DESCRIPTION

7-2151731-7 is a crimp tooling component manufactured by TE Connectivity for wire barrel termination in electrical connector assembly. The tooling is engineered to maintain precise crimp height (CH) and crimp width (CW) dimensions to achieve an optimal Area Index (AI) of approximately 80%, which directly impacts pull test values and termination quality. Key design 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 to minimize flash formation. The tooling components, particularly the 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 terminal barrels. This precision tooling is critical for maintaining consistent crimp quality, lead throughput rates, and process repeatability in high-volume wire termination production environments.
