Abstract
Abstract A spring array connector includes a unitary resilient layer of multiple springs having a layer of multiple electrically conducting lines, electrical contacts and electrical terminals. Each spring of the array is independently bendable and each of the conducting lines is electrically isolated from the other conducting lines. All of the springs in the spring array are fabricated simultaneously. Spring embodiments include sine, helix, cantilever and buckling beam shapes in sheet and wire forms.
