Abstract
Electrical wiring box arrangements are provided which include an electrical wiring box and a one-piece cable clamp and electrical wiring device mounting member. The clamp and wiring device mounting member is slideably received in slots in the wiring box wall structure and held in placed against a box wall. The clamp and wiring device mounting member is provided with deflective leg portions which clamp an electrical cable passing through a knock-out opening in the wiring box wall structure. The clamp and wiring device mounting member is further provided with a mounting tab for mounting an electrical wiring device within the box and, in a preferred embodiment, with a grounding wire attachment for use particularly with non-metallic wiring box arrangements.
Claims21
An electrical wiring box arrangement comprising an electrical wiring box in combination with a clamp and wiring device mounting member;
- said wiring box including a wall structure having front to rear walls and a rear wall therebetween which in combination define a chamber having a forward opening for receiving an electrical wiring device, said wall structure including:
- a knock-out region for providing a knock-out opening for receiving a cable, first cable engaging means, and positioning means for positioning said clamp and wiring device mounting member adjacent to said knock-out region in said box wall structure;
- said clamp and wiring device mounting member including:
- securing means coacting with said mounting means of said wall structure for attaching said clamp and wiring device mounting member to said box wall structure, second cable engaging means for coacting with said first cable engaging means to clamp a cable passing through a knock-out opening in said box wall structure, and means for mounting an electrical wiring device on said clamp and wiring device mounting member.
An electrical wiring box arrangement comprising a synthetic resin electrical wiring box and a clamp and wiring device mounting member;
- said wiring box including a wall structure having front-to-rear walls and a rear wall therebetween which in combination define a chamber having a forward opening for receiving an electrical wiring device, said wall structure including:
- a knock-out region for providing a knock-out aperture for receiving a cable;
- a first cable engaging protrusion integrally molded in said wall structure;
- positioning means for positioning said clamp and wiring device mounting member in said box chamber adjacent to said knock-out region;
- said clamp and wiring device mounting member comprising:
- a flexible, resilient bifurcated member having a substantially flat main body portion and two deflective leg portions essentially coplanar with said main body portion, said main body portion having first and second end portions and first and
- second edges, said leg portions contiguous at a first end of each thereof with said first end of said main body portion, said leg portions having a foot portion at a second end of each thereof, said foot portions each comprising a J-shaped region of each leg portion whereby the heel edge of each foot portion provides said second cable engaging means,
- electrical wiring device mounting means including a tab contiguous with said second end of said main body portion,
- electrical grounding attachment means, and electrical conductive pathway means connecting said electrical wiring device mounting means and said electrical grounding attachment means.
