Abstract:
A network interface device is attachable to an intermediate field of a building entrance protector unit. The network interface device includes a jack section having a jack which is designed to receive the plug of a standard telephone. The jack includes wire leads which may be connected to any of the terminals on the intermediate field. The jack section is mountable into a base module which is in turn attachable to the intermediate field by wedging a portion of the base module between adjacent terminals on the intermediate field. A plug section is pivotally connected to the jack section by a living hinge. The plug section includes a plug having a pair of conductive blades therein. The network interface device performs a connecting function when the plug is pivoted to a position within the jack, and the conductive blades establish an electrical connection between the wire leads connected to the telephone company network and the wire leads connected to the customer equipment. When there is a need to disconnect the customer from the telephone company network or to test the system, the plug can simply be pivoted out of the jack, and a standard working telephone can be plugged into the jack for line testing purposes.
Abstract:
A network interface unit with a base is disclosed and has a plurality of modular layers mountable on each other in a consecutive manner with each layer having provisions for being hinged. The first modular layer folds over the base and the second modular layer folds over the first modular layer in a manner so as to provide a compact network interface unit.
Abstract:
A security override system for a locked box comprising a hasp portion connected to a bracket slideably mounted within a locked box, the hasp portion extending through an opening in an outer door of the box; the bracket being movable between a closed position, wherein the hasp portion mates with the opening to form a padlock receiving portion, and an open position, wherein the hasp portion does not mate with the opening to enable the selective insertion and removal of a locked padlock in the padlock receiving portion without first unlocking the padlock; a cam member attached to the box and controllable from outside the box; the cam member comprising a pushing portion positioned and dimensioned to cooperate with a corresponding cutout in the bracket such that the bracket is movable between the open position and the closed position by the interaction of the cam member pushing portion with the cutout.
Abstract:
An electrically conductive hinge includes an electrically conductive first plate with a plurality of knuckles having openings. An electrically conductive second plate of the hinge also includes a plurality of knuckles having openings. The pluralities of knuckles are alternatively interlaced, and a hinge pin is inserted into the openings. One or more electrically conductive tabs are provided on the first hinge plate and frictionally engaged against one or more of the knuckles of the second hinge plate. Also, one or more electrically conductive tabs may be provided on the second hinge plate and frictionally engaged against one or more of the knuckles of the first hinge plate. The conductive tabs are resilient and provide good electrical conductivity between the first hinge plate and the second hinge plate. The hinge is particularly advantageous in grounding an electrically conductive cover to an electrical conductive housing.
Abstract:
A retractable weather shield for protecting an outdoor structure from the elements, the weather shield having a base panel; a mounting bracket for mounting the structure to a substrate; the base panel being slidably mounted to the mounting bracket; the mounting bracket having a storage space for storing the base panel in a substantially vertical stored position between the substrate and the structure; the mounting bracket having a guide channel for engaging a corresponding guide member on the base panel and guiding said base panel between the stored position and a substantially horizontal deployed position above the structure for protecting the structure from the elements when in the deployed position; and wherein the shield may further have a telescoping panel being slidably mounted and supported within the base panel, the telescoping panel being stored within the base panel when in a stored position and extending substantially outside the base panel when in a deployed position.
Abstract:
A bracket includes a mounting flange for mounting the bracket to a structure, an elastically deformable, cable-retaining member for engaging a cable passing therethrough, and a plurality of arms connecting the flange to the member for permitting the cable to pass through the member in a first direction, but for preventing the cable from being withdrawn from the ring in a direction substantially opposite the first direction.
Abstract:
A telecommunications protection unit includes a voltage unit having an electrically insulating base configured to house a diode module assembly and a voltage limiting cell therein. The voltage limiting cell and diode module assembly are retained within the housing by a bus clip. The housing includes structure for preventing damage to the voltage limiting cell and diode module assembly during placement of the bus clip thereon. The diode module assembly is a one-piece article including a bus bar and several diodes and terminals which can be used by itself or in a voltage unit to provide desired electrical effects and facilitate assembly of an electrical system such as a telecommunications protection unit. The terminals of the diode module are highly flexible to respond to excessive voltage and sneak current events encountered by telecommunications protection equipment, and the bus clip is constructed to provide a plurality of independently yieldable segments to accommodate diode stacks of variable heights and reduce manufacturing costs.
Abstract:
A foldable wire distribution field is provided whereby a non-connectorized double sided wire distribution field is hingeably connected and foldable over a standard feeder/protector field to eliminate the need for adjacent feeder fields and distribution fields on a backboard, wall or other structure. The foldable distribution field is preferably configured using double sided tool-less insulation displacement type connectors on the distribution side of the foldable field. The double sided terminal block includes double sided insulation displacement terminal strips with a reversible test feature.
Abstract:
A size reduced modular jack housing comprising a body with at least two sides, a back, a top and a front surface; a modular plug body receiving space formed in the back surface and having a top region substantially proximate to the top surface for receiving a modular body plug latch; the body having a notch formed through the front surface and extending towards the back surface; wherein an upper boundary of the notch is defined by a bottom surface of an integrated mounting latch for mounting the housing on a mounting surface; and wherein a lower boundary of the notch is defined by a portion of the housing that is between said top region of the receiving space and the geometric center of the housing.
Abstract:
A fastener for simultaneously mounting adjacently disposed building entrance protectors (BEP) units to a mounting panel and for grounding the units to each other. The fastener includes a tapered and preferably threaded shaft for facilitating securement of the fastener into the mounting panel, such as by screwing or the like. A lip is integrally formed on the shaft and a clamping element, such as a nut, is movably engaged with an untapered opposite end of the shaft so that when rotated about the shaft opposite end, the nut is translated into close proximity with the lip. When mounting tabs from adjacent BEP units are placed between the nut and lip, and the nut is then rotatably tightened, the mounting tabs are placed in electrical contact to provide a grounding connection between the BEPs while securing the adjacent BEPs to the mounting panel.
