Abstract
A connection system requiring little or no force to mechanically and electrically connect a printed circuit board to a flexible printed circuit. The connection system includes a flat and rigid carrier having an upper surface upon which is affixed a flexible printed circuit having an electrically conductive raised area in the form of a plurality of raised dots. At the upper surface, the carrier has a groove formed therein, wherein the raised dots are located in the groove. An elastomeric insert is situated in the groove in abutting relation to the flexible printed circuit behind the raised dots. A rigid printed circuit board has an electrically conductive area in the form of a plurality of pads. The printed circuit board is inserted into the groove, whereupon the elastomer resiliently compresses so as to press the plurality of raised dots into tight electrical contact with the plurality of pads. In a first preferred embodiment the printed circuit board is inserted vertically with slight force. In a second preferred embodiment, the printed circuit board is inserted at an acute angle with zero insertion force and then rotated to the vertical.
