Edge connector for a printed circuit board

摘要

A push-pull edge card electrical connector is adapted for receiving an edge of a printed circuit board having contact pads on opposite sides of the board adjacent the edge. The connector includes an elongated dielectric housing having an elongated slot for receiving the edge of the printed circuit board. A plurality of first and second alternating terminal-receiving cavities are spaced along at least one side of the slot and separated by transverse walls extending generally perpendicular to the longitudinal axis of the housing. The cavities are disposed between longitudinal side walls of the housing and a reinforcing rib extends across and joins the transverse walls of at least some of the cavities generally adjacent the slot. A first press-fit recess is located generally adjacent but spaced from one of the longitudinal sidewalls of the first cavities and a second press-fit recess is located generally adjacent but spaced from the reinforcing rib within the second cavities. A plurality of first and second terminals are provided with each first terminal received in one of the first terminal-receiving cavities and each second terminal is received in one of the second terminal-receiving cavities. Each of the terminals includes a base portion having a retention section press-fit within the press-fit recess of its respective cavity.
