Conductive component structure of rail-type terminal device

A conductive component structure of rail-type terminal device, comprising a conductive component (10), the conductive component (10) having a base section (10a), a first section (11) and a second section (12) connected with the base section (10a) and extending to two lateral sides, the first section (11) and the second section (12) being respectively formed with a bow portion (13), a first portion (14) and a second portion (15) connected with the bow portion (13), at least one of the first and second sections (11, 12) defining a space (30) for receiving a load arm (16) and an elastic unit (20) assembled with the load arm (16), the load arm (16) having a subsidiary section (16a), the elastic unit (20) including a first elastic section (21) and a second elastic section (22), the load arm (16) passing through the first elastic section (21) and at least a part of the second elastic section (22), whereby when the load arm (16) is moved, in response to the motion of the load arm (16), the first elastic section (21) and the second elastic section (22) respectively provide tension effect and tensile effect.
