Electrical connector with improved high frequency performance

An electrical connector comprising:

• an insulating housing;
• and
• a plurality of terminals retained in corresponding terminal grooves;
• wherein the terminals comprise a row of grounding terminals arranged along a first direction and plural rows of functional terminals at each side of the row of grounding terminals, each grounding terminal comprises a vertical main portion and an upper resilient arm, the main portion has an upper cutting face and a lower cutting face along a thickness direction thereof, the upper resilient arm extends upward and leftward from the upper cutting face for abutting against the main portion when the upper resilient is pressed, each functional terminal comprises a retaining portion and two elastic arms extending from the retaining portion, and a center line of each of the functional terminals is perpendicular to a plane where the grounding terminals are located.

An electrical connector comprising:

• an insulating housing;
• and
• a row of grounding terminals arranged in a first direction, a first functional region and a second functional region being arranged at opposite sides of the row of grounding terminals, each of the first functional region and the second functional region comprising rows of functional terminals, each of the functional terminals comprising a retaining portion and two elastic arms extending from opposite ends of the retaining portion;
• wherein the elastic arms of the function terminals in the first functional region extend toward the row of the grounding terminals, and the elastic arms of the function terminals in the second functional region extend toward the row of the grounding terminals and directly opposite to the elastic arms of the function terminals in the first functional region.
