ABSTRACT:
A miniature circuit board edge connector having a very short electrical contact path is taught. Briefly stated, an insulative housing has contained therein a resiliently flexible and electrically conductive contact. A camming device is disposed in the housing and impinges upon the contact and through lateral motion of the cam, urges the contact vertically downward so as to cause downward and outward movement of a portion of the contact with respect to the housing which thereby comes in contact with an electrically conductive path on a daughter board which is adjacent thereto. A portion of the contact is in slidable electrical communication with a conductive post which is mounted in the base of the connector assembly and attached to a mother circuit board. The electrical path between the daughter board circuit board and the mother board conductive post through the contact is very short and in a slightly arcuate manner and minimizes inductive, capacitive and propagation delay effects.
