DESCRIPTION

7-2151251-7 is a crimp tooling component used in wire termination and barrel crimping processes. The tooling is designed to maintain precise crimp height (CH) and crimp width (CW) parameters that directly affect the Area Index (AI), a critical quality metric defined as the ratio of total crimped area to total uncrimped area, typically targeted at 80%. Key dimensional specifications include 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 components (wire crimper and anvil) are manufactured from materials selected to withstand high loads, moderate shock, and significant shear loading during the plastic deformation and extrusion process. This crimp tooling is essential for maintaining production quality, controlling flash generation, and ensuring consistent pull test values and crimp symmetry in high-volume wire termination operations.
