A connector assembly includes a cable connector (1), a cable (2), ferrule elements (3) and a conductive contact (4). The cable has a central conductor (21), an insulation layer (23) surrounding the central conductor, a braiding layer (25) surrounding the insulation layer and a cable sheath (27) surrounding the braiding layer. The ferrule elements annularly cover a forward end of the cable, and include an annular insulative first ferrule (31), an annular metal second ferrule (33) and an annular metal third ferrule (35). The first, second and third ferrules engage with the central conductor, the insulation layer and the braiding layer, respectively. The central conductor electrically connects to the contact. The contact and ferrules are inserted into the cable connector. This assembly allows the cable connector to be easily assembled to the cable and provides good electric performance of the cable.
