Abstract

A cable entry device for routing both power cables and low voltage cables through an electrical box. The cable entry device includes an elongated base with a front side, a rear side, two ends and a plurality of apertures in each end. The front side of the elongated base includes a base extension extending there from and a cable shield extending from the base extension. The cable shield includes a top and a bottom surface that are each at an angle of approximately 45 degrees with respect to the base. The top surface is closed and the bottom surface includes a circular opening that is sized to accommodate a conventional electrical fitting therein. A raised peripheral wall extends from the rear side of the elongated base.

Claims

1. A cable entry device for routing one or more electrical cables through a wall comprising:

an elongated base having two ends, a front side, and a rear side;

said base including inner apertures and outer apertures at each end;

a base extension extending from said front side of said base, said base extension including a flat face, said flat face of said base extension including a recessed area therein;

a cable shield extending from said base, said cable shield including a top surface and a bottom surface; and

a circular opening in said bottom surface of said cable shield.

2. The cable entry device of claim 1 wherein said top surface of said cable shield is at an angle of 35 to 55 degrees with respect to said front surface of said base.

3. The cable entry device of claim 1 wherein said top surface and said bottom surface of said cable shield are at an angle of 45 degrees with respect to said front surface of said base.

4. The cable entry device of claim 1 wherein said cable shield includes sidewalls extending between said top surface and said bottom surface.

5. The cable entry device of claim 1 including a boss on said base surrounding each of said outer apertures.

6. The cable entry device of claim 1 wherein said circular opening in said bottom surface of said cable shield is sized to accommodate a conventional electrical fitting therein.

7. The cable entry device of claim 1 including a raised peripheral wall extending from said rear side of said elongated base.

8. The cable entry device of claim 7 wherein said raised peripheral wall and said cable shield form a cavity at said rear side of said base, said cavity enabling said cable shield to accommodate an electrical fitting therein.

9. The cable entry device of claim 1 wherein said recessed area is an arcuate shape.

10. The cable entry device of claim 1 wherein said cable entry device is molded in one piece of plastic.

11. The cable entry device of claim 10 wherein said plastic is selected from the group including polycarbonate, polyvinyl chloride, acrylonitrile-butadiene styrene, and polyethylene.
