Referring to fig. 1 and 2, the present invention discloses a connector assembly 100, which includes a plate-end connector 10 and a wire-end connector 50 that are butted against each other. For convenience of description, it is defined in this specification that when the board-side connector 10 and the line-side connector 50 are butted, the butted end is a front end, and the end for connecting a cable is a rear end.
Referring to fig. 1, 3 and 4, the plate terminal connector 10 includes an annular insulating wall 11, a first annular terminal 20 embedded in an inner side wall surface of the annular insulating wall 11, and a first central terminal 30 accommodated in the annular insulating wall 11. The wire end connector 50 includes a second annular insulating wall 51 fittingly received in the annular insulating wall 11, a second annular terminal 60 disposed on an outer surface of the second annular insulating wall 51, the second annular terminal 60 being in contact with the first annular terminal 20, and a second central terminal 70 disposed in the second annular insulating wall 51, the second central terminal 70 being wrapped around the first central terminal 30.
Referring to fig. 5 and 6, in order to ensure that when the first central terminal 30 is abutted against the second central terminal 70, no deflection occurs between the first central terminal 30 and the annular insulating wall 11, and no deflection occurs between the second central terminal 70 and the second annular insulating wall 51. In this embodiment, the first central terminal 30 includes a first position-limiting portion 30a vertically extending along two sides of the first central terminal 30, so that the first position-limiting portion 30a has a U-shaped structure. The second central terminal 70 includes a second position-limiting portion 70a vertically extending along two sides of the second central terminal 70, so that the second position-limiting portion 70a is U-shaped. A square first limiting groove 12 is arranged on the inner side of the annular insulating wall 11, and the first limiting groove 12 is arranged at the rear end of the annular insulating wall 11. A square second limiting groove 52 is formed in the inner side of the second annular insulating wall 51, and the second limiting groove 52 is formed in the rear end of the second annular insulating wall 51. The first position-limiting portion 30a is fastened in the first position-limiting groove 12, and the second position-limiting portion 70a is fastened in the second position-limiting groove 52, so that the first central terminal 30 and the second central terminal 70 are prevented from deflecting.
Referring to fig. 3 and 8, the first ring terminal 20 includes a first terminal body 20a having a ring shape, and the second ring terminal 60 also includes a second terminal body 60a having a ring shape. In order to ensure that the first terminal body 20a and the second terminal body 20a maintain good contact communication, the first terminal body 20a does not completely cover the second terminal body 60a, and in order to facilitate recognition of whether the first terminal body 20a and the second terminal body 60a are in an optimal contact communication state, the insertion and extraction force when the first ring terminal 20 and the second ring terminal 60 are connected is enhanced. In this preferred embodiment, at least one recessed portion 20b is provided on the inner annular surface of the first terminal body 20a, and the recessed portion 20b is radially outwardly extruded from the inner annular surface of the first terminal body 20 a. At least one protrusion 60b is formed on the outer circumferential surface of the second terminal body 60a, and the protrusion 60b is radially outwardly extruded from the outer ring of the second terminal body 60 a. Therefore, when the recessed portion 20a and the projecting portion 60b are relatively overlapped, the first ring terminal 20 and the second ring terminal 60 are in an optimum contact communication state. At this time, the insertion and extraction force is more stable when the first ring terminal 20 and the second ring terminal 60 are mated.
Referring to fig. 1 to 3 again, in order to ensure that the plate-end connector 10 is aligned with the wire-end connector 50 in an optimal direction, the groove portion 20b overlaps the protrusion portion 60 b. In this preferred embodiment, the plate-end connector 10 is provided with a locking portion 13, and the locking portion 13 is disposed at the front end of the first ring terminal 20. And the locking part 13 comprises at least two guide bosses 13a annularly arranged on the inner side of the annular insulating wall 11, and the guide bosses 13a are inclined to the inner wall of the annular insulating wall 11 at an angle of 45 degrees. And the guide boss 13a is axially symmetrical to the annular insulating wall 11.
The wire end connector 50 includes a holding portion 53 disposed on the outer surface of the second annular insulating wall 51, and the holding portion 53 is disposed at the rear end of the second annular terminal 60. The holding portion 53 includes at least two guide grooves 53a annularly disposed on an outer surface of the second annular insulating wall 51, and the guide grooves 53a are recessed toward an inside of the second annular insulating wall 51. The guide groove 53a is inclined at an angle of 45 degrees to the rear end of the second annular insulating wall 51, and the guide groove 53a is axially symmetrical to the second annular insulating wall 51.

Thereby ensuring that the plate end connector 10 is optimally oriented to mate with the wire end connector 50.
Referring to fig. 3 and 4, in order to prevent moisture from penetrating through the opening of the second annular insulating wall 51 and affecting the first central terminal 30 and the second central terminal 70 which are butted to each other. In the preferred embodiment, the terminal connector 50 includes a circular plug 80 that closes the opening. Specifically, the opening of the second annular insulating wall 51 is not only sealed by the circular hole plug 80, but also isolated from moisture entering the inner wall of the second annular insulating wall 51 by a waterproof adhesive between the opening of the second annular insulating wall 51 and the circular hole plug 80, so as to affect the butt joint of the first central terminal 30 and the second central terminal 70.
Referring again to fig. 3, the connector assembly 100 is mounted on a housing 90, in which the housing 90 covers the board-side connector 10 and the cable-side connector 50, and the rear end of the connector assembly 100 for connecting with a cable is exposed from the housing 90.
Referring to fig. 1 to 3, in order to prevent moisture from penetrating from the rear end of the connector assembly 100, the connector assembly 100 is prevented from being damaged. In this preferred embodiment, the second annular insulating wall 51 includes an extension portion 54, the extension portion 54 is disposed at the rear end of the second annular insulating wall 51 and annularly protrudes from the second annular insulating wall 51, and a gasket 55 is disposed on a front end surface of the extension portion 54. Specifically, the gasket 55 has a waterproof function and is disposed between the housing 90 and the extension portion 54 to isolate moisture from entering the housing 90, so as to affect the normal operation of the board end connector 10 and the cable end connector 50.
Referring to fig. 3 and 4, the wire end connector 50 includes at least one annular groove 56 disposed on an outer surface of the second annular insulating wall 51, the annular groove 56 is disposed at a front end of the holding portion 53, and a sealing ring 81 is circumferentially received in the annular groove 56, and the sealing ring 81 protrudes from the outer surface of the second annular insulating wall 51.
