ABSTRACT:
A solderless surface mount card edge connector is presented. In one embodiment, a connector is attached to a printed circuit board 53. The connector includes a plurality of contacts and extrusions. A daughter board includes a rigid portion on which are attached a series of fingers. When the rigid portion of the daughter board is placed within the connector, the plurality of contacts are pressed downward and establish electrical contact with electrical regions on the mother board. Also, the downward force is transferred by the contacts into horizontal pressure so that electrical contact is established between the plurality of contacts and the series of fingers. In order to maintain the pressure two metal threaded spacers are pinned to the daughter board and fastened to the mother board via screws. Once tightened the assembly is protected from dislodging, even under vibration. The downward pressure, and thus electrical contact, is maintained. The screws may be undone to separate the mother board from the daughter board.
