ABSTRACT:
An electrical plug assembly providing internal, adjustable gripping means and sealing means for electrical cords of various sizes. The internal, adjustable gripping means is a three-jaw grip assembly using pie-shape jaws which are slidably mounted on tracks and moved towards and away from the center of plug body to form a gripping circle around cords of various sizes. The cord seal consists of a notched rubber bushing formed between two rings. As the cover is tightened over the clamping jaws, the rings on either sides of the rubber bushing are urged together causing the bushing to collapse inward and seal the cord. The cord seal also provides means for locking the cord seal in place and increasing torque needed to remove the cover.
