[0043] Optionally, it also includes two second positioning parts, which are respectively disposed on the left and right sides of the first insulator and extend downward. One of the second positioning parts is provided with a fifth gap between it and the first insertion part, and the other second positioning part is provided with a sixth gap between it and the second insertion part.

[0044] Specifically, when the wire-end connector is inserted into the corresponding board-end connector, the two second positioning parts respectively fit against the outer side of the board-end connector's housing, playing a role in insertion and removal positioning and guidance. During insertion and removal, they further guide and position the connector in the length direction, improving insertion stability.
