  • Patent number: 9306324
    Abstract: An coaxial cable connector is configured to engage with an outer thread of a threaded connector. The coaxial cable connector comprises an inner sleeve, an outer sleeve arranged around the inner sleeve and a nut arranged around the inner sleeve. The nut comprises a metal sheet integral with an inner flange of the nut, wherein the metal sheet is between the inner flange and a cylindrical surface of the inner sleeve. The metal sheet has a fixed side, close to an outer flange of the inner sleeve, fixed to the inner flange of the nut, and a free side, away from the outer flange of the inner sleeve, abutting against the cylindrical surface of the inner sleeve. An empty gap is between the metal sheet and the inner flange. When the nut comprises an inner thread engaging with the outer thread, the outer flange is configured to be between the inner flange and the threaded connector.
