Abstract:
A strain-relieved, watertight cord grip comprising:a. a substantially cylindrical body having a first end and a second end and a bore extending therethrough from said first end to said second end substantially concentric with a longitudinal axis of said cylindrical body, said bore adapted to receive an electrical cord therein;b. said bore being outwardly tapered from a point between said first and second ends to said second end to provide a first frusto-conical wall adjacent said second end;c. said body having an externally threaded portion adjacent said second end and substantially overlying said first frusto-conical wall;d. a deformable bushing having a first end and a second end and a bore therethrough;e. said deformable bushing having a tapered outer surface adjacent said first end, said tapered outer surface of said deformable bushing being complementary to said first frusto-conical wall of said cylindrical body;f. grip means having a base ring at a first end and a plurality of displaceable fingers extending therefrom towards a second end, the tips of said fingers describing at said second end a cord passageway, said grip means adapted to be positioned to align said fingers with said longitudinal axis of said body;g. each of said displaceable fingers comprises:h. first rib means extending from said base ring to said finger tip;i. second rib means, substantially parallel with and spaced apart from said first rib means;j. thin web means connected to and between said first and second rib means whereby said fingers have a reduced cross-section and are more easily displaceable;k. assembly means having a cylindrical body member having a first open end and a second partially closed end and a bore extending from said first end towards said second end;l. a second frusto-conical wall extending from the bore in said assembly means between said first end and said second end to said partially closed end;m. said second frusto-conical wall acting upon said fingers to control the size of said cord passageway; andn. at least a portion of said assembly means bore being internally threaded to threadably engage said body externally threaded portion to assemble said cord grip upon an electrical cord.
