Description

BACKGROUND

Field

The present disclosure relates generally to electrical box assemblies for electrical cables, and cable connectors that can be installed within or attached to electrical boxes to form electrical box assemblies.

Description of the Related Art

Electrical boxes are mounted in various residential, commercial, and industrial locations depending on the particular application. Electrical cables are commonly supplied to such electrical boxes and are used for connecting wires or conductors to electrical devices or fixtures or conductors in other electrical cables. Current electrical codes typically require electrical cabling to be secured to the electrical boxes. In some electrical box configurations, the electrical cables generally pass through an opening in a wall of an electrical box, also known as a knock-out or a pry-out, and are secured in place by a cable connector or clamp. Conventional cable clamps for armored sheathed cabling differ from cable clamps for non-metallic sheathed cabling, but in either case, some conventional cable clamps generally clamp the cable between a clamping plate and a side wall or bottom wall of the electrical box. Conventional cable clamps for armored sheathed cabling, typically include a stop member to prevent the armored sheath from extending too far into the electrical box.

DETAILED DESCRIPTION

The present disclosure provides descriptions of embodiments for electrical cable connectors used in electrical boxes, electrical boxes to which such electrical cable connectors can be secured, and electrical box assemblies incorporating such electrical cable connectors. The specification and drawings are to be regarded in an illustrative sense rather than a restrictive sense. Various modifications may be made thereto without departing from the spirit and scope of the present disclosure.

Referring to FIGS. 1-4, an exemplary embodiment of an electrical box according to the present disclosure is shown. In this exemplary embodiment, the electrical box 10 has four sides 10a-10d and a bottom 10e. The electrical box 10 can be fabricated from metal, e.g., steel or galvanized steel, or from non-metallic materials, such as plastic. An example of a suitable plastic material is injection molded thermoplastic. In the embodiment shown, the electrical box 10 is a conventional 4×4 square box (or what is also known in the industry as a 4″ square box or a 1900 box), however any suitable sized electrical box may be used for the present disclosure. For example, additional multi-gang boxes, such as a 3-gang box or raceways, may be used for the electrical box of the present disclosure. Further, the depth of the electrical box 10 may vary. For example, the electrical box may be 1¼ inches, 1½ inches, 2⅛ inches, or 3½ inches in depth. The electrical box 10 may also include one or more mounting tabs 20 with threaded or tapped mounting holes, where threaded screws 22 (e.g., 8/32 machine screws) can be inserted to secure a cover, e.g., a blank cover, a switch cover or a receptacle cover, or to secure an extension ring or plaster ring to the electrical box 10. The electrical box 10 may include one or more cable entrance pry-outs 24, seen in FIGS. 2 and 3, that when removed create an opening in the electrical box 10 to permit electrical cables to be inserted into the electrical box 10. The electrical box 10 may also include one or more knock-outs 26, seen in FIG. 1, used to secure cable clamps or cable connectors to the electrical box. The knock-outs 26 can come in many sizes. For example, the knock-outs 26 can be ½ inch, ¾ inch, 1 inch or greater in diameter. To connect the electrical box 10 to electrical ground, a ground screw aperture may be included in the electrical box 10. In conventional 4×4 electrical boxes, the ground screw aperture is typically on a raised surface 10f of the bottom 10e of the electrical box 10, as seen in FIG. 1. The ground screw aperture is typically a threaded or tapped hole for insertion of a ground screw, e.g., an 8/32 machine screw, that is typically color coded as green.

Continuing to refer to FIGS. 1-4, one or more cable connectors of the present disclosure can be mounted inside the electrical box 10. In the exemplary embodiment shown, to mount the cable connector to the electrical box 10, one or more side walls 10a-10d of the electrical box 10 may include one or more mounting tabs 28 that extend toward an interior of the electrical box 10. The one or more mounting tabs 28 are positioned in proximity to the cable entrance pry-outs 24, on for example side wall 10a. In this exemplary embodiment, having the mounting tabs 28 extend into the interior of the electrical box 10 permits the installation of the cable connector of the present disclosure from inside the electrical box.

