Abstract: A universal clamp assembly having a support fitting with arms and a threaded bolt mounted to the arms allowing rotation about a longitudinal axis of the bolt. The bolt is retained against axial movement along the longitudinal axis. A clamp member is rotatably mounted on the bolt between the arms for rotation of the clamp member relative to the support fitting about the longitudinal axis. The clamp member is restrained against axial movement relative to the support fitting and the bolt along the longitudinal axis. The clamp includes a guide opening through which the bolt extends. A keeper is threadedly mounted on the bolt and partially received in the guide opening. The keeper slides in the guide opening along the longitudinal axis and is restrained against rotation about the longitudinal axis of the bolt relative to the clamp member. The keeper is rotatable about the longitudinal axis concurrently with the clamp member.

Abstract: A single bolt deadend anchor clamp for gripping a cable includes a body having a clevis assembly at a first end and a sagging eye at an opposing second end. A middle body extends between the first and second ends, and includes a reinforcing rib. A pocket is adjacent the reinforcing rib for receiving a keeper inserted above the pocket. A biasing member is disposed between the pocket and the keeper for counterbalancing a load between the keeper and the retaining groove. The biasing member is preferably a spring including a cross bar and two sets of coils.
Abstract: A compression connector assembly for securing a cable has a bushing insert and a gripping sleeve. The bushing insert includes a tubular bore, an exterior surface, a conductor receiving end, and a conductor engagement end. The gripping sleeve has an inner recess and an outer surface, and is adjacent to the conductor engagement end. The tubular bore and the inner recess are substantially coaxial, defining a cable securing passageway.
Abstract: A unitized core grip for an electrical connector includes a longitudinal shaft, a plurality of lobes connected by a plurality of web members, a generally triangular center bore, and a plurality of axial grooves. The core grip is defined by a plurality of longitudinally extending, circumferentially spaced lobes, spaced about a longitudinal axis. The plurality of web members are spaced between and connecting the lobes. The generally triangular center bore is defined by the interior surfaces of the lobes and the web members, prior to compression for receiving a cable.
Abstract: An electrical connector for clamping securely onto a threaded shaft, comprising a transformer bar, a connector body, and a clamping component. The transformer bar includes a plurality of conductor bores therein, a distal end, an upper component having at least one setscrew extendable into one of the bores with wrenching on an exposed end thereof, and a lower component with a lower end surface remote from the exposed end of the setscrew. The transformer bar is substantially Z-shaped such that a bottom end of the upper component is adjacent a top end of the lower component. The connector body at the distal end includes at least one boss adjacent the lower surface of the lower component. The connector body also includes first and second connector sides. The clamping component is pivotally mounted by an attachment link to the boss to be selectively located adjacent each of the first and second connector sides.
Abstract: An occupancy sensor is provided with a housing having an interior cavity. A switch is mounted in the interior cavity of the housing and configured for placement in the open and closed positions. A fascia cover plate may be positioned on the housing to enclose the interior cavity. The fascia cover plate has a fascia rib on an interior surface thereof. The fascia rib is arranged to interfere with the switch in the disabled state to prevent positioning of the fascia cover plate on the housing.

Abstract: A receptacle includes a housing with a face member coupled to a base. A mounting bridge with first and second sides is connected to the base by a bottom member extending along a back surface of the base. The mounting bridge includes at least one substantially L-shaped tab formed on the first side of the bridge engaging a front surface of the base remote from the back surface. An upright post located towards the center of the bridge has a circular opening and a plurality of barbs disposed along its outer edges. Snaps protrude from the first and second ends of the base to engage apertures in the first and second sides of the mounting bridge.
