<p>A rail-based fastening structure for terminal blocks includes a fastening clip, a positioning rail and a bus body. The fastening clip has a base plate and two side plates each extending upward from the base plate and having an engaging hook. The positioning rail includes a bottom plate and two tracks extending upward and then outward from two opposite sides of the bottom plate, so that the bottom plate and the tracks define a valley. The bottom plate has an opening. The bus body deposited in the valley has a slot and two shoulder portions. The shoulder portions are positioned at two sides of the slot and extend toward the slot. The fastening clip is inserted into the opening through the slot so that the engaging hooks engage with the shoulder portions, respectively. Thereby, the rail-based fastening structure allows quick and convenient mounting/dismounting operation, low manufacturing costs and firm installation.</p> |
