The invention discloses a cable connector component which comprises an insulating body provided with a plurality of containing cavities, a plurality of conductive terminals which are contained inside the corresponding containing cavities and have the tail parts exposed outside the insulating body, clapboards assembled on the insulating body and the conductive terminals, and a plurality of cables electrically connected with the corresponding conductive terminals, wherein the tail parts of the conductive terminals are supported by the clapboards; the clapboards are provided with a plurality of grooves which are parallel and vertical to the butt joint direction; and part of the cables can be contained inside the grooves parallel to the butt joint direction, and the other part of the cables can be contained inside the grooves vertical to the butt joint direction and is not supported by the clapboards. As the cable connector component is provided with the improved clapboards, and the clapboards are provided with supporting parts for supporting the tail parts of the conductive terminals and core wires of the cables, the reliability of welding is enhanced; and furthermore, the clapboards are provided with cable locating grooves vertical to the butt joint direction, and thereby the locating of the cables is benefited after the cables are bended.