Referring to FIGS. 5 and 6, an exemplary embodiment of an electrical box assembly according to the present disclosure is shown. In this exemplary embodiment, the electrical box assembly 50 includes an electrical box 10 and a cable connector 100, which may also be referred to as a cable clamp, installed within the electrical box. In the embodiment of FIGS. 5 and 6, the electrical box 10 is configured to receive three cables via three pry-outs 24 and the cable connector is capable of receiving and securing the three cables to the electrical box. However, the electrical box 10 and the cable connector 100 according to the present disclosure can be configured to receive and secure more than three cables or less than three cables. For example, in the exemplary embodiment of FIG. 7, the electrical box assembly 10 is configured to receive two cables via two pry-outs 24 and the cable connector 100 is capable of receiving and securing the two cables to the electrical box. The cable connector 100 is mounted to the electrical box 10 by inserting fasteners 134, e.g., threaded or tapped screws, over slots 28a in the mounting tabs 28 and tightening the fasteners 134.

Turning now to to FIGS. 8-25, an exemplary embodiment of a cable connector according to the present disclosure is shown. In this exemplary embodiment, the cable connector 100 has a frame 110 and one or more cable retaining members 150 that are releasably secured to the frame 110. Referring to FIGS. 8-15, the frame 110 has a front wall 112, a top wall 114 and a bottom wall 116. In another exemplary embodiment, the frame 110 may also include side walls (not shown) secured to the front wall 112, the top wall 114 and the bottom wall 116.

The top wall 114 extends from a top portion of the front wall 112, as shown, and can be integrally formed into the front wall 112 or secured to the front wall. The bottom wall 116 extends from a bottom portion of the front wall 112, as shown, and can be integrally formed into the front wall 112 or secured to the front wall. The front wall 112 of the frame 110 in the embodiment shown in FIG. 8, for example, is configured such that it is oriented substantially parallel to a side wall, e.g., side wall 10a, of an electrical box 10. The top wall 114 may be perpendicular to the front wall 112 or the top wall 114 may be at an angle relative to the front wall 112. In the embodiment shown, the top wall 112 is at an angle relative to the front wall, as seen in FIG. 19. The bottom wall 116 is preferably perpendicular to the front wall 112 so that the bottom wall can rest on the bottom 10e of an electrical box 10. The front wall 112, top wall 114 and bottom wall 116 are configured to form a cavity 118 that can receive one or more cables.

Referring to FIGS. 8, 14 and 15, the front wall 112 of the frame 110 includes at least one wire opening 120 for passing electrical wires, e.g., wires 410 seen in FIG. 35, from an electrical cable 400 within the cavity 118 of the frame 110 into the electrical box 10 for connection to other wires or an electrical device or fixture. In this exemplary embodiment, the front wall 112 has three adjacent wire openings 120, seen in FIG. 35. Each wire opening 120 has a center line 111, seen in FIG. 19, and includes a rounded edge 120a around the periphery of the opening 120 to minimize potential damage to insulation surrounding wires passing through the wire opening 120. Alternatively, the wire opening 120 can include, for example, a rubber or plastic grommet to minimize potential damage to insulation surrounding wires passing through the wire opening 120. The size of each wire opening 120 may vary depending upon a number of factors, including the number of wires within the electrical cable and the diameter of the sheathing of the cable. The front wall 112 also acts as a stop to prevent the cable sheathing, e.g., armored electrical cable sheathing, from passing through the cavity 118 of the frame 110 into the electrical box 10.

Each wire opening 120 in the front wall 112 is aligned with a corresponding box pry-out 24 when the frame 110 is mounted or installed within an electrical box. As a result, a cable 400 can be passed through the pry-out 24 opening into the cavity 118, and wires 410 within the cable 400 can pass through the respective wire opening 120 into the electrical box, as seen in FIGS. 48 and 49. Further, the bottom wall 116 of the frame 110 may include one or more cable rest members 122, seen in FIGS. 8 and 10. Each cable rest member 122 is an arcuate member aligned with a respective wire opening 120 in the front wall 112 to act as a guide to position an electrical cable 400 within the cavity 118, as seen in FIG. 35. Non-limiting examples of electrical cables include BX type cables, MC-PCS type cables, and Greenfield type flexible armored cabling. In the exemplary embodiments shown herein, the cable 400 is a BX type armored cable having, for example, an outside diameter of about ½ inch or greater.

