  • Telecommunications cable
    Patent number: 5073682
    Abstract: A cable for use as aerial service wire having a core of conductors and a load carrier in the form of a plurality of spaced apart tensile reinforcing members spaced from the core as a group laterally on one side of the core. Part of the jacket surrounds the core and is interconnected to another jacket part surrounding the group of filaments. The jacket part surrounding the filament group has a width greater than its thickness so that it may fit within a wedge clamp for stringing purposes. The two parts of the jacket are capable of being separated between the filament group and the core to allow a wedge clamp to be fitted. For this purpose, the cable may be fitted with a non-adherent tape inside the jacket and between the jacket parts with the jacket parts interconnecting around edges of the tape.

  • Connector holders and distribution frame and connector holder assemblies for optical cable
    Patent number: 5071211
    Abstract: A planar connector holder for optical fibers having storage compartments for incoming fibers and a mounting region for connectors to outgoing fibers. Two storage compartments lie back-to-back on each side of a planar base of the holder, the compartments being interconnected for fiber to pass from compartment-to-compartment. The mounting region and the storage compartments are aligned from end-to-end of the holder. With connector mounts mounted in the mounting region, the mounts lie in planes common with the two storage compartments in a depth direction of the holder. Also included is a distribution frame and holder combination in which the holders are mounted in two banks with patch cords extending between the banks and selectively between connectors.

  • Telephone terminal bases
    Patent number: 5061023
    Abstract: A telephone terminal base for vertical mounting and with a front closure that is movable about a horizontal hinge axis to open and close the base. The hinge structure is formed by cooperable hinge parts on front and rear closures, the hinge parts slidable one upon the other along an arc of a circle centered upon the hinge axis. The hinge axis is positioned forwardly of the base and with the hinge parts spaced from the hinge axis, they are disposed entirely within the base. The front closure is preferably hinged to move downwardly from a vertical closed position.

  • Assemblies of tube and fiber units and a unit position control member
    Patent number: 5052773
    Abstract: In an optical fiber organizer, a wall of the organizer, which may be a removable shelf, has apertures for receiving tubes having optical fibers, the aperture having a lateral entry slot. The tubes are moved laterally along the slot, in succession so that the tubes progressively gather together in the aperture. The tubes are then brought together as a bundle by use of a tie wrap which is secured solely around the bundle. In the finished structure, the size of the bundle is too large to allow for its removal from the aperture along the slot.

  • Cable and tape structures therefor
    Patent number: 5039197
    Abstract: A composite tape structure having a metal tape layer and a layer of swellable water blocking material, the two layers bonded together face-to-face. The tape structure is for use as a composite shield and water blocking structure surrounding the core of a cable, preferably a telecommunications cable. One edge region of the metal tape layer may extend beyond the layer of water blocking material so that overlapping edges of the metal tape layer confront each other for bonding purposes when used as shield. The layer of water blocking material may be formed from tape impregnated with or provided with a paticulate swellable material, or the particulate material may be applied directly to and bonded to the metal tape layer.

  • Closures
    Patent number: 5014959
    Abstract: A closure, particularly, a telephone closure base with two closure members and a movable shear locking member. In a closed condition of the closure, aligned apertures of the two closure members may receive the locking member to hold the assembly closed. A part of one of the closure members having the aperture is flexible and tensile and has a flexure position such that, when an opening force is applied to the assembly with the locking member extending through the apertures, the flexible part is flexed under tension and is urged against an opposing surface of the other closure member formed with the corresponding aperture. This flexing action places the locking member mainly in shear while minimizing any bending forces upon the locking member.

  • Method and apparatus for forming metal shield from tape
    Patent number: 4984357
    Abstract: Forming metal shield for cable core in which a metal tape is moved along a passline over a concave forming surface which tapers in a downstream direction. A convex rotating roller lying parallel to an adjacent region of the forming surface urges the tape against the concave surface to form the tape into a laterally curved shape. The tape then moves along the concave surface and through an overlapping die to complete the shape of the shield with the tape wrapped around the core with overlapped edges.

  • Applying jacket material to corrugated metal shields of telecommunications cable
    Patent number: 4980001
    Abstract: In a method of applying a jacket to a metal shield of a cable, the jacket comprises a polyolefin having a modifier provided by a carboxylic acid or its anhydride. As the jacket extrudate passes onto the shield, air pressure is lowered at the surface of the shield to provide intimate overall contact between jacket and shield. Heating, additional to that provided by the extrudate, is employed to raise the outside bonding temperature of the shield up to at least the bonding temperature of the modifier so as to provide a bond between the jacket and the shield.
