Abstract
A junction box having a sheathed cable retainer structure is disclosed. The junction box contains pry outs that cover openings at corners of the junction box wherein the pry outs are removed and a sheathed cable or like electrical wiring can pass therethrough. A strain relief bracket having segmented distal bends at opposite ends thereof engages the cable and under bias pushes the cable against an indent formed on a wall inside the junction box opposite the cable.
Claims21
An electrical junction box for receiving a sheathed electrical cable, comprising:
- opposed left and right side walls joined with opposed top and bottom walls joined with a back cover to define an interior cavity with one side open, wherein the walls and back cover form a plurality of corners;
- at least one cable opening proximate to one of the plurality of corners and formed in one of the walls;
- a pry out plate covering the cable opening;
- a strain relief bracket extending across a width of the cavity and disposed immediately abutting the cable opening, wherein at least one end of the strain relief bracket is bent at an angle and includes a curved distal tab;
- and
- wherein when the pry out plate is removed, the sheathed electrical cable passes through the cable opening and into the cavity and the curved distal tab of the strain relief bracket frictionally engages and biases the electrical cable against at least one of the left and right side walls to retain the sheathed electrical cable within the cavity.
An electrical junction box for receiving a sheathed electrical cable, comprising:
- opposed left and right side walls joined with opposed top and bottom walls joined with a back cover to define an interior cavity, wherein the walls and back cover form a plurality of corners;
- a plurality of openings located in at least one of the walls proximate to the corners;
- pry out plates covering the plurality of openings;
- a strain relief bracket at least partially extending across a width of the cavity and attached contiguous with at least one of the walls having the plurality of openings, wherein a curved distal tab of the strain relief bracket is bent at an angle and slightly protrudes into one of the openings of the plurality of openings;
- and
- wherein when at least one of the pry out plates is removed, the sheathed electrical cable passes through the one opening and into the cavity, and the curved distal tab of the strain relief bracket frictionally engages the sheathed electrical cable under bias against one of the opposed left and right side walls to retain the sheathed electrical cable within the cavity.
An electrical junction box for receiving a sheathed electrical cable, comprising:
- a multisided box defined by opposed walls defining an interior cavity, wherein the walls include corners;
- a plurality of wall openings formed in at least one of the walls proximate to the corners;
- pry out plates covering the plurality of pry out openings;
- a strain relief bracket at least partially extending across a width of the cavity and attached contiguously with at least one of the walls having the plurality of wall openings, wherein a curved distal tab of the strain relief bracket is bent at an angle and slightly protrudes into one wall opening of the plurality of wall openings;
- and
- wherein when at least one of the pry out plates is deformed to expose the pry out opening, the sheathed electrical cable passes through the pry out opening and into the cavity, and the curved distal tab of the strain relief bracket slidably engages the sheathed electrical cable under bias against one of the opposed walls defining the interior cavity to retain the sheathed electrical cable within the cavity.
An electrical junction box for receiving a sheathed electrical cable, comprising:
- a multisided box defined by opposed walls defining an interior cavity, wherein the walls include corners;
- at least two openings formed in one of the opposed walls proximate to the corners and at least two openings formed in another opposed wall so that the two wall openings are aligned with the other two wall openings;
- pry out plates covering the plurality of openings in the walls;
- a strain relief bracket at least partially extending across a width of the cavity and attached contiguously with at least one of the walls having the openings, wherein a curved distal tab of the strain relief bracket is bent at an angle and slightly protrudes into one of the openings in the walls;
- and
- wherein when the pry out plates are detached, the sheathed electrical cable passes through the opposed and aligned wall openings and into and out of the cavity, and the curved distal tab of the strain relief bracket frictionally engages the sheathed electrical cable under bias against an indent on one of the opposed walls, and secures the sheathed electrical cable to the junction box.
