Abstract
A liquid tight connector for pass through cable, tubing or rods includes a body, a compression nut and a gland. There are fingers on the body with flats and triangular ends which cradle the gland and grasp cable, tubing or rods in a liquid tight manner tightly enough to provide strain relief. Spherical bumps with pawl like flats hold the compression nut free of the likelihood of loosening once engaged. The triangular configuration of the ends of the fingers enables improved strain relief and adapts to a large selection of cable, tubing or rod diameters.
Claims14
A liquid tight connector to engage a substantially elongated round object in liquid tight engagement in an opening, said liquid tight connector including a body, said body including a front portion and an end portion, said front portion and end portion having an open passage therethrough, means to engage said end portion in said opening, said front portion including an outer extremity;
- an inner extremity;
- a set circumferential fingers;
- and threads, a gland, said gland being thin;
- flexible;
- and having a central passage therethrough, means in said front portion to engage said gland in said body surrounding said open passage, said fingers having an integral inwardly facing longitudinal portion;
- and an end portion, said finger's end portion triangular in transverse cross section;
- and extending to and defining said front portion's outer extremity, said front portion's threads located at said inner extremity, said gland when engaged in said front portion of said body and said fingers not compressed is cradled by said inwardly facing longitudinal portions and within said triangular end portions;
- and said inwardly facing longitudinal portion of said fingers substantially parallel to said gland and radially offset from said gland, said fingers to liquid tight engage said elongated round a compression nut, said nut including internal threads;
- a sloped internal surface;
- and an object receiving opening therethrough, said compression nut's internal threads engagable on said front portion threads, at least one spherical bump on said sloped internal surface, said at least one spherical bump also including a flat bearing surface, said flat bearing surface acting as a ratchet to lockingly engage said fingers, said fingers cammable over said at least one spherical bump, and said gland compressible within said fingers to liquid tight lockingly engage said elongated round object as said compression nut is screwed down over said fingers on said front portion's threads as said fingers cam over said spherical bump and said bearing surface, said spherical bump and said bearing surface engage said fingers to prevent unscrewing of said compression nut form said front portion.
