[0001] The utility model relates to the technical field of in-vehicle Ethernet connectors, and particularly relates to an outer conductor structure for an in-vehicle Ethernet connector. Background Art
[0002] At present, the outer conductors of in-vehicle Ethernet connectors on the market are stamped parts or die-cast parts. The advantage of stamped parts is that they are convenient to operate, have high production efficiency, and are easy to realize mechanization and automation. However, the disadvantage is that there are gaps at the closing seams of stamping forming, with large dimensional variations and radio frequency leakage defects. At the same time, die-cast parts themselves have the problem of high cost.
[0003] Therefore, it is hoped to propose a new outer conductor structure to overcome the above defects. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an outer conductor structure for an in-vehicle Ethernet connector, which is a drawn part with uniform wall thickness, improving the dimensional stability of the product.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: An outer conductor structure is used in an in-vehicle Ethernet connector. The outer conductor structure includes a main body portion extending longitudinally and a head portion connected to the longitudinal front end of the main body portion. The main body portion is provided with two flat main board portions arranged oppositely and two arc-shaped side board portions connected to both ends of the two main board portions. The head portion is used to guide the insertion of a mating connector. The outer conductor structure is a drawn part and is provided with several elastic pieces located on the main board portion. The elastic pieces are torn from the main board portion and extend rearward longitudinally.
[0006] In a preferred embodiment, the elastic piece is entirely located outside the main body portion and is provided with a contact arm protruding outward from the main board portion, a folded-back portion bent inward from the contact arm, and a cantilever extending outward from the folded-back portion.
[0007] In a preferred embodiment, the contact arm is provided with a contact portion at the outermost end, and the distance from the free end of the cantilever to the main board portion is less than the distance from the contact portion to the main board portion.
[0008] In a preferred embodiment, the outer conductor structure includes a receiving cavity formed by enclosing the two main board portions and the two side board portions. The receiving cavity penetrates the outer conductor structure longitudinally for the insertion of the mating connector.
[0009] In a preferred embodiment, the main board portion is provided with a through groove corresponding to the elastic piece, and the through groove communicates with the receiving cavity; when the outer conductor structure is inserted into the mating connector, at least a part of the folded-back portion is received in the through groove.
[0010] In a preferred embodiment, several of the elastic pieces are symmetrically arranged on the two main board parts, and at least two of the elastic pieces are provided on each main board part.
[0011] In a preferred embodiment, the head is provided with an annular part at the foremost end in the longitudinal direction, a guiding part protruding outward from the rear side of the annular part, and a connecting part connecting the guiding part and the main body part. The inner diameters of the annular part, the guiding part, and the connecting part increase in sequence.
[0012] In a preferred embodiment, when observed from a direction perpendicular to the longitudinal direction, the outer surface of the annular part is a horizontal line parallel to the longitudinal direction, the outer surface of the guiding part is composed of two arcs with different center points, and the outer surface of the connecting part is a straight line forming a certain angle with the longitudinal direction.
[0013] In a preferred embodiment, the annular part is provided with a guiding surface on the inner wall, and the inner diameter of the guiding surface gradually decreases from front to back in the longitudinal direction.
[0014] In a preferred embodiment, when observed in the longitudinal direction, the cross-section of the outer conductor structure is in the shape of a kidney-shaped hole.
[0015] Compared with the prior art, the present utility model has the following beneficial effects: The outer conductor structure is a drawing part and is provided with several elastic pieces on the main board part. The elastic pieces are torn from the main board part and extend backward in the longitudinal direction to be formed. The outer conductor structure is a drawing part with uniform wall thickness, which improves the dimensional stability of the product; and there is no seam line of the stamping forming ring on the drawing part, reducing radio frequency leakage, thereby improving the product performance. At the same time, the structure of the elastic piece facilitates the insertion of the guiding connector. Due to the elastic force of the elastic piece itself, it provides a pulling force and provides reliable connection performance, and has a greater cost advantage compared with die-castings.

[0020] Please refer to Figures 1 to 4As shown, a preferred embodiment of the present utility model discloses an outer conductor structure 100 for use in a vehicle-mounted Ethernet connector (not shown). The outer conductor structure 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, so that when viewed longitudinally, the cross-section of the outer conductor structure 100 is in the shape of a kidney-shaped hole.
[0021] Please refer to Figures 1 to 2 As shown, the outer conductor structure 100 includes a main body portion 10 extending longitudinally, a head portion 20 connected to the longitudinal front end of the main body portion 10, and several elastic pieces 30 located on the main body portion 10. In this embodiment, the outer conductor structure 100 is a drawn part with uniform wall thickness, thereby improving the dimensional stability of the vehicle-mounted Ethernet connector; moreover, the drawn part does not have the seam line of the stamping forming 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 connected to both ends of the two main board portions 11. A receiving cavity 110 formed by enclosing the two main board portions 11 and the two side board portions 12 penetrates the outer conductor structure 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 front 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 main body portion 10. The inner diameters of the annular portion 21, the guiding portion 22, and the connecting portion 23 increase in sequence.
[0024] Combined with Figure 3 and Figure 4 As shown, when viewed from a direction perpendicular to the longitudinal direction, 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 center points, and the outer surface of the connecting portion 23 is a straight line at a certain angle to 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] In this embodiment, several of the elastic pieces 30 are located on the main board portion 11. Specifically, several of the elastic pieces 30 are symmetrically arranged on two main board portions 11, and each main board portion 11 has at least two elastic pieces 30. Usually, the number of the elastic pieces 30 is 4 to 6 to ensure reliable connection of the product. In this embodiment, the number of the elastic pieces 30 is 4. The elastic pieces 30 are torn from the main board portion 11 and formed by extending backward longitudinally. Further, the elastic pieces 30 are entirely located outside the main body portion 10 and are provided with a contact arm 31 protruding outward from the main board portion 11, a folding portion 32 bent inward from the contact arm 31, and a cantilever 33 extending outward from the folding portion 32.
[0026] The contact arm 31 is provided with a contact portion 310 at the outermost end. When the outer conductor structure 100 is inserted into the docking connector, the contact portion 310 contacts the docking outer conductor of the docking connector, thereby ensuring that the outer conductor structure 100 also provides electromagnetic shielding on its outer side surface. The distance from the free end of the cantilever 33 to the main board portion 11 is less than the distance from the contact portion 310 to the main board portion 11. The main board portion 11 is provided with a through groove 111 corresponding to the elastic piece 30, and the through groove 111 communicates with the receiving cavity 110. When the outer conductor structure 100 is inserted into the docking connector, at least a part of the folding portion 32 is received in the through groove 111. The structure of the elastic piece 30 facilitates the insertion of the guiding connector. Due to the elastic force of the elastic piece 30 itself, it provides a pulling force and reliable connection performance, and has a greater cost advantage compared with die-castings.
[0027] In the present utility model, the outer conductor structure 100 is a drawn part and is provided with several elastic pieces 30 on the main board portion 11. The elastic pieces 30 are torn from the main board portion 11 and formed by extending backward longitudinally. The outer conductor structure 100 is a drawn part with uniform wall thickness, which improves the dimensional stability of the product. And the drawn part has no seam of the stamping forming ring, reducing radio frequency leakage, thereby improving the product performance. At the same time, the structure of the elastic piece 30 facilitates the insertion of the guiding connector. Due to the elastic force of the elastic piece 30 itself, it provides a pulling force and reliable connection performance, and has a greater cost advantage compared with die-castings.
[0028] In summary, the above are only the preferred embodiments of the present utility model, and should not be used to limit the scope of the present utility model. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present utility model should still fall within the scope covered by the patent of the present utility model.
