Abstract: Disclosed are a novel cable and a cable-sealing structure of a connector. The novel cable includes a conductor, an insulating layer, a shielding layer, an outer sheath, and a sealing protection ring. When the cable is installed inside a connector body, a circular seal is hooped outside the outer sheath at an area corresponding to a position of the sealing protection ring. When the circular seal presses the outer sheath of the cable, the sealing protection ring can support the outer sheath, so that the outer sheath may not be deformed. After long-term use or a high-temperature aging test, the outer sheath of the invention has a much smaller shrinkage of a diameter than an outer sheath without the sealing protection ring, therefore, the sealing performance and the safety of the connector are improved, and the service life of the connector is greatly prolonged.
