A connector for mounting and electrically connecting a chip carrier unit in an electrical circuit has a plurality of electrical contacts secured in openings in the bottom of an electrically insulating body to permit cantilever spring deflection of the contacts in accommodating a chip carrier unit within the connector between the contacts. The contacts comprise wire members of round cross section each having an opposite end bent to be slidable along a narrow line of engagement with an inclined ramp surface on an adjacent side wall of the connector body. Each contact has a bowed portion intermediate the contact ends which is bowed away from the adjacent ramp surface to slidably engage terminals on the chip carrier unit as the unit is inserted into the connector. Engagement with the chip carrier terminals permits selected flattening of the bowed portions of the contacts and sliding of the opposite contact ends on the adjacent side wall ramp surfaces to provide simple beam spring deflection of the contacts in combination with the cantilever spring deflection, thereby to provide a force for resiliently engaging the chip carrier terminals.
