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 least one 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 is slightly 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.
