Electrical connector with improved inserting member

An electrical connector comprising:

• an insulating housing having a mating face, a card slot recessed from the mating face with a floor face facing the mating face, and two side walls located at opposite sides of the card slot, each of the side walls defining a plurality of signal passageways and a plurality of grounding passageways;
• two rows of terminals located on the side walls, each row of terminals comprising a plurality of signal terminals in the signal passageways and a plurality of grounding terminals in the grounding passageways, each terminal comprising a retained portion retained in the insulating housing and an elastic arm with a contacting portion extending into the card slot;
• a one-piece inserting member assembled in the insulating housing, the inserting member defining a plurality of first inserting portions in the signal passageways and made from insulating plastic, and a plurality of second inserting portions in the grounding passageways and at least partly made from conductive plastic, the second inserting portions mechanically connecting corresponding grounding terminals respectively;
• and
• a metallic member retained in the inserting member between the two rows of terminals;
• wherein the metallic member defines two rows of grounding fingers, the grounding fingers are located in corresponding second inserting portions respectively, and the grounding fingers directly connect or face but not directly connect with corresponding grounding terminals respectively.
