ABSTRACT:
An electrical connector for a flat circuit-bearing element, such as a calculator display element, is constructed to hold the element at an angle with respect to a supporting surface. The element is initially inserted into the connector at an angle and rotated into a mating position so that insertion force is low and contact force is high in the mating position. In one embodiment the connector is constructed to hold the element at a fixed angle with respect to a supporting surface, while in another embodiment the connector includes a rotatable element holding member which permits selective angular disposition of the element within certain limits of angular position of the rotatable member. Each embodiment includes camming ramps directed toward an element retaining recess for positive location of the element in the mating position. A retaining member movably or pivotally secured on the arms of the holding member is pivoted to permit insertion of the element between the arms and is then pivoted back to retain the element between the arms.
