High-frequency electrical connector

1. An electrical connector, comprising:

a metal housing comprising a mating interface;

a first insulating base disposed in the metal housing;

a plurality of first terminals disposed at the first insulating base and comprising at least one pair of first differential signal terminals and at least one first ground terminal;

a second insulating base disposed in the metal housing and being assembled to the first insulating base;

a plurality of second terminals disposed at the second insulating base and comprising at least a pair of second differential signal terminals; and

a partitioning member disposed between the first insulating base and the second insulating base and between the first terminals and the second terminals, the partitioning member being grounded and comprising a partitioning member body and at least one first bump, the first bump being disposed at the partitioning member body, the partitioning member body being at least disposed between the pair of first differential signal terminals and the pair of second differential signal terminals to shield the pair of first differential signal terminals and the pair of second differential signal terminals, the first bump being electrically connected with the at least one first ground terminal;

wherein the partitioning member further comprises a pair of buckling parts; the buckling parts are respectively connected with two opposite side edges of the partitioning member body and extend toward the mating interface;

wherein the partitioning member further comprises a pair of ground end parts; the pair of ground end parts are respectively connected with two opposite side edges of the partitioning member body and the buckling parts; the pair of ground end parts extend in a direction away from the mating interface;

wherein the first bump is disposed at a position connecting the buckling part, the ground end part, and the partitioning member body.
