The present invention relates to a coaxial cable end connector, which includes an insulating housing, a signal terminal, and a shielding housing. The insulating housing includes a hollow hole, a terminal cavity, and an insulating plate. The signal terminal is disposed in the terminal cavity. The signal terminal includes a flat portion, wherein the flat portion of the signal terminal is electrically connected with an end of an internal conductive wire of the coaxial cable. A through hole is formed on a central region of the flat portion of the signal terminal, and two limiting pillars is disposed around an edge of the through hole of the signal terminal for positioning the internal conductive wire of the coaxial cable. The shielding housing includes a circular portion and a cover, wherein the circular portion of the shielding housing surrounds the insulating housing.
