ABSTRACT:

TECHNICAL FIELD
The present invention relates to electrical safety devices and more particularly to an extension cord plug cover for sealing the connected plug and socket ends of two extension cord in a watertight manner; the extension cord plug cover including a two-piece, hard plastic, closeably securable, clamshell housing including two hollow half clamshell members hingedly connected and each provided with two cord passage openings positioned such that each cord passage opening of one of the two hollow half clamshell members are in alignment with one of the two cord passage openings of the other of the two hollow half clamshell members when the two hollow half clamshell members are pivoted and closeably secured into a closed configuration, each of the two hollow half clamshell members being filled with a resiliently, shape conformable closed cell foam having contoured plug/socket receiving cavities formed therein, the closed cell foam being sufficiently deformable to form a watertight seal around a plug end of one extension cord and a socket end of another extension cord to be positioned within the extension cord plug cover when the two hollow half clamshell members are pivoted and snap closed into the closed configuration.
BACKGROUND ART
It is often necessary to supply power in an out of the way location to hook multiple extension cords in series by connecting the plug end of one extension cord into the socket end of another extension cord. Although this provides an adequate electrical connection, it is often dangerous to have an unsealed electrical connection when rain or snow are present on the ground. It would be desirable, therefore, to have an extension cord plug cover that was sealable over a connected extension cord plug and socket to provide a watertight seal therearound.
GENERAL SUMMARY DISCUSSION OF INVENTION
It is thus an object of the invention to provide an extension cord plug cover that includes a two-piece, hard plastic, closeably securable, clamshell housing including a two-piece, hard plastic, closeably securable, clamshell housing including two hollow half clamshell members hingedly connected and each provided with two cord passage openings positioned such that each cord passage opening of one of the two hollow half clamshell members are in alignment with one of the two cord passage openings of the other of the two hollow half clamshell members when the two hollow half clamshell members are pivoted and closeably secured into a closed configuration, each of the two hollow half clamshell members being filled with a resiliently, shape conformable closed cell foam having contoured plug/socket receiving cavities formed therein, the closed cell foam being sufficiently deformable to form a watertight seal around a plug end of one extension cord and a socket end of another extension cord to be positioned within the extension cord plug cover when the two hollow half clamshell members are pivoted and snap closed into the closed configuration.
Accordingly, an extension cord plug cover is provided. The extension cord plug cover includes a two-piece, hard plastic, closeably securable, clamshell housing including two hollow half clamshell members hingedly connected and each provided with two cord passage openings positioned such that each cord passage opening of one of the two hollow half clamshell members are in alignment with one of the two cord passage openings of the other of the two hollow half clamshell members when the two hollow half clamshell members are pivoted and closeably secured into a closed configuration, each of the two hollow half clamshell members being filled with a resiliently, shape conformable closed cell foam having contoured plug/socket receiving cavities formed therein, the closed cell foam being sufficiently deformable to form a watertight seal around a plug end of one extension cord and a socket end of another extension cord to be positioned within the extension cord plug cover when the two hollow half clamshell members are pivoted and snap closed into the closed configuration.
