Abstract
A female contact (40) is formed by a plate and has a contact section (46) in the front, a retention section (44) in the midst and a biased tail (45) in the rear. The contact section (46) includes a front ring (41) and a rear ring (42) positioned at two opposite ends thereof, and three beams (431, 432, 433) spaced apart from and parallel to each other, and integrally connected between the front ring (41) and the rear ring (42), respectively. These three beams (431, 432, 433), including a base beam (432) and a pair of auxiliary beams (431, 433) positioned above the base beam (432) within an appropriate angle range relative to the vertical line (L1) of the base beam (432), are inward bowed to each other proximate the middle portion wherein each beam (431, 432, 433) has itself an identical width along its length while the width of the base beam (432) is relatively larger than that of the auxiliary beams (431, 433).
