  • Patent number: 7485016
    Abstract: A female terminal with guiding piece includes a tubular body having two lateral walls and two vertical walls, a connecting part, two spring pieces and two guide pieces. Each vertical wall is a single panel wall having a rectangularly-shaped cutout formed therethrough. The cutout is defined between a front side wall edge and a rear side wall edge and between opposing disposed-apart side wall edges extending in the depth direction between the front side wall edge and rear side wall edge. A respective one of the spring pieces is integrally connected to a respective one of the rear side wall edges and extending inwardly into the tubular body. The guiding pieces are bent inwardly from the vertical walls into the tubular body.
