Shur-Plug receptacle, 15.5-20 AWG
The 141456-1 is a female receptacle (socket) terminal in TE Connectivity's Shur-Plug wire-to-wire connector series, accepting 15.5-20 AWG wire. The tin-plated brass contact mates with the corresponding Shur-Plug male pin; the fully insulated red nylon housing covers the crimp barrel and extends 0.984 in (25.00 mm) overall.
Wire gauge and insulation fit
The 0.130 in (3.30 mm) insulation diameter accommodates the 15.5-20 AWG wire range — the crimp barrel and wire seal are sized for that bundle, not for thinner or thicker jackets.
