Abstract
An electrical connector assembly including a bilayered elastomeric element of integral construction for providing effective contact force (pressure) between corresponding arrays of conductors located on two circuit members (e.g., one a flexible circuit and the other a more rigid, circuit board or card). High density connections are assured in a sound, effective manner. The elastomer, preferably silicon rubber, includes a base layer with several spaced openings therein and an adjacent layer of several upstanding projections (e.g., cylindrical or box-like) spacedly located relative to the adjacent openings within the first layer. The first layer openings accommodate bulged elastomeric during compression to assist in preventing undesirable elastomeric buckling, thereby assuring the desired contact force (pressure) application.
