The invention discloses a connector structure of a cable. The cable includes an inner conductor and a jacket. The connector structure of the cable includes a shell in which an accommodating cavity and on which a first mounting hole, a second mounting hole and an external interface are arranged; and a wiring terminal and a fastener which are put in the accommodating cavity. One end of the wiring terminal is connected with the inner conductor in a sleeving manner, and the other end corresponds to the second mounting hole and is provided with a via hole; and the fastener is made of metal material, is arranged in the via hole in a penetrating manner and extends towards the external interface. The connector structure also includes a first end cover which sleeves the jacket and covers the first mounting hole; and a second end cover which covers the second mounting hole and is detachably fixed to the shell. The connector structure of the cable is small in number of parts realizing electrical connection, is easy to assemble, is stable and reliable in connection, and is convenient to be matched with another component through the external interface to realize connection.
