Electrical connector with high frequency performance

A terminal module comprising:

• an insulating housing with two opposite vertical sides;
• a row of terminals retained in the insulating housing, each terminal comprising a contacting portion extending out of a front end of the insulating housing, a tail portion extending out of a lower end of the insulating housing, and a middle portion between the tail portion and the contacting portion, the middle portion being embedded in the insulating housing, the row of terminals comprising at least two grounding terminals and one pair of differential terminals between the at least two grounding terminals;
• and
• an absorbing member being attached to one vertical side of the insulating housing to cover at least partially of the middle portions of the terminals;
• wherein the absorbing member has no contact with the terminals, and a distance between two nearest sides of the absorbing member and the middle portion is greater than 0.3 mm.

A terminal wafer comprising:

• an insulative housing;
• a row of terminals retained in the insulative housing, each terminal comprising a contacting portion extending out from a front end of the insulative housing, a tail portion extending out from a bottom end of the insulative housing, and a middle portion between the contacting portion and the tail portion and embedded in the insulative housing, the row of the terminals comprising plural pairs of differential terminals and plural grounding terminals alternately arranged;
• and
• a shielding member and an absorbing member;
• wherein the shielding member comprises plural shielding portions located at a vertical side of the insulating housing to align with and shield the plural pairs of differential terminals and plural grounding fingers contacting with corresponding grounding terminals;
• and
• wherein the absorbing member is attached to the shielding member and at least partially covers the shielding member.
