[0020] Please refer to Figures 1 to 4 As shown, a preferred embodiment of the present utility model discloses an outer conductor 100 for use in a vehicle-mounted Ethernet connector (not shown). The outer conductor 100 is for receiving one or more inner conductors and one or more insulator parts to provide a coaxial, biaxial, or triaxial connector; in this embodiment, the vehicle-mounted Ethernet connector is a biaxial connector, and thus, when viewed longitudinally, the cross-section of the outer conductor 100 is in the shape of a kidney-shaped hole.

[0021] Please refer to Figures 1 to 2 As shown, the outer conductor 100 includes a main body portion 10 extending longitudinally, a head portion 20 located at the longitudinal front end of the main body portion 10, and a convex portion 30 connecting the main body portion 10 and the head portion 20. In this embodiment, the outer conductor 100 is a drawn part with a uniform wall thickness, thereby improving the dimensional stability of the vehicle-mounted Ethernet connector; moreover, the drawn part itself has no seam of the stamping ring, reducing radio frequency leakage, and thus improving the performance of the vehicle-mounted Ethernet connector.

[0022] The main body portion 10 is provided with two flat main board portions 11 arranged oppositely and two arc-shaped side board portions 12 connecting the two ends of the two main board portions 11. A receiving cavity 110 is formed by enclosing the two main board portions 11 and the two side board portions 12. The receiving cavity 110 penetrates the outer conductor 100 longitudinally to receive the inner conductor and the insulator and for the docking connector to be inserted.

[0023] The head portion 20 is for guiding the insertion of the docking connector and is provided with an annular portion 21 located at the longitudinal frontmost end, a guiding portion 22 protruding outward from the rear side of the annular portion 21, and a connecting portion 23 connecting the guiding portion 22 and the convex portion 30. The inner diameters of the annular portion 21, the guiding portion 22, and the connecting portion 23 increase in sequence. Combining Figure 3 and Figure 4 As shown, when viewed from a direction perpendicular to the longitudinal direction, the cross-sectional area of the head portion 20 is smaller than the cross-sectional area of the main body portion 10.

[0024] The outer surface of the annular portion 21 is a horizontal line parallel to the longitudinal direction, the outer surface of the guiding portion 22 is composed of two arcs with different centers, and the outer surface of the connecting portion 23 is a straight line forming a certain angle with the longitudinal direction. At the same time, the annular portion 21 is provided with a guiding surface 210 on the inner wall, and the inner diameter of the guiding surface 210 gradually decreases from front to back longitudinally to guide the insertion of the docking connector.

[0025] The protruding portion 30 protrudes outward for the docking outer conductor of the docking connector to be inserted, and is provided with a contact section 31 protruding outward, a horizontal section 32 connected between the contact section 31 and the connecting portion 23, and an arc section 33 connected between the contact section 31 and the main body portion 10. When observed from a direction perpendicular to the longitudinal direction, the outer surfaces of the contact section 31 and the arc section 33 are respectively arcs with two different center points, the outer surface of the horizontal section 32 is a horizontal line parallel to the longitudinal direction, and the outer diameter of the horizontal section 32 is greater than the outer diameter of the annular portion 21. When the outer conductor 100 is inserted into the docking connector, the contact section 31 contacts the docking outer conductor of the docking connector, thus ensuring that the outer conductor 100 also provides electromagnetic shielding on its outer side surface.

[0026] The outer conductor 100 is further provided with several slots 40 extending longitudinally backward from the front end face of the head 20. The slots 40 communicate with the receiving cavity 110 and sequentially extend through the head 20, the protruding portion 30, and at least part of the main body portion 10, so that the outer conductor 100 forms a split structure. This split structure provides the holding force during the connection of the in-vehicle Ethernet connector and has a greater cost advantage compared with die-castings. Usually, the number of the slots 40 is 4 to 8, so as to ensure reliable connection of the product. In this embodiment, the number of the slots 40 is 4 and they respectively extend to the corresponding main board portion 11 and side board portion 12.

[0027] In the present utility model, the outer conductor 100 is a drawn part and is provided with several slots 40 extending longitudinally backward from the front end face of the head 20. The slots 40 sequentially extend through the head 20, the protruding portion 30, and at least part of the main body portion 10, so that the outer conductor 100 forms a split structure. The outer conductor 100 is a drawn part with uniform wall thickness, which improves the dimensional stability of the product. And there is no seam of the stamping forming ring in the drawn part, reducing radio frequency leakage, thereby improving the product performance. At the same time, this split structure provides the holding force for the connection of the product and has a greater cost advantage compared with die-castings.
