An electrical assembly comprising: a backshell having a coupling nut defining a cavity and a cable follower received in the cavity and extending rearward from the coupling nut, the cable follower having a plurality of rearward extending spring fingers extending to distal ends, the spring fingers defining a cable channel configured to receive a cable, the spring fingers being deflectable to provide a clamping force against the cable, the spring fingers being tapered inward to the distal ends to define a generally conical shaped cable channel; a retention feature coupled between the cable follower and the coupling nut, the retention feature allowing the coupling nut to be rotatably coupled to the cable follower such that the coupling nut is rotatable relative to the cable, the coupling nut being configured to be coupled to a front shell of the electrical assembly; and a cavity insert received in the cavity, the cavity insert having a braid lip configured to be mechanically and electrically coupled to a cable braid of the cable, the cavity insert having a keying feature configured to engage the cable follower to secure the relative position of the cavity insert with respect to the cable follower; characterised in that the spring fingers are configured to be spring biased against the cable in different radial directions to substantially center the cable in the cable channel, the retention feature is held in a pocket in the coupling nut and rotatable with the coupling nut about the cable follower, and the retention feature comprising a ratchet feature to rotatably fix the coupling nut to the cable follower at defined ratchet positions. a backshell having a coupling nut defining a cavity and a cable follower received in the cavity and extending rearward from the coupling nut, the cable follower having a plurality of rearward extending spring fingers extending to distal ends, the spring fingers defining a cable channel configured to receive a cable, the spring fingers being deflectable to provide a clamping force against the cable, the spring fingers being tapered inward to the distal ends to define a generally conical shaped cable channel; a retention feature coupled between the cable follower and the coupling nut, the retention feature allowing the coupling nut to be rotatably coupled to the cable follower such that the coupling nut is rotatable relative to the cable, the coupling nut being configured to be coupled to a front shell of the electrical assembly; and a cavity insert received in the cavity, the cavity insert having a braid lip configured to be mechanically and electrically coupled to a cable braid of the cable, the cavity insert having a keying feature configured to engage the cable follower to secure the relative position of the cavity insert with respect to the cable follower; characterised in that the spring fingers are configured to be spring biased against the cable in different radial directions to substantially center the cable in the cable channel, the retention feature is held in a pocket in the coupling nut and rotatable with the coupling nut about the cable follower, and the retention feature comprising a ratchet feature to rotatably fix the coupling nut to the cable follower at defined ratchet positions.
