ABSTRACT:
An electrical connector in which two rows of resilient contacts are mounted in a connector housing which is adapted to receive therein conductors on an electrical component that are desired to be engaged by the contacts. The contacts have spring contacting portions which extend resiliently toward a center wall in the housing. Means is provided for retracting the contacts away from the center wall so that the conductors on the electrical component may be inserted into the connector housing with zero insertion force. Such retracting means includes laterally extending fingers pivotally connected to the center wall. The contacting portions of the contacts extend through vertical openings in the fingers. A cam actuator underlies the ends of the fingers. Longitudinal movement of the cam actuator raises the fingers, whereby the contacts are cammed outwardly away from the center wall in the housing.