Referring to FIGS. 8, 10 and 12, the top wall 114 of the frame 110 includes a mounting bracket 126 that extends from one edge 114a of the top wall 114 to an opposite edge 114b. The mounting bracket 126 is offset from the top wall 114. The top wall 114 of the frame 110 also includes one or more cutouts 128 that provide access to the cavity 118 of the frame 110. In the exemplary embodiment shown, the top wall 114 has three cutouts 128. Each cutout 128 is generally rectangular in shape and extends from a point proximate the front wall 112 toward the mounting bracket 126 as shown. While the cutouts are shown as rectangular in shape, one skilled in the art would readily recognize that the cutouts can be in any shape suitable to provide access to the cavity 118 of the frame 110. In this exemplary embodiment, the mounting bracket 126 is positioned adjacent the cutout 128. The mounting bracket 126 has an upper surface 136, seen in FIGS. 8, 10 and 12, configured to permit the base portion 154 of the cable retaining member 150 to rest. The mounting bracket 126 includes a plurality of mounting apertures 130, e.g., a threaded or tapped openings, configured to receive mounting fastener, e.g., threaded set screws. More specifically, some mounting apertures 130 are configured to receive mounting fasteners 132 used to secure the cable retaining members 150 to the frame 110 of the cable connector 100, and other mounting apertures 130 are configured to receive mounting fasteners 134 used to secure the frame 110 of the cable connector 100 to the mounting tabs 28 of an electrical box 10 as described above. Extending downward from a rear edge 126a of the mounting bracket 126 are cover tabs 138. The cover tabs 138 are substantially parallel to the front wall 112 and configured so that they rest against a side wall, e.g., side wall 10a, of an electrical box 10 and cover openings formed in the side wall when the mounting tabs 28 are folded into the electrical box.

Referring now to FIGS. 16-18, an exemplary embodiment of the one or more cable retaining members 150 is shown. While the present disclosure shows the one or more cable retaining members 150 as being releasably secured to the frame 110, the present disclosure also contemplates that the cable retaining members 150 may be integrally formed into the frame 110.

Each cable retaining member 150 is a flexible member that is able to flex (typically upwards away from the bottom wall 116 of the frame) while an electrical cable passes into the cavity 118 in the frame 110 imparting little resistance to the forward advancement of the cable within the frame while imparting sufficient resistance to rearward movement of the cable to prevent withdrawal of the cable from the frame. Each retaining member 150 may be provided in various shapes and sizes sufficient to flex while an electrical cable passes into the cavity 118 in the frame 110. Each retaining member 150 includes a base portion 154 and at least one leg extending from the base portion 154. In the exemplary embodiment shown, there are two legs 156 and 158 extending from the base portion 154. The base portion 154 is generally straight and includes an aperture 160 used in securing the retaining member 150 to the frame 110. In an embodiment where the cable retaining member 150 is integrally formed into the frame 110, the base portion 154 of the cable retaining member 150 would be integral with the frame and the legs 156 and/or 158 would extend from the frame.

The first leg 156 has a substantially straight main body 156a that extends from a front edge 154a of the base portion 154 at an angle “α”, and an end portion 156b that is at an angle “β” relative to the main body 156a. As such, the leg 156 is cantilevered from the base portion 154 at the point where the base portion 154 connects to the leg 156. This cantilever permits flexibility of the first leg 156 relative to the base portion 154, which is secured to the frame 110. The angle “α” may depend upon a number of factors, including, the length of the leg portion 156, and the angle between the base portion 154 and a central axis 111 of the frame 110, seen in FIG. 19. As a non-limiting example, the angle “α” can be about 145 degrees, which provides suitable flexibility of the retaining member to allow insertion of a cable into the cavity 118 of the frame 110, while imparting sufficient resistance to rearward movement of the cable to prevent withdrawal of the cable from the frame 110. The angle “β” may depend upon a number of factors, including the angle “α” and the angle between the base portion 154 and the central axis 111 of the frame 110, seen in FIG. 19. As a non-limiting example, the angle “β” can be about 145 degrees. The end portion 156b of the first leg 156 may include an arcuate portion 156c that is configured to substantially conform to an outer periphery of the sheathing of an electrical cable, and to engage the sheathing of the electrical cable.

