Contact structure employing an elastomeric connector

A circuit assembly comprising:

• a one-piece molded support member having first and second planar support surfaces which extend parallel to one another, with both of said planar support surfaces facing in the same direction;
• a first circuit device positioned on said first planar support surface and having a row of first contact elements formed to have contact surfaces all lying in a first common plane;
• a second circuit device having a first planar surface and having a row of second contact elements disposed on said first planar surface and formed to have contact surfaces all lying in a second common plane, said second circuit device being secured to said support member such that said first planar surface of said second circuit device bears against said second planar support surface and said contact surfaces of said second contact elements face said contact surfaces of said first contact elements, each first contact element is aligned with a respective second contact element, and said first and second common planes are parallel to one another and are spaced a predetermined distance apart;
• and an elastomeric connector interposed and compressed between said first and second circuit devices for conductively connecting each first contact element to the respective second contact element with which said first contact element is aligned, wherein said support member has two projecting parts each having an outer surface consisting a part of said second support surface, and said support member further has a third planar support surface located to extend alongside and parallel to said row of second contact elements when said second circuit device is secured to said support member, said third support surface being at least approximately coplanar with said second support surface and being located to oppose warping of said row of second contact elements;
• wherein said support member is molded in a mold having two mold halves and said first and second support surfaces are formed by one of the mold halves;
• wherein said support member has two projecting parts each having an outer surface constituting a part of said second support surface;
• and wherein each said projecting part has a tapped opening and further comprising threaded connectors engaging in said tapped openings for securing said second circuit device to said projecting parts.
