Abstract:
1. A female terminal with guiding piece, comprising: a tubular body having two lateral walls facing in a height direction and opposing to each other and two vertical walls facing in a width direction perpendicular to the height direction and opposing to each other, and extending in a depth direction perpendicular to both the height direction and the width direction; a connecting part being aligned with the body on a rear side in the depth direction and integrally connected with the tubular body; and two spring pieces, each spring piece having a fixed end and a free end disposed opposite the fixed end, the fixed end and the free end integrally connected to each other at an apex to define a V-shaped configuration as viewed in cross-section, wherein 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, both the front side wall edge and the rear side wall edge extending in the height direction 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 being integrally connected to a respective one of the rear side wall edges at the fixed end with the free end extending into the tubular body; and each vertical wall having a guiding piece at the front end in the depth direction thereof, said guiding pieces being plate pieces bent inward from the vertical walls into the tubular body to cover a space between the front ends in the depth direction of said vertical walls and the free ends of the spring pieces, the guide pieces forming a first male terminal receiving channel therebetween, the first male terminal receiving channel tapering inwardly into the tubular body toward the connecting part and terminating in a guide piece opening defined by facially-opposing respective guide piece ends separated from one another by a guide piece distance Dgp; respective ones of the free ends of the two spring pieces forming a second male terminal receiving channel therebetween, the second male terminal receiving channel disposed interiorly of the tubular body and tapering inwardly into the tubular body toward the connecting part, the second male terminal receiving channel having a frontward spring piece opening disposed adjacent the guide piece opening and defined by facially-opposing respective tips of the free ends of the two spring pieces separated from one another by a frontward distance Df and a rearward spring piece opening defined by facially-opposing apexes of the two spring pieces separated from one another by rearward distance Dr; and a relationship of the guide piece distance Dgp, the frontward distance Df and the rearward distance Dr is:
