The invention belongs to a current-carrying entire dropper in a trunk line electrification contact system, and in particular relates to a method for designing a carrier cable dropper wire clip of the current-carrying entire dropper. The carrier cable dropper wire clip is characterized in that: the carrier cable dropper wire clip integrally has a bilaterally symmetrical structure of which at leastone end is provided with an opening so that the left side and the right side of the carrier cable dropper wire clip form a semicircular wire clip structure; an in-line bolt hole is reserved at the lower end of the opening; a guide groove is reserved on the middle part of the vertical upper end of the opening; the two outer sides are provided with a turned-over edge structure respectively; the lower end of the carrier cable dropper wire clip is provided with the opening; two pressing ribs are arranged on the middle part, vertical to the upper end, of the opening; and the size of the opening isslightly smaller than the diameter of a carrier cable. The carrier cable dropper wire clip has the characteristics of convenient use, rational structure and reliable use.
