An electrical connector includes multiple electrical modules sequentially stacked along a vertical direction. Each electrical module includes an insulating block being arc-shaped, a row of conductors fixed to the insulating block, and a first shielding member. The row of conductors includes multiple first grounding conductors and multiple pairs of first signal conductors arranged on the insulating block along a left-right direction. The two first signal conductors in a same pair of first signal conductors have a same length. The first shielding member has a first main body portion overlapping with a projection of one pair of first signal conductors in the vertical direction. The first shielding member and each conductor bend and extend downward from a top thereof and backward from a front thereof to be arc-shaped. The first contact portions of the row of conductors located on the same electrical module are located on a same horizontal plane.
