Abstract
A film circuit connector in which respective conductive tracks in film contact areas on front, mating faces are pressed together into electrical connection between side walls of a metal channel-section receptacle spring and a compressible elastomeric plug spring which engage respective rear faces of the films, the compressible plug spring providing a counter-force to the receptacle spring force, accommodating any variations in receptacle spring force arising longitudinally thereof, ensuring constant contact force between all tracks. Tabs for anchoring and grounding the receptacle spring to the circuit board are struck out and bent down from opposite walls of the receptacle spring, enabling electrical shielding of contact areas. Linking portions of conductive tracks connecting the mating contact portions on the front face of the film to board connecting portions, are formed on the rear face of the film for electrical and mechanical protection and may be insulated on all sides. Film positioning and clamping members in the receptacle locate end film portions inwardly minimizing occupation of board space.
