Figure 13 This is a DD cross-sectional view of an automotive Ethernet connector provided in another embodiment of this application. Figure 1-13As shown: This vehicle-mounted Ethernet connector includes a board-end connector 1, a U-shaped semi-enclosed shielding shell 2, pins 3, a wire end shell 4, a bridging clip 5, a wire end connector 6, a rivet shell 7, and terminals 8. The board-end connector 1 includes several pin holes 11 located at the rear, a pair of shielding shell insertion holes 12 located at the top, and a board-end snap-fit ​​interface 13 located on the right side. The pins 3 and shielding shell 2 are connected to the board-end connector 1 through the pin holes 11 and shielding shell insertion holes 12, respectively. The right shell of the shielding shell 2 has a shielding shell notch 21. The wire end shell 4 includes a connector through-hole 41 located on the inner side, a clamping groove 42 located on the side of the connector through-hole 41, and a first wire end shell snap-fit ​​part 43 on the bottom side. It also includes a second wire end shell snap-fit ​​part 44 located on the right side, which is connected to the wire end shell 4 body through a wire end shell right connecting part 45. The bridging clip 5 is inserted into the clamping groove 42. The wire end connector 6 includes... The wire housing 7 includes a terminal hole 61 located at the front end and extending through the rear end, a wire housing fastening part 62 located on the upper end face, and a wire end connector fastening part 63 located on the lower end face; the wire housing 7 includes a wire riveting part 71 on the front side, a wire housing upper fastening part 72 located on the upper rear side, and a wire housing lower fastening part 73 located on the lower rear side; the core wire part of the wire 9 is connected to the terminal 8, the terminal 8 is connected to the wire end connector 6 through the terminal hole 61, the wire riveting part 71 rivets the outer sheath of the wire 9, and the wire housing upper fastening part 63... 2. The wire housing fastening part 62 and the lower wire housing fastening part 73 fasten the wire terminal connector fastening part 63; the wire terminal connector 6 is inserted into the connector through hole 41, and the lower wire housing fastening part 73 fastens the first wire terminal housing fastening part 43; the bridging clip 5 abuts against the side of the rear end of the rivet housing 7; the wire terminal housing 4 is inserted into the board end connector 1, the right connecting part 45 of the wire terminal housing passes through the shielding housing notch 21, the second wire terminal housing fastening part 44 fastens with the board end fastening interface 13, and the pin 3 connects to the terminal 8.

[0037] Specifically, the vehicle Ethernet connector of this application consists of two components—a board-end connector assembly and a wire-end connector assembly. The board-end connector assembly is assembled by inserting the shield shell 2 into the shield shell insertion hole 12 of the board-end connector 1 from top to bottom, and inserting the pin 3 into the pin hole 11. The wire-end connector assembly is assembled by inserting the bridging clip 5 into the clamping groove 42 of the wire-end housing 4. After stripping the wire 9, the core wire is exposed at the end. The core wire is riveted to the terminal 8. Then, the terminal 8 is inserted from the terminal hole 61 at the rear end of the wire-end connector 6 to the front end. The outer sheath of the wire 9 is then riveted to the front side of the riveting shell 7. The upper snap-fit ​​part 72 and the lower snap-fit ​​part 73 on the rear side of the riveting shell 7 are used to fasten the wire-end connector 6. Finally, the wire-end connector 6 is inserted into the wire-end housing 4, thus assembling the assembly.

[0038] It should be noted that, as Figure 13As shown, the bridging clip 5 connects the shielding shell 2 and the rivet shell 7. These three components can be grounded through the grounding part below the shielding shell 2. In addition, compared with the shielding shell without a shield or the simple shielding baffle in the prior art, the U-shaped semi-enclosed shielding shell 2 has significantly enhanced electromagnetic compatibility and electromagnetic interference resistance. Moreover, the shielding shell 2 has a clever design - the right shell has a shielding shell notch 21, which makes the assembly process almost the same as before. After inserting the shielding shell / plate, the wire end shell 4 is inserted. The right connecting part 45 of the wire end shell 4 on the right side will pass through the shielding shell notch 21, avoiding the problem of complicated assembly process caused by structural improvement.

[0039] According to the automotive Ethernet connector of this application, the U-shaped semi-enclosed shielding shell 2 can significantly enhance electromagnetic compatibility and electromagnetic interference resistance while ensuring that the assembly process remains almost unchanged.

[0040] According to one embodiment of this application, the wire connector 6 further includes a plurality of pin holes 64 disposed on the front end face, and the upper surface of the cavity where the pin holes 64 are located has no holes.

[0041] According to one embodiment of this application, observation windows 65 are provided on both sides of the cavity where the pinhole 64 is located.

