The utility model discloses a connector for carbon fiber compound core wires, which is a two-layer structure. The inner-layer structure consists of a cylindrical wire pressing sleeve and a conductive connector fixed and connected at the outside of the cylindrical wire pressing sleeve; a combined inner-layer structure consisting of a tensioner head, a tensioner sleeve, an inner top nut and an inner cone is arranged in the inner cavity of the wire pressing sleeve; one end of the tensioner sleeve is provided with a conical cavity with the conicity equal to the exterior conicity of an inner cone sleeved therein; internal threads matching with the external threads of the tensioner head and the inner top nut are arranged in the inner cavity of the other end of the tensioner sleeve; a central through hole is arranged on the inner cone for the carbon fiber compound core to thread; an annular cavity for an aluminium twisted wire to thread is arranged between the wire pressing sleeve and the tensioner sleeve; a lug boss for propping and pressing the inner cone is arranged on the inner top nut between the inner top nut and the inner cone; and connectors occluded with each other are arranged between the inner top nut and the tentionser head. The connector is particularly suitable to be used as a connector for connecting carbon fiber compound core wires used for transmission of super-high voltage and ultra-high voltage power.
