The first terminal body 2 is arranged inside the insulator 1, and the second terminal body 3 is arranged on the outer circumferential wall of the insulator 1.

[0033] The existing terminal assembly consists of an insulator and a cylindrical terminal inserted through the insulator. The cylindrical terminal is prepared by a turning process. Due to the limitations of the turning process and the size of the insulator, the number of cylindrical terminals set on the insulator is limited. To increase the number of cylindrical terminals, the size of the insulator must be increased accordingly, resulting in limited use.

[0034] Based on the above structure, the utility model arranges the first terminal body 2 in the insulator 1, and the second terminal body 3 on the outer circumferential wall of the insulator 1. By using the larger outer circumferential wall on the insulator 1 as the installation position of the second terminal body 3, the number of terminal bodies arranged on the insulator 1 under the same volume is increased, thereby realizing a miniaturized design of the terminal assembly.

[0035] Moreover, when the terminal assembly is produced, the utility model can first insert the first terminal body 2 into the insulator 1, perform wiring operations on the first terminal body 2, and then set the second terminal body 3 on the outer circumferential wall of the insulator 1 and perform wiring operations.

In this way, when the male end and the female end are docked, the second terminal bodies 3 at different ends can be in stable contact, ensuring stable connection and transmission of power, signals and data.

[0043] In some embodiments of the present application, the outer circumferential wall of the insulator 1 is provided with limiting grooves 11, the number of which is equal to the number of the second terminal bodies 3, and the second terminal bodies 3 are located in the limiting grooves 11; the second terminal body 3 is positioned by setting the limiting grooves 11 to ensure that its position is stable during use.
