Sequentially actuated zero insertion force printed circuit board connector

摘要

A sequentially actuated zero insertion force edge board connector is disclosed for receiving printed circuit boards and the like, the contacts of the connector being sequentially cam actuated for engagement with and disengagement from an edge of the printed circuit board. The subject connector has a housing with an elongated board receiving aperture, an elongated contact drive member lying freely at the bottom of the aperture and a cam member movable between the drive member and the aperature bottom. A plurality of contacts are mounted in spaced apart relationship along at least one elongated wall of the aperture. The contacts have a normal position in which they engage the pads of a printed circuit board and are sequentially moved, in at least two groups, by the drive means to an out of engagement position allowing unhampered insertion and withdrawal of a printed circuit board with respect to the connector.
