Cam-style anti-rotation device for connector assembly

Abstract:

An improved anti-rotation device designed to prevent rotation of a first threaded portion of a connector assembly with respect to a second threaded portion of the connector assembly is provided. The anti-rotation device may be an integral part of one end of the connector assembly, so that the anti-rotation device cannot become lost before the first and second threaded sections are coupled together. The anti-rotation key may be rotatably coupled to the first threaded portion and may be easily transitioned from an unlocked position within the connector assembly to a locked position that prevents rotation of the threaded portions relative to each other.
