High-frequency board-to-board connector

The utility model relates to a high-frequency board-to-board connector, which comprises a male seat and a female seat which are mutually plugged, the male seat and the female seat are respectively provided with two terminals, the two terminals of the male seat are respectively abutted against the two terminals of the female seat in a one-to-one correspondence manner, and the contact arms of the two terminals of the male seat are overturned by 90 +/-10 degrees relative to the contact arms, so that the contact parts are positioned on a non-stamping cut surface. The contact parts of the two terminals of the female seat are both located on the adjacent surfaces of the two stamping cut surfaces of the terminals, namely located on the non-stamping cut surfaces. As the male seat terminal and the female seat terminal are in non-cut surface contact, the non-cut surface is smoother than a stamping cut surface, and signals are not easy to break, so that the connector can pass a high-frequency test; the bending width of
