[0027] Please see Figures 1 to 7 As shown, a preferred embodiment of this utility model discloses an in-vehicle connector assembly for mechanically and electrically connecting a portable device to an automobile. The in-vehicle connector assembly includes a female connector 100 and a male connector 200 rotatably inserted into the female connector 100. The female connector 100 is embedded in the vehicle's cabin and electrically connected to the vehicle's electrical system; it can be integrally mounted inside the center console, thus not affecting the layout outside the center console. The male connector 200 is embedded in a bracket module to provide a holding function for the portable device.

[0028] Please see Figures 2 to 4 As shown, the female connector 100 includes a female connector body 10, a plurality of female connector terminals 20 fixed within the female connector body 10, and a female connector housing 30 that houses the female connector body 10. The female connector housing 30 is a metal housing. The female connector body 10 has an annular portion 11 and a plurality of extension portions 12 extending rearward from the rear end face of the annular portion 11. The female connector terminals 20 are assembled axially from front to back into the annular portion 11 of the female connector body 10.

[0029] The female connector body 10 has a mating cavity 110 recessed inward from its front end, which extends inward from the axial front end of the annular portion 11. The female connector terminal 20 has a holding portion 21 fixed within the annular portion 11 and an elastic arm 22 extending circumferentially from the front end of the holding portion 21. Several elastic arms 22 of the female connector terminals 20 are evenly arranged circumferentially on the inner circumferential wall of the mating cavity 110, and each elastic arm 22 has a contact portion 221 protruding radially inward into the mating cavity 110 for elastically abutting against the contact arm 61 of the male connector terminal 60.

[0030] Specifically, the female seat body 10 is provided with several vertical grooves 111 extending axially through the annular portion 11 and several circumferential grooves 112 located on the inner peripheral wall of the docking cavity 110. The vertical grooves 111 are connected to the corresponding circumferential grooves 112. The retaining portion 21 is accommodated in the vertical grooves 111, and the elastic arm 22 is retained in the circumferential grooves 112. Further, the vertical grooves 111 extend axially backward through the extension portion 12. Part of the retaining portion 21 is retained in the extension portion 12 and is provided with a welding portion 23 extending rearward from the rear end face of the extension portion 12. The welding portion 23 is used to connect to the female seat wires, and then electrically connect to the vehicle circuit system.

[0031] Simultaneously, the circumferential groove 112 of the annular portion 11 is recessed from the inner peripheral wall of the mating cavity 110, and the circumferential groove 112 extends axially forward through the front end face of the annular portion 11. The free end of the elastic arm 22 is engaged with the inner peripheral wall of the annular portion 11, so that the elastic arm 22 can be stably fixed to the annular portion 11. Furthermore, since the elastic arm 22 of the female terminal 20 is a long strip structure extending circumferentially, that is, the elastic arm 22 has a long lever arm, thus ensuring contact stability.

[0032] The female connector housing 30 has a front housing portion 31, a rear housing portion 32 extending rearward from the rear end of the front housing portion 31, and a connecting protrusion 33 extending rearward from the rear end of the rear housing portion 32. The connecting protrusion 33 has external threads so that the female connector 100 can be stably fixed in the center console of the vehicle. The front housing portion 31 has a receiving cavity 311 recessed inward from the front end, a protrusion 312 extending forward axially from the bottom wall of the receiving cavity 311, and several through holes (not shown) extending axially through the rear end face of the front housing portion 31. The through holes communicate with the receiving cavity 311 and are located on the outer periphery of the rear housing portion 32.

[0033] The annular portion 11 of the female connector body 10 is accommodated in the receiving cavity 311 and abuts against the inner peripheral wall of the receiving cavity 311, so that the female connector body 10 is located within the front portion 31 of the housing at its upper radial limit. Simultaneously, the front end face of the annular portion 11 of the female connector body 10 is flush with the front end face of the front portion 31 of the housing of the female connector housing 30. The extension portion 12 of the female connector body 10 passes through the through hole and extends beyond the rear end face of the front portion 31 of the housing; that is, the female connector body 10 isolates the fixing portion 21 of the female connector terminal 20 from the front portion 31 of the housing through the extension portion 12 to prevent short circuit between the two.

[0034] Simultaneously, the protrusion 312 extends axially forward into the mating cavity 110 of the female connector body 10, and the protrusion 312 does not contact the elastic arm 22 of the female connector terminal 20. Furthermore, the female connector housing 30 is provided with a mounting cavity 301 recessed inward from the axial front end. The mounting cavity 301 extends axially through the protrusion 312 and into the rear part 32 of the housing. That is, the mounting cavity 301 passes through the female connector body 10 and has internal threads for the threaded post 72 of the male connector 200 to be inserted.

