove 22 on the upper side of the insertion sleeve 2 further enhances the accuracy of alignment. It can precisely fit with the protruding structure on the mating component, ensuring the accuracy of the insertion position.

[0034] The power-connecting pin 5 includes a plug-in end 51, a fixed end 52, a bent end 53, and a power-connecting end 54 arranged sequentially. The fixed end 52 is located at the tail end 12, the bent end 53 is bent at a 90-degree angle, and the power-connecting end 54 is used for board-end power connection. The plug-in end 51 extends into the plug-in sleeve 2. In this embodiment, the fixed end 52 of the power-connecting pin 5 is located at the tail end 12, providing stable support and a mounting base for the pin. During vehicle operation, various vibrations and bumps will occur. The stable setting of the fixed end 52 ensures that the pin will not easily loosen or shift, guaranteeing the reliability of the connection between the connector and the tail end 12, thereby maintaining the stability of the electrical connection. The 90-degree bend design of the bent end 53 optimizes the spatial layout of the pin. In the case of limited internal space of the Ethernet board-end connector, the bend allows the pin to better adapt to the internal structure, avoiding interference with other components and improving the internal space utilization of the connector. On the other hand, the 90-degree bend can also change the current conduction path, reduce electromagnetic interference, and help improve the quality of signal transmission.

[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
