Ends of wires (a, a′) to be connected along their longitudinal directions are linearly placed, and a tape (t) is wound over and around the both wire ends. An adhesive layer of the tape is faced up, and the tape (t) is wound as the wire ends are rolled, thereby connecting the wires (a, a′). Since the tape displays a strong tear resistance in its longitudinal direction, the wires are strongly connected. The tape may contain reinforced fibers to display a stronger tear resistance. The wires (a, a′) are rolled by being held between plates (11, 33) and moving the plate (33) with respect to the plate (11). The tape (t) is placed on an auxiliary base plate (12) and is wound by the rolling movement of the wires (a, a′). The plate (33) is moved back after winding of the tape (t) to untwist the wires (a, a′).

The textile is manufactured by weaving, embroidering, or otherwise integrating a series of conductive, resistive, and non-conductive fibers into the textile and printing a thermoresponsive colorant on or near the resistive fiber. The pattern and physical configuration of the materials composing the textile determine the visual properties of the textile. Electrical power is supplied to the resistive fiber(s) to change the visual properties of the textile. As the resistive fiber warms, the thermoresponsive colorant is warmed beyond a thermal threshold necessary to effect a color change in the thermoresponsive colorant, thereby creating an electronically controllable, visually dynamic textile.

  • Patent number: 6217809
    Abstract: A method for splicing an improved strength tape having longitudinally extended strands comprises the trimming or patterning of the strands of the respective ends that are to be joined so that the ends can be mated together in a meshing arrangement. The two ends are placed in a splicing tray. An adhesive film is interposed between the two ends and the splice tray is closed. The splice tray is placed in a compression molding press which applies a predetermined time-temperature-pressure treatment profile which cures the adhesive film. The resulting splice has essentially the same physical dimensions of the strength tape, and similar stiffness characteristics to that of the strength tape. Further, the strength of the splice is more than sufficient for use in a communication cable. Because the complete splice process can be completed in less than 4 to 5 minutes, the splice can be performed on-line with the use of a strength tape accumulator.

  • Patent number: 5347089
    Abstract: An arrangement for enclosing a branch-off between a pair of cables (2,3,4) comprises a dimensionally recoverable sleeve (5) which can surround the branch-off, and one or more clips (6) which can be positioned about opposed walls of the sleeve to divide the sleeve into channels for the cables. The or each clip (6) is of unitary form and has a pair of legs (8) that are splayed outwardly to facilitate positioning of the clip over the sleeve walls. The or each clip is deformable so that the legs can be forced towards each other after the clip has been positioned on the sleeve walls but is sufficiently rigid, at least in its deformed state, it will resist opening out of the legs under the recovery forces of the sleeve.The invention provides a relatively simple and easy to install enclosure for branch-offs in harnesses for example that are intended to be used in automotive vehicles.

  • Patent number: 5335408
    Abstract: An optical cable portion (10), resident within a cable closure (14), is caused to receive a water blocking arrangement which is effective to prevent water, which enters an internal cable portion (24) through an unintended cut (21) in an outer jacket (18) of a cable portion (20), from entering an interior of the cable closure. A plurality of water blocking materials (30 and 32) are coaxially disposed about the outer jacket and a core tube (26) of the cable portion, respectively, and cooperate with a heat shrinkable plastic tube (34) which substantially covers the water blocking materials to prevent the movement of water from the internal cable portion past the water blocking materials.

  • Patent number: 5266743
    Abstract: Sealing member for an electric cable having an outer relief surface formed by an array of electrical conductors in a spaced apart relationship concentrically laid over an insulating sheath of the electric cable. The sealing member comprises a collar of flexible and resilient material including a plurality of elongated cavities spaced apart by a distance corresponding substantially to a spacing between electrical conductors of the array, and an outer sealing surface of a generally cylindrical configuration. The collar engages the electric cable concentrically, whereby electrical conductors of the array are caused to enter into respective cavities of the collar which is capable of forming a non-leaking union between the electric cable and an adjacent body in a mating relationship with the collar. The invention also extends to a sealing assembly to form a fluid-tight seal between the electric cable and a surrounding enclosure.

  • Patent number: 5251373
    Abstract: A method for protectively enclosing electrical cables, wherein a portion of at least one cable is sealably disposed in the interior of a housing, includes the steps of placing a pressure-relief valve in communication with the housing interior, the pressure-relief valve being selected to pass an encapsulant therethrough on exposure to a predetermined pressure in said housing interior, and introducing an encapsulant under pressure into the housing interior until the encapsulant passes through the pressure-relief valve. The encapsulant introduction step is practiced by providing a pump having an inlet and an outlet, placing the pump inlet in communication with the housing interior and supplying encapsulant to the pump inlet directly from a bulk encapsulant container.

  • Patent number: 5235134
    Abstract: A method and apparatus for sealing a splice enclosure to protect cable splice connections retained therein. A sealing member is a single piece body integrally formed of a suitable material which resists detrimental environmental effects and is resiliently compressible in an axial direction to seal the splice enclosure. Axial compression of the sealing member is employed to create sealing forces both about the outer periphery of the sealing member and between the sealing member and cables projecting therethrough. The axial compression is applied to the sealing member by a seal neck member which presses the sealing member into a shell member. A retainer plate may optionally be interposed between the sealing member and a retaining edge part of the shell member. A buffer ring may optionally be interposed between the sealing member and a compressing surface portion of the seal neck member.

  • Patent number: 5194692
    Abstract: A cable coupling, particularly for data buses, includes a transformer and resistors to which the cables are directly wired. The components and all electrical connections are enclosed in a heat shrinkable tubing or sleeve filled with liquid encapsulant. Upon application of heat, the tubing shrinks causing the encapsulant to fill all voids between components. The encapsulant is then cured to provide an uncased coupling assembly which protects the components and electrical connections from breakage, while eliminating the need for a separate rigid housing. An overbraided shield and environmental seal may subsequently be added to provide further protection for the coupling.
