[0020] Please see Figures 1 to 3 As shown, a preferred embodiment of the present invention discloses a vehicle connector 100, including a mounting body 10, a mating body 20 fixed on the mounting body 10, a terminal portion 30, and a shielding plate 40 and a metal cover plate 50 fixed on the mounting body 10; the vehicle connector 100 is used for mating connectors to be inserted to realize signal transmission.

[0021] In this embodiment, the mounting body 10 is integrally formed by die casting of metal material. Of course, the mounting body 10 can also be formed by other methods, such as powder metal injection molding. The mounting body 10 has a base 11 for holding the docking body 20 and several docking portions 12 integrally formed with the base 11. The docking portions 12 protrude forward into the docking cavity 21 of the docking body 20. The base 11 has a mounting groove 13 for holding the terminal portion 30. The docking portions 12 have guide holes that are parallel to the center line of the insertion direction and communicate with the mounting groove 13. The center line of each docking portion 12 is parallel to the center line of the other docking portion 12.

[0022] In this embodiment, by integrally molding the base 11 with several mating portions 12, i.e., molding the mounting body 10 in a single step in the mold, the molding stability of the several mating portions 12 can be ensured. This means that the positional or coaxiality of the several mating portions 12 remains consistent, that is, the center lines of each mating portion 12 are parallel to each other. Alternatively, it can be understood that the mounting groove 13 has a center line extending along the insertion direction of the terminal portion 30, and the center line of the mounting groove 13 coincides with the center line of the mating portion 12. This facilitates accurate insertion of the connector, prevents misalignment or damage to the contact portion 34 of the conductive terminal 32, and ensures reliable mating. Especially in the automotive field, where the automotive connector 100 is frequently used for insertion and removal, ensuring reliable contact of the contact portion 34 of the conductive terminal 32 also prevents poor contact and protects personal and property safety.

[0023] Specifically, the base 11 has four positioning posts 111 protruding downwards from the bottom surface, located at the four corners of the base 11, to accurately mount the mounting body 10 onto a circuit board. The mating portion 12 has several contact surfaces 121 and non-contact surfaces 122 on its outer periphery. The contact surfaces 121 are arc surfaces on the same circumference, and the non-contact surfaces 122 are planes located inside the circumference of the contact surfaces 121. Furthermore, the contact surfaces 121 and non-contact surfaces 122 are spaced apart from each other and evenly distributed on the outer periphery of the mating portion 12. The non-contact surfaces 122 reduce the insertion force when the vehicle connector 100 is plugged in, thereby ensuring that the vehicle connector 100 can be plugged in smoothly.

[0024] The docking body 20 is made of insulating material and has a docking cavity 21 that extends from front to back. The front end of the docking body 20 is for the docking connector to be inserted into the docking cavity 21 to form a docking and lock the docking connector. The rear end of the docking body 20 is fixed to the mounting body 10 to combine the mounting body 10 and the docking body 20 together. In this embodiment, the docking body 20 has two side walls 22 located on both sides of the docking cavity 21, and each of the two side walls 22 has a retaining part 23 located on the rear side. The mounting body 10 has a retaining part 14 protruding outward from the base 11, and the retaining part 23 is fastened to the retaining part 14.

[0025] The docking body 20 is provided with a locking part 24 located on the upper side of the docking cavity 21 to lock the docking connector and prevent the docking connector from accidentally disengaging, thus avoiding safety hazards during vehicle operation. The locking part 24 has a front wall 241, reinforcing walls extending rearward from both sides of the front wall 241, and a locking groove 242 located between the reinforcing walls. The locking groove 242 communicates with the docking cavity 21. The reinforcing walls can improve the strength of the locking part 24 and ensure the stable locking of the docking connector under tension. This is especially important when the vehicle is traveling at high speed or on uneven road surfaces.

[0026] The terminal portion 30 is fixed within the base 11 and protrudes forward into the mating portion 12. The terminal portion 30 includes an insulating body 31 and a conductive terminal 32 disposed within the insulating body 31. The conductive terminal 32 has a holding portion 33 fixed on the insulating body 31, a contact portion 34 protruding from one end of the holding portion 33 into the insulating body 31, and a connecting foot 35 extending from the other end of the holding portion 33 into the insulating body 31. The contact portion 34 of the conductive terminal 32 protrudes into the guide hole.

[0027] The insulating body 31 has a rear seat 36 and a support body 37 protruding forward from the rear seat 36. The rear seat 36 and the support body 37 are fixed in the mounting groove 13 of the mounting body 10, and the front end of the support body 37 protrudes into the guide hole. The contact portion 34 of the conductive terminal 32 protrudes from the front end of the support body 37 and protrudes into the guide hole. In this embodiment, the front end of the support body 37 is tapered to guide the positioning and docking of the connector.

[0028] In this embodiment, the retaining portion 33 of the conductive terminal 32 has a first connecting portion 331 connecting to the contact portion 34 and a second connecting portion 332 connecting the first connecting portion 331. The first connecting portion 331 and the second connecting portion 332 are perpendicular to each other, and the connecting leg 35 is connected to the end of the second connecting portion 332. The first connecting portion 331 and the second connecting portion 332 are arranged perpendicular to each other, which facilitates the insertion and positioning of the conductive terminal 32 within the mounting body 10.

[0029] In this embodiment, the terminal portion 30 includes a first terminal portion 301 and a second terminal portion 302. Both the first terminal portion 301 and the second terminal portion 302 include an insulating body 31 and a conductive terminal 32 disposed within the insulating body 31. The conductive terminal 32 has a holding portion 33 fixed to the insulating body 31, a contact portion 34 protruding from one end of the holding portion 33 into the insulating body 31, and a connecting foot 35 extending from the other end of the holding portion 33 into the insulating body 31. The shielding plate 40 is located between the connecting foot 35 of the first terminal portion 301 and the connecting foot 35 of the second terminal portion 302. Compared to the prior art, this improves the resistance to signal interference between the first terminal portion 301 and the second terminal portion 302, and increases the transmission efficiency between the vehicle connector 100 and the mating connector. Anti-interference is particularly important in the field of autonomous driving.

[0030] The shielding plate 40 is flat, and the base 11 has a recessed slot from the bottom. The shielding plate 40 is inserted into the slot of the mounting body 10. The shielding plate 40 has protrusions on both sides and a protrusion extending to one side. The force directions of the protrusions and protrusions on the mounting body 10 are perpendicular to each other. Through multi-directional positioning, the shielding plate 40 is stably fixed to the mounting body 10. The rear seat 36 extends downward perpendicularly to the support 37 and abuts against the mounting body 10 or the shielding plate 40 to determine the positioning of the terminal part 30 in the mounting body 10. Furthermore, the shielding plate 40 is formed by stamping, which facilitates the forming of the protrusions and protrusions and reduces manufacturing costs. At the same time, the cover plate 50 is fixed to the rear side of the base 11 of the mounting body 10 to cover the rear side of the rear seat 36 of the insulating body 31 and the rear side of the holding part 33 of the conductive terminal 32.

[0031] In this invention, the mating part 12 is provided with several contact surfaces 121 and non-contact surfaces 122 on its outer periphery. The contact surfaces 121 are arc surfaces on the same circumference, and the non-contact surfaces 122 are planes located inside the circumference of the contact surfaces 121. The provision of the non-contact surfaces 122 reduces the insertion force when the vehicle connector 100 is plugged in, thereby ensuring that the vehicle connector 100 can be plugged in smoothly and avoiding connector malfunction during the plugging operation.

[0032] In summary, the above are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of the present utility model should still fall within the scope of the present utility model patent.
