ABSTRACT:
In a coaxial cable connector assembly, having a connector sleeve or retaining end of a coaxial cable and a coupling member between the sleeve and a terminal port to draw the sleeve into engagement with an end of the port, an internal locking device is made up of an annular groove formed along an internally threaded portion of the coupling member and a compressible washer which is pre-assembled in the groove, the coupling member having a male threaded end complementary to the internally threaded portion and washer so that when advanced through the internally threaded portion and washer will increase the torque loading between the coupling member and sleeve to resist accidental loosening or disengagement therebetween. The washer is an endless ring and formed in varying cross-sections for insertion into close-fitting engagement with the groove and may be utilized alone or in combination with seal and spring members at the interface between the male threaded end of the port and the internally threaded portion of the coupling member. In a modified form, an endless compressible liner is employed in place of the washer and groove to resist accidental loosening or disengagement between the post and coupling member.