[0042] Specifically, such as Figure 6 As shown: the pin hole 64 is used to hold the terminal 8 and serves as a window for retracting the terminal 8. In the prior art, the pin hole 64 is located on the upper surface, and the spring in the terminal 8 may slip outwards, potentially damaging the spring when the core wire is pulled out. In this application, the pin hole is located on the front end face, and the upper surface of the cavity is filled without holes, allowing the terminal to be easily held and retracted while avoiding the problem of the spring slipping out.

[0043] According to one embodiment of this application, the wire end connector fastening part 63 is a pair of square bosses; the lower wire housing fastening part 73 is a pair of square holes.

[0044] According to one embodiment of this application, a downward-facing hook 74 is provided below the lower fastening part 73 of the wire housing, and the first wire end housing fastening part 43 fastens the hook 74.

[0045] Specifically, such as Figure 6-7As shown: In the prior art, the wire end connector fastening part 63 is a single boss; the lower wire housing fastening part 73 is a single hole, and the hole is relatively large, with the larger portion used to fasten the first wire end housing fastening part 43. However, during use and during pressing and stretching tests on the product, the applicant found that the structure in the prior art is unstable. The fastening is unstable when the product shakes. For example, if the wire end connector 6 shakes and comes off, the wire end connector fastening part 63 and the lower wire housing fastening part 73 will loosen, making the first wire end housing fastening part 43 unstable. In this application, a fastening hook 74 is provided below the lower wire housing fastening part 73. The fastening hook 74 can prevent the wire end connector fastening part 63 from coming off, ensuring a stable connection between the wire end connector 6 and the wire housing 7.

[0046] According to one embodiment of this application, the fastening part 72 on the wire shell has an inwardly convex structure, so that it is tightly fastened when fastened, and at the same time, the outwardly protruding part is fastened to the fastening part 62 on the wire shell.

[0047] Specifically, such as Figure 2 , 7 As shown: In the prior art, the fastening part 72 on the wire shell is merely an outward protruding structure, used only for fastening with the fastening part 62 on the wire shell. The fastening part 72 itself does not have a locking function, resulting in a loose connection. For example... Figure 7 As shown, in one embodiment of this application, the fastening part 72 on the wire shell is designed as an inwardly convex structure, which can make the fastening part 72 on the wire shell itself securely fastened.

[0048] According to one embodiment of this application, the rear end of the terminal 8 is a semi-enclosed cylindrical structure formed by bending a plane; an upper spring piece 81 is provided at the upper end of the rear end of the terminal 8 facing the front end, and a downwardly protruding semi-circular lower spring piece 82 is provided below the upper spring piece 81.

[0049] According to one embodiment of this application, an upper spring plate 81 has an upper spring plate groove 83 in the middle of its left side plate, and a planar bending structure integral with the upper spring plate 81 is provided above the upper spring plate groove 83; a protective plate 84 is provided on the right side of the upper spring plate 81; and a riveting part 85 connected to the lower spring plate 82 is provided behind the protective plate 84.

[0050] Specifically, such as Figure 8-10 As shown: The rear end of terminal 8 is a semi-enclosed cylindrical structure, which facilitates the forming and assembly of the upper spring piece 81 and the lower spring piece 82. Moreover, in another embodiment, due to the cylindrical structure, the following improvements can be made: 1. The upper spring piece 81, which originally only had a single upward-curving upper end face, is changed to a planar bent structure, making the upper spring piece 81 a planar bent structure with the upper end face and the left end face integrated, which can greatly enhance the strength of the upper spring piece 81 and improve its service life; 2. A protective plate 84 is added to the right end face of the cylindrical shape to protect the upper spring piece 81; 3. The lower spring piece 82 is changed from a two-arm overlapping connection to a riveting reinforcement by the riveting part 85, which improves the strength of the lower spring piece 82.

[0051] According to one embodiment of this application, the front end of the wire end housing 4 is a flat end face, and a housing end face boss 46 is provided below the end face. A clamping groove 42 extends forward to form a clamping groove boss 47. The lengths of the housing end face boss 46 and the clamping groove boss 47 extending forward from the end face are equal.

[0052] Specifically, such as Figure 5 As shown: In the prior art, the wire end shell 4 protrudes while the clamping groove 42 and other components are flat. The end face of this structure is prone to shrinkage and deformation, making it difficult to achieve a flat connection end face when connected to other components. This application changes it to a shell with a flat end face, while the periphery and clamping groove are provided with bosses, which can improve the deformation problem and optimize the product molding quality.

[0053] In addition, the elastic secondary lock on the upper part of the wire end housing 4 can increase the elasticity of the secondary lock arm, making it easier for the secondary lock to engage.

[0054] According to one embodiment of this application, the front or rear end of the left or right shell of the shielding shell 2 is provided with serrations 22.

[0055] Specifically, such as Figure 3 As shown: Adding serrations 22 can play a role in preventing slippage and making the structure more stable.

[0056] The above embodiments are preferred implementations of this application. In addition, this application can be implemented in other ways. Any obvious substitutions without departing from the concept of this application are within the protection scope of this application.
