Protective cable frame for use with low voltage bracket or electrical box
A protective cable frame for providing a portal for routing low voltage cables through a wall. The protective cable frame includes a substantially rectangular frame portion with an inner periphery having a rounded surface, two ends, and arms extending from each end. The arms include an outer bore and an inner slot therein. The inner slots enable insertion of fasteners for direct mounting of the cable frame to a low voltage bracket or an electrical box and permit squaring of the cable frame with respect to the wall. The outer bores in the arms of the protective cable frame enable receipt of fasteners for mounting a cover plate thereto. The protective cable frame is capable of receiving low voltage cables for routing them through a wall to an adjacent room. The rounded surface on the inner periphery provides a gentle bend radius to cables routed there through.
1. A protective cable frame for use with a low voltage bracket or electrical box for providing a portal for routing low voltage cables through a wall comprising:
a substantially rectangular shaped one-piece frame member including two ends, an arm extending from each of said ends, and an opening therein;
said frame member including an inner periphery surrounding said opening and an outer periphery;
an outer bore and an inner slot aligned along a central longitudinal axis through said frame member;
a longitudinal flange extending around said outer periphery of said frame member;
said frame member including a forward peripheral flange extending to a front edge and a rearward peripheral flange extending to a rear edge; and
a substantially broad curved surface on said inner periphery of said frame member extending from said front edge to said rear edge.
2. The protective cable frame of claim 1 wherein said longitudinal flange is coplanar with each of said arms.
3. The protective cable frame of claim 1 including two ears extending from each of said arms.
4. The protective cable frame of claim 3 wherein each of said ears include apertures therein.
5. The protective cable frame of claim 1 including
curved shoulders on said frame member;
a flat center portion on said inner periphery of said frame member; and
curved inner corners on said inner periphery of said frame member.
6. The protective cable frame of claim 1 wherein
said arm includes two sides; and
said outer bore in said arms includes a countersunk area on each of said sides of said arms.
7. The protective cable frame of claim 1 wherein said arms include a width no greater than 0.059 inch.
8. The protective cable frame of claim 1 wherein said longitudinal flange includes a width no greater than 0.059 inch.
9. The protective cable frame of claim 1 wherein said broad curved surface includes a width no less than 0.35 inch.
10. The protective cable frame of claim 1 wherein said broad curved surface includes a radius no less than 0.06 inch.
11. The protective cable frame of claim 1 wherein
said outer bores in said frame member are aligned along a central axis; and
said outer bores in said frame member of a spacing and pattern to match the spacing and pattern of the apertures in a conventional decorative electrical box cover plate.
12. The protective cable frame of claim 1 wherein
said inner slots in said frame member are aligned along a central axis; and
said inner slots in said frame member of a spacing and pattern to match the spacing and pattern of the apertures in a conventional low voltage bracket or electrical box.
13. The protective cable frame of claim 1 wherein said inner slots include a width of at least 0.57 inch.
14. The protective cable frame of claim 1 wherein said one-piece frame member is molded in one piece of plastic.
15. The protective cable frame of claim 14 wherein said plastic is selected from the group including polycarbonate, polyvinyl chloride, acrylonitrile-butadiene styrene, and polyethylene.
16. The protective cable frame of claim 1 wherein said inner periphery of said protective cable frame includes a center a curved surface extending away from each side of said center, said curved surfaces providing a gradual bend radius to any cables extended through said opening of said protective cable frame.
17. The protective cable frame of claim 1 wherein said longitudinal flange and said forward peripheral flange of said protective cable frame fit entirely within a recessed area of a conventional decorative electrical box cover plate when said cover plate is secured to said protective cable frame.
