[0025] When the first connector 1 is connected to the second connector 2, the first insulating body 11 and the second insulating body 21 are respectively paired and hinged together by the first support arm 111, the second support arm 112, the third support arm 211 and the fourth support arm 212, so that the first insulating body 11 and the second insulating body 21 can rotate relative to each other and adjust; and the first contact portion 121 of the first terminal 12 and the second contact portion 221 of the second terminal 22 are inserted and combined and can maintain a contacting posture while following the rotation adjustment of the first insulating body 11 and the second insulating body 21. The first arm 111, the second arm 112, the third arm 211, and the fourth arm 212 are respectively paired and hinged together, so that the first connector and the second connector are stably connected together and not easily separated, ensuring the conductive connection between the first terminal 12 and the second terminal 22; and the first connector and the second connector can rotate relative to each other for adjustment, thereby adjusting the installation angle according to the space: the vertical rotation range is 0° to 90°, which can be flexibly applied to more complex installation spaces, shortening the assembly time and improving the practicality and usability of the connector.

[0026] Figure 1 , 2As shown in Figures 3, 4, and 5, in this embodiment, the first support arm 111 and the fourth support arm 212 are hinged together, and the first support arm 111 is attached to the outside of the fourth support arm 212. A first hinge hole 1111 is provided on the first support arm 111, and a first hinge pin 2121 protruding outward is provided on the fourth support arm 212.

The second arm 112 is hinged to the third arm 211, with the third arm 211 resting against the outer side of the second arm 112. A second hinge hole 2111 is provided on the third arm 211, while the second arm 112 has an outwardly protruding second hinge pin 1121. The hinged connection between the second arm 112 and the third arm 211 is established by inserting the second hinge pin 1121 into the second hinge hole 2111. The first arm 111, second arm 112, third arm 211, and fourth arm 212 are respectively paired and hinged, forming an alternating arrangement, effectively increasing the structural integrity of the connection between the first and second connecting members, making the rotational connection more stable and reliable.

[0027] In this embodiment, there are multiple first terminals 12 arranged in a row, and the first contact portions 121 of the multiple first terminals 12 are respectively designed as blade-shaped and claw-shaped. There are also multiple second terminals 22, and the number and distribution of the second terminals 22 match the first terminals 12. The second contact portions 221 of the multiple second terminals 22 are also respectively designed as blade-shaped and claw-shaped.

This composite and interlaced design of blade-shaped and claw-shaped components helps to improve the insertion and connection performance of the first terminals 12 and the second terminals 22, ensures electrical conductivity, and meets the requirements for rotational adjustment.

[0028] In this embodiment, the outer surface of the root of the first support arm 111 is flush with the corresponding outer side of the first insulating body 11, while the outer surface of the root of the second support arm 112 is offset inward relative to the corresponding outer side of the first insulating body 11, forming a stepped first limiting part 113 on the first insulating body 11; the outer surface of the root of the third support arm 211 is flush with the corresponding outer side of the second insulating body 21, while the outer surface of the root of the fourth support arm 212 is offset inward relative to the corresponding outer side of the second insulating body 21, forming a stepped second limiting part 213 on the second insulating body 21; the first limiting part 113 and the second limiting part 213 are distributed on the left and right sides of the insertion direction, together limiting the relative rotation range between the first insulating body 11 and the second insulating body 21, so that the relative rotation angle between the first connector and the second connector can be adjusted from 0° to 90° up and down, which can be flexibly applied to more complex installation spaces.

[0029] Furthermore, in this embodiment, the first connector 1 and the second connector 2 are designed as identical integral components with the same structural form. This allows for arbitrary combination and use, minimizing inventory and reducing production costs. The first connector 1 and the second connector 2 in this embodiment are based on two terminal specifications, but are not limited to 2-pin specifications; they are applicable to even-numbered pin specifications.
