In the present embodiment, the two first terminals 1 in a pair are identical but have different angles with the horizontal direction, specifically, one of the two first terminals 1 in a pair is arranged in the horizontal direction, and the other of the two first terminals 1 in a pair is arranged in the vertical direction, that is, the two first terminals 1 are in a vertical state.

Specifically, referring to fig. 1, as a specific implementation manner of this embodiment, any one of the two paired first terminals 1 is disposed in parallel with the second terminal 2, so that the layout of the terminals can be simplified.

Specifically, referring to fig. 1, as a specific implementation manner of the present embodiment, the first terminal 1 and the second terminal 2 have the same shape, which facilitates the manufacturing of the terminals and reduces the processing cost.

Specifically, referring to fig. 1, as a specific implementation manner of this embodiment, the first terminal 1 and the second terminal 2 are both long-shaped, so as to be inserted into the pin hole 2001 of the PCB 200.

Specifically, referring to fig. 1, as a specific implementation manner of the present embodiment, a pair of the first terminal 1 and the second terminal 2 is provided, that is, a total of four terminals are provided, so that the plug-in terminal structure 100 has a function of preventing reverse insertion.

Since the two first terminals 1 in the pair are in a non-centrosymmetric state and/or the two second terminals 2 in the pair are in a non-centrosymmetric state, when the insert terminal structure 100 is rotated by 180 degrees in the insertion direction, at least one of the first terminals 1 in the pair and the second terminals 2 in the pair is not overlapped with the terminal before the rotation. Therefore, the plug terminal structure 100 cannot be inserted into the plug pin hole 2001 of the PCB 200 after being rotated by 180 degrees in the insertion direction, and the phenomenon of reverse insertion of the plug terminal structure 100 can be prevented.
