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 a board-receiving face. An elongated slot is disposed in the board-receiving face generally along a longitudinal axis of the housing for receiving the edge of the printed circuit board. A plurality of pairs of transversely spaced terminal-receiving cavities are disposed on opposite sides of the slot defining two rows of cavities lengthwise of the housing. The pairs of transversely spaced cavities are separated by transverse walls extending generally perpendicular to the longitudinal axis of the housing. A plurality of terminals are received in the transversely spaced cavities. The terminals are in pairs for engaging the contact pads on opposite sides of the printed circuit board. One terminal in each pair is disposed in a respective one of the transversely spaced cavities. Recesses are provided in the transverse walls between the cavities for accommodating carrier strip cutoffs projecting from the terminals. Different length preloading walls are provided in the housing for preloading spring contact portions of the terminals.
