描述

4-690403-2 is a crimp tooling component used in wire termination processes to achieve precise crimping of wire and barrel assemblies. The tooling is designed to maintain critical dimensional parameters including crimp height (CH) and crimp width (CW), which directly influence the area index (AI) performance of the crimp joint. Key design specifications 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 loading and moderate shock during the plastic deformation and extrusion process of terminal barrels. This component is critical for maintaining production quality metrics such as pull test values, crimp symmetry, and consistent area index targets typically set at 80%, making it essential for reliable electrical connections in connector assembly operations.
