[0002] Ethernet is the most common computer network in the real world, widely used across various industries. With technological advancements, the realization of connected vehicles (IoV) technologies such as assisted driving and autonomous driving requires the construction of an Ethernet-based control network. This requires a large number of Ethernet switches and connectors with Ethernet interfaces, leading to the emergence of automotive Ethernet connectors. These connectors are used to transmit data processing information flows between various modules in the vehicle body, offering high data transmission rates, low electromagnetic radiation, and low power consumption.

[0003] Current Ethernet connectors include board-side connectors soldered to circuit boards and line-side connectors that adapt to and connect with the board-side connectors, such as Figure 1 As shown, the board-end connector includes a shielding shell made of metal material, a plastic shell sleeved on the outside of a portion of the shielding shell, and a terminal assembly installed inside the shielding shell, wherein the shielding shell and the terminal assembly are welded to the circuit board, and a mutually cooperating snap-fit ​​structure is provided between the inner wall of the plastic shell and the outer wall of the shielding shell to realize a detachable connection between the two. However, when this structural setting is in use, since the plastic shell is suspended relative to the circuit board, when the end of the plastic shell away from the shielding shell is subjected to force, it is easy to cause the connection between the plastic shell and the shielding shell to separate, and then cause the end of the plastic shell away from the shielding shell to fall down, which will at least affect the smooth insertion of the line-end connector, and at worst cause damage to the board-end connector.

The shielding shell 10 and the terminal assembly 30 are respectively welded to the circuit board 1, wherein the two ends of the terminal assembly 30 are respectively conductively connected to the terminals in the line-end connector and the circuit board 1 to realize the transmission of Ethernet signals. The shielding shell 10 is conductively connected to the circuit board 1 to achieve effective shielding of the signal transmission loop and ensure the stability of signal transmission.

[0031] like Figure 2-Figure 4 As shown, the shielding shell 10 is perpendicular to the two side walls of the circuit board 1, and at least one side wall is provided with a receiving groove 101 with an entrance facing the plastic shell 20.
