ABSTRACT:
A multicontact electrical connector comprises an insulating housing having a substrate-receiving face. A trough-like opening extends into the face for reception of a substrate. In the housing are spaced-apart terminals having free ends which are proximate to the substrate-receiving face and fixed ends which are proximate to an inner end of the opening. Contact surfaces are on the free ends for contacting spaced-apart terminal pads on the substrate. Contact engagement camming means are provided for flexing the terminals and moving the free ends from the opening allowing the substrate to be placed in the opening under reduced insertion force conditions. As the free ends of the terminals are subsequently moved, the contact surfaces of the free ends will be resiliently biased against the terminal pads. Contact wipe camming means are provided to move the contact surfaces across the terminal pads as normal force occurs permitting a wiping action to take place. A locking means is provided to hold the substrate in place as the wiping action occurs. This assures that the contact surfaces and the terminal pads, where engagement therebetween takes place, are cleaned and a positive electrical connection is effected.
