1-1579007-4 is a crimp tooling component manufactured by TE Connectivity for wire termination and barrel crimping operations. The tooling is engineered to control critical crimping parameters including crimp height (CH) and crimp width (CW) to achieve proper area index (AI) performance, with a typical design point of 80% AI. The component incorporates precision dimensional specifications such as 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 nominal anvil-to-crimper clearance of 0.005 inches. The tooling is constructed from materials selected to withstand high loads, moderate shock, and shear loading during the plastic deformation and extrusion process of terminal barrels. This crimp tooling is essential for maintaining consistent pull test values, crimp symmetry, and production throughput in automated wire termination processes used in electrical connector assembly.
