Cable connector

Provided is a cable connector, comprising: a housing; an outer conductor at least partially mounted within the housing and defining a first through hole; the insulating shell is arranged in the outer conductor and defines a second through hole; the inner electric conductor is arranged in the insulating shell, an insertion cavity and a connecting hole communicated with the insertion cavity are defined in the inner electric conductor, the inner electric conductor is electrically isolated from the outer electric conductor through the insulating shell, and the first through hole and the second through hole are aligned with the connecting hole in the radial direction; a fastener which is at least partially installed in the connection hole and can be operated to fasten the central conductor of the inserted cable in the insertion cavity; the insulating ring sleeves the outer peripheral surface of the outer conductor, so that the outer braid layer of the inserted cable leans against the outer peripheral surface of th
