1958080-1 is a wire terminal ring tongue connector designed for 2/0 aluminum wire applications. The terminal features a sealed copper body (ASTM-B187 annealed) with brass inserts and funnel (MIL-C-50), both nickel-plated to provide corrosion resistance and reliable electrical contact. The body is nickel-plated with a minimum thickness of 0.0003 inches per QQ-N-290 specification, while the inserts and funnel receive an average nickel plating thickness of 0.0003 inches. Key dimensional specifications include a maximum funnel diameter of 0.78 inches, a body diameter of 0.911 inches maximum, and an insert diameter of 0.1287 ± 0.015 inches. This terminal is commonly used in high-current electrical connections for power distribution and industrial applications where secure, low-resistance connections are essential.
