Claim:
1. A electrical connector comprising: an elongate insulative housing including a top wall, a bottom wall opposite to each other and a pair of end walls respectively connecting two ends thereof, and a receiving cavity surrounded thereby; a terminal assembly received in the top wall and the bottom wall respectively, and stacked in an up-to-down direction; and a metal case enclosing the insulative housing; wherein the terminal assembly includes a signal terminal group, and a ground terminal group including a first contact portion and a second contact portion, wherein the first contact portion and the second contact portion are arranged in a front-to-back direction perpendicular to both the up-to-down direction and an elongate direction, and respectively protruding into the receiving cavity; wherein the signal terminal group includes a third contact portion protruding into the receiving cavity, and a front end of said first contact portion is in line with a front end of the third contact portion in the elongate direction but the second contact portion protrudes forward over the first contact portion in the front-to-back direction; wherein each of the signal terminal group or the ground terminal group includes a main body from which the corresponding first contact portion, second contact portion or third contact portion extends, wherein the first contact portion in the receiving cavity is higher than the second contact portion when protruding upwardly into the receiving cavity, but lower than the second contact portion when protruding downwardly into the receiving cavity, while the second contact portion in the receiving cavity is in line with the third contact portion disregarding whether the second contact portion protrudes upwardly or downwardly; wherein the ground terminal group includes a first ground terminal containing said first contact portion and a second ground terminal containing said second contact portion, and the first ground terminal and the second ground terminal commonly received in one terminal passageway defined by the top wall or the bottom wall; wherein the second ground terminal is either equipped with a spring contact portion extending from the main body for flexibly abutting against the metal case, or the main body of the second ground terminal directly electrically contacts with the metal case.
