ABSTRACT:
A protector for protecting the mating plug and socket of connected electrical cords from damage and contamination and which allows quick disconnection of the plug and socket in an isolated chamber. The protector has a tubular housing formed of high impact plastic, preferably transparent, which surrounds the mating plug and socket members of connected electrical cords and resilient end plugs which are slidably received on the cords rearwardly of the plug and socket. The end plugs have a longitudinal slit extending radially from a central longitudinal bore and are installed by pressing them laterally onto the cords then sliding them axially on the cords to press them into the open ends of the tubular housing. When pressed into the ends of the housing, the end plugs define a central chamber surrounding the plug and socket connection and form a seal at the opposed ends of the chamber between the housing and the exterior of the cords. The coefficient of friction between the end plugs and interior of the housing is greater than the coefficient of friction between the end plugs and the cords such that the end plugs remain frictionally engaged with the interior of the housing while allowing relative sliding movement between the cords and end plugs. When the cords are pulled apart, the plug and socket separate completely while enclosed in the sealed chamber to isolate any spark or arc and continued axial movement pulls the end plugs from the ends of the housing.
