Patent ID: 7938648

Claim:
An electrical connector mounted on a printed circuit board having through holes thereof, comprising: an insulative housing defining a mounting face for mounting onto the printed circuit board and a mating face opposite to the mounting face; a plurality of contacts received in the insulative housing and extending from the mounting face to the mating face; an insulator mounted to an underside of the printed circuit board and forming a plurality of pairs of guiding posts extending from opposite sides thereof; a metallic back panel attached to the insulator and defining a plurality of holes to receive corresponding guiding post of the insulator; and a plurality of fastening elements mechanically interconnecting said back panel, said insulator and said insulative housing onto opposite sides of the printed circuit board after said pairs of guiding posts of the insulator are retained to the metallic back panel and the printed circuit board; wherein the insulator forms a plurality of latches around a periphery thereof to securely grip the metallic back panel and to be sandwiched between the printed circuit board and the metallic back panel; wherein the insulator and the metallic back panel define a plurality of through holes for insertion of the fastening elements; and wherein the guiding post of the insulator is located between an adjacent through hole and an adjacent latch in a lengthwise direction of the insulator.
