Abstract:
1. A card edge connector assembly comprising: a printed circuit board defining a through opening extending through opposite upper and lower surfaces of said printed circuit board in a vertical direction and circumferentially bounded by corresponding edge sections of the printed circuit board essentially composed of opposite front and rear edge sections and opposite side edge sections; an elongated insulative housing defining a horizontal card receiving slot located between opposite upper and lower walls in a longitudinal direction perpendicular to said vertical direction, and forwardly communicating with an exterior in a front-to-back direction perpendicular to both said longitudinal direction and said vertical direction; a plurality of upper contacts disposed in the upper wall with resilient upper contacting sections extending into the card receiving slot and upper tail sections soldered to the printed circuit board around the rear edge sections; and a plurality of lower contacts disposed in the lower wall with resilient lower contacting sections extending into the card receiving slot and lower tail sections soldered to the printed circuit board around the front edge sections; wherein a lower portion of the lower wall of the housing being a fitting portion, is disposed and fully circumferentially surrounded in the through opening; wherein the housing forms a pair of step structures by two lateral sides of the fitting portion to be downwardly seated upon the upper surface of the printed circuit board around the corresponding side edge sections; wherein the lower wall defines a plurality of lower passageways configured to have the lower contacts rearwardly assembled thereinto in said front-to-back direction.
