An assembly type cable trough manufactured by a no-iron frame continuous extrusion molding method is provided to minimize the penetration of moisture into the inside of the trough. In an assembly type cable trough manufactured by a no- iron frame continuous extrusion molding method, an assembly protrusion part(3) protruded toward a bottom side at both ends of a top surface(5) is formed with a height higher than a bottom surface(6) in a top plate. A plurality of cavity parts(2) is formed on a center body(4) of the top plate. A bottom plate is constructed with a width equal to a width(w) of the protrusion part at both sides of the top plate. An assembly structure(15) is connected to a line plate at a top surface part(13). A plurality of cavity parts(16) is formed on a body(14) of the bottom plate. A plurality of protrusion units(21) is formed on a top part and a bottom part of the line plate to be assembled to an assemble structure(15). A plurality of cavity parts(22) is formed inside the body(14) of the line plate. And, the assembly type cable trough is connected through a connection unit(30) composed of a clamp in a shape of L and a bolt/nut by connecting the line plate to the bottom plate.
