  • Publication number: 20240222060
    Abstract: A fuse assembly having a displaceable pin assembly secured within a cap bore of an end cap of the fuse assembly. The displaceable pin assembly can include a plunger that is selectively displaceable along an axis that is non-parallel to a central longitudinal axis of the first end cap. The plunger can be selectively displaceable between an extended position at which at least a first end of the plunger is outwardly positioned away from an outer surface of the first end cap, and a recessed position at which the first end of the plunger is recessed within, or generally aligned with the outer surface of, the first end cap. The displaceable pin assembly can also include a biasing element that can bias the plunger to the extended position, and a support body that can house at least a portion of the plunger and be securely coupled to the cap bore.

  • Patent number: 11605520
    Abstract: A fuse assembly having an end cap that includes a recessed retention body. The recessed retention body can include first and second retention walls and an engagement surface. The first and second retention walls can extend at least in a generally outwardly direction from the retention surface to an outer surface of the end cap, and extend between first and second ends of the first end cap in a direction that is generally parallel to a central longitudinal axis of the fuse assembly. The engagement surface can have one or more walls that downwardly and outwardly extend in divergent directions from an apex of the engagement surface and toward a corresponding one of the first or second retention walls. The apex can be positioned at a central location between the first and second retention walls, and extends in a direction that is generally parallel to the central longitudinal axis.

  • Patent number: 10680425
    Abstract: A one-part or two-part air terminal for protecting a structure against lightning strikes. A flexible adapter, such as a spring, attaches an upper air terminal to a lower air terminal or a one-piece air terminal and base. The flexible adapter allows a flexible engagement between parts of the air terminal and has an internal passageway. A elongate tether couples parts of the air terminal in case the upper air terminal or one-piece air terminal breaks, so as to avoid a broken part from injuring individuals around. The elongate tether may be a ball chain or other type of chain. The elongate tether runs through the internal passageway of the flexible adapter. A base mounts to the one-part or two-part air terminal and mounts the air terminal to the structure. A grounding wire grounds the base to the grounding rod.

  • Patent number: 9812794
    Abstract: A stamped hotline clamp having two parallel top side walls, two parallel bottom side walls, a hinge pin, a conductor plate, a saddle and an elongated metal shaft. The hinge pin pivotably connects the top side walls to the bottom side walls on one end. At the other end, a standoff separates and connects the top side walls and a contact plate connects the bottom side walls. The bottom side walls pivotably contact the saddle. The conductor plate extends between the top side walls and pivotably contacts the contact plate when the clamp is closed. The top end of the shaft is inserted through an opening in the saddle and threaded into an aperture in the conductor plate. Rotating the shaft in a clockwise direction closes the clamp and rotating the bottom end of the shaft in a counter-clockwise direction opens the clamp.

  • Patent number: 9194409
    Abstract: A disconnect assembly includes a head coupler portion and a tool coupler portion. The head coupler portion includes: a threaded portion on a first part of an exterior surface to connect to a wedge frame, a longitudinal bore, a rod configured to slide longitudinally within the longitudinal bore, and a set of annular protrusions on a second part of the exterior surface. The tool coupler portion includes: a threaded bore configured to mechanically attach the tool coupler portion to the tool, and a channel to receive a head coupler portion. The channel includes a set of grooves corresponding to the set of annular protrusions on the head coupler portion. When the head coupler portion is connected to the tool coupler portion, a ram from the hydraulic tool engages the rod to apply force to an object in the wedge frame.

  • Patent number: 9190741
    Abstract: A hybrid grounding connector is provided which combines the positive attributes of currently used connections. A recess is pre-milled, formed or extruded into the body of a compression connector and the recess is pre-filled with solder. After conductors are installed in the connector, an external heat source is applied to heat the solder until it flows into strands of the conductors and forms a solidified joint of the compression connector.

  • Patent number: 9106030
    Abstract: An electrical disconnect for a utility service that has an internal reversible insulator and a separable power connector. In one position, the insulator may allow the flow of electricity through the separable power connector, but, in a second position, the insulator prevents the flow of electricity through the separable power connector. Because the electrical disconnect is located away from the customer's premises, it is difficult for the customer to reconnect his own power.

  • Patent number: 8932087
    Abstract: A stirrup connector includes a cable connecting device, a clamp, and a control section. The cable connecting device is configured to secure a tap line to the stirrup connector. The clamp secures the stirrup connector to a stirrup. The clamp includes a set of jaws forming an opening that is smaller than a diameter of the stirrup and is configured to snap onto the stirrup when the set of jaws is forced against the stirrup at the opening. The control section is configured to be releasably engaged with a hot stick and to translate a connecting force from the hotstick to the clamp to secure the clamp to the stirrup. The stirrup connector provides an electrical connection between the stirrup and the tap line when the clamp is secured to the stirrup.
