Middle clamping piece and high-speed connector

A high-speed connector, comprising an insulating main body, a first terminal set, a second terminal set, a middle clamping piece, and a metal housing, wherein the insulating main body is mounted inside the metal housing, and the first terminal set, the second terminal set, and the middle clamping piece are connected to the insulating main body;

• the middle clamping piece is located between the first terminal set and the second terminal set, the first terminal set and the second terminal set are respectively provided with a high-speed signal terminal and a ground terminal, and each two high-speed signal terminals form one pair;
• the ground terminal in the first terminal set is located between two adjacent pairs of high-speed signal terminals;
• the ground terminal in the second terminal set is located at two sides of each pair of high-speed signal terminals, a middle clamping piece body of the middle clamping piece is provided with a ground contact part in contact with the ground terminal in the first terminal set and/or the ground terminal in the second terminal set, one edge or two edges of the middle clamping piece body is provided with a housing contact part extending out of a side face of the insulating main body and in contact with the metal housing, and the middle clamping piece body is provided with a middle clamping piece ground wall arranged on an outer side of a first pair of high-speed signal terminals of the first terminal set;
• and the middle clamping piece ground wall protrudes from a surface of the middle clamping piece body towards the first terminal set and is capable of serving as a reference ground for the first pair of high-speed signal terminals of the first terminal set.
