Abstract
Apparatus for interconnecting a printed wiring board (10) and an electrical module carrying board (50) with zero insertion force. Conductors (15) permanently connected to the PWB (10) and extending substantially at right angles therefrom, pass freely through insulative actuator plate means (20, 21) and then extend freely through the plated-through holes (52, 53) of the module board (50). Manually operable cam means (37, 46, 49, 33, 35) are provided which cause opposite lateral movement of the actuator plate means (20, 21). The actuator plate means (20, 21) in turn act against the conductors (15) to cause their flexure into electrical contact with the walls of the plated-through holes (52, 53) of the module board (50).
Claims3
Electrical interconnection apparatus for removably connecting a plurality of circuit modules to a first electrical circuit board having printed wiring affixed on a surface thereof comprising
- a second electrical circuit board in substantially parallel, spaced-apart relation to said first board, said second board having said plurality of modules permanently affixed thereto and having a first and a second array of plated-through apertures in electrical connection with said plurality of modules,
- a first and a second array of flexible conductors electrically connected to the printed wiring of said first board, said arrays of conductors permanently attached to and extending outwardly from said first board to pass freely through said first and second array of apertures, respectively,
- a first and a second insulative actuator plate laterally operable on said first and second array of conductors, respectively, for flexing said conductors of each of said arrays of conductors into electrical contact with said plated-through apertures of said first and second array of plated-through apertures, respectively, said first and second actuator plates each being spaced apart from said first board and from said second board such that said arrays of conductors are flexed but not deformed by the operation of said first and second actuator plates, each of said actuator plates having a slot formed therein in alignment with a slot in the other plate, and
- cam means rotatable in said slots for laterally moving said actuator plates.
