<p>An electrical connector in which two rows of resilient contacts are mounted in a connector housing on opposite sides of a slot which is adapted to receive a printed circuit board or similar electrical component therein. The end portion of the spring contacting section of each contact is reversely bent in a direction away from the slot. A vertically movable contact shifting element is disposed between the spring contacting sections and the reversely bent end portions of the contacts in each row of contacts. A cam actuator is operated to move the contact shifting elements upwardly against the reverse bent end portions of the contacts thereby deflecting the spring contacting sections away from the slot so that a printed circuit board may be inserted therein with zero insertion force. Teeth are provided on the contact shifting element and cam actuator which interlock and thereby restrict upward movement of the contact shifting element except during operation of the cam actuator.</p> |
