Patent ID: 7144270

Claim:
An electrical connector for a flexible printed board, the flexible printed board having an end portion that has a first surface mounted with a flexible insulating seat thereon, and a second surface opposite to the first surface, an assembly of the flexible printed board and the insulating seat being formed with an opening unit, the second surface being formed with a plurality of conductive contacts aligned in a transverse direction of the flexible printed board and disposed adjacent to the opening unit in the assembly of the flexible printed board and the insulating seat, said electrical connector comprising: a mounting block having a base portion that has an abutting surface adapted to face the second surface of the flexible printed board and formed with a plurality of parallel receiving slots adapted to correspond respectively to the conductive contacts on the second surface of the end portion of the flexible printed board, and a projecting portion projecting from said abutting surface of said base portion, adapted to pass through the opening unit in the assembly of the flexible printed board and the insulating seat, and formed with a plurality of open-ended positioning grooves that correspond respectively to said receiving slots; and a plurality of resilient clamp-shaped terminal pieces mounted on said mounting block, each of said terminal pieces having a contact section received in a respective one of said receiving slots and having a connecting end portion extending outwardly of the respective one of said receiving slots, and a contact end portion opposite to said connecting end portion and adapted to be in electrical contact with a corresponding one of the conductive contacts of the flexible printed board, and an anchoring section having a coupling end portion extending from said connecting end portion of said contact section and adapted to extend through the opening unit in the assembly of the flexible printed board and the insulating seat, a free end portion opposite to said coupling end portion and disposed outwardly of said projecting portion of said mounting block, and an intermediate portion interconnecting said coupling end portion and said free end portion and extending through a corresponding one of said positioning grooves in said projecting portion of said mounting block so as to clamp the insulating seat, the flexible printed board and said mounting block between said contact section and said anchoring section of each of said terminal pieces, said free end portion extending from said intermediate portion toward said contact section so as to prevent removal of said mounting block from each of said terminal pieces.
