1633926-7 is a technical reference document for crimp tooling application in wire termination processes. It provides guidance on critical dimensional parameters including crimp height (CH), crimp width (CW), and area index (AI), with a typical design point of 80% AI. The document specifies nominal conditions such as CH of 0.073 in, CW of 0.110 in, crimper leg taper of 3.0 degrees, and anvil width of 0.109 in, with a nominal anvil-to-crimper clearance of 0.005 in. It emphasizes the importance of dimensional control, as small variations in CW (±2%) directly impact CH tolerance, and demonstrates how clearance can increase by more than 50% with cumulative dimensional changes. The material selection for wire crimpers and anvils is critical, as these components must withstand high loads, moderate shock, and shear loading during the plastic deformation and extrusion process.
