A low insertion force connector for making electrical connection between electrical contacts on a printed circuit board assembly and external circuitry, and having an improved linear cam actuating mechanism is described. An elongated outer housing having a centrally located opening with a longitudinal channel along the bottom thereof, has spaced apart ramps positioned at the bottom of the channel. The housing has an aperture at each end thereof, and has external ramps on each end of the outer housing in a predetermined relationship to the associated aperture. A plurality of contacts are mounted within the outer housing on either side of the channel, with first ends interior the housing being bowed inwardly for contacting the printed circuit board assembly, and second ends extending through said outer housing for making electrical connection to external circuitry. An elongated cam actuator having grooves along the sides thereof, has a bottom surface configured to mate with the ramps at the bottom of the channel, and is of a length sufficient to extend through both of the apertures in the ends of said outer housing. The cam actuator has mating ramps configured to cooperate with the external ramps. An inner shell is slideably mounted to the cam actuator and is positioned in the opening in the outer housing. The inner shell has upright members for engaging the contacts and forcing them to move laterally out of contact with printed circuit board assembly when the cam actuator engage the external ramps and force the shell downwardly.
