Power connector with rotary cam for daughter card

摘要

A power connector for distributing power to an active edge of a daughter card which is insertable into a channel of the power connector, includes a plurality of terminals electrically connected to a power source. A cylindrical cam shaft within a longitudinal aperture of the connector housing is rotatable upong actuation to deflect cantiliver beam portions of the terminals into the card-receiving channel to engage contact sections of the daughter card along the active edge and power the card. The cantilever beams extend through transverse profiled apertures of the cam shaft into recesses along the channel and are cammed into the channel and against card contacts by being engaged by inwardly facing wall surfaces of the profiled aperture upon actuation. The beams may also be similarly cammed out of card contact engagement by opposed inwardly facing camming wall surfaces of the profiled aperture engaging the beams when the cam shaft is rotated in the opposite direction to disengage from the card's contact sections and clear the channel allowing withdrawal of the card from the channel. A return path terminal for the connector has a raised contact section to be the first terminal to engage a card contact section and to be the last to disengage.
