  • Patent number: 7081014
    Abstract: An electrical connector adapted for mounting on a Printed Circuit Board (PCB), comprises an insulative housing, a plurality of terminals loaded in the insulative housing and a board lock device assembled in the insulative housing. The insulative housing comprises a base portion having a PCB mounting face and a mating portion extending from the base portion. The base portion defines a boardlock-receiving cavity and is formed with a block adjacent to the cavity. The board lock device comprises a retaining plate retained in the cavity and substantially parallel to the PCB mounting face of the base portion and a lock plate perpendicularly extending from the retaining plate beyond the PCB mounting face of the base portion for locking with the PCB. The retaining plate is supported by the block for preventing the board lock device from moving along a direction perpendicular to the PCB mounting face of the base portion.
