Abstract

A male coaxial connector of the present invention comprises a conductive insert and a coupling nut. The conductive insert has a front end with an annular flange. The coupling nut includes an inner surface defining a bore, wherein the bore at least partially surrounds the conductive insert and is configured to receive a provided female coaxial connector. The coupling nut further includes a locking member extending from its inner surface. The male connector further comprises a torque washer formed from fiber-reinforced rubber and disposed between the flange of the conductive insert and the locking member. When the coupling nut engages a female coaxial connector, the locking member and the torque washer are compressed against the flange of the insert. The compressed locking member and the compressed torque washer each maintain a tension force between the male and female connectors to help prevent separation of the male and female connectors. The male coaxial connector can be configured to be coupled to an end of the coaxial cable by, for example, crimping or compression.