If the cable retainer 150 includes a second leg 158, the second leg 158 in this exemplary embodiment has a first body portion 158a, a second body portion 158b, and an end portion 158c. The first body portion 158a is substantially straight and extends from a rear edge 154b of the base portion 154 at an angle sufficient to allow the cable retaining member to straddle the mounting bracket 126 so that the second body portion 158b is separated from the body portion 154. A non-limiting example of this angle is about 90 degrees. The second body portion 158b is substantially straight and extends from the first body portion 158a at an angle “ω” relative to the first body portion. The end portion 158c is at an angle “θ” relative to the second body portion 158b. As such, the leg 158 is cantilevered from the base portion 154 at the point where the base portion 154 connects to the leg 158. This cantilever permits flexibility of the second leg 158 relative to the base portion 154, which is secured to the frame 110. The angle “ω” may depend upon a number of factors, including, the length of the first and second leg portions 158a and 158b of the cable retaining member 150, and the angle between the base portion 154 and a central axis 111 of the frame 110, seen in FIG. 19. The angle “ω” should be sufficient to provide suitable flexibility of the retaining member to allow insertion of a cable into the cavity 118 of the frame 110, while imparting sufficient resistance to rearward movement of the cable to prevent withdrawal of the cable from the frame 110. The angle “θ” may depend upon a number of factors, including the angle “ω” and the angle between the base portion 154 and the central axis 111 of the frame 110, seen in FIG. 19. A non-limiting example of the angle “θ” can be about 145 degrees. The end portion 158c of the second leg 158 may include an arcuate portion 158d that is configured to substantially conform to an outer periphery of the sheathing of an electrical cable, and to engage the sheathing of the electrical cable.

In the exemplary embodiment shown in FIGS. 16-18, the retaining member 150 has two legs 156 and 158. Each leg 156 and 158 is connected to an end of the base portion 154 as shown and described above. The legs 156 and 158 are secured to the base portion 154 so that the long surfaces of each leg 156 and 158 are substantially in parallel and capable of flexing while an electrical cable passes into the cavity 118 of the frame 110 imparting little resistance to the forward advancement of the cable. The end portion 156b of the leg 156 and the end portion 158c of the leg 158 engage the cable to impart sufficient resistance to rearward movement of the cable to prevent withdrawal of the cable from the frame 110. The retaining member 150 may be made of metal, e.g., steel or galvanized steel, or from non-metallic materials, such as plastic. An example of a suitable plastic material is injection molded thermoplastic. The retaining member 150 may be made as a single unitary member bent or stamped to a desired size and shape, or the retaining member 150 may comprise a plurality of components joined together with, for example, welds to a size and shape sufficient to retain a cable within the frame 110.

In the exemplary embodiment of the cable retaining member 150 shown, the end portion 156b of leg 156 and the end portion 158c of leg 158 are aligned with the frame 110 so that they can flex when a cable is passed into the cavity 118 in the frame and biased toward a normal state when the cable is fully inserted such that the end portion 156b of leg 156 and/or end portion 158c of leg 158 engage the cable sheathing to impart sufficient resistance to rearward movement of the cable so as to prevent withdrawal of the cable from the housing, as seen in FIG. 35. To accommodate cables having different outside diameters, the legs 156 and 158 can be configured so that the end portions 156b and/or 158c can extend into the cavity 118 and end at different locations within the cavity, such that there is a height difference “H1” between the end portions 156b and 158c, as shown in FIG. 20. To remove the cable from the frame 110, upward pressure can be applied to the legs 156 and 158 of the retaining member 150 so that the end portion 156b and 158c no longer engage the cable sheathing.

Referring to FIGS. 26-29, another exemplary embodiment of the cable connector according to the present disclosure is shown. In this exemplary embodiment, the cable connector 200 is substantially the same as the cable connector 100, except that the cover tabs 138 are replaced with a mounting arm 210 and the mounting bracket 126 does not include mounting apertures 30 for securing the frame 110 of the cable connector 200 to the mounting tabs 28 on the electrical box 10. For ease of description, the common elements between the cable connector 100 and the cable connector 200 will not be repeated, and common element numbers will be the same. In this exemplary embodiment of the cable connector 200, the mounting arm 210 extends from the rear edge 126a of the mounting bracket 126 of the frame 110 in an upward direction, i.e., away from the cavity. The mounting arm 210 is substantially parallel to the front wall 112 so that it can rest against a side wall, e.g., side wall 10a, of an electrical box 10 when installed. The mounting arm 210 includes one or more mounting apertures 212, e.g., threaded or tapped openings, configured to receive mounting fasteners, e.g., threaded set screws, and are used to secure the frame 110 of the cable connector 200 to the electrical box 10. As an example and referring to FIGS. 1 and 42-45, mounting fasteners 214 can be passed through apertures 29 in an electrical box 10, seen in FIG. 1, and threaded into the mounting apertures 212 in the mounting arm 210 of the cable connector 200 and tightened to secure the frame 110 to the electrical box.

