[0030] Please see Figures 1 to 10As 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.

[0031] Please see Figures 2 to 6 As shown, the female connector 100 includes a female connector body 10, a plurality of female connector terminals 20 fixed on 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 body 11 and a protrusion 12 extending rearward from the rear end of the annular body 11. Furthermore, the female connector body 10 has an annular mating cavity 110 recessed inward from its top surface. In this embodiment, the mating cavity 110 is formed by recessing inward from the top surface of the annular body 11.

[0032] The female terminal 20 includes a first annular terminal 21 exposed on the outer annular wall of the docking cavity 110, a second annular terminal 22 exposed on the inner annular wall of the docking cavity 110, and a third annular terminal 23 exposed on the bottom wall of the docking cavity 110. Specifically, the first annular terminal 21 is provided with a first annular contact arm 211 attached to the outer annular wall of the docking cavity 110 and a first extension arm 212 extending axially rearward from the first annular contact arm 211; the second annular terminal 22 is provided with a second annular contact arm 221 attached to the inner annular wall of the docking cavity 110 and a second extension arm 222 extending axially rearward from the second annular contact arm 221; and the third annular terminal 23 is provided with a third annular contact arm 231 attached to the bottom wall of the docking cavity 110 and a third extension arm 232 extending axially rearward from the third annular contact arm 231.

[0033] The first annular contact arm 211, the second annular contact arm 221, and the third annular contact arm 231 of the female connector terminal 20 are all annular structures to allow elastic contact with the male connector terminal 70 of the male connector 200. This allows the female connector terminal 20 to make full-area contact on three sides of the female connector body 10, which can significantly reduce ground current surge damage caused by poor contact between the female connector terminal 20 and the male connector terminal 70, thereby improving the life of the vehicle connector assembly. At the same time, the first extension arm 212, the second extension arm 222, and the third extension arm 232 of the female connector terminal 20 are all fixed in the same protrusion 12 and have connecting feet that extend rearward from the axial rear end face of the protrusion 12. The connecting feet are used to connect to the corresponding female connector wire 50, and then electrically connect to the vehicle circuit system.

[0034] 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 a through hole (not shown) extending axially through the rear end face of the front housing portion 31.

[0035] The annular body 11 of the female connector body 10 is accommodated within the receiving cavity 311 and sleeved on the outer periphery of the protrusion 312, so that the female connector body 10 is located within the front portion 31 of the housing at its radial upper limit. The protrusion 12 of the female connector body 10 passes through the through hole and extends out of the rear end face of the front portion 31 of the housing, that is, the female connector body 10 isolates the extension arm of the female connector terminal 20 from the front portion 31 of the housing through the protrusion 12 to prevent short circuit between the two. At the same time, the female connector housing 30 is also provided with a mounting cavity 301 recessed inward from the front end face of the front portion 31 of the housing. The mounting cavity 301 passes through the protrusion 312 axially and extends into the rear portion 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 portion 82 of the male connector 200 to be rotatably inserted.

[0036] The female connector 100 also includes an insulating block 40 integrally injection molded on the rear part 32 of the housing. The insulating block 40 is used to seal the connecting feet of the female connector terminal 20 and the female connector wire 50 at the rear part 32 of the housing, thereby preventing external moisture from contacting the female connector terminal 20 or the female connector wire 50 and causing a short circuit. At the same time, the female connector body 10 is also provided with a retaining part 13 extending rearward from the rear end face of the annular body 11. In this embodiment, the retaining part 13 is located on the opposite side of the protrusion 12. The retaining part 13 passes through the through hole of the front part 31 of the housing and is fastened to the rear end face of the front part 31 of the housing, so that the female connector body 10 is axially fixed to the female connector housing 30.

[0037] Please see Figures 7 to 10 As shown, the male connector 200 includes a male connector body 60, a plurality of male connector terminals 70 fixed on the male connector body 60, and a male connector housing 80 supporting the male connector body 60. The male connector housing 80 is a metal housing. The male connector housing 80 has a base 81 and a threaded post portion 82 extending axially forward from the base 81. The threaded post portion 82 has external threads, and the threaded post portion 82 is threadedly connected to the mounting cavity 301, allowing the male connector 200 to be screwed onto the female connector 100.

[0038] The male seat body 60 has a first body 61 sleeved on the outer periphery of the threaded post portion 82 and a second body 62 connected to the front end of the first body 61. The second body 62 covers the axial front portion of the first body 61. The first body 61 has an annular portion 611 sleeved on the outer periphery of the threaded post portion 82 and several extension portions 612 extending rearward from the rear end face of the annular portion 611. The base 81 has a through groove 811 extending through the base 81 axially. The annular portion 611 abuts against the front end face of the base 81, and the extension portions 82 pass through the through groove 811 and extend out of the rear end face of the base 81.

