  • Patent number: 5836791
    Abstract: A modular telecommunications terminal block system includes one or more terminal blocks (10) which may be repeatedly installed and removed from a mounting rail (24). Each terminal block (10) employs a housing (12) having a telephone exchange wire carrier and a service wire carrier within the housing. An exchange to be connected to the terminal block (10) is inserted through an opening (36) in the housing and into the exchange wire carrier (20) which is movable between an open position and a closed position. By manually pressing the exchange wire (20) in the closed position, or by installating the terminal block (10) onto the mounting rail (24), the exchange wire is terminated to an exchange wire contact element (170) within the terminal block (10). A service wire is separately terminated within the terminal block and engages a service wire contact element (66, 68).

  • Patent number: 5835658
    Abstract: The fiber optic cable adapter spool is formed to be retained within an end plate assembly of a wire cable splice closure assembly. The adapter spool provides a cable entrance port capable of supporting an optical fiber cable in conventional telecommunication applications. The fiber optic cable is wrapped with a high coefficient of friction, adhesively-backed tape and a layer of mastic sealant before placed in the cable entrance port. The cable entrance port has two sets of annular gripping teeth and a plurality of annular sealing ribs located between the sets of annular gripping teeth. Once the cable has been placed into a cable entrance port, the adapter spool is contracted to cause the two sets of annular gripping teeth to exert radial pressure into either end of the wrapped portion of the cable.

  • Patent number: 5835657
    Abstract: A fiber optic splice closure assembly has a generally elongate casing having two generally parallel side walls, first and second end walls and a generally planar base, the side walls and end walls extending substantially perpendicular to the base. The optical fiber splice tray may include a combination of one or more: lateral pivot assemblies; longitudinal hinge assemblies; alignment bosses; buffer tube receiving channels having a buffer tube retainer; insert retention socket and insert; splice block; tier bracket hinge assembly and interlocking assembly to assist in aligning and securing a plurality of such splice trays together and to secure buffer tubes within the splice tray and assist in optical fiber dressing within the splice tray.

  • Patent number: 5825961
    Abstract: A fiber optic splice closure assembly has two end plate assemblies, and a closure base and a closure cover attached to the end plate assemblies. An adapter is secured within a cable entrance port in the end plate assembly to alter the end plate opening to accommodate a fiber optic cable. The adapter restrains the cable sheath against axial forces and provides a seal between the optical fiber cable, the adapter and the end plate assembly. A bracket assembly is provided to anchor the optical fiber cable strength member to the end plate assembly. The closure provides a mounting bar secured to said end plate assemblies proximate the closure base and a mounting platform secured to the mounting bar.

  • Patent number: 5697194
    Abstract: A modular seal assembly for sealing a circular opening through a wall, usually with one or more conduits (i.e., telecommunication cables) extending through the seal. The assembly includes an outer pressure annulus and a thick inner pressure disc, both of natural or synthetic rubber, EPDM, urethane, or other elastomer. In the outer annulus the elastomer is an annular series of interconnected blocks of length L1 having a central opening of radius R2; a series of pressure bolts compress the blocks axially, expanding the annulus both outwardly and inwardly. The inner disc, which has an outer radius of about R2 and is interlocked with the elastomer blocks of the outer annulus, has a multiplicity of circular layers, much like an onion; the layers are concentric about an opening through which a conduit usually extends.

  • Patent number: 5568686
    Abstract: A lightweight, economical, reliable and adaptable tool for use in joining wire connector assemblies such as those utilized in telecommunications includes a base member including a housing and a cam mechanism with a T-bar pivotally connected with a cam mechanism. Removable wire connector holders are provided which can be interchanged on the base member and force applicators for use with particular wire connectors can be applied to the T-bar. By providing interchangeability for the wire connector holders and the force applicators, the disclosed tool is capable of being utilized with a variety of industry standard wire connector assemblies without requiring multiple tools. In addition, the tool is formed utilizing a simplified construction and is made from materials which reduce the weight, increase the reliability and reduce the cost thereof.

  • Patent number: 5149278
    Abstract: A telecommunications terminal block employs a housing having a number of separate dielectrically isolated chambers disposed therein. Service wires to be connected to a splice cable are inserted into a chamber through openings in the housing and into a movable wire carrier member disposed within the chamber. An actuator member drives the carrier member from a first position, at which the wires are inserted, to a second position where the wires engage a contact element which electrically couples them to the splice cable. The carrier member moves within the chamber so as to allow an electrically insulating medium within the chamber to flow around the carrier and maintain a constant volume of the medium within the chamber. Loss of insulating medium is thereby avoided during connection and reconnection of the service wires allowing improved protection from environmental factors such as moisture, chemicals and other contaminants.