[0035] Please see Figures 5 to 7 As shown, the male connector 200 includes a male connector body 50, a plurality of male connector terminals 60 fixed on the male connector body 50, and a male connector housing 70 supporting the male connector body 50. The male connector housing 70 is a metal housing. The male connector housing 70 has a base 71 and a threaded post portion 72 extending axially forward from the base 71. The threaded post portion 72 has external threads, and the threaded post portion 72 is threadedly connected to the mounting cavity 301, so that the male connector 200 is screwed onto the female connector 100.

[0036] The male connector body 50 has an annular body 51 sleeved on the outer periphery of the threaded post portion 72 and several protrusions 52 extending rearward from the annular body 51. The base 71 of the male connector housing 70 has a through groove 711 extending axially through the base 71. The annular body 51 of the male connector body 50 abuts against the front end face of the base 71, and the protrusions 52 pass through the through groove 711 and extend out of the rear end face of the base 71. In this embodiment, the male connector body 50 is injection molded onto the male connector terminal 60 and the male connector housing 70, and a retaining groove 501 is formed between the annular body 51 of the male connector body 50 and the threaded post portion 72 of the male connector housing 70. When the male connector connector 200 is screwed to the female connector connector 100, the front end of the protrusion 312 of the female connector housing 30 is inserted into the retaining groove 501.

[0037] The male connector 60 has a sheet-like contact arm 61 exposed on the outer peripheral wall of the male connector body 50, and an extension arm 62 extending axially rearward from the contact arm 61. The contact arm 61 is used for elastic contact with the elastic arm 22 of the female connector 20. Since the contact arm 61 of the male connector 60 has a sheet-like structure, the contact portion 221 of the elastic arm 22 has a long contact area on the contact arm 61. Furthermore, since the contact arms 61 are evenly distributed circumferentially on the outer peripheral wall of the male connector body 50, adding more male connectors 60 as needed will not increase the axial length of the male connector 200.

[0038] Specifically, several contact arms 61 are evenly attached to the outer peripheral wall of the annular body 51 in a circumferential direction, and the extension arm 62 is fixed within the annular body 51 and the protrusion 52 and is provided with a connecting foot 621 extending rearward from the rear end face of the protrusion 52. The connecting foot 621 is used to connect to the male connector wire. At the same time, since the protrusion 52 of the male connector body 50 passes through the through groove 711 and extends out of the rear end face of the base 71, the male connector body 50 isolates the extension arm 62 of the male connector terminal 60 from the base 71 through the protrusion 52 to prevent short circuit between the two.

[0039] When the male connector 200 is inserted into the female connector 100, the male connector body 50 is housed within the mating cavity 110 of the female connector body 10, and the front end of the protrusion 312 of the female connector housing 30 is inserted into the retaining groove 501. Furthermore, when the male connector 200 is screwed into the female connector 100, the contact portion 221 of the female connector terminal 20 elastically abuts against the contact arm 61 of the male connector terminal 60. This vehicle connector assembly allows the portable device to be stably fixed inside the vehicle and enables the vehicle to charge the portable device, meaning the portable device does not require an external wiring connection to the charging interface in the central control area. Simultaneously, both the female connector terminal 20 and the male connector terminal 60 are evenly arranged circumferentially, meaning the number of corresponding terminals in the vehicle connector assembly can be increased as needed, thereby achieving functional diversification of the vehicle connector assembly. Furthermore, since the elastic arm 22 of the female connector 20 and the contact arm 61 of the male connector 60 are both located on the corresponding peripheral walls, adding the number of corresponding terminals in this case will not increase the axial length of the female connector 100 and the male connector 200, that is, adding the number of terminals will not change the overall volume of the vehicle connector assembly.

[0040] In this invention, the female connector 20 is provided with a holding portion 21 fixed within the annular portion 11 and an elastic arm 22 extending circumferentially from the front end of the holding portion 21. Several elastic arms 22 of the female connector 20 are evenly arranged circumferentially on the inner circumferential wall of the mating cavity 110, and each elastic arm 22 is provided with a contact portion 221 protruding into the mating cavity 110. The female connector 100 can simultaneously achieve mechanical and electrical connections to portable devices. Furthermore, the elastic arm 22 of the female connector 20 is a long strip-shaped structure extending circumferentially, meaning that the elastic arm 22 has a relatively long lever arm, thereby ensuring contact stability.

[0041] 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.