Turning to FIGS. 30-32, there may be instances where the cable retaining member 150 may need to be repositioned to receive and secure large diameter cables to the cable connector. To adjust the height position of the cable retaining members 150 relative to the bottom wall 116 of the frame 110, one or more shims 230 can be inserted between the top surface 136 of the mounting bracket 126 and the base portion 154 of the cable retaining member 150 and secured to the frame 110 with the fasteners 132. Each shim 230 has at least one height position to adjust the height position of the of the cable retaining members 150 relative to the bottom wall 116 of the frame 110. In the exemplary embodiment shown, the shim 230 has two height positions. In this exemplary embodiment, each shim 230 is generally rectangular in shape and has a base portion 232, a step portion 234 and a slot 236 extending from the base portion 232 to the step portion 234 so that the shim can be positioned on the frame as described below. The base portion 232 has a height “H2” (seen in FIG. 32) that can raise the legs 156 and 158 of the cable retaining member 150 in the direction of arrow “A” relative to the bottom wall 116 of the frame 110, seen in FIG. 34, by the height “H2.” As shown in FIGS. 33-37, when the base portion 232 of the shim 230 is positioned between the base portion 154 of the cable retaining member 150 and the top surface 136 of the mounting bracket 126, the fastener 132 can be tightened to secure the shim 230 to the mounting bracket 126 of the frame 110 so as to adjust the position of the cable retaining member 150 relative to the bottom wall 116 of the frame 110. Similarly, the step portion 234 has a height “H3” (seen in FIG. 32) that can raise the legs 156 and 158 of the cable retaining member 150 in the direction of arrow “A” relative to the bottom wall 116 of the frame 110, seen in FIG. 34, by the height “H3.” As shown in FIGS. 38-41, when the step portion 234 of the shim 230 is positioned between the base portion 154 of the cable retaining member 150 and the top surface 136 of the mounting bracket 126, the fastener 132 can be tightened to secure the shim 230 to the mounting bracket 126 of the frame 110 so as to adjust the position of the cable retaining member 150 relative to the bottom wall 116 of the frame 110.

Referring to FIGS. 42-45, another exemplary embodiment of an electrical box assembly according to the present disclosure is shown. In this exemplary embodiment, the electrical box assembly 300 includes an electrical box 10 and one or more cable connectors 200. The electrical box 10 and cable connector 200 are described above and for ease of description are not repeated. In this exemplary embodiment, to mount the cable connector 200 to the electrical box 10, the mounting arm 210 of the frame 110 is positioned against a side wall of the electrical box 10 having cable entrance pry-outs 24, for example side wall 10a. The mounting apertures 212 in the mounting arm 210 of the frame 110 is aligned with apertures 29 in the side wall 10a of an electrical box 10 so that the threaded portion of fasteners 214, e.g., set screws, can pass through the apertures 29 and threaded into mounting apertures 212 to secure the frame 110 to the electrical box 10, as shown. When secured within the electrical box 10, the bottom wall 116 of the frame 110 of the cable connector 200 rests on or is adjacent to the bottom wall 10e of the electrical box 10, as seen in FIG. 43.

Turning to FIGS. 46-49, the operation of the cable connector 100 or 200 according to the present disclosure will be described. For ease of description, the operation will be described with reference to the cable connector 200. When wires 410 of an electrical cable 400 are passed through the pry-out openings 24 in the electrical box 10 the wires 410 enter the cavity 118 of the cable connector 200 and then pass through the corresponding wire opening 120 into the interior of the electrical box. As the wires 410 pass through the wire opening 120 into the electrical box, the cable sheathing 402 enters the cavity 118. As noted, the front wall 112 of the frame 110 acts as a stop to prevent the cable sheathing from entering into the interior of the electrical box. As the cable 400 moves forward within the cavity 118, the end portion 156b of leg 156 and the end portion 158c of leg 158 of the cable retaining member 150 can engage the cable sheathing 402. As described above, the cable retaining member 150 is a flexible member that is able to flex (typically upward) while the sheathing 402 of the electrical cable 400 passes into the cavity 118 of the frame 110 imparting little resistance to the forward advancement of the cable 400 within the cavity 118, while imparting sufficient resistance to rearward movement of the cable 400 to prevent withdrawal of the cable from the frame 110. Thus, releasably securing the cable 400 in the cable connector 200.
