Card edge connector with board retention means

摘要

An electrical card edge connector for electrically connecting daughter boards of different thickness to a circuit board, comprises an insulative housing having a slot for receiving the daughter board therein, and a pair of spaced towers respectively adjacent to opposite ends of said slot wherein each tower further includes a pair of spaced rails for guiding the insertion of the daughter board into the slot, and a receiving portion defined above the rails by an interior wall and a pair of spaced stop walls. A rotatable first retention means is located at a top end of each tower for rotatably moving to vertically and releasably retain the daughter board inserted into the slot. A second retention means includes an attachment portion for retaining the second retention means within the receiving portion of each tower, and a pair of spaced spring arms supported by the stop walls to horizontally and elastically clamp the inserted daughter board therebetween. By means of the first and second retention means, daughter boards of different thickness are provided with sufficient and reliable multi-directional retention within the slot of the housing.
