Abstract

Abstract Two electronic components having fine pitch arrays of terminals can be disconnectably interconnected by a multiple electrical connector that includes a pair of intermeshable members. Each of those members has an electrically insulative body with a structured surface including a plurality of tapered elements. Tapered sides of those elements fit flush against each other when the two members intermesh, and the members become strongly adhered to each other when the tangent of the half angle of said tapered sides is no greater than the coefficient of friction of the material of the contacting surfaces. Each of the members has a plurality of electrically conductive segments in position to make good electrical contact when the members intermesh.
