Abstract

A scissors-type crimping tool for crimping a female contact onto an electrical conductor, comprising a planar base member having body and first lever portions; an annular crimping die member connected for rotation between die-open and die-crimping positions relative to the base member body portion; a toggle link arrangement connecting a second lever for pivotal movement relative to the base member body portion; and a cascade spring arrangement operable by the toggle arrangement from a non-stressed condition to a stressed caged condition during initial movement of the second lever in the closed direction, and to a stressed condition during further movement of the second lever, thereby to afford processing of different cross-sections of ferrules and conductors in the crimping die, and to apply the force of the stressed cascade spring arrangement to the crimping die member during the final stage of the crimping operation.
