ABSTRACT The present invention features a daughter board connector that has an arrangement to apply a translational force between the daughter board connector contacts and the backplane contacts without gripping the contacts. The daughter board is thus mounted on the backplane with a very low insertion force; there are high normal forces between the connector contacts and the backplane contacts after the translational force is applied, and because of the simple nature of the mechanism, a large number of contacts can be placed in a small area. The arrangement to apply a translational force may comprise a slidable cam plate that moves the connector contacts in a direction parallel to the backplane, the connector having one or more guide pins for mating with holes on the backplane. The cam plate moves free ends of daughter board contacts prior to mounting on the backplane, and the free ends are released to resiliently engage the backplane contacts. The free ends are prestressed during manufacture and the backplane contacts are plated- through holes of the backplane. In another embodiment the arrangement to apply a translational force is a cam that moves the connector relative to the backplane after the connector has been mounted on the backplane.
