Ribbon cable connection method to LCD circuit board tracks - uses conductive pads on cable fitting between insulating pads on circuit board to make contact with respective tracks

Abstract

Abstract The arrangement uses a ribbon cable (12) of 'flexible pcb' form which makes contact with conductive tracks (11) carried on a substrate (10), esp. that of a matrix type liquid crystal display. A set of conductive pads (21) is positioned on the end of the band, each pad being in contact with a corresponding conductor wire. A second set of pads, of insulating material, is positioned on the substrate between the conductive tracks. When the band of cable is brought to the substrate the insulating pads of the substrate hit between the conductive pads of the cable. At each edge of the cable band there is a pad of greater width than normal, which prevents the cable being fitted to the substrate in the wrong position. A spring element is provided to maintain the ribbon of wires pressed against the substrate.
