Abstract

A conductive component structure of rail-type terminal device includes a conductive component disposed in an insulation case body. The conductive component has a first section and a second section connected with the base section. The first section and the second section are respectively formed with a bow portion, a first portion and a second portion. A load arm and an elastic unit assembled with the load arm are disposed on the first section and/or the second section. The elastic unit includes a first elastic section and a second elastic section. The load arm passes through the first elastic section and at least a part of the second elastic section. When the load arm is displaced or moved, the first elastic section and the second elastic section respectively provide tension (or pushback force) and pulling force effect so as to improve the shortcoming of the conventional terminal device.
