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, a trailing end, a cap, an inner bore, and one or more grounding tangs, locking tangs, and flanges extending radially outward from the connector body. According to one embodiment, the flanges extend from the grounding tangs and the locking tangs include free ends. According to a further embodiment, the locking tangs extend from an interior base of the locking tangs. In a further embodiment, a seat extends between the flanges of the grounding tangs and the free end of the locking tangs. One or more cable retaining tangs extend inward from the connector body into the inner bore. The one-piece electrical fitting is stamped and formed from a flat blank of metal. A tab and groove arrangement on the blank facilitates forming the blank into the cylindrical connector body, which is held together by a locking arrangement between the cap and the cylindrical connector body.

One-piece electrical fitting for snap connection

A ninety degree snap fit electrical fitting for enabling rapid snap-fit insertion of an electrical cable to an electrical box. The ninety degree snap fit electrical fitting includes a connector body having a leading end, a trailing end, an internal bore, a box connection arrangement on the leading end, and a cable connection arrangement on the trailing end. A seat on the leading end of the connector body includes a snap ring with an outward extending locking tang. An internal snap ring is secured within the internal bore of the connector body at the trailing end. A cable retaining tang on the internal snap ring is adapted to engage and secure an electrical cable to the trailing end of the connector body.

A one-piece electrical fitting for connecting an electrical cable to a junction box, the electrical fitting including a tubular connector body including a leading end, a trailing end, a cap, an inner bore, and one or more grounding tangs and locking tangs. The grounding tangs include flanges and the locking tangs include free ends. A seat extends between the flanges of the grounding tangs and the free end of the locking tangs. One or more cable retaining tangs extend inward from the connector body into the inner bore. The electrical fitting is stamped and formed from a flat blank of metal. A tab and notch arrangement on the blank facilitates forming the blank into the tubular connector body. The fitting provides electrical continuity between the electrical cable, the fitting, and the junction box and stain relief to resist inadvertent removal of the electrical cable from the fitting.

A liquid-tight and concrete-tight electrical fitting for securing PVC jacketed metal clad (PVC-MC) electrical cable to an electrical box or panel. The electrical fitting includes a tubular fitting body having a threaded inbound and outbound end, an MC ring, a grommet, a bushing, a sealing ring, a locknut, and a gland nut. The grommet includes an inbound end with a conical outer surface and an outbound end with a flat abutment surface. A conical inner surface is provided on the bushing for engaging the conical outer surface of the grommet. The MC ring is a continuous ring including an inbound end, an outbound end, a ring portion, and one or more fingers extending from the ring portion. The fitting facilitates liquid-tight and concrete-tight connection and proper electrical grounding of PVC-MC cable to an electrical box or panel.

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.

A cord grip in which two screw fittings provide a variable volume chamber for compressing a flexible soft durometer grommet held within a flexible annular cord gripping member. The cord gripping member is of a harder durometer than the grommet and has a plurality of fingers for gripping the cord. The combination of the hard durometer cord gripping member and the soft durometer grommet provides positive gripping action and a liquid tight seal on the cord when the variable volume chamber within the fittings is in the compressed state.

Liquid tight cord grip

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.

A spring steel adaptor that improves the ease of use and reduces the time involved in securing electrical connectors to electrical junction boxes. Several embodiments are disclosed which require the use of a zinc die-cast connector having a smoother central section to accommodate the spring steel adaptor. Some of the embodiments employ a spring steel adaptor that is designed to be used in conjunction with any of the standard size threaded electrical connectors that are presently in use in the electrical industry.
