• and
• a plurality of terminals arranged in a row along a first direction, wherein the first direction is perpendicular to the front-rear direction, the row of the terminals are provided on the first side wall and have at least one pair of first signal terminals and at least one first ground terminal, at least one adjacent side of one of the at least one pair of first signal terminals is provided with one of the at least one first ground terminal, each of the terminals has an elastic portion extending along the front-rear direction and being free, a front end of the elastic portion is provided on the bottom surface close to front thereof and protrudes into the insertion slot to elastically abut and be electrically connected to the first component, a back end of the elastic portion has an adjusting portion, and the adjusting portion is provided to be behind relative to the bottom surface;
• wherein one of the first separation walls is located between one of the first signal terminals and an adjacent one of the at least one first ground terminal, the one of the first separation walls continuously separates the two corresponding elastic portions thereof backward from a front thereof, none of the first separation walls exists between one of the at least one pair of first signal terminals, the two adjusting portions of the one of the at least one pair of first signal terminals are separated only by a first medium, and a dielectric coefficient of the first medium is less than a dielectric coefficient of each of the first separation walls;
• wherein the first side wall has a first rib extending backward and having a free end, and the free end of the first rib is located between the one of the at least one pair of first signal terminals;
• and
• wherein the front end of the elastic portion of each of the first signal terminals has a contact portion arched toward the insertion slot, a portion of the contact portion protrudes inward into the insertion slot to elastically abut and be electrically connected to the first component, a back end of the contact portion has a transition portion, the transition portion is connected backward to a connecting portion, two opposite inner edges of two adjacent ones of the transition portions of the first signal terminals form a trumpet shape shrinking backward from a front thereof, and the first rib extends backward and does not pass beyond the transition portion.
