Abstract:
A wire trough for an enclosure for telecommunications or other electrical equipment (such as a building entrance protector) has a latch that is disengaged by the application of a force between the wire trough and the enclosure to remove the wire trough from its full mounting position within a corresponding mounting channel within the enclosure wall. The latch prevents inadvertent removal of the wire trough from within the mounting channel, which, for example, might otherwise result from applying tension to wires retained within the wire trough. In one embodiment, the wire trough and mounting channel have, along each lateral edge, a tongue and a groove that engage one another to guide the wire trough into the mounting channel. In addition, the wire trough and mounting channels may have male and female dimples that help retain the wire trough within the mounting channel at the full mounting position.
Abstract:
A pivotable work table for use with an electrical junction box is disclosed. The work table has a table member which is pivotally movable between a retracted position within the junction box and an extended position in which the table is oriented perpendicular to the box. The table member is hingedly connected to one or more retention pins which extend from the table member and slidably engage one or more respective bosses attached to the junction box. Coil springs coaxially disposed around the retention pins provide biasing forces which draw the table member toward the bosses and maintain the table member in either the retracted or extended positions.
Abstract:
Electrical connections with terminals on a protector module mounting panel are protectively shielded from the effects of moisture condensation and other deleterious environmental conditions. The panel is placed in a housing having a top opening and a bottom opening, and wire leads are connected to the terminals. A pan member is placed across the bottom opening of the housing, to define a clearance gap between the pan member and the housing. The wire leads are routed through the clearance gap, and the connection terminals are protectively shielded by a sealant material which may be poured into the pan member from outside the panel housing through the defined clearance gap, and allowed to harden.
Abstract:
An electronics system is implemented within a compact enclosure comprising two or more hinged layers. The functionality corresponding to a shelf of a conventional cabinet resides in a corresponding layer. Backplanes are eliminated, each layer having contact surfaces that mate with matching surfaces of adjacent layers when the layers are rotated about their hinges into the closed configuration. Additional interconnection may be made through cabling housed within a special channel or compartment. Each layer may include cooling fans, which are smaller than conventional counterparts (due to shorter convection paths). Expansion may be effectuated by mating additional units of similar conformation in a modular fashion. Optionally, the functionality corresponding to a given layer may be implemented in circuitry integrated onto a single board to reduce cabling and facilitate replacement and repair. Additional functional layers may be stacked along the depth direction as well as the height or width direction.
Abstract:
An electromagnetic interference shield comprises a non-rigid porous metallic material and a conforming element. The non-rigid porous metallic material is shaped by the conforming element to have a top and sidewalls extending downward from the top. The shaped porous metallic material defines a cavity for receiving at least one circuit component therein.
Abstract:
A high-density, small fiber optic enclosure permits the cross-connection and interconnection of optical fibers, through the use of an open-faced compact layering technique. The optical fiber enters an aperture in the bottom of the enclosure which includes a first section attachable to a wall surface, and a second section connected to the first enclosure section by a hinge. The first enclosure section includes an optical fiber splice holder and a plurality of hooks and clips for holding the optical fibers. The second enclosure section includes a plurality of hooks and clips also. The fibers enter the first section, are connected to the hooks and clips, and cross over to the second section and return to the first section and ultimately pass through an exit aperture in such a fashion as to form a plurality of FIG. 8 layers. If the optical fibers are not shielded, it is possible to use two opposing S-shaped fiber tubes to protect them at the crossover between the first and second enclosure.
Abstract:
A connector having a body and an insertion cap. The wire insertion cap is pivotable relative to the body and is positively and releasably engageable with the body by a latching mechanism. The latching mechanism includes inclined surfaces on the insertion cap on the body, which ensures that the insertion cap is retained in the connector body when a force is exerted on a wire retained within the insertion cap.
Abstract:
A wiring trough for an enclosure for telecommunications equipment (such as a building entrance protector) has a male piece adapted to be received by a female piece at a number of different positions to define an opening having different sizes to accommodate different amounts of wiring. As the amount of wiring needed to be handled increases (e.g., as more enclosures are stacked end to end on a wall one on top of the other), the two-piece wiring trough can be reconfigured without having to remove the wiring trough from the enclosure to expand the size of its opening to accommodate the larger amount of wiring.
Abstract:
A strain relief for an insulation displacement connector contains a cap section, a base section, and a base tab. The cap section is movable between an open position and a closed position and has a wire insertion channel for guidedly receiving a wire. The channel has an entrance aperture for entry of the wire into the channel. The open position facilitates entry of the wire into the channel. The base tab is upstanding from the base section and extends into the wire insertion channel when the cap is in the closed position. In this orientation, the wire in the channel is forced by the base tab into contact with a portion of an inner wall of the channel thereby forming a friction fit therebetween. Thus, the wire is restrained in the channel and strain relieved.
Abstract:
A tool-less insulation displacement connector comprising a top section and a bottom section, the top section being movable between an open position and a closed position; a latch member movable between an engaged position and a disengaged position, the latch member maintaining the top section in the closed position when the latch member is in the engaged position; and a releasable security member for preventing the latch member from moving between the engaged position and the disengaged position.
