Protector for electrical cord connections

Details

Inventors: Coffey, Eugene M.;
Assignee:
Primary Examiner: Schwartz; Larry I.
Assistant Examiner: Nguyen; Khiem
Attorney, Agent or Firm: Roddy; Keneth A.

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.

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a protector for electrical connections which will protect the plug and socket of an electrical cord from damage when they are lying on the floor or ground.
It is another object of this invention to provide a protector for electrical connections which surrounds and seals the plug and socket of electrical cords to prevent corrosion and damage caused by water, mud, and debris.
Another object of this invention to provide a protector for electrical connections which will allow the status of the connection to be easily seen.
Another object of this invention is to provide a protector for electrical connections which will surround and maintain a seal around the plug and socket members of connected cords while they are being disconnected to isolate any spark which occurs during disconnection and prevent the spark from causing an explosion.
A further object of this invention is to provide a protector for electrical connections which is easily and quickly installed and will allow the plug and socket of connected cords to be easily and quickly disconnected by pulling the cords apart axially.
A still further object of this invention is to provide a protector for electrical connections which is simple in construction, economical to manufacture, and rugged and reliable in usage.
Other objects of the invention will become apparent from time to time throughout the specification and claims as hereinafter related.
The above noted objects and other objects of the invention are accomplished by 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