[0039] The second body 62 shields the outer peripheral wall, inner peripheral wall, and front end face of the front portion of the annular portion 611 of the first body 61. Specifically, the second body 62 is provided with an annular shielding portion 621 sleeved on the outer periphery of the front portion of the annular portion 611 and a latching portion 622 extending axially rearward from the shielding portion 621. An accommodating space is formed between the shielding portion 621 of the second body 62 and the front portion of the annular portion 611, and the male connector terminal 70 is partially accommodated in the accommodating space. In this embodiment, the latching portion 622 is located inside the annular portion 611, and the latching portion 622 passes through the through groove 811 and is fastened in the rear end face of the base 81, so that the male connector body 60 is axially fixed to the male connector housing 80.

[0040] The male connector terminal 70 is assembled onto the male connector body 60, and the male connector terminal 70 includes a first elastic terminal 71 protruding from the outer peripheral wall of the annular portion 611, a second elastic terminal 72 protruding from the inner peripheral wall of the annular portion 611, and a third elastic terminal 73 protruding from the front end face of the annular portion 71, so as to elastically abut against the female connector terminal 20 of the female connector 100. Specifically, the first elastic terminal 71 is provided with a first holding portion 711 fixed to the outer peripheral wall of the annular portion 611 and a plurality of first elastic arms 712 torn from the first holding portion 711 and extending circumferentially; the second elastic terminal 72 is provided with a second holding portion 721 fixed to the inner peripheral wall of the annular portion 611 and a second elastic arm 722 torn from the second holding portion 721 and extending circumferentially; the third elastic terminal 73 is provided with a third elastic arm 732 exposed to the front end face of the annular portion 611 and extending circumferentially. In this embodiment, the first elastic arm 712 and the second elastic arm 722 extend in opposite directions in the circumferential direction.

[0041] In this embodiment, the first elastic arm 712 protrudes from the front outer peripheral wall of the annular portion 611, the second elastic arm 722 protrudes from the front inner peripheral wall of the annular portion 611, and the third elastic arm 732 protrudes from the front end face of the annular portion 611, for elastically abutting against the female terminal 20 of the female connector 100. Simultaneously, the first elastic terminal 71 has a first leg 713 extending axially rearward from the first holding portion 711, the second elastic terminal 72 has a second leg 723 extending axially rearward from the second holding portion 721, and the third elastic terminal 73 has a third leg 733 extending axially rearward from the third elastic arm 732. The first leg 713, the second leg 723, and the third leg 733 are respectively held within the annular portion 611 and the corresponding extension portion 612, and each has a welding portion extending rearward from the rear end face of the extension portion 612. The welding portion is used to connect to the corresponding male connector wire 90. Furthermore, since the extension 612 of the male connector body 60 passes through the through groove 811 and extends out of the rear end face of the base 81, the male connector body 60 isolates the foot of the male connector terminal 70 from the base 81 through the extension 612 to prevent short circuit between the two.

[0042] A receiving space is formed between the shielding portion 621 of the second body 62 and the front portion of the annular portion 611 of the first body 61. The first elastic arm 712, the second elastic arm 722, and the third elastic arm 732 are all housed within the receiving space and can move within it. Meanwhile, the shielding portion 621 has several openings on its outer peripheral wall, inner peripheral wall, and front end face. The first elastic arm 712, the second elastic arm 722, and the third elastic arm 732 each have contact points that pass through the corresponding openings and protrude outwards from the outside of the shielding portion 621. These contact points are used to abut against the annular contact arm of the female terminal 20 of the female connector 100.

[0043] When the male connector 200 is inserted into the female connector 100, the threaded post 82 of the male connector housing 80 is inserted into the mounting cavity 301 of the female connector housing 30, and the male connector body 60 is inserted into the mating cavity 110 of the female connector body 10. When the male connector 200 is screwed into the female connector 100, the threaded post 82 of the male connector housing 80 is screwed to the bottom of the mounting cavity 301 of the female connector housing 30. At this time, the first elastic arm 712 of the first elastic terminal 71 abuts against the first annular contact arm 211 of the first annular terminal 21, the second elastic arm 722 of the second elastic terminal 72 abuts against the second annular contact arm 221 of the second annular terminal 22, and the third elastic arm 732 of the third elastic terminal 73 abuts against the third annular contact arm 231 of the third annular terminal 23.

[0044] In this invention, when the male connector 200 is screwed onto the female connector 100, the first elastic terminal 71 abuts against the first annular terminal 21, the second elastic terminal 72 abuts against the second annular terminal 22, and the third elastic terminal 73 abuts against the third annular terminal 23. 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, the three annular contact arms of the female terminal 20 can achieve full-area contact on three sides, significantly reducing ground current surge damage caused by poor contact between the female terminal 20 and the male terminal 70, thereby improving product lifespan.

[0045] 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.
