ABSTRACT:
A zero insertion force card edge connector for mounting on a backplane and receiving therein a daughter card whereby circuits on the backplane and card are electrically interconnected through contact members in the connector. More particularly, the connector includes cam members, slidably mounted between an upper and lower housing for driving spring arms on the contact members into engagement with conductive pads on thedaughter card. The cam members further move the upper housing downwardly, in cooperation with the spring arms which are preloaded in the connector, to remove restraining members which otherwise restrain the spring arms from entering the card slot and engaging the conductive pads.
