Abstract
An interface for connecting coplanar printed circuit ("PC") boards (10, 20) using a flexible jumper circuit (50) for bridging the PC boards (10, 20), a base (80) underlying the second PC board and integrally attached thereto, and a support housing (30) with compression plugs (60) which may be tightened against base (80) for securing the two PC boards (10, 20) and for compressing the flexible jumper circuit (50) against the two PC boards (10, 20). The interface is precision aligned by a plurality of guide pins (34) which protrude from support housing (30) and conform to guide holes in the two PC boards (10, 20) and the flexible jumper circuit (50). Guide pins (34) fix the relative positions of the boards (10, 20) and circuit (50) within their respective planes. The resilient compression plugs (60) maintain contact between the flexible jumper circuit (50) and the two PC boards (10, 20) despite irregularities in thickness, and the guide pins 34 maintain precision horizontal alignment between the contact pads (12, 22) on the two PC boards (10, 20) and the conductive traces (52) on the flexible jumper circuit (50).
