Building a Decision Support System for Students by Using Concept Maps

A zero or low insertion force electrical connector is provided by a pair of elements which may be fitted together along a longitudinal insertion axis, and then engaged in edge contact relationship at at least two points by a relative pivoting movement. The elements may be fabricated of relatively thin sheets, and have a total thickness corresponding to only two thicknesses of the material. Connectors in accordance with the invention may be made of identical or dissimilar elements, and may include means for preventing out-of-plane shifting of one element relative to the other. Because of the thin edge profile, the elements may be densely packed in a multiple connector, and because of the hinging action the connectors may provide structural support for circuit boards or conductors to which they are coupled, or enable access to circuits for testing under an applied voltage.
