A weather hood is disclosed having a housing and a plurality of hood segments each formed from a pair of spaced apart pivot arms joined by a shell portion. The hood segments are pivotally mounted on the housing for rotation about an axis passing through the ends of the pivot arms. The hood segments pivot between a retracted position, wherein the hood segments are nested one within another within the housing, and an extended position, wherein the hood segments extend from the housing and are positioned adjacent to each other. Hooks extend from edges of the shell portions, each hook interengaging a hook on an adjacent hood segment or the housing to interlock the hood segments in the extended position and limit their rotation. A spring is connected between the housing to the lowermost hood segment to bias the hood segments into the retracted or extended position.
Abstract:
A device (100) has a base (112). The base (112) has a first jack (161) on its bottom and a second jack (153) on its top. The first jack (161) may be a standard 645-type jack, and the second jack (153) may be a standard RJ11 jack. The base (112) has a bearing surface (114) for engaging a mounting surface (198) of a standard sheet metal panel. A first plug (160) (such as a 645-type plug) is shaped to fit into the first jack (161). The first plug (160) has terminals (164) which are conductively coupled to the second jack (153). The terminals (164) are shaped so as to directly connect to a printed circuit (199a) when the bearing surface (114) of the base (112) engages the mounting surface (198) and the mounting surface is positioned between the bearing surface and the printed circuit. A second plug (152), which may be an RJ11 plug, is shaped to fit into the second jack (153). The second plug (152) has contacts (154) which are conductively coupled to the printed circuit (199a) via the first plug (160) when the second plug is inserted in the second jack (153). The second plug (152) may be attached to the base (112) by a flexible attachment, which may be, for example, a cable (130) or a hinge (270). In one example, the base (212) and the second plug (252) are formed by a single portion of material, and are attached to each other by a living hinge (270).
Abstract:
A customer bridge configuration (110) allows connection or disconnection of customer-side lead wires when the customer wiring is disconnected from the external telephone network, but prevents connection or disconnection of customer-side lead wires when the customer wiring is connected to the external telephone network. A connector (120) is mounted to a housing (112). The connector (120) includes two terminals (123) and at least one movable portion (122) mounted over the terminals. A wire (132) is engaged by the housing (112). The wire (132) extends from a position in a top surface of the housing (112), and may be wrapped within cladding as part of a cable (130) The wire (132) has an end terminating in a plug(152). An RJ11 jack receives the plug (152). The jack (153) provides an electrical connection to an outside circuit (164). The wire (132) is long enough for the plug (152) to reach the jack (153) when the movable portion (122) is in the closed position, but too short for the plug (152) to reach the jack (153) when the movable portion (122) is in the open position. The connector (120) is between the jack (153) and the position in the top surface of the housing (112) from which the cable (130) extends. The movable portion (122) includes holes (124) for insertion of customer-side lead wires. The movable portion (122) has an open (raised) position, and a closed (lowered) position for connecting the terminal (123) to the customer-side lead wires.
Abstract:
An enclosure for telecommunications equipment has a base and a lid pivotally connected to the base. The enclosure has an aperture defined by aperture edges through which one or more wires can be fed. A first elastically deformable insert is attached to a mounting surface on the base and a second elastically deformable insert is attached to a mounting surface on the lid, both adjacent to the aperture, such that when the lid is closed, the first and second inserts deform under contact with each other and with any wires fed through the aperture to reduce the size of gaps between the wires and the aperture edges. In one embodiment, the inserts have slots that enable non-continuous deformations to provide better sealing characteristics.
Abstract:
216-type screws and KS-type screws are two types of fastening devices typically used to restrict access to the chambers of building entrance protector (BEP) enclosures used in telecommunications applications. Access to such chambers is limited to those users who have special tools designed for one or the other type of screw. The present invention is a screw that can be actuated using either the special tools designed for 216-type screws or the special tools designed for KS-type screws. In particular, screws of the present invention have a hexagon-shaped outer surface like a 216-type screw and a hexagon shaped recess with a cylindrical upstanding post in the middle of the recess like a KS-type screw.
Abstract:
Two devices having a latching mechanism of the present invention can be mounted back to back within a single mounting hole in a mounting surface. Each latching mechanism has two or more prongs designed such that they do not interfere with the prongs of another device mounted within the same mounting hole from the opposite side of the mounting surface. In one embodiment, the present invention can be implemented as a retainer for retaining wires, cables, and cables for telecommunications applications. In a preferred embodiment, each retainer prevents access from its side of the mounting surface to the other retainer mounted from the other side of the mounting surface. As such, the present invention provides a security feature for the assembly.
