ABSTRACT:
A low insertion force actuable interface assembly having a carrier mounting an array of electrical contacts and a carrier moving means. The carrier moving means has at least one movable cam member guided for movement in a substantially straight line. The cam member has first and second cam portions for guiding a cam follower. The cam follower in following the first cam part causes the carrier to move the contacts parallel with the axes thereof. A first cam part, connected to the carrier, forces a second cam part, connected for movement with the cam member, to move the carrier substantially transverse to the axes of the contacts while the cam follower follows the second cam portion. The guide means comprises at least one first bearing on the cam member, and at least one second bearing on the cam member. At least one first bearing and at least one second bearing are provided, each being provided oppositely facing on the cam member. At least one first roller is positioned for supporting and rolling along the first bearing and at least one second roller is positioned for supporting and rolling along the second bearing. An interlocked interface is provided between the first roller and the first bearing for substantially preventing movement of the cam member in a transverse direction. The first and second rollers support and guide the cam member along a substantially straight line.
