Enclosures with grommetless strain relief are provided, each including a base and a cover. The base has a bottom and four sidewalls arranged to provide an open box-like structure. A first of the sidewalls of the base is configured with a wire routing slot at its perimeter. The cover has a top and four sidewalls arranged to provide an open box-like structure configured to couple with the base, so as to provide a strain relief for an electrical wire passing through the wire routing slot. The wire is pressed against a length of the first sidewall of the base by a first sidewall of the cover. The enclosure may include other features, such as rounded edges in the wire routing path, a wire guide and/or strap to inhibit wire movement between the first sidewalls, and/or one or more locking mechanisms configured to secure the cover to the base.

The invention relates to an explosion-proof assembly (20) designed to guide at least one conductor device (21) through a wall in a flameproof manner. The assembly (20) has a bushing part (24) with a bushing opening (48) having a bushing surface (49). The bushing part (24) is arranged in the wall. The bushing opening (48) has an associated connecting body (23) with at least one conductor channel (29) through which a conductor device (21) extends. The connecting body (23) has a connecting portion (30), which is connected to the conductor (22) in a frictionally engaged and/or form-fitting manner by plastic deformation. A first delimiting surface (32) is formed on the plastically deformed connecting portion (30), and the bushing surface (49) defines a second delimiting surface (33). A flameproof Ex gap (34) is formed between the two delimiting surfaces (32, 33) by inserting the connecting portion (30) into the bushing opening (48).

A connector for device that is downsized is provided. The connector for device is configured to be attached to a device housing including a hole and configured to hold an electric wire inserted into the hole, and the connector for device includes a tube-shaped housing into which the electric wire is inserted and which is configured to be inserted into one end of the hole of the device housing, and a front holder configured to be engaged with one end of the tube-shaped housing, wherein the front holder includes an electric wire holding portion to which the electric wire is held, and a locking portion that is continuous with the electric wire holding portion and configured to be engaged with the tube-shaped housing, and wherein the electric wire holding portion is positioned inside the tube-shaped housing in a state where the locking portion is engaged with the tube-shaped housing.

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.

An explosion-proof assembly (20) is provided for guiding at least one conductor device (21) through a wall without ignition transmission. The assembly (20) has at least one bushing part (24) arranged in the wall having one or more bushing openings, each of which is delimited in the circumferential direction by a bushing surface. A connecting body (23) is associated with each conductor device (21) coaxially surrounds a mounting portion of the conductor device (21) in a flamegap-free connection. The connecting body (23) has a first outer delimiting surface and the bushing opening defines a second delimiting surface. A flameproof Ex gap (34) is formed between the two delimiting surfaces by at least partial insertion of the connecting body (23) into the bushing opening. Bushing openings without a connecting body (23) are closed in a flameproof manner by a closure member (70). A securing device (52) secures the connecting body (23) in the bushing opening (48).

When Electricians use MC (metal clad)/flexible armored cables to install an electrical box, the cables must be attached to the box using cable connectors. MC cable screw-in connectors are very difficult to physically insert into MC cable and there is no tool specifically designed to accomplish this task. Instead, Electricians need to insert these screws by hand or use a common wrench while simultaneously pushing on the screw. Other connector types are more expensive and risk damaging cable wires. The present invention is specifically designed to quickly and easily insert MC cable screw-in connectors. With a hex shaped well to fit standard MC cable screw-in connectors and a hollow handle, any length of electrical wire may be passed through the core of the tool so that the tool can be positioned to screw the connectors into the MC cable. While ideal for electrical applications as described above, the ability to pass material through the hollow handle while providing a driving action is not limited to electrical applications.

An electrical box having an enclosure and a conduit hub adapter that is configured to engage a portion of the enclosure. The enclosure defines an opening that is configured to receive an electrical power conductor. The conduit hub adapter is movable with respect to the enclosure from a disengaged position to an engaged position. A retainer may be positioned adjacent the opening to engage the conduit hub adapter when in the engaged position and secure the conduit hub adapter to the enclosure. The conduit hub adapter may be configured for engagement with the enclosure in a single orientation. The retainer may be configured so that it may only be disengaged from the conduit hub adapter from within an interior space of the enclosure. The enclosure may have a second opening with a second conduit hub adapter configured to engage the enclosure adjacent the second opening.

A cable gland and methods for earthing, grounding, bonding, and electromagnetic capability with armored, metal-clad, and metallic-sheathed cable types. The cable gland comprises a gland body, a plurality of extensions, an elastomer seal, a compression member configured to rotate the plurality of extensions towards to the elastomer seal, and an earthing insert mounted in the gland body configured to electrically connect a cable to a neutral and/or grounded conductor. The cable gland is configured to provide an air-tight seal between the exterior of the cable and the elastomer seal through rotation of the plurality of extension upon the elastomer seal. The cable gland may include an o-ring and nut to secure the cable gland to a planar body. The earthing insert comprises a grounding spring in electrical communication with a metallic portion of the cable and a neutral and/or grounded conductor.
