ABSTRACT:
A retaining member for retaining cylindrical members, such as rods and wires, has a base and a pair of cantilevered dual action beams extending from the base, the beams having parallel opposed spaced apart inner edges, each beam having an upper and a lower portion, the lower portion having an upwardly and inwardly inclined outer edge and the upper part having an upwardly and outwardly inclined outer edge, the conjunction of the two portions forming a neck, and an entrance portion defined by a downwardly and inwardly inclined upper edge on each beam, the upper edges merging with the inner edges by a radius. Insertion of a cylindrical member deforms the upper portions to a large extent the portions bending about the necks. The lower portions are deformed to a lesser extent and have substantially uniform stress distribution. The members are particularly useful as contacts for insulation conductors, the insulation being crushed and during passage between the upper portions of the beams and removed on passage past the necks. The conductor is deformed while being pushed down between the upper portions and past the necks, to give a highly effective connection.
