Abstract
An improved low insertion force connector assembly is described for mounting printed circuit boards and the like in a receptacle in which the contacts are cam actuated between open and closed positions to achieve a zero or low entry force. A daughter board header is attached to a daughter printed circuit board to make a two-part connector. A combination cam actuator rod and card guide is fixedly mounted on an associated equipment frame and serves to guide the circuit board into the connector receptacle. The receptacle housing of the subject connector is fixed to a mother printed circuit board and has an elongated board receiving aperture, an elongated contact drive member lying freely in the bottom of the aperture, and an elongated cam arranged to rotate between the drive member and the aperture bottom to move the former with respect to the latter. A plurality of contacts are mounted in spaced apart parallel arrangement on both elongated walls of the aperture and are moved into and out of engaging positions by the cam driven contact drive member. The daughter board header includes a like plurality of parallel spaced contacts which are fully supported on a first end to engage in the low insertion force connector and form spaced pairs of members for fixedly engaging printed contact pads on the opposite sides of a daughter printed circuit board where they are preferably soldered to the respective circuit pads. Mechanical needs are also provided to fix the daughter board header to the daughter board. The combination cam actuator rod and card guide is arranged to be secured to a portion of the equipment frame adjacent one end of the connector and includes linkages to be attached to the cam actuator portion of the low insertion force connector. Thus the printed circuit board provided with the daughter board header can be inserted into the low insertion force connector and secured therein by movement of the actuator rod from a remote location.
