Enclosure with grommetless strain relief

Abstract

Enclosures with grommetless strain relief are provided, each including a base and a cover. The base has a bottom and four sidewalls arranged to provide an open box-like structure. A first of the sidewalls of the base is configured with a wire routing slot at its perimeter. The cover has a top and four sidewalls arranged to provide an open box-like structure configured to couple with the base, so as to provide a strain relief for an electrical wire passing through the wire routing slot. The wire is pressed against a length of the first sidewall of the base by a first sidewall of the cover. The enclosure may include other features, such as rounded edges in the wire routing path, a wire guide and/or strap to inhibit wire movement between the first sidewalls, and/or one or more locking mechanisms configured to secure the cover to the base.

What is claimed is: 
     
         1 . An enclosure, comprising:
 a base having a bottom, a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall, arranged to provide a first open box-like structure, wherein the first sidewall is configured with a wire routing slot at a perimeter of the first sidewall; and   a cover having a top, a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall, arranged to provide a second open box-like structure configured to couple with the base portion so as to provide a strain relief for an electrical wire passing through the wire routing slot, wherein the electrical wire is pressed against a length of the first sidewall of the base portion by the first sidewall of the cover portion.   
     
     
         2 . The enclosure of  claim 1 , wherein the wire routing slot is configured with a rounded edge over which the wire passes. 
     
     
         3 . The enclosure of  claim 1 , wherein the first sidewall of the base further comprises a wire guide proximate to the wire routing slot and configured to inhibit movement of the wire between the first sidewall of the base and the first sidewall of the cover. 
     
     
         4 . The enclosure of  claim 1 , wherein the first sidewall of the base further comprises a wire strap proximate to the wire routing slot and configured to inhibit movement of the wire between the first sidewall of the base and the first sidewall of the cover. 
     
     
         5 . The enclosure of  claim 1 , wherein the first sidewall of the cover further comprises a wire strap proximate to the wire routing slot and configured to inhibit movement of the wire between the first sidewall of the cover and the first sidewall of the base. 
     
     
         6 . The enclosure of  claim 1 , further comprising a locking mechanism configured to engagingly secure the cover to the base. 
     
     
         7 . The enclosure of  claim 1 , wherein the cover is composed of sheet metal and wherein the base is composed of sheet metal. 
     
     
         8 . An enclosure, comprising:
 a base having a bottom, a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall, arranged to provide a first open box-like structure, wherein the first sidewall comprises a wire routing slot at a perimeter of the first sidewall, wherein the wire routing slot is configured with a rounded edge over which a wire passes;   a cover having a top, a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall, arranged to provide a second open box-like structure configured to couple with the base so as to provide a strain relief for the wire passing through the wire routing slot, wherein the wire is pressed against a length of the first sidewall of the base by the first sidewall of the cover; and   a substrate secured with the base, wherein the wire is electrically coupled to the substrate.   
     
     
         9 . The enclosure of  claim 8 , wherein the first sidewall of the base further includes at least one wire guide proximate to the wire routing slot and configured to inhibit movement of the wire between the first sidewall of the base and the first sidewall of the cover. 
     
     
         10 . The enclosure of  claim 9 , wherein the first sidewall of the base further includes at least one wire strap proximate to the wire routing slot and configured to inhibit movement of the wire between the first sidewall of the base and the first sidewall of the cover. 
     
     
         11 . The enclosure of  claim 9 , wherein the first sidewall of the cover further includes at least one wire strap proximate to the wire routing slot and configured to inhibit movement of the wire between the first sidewall of the base and the first sidewall of the cover. 
     
     
         12 . A lighting electronics enclosure, comprising:
 a base having a bottom, a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall, arranged to provide a first open box-like structure, the first sidewall configured with a wire routing slot at a perimeter of the first sidewall, wherein the wire routing slot is configured with a rounded edge over which a wire passes;   a cover having a top, a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall, arranged to provide a second open box-like structure configured to couple with the base so as to provide a strain relief for the wire passing through the wire routing slot, wherein the wire is pressed against a length of the first sidewall of the base by a first sidewall of the cover;   a substrate secured with the base, wherein the wire is electrically coupled to the substrate via a solder joint and wherein the substrate includes electronics capable of providing power to a light source; and   a locking mechanism configured to secure the cover to the base.   
     
     
         13 . The lighting electronics enclosure of  claim 12 , wherein the first sidewall of the base further comprises a wire guide proximate to the wire routing slot and configured to inhibit movement of the wire between the first sidewall of the base and the first sidewall of the cover. 
     
     
         14 . The lighting electronics enclosure of  claim 13 , wherein the first sidewall of the base further comprises a wire strap proximate to the wire routing slot and configured to inhibit movement of the wire between the first sidewall of the base and the first sidewall of the cover. 
     
     
         15 . The enclosure of  claim 13 , wherein the first sidewall of the cover further comprises a wire strap proximate to the wire routing slot and configured to inhibit movement of the wire along the first sidewall of the cover.
