Press fit outlet junction box with means for detachably interlocking with electrical cord

Claim 2

An electrical receptacle for installation in a cavity behind an exposed surface of a building, said receptacle comprising: a cylindrical shaped housing having front and rear ends, said front end being arranged substantially flush with the opening in said surface of said building, a first socket holder fitted into said receptacle and having prong receiving sockets embedded therein, said prong receiving sockets communicating with openings in said rear end of said housing for receiving the prongs of an electric cord, said prong receiving sockets and said openings in said rear end of said housing being of similar arcuate configuration, means mounted within said housing adjacent said socket holder for interlocking with prongs of an electric plug inserted through said openings in said rear end of said housing for firmly holding said prongs in said receptacle, said means for interlocking with prongs of an electric plug comprising arm members extending from the closed end of said housing inwardly thereof and provided with tabs along its length one engaging with an indentation in each of the prongs of the electric cord upon inserting of said prongs in said receptacle, said interlocking means being rendered ineffective upon a predetermined rotatable movement of the prongs in said openings in said housing.

Claim 3

The electrical receptacle of claim 1 wherein said interlocking means is rendered ineffective upon predetermined rotatable movement of the prongs in the opening in the housing by moving out of the indentation in the prongs.

Claim 4

The electrical receptacle of claim 1 in further combination with: a pair of spring clips fixedly mounted at diagonal positions on the outside of said housing, each of said spring clips comprising an arm member fixed at one end to said housing and free to flex outwardly from said housing at the other end, an open cylindrical holder for receiving said receptacle, said holder being provided with a strap attached to its outside surface for attaching to studding behind the exposed surface of the building, and a pair of clips fixedly mounted at diagonal positions on the outside surface of said holder, each of said clips engaging and interlocking with a different one of said arm members for holding said receptacle in said cavity and flush with the exposed surface of the building.

Claim 5

The electrical receptacle set forth in claim 3 wherein said arm members of said spring clips interlock with said clips of said holder within the cavity extending through the exposed surface of the building.

Claim 6

The electrical receptacle of claim 3 in further combination with a cover plate mountable over the front end of said receptacle for sealing closed said housing, said cover plate having a second socket holder fastened thereto for extending within said housing, and means for electrically connecting with said housing said second socket holder to said first socket holder.

Claim 7

The electrical receptacle of claim 1 wherein said interlocking means is rendered ineffective upon predetermined rotatable movement of the prongs in the opening in the housing by moving out of the indentation in the prongs.

Claim 8

An electrical receptacle for connecting together in an interlocking arrangement two electrical cords, said combination comprising: a cylindrical shaped housing having first and second ends, said first end being connected to one of an electric cord, a first socket holder fitted into said housing and having prong receiving sockets embedded therein for connection to said one end of said cord, said prong receiving sockets communicating with openings in said second end of said housing for receiving the prongs of a second electric cord, said prong receiving sockets and said openings in said second end of said housing being of similar arcuate configuration, and means mounted within said housing adjacent said socket holder for interlocking with prongs of an electric plug fastened to said second electric cord inserted through said openings in said second end of said housing for firmly holding said prongs in said housing, said means for interlocking with prongs of an electric plug comprising arm members extending from the closed end of said housing inwardly thereof and provided with tabs along its length one engaging with an indentation in each of the prongs of the electric cord upon inserting of said prongs in said receptacle, said interlocking means being rendered ineffective upon a predetermined rotatable movement of the prongs in said openings in said housing.

Claim 9

An electrical receptacle for connecting together in an interlocking arrangement two electrical cords, said combination comprising: a cylindrical shaped housing having first and second ends, said first end being connected to one of an electric cord, a first socket holder fitted into said housing and having prong receiving sockets embedded therein for connection to said one end of said cord, said prong receiving sockets communicating with openings in said second end of said housing for receiving the prongs of a second electric cord, said prong receiving sockets and said openings in said second end of said housing being of similar arcuate configuration, and means mounted within said housing adjacent said socket holder for interlocking with prongs of an electric plug fastened to said second electric cord inserted through said openings in said second end of said housing for firmly holding said prongs in said housing, said means for interlocking with prongs of an electric plug comprising arm members extending from the closed end of said housing inwardly thereof and provided with tabs along its length one engaging with an indentation in each of the prongs of the electric cord upon inserting of said prongs in said receptacle, said interlocking means being rendered ineffective upon a predetermined rotatable movement of the prongs in said openings in said housing.
