Abstract

Disclosed herein is a coaxial cable interface port locking terminator including an outer terminator housing and an inner connector body housed within the outer terminator housing. The coaxial cable interface port locking terminator further includes a ratcheting device in operable communication with the outer terminator housing and the inner connector body, the ratcheting device preventing rotation of the outer terminator housing with respect to the inner connector body when the outer terminator housing is rotated in the first direction, the ratcheting device including at least one separate component from the outer terminator housing and the inner connector body. Furthermore, rotation of the outer terminator housing in a second direction does not cause rotation of the inner connector body in the second direction.
