  • Patent number: 10892610
    Abstract: An adjustable transition coupler for coupling AC/MC to conduit, the coupler having a body with a hollow cylindrical section and an extension member with a curved section, the cylindrical section having a slot to allow passage of a stop plate. The coupler has an insulator with a hollow bushing at one end for insertion into a cavity of the cylindrical section and a stop plate extending radially outward, the stop plate movable by an adjustment screw between minimum and maximum deflections. The stop plate stops AC/MC from passage into the cylindrical section. The hollow bushing stops the conduit positioned in the hollow cylindrical section from passage into the extension member. The coupler has a strap with a curved section complementary with the curved section of the extension member so as to secure a range of AC having different outer sheath diameters.

    Abstract: An adjustable transition coupler for coupling AC/MC to conduit, having a body with a hollow cylindrical section and an extension member, the cylindrical section having a slot to allow passage of a stop plate. The coupler has an insulator (armor stop) with a hollow bushing at one end for insertion into a cavity of the cylindrical section and a stop plate extending radially outward, the stop plate movable by an adjustment screw between minimum and maximum deflections. The stop plate stops AC/MC from passage into the cylindrical section. The hollow bushing stops the conduit positioned in the hollow cylindrical section from passage into the extension member. The coupler has a strap to secure AC having different outer sheath diameters. Snap tabs on the insulator fit into holes in the body while a rib on the stop plate passes through a notch in the slot to facilitate installation and minimize movement.

  • Patent number: 10784600
    Abstract: A split, locknut grounding bushing has a first metal bushing portion with first and second ends, a top, a bottom with teeth, an exterior surface with a boss for receipt of a lug, and an interior surface with threads; a second metal bushing portion similar to the first bushing portion, first and second insulators respectively connected to the top of the first and second metal bushing portions. The first and second metal bushing portions pivot with respect to each other at one end and can be fastened to each other at the second end. The threads of the first and second bushing portions can thread onto the threads of a conduit or connector passing through a hole in an electrical enclosure so as to engage the teeth on the bottom of the first and second bushing portions with an interior surface of the enclosure.

  • Patent number: 10601189
    Abstract: A connector assembly including a connector body with a spring clip including a first free end for engaging a side wall of an electrical box upon installation. During insertion of the connector body the first free end engages the knock-out hole perimeter and deforms so as to permit further insertion. Once the connector body is fully inserted, the spring clip cooperates with a lug on the connector body to hold the connector assembly onto the electrical box.

  • Patent number: 10367344
    Abstract: A cable armor stop for preventing cable sheathing of an electrical cable from passing the armor stop while allowing electrical conductors of the electrical cable to pass therethrough has a body with an outer shell, the body having an interior cavity formed by an interior surface of the body, the cavity extending through the body between a front side of the body and a rear side of the body, the cavity reduced by a radially protruding member extending inwardly such that a terminating end of the radially protruding member is spaced a distance from an opposite side of the interior surface closest to the terminating end, the distance being less than a minimum outside diameter of the cable sheathing of said electrical cable. An electrical connector including such a cable armor stop.

  • Patent number: 10240694
    Abstract: A co-molded sealing ring for use in an electrical fitting has an uncompressed state and a compressed state and includes a first segment formed from thermoplastic elastomer and a second segment co-molded to the first segment, formed from a medium-density polyethylene material. A space formed between the first segment and an inner surface of an electrical fitting connector body when the ring is in the uncompressed state, is at least partially filled by a portion of the first segment when the ring is in the compressed state; the second segment having an end surface positioned away from the first segment, the end surface dimensioned for contact by a gland ring so as to urge the sealing ring into the compressed state so that the first segment forms a seal between the inner surface of the connector body and an outer surface of a conduit positioned within the connector body.
