Electrical connector utilizing contact array

An electrical connector assembly comprising:

• a printed circuit board having a plurality of conductive pads on an upper surface thereof;
• a substantially rectangular insulating housing retainably seated upon said upper surface, said housing defining a plurality of passageways extending between opposite middle and bottom faces of said housing and through the bottom face;
• a plurality of resilient contacts disposed in the corresponding passageways, respectively;
• a receiving slot defined in the housing and communicating with an exterior, through an opening in a front face of the housing, in a direction parallel to said printed circuit board;
• and
• each of said contacts defining opposite upper and bottom ends, said bottom ends downwardly extending beyond the bottom faces, and said upper end upwardly extending above the middle face and into the receiving slot;
• wherein
• the bottom end mechanically and electrically engages the corresponding conductive pad, and the upper end is adapted to be mechanically and electrically connected to a thin substrate which is received in the receiving slot wherein each of said contacts defines a loop-like capsular shape snugly and compliantly received in the corresponding passageway with two opposite side arms of the capsular shape abutting against corresponding inner faces of the corresponding passageway when the thin substrate has not been inserted into the receiving slot and said contact is in a relaxed manner.
