摘要:
Stiff and soft materials each provide certain advantages when used in the manufacture of separable insulated connectors, such as elbow and T-body connectors. Utilizing a shell or an insert that includes one section made from a stiff material and one section made from a soft material can provide a separable insulated connector that capitalizes on the advantages associated with both types of materials. The stiff materials and soft materials can be placed strategically on the shell or insert of the separable insulated connector to maximize the advantages of each material. For example, the stiff material can be used to form a section of the separable insulated connector where strength and durability is most desirable, and conversely, the soft material can be used to form a section of the connector where flexibility is desirable.

A fuse comprising a fuse body having ferrules at opposing ends, a fuse state indicator located on the surface of the fuse body wherein the fuse state indicator may be temperature sensitive or voltage sensitive and a wire extending from one ferrule to the other ferrule wherein the wire is positioned along the surface of the fuse body. The fuse state indicator senses heat generated by the wire or voltage flowing through the wire.

A recessed light fixture includes an LED module, which includes a single LED package that is configured to generate all light emitted by the recessed light fixture. For example, the LED package can include multiple LEDs mounted to a common substrate. The LED package can be coupled to a heat sink for dissipating heat from the LEDs. The heat sink can include a core member from which fins extend. Each fin can include one or more straight and/or curved portions. A reflector housing may be coupled to the heat sink and configured to receive a reflector. The reflector can have any geometry, such as a bell-shaped geometry including two radii of curvature that join together at an inflection point. An optic coupler can be coupled to the reflector housing and configured to cover electrical connections at the substrate and to guide light emitted by the LED package.

A modular fuse holder for holding a fuse is provided. The fuse includes an insulative body, conductive terminal elements coupled to the body, and a fuse element extending between the terminal elements within the body. The fuse holder includes a main body (34) defining a fuse-receiving receptacle (36) therein, and the receptacle is configured to substantially enclose the fuse within the main body. The main body includes a line side terminal (40) and a load side terminal (42) positioned in the receptacle, and configured to mechanically and electrically engage the terminal elements of the fuse. The main body includes an outer surface (46) and at least one opening (50) extending therethrough. An indicating assembly is mounted to at least one of the fuse body and the main body, and at least a portion of the indicating assembly is exposed through the opening. The indicating assembly provides visual indication of an operative state of the fuse when the fuse is received in the receptacle.

Insulated vacuum switchgear and active switchgear elements therefor are provided with a rigid support structure mechanically isolating a vacuum insulator from axial loads in use without reinforcing or insulating encapsulations. At least one of the elastomeric insulating housing and the support structure directly contacts an outer surface of the insulator. Systems and methods for assembling the switchgear are also provided.
