An electrical connector and assembly are provided. The electrical connector includes an insulative base and terminal columns. Each terminal column includes ground terminals and differential signal terminal pairs, the terminal columns are spaced apart from each other. Each ground terminal has a body portion and three elastic contact portions. Each signal terminal of each differential signal terminal pair has a body portion and an elastic contact portion. In two adjacent terminal columns, orthographic projections of the two elastic contact portions of each differential signal terminal pair are positioned within a range defined by a width of the elastic contact portions of the corresponding ground terminal, and an orthographic projection of the elastic contact portion positioned in a middle of each around terminal in the second direction is positioned within a range defined by a width of the two elastic contact portions of the corresponding differential signal terminal pair.
