摘要

An electrical connector socket includes an insulation base, a tongue piece and a detection terminal. The insulation base includes a stopping surface. The tongue piece includes a side wall vertically extending from the stopping surface. The detection terminal includes a fixed end embedded into the insulation base, an elastic arm extending from the fixed end in a curved manner with its concave surface facing the side wall, and a contact section continuously extending from the elastic arm in a curved manner with its convex surface facing the side wall.
