Abstract: A system for providing low insertion force electrical interconnections between high density contacts for use in interconnecting circuit packages. A housing has disposed therein one or more pre-buckled beam connectors. Each connector has a resilient insulating strip carrying a plurality of buckling beams electrically isolated from each other. The beams are aligned on the plane defining the strip in parallel with ends extending away from the strip edges in opposing directions. Means are provided for deforming the strip within the housing prior to effecting desired interconnections whereby the beams are pre-buckled. Upon urging contacts into proximity with the beam ends, the buckling force is released causing each beam's ends to be urged away from the strip into engagement with respective contacts, thereby effecting desired interconnection between contacts and through one or more beams.
