Abstract

An improved anti-rotation device and connector assembly designed to prevent rotation of a first threaded portion of the connector assembly with respect to a second threaded portion of the connector assembly is provided. The anti-rotation device and connector assembly include features that guide and smooth the transition of the anti-rotation device into a position extending through the first and second threaded portions. The anti-rotation device may extend through a tab/groove interface between the first and second threaded portions, or the anti-rotation device may engage opposing interfacing edges of the first and second threaded portions along the length of the anti-rotation device. Once the anti-rotation device is installed through the first and second threaded portions, the anti-rotation device may prevent rotation of the threaded portions relative to each other.
