3-456401-4 is a crimp tooling component used in wire termination processes to form electrical connections between wires and terminal barrels. The tooling is designed to achieve precise crimp height (CH) and crimp width (CW) dimensions that maintain an 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 must withstand high shear loads and moderate shock during the plastic deformation and extrusion of the terminal barrel. This crimp tooling is essential for production environments where consistent crimp quality, pull test values, and lead throughput rates must be maintained across high-volume wire termination operations.
