摘要： A self-backing cable bushing for offsetting an electrical conduit passing through a knock out or opening in a structural member. The bushing has face and backing flanges connected by a living hinge. An annular tubular projection with peripheral ramp lugs extends from the face flange. The cable bushing may be installed by locating the face and backing flanges on opposite sides of the knock out and inserting the ramp lugs into the circular hole in the backing. This face retains backing flange in parallel, closely-spaced relation with the surface of offset between them. The bushing may thus be used to protect an electrical conduit from contacting the edges of a variety of knock out shapes.

摘要： A low profile strain relief cord grip is disclosed. The cord grip may be used in applications where a large number of conductors require their ganging in close proximity to one another in a panel or junction box. This cord grip provides strain relief on the cable, holding the cable from pulling out of the panel or from putting any strain on the terminal connections within. The cord grip is designed to be easily constructed and mass produced and does not require the use of complex dies as do some of the popular cord grips in common use in the industry today. The cord grip provides a liquid-tight seal, allowing its use indoors or outdoors. A wide range of cable sizes may be utilized with one size of cord grip. It utilizes a compressible one-piece grommet having an inner sleeve with lips in contact with the cable and an outer array of wedges that mate with a compression cone for compressing the grommet's periphery in an inward direction to tightly grip the cable in a water tight manner.

摘要： A kit for recessed mounting of one or more electrical components within an electrical floor box. The kit includes a leveling ring for mounting an electrical component within the floor box, a funnel with a keystone opening therein, a trim ring with a recessed surface, a cover, and an optional divider for dividing the electrical floor box into high and low voltage compartments. A keystone opening on the funnel provides access to a low voltage holder. The low voltage holder includes a pocket to accommodate snap-in mounting of a low voltage component therein. The leveling ring enables leveling the electrical component with the floor surface. Fasteners secure the trim ring to the funnel and the leveling ring. Securing the cover to the recessed surface of the trim ring provides a recessed floor box assembly with the cover recessed below the floor surface.

摘要： A one-piece electrical fitting for connecting an electrical cable to a junction box, the electrical fitting formed from a single, flat blank of metal into a cylindrical connector body. The connector body includes a leading end having an exit bore, a trailing end, a cap, an inner bore, and one or more combination tangs including grounding tangs, locking tangs, and flanges extending radially outward from the connector body. According to one embodiment, the trailing end of the fitting includes a rolled edge, and the leading end includes a recessed lip for accommodating an insulating liner within the exit bore. The exit bore in the cap is offset to one side with cable retaining tangs on the fitting configured to push toward the exit bore in order to ease insertion of cables and conductors through the fitting. In a further embodiment, the fitting includes two combination tangs that are positioned 180 degrees apart radially on the fitting body to facilitate easier snap-in insertion into the knockout hole of an electrical box.

摘要： An electrical box assembly for the recessed mounting of an electrical component within a concrete pour area. The electrical box assembly includes a concrete can with an open end. A leveling ring is secured within the concrete can to provide a means of mounting an electrical component level with respect to the concrete surface. A funnel, mountable to the leveling ring, provides an electrical enclosure for enclosing the electrical component and recessing the component below the floor surface. A trim ring secures the funnel to the leveling ring and can. A cover plate closes the concrete assembly. A slot in the cover plate closes the top end of the concrete can while enabling the plug ends of electrical cords to remain installed while the cords are in use. The electrical box assembly enables protective recessed mounting of electrical components well below and level with the surface of the concrete pour.

摘要： An electrical device mounting assembly adapted for mounting of power and low voltage components in a shallow wall cavity to supply a television or similar electronic device. The mounting assembly recesses all high and low voltage components behind the wall surface to render them unobtrusive and out of the way. The mounting assembly includes a mounting frame with a peripheral flange, sidewalls, and a rear wall. A corner of the mounting frame is adapted to mount a duplex receptacle at an oblique angle with respect to the sidewalls. The mounting frame includes cable tie-offs for routing cables and at least one low voltage mount for the mounting of low voltage components. The mounting assembly enables consolidation of all power and signal hookups for TV or home entertainment systems in a single assembly that is recessed within the wall and allows flush wall mounting of a flat panel TV.

摘要： A duplex electrical connector constructed of two body portions with internal bores. The body portions easily assemble and disassemble in a sliding manner, the direction of the assembly and disassembly being substantially at right angles to the axes of the internal bores. A front connector body includes a leading end and a trailing end with a lip, a trailing flange, and a bottom periphery. A tab with an aperture therein extends from the top lip. A rear connector body includes a leading end with a front extension, a boss, a trailing end, and two internal bores extending from the trailing end to the leading end. Sliding assembly of the connector bodies enables minimizing the size of the connector bodies for reducing unit production costs while enabling easy disassembly of the two connector body portions for inspection of internal cable connections.

摘要： An electrical connector for easy insertion of one or more electrical cables through a hole or knock-out of an electrical box. The electrical connector includes a substantially tubular connector body including sidewalls, a leading end, and a trailing end. A recess in at least one of the sidewalls facilitates orientation of the connector to avoid burrs in the knockout aperture of the electrical box. The connector body includes base flange at the trailing end, an inner bore, and a dividing wall. Two flexible gripper arms are formed at notched areas of the base flange on opposing sides of the sidewalls. An inner tooth and an outer tooth are included on each gripper arm. Each gripper arm includes a top wall and an outward extending wing. The connector enables connection of two cables to a single knockout with the dividing wall preventing contact between the cables.
