描述

The 539663-2 is a crimp tooling component designed for wire barrel termination in electrical connector assembly processes. The tooling is engineered to maintain precise crimp height (CH) and crimp width (CW) dimensions to achieve a target area index (AI) of approximately 80%, which is critical for ensuring proper electrical and mechanical connection quality. Key dimensional parameters include a nominal crimp height of 0.073 inches, crimp width of 0.110 inches, crimper leg taper of 3.0 degrees, and anvil width of 0.109 inches, with a nominal anvil-to-crimper clearance of 0.005 inches. The tooling components (wire crimper and anvil) are manufactured from materials selected to withstand high loads, moderate shock, and the shear loading generated during the plastic deformation and extrusion of the terminal barrel. This crimp tooling is used in production termination processes where dimensional control is critical to minimize flash generation, maintain consistent pull test values, and achieve high throughput in connector assembly operations.
