Access door hinge attachment

A device for connecting standard plastic covered fiber optic cable and armored fiber optic cable to a housing for electrical or electronic equipment. The device consist of a portion of the housing having a passage between an exterior surface of the housing and a interior surface of the housing. At the interior end of the passage is an aperture sized to receive a standard plastic covered fiber optic cable. The passage is tapered such that the interior end has a smaller diameter than the exterior end and the passage is threaded. A bushing is received in the passage. The bushing has a passage through its center through which the fiber optic cable passes. One end of the bushing is threaded and has an aperture in the center thereof sized for receiving a standard plastic covered fiber optic cable. The threaded end of the bushing also includes a longitudinal slot. As the bushing is screwed into the housing passage the slot compresses causing the aperture at the end of the threaded portion of the bushing to clamp around the fiber optic cable. The clamping action physically connects the fiber optic cable to the electrical equipment housing.
