1-456134-4 is a technical reference document for crimp tooling used in wire termination and connector assembly processes. The document details critical dimensional parameters including crimp height (CH) and crimp width (CW), which directly influence the Area Index (AI) metric—a key quality indicator defined as the ratio of total crimped area to total uncrimped area, with a typical design point of 80%. The tooling 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 a nominal anvil-to-crimper clearance of 0.005 inches. Material selection for critical components such as wire crimpers and anvils is emphasized, as these must withstand high loads, moderate shock, and significant shear loading during the plastic deformation process. This guidance is essential for manufacturers seeking to maintain consistent crimp quality, minimize flash generation, and optimize production throughput while ensuring reliable electrical and mechanical connections.
